GB2RS News Sunday the 8th of December The news headlines: Take part in the RSGB Construction Competition A new edition of RadCom Basics has been published A busy week with GB24YOTA hosted by many groups for YOTA Month During November, the RSGB used its Photo Friday feature on social media to highlight construction and practical skills. Photos included everything from Construction Clubs for newcomers to ground satellite repairs at university clubs. If these have left you feeling inspired and wanting to get creative, why not submit an entry to the Society's 2025 Construction Competition? There are six categories, including a new Outreach category that gives entrants the opportunity to create a project that can be reproduced in a school or public environment. Whether you are a seasoned constructor, used to building your own projects or a beginner looking to take your first steps in amateur radio construction, the RSGB would love to hear from you. Visit the RSGB website at rsgb.org/construction-competition  for full details of the competition and how to enter. For further inspiration, pick up a copy of the June Edition of RadCom and turn to page 36 to view last year's entries. The November 2024 issue of RadCom Basics is now available on the RSGB website for members to read. The publication is aimed at new licensees or anyone who enjoys reading about the fundamental principles behind the many facets of amateur radio. This issue includes part one of how to get on 40m with a small suburban garden, as well as articles on home construction and using repeaters. If you aren't one of the thousands of members who have done so already, you can subscribe to receive notifications about RadCom Basics via the RSGB Membership Portal. Log in and choose the “Manage preferences” tab. To read the latest edition go to rsgb.org/radcom-basics The RSGB would like to congratulate everyone who operated GB24YOTA last week. There was some brilliant activity on the air, including Wick High School Radio Club which had 12 student operators involved and inspired some to take their Foundation licence. If you missed talking to the group, you've got another chance to make a QSO with them today, Sunday the 8th of December. Taking over tomorrow, Monday the 9th of December is Hilderstone Radio Society, which will be operating between 9 am and 5 pm. Cray Valley Radio Society will host the callsign after 5 pm.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of December 2024. We had another week of high solar activity but limited geomagnetic disturbances. This meant that the upper HF bands were playing ball all week. The Kp index only exceeded four on one occasion, on the 30th of November when it hit 4.67, but otherwise, it has been low. With a solar flux index mainly in the 180s, this allowed the upper HF bands to shine. The maximum usable frequency or MUF over a 3,000km path has been consistently over 35MHz during daylight hours. The MUF over 100km has also been more than 14MHz around midday, making 20 metres almost a local band at times thanks to near vertical incidence skywave signals! If you have worked anyone in the UK on 20 metres let us know. An approaching active region just off the east limb of the sun was responsible for an M2.3 solar flare on the 4th of December, so perhaps increased solar activity is on the horizon. Next week NOAA predicts the week will start with the solar flux index starting in the 180s, perhaps then increasing to 200 as the week progresses. An increased geomagnetic disturbance is forecast for the period of the 10th to the 13th of December when the Kp index could increase to four. If this does come to fruition, we can expect MUFs to drop until the storming has passed. As always keep an eye on Propquest.co.uk for near-real-time MUF figures and solarham.com for Kp indices. And now the VHF and up propagation news from G3YLA and G4BAO. Meteor scatter is top of the list this coming week, with the big Geminids shower lasting throughout the month and peaking on Thursday the 14th of December. With a peak zenith hourly rate (ZHR) of 150 it's one of the most active and reliable of the annual showers. Other lesser meteor streams are also in play, so check the meteor scatter frequencies on 144, 50 and 70MHz where digimodes MSK144 and FSK441 will dominate activity. We have another period of primarily unsettled weather for the lead into this weekend, with deep lows bringing heavy rain, and perhaps some snow over northern hills. Watch out for very strong winds with potentially damaging gales in places. By the time many of you hear this on Sunday the 8th of December, we will be mid-way through the main event but hopefully, your antennas have survived. The better news is that the first half of the week is dominated by high pressure, so this brings a chance to repair antennas and get some Tropo time before a slow drift back to unsettled conditions in the second half of the week. For other modes, GigaHertz band rain and snow scatter will be worth considering especially over the weekend and again later in the week. Last Friday afternoon saw another big 50MHz F2 opening to North America, so continue to be vigilant if you're in the shack after lunch and the Kp index is below two. The solar conditions mean that there is still a chance of Aurora, although the Sun has been a bit quieter recently. Some days the f0Es trace on Propquest shows that weak Sporadic-E is still occurring. The Moon's declination is rising again and going positive on Monday. With falling path losses as we approach perigee on Thursday, it's a good week for EME. 144MHz sky noise is low all week. And that's all from the propagation team this week.

The RSGB Board is pleased to announce it has approved the appointment of Richard Horton, G4AOJ to the role of Legacy Committee Chair. The RSGB Legacy Fund, thanks to the generosity of donors, has significant financial resources available to encourage and develop amateur radio. The Legacy Committee, which is a sub-Committee of the RSGB Board, considers proposals for grants that can be awarded to projects from the RSGB Legacy Fund. The criteria and application form are available on the RSGB website at rsgb.org/legacy  If you have an interesting idea and would like to submit it for funding, you can contact the new Legacy Chair via legacy.chair@rsgb.org.uk SOS Radio Week is underway. It is an annual event that takes place throughout the month of May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Between them, members of these organisations save many lives who are in danger along and around the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI, and SOS Radio Week is being co-branded SOS Radio Week 200 for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coastwatch station, with the appropriate authorisation from the station manager. A commemorative certificate is available to all official stations that record their contacts on the website together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. To read more about the event visit sosradioweek.org.uk The next in the series of the popular 145 Alive events, to promote the use of 145MHz FM, is coming up on Saturday the 11th of May, from 1pm to 3pm. The event and the supporting Facebook Group was started by Tim, G5TM and from the start of 2024 has been organised by Mark, M0XIC and John, M0XJA. The last successful event took place in January this year, when over 30 nets operated simultaneously across England, Scotland, Wales and Northern and Southern Ireland. Over 900 QSOs took place, with many amateurs operating portable, mobile or from their club or home QTH. If you would like to take part, and find out more about the event and 145 Alive in general, then join the 145 Alive Facebook Group. Next weekend, the 11th and 12th, lots of amateur radio stations will be taking to the air as part of Mills on the Air Weekend 2024.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of May 2024 What a strange week we had. With the solar flux index in the 167 range, falling to 130, conditions should have been reasonable. But the Kp index hit 4, and even 5.33, on the evening of Friday the 26th of April, which meant propagation on Saturday the 27th was truly dire. Stations taking part in International Marconi Day on the 27th found the 40m band only open to long skip in the morning. This was due to the critical frequency being below 5MHz. The predicted MUF over a 3,000km path fluctuated between 15MHz and 19MHz for the whole day, which meant only 14MHz was open reliably. As a result, QSOs were hard to come by and many stations reported that it was slow going with virtually no signals from outside of Europe. So what happened? Well, it was a combination of factors. The increased Kp index, due to a fast solar wind, took its toll. And we are now moving to a summer ionosphere, where chemical changes make it harder to ionise. This will mean we should see MUFs dropping as the season progresses, at least during the day. Nighttime MUFs will be higher than in winter. So it may be that the glory days of 28MHz F2-layer propagation are on hold until Autumn, with only short-skip Sporadic-E on the 10m band to keep us entertained. F2-layer propagation is still available on the higher HF bands, but it may be patchy. International Marconi Day station GB0CMS in Caister, Norfolk, reported that its 20m signals were picked up by a reverse beacon network skimmer in Utah, despite not working anyone outside of Europe. Meanwhile, on the morning of the 2nd, Laurie, G3UML was quite surprised to work YJ0CA on Vanuatu on the 15m band using SSB. He also worked 3D2CCC on Conway Reef on the 20m band using CW, and JD1BMH in Japan on the 15m band, also using CW. Next week NOAA predicts the solar flux index will be in the 125 range, rising to 175 as the week progresses. Geomagnetic conditions are dependent on coronal mass ejections. We have had eight M-class solar flares in the past three days, and a Kp index of 5 on Thursday the 2nd, which doesn't bode well for next week. So, keep an eye on solarham.com for current conditions and look for the best HF propagation if the Kp index is low for a day or two. And now the VHF and up propagation news from G3YLA and G4BAO The weather pattern remains very unsettled for the whole period with areas of low pressure edging north across the UK from the continent. There will be a risk of thundery weather at times with locally heavy rainfall, which will be good for rain scatter on the Gigahertz bands. Tropo looks to be hard to find as we end the current week dominated by low-pressure systems, but there are signs of high pressure returning after mid-week, but only temporarily. This could produce some Tropo paths, especially across surrounding waters such as the Irish Sea, English Channel and North Sea. The nominal summer season of Sporadic-E propagation is upon us and, from May to early September, daily blogs will be provided on the Propquest.co.uk website highlighting the possible Sporadic-E links to the position of the jet streams shown on the upper air charts. It's well worthwhile getting into the habit of regularly checking the DX clusters and activity maps, since the early season is usually characterised by a complex jet stream pattern with multiple potential locations for Sporadic-E propagation.  Timewise, it eventually settles into a more traditional behaviour with activity often in two phases, one in the morning and the second in late afternoon, early evening. As you listen to this report, the Eta Aquariids meteor shower should be peaking. Unfortunately, the best viewing for the shower, which is part of the debris from Halley's comet, will be in the southern hemisphere. Nevertheless, this is expected to be one of the best showers this century. For those viewing the shower, a waning Moon means that light levels should be low, making for ideal visual sighting. For EME, the Moon will be waning all week with the new Moon around the 8th of May. The Moon will be rising in the sky throughout the week, with zero declination on the 5th of May and peaking at its highest in the sky on Saturday the 11th of May. The lowest additional path loss occurs today and tomorrow, the 5th and 6th, but high Sun noise, with the Moon close to the Sun at new Moon, occurs shortly afterwards. Later in the week, as the Sun 'leaves' the Moon behind, noise levels, at least on the higher bands will fall to around normal. And that's all from the propagation team this week.

Zetabytes? Petaflops? Gigahertz? Confusing terms for the ever-increasing capacity and speed of our computers.

  GB2RS News Sunday the 14th of April 2024 The news headlines: RSGB member interviewed by the BBC about the total solar eclipse Ofcom releases video about changes to UK amateur radio licensing World Amateur Radio Day is coming up On Monday the 8th of April, a total solar eclipse gripped North America as radio amateurs worldwide looked on to see its effect on the ionosphere. This included RSGB Propagation Committee associate member Gwyn Griffiths, G3ZIL, who was interviewed by BBC news on the topic. The article, which was shared across the world, looked at some of the scientific experiments that took place during the eclipse. You can read the article by searching for “The 4-minute window into the Sun's secrets” on BBC news. The RSGB thanks all the WSPR users who responded to Gwyn's call to action, got involved and shared their results on the RSGB social media channels.  Ofcom has released a video about changes to the UK amateur radio framework covering licensing and callsign changes. It also gives some insight into the forthcoming Phase 2 and Phase 3 of the changes for callsigns and special event stations. You can watch the video at tinyurl.com/ofcomvid World Amateur Radio Day is celebrated each year on the 18th of April. The theme for 2024 is “A Century of Connections: Celebrating 100 Years of Amateur Radio Innovation, Community and Advocacy.” The global event covers all of the IARU regions and runs from 0000UTC on Thursday the 18th of April to 0000UTC on Friday the 19th of April. All radio amateurs are invited to take to the airwaves to show their skills and capabilities to the public. You can read more about the event at tinyurl.com/iaruward During May, the RSGB's Photo Friday feature on social media will highlight radio amateurs who are taking advantage of the new licence conditions. You could be an individual who is discovering different things to enjoy with the new power levels, or who is encouraging friends and family to get on the air under your supervision. You could be a club involved in special events and outreach to the public. In whatever way you're making the most of the new licence conditions, the RSGB wants to hear from you! Send a photo and a short description to comms@rsgb.org.uk and the Society will share as many stories as possible. On the 11th of April, BBC Radio 4 Feedback presenter Andrea Catherwood looked at why the Long Wave frequency is being shut down by the BBC. She interviewed RSGB President John McCullagh, GI4BWM, and in the final programme, a brief clip was used in which John gave his opinion on the possible impact for some listeners. You can listen to the Feedback show on BBC Sounds, by searching for “Feedback and Long Wave” on the BBC website. The feature starts at 19 minutes and 55 seconds, with the RSGB President featuring at 22 minutes and 18 seconds. This year Dennis, G7AGZ is running special event station GB0CHC again in support of Cornwall Hospice Care. This is Dennis' 33rd year of fundraising for the charity. The station will be active until the end of April on all bands from 80m to 70cm using SSB, FM and DMR. If you would like to support the cause, search for GB0CHC on the justgiving.com  website The Cornish Radio Amateur Club has re-launched its sought-after Cornish Award Certificate.

Using All modes on the 4m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of April 2024 The Sun is still looking a little bare, but the solar flux index has climbed back to 131, as of Thursday the 11th, with four active regions. The promise is that things will improve, especially as we will soon see the return of active region 3615, which was the source of numerous M-class and one X-class flare on its last rotation. Things have been a little sparse on the higher HF bands, with only FT8 being audible or visible on the 10m band at times. Having said that there has been some good FT8 DX to be worked on the 10m band, including Angola, Malawi, China, Japan, Taiwan and the Solomon Islands. During the recent solar eclipse event there were also a lot of US stations on the 10m band using WSPR. These included Bob, K6XX in Santa Cruz, California, who was copiable in the UK at around 1850UTC. This just shows how effective WSPR is as a mode on an otherwise quiet band. There have been some early signs of Sporadic-E on the 10m band using digital modes, including some brief openings to Scotland from eastern UK. We can expect these to improve as we head towards May. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range with a maximum Kp index of three. If this is correct it means that HF conditions will be roughly the same as last week. And now the VHF and up propagation news from G3YLA and G4BAO The weather patterns are showing signs of change after being stuck for quite some time, and the main beneficiary will be VHF operators seeing a chance of Tropo returning to the bands.  The initial unsettled weather over the UK, with high pressure fixed over the continent, will take us through to the middle of the coming week. Thereafter, a high will develop to the southwest of Britain midweek and drift northeast across the country, although some models take the high on a more southerly track. In either event, there should be some useful Tropo in the south and possibly northern areas too. This may be limited to southwestern areas for Tuesday's 23cm UK Activity Contest, but will hopefully be more supportive of the 4m UK Activity Contest on Thursday. Meteor scatter is worth a look next week since we are approaching the 21st and 22nd of April peak of the Lyrids shower at the end of next weekend. The quieter solar conditions have taken aurora down the table, but it's still good practice to watch out for if the Kp index goes above five. Gigahertz-band rain scatter certainly drops down the league table next week as high pressure probably takes over. As we said earlier, the next big thing is the start of the 2024 Sporadic-E season, which slowly comes to life during April for the 10 and 6m bands, especially on digital modes, whereas the real shift up in gear often comes during May. As mentioned last week, it's worth updating your list of beacons in your rig's memory while it's still quiet. For EME operators, Moon declination is at maximum this weekend, ending the 14th, so there will be long Moon windows. We are past perigee, so path losses are rising again. 144MHz sky noise is moderate this weekend then low for the rest of the week. And that's all from the propagation team this week.

Heute treffen zwei bemerkenswerte Ereignisse aufeinander: Einerseits halten wir im Nerdfunk wie jeden letzten Dienstag im Monat Kummerbox live ab. Andererseits ist Halloween. Das ist ein invasiver Brauch, von dem zu Matthias' Jugendzeiten noch niemand gehört hatte, der aber mit Umweg über die Vereinigten Staaten und deren kulturelle Erzeugnisse auch bei uns eingewandert ist. Und ja, wir haben auf Computerprobleme gehofft, bei denen das eine zum anderen kommt: Auf heulende Festplatten, quietschende Tastaturen und KIs, die «Trick or Treat» rufen, statt uns brav unsere Fragen zu beantworten. Leider wird nichts daraus. In Ermangelung von gruseligen, kürbismässigen oder Süssigkeiten-lastigen Fragen müssen wir unser ganz normales Pensum abarbeiten. Oder doch? Wenn wir Erikas Frage genau ansehen, könnten wir uns vielleicht vorstellen, wie ein kleines Phantom in den Google-Drive-Servern hockt. Jedenfalls möchte sie wissen, warum es ihr unmöglich ist, Fotos per Link zu verschicken. Journalisten-Kollege Felix hält sein Telefon für verhext, weil es keine Interviews aufzeichnen will. Magnus fragt, warum sein E-Book-Reader nicht mit dem Mac zusammenkommen will. Und ja: Pauls Inbox ist von Spam besessen!

GB2RS News Sunday the 10th of September 2023 The news headlines: RSGB 2023 Convention RSGB 2023 outreach and buildathons National Coding Week     The RSGB 2023 Convention will be held this year from the 13th to the 15th of October. It is an action-packed weekend of amateur radio and includes the AMSAT-UK Colloquium which will be held during the Convention again. You can chat to the Special Interest Groups and RSGB Committees over a coffee, browse the latest amateur radio equipment and maybe even win a great prize if you buy a ticket in the DXpedition Fund raffle. There will also be two interesting forums on Saturday run in partnership with ICQPodcast. For the first time, the Convention will also have a clear focus on outreach and practical activities as the RSGB provides opportunities for individuals and clubs to ‘have a go' and be inspired to try new things in their local areas. The draft programme will be available in the October RadCom but is also available now on the RSGB website to give you an idea of the fantastic range of talks that will be happening over the weekend. Find out more and take advantage of the early-bird booking price which is available until the 14th of September – go to rsgb.org/convention As part of the RSGB's commitment to the growth of amateur radio, Regional Representative David De La Haye, M0MDB will be giving a presentation at the RSGB Convention in which he will explain more about the Regional Team and how its members can support you to do amateur radio outreach in your local area. A particular focus will be on organising the ever-popular buildathon events. Once you've picked up some tips, you can then have a go at building one of a range of kits provided by Kanga Products. The RSGB Convention buildathon is a drop-in event on Saturday the 14th of October which runs from 10.30am to 5pm. You can also confirm your preferred time by pre-booking a slot for a deposit of £5, which is refundable against the cost of the kit you choose to build. Pre-booked time slots will be allocated as first-come, first-served, so make sure to book now! For full details and to book your slot, visit the RSGB website at rsgb.org/buildathon National Coding Week runs from the 18th of September, but the RSGB is dedicating the whole of September to a focus on amateur radio and coding. There is a range of activity sheets on the RSGB website and we know of schools and amateur radio clubs that are getting involved. Whether you'd like to try the BBC:Microbit, have a go at Node RED or find out more about GNU Radio, this is a great way to try something new, extend your skills, or share your knowledge with your local club, school or community group. If you'd like some support or advice, contact RSGB volunteer John Hislop, G7OHO via g7oho@rsgb.org.uk, and if you're planning an event let the RSGB know – email comms@rsgb.org.uk so the Society can share your stories and photos to inspire others!

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of September 2023 The propagation team was caught out last week by two coronal mass ejections, or CMEs, that came off the edge of the Sun. The arrival of those CMEs on the 3rd of September eventually pushed the Kp index to 5.67. In its report, Spaceweather.com said that it was possible that a CME arrived on the 2nd of September, but its weak impact was masked by a chaotic stream of solar wind already blowing around Earth at the time. At this time of year, even weak CMEs can do a good job of sparking auroras as a result of the Russell-McPherron effect, which boosts geomagnetic activity around the equinoxes. So much for saying that we could expect quiet geomagnetic conditions last week! The Solar Flux Index declined to 131 but has since recovered to reach 147 on Thursday the 7th, with eight active regions visible. We had a number of M-class solar flares last week, but nothing too damaging. With the Kp index back to one on the 7th, we saw daytime MUFs rising again, heading above 24.9MHz over a 3,000km path. There were lots of Chinese and Japanese stations on 21MHz FT8 around 1100UTC on Thursday. And up on 12m FT8, even more of the same. DX stations included Thomas, KH0/KC0W on the Mariana Islands in the Pacific. While the 10m band was just about open as well, it offered slim pickings compared with the 12m band. Next week NOAA predicts that the Solar Flux Index will increase over the week to hit perhaps 155 by next weekend. Geomagnetic conditions remain variable with a Kp index of three or four forecast for the 12th to the 16th. This weekend the geomagnetic forecast is that it will be quiet although, with so many sunspots visible at the moment, it wouldn't take much for a CME to disrupt things. As always, keep an eye on solarham.net for near real-time updates. And now the VHF and up propagation news The RSGB 144MHz Trophy produced good DX on 2m into Poland and Sweden, so we guess that Tropo performed for us this week. This spell of hot sunny weather, due to high pressure, does mean Tropo was the mode of choice for the end of this current week, ending today the 10th, especially across the North Sea. However, unsettled weather is gradually encroaching from the west, introducing some thundery rain into western areas, and this will spread east. Although the Tropo will cease, Gigahertz bands rain scatter is a likely replacement although very isolated rather than the widespread nature of a good Tropo event. It should be noted that next week is not fully determined by all models with quite a spread of outcomes. Either way, it's Tropo or rain scatter for most areas next week. It's always possible that meteor scatter and aurora could show during this period. The early morning, around dawn, is usually the best time to look for random meteor scatter activity in the absence of any major meteor showers. For aurora, it's best to follow the solar data from spaceweather.com to pick up early alerts and an increasing Kp index. For EME stations, Moon declination is at its highest this weekend but with apogee, the Moon's furthest point from Earth, next Tuesday, path losses are high. 144MHz sky noise is low for most of the week except for Thursday and Friday when the Moon and Sun are very close, meaning high solar noise in the beamwidth of antennas.    And that's all from the propagation team this week.

Welcome back Data Center Therapy fans!  We have a special treat on this podcast as IVOXY's own Kris Lamet returns to the virtual DCT studios, this time employed at NetApp as their Technical Partner Manager for the Pacific Northwest and Western Canada. Kris and your two intrepid hosts, Matt “2.4 Gigahertz?  Sure Does!” Yette and Matt “Deadbolt This!” Cozzolino crack a couple of frosty ones and muse about the amazing longevity and adaptability of NetApp, the challenges of using the cloud either for DR or for hybrid datacenter scaling, and the newest home automation projects they're all working on. You'll also learn in this episode: Which technologies NetApp themselves pioneered that are still in widespread use by all storage vendors to this day. How many unique products NetApp have in their portfolio, and which new acquisitions they've made have been relevant to the cloud-first adopters. What challenges in home automation arise with WiFi versus Z-Wave devices and why RoomAssistant and HomeAssistant have tortured Matt Yette most recently. When listening, you're in for some storage and cloud talk for sure, but you'll also be a party to some good old-fashioned IVOXY Squad camaraderie and home gadget talk, so there's something for everybody.  Please be sure to like, share and subscribe as always, and stay connected, stay secure, stay cloud-enabled, and stay tuned for the next great episode of Data Center Therapy!  Thanks for listening!

Pietsch hat etwas Neues gefunden, was seiner Meinung nach abgeschafft werden sollte. Es hat doch angeblich sowieso niemand genug davon. Doch stimmt das wirklich? Während er dabei über das angehende Eisenbahnwesen im 19. Jahrhundert referiert, nähert sich Stephan in seinen Ausführungen schon bald dem absoluten Nullpunkt, da er seine innere Atomuhr überlisten möchte. Bleibt nur noch offen, ob 1,21 Gigawatt für kommerzielle Zeitreisen im rechtssicheren Raum ausreichen und wie lange ein Helene Fischer Konzert bei -30°C wirklich dauert. Halbwissen² - man muss nur vierdimensional denken!

What people may not know is that the current roll out of the 5G telecommunications network, is a massive undertaking being coordinated around the world and pushed by the corporate elite. Engulfing the entire planet via 100 thousand satellites, millions of telecommunication towers, small cells and billions of 5G connected devices flooding the world with invisible electro smog pollution in the form of electromagnetic radiation. The 5G rollout will increase man-made electromagnetic radiation at unprecedented levels with little to no concern for the safety and wellbeing of the humans who will be exposed to it. In Australia concerned citizens have formed a political Party called the ‘NO 5G Party' - that will be in every state across Australia.  Ray is the president of it at the moment and they have a thousand members and at the next General Election they will be running candidates in every State, specifically on electro magnetic radiation issues. Also, its a Party to educate people that there has been a unprecedented upgrading and building of Mobile telephone towers and ‘small cells' for 5G across Australia - saying it has been happening here in NZ and that most people have no idea that this is happening as we read to this. That in Australia all the Telcos are eagerly waiting the Australian Govt's 5G 26 Gigahertz frequency sale. We know that the 26 Gigahertz band is a frequency that is billions of times higher than the frequencies that we have been exposed up to now. Thus is very problematic health wise. The will come to NZ too. This will mean that 26 Gigahertz Non ionising electro magnetic radiation penetrates our bodies. 26 Gigahertz Non ionising electro magnetic radiation penetrates our bodies. Through both skin and tissue at 26 billion pulses per second.  Compared with only 50 pulses per second as found in the 50 hertz frequency - as irradiated by many of the electrical appliances around the home. Vodafone in this interview admits that the radio wave penetrates the skin - listen. And Ray says that he is sure that people do not consent to that. Some frequencies penetrate the skin to a depth of 8.1 millimetres.  ARPANSA.gov.au - the Australian Radiation Protection and Nuclear Safety Agency  - listen toabout Dr Ken Karipidis - is an expert on jopw tradition affects the human body. What this has come os that humanity is being assaulted   These wireless frequencies are an assault on the human body.  This is where the battle lines are. The Crimes Act in NZ 1961 - Under Section 2 - gives an interpretation - An assault means the act of intentionally applying or attempting to apply force to the person of another - directly or indirectly  or threatening by any act or gesture to apply such force to the person of another. Electro magnetic radiation is a force and if you do not consent to it - then who ever is touching you or penetrating you - must stop. Otherwise it is an offence under the Crimes Act 1961. Listen to this interview: Of Dr Bruce Hocking's research with children in Australia in 1996   - irradiated from 3 broadcast towers in Sydney NSW.  LISTEN - he found that there was a 60%  increase in childhood deaths from childhood lymphatic leukaemia in the immediate vicinity of those towers. His was a time when the frequencies were far lower than todays frequencies. Listen to 19 children dying with lymphatic leukaemia in Rome Italy when the Italian supreme court found them guilty due to them living in to closer proximity to the Vatican radio station. https://www.abc.net.au/news/2005-05-10/vatican-radio-officials-convicted-in-electro-smog/1567232 An Italian court has found a Roman Catholic cardinal and a director of Vatican Radio guilty of polluting the atmosphere with powerful electromagnetic waves from a radio transmission station. Note that today - Leukaemia is now the most common cancer in Australian Children  Mobile phones were introduce in 1981 and the sharp increase in childhood leukaemia is no coincidence. Have a listen. Ray also mentions that a sleeping virus that is dormant in a human body can be reactivated when exposed to non ionising radiation .  This is important information. Healthy Heavens Trust in Australia https://healthyheavenstrust.org   This is about regarding Satellites in low geo stationary orbit. Ray's team have filed against Elon Musk and other satellite providers in exposing Australians to electromagnetic radiation from satellites - because they do not know what degree of exposure Australians will be exposed too. Bodily Affects. Synapses and nerves are affected as well as cardiac muscles. There appears to be no cure for exposure to non ionising radiation. Ray says that the new wireless towers are pumping out very powerful radiation - have a listen. Stopping this radiation in Australia is schools is becoming very concerning in schools - a duty of care issue - if wifi is throughout schools - they are technically assaulting the children.  Thousands of Satellites in Low Earth Orbit. 100,000 SpaceX lanced satellites will be up above our head in the next 5 years - plus high altitude platform stations. (see previous interview of Ray) mostly launched from Australian soil - at Wyndham launched into the stratosphere - they are like a giant drones that can stay up there for months. Get this! - Each Orbiting Platform is going to be the equivalent to 1,800 base stations, each … they will circulate in a 200 kilometres circumference and they will have a seamless connection to earth base stations. They are designed to connect to high altitude satellites as well as our basic telephone towers, There is another  reason why this is all happening - your mobile phone will be able to be charged from these flying platforms and you will never have to plug your mobile phone into the wall to get it charged - ever again . Note, there is no mention of the health effects from all the electrical charges and frequencies that we find ourselves immersed in.  No health affects have been factored in. The flying wing will via wireless electricity charge your phone from then on. Ray further says that it's planned that all your appliances in your home will be powered this way -  TV - radio, toaster you name it.  Even your electric car is supposedly planned to be automatically charged (what a fantasy). Wireless power transfer has been around for a long time. Nikola Tesla was planning to do this over a hundred years ago and had completed the preliminary testing and it worked. But, in those days, there was no way to ‘monitor it' and ‘charge for it'. So JB Morgan, Tesla's financier not wanting people to have free transport and pulled the plug on Tesla. The battery powered Tesla cars of today - are a compromise. Listen to Ray, mention that in Australia they have the worlds largest database on health affects. That the scientific consensus states that there is ‘wireless' data that states 68% of all studies - show adverse health affects. Only 24% of all studies show no effect. I did not ask him about the other 8%  Even high voltage powerlines - have affected the birthing rate of cows and Ray on behalf of some pastoralists - have taken the Power companies to court and won - Have a listen. Tell the Telcos that you do not consent to being touched by wireless radiation - and then communicate with these and other Telcos about it - and to stop. www. no5gparty.org.au OTHER Subjects Covered.

Todos que utilizam internet pelo smartphone ou outro dispositivo portátil estão acostumados com nomenclaturas como 3G e 4G. O que poucos sabem é que esses “gês” remetem às frequências de ondas utilizadas na transmissão de dados. O 3G, por exemplo, trabalha entre 850 megahertz (MHz) e 2.100 megahertz, enquanto o 4G funciona na faixa de 2,5 gigahertz (GHz). Mas o avanço científico não para e os equipamentos mais modernos atuam em frequências muito acima dessas.  Pensando nisso, foi inaugurado, na Escola Politécnica (Poli) da USP, o Centro de Ondas Milimétricas (mmW). O espaço permite que empresas e grupos de pesquisa desenvolvam equipamentos, circuitos e dispositivos de telecomunicação projetados para operar em frequências de até 110 GHz. Essas faixas permitem, por exemplo, o desenvolvimento de tecnologias 5G. Como explica Ariana Lacorte Serrano, professora da Poli e coordenadora do projeto, o objetivo do Centro mmW não é desenvolver por conta própria esse tipo de equipamento, mas auxiliar os interessados a realizar esse processo, disponibilizando meios para isso: “Queremos dar acesso às empresas que realmente precisam chegar num produto final (que não é o nosso caso), para que elas consigam fazer as medidas que elas precisam, os testes que elas precisam ou eventuais desenvolvimentos. Estou falando eventuais, porque no Brasil não se costuma ter um desenvolvimento enorme em tecnologia”. Dentre os equipamentos que o novo centro permite desenvolver, se destacam aqueles que operam em frequências 5G. O professor Cristiano Magalhães Panazio, também da Escola Politécnica da USP, comenta quais são os diferenciais desse tipo de dispositivo, capazes de fazer brilhar os olhos das maiores potências do mundo: “A questão é basicamente taxa. Então, se você estiver com uma qualidade boa de sinal, você vai conseguir transmitir com taxas muito mais altas do que são conseguidas hoje em dia com sistemas 4G, por exemplo”, explica o especialista. Em termos práticos, essas melhorias devem resultar em maior velocidade de download e upload, assim como coberturas mais amplas e conexões mais estáveis.

Heute erkläre ich dir was eigentlich ein Gigahertz ist. Viel Spaß! Dein Christoph

Wir feiern das erste kleine Jubiläum - die zehnte Folge! - Mit einem echten Innvationsthema. Es geht um Quantencomputer! Wir gehen mit euch an den Rand der Prozessortechnologie und an den Rand unseres Wissens, um einen Blick in die Zukunft zu werfen. * Los geht es mit einem kurzen Abholer wie Chips heute funktionieren * dann startet die wilde Reise von Albert Einstein zu Konrad Zuse, von Gigahertz zu Qubits. * Nach ganz viel Facts gehts auch darum, wer wohl die ersten Quantencomputer haben wird... und was wir normale Menschen eigentlich damit machen, dass es jetzt Quantencomputer gibt.

Für viele Probleme fehlt immer noch die Rechenpower. Können Quantencomputer die Lösung sein? Statt Terabytes und Gigahertz und bieten sie heute gerade mal 50 Qubits – aber das könnte täuschen. Erste Quantenrechner stehen für jedermann bereit. Bis zur „quantum supremacy“ gibt es aber noch viele technische Hürden.

Physicist Spencer Klein and Electrics Engineer Thorsten Stezelberger, both at Lawrenc Berkeley National Lab, describe the Neutrino Astronomical project IceCube, which was recently completed in Antarctica. They also go on to discuss proposed project Arianna.TranscriptsSpeaker 1: Spectrum's next [inaudible]. Welcome to spectrum [00:00:30] the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 2: Good afternoon. I'm Brad Swift, the host of today's show, Rick Karnofsky and I interview Spencer Klein and Torsten Stessel Berger about the neutrino astronomy project. Ice Cube. Spencer Klein is a senior scientist and group leader at Lawrence Berkeley National Lab. [00:01:00] He's a member of the ice cube research team and the Ariana planning group. Thorsten Stetso Berger is an electronics engineer at Lawrence Berkeley National Lab. He too is part of the ice cube project and the Ariana team. They join us today to talk about the ice cube project and how it is helping to better define neutrinos. Spencer Klein and Thorsten setser Berger. Welcome to spectrum. Speaker 3: Thank you. Thank you. Can you talk to us a little bit about neutrinos? [00:01:30] Well, neutrinos are subatomic particles which are notable because they barely interact at all. In fact, most of them can go through the earth without interacting. This makes them an interesting subject for astrophysics because you can use them to probe places like the interior of stars where otherwise nothing else can get out and are most of them neutrinos from those sources. There's a wide range of neutrino energies that are studied. Some of the lowest energy neutrinos are solar neutrinos which [00:02:00] come from the interior of our sun. As you move up to higher energies, they come from different sources. We think a lot of the more energetic ones come from supernovas, which is when stars explode, they will produce an initial burst of neutrinos of moderate energy and then over the next thousand years or so, they will produce higher energy neutrinos as ejected spans, producing a cloud filled with shock fronts and you're particularly interested in those high energy. Speaker 3: Yes, ice cube is designed to study those neutrinos and also [00:02:30] neutrinos from even more energetic neutrinos where we don't really know where they come from. There are two theories. One is that they come from objects called active Galactic Nuclei. These are galaxies which have a super massive black hole at their center and they're rejecting a jet of particles perpendicular, more along their axis. And this jet is believed to also be a site to accelerate protons and other cosmic rays to very high energies. The other possible source of ultra energy neutrinos [00:03:00] are gamma ray bursts, which are when two black holes collide or a black hole collides with a neutron star. And if the neutrinos don't interact or interact so rarely and weekly with matter, how do we actually detect them? Well, the simple answer is you need a very large detector. Ice Cube is one cubic kilometer in volume and that's big enough that we think we should be able to detect neutrinos from these astrophysical sources. Speaker 3: The other project we work on, Ariana is even bigger. It's [00:03:30] proposed, but it's proposed to have about a hundred cubic kilometers of volume. And so you have an enormous detector to detect a few events and once you detect them, how can you tell where they came from? Well, with ice cube we can get the incoming direction of the neutrinos to within about a degree. So what we do is we look for neutrinos. Most of what we see out of these background atmospheric neutrinos which are produced when cosmic rays interact in the earth's atmosphere. But on top [00:04:00] of that we look for a cluster of neutrinos coming from a specific direction. That would be a clear sign of a neutrino source, which would be, you know, and then we can look in that direction and see what interesting sources lie. That way we can also look for extremely energetic neutrinos which are unlikely to be these atmospheric neutrinos. Speaker 3: And how is it that you measure that energy? What happens is a neutrino will come in and occasionally interact in the Antarctic. Ice should mention that ice cube is located at the South Pole where [00:04:30] there's 28 hundreds of meters of ice on top of the rock below. Occasionally in Neutrino will come in and interact in the ice and if it's something called a type of neutrino called the [inaudible] Neutrino, most of its energy will go into a subatomic particle called the Meuron. Meuron is interesting because it's electrically charged. As it goes through the ice, it will give off light, something we call Toronto radiation. So we've instrumented this cubic kilometer of ice with over 5,000 optical [00:05:00] modules, which are basically optical sensors. And so we record the amount and arrival times of the light at these optical sensors. And from that we can determine the neutrino direction to about within a degree. Speaker 3: And we can also get an estimate of the energy. Um, essentially is the on is more energetic. It will also produce other electrically charged particles as it travels. Those will give off more light. And so the light output is proportional to the neutrino energy. So you're taking an advantage of the fact that there's [00:05:30] a lot of ice in Antarctica and also that it's very big. Are there other reasons to do it at the South Pole? Well, the other critical component about the ice is that it has to be very clear, shouldn't scatter light and it shouldn't absorb light. And in fact the light can travel up to 200 meters through the ice before being absorbed. This is important because that means we can have a relatively sparse array. You know, we have only 5,000 sensors spread over a cubic kilometer. That's only if the light can travel long distances through the ice. [00:06:00] And do you have to take into account that the ice in the Antarctic is not perfectly clean? Yes. When we reconstruct the neutrino directions, we use this sophisticated maximum likelihood fitter. Essentially we try all sorts of different Milan directions and see which one is the most likely. And that takes into account the optical properties of the ace and includes how they vary with depth. There are some dust layers in the ice where the absorption length is much shorter and some places, [00:06:30] well most of the ice where it's much better. Speaker 4: Our guests on spectrum today are Spencer Klein and Thorsten Stetson Burger from Lawrence Berkeley national lab. They are part of a physics project named Ice Cube. In the next segment they talk about working at the South Pole. This is KALX Berkeley. Speaker 3: Can you compare the two experiments, both ice Cuban on a little bit? Well, ice cube is designed [00:07:00] for sort of moderate energy neutrinos, but for the really energetic neutrinos are, they are rare enough so that a one cubic kilometer detector just isn't big enough. And so for that you need something bigger and it's hard to imagine how you could scale the optical techniques that ice cube uses to larger detectors. So that's why we looked for a new technique in it. Here I should say we, the royal, we either many people, many places in the world looking at different versions. And so what we've chosen is looking [00:07:30] for radio [inaudible] off the mission. You know, we have this interaction in the ice. Some of the time. If it's an electron Neutrino, it produces a compact shower of particles. That shower will have more negatively charged particles than positively charged. Speaker 3: And so it will emit radio waves, you know, at frequencies up to about a Gigahertz coherently, which means that the radio emission strength depends on the square of the neutrino energies. So when you go to very high neutrino energies, this is a preferred technique. Radio waves can [00:08:00] travel between 300 meters and a kilometer in the ice, which means you can get by with a much sparser array. So you can instrument a hundred cubic kilometers with a reasonable number of detectors. When Ariane is developed, it will get to access higher energies. Will it still didn't detect some of the moderately high energies that ice cube is currently reaching? No, and there's no overlap because of the coherence and just not sensitive. I mean, ice cube will occasionally see these much higher energy neutrinos, [00:08:30] but it's just not big enough to see very many of them. Uh, you commented on, or you mentioned the size of the collaboration. Speaker 3: Can you sort of speak about how big these projects are? Sure. Ice Cube has got about 250 scientists in it from the u s Europe, Barbados, Japan, and New Zealand. Oh yeah. And plus one person from Australia now. And that's a well established, you know, it's a large experiment. Arianna is just getting going. It's got, I'll say less than a dozen [00:09:00] people in it. Mostly from UC Irvine and some involvement from LDL. How many years have you had experience with your sensors in the field then? That's kind of a complicated question and that the idea of doing neutrino astronomy in the Antarctic ice has been around for more than 20 years. The first efforts to actually put sensors in the ice, we're in the early 1990s these used very simple sensors. We just had a photo multiplier tube, essentially a very sensitive [00:09:30] optical detector, and they sent their signals to the surface. There are no complicated electronics in the ice. Speaker 3: The first Amanda effort in fact failed because the sensors were near the surface where the light was scattering very rapidly. Turns out the upper kilometer of ice is filled with little air bubbles, but then as you get down in depth, there's enough pressure to squeeze these bubbles out of existence. And so you go from very cloudy ice like what you see if you look in the center of an ice cube and then you go deeper [00:10:00] and you end up with this incredibly clear ice. So the first efforts were in this cloudy ice. Then in the second half of the 1990s Amanda was deployed in the deep highs. This is much smaller than ice cube in many respects. The predecessor, of course, the problem with Amanda was this transmission to the surface. It worked but it was very, very touchy and it wasn't something you could scale to the ice cube size. So one where people got together and came up with these digital optical modules where all of the digitizing electronics [00:10:30] is actually in the module. We also made a lot of other changes and improvements to come up with a detector that would be really robust and then we deployed the first ice cube string in 2005 and continued and then the last string was deployed at the end of 2010 Speaker 5: so basically from the scientific point or engineering point of view, we're learning about the detector. We got data from the first strain. It was not very useful for take neutrino science but you can learn to understand [00:11:00] the detector, learn how the electronics behaves, if there is a problem, change code to get different data. Speaker 3: When we did see some new is in that run and there's this one beautiful event where we saw this [inaudible] from a neutrino just moving straight up the string. I think it hit 51 out of the 60 optical sensors. So we're basically tracking it for 800 meters. It was just a beautiful that Speaker 5: what is the lifelight down there? The food, the day to day, [00:11:30] we've never been there in the winter time, so I can only talk about a summer and in the summer you're there for something specific like drilling or deploying a, so to summertime keeps you pretty busy and you do your stuff and then afterwards you hang out a little bit to wind down. And sometimes with some folks playing pool or ping pong or watching movies or just reading something and then time [00:12:00] again for the sleep or sleeping. And the next day for drawing for example, we had three shifts. And so that kept you pretty, pretty busy. One season when I was thrilling there I was on what we call the graveyard shift. Starting from 11 to I think eight in the morning. I saw and yeah, it was daylight. You don't notice it except you always get dinner for breakfast and scrambled eggs and potatoes for dinner. Speaker 3: The new station at the South Pole is really very nice and I would [00:12:30] say quite comfortable, good recreational facilities. I mean, and I would say the food was excellent, really quite impressive and you get to hang out with a bunch of international scientists that are down there. How collegial isn't, it Speaker 5: depends a little bit on the work. Like when I was rolling on night shift, we mostly got to hang out with people running the station. That was fairly collegial. Speaker 3: There's actually not very many scientists at the South Pole. In the summer there were about 250 [00:13:00] people there and maybe 20 of them were scientists. Most of them were people dealing with logistics. These are people, you know, heavy equipment operators. Fuel Lees would get the fuel off of the plane, cooks people, and even then can building the station wasn't quite done yet. The drillers will lodge wide variety of occupations but not all that many scientists. How close are the experiments to the station? Speaker 5: They are quite a few experiments [00:13:30] based in the station. Ice Cube is a kilometer away about probably Speaker 3: Lamotta and a half to the, to the ice cube lab, which is where the surface electronics is located. Speaker 5: So it's pretty close walking distance called walk. But it depends. I mean I don't mind the calls or it was a nice walk but they have like ice cube, uh, drilling. We are like lunch break also. It's [00:14:00] a little bit far to walk kilometer out or even throughout depending where you drill. So we had a car to drive back and forth to the station to eat lunch. Otherwise you are out for too long. Speaker 3: Yeah, they give you a really good equipment and so it's amazing how plaza you can be about walking around when it's 40 below, outside. Speaker 5: Especially if you do physical work outside as part of drilling also. It's amazing how much of that cold weather Ikea you actually take off because you just [00:14:30] do staff and you warm up. Speaker 4: [inaudible] you are listening to spectrum on KALX Berkeley coming up, our guests, Spencer Klein and Torsten Stotzel Burger detail, the ice cube data analysis process, Speaker 3: the ongoing maintenance of Ice Cube Sarah Plan for its lifetime Speaker 5: for the stuff [00:15:00] in the eyes, it's really hard to replace that. You cannot easily drill down and take them out. They are plans, uh, to keep the surface electronics, especially the computers update them as lower power hardware becomes available. Otherwise I'm not aware of preventive maintenance. You could do with like on a car. Yeah. Speaker 3: I have to say the engineers did a great job on ice cube. About 98% of the optical modules are working. Most of the failures were infant [00:15:30] mortality. They did not survive the deployment when we've only had a handful of optical modules fail after deployment and all the evidence is we'll be able to keep running it as long as it's interesting. And is there a point in which it's no longer interesting in terms of how many sensors are still active? I think we'll reach the point where the data is less interesting before we run out of sensors now. Okay. You know, we might be losing one or two sensors a year. In fact, we're still at the point where [00:16:00] due to various software improvements, including in the firmware and the optical modules, each year's run has more sensors than the previous years. Even if we only had 90% of them working, that would be plenty. Speaker 3: And you know, that's probably a hundred years from now. What do we have guests on to speak about the LHC at certain they were talking about the gigantic amounts of data that they generate and how surprisingly long it takes for scientists to analyze that data to actually get a hold [00:16:30] of data from the detector. And you're generating very large amounts of data. And furthermore, it's in Antarctica. So how much turnaround time is there? Well, the Antarctica doesn't add very much time. We typically get data in the north within a few days or a week after it's taken. There is a bit of a lag and try and take this time to understand how to analyze the data. For example, now we're working on, for the most part, the data that was taken in 2010 and [00:17:00] you know, hope to have that out soon probably for summer conferences. But understanding how to best analyze the data is not trivial. For example, this measurement of the mule on energies, very dependent on a lot of assumptions about the ice and so we have ways to do it now, but we're far from the optimal method Speaker 5: and keep in mind that detector built, it's just finished. So before you always added in a little bit more. So each year the data looked different because you've got more sensors in the data. Speaker 3: [00:17:30] Let's say for things where turnaround is important. For example, dimension, these gamma ray bursts, there's where this happens when a bunch of satellites see a burst of x-rays or gamma rays coming from somewhere in the sky. They can tell us when it happened and give us an estimate of the direction. We can have an and I would say not quite real time, but you know that we could have turned around if a couple of weeks. We also measure the rates in each of the detectors. This is the way to look for low energy neutrinos from a [00:18:00] supernova that is essentially done in real time. If the detector sees an increase, then somebody will get an email alert essentially immediately. If we got one that looked like a Supernova, we could turn that around very quickly. So are the algorithms that you're using for this longer term analysis improving? Speaker 3: Yes. They're much more sophisticated than they were two years ago. I'd say we're gradually approaching and I'm ask some Todrick set of algorithm, but we're still quite a ways [00:18:30] to go. We're still learning a lot of things. You know, this is very different from any other experiment that's been done. Normally experiments if the LHC, if they are tracking a charged particle, they measure points along the track. In our case, the light is admitted at the trend off angle. About 41 degrees. So the data points we see are anywhere from a few meters to a hundred meters from the track. And because of the scattering of light, it's a not so obvious how to find [00:19:00] the optimum track and it's, you know, it's very dependent on a lot of assumptions and we're still working on that. And we have methods that work well. As I said, you know, we can get an angular resolution of better than a degree in some cases, but there's still probably some room to be gotten there. Speaker 5: And then also, I mean I'm not involved in the science, but I hear people have new ideas how to look at a data. So that's still evolving too. Speaker 3: Yeah. Like you know, one analysis that people are working on, but we don't have yet would [00:19:30] be a speculative search where you're looking for a pair of event, a pair of neo-cons going upward through the detector in the same direction at the same time, which would quite possibly be a signal of some sort of new physics. And it's certainly an interesting typology to look for, but we're not there yet. And are there different teams looking at the same data to try to find different results and broaden the search so to speak? Uh, yes. We have seven or eight different physics working [00:20:00] groups in each of those groups is concentrating on a different type of physics or a different class of physics. For example, one group is looking for point sources, you know, hotspots in the sky. Second Group is looking at atmospheric and diffuse neutrinos trying to measure the energy spectrum of the neutrinos. Speaker 3: We do see both the atmospheric and also looking for an additional component. There's a group doing cosmic ray physics. There's a group looking for exotic physics. These are things like these pairs [00:20:30] of upward going particles. Also looking for other oddities such as magnetic monopoles. There's a group that's looking for neutrinos that might be produced from weakly interacting. Massive particles, IAA, dark matter, but there's a group that's monitoring the rates of the detector. This scalers looking for Supernova and oh, there's also a group looking for talented Trinos, which is the this very distinctive topology town. Neutrinos are sort of the third flavor of neutrinos and those are [00:21:00] mostly only produced by extraterrestrial sources and they look very distinctively. You would look for case where you see two clusters of energy and the detector separated by a few hundred meters. Speaker 5: Looking at what's next, what would be the sort of ideal laboratory? If you want something that's very big, obviously Antarctica is a great challenge. Can you do neutrino detection in space for instance? [inaudible] Speaker 3: hmm, that's an interesting question. There are people who [00:21:30] are talking about that and the main application is trying to look for these cosmic gray air showers. The best experiments to study high energy, cosmic gray air showers are these things called air shower arrays, which are an array of detectors. Um, the largest one is something called the OJ Observatory in Argentina. It covers about 3000 square kilometers with an array of detectors on kind of a one and a half kilometer grid. And that's about as largest surface detector as you could imagine. Building the alternative [00:22:00] technology is look for something called air fluorescents. When the showers go through the air, they light it up. Particularly the nitrogen is excited and in that kind of like a fluorescent tube. So you see this burst of light as the shower travels through the atmosphere. O J in addition to the surface detectors has these cameras called flies eyes that look for this fluorescence, but it's limited in scale. And people have proposed building experiments that would sit on satellites or a space station [00:22:30] and look down and look at these showers from above. They could cover a much larger area. They could also look for showers from upward going particles, I. E. Neutrino interactions. But at this point that's all pretty speculative. Speaker 5: And when's your next trip to Antarctica? Uh, that's all depending on funding. I would like to go again and hopefully soon. I think I'm cautiously optimistic. We'll be able to go again this year. Hmm. Spencer in Thorsten. Thanks for joining us. Thank you. Thank you. Speaker 4: [00:23:00] [inaudible] regular feature of spectrum is to mention a few of the science and technology events that are happening locally over the next few weeks. Lisa Katovich joins me for that Speaker 6: calendar. The August general meeting of the East Bay Astronomical Society is Saturday, July 14th at the Chabot space and science centers, Dellums [00:23:30] building 10,000 Skyline Boulevard in Oakland. Ezra Bahrani is the evening Speaker. The title of his talk is UFOs, the proof, the physics and why they're here. The meeting starts at 7:30 PM Speaker 2: join Nobel laureates and social and environmental justice advocates at the towns and Tay Gore third annual seminar for Science and technology on behalf of the peoples of Bengali and the Himalayan basins, the subject, the global water crisis [00:24:00] prevention and solution. Saturday, July 21st 1:30 PM to 7:30 PM the event is jointly sponsored by UC Berkeley's department of Public Health and the international institute of the Bengali and Himalayan basins. Guest Speakers include three Nobel laureates, Charles h towns, Burton Richter and Douglas Ashur off. Also presenting our Francis towns advocate for social justice, Dr. Rush, Gosh [00:24:30] and Sterling Brunel. The event will be held in one 45 Dwinelle hall on the UC Berkeley campus. That's Saturday, July 21st 1:30 PM to 7:30 PM for more details, contact the UC Berkeley School of Public Health, Speaker 6: the next science at cal lectures on July 21st the talk will be given by Dr Jeffrey Silverman and it's entitled exploding stars, Dark Energy, and the runaway universe. Dr Silverman has been a guest [00:25:00] on spectrum. His research has been in the study of Super Novi. His lecture will focus on how the study of supernovae led to the recent discovery that the universe is expanding, likely due to a repulsive and mysterious dark energy. It was these observations that were recently awarded the 2011 Nobel Prize in physics. The lecture is July 21st at 11:00 AM and the genetics and plant biology building room 100 Speaker 2: next to news stories. Speaker 6: 3000 species [00:25:30] of mosquitoes are responsible for malaria, dengue, a fever, yellow fever, West Nile virus, and cephalitis and many more diseases. In Burkina Faso alone, residents can expect 200 bytes a day. Rapid resistance to pesticides on the part of malaria mosquitoes has prompted researchers all over the globe to deploy novel strategies against this and other diseases. Targeting Dengue. A fever has an advantage over malaria as only one species. Eighties [00:26:00] Egypt die is responsible for spreading it versus the 20 species responsible for spreading malaria. A British biotechnology company called Oxitec has developed a method to modify the genetic structure of the male eighties Aegypti mosquito transforming it into a mutant capable of destroying its own species. In 2010 they announced impressive preliminary results of the first known test of 3 million free flying transgenic mosquitoes engineered [00:26:30] to start a population crash after infiltrating wild disease spreading eighties a Gyp dye swarms on Cayman Island. Speaker 6: Oxitec has recently applied to the FDA for approval of its mosquito in the u s with Key West under consideration as a future test site in 2009 key west suffered its first dengate outbreak in 73 years. Australian researchers are testing and mosquito intended to fight dengue, a fever bypassing the disruptive Wolbachia bacteria to other mosquitoes, a very [00:27:00] different approach than transgenic genes funded largely by the bill and Melinda Gates Foundation. The project has shown that the Wolbachia strain not only shortens the life of a mosquito, but also reduces the amount of virus it develops. Releases in Queensland, Australia last year showed that Wolbachia could spread through a wild population quickly and future test sites are under consideration. In Vietnam. Speaker 2: The UC Berkeley News Center reports a prototype network being installed by chemists at the University of California. Berkeley [00:27:30] will employ 40 sensors spread over a 27 square mile grid. The information the network will provide could be used to monitor local carbon dioxide emissions to check on the effectiveness of carbon reduction strategies now mandated by the state, but hard to verify built and installed by project leader Professor Ron Cohen and graduate student Virginia Tighe and their lab colleagues. The shoe box size sensors will continuously measure carbon dioxide, carbon monoxide, [00:28:00] nitrogen dioxide, and ozone levels as well as temperature, pressure and humidity streaming. The information live to the web through the site. beacon.berkeley.edu the sensor network dubbed Beacon stretches from the East Bay regional parks on the east to interstate eight 80 on the west from El Surrito on the north nearly to San Leandro on the south encompassing open space as well as heavily traffic areas. [00:28:30] Most of the sensors are being mounted on the roofs of local schools in order to get students interested in the connection between carbon dioxide emissions and climate change. The UC Berkeley researchers work with Oakland's Chabot space and science center to create middle school and high school activities using live sensor data stream through the web as part of the students energy and climate science curriculum. The beacon network is a pilot program funded by the National Science Foundation to determine what information can be learned [00:29:00] from a densely spaced network Speaker 1: [inaudible].Speaker 2: The music heard during the show is from most done at David's album, folk and acoustics made available through a creative Commons license 3.0 attribution.

Physicist Spencer Klein and Electrics Engineer Thorsten Stezelberger, both at Lawrenc Berkeley National Lab, describe the Neutrino Astronomical project IceCube, which was recently completed in Antarctica. They also go on to discuss proposed project Arianna.TranscriptsSpeaker 1: Spectrum's next [inaudible]. Welcome to spectrum [00:00:30] the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 2: Good afternoon. I'm Brad Swift, the host of today's show, Rick Karnofsky and I interview Spencer Klein and Torsten Stessel Berger about the neutrino astronomy project. Ice Cube. Spencer Klein is a senior scientist and group leader at Lawrence Berkeley National Lab. [00:01:00] He's a member of the ice cube research team and the Ariana planning group. Thorsten Stetso Berger is an electronics engineer at Lawrence Berkeley National Lab. He too is part of the ice cube project and the Ariana team. They join us today to talk about the ice cube project and how it is helping to better define neutrinos. Spencer Klein and Thorsten setser Berger. Welcome to spectrum. Speaker 3: Thank you. Thank you. Can you talk to us a little bit about neutrinos? [00:01:30] Well, neutrinos are subatomic particles which are notable because they barely interact at all. In fact, most of them can go through the earth without interacting. This makes them an interesting subject for astrophysics because you can use them to probe places like the interior of stars where otherwise nothing else can get out and are most of them neutrinos from those sources. There's a wide range of neutrino energies that are studied. Some of the lowest energy neutrinos are solar neutrinos which [00:02:00] come from the interior of our sun. As you move up to higher energies, they come from different sources. We think a lot of the more energetic ones come from supernovas, which is when stars explode, they will produce an initial burst of neutrinos of moderate energy and then over the next thousand years or so, they will produce higher energy neutrinos as ejected spans, producing a cloud filled with shock fronts and you're particularly interested in those high energy. Speaker 3: Yes, ice cube is designed to study those neutrinos and also [00:02:30] neutrinos from even more energetic neutrinos where we don't really know where they come from. There are two theories. One is that they come from objects called active Galactic Nuclei. These are galaxies which have a super massive black hole at their center and they're rejecting a jet of particles perpendicular, more along their axis. And this jet is believed to also be a site to accelerate protons and other cosmic rays to very high energies. The other possible source of ultra energy neutrinos [00:03:00] are gamma ray bursts, which are when two black holes collide or a black hole collides with a neutron star. And if the neutrinos don't interact or interact so rarely and weekly with matter, how do we actually detect them? Well, the simple answer is you need a very large detector. Ice Cube is one cubic kilometer in volume and that's big enough that we think we should be able to detect neutrinos from these astrophysical sources. Speaker 3: The other project we work on, Ariana is even bigger. It's [00:03:30] proposed, but it's proposed to have about a hundred cubic kilometers of volume. And so you have an enormous detector to detect a few events and once you detect them, how can you tell where they came from? Well, with ice cube we can get the incoming direction of the neutrinos to within about a degree. So what we do is we look for neutrinos. Most of what we see out of these background atmospheric neutrinos which are produced when cosmic rays interact in the earth's atmosphere. But on top [00:04:00] of that we look for a cluster of neutrinos coming from a specific direction. That would be a clear sign of a neutrino source, which would be, you know, and then we can look in that direction and see what interesting sources lie. That way we can also look for extremely energetic neutrinos which are unlikely to be these atmospheric neutrinos. Speaker 3: And how is it that you measure that energy? What happens is a neutrino will come in and occasionally interact in the Antarctic. Ice should mention that ice cube is located at the South Pole where [00:04:30] there's 28 hundreds of meters of ice on top of the rock below. Occasionally in Neutrino will come in and interact in the ice and if it's something called a type of neutrino called the [inaudible] Neutrino, most of its energy will go into a subatomic particle called the Meuron. Meuron is interesting because it's electrically charged. As it goes through the ice, it will give off light, something we call Toronto radiation. So we've instrumented this cubic kilometer of ice with over 5,000 optical [00:05:00] modules, which are basically optical sensors. And so we record the amount and arrival times of the light at these optical sensors. And from that we can determine the neutrino direction to about within a degree. Speaker 3: And we can also get an estimate of the energy. Um, essentially is the on is more energetic. It will also produce other electrically charged particles as it travels. Those will give off more light. And so the light output is proportional to the neutrino energy. So you're taking an advantage of the fact that there's [00:05:30] a lot of ice in Antarctica and also that it's very big. Are there other reasons to do it at the South Pole? Well, the other critical component about the ice is that it has to be very clear, shouldn't scatter light and it shouldn't absorb light. And in fact the light can travel up to 200 meters through the ice before being absorbed. This is important because that means we can have a relatively sparse array. You know, we have only 5,000 sensors spread over a cubic kilometer. That's only if the light can travel long distances through the ice. [00:06:00] And do you have to take into account that the ice in the Antarctic is not perfectly clean? Yes. When we reconstruct the neutrino directions, we use this sophisticated maximum likelihood fitter. Essentially we try all sorts of different Milan directions and see which one is the most likely. And that takes into account the optical properties of the ace and includes how they vary with depth. There are some dust layers in the ice where the absorption length is much shorter and some places, [00:06:30] well most of the ice where it's much better. Speaker 4: Our guests on spectrum today are Spencer Klein and Thorsten Stetson Burger from Lawrence Berkeley national lab. They are part of a physics project named Ice Cube. In the next segment they talk about working at the South Pole. This is KALX Berkeley. Speaker 3: Can you compare the two experiments, both ice Cuban on a little bit? Well, ice cube is designed [00:07:00] for sort of moderate energy neutrinos, but for the really energetic neutrinos are, they are rare enough so that a one cubic kilometer detector just isn't big enough. And so for that you need something bigger and it's hard to imagine how you could scale the optical techniques that ice cube uses to larger detectors. So that's why we looked for a new technique in it. Here I should say we, the royal, we either many people, many places in the world looking at different versions. And so what we've chosen is looking [00:07:30] for radio [inaudible] off the mission. You know, we have this interaction in the ice. Some of the time. If it's an electron Neutrino, it produces a compact shower of particles. That shower will have more negatively charged particles than positively charged. Speaker 3: And so it will emit radio waves, you know, at frequencies up to about a Gigahertz coherently, which means that the radio emission strength depends on the square of the neutrino energies. So when you go to very high neutrino energies, this is a preferred technique. Radio waves can [00:08:00] travel between 300 meters and a kilometer in the ice, which means you can get by with a much sparser array. So you can instrument a hundred cubic kilometers with a reasonable number of detectors. When Ariane is developed, it will get to access higher energies. Will it still didn't detect some of the moderately high energies that ice cube is currently reaching? No, and there's no overlap because of the coherence and just not sensitive. I mean, ice cube will occasionally see these much higher energy neutrinos, [00:08:30] but it's just not big enough to see very many of them. Uh, you commented on, or you mentioned the size of the collaboration. Speaker 3: Can you sort of speak about how big these projects are? Sure. Ice Cube has got about 250 scientists in it from the u s Europe, Barbados, Japan, and New Zealand. Oh yeah. And plus one person from Australia now. And that's a well established, you know, it's a large experiment. Arianna is just getting going. It's got, I'll say less than a dozen [00:09:00] people in it. Mostly from UC Irvine and some involvement from LDL. How many years have you had experience with your sensors in the field then? That's kind of a complicated question and that the idea of doing neutrino astronomy in the Antarctic ice has been around for more than 20 years. The first efforts to actually put sensors in the ice, we're in the early 1990s these used very simple sensors. We just had a photo multiplier tube, essentially a very sensitive [00:09:30] optical detector, and they sent their signals to the surface. There are no complicated electronics in the ice. Speaker 3: The first Amanda effort in fact failed because the sensors were near the surface where the light was scattering very rapidly. Turns out the upper kilometer of ice is filled with little air bubbles, but then as you get down in depth, there's enough pressure to squeeze these bubbles out of existence. And so you go from very cloudy ice like what you see if you look in the center of an ice cube and then you go deeper [00:10:00] and you end up with this incredibly clear ice. So the first efforts were in this cloudy ice. Then in the second half of the 1990s Amanda was deployed in the deep highs. This is much smaller than ice cube in many respects. The predecessor, of course, the problem with Amanda was this transmission to the surface. It worked but it was very, very touchy and it wasn't something you could scale to the ice cube size. So one where people got together and came up with these digital optical modules where all of the digitizing electronics [00:10:30] is actually in the module. We also made a lot of other changes and improvements to come up with a detector that would be really robust and then we deployed the first ice cube string in 2005 and continued and then the last string was deployed at the end of 2010 Speaker 5: so basically from the scientific point or engineering point of view, we're learning about the detector. We got data from the first strain. It was not very useful for take neutrino science but you can learn to understand [00:11:00] the detector, learn how the electronics behaves, if there is a problem, change code to get different data. Speaker 3: When we did see some new is in that run and there's this one beautiful event where we saw this [inaudible] from a neutrino just moving straight up the string. I think it hit 51 out of the 60 optical sensors. So we're basically tracking it for 800 meters. It was just a beautiful that Speaker 5: what is the lifelight down there? The food, the day to day, [00:11:30] we've never been there in the winter time, so I can only talk about a summer and in the summer you're there for something specific like drilling or deploying a, so to summertime keeps you pretty busy and you do your stuff and then afterwards you hang out a little bit to wind down. And sometimes with some folks playing pool or ping pong or watching movies or just reading something and then time [00:12:00] again for the sleep or sleeping. And the next day for drawing for example, we had three shifts. And so that kept you pretty, pretty busy. One season when I was thrilling there I was on what we call the graveyard shift. Starting from 11 to I think eight in the morning. I saw and yeah, it was daylight. You don't notice it except you always get dinner for breakfast and scrambled eggs and potatoes for dinner. Speaker 3: The new station at the South Pole is really very nice and I would [00:12:30] say quite comfortable, good recreational facilities. I mean, and I would say the food was excellent, really quite impressive and you get to hang out with a bunch of international scientists that are down there. How collegial isn't, it Speaker 5: depends a little bit on the work. Like when I was rolling on night shift, we mostly got to hang out with people running the station. That was fairly collegial. Speaker 3: There's actually not very many scientists at the South Pole. In the summer there were about 250 [00:13:00] people there and maybe 20 of them were scientists. Most of them were people dealing with logistics. These are people, you know, heavy equipment operators. Fuel Lees would get the fuel off of the plane, cooks people, and even then can building the station wasn't quite done yet. The drillers will lodge wide variety of occupations but not all that many scientists. How close are the experiments to the station? Speaker 5: They are quite a few experiments [00:13:30] based in the station. Ice Cube is a kilometer away about probably Speaker 3: Lamotta and a half to the, to the ice cube lab, which is where the surface electronics is located. Speaker 5: So it's pretty close walking distance called walk. But it depends. I mean I don't mind the calls or it was a nice walk but they have like ice cube, uh, drilling. We are like lunch break also. It's [00:14:00] a little bit far to walk kilometer out or even throughout depending where you drill. So we had a car to drive back and forth to the station to eat lunch. Otherwise you are out for too long. Speaker 3: Yeah, they give you a really good equipment and so it's amazing how plaza you can be about walking around when it's 40 below, outside. Speaker 5: Especially if you do physical work outside as part of drilling also. It's amazing how much of that cold weather Ikea you actually take off because you just [00:14:30] do staff and you warm up. Speaker 4: [inaudible] you are listening to spectrum on KALX Berkeley coming up, our guests, Spencer Klein and Torsten Stotzel Burger detail, the ice cube data analysis process, Speaker 3: the ongoing maintenance of Ice Cube Sarah Plan for its lifetime Speaker 5: for the stuff [00:15:00] in the eyes, it's really hard to replace that. You cannot easily drill down and take them out. They are plans, uh, to keep the surface electronics, especially the computers update them as lower power hardware becomes available. Otherwise I'm not aware of preventive maintenance. You could do with like on a car. Yeah. Speaker 3: I have to say the engineers did a great job on ice cube. About 98% of the optical modules are working. Most of the failures were infant [00:15:30] mortality. They did not survive the deployment when we've only had a handful of optical modules fail after deployment and all the evidence is we'll be able to keep running it as long as it's interesting. And is there a point in which it's no longer interesting in terms of how many sensors are still active? I think we'll reach the point where the data is less interesting before we run out of sensors now. Okay. You know, we might be losing one or two sensors a year. In fact, we're still at the point where [00:16:00] due to various software improvements, including in the firmware and the optical modules, each year's run has more sensors than the previous years. Even if we only had 90% of them working, that would be plenty. Speaker 3: And you know, that's probably a hundred years from now. What do we have guests on to speak about the LHC at certain they were talking about the gigantic amounts of data that they generate and how surprisingly long it takes for scientists to analyze that data to actually get a hold [00:16:30] of data from the detector. And you're generating very large amounts of data. And furthermore, it's in Antarctica. So how much turnaround time is there? Well, the Antarctica doesn't add very much time. We typically get data in the north within a few days or a week after it's taken. There is a bit of a lag and try and take this time to understand how to analyze the data. For example, now we're working on, for the most part, the data that was taken in 2010 and [00:17:00] you know, hope to have that out soon probably for summer conferences. But understanding how to best analyze the data is not trivial. For example, this measurement of the mule on energies, very dependent on a lot of assumptions about the ice and so we have ways to do it now, but we're far from the optimal method Speaker 5: and keep in mind that detector built, it's just finished. So before you always added in a little bit more. So each year the data looked different because you've got more sensors in the data. Speaker 3: [00:17:30] Let's say for things where turnaround is important. For example, dimension, these gamma ray bursts, there's where this happens when a bunch of satellites see a burst of x-rays or gamma rays coming from somewhere in the sky. They can tell us when it happened and give us an estimate of the direction. We can have an and I would say not quite real time, but you know that we could have turned around if a couple of weeks. We also measure the rates in each of the detectors. This is the way to look for low energy neutrinos from a [00:18:00] supernova that is essentially done in real time. If the detector sees an increase, then somebody will get an email alert essentially immediately. If we got one that looked like a Supernova, we could turn that around very quickly. So are the algorithms that you're using for this longer term analysis improving? Speaker 3: Yes. They're much more sophisticated than they were two years ago. I'd say we're gradually approaching and I'm ask some Todrick set of algorithm, but we're still quite a ways [00:18:30] to go. We're still learning a lot of things. You know, this is very different from any other experiment that's been done. Normally experiments if the LHC, if they are tracking a charged particle, they measure points along the track. In our case, the light is admitted at the trend off angle. About 41 degrees. So the data points we see are anywhere from a few meters to a hundred meters from the track. And because of the scattering of light, it's a not so obvious how to find [00:19:00] the optimum track and it's, you know, it's very dependent on a lot of assumptions and we're still working on that. And we have methods that work well. As I said, you know, we can get an angular resolution of better than a degree in some cases, but there's still probably some room to be gotten there. Speaker 5: And then also, I mean I'm not involved in the science, but I hear people have new ideas how to look at a data. So that's still evolving too. Speaker 3: Yeah. Like you know, one analysis that people are working on, but we don't have yet would [00:19:30] be a speculative search where you're looking for a pair of event, a pair of neo-cons going upward through the detector in the same direction at the same time, which would quite possibly be a signal of some sort of new physics. And it's certainly an interesting typology to look for, but we're not there yet. And are there different teams looking at the same data to try to find different results and broaden the search so to speak? Uh, yes. We have seven or eight different physics working [00:20:00] groups in each of those groups is concentrating on a different type of physics or a different class of physics. For example, one group is looking for point sources, you know, hotspots in the sky. Second Group is looking at atmospheric and diffuse neutrinos trying to measure the energy spectrum of the neutrinos. Speaker 3: We do see both the atmospheric and also looking for an additional component. There's a group doing cosmic ray physics. There's a group looking for exotic physics. These are things like these pairs [00:20:30] of upward going particles. Also looking for other oddities such as magnetic monopoles. There's a group that's looking for neutrinos that might be produced from weakly interacting. Massive particles, IAA, dark matter, but there's a group that's monitoring the rates of the detector. This scalers looking for Supernova and oh, there's also a group looking for talented Trinos, which is the this very distinctive topology town. Neutrinos are sort of the third flavor of neutrinos and those are [00:21:00] mostly only produced by extraterrestrial sources and they look very distinctively. You would look for case where you see two clusters of energy and the detector separated by a few hundred meters. Speaker 5: Looking at what's next, what would be the sort of ideal laboratory? If you want something that's very big, obviously Antarctica is a great challenge. Can you do neutrino detection in space for instance? [inaudible] Speaker 3: hmm, that's an interesting question. There are people who [00:21:30] are talking about that and the main application is trying to look for these cosmic gray air showers. The best experiments to study high energy, cosmic gray air showers are these things called air shower arrays, which are an array of detectors. Um, the largest one is something called the OJ Observatory in Argentina. It covers about 3000 square kilometers with an array of detectors on kind of a one and a half kilometer grid. And that's about as largest surface detector as you could imagine. Building the alternative [00:22:00] technology is look for something called air fluorescents. When the showers go through the air, they light it up. Particularly the nitrogen is excited and in that kind of like a fluorescent tube. So you see this burst of light as the shower travels through the atmosphere. O J in addition to the surface detectors has these cameras called flies eyes that look for this fluorescence, but it's limited in scale. And people have proposed building experiments that would sit on satellites or a space station [00:22:30] and look down and look at these showers from above. They could cover a much larger area. They could also look for showers from upward going particles, I. E. Neutrino interactions. But at this point that's all pretty speculative. Speaker 5: And when's your next trip to Antarctica? Uh, that's all depending on funding. I would like to go again and hopefully soon. I think I'm cautiously optimistic. We'll be able to go again this year. Hmm. Spencer in Thorsten. Thanks for joining us. Thank you. Thank you. Speaker 4: [00:23:00] [inaudible] regular feature of spectrum is to mention a few of the science and technology events that are happening locally over the next few weeks. Lisa Katovich joins me for that Speaker 6: calendar. The August general meeting of the East Bay Astronomical Society is Saturday, July 14th at the Chabot space and science centers, Dellums [00:23:30] building 10,000 Skyline Boulevard in Oakland. Ezra Bahrani is the evening Speaker. The title of his talk is UFOs, the proof, the physics and why they're here. The meeting starts at 7:30 PM Speaker 2: join Nobel laureates and social and environmental justice advocates at the towns and Tay Gore third annual seminar for Science and technology on behalf of the peoples of Bengali and the Himalayan basins, the subject, the global water crisis [00:24:00] prevention and solution. Saturday, July 21st 1:30 PM to 7:30 PM the event is jointly sponsored by UC Berkeley's department of Public Health and the international institute of the Bengali and Himalayan basins. Guest Speakers include three Nobel laureates, Charles h towns, Burton Richter and Douglas Ashur off. Also presenting our Francis towns advocate for social justice, Dr. Rush, Gosh [00:24:30] and Sterling Brunel. The event will be held in one 45 Dwinelle hall on the UC Berkeley campus. That's Saturday, July 21st 1:30 PM to 7:30 PM for more details, contact the UC Berkeley School of Public Health, Speaker 6: the next science at cal lectures on July 21st the talk will be given by Dr Jeffrey Silverman and it's entitled exploding stars, Dark Energy, and the runaway universe. Dr Silverman has been a guest [00:25:00] on spectrum. His research has been in the study of Super Novi. His lecture will focus on how the study of supernovae led to the recent discovery that the universe is expanding, likely due to a repulsive and mysterious dark energy. It was these observations that were recently awarded the 2011 Nobel Prize in physics. The lecture is July 21st at 11:00 AM and the genetics and plant biology building room 100 Speaker 2: next to news stories. Speaker 6: 3000 species [00:25:30] of mosquitoes are responsible for malaria, dengue, a fever, yellow fever, West Nile virus, and cephalitis and many more diseases. In Burkina Faso alone, residents can expect 200 bytes a day. Rapid resistance to pesticides on the part of malaria mosquitoes has prompted researchers all over the globe to deploy novel strategies against this and other diseases. Targeting Dengue. A fever has an advantage over malaria as only one species. Eighties [00:26:00] Egypt die is responsible for spreading it versus the 20 species responsible for spreading malaria. A British biotechnology company called Oxitec has developed a method to modify the genetic structure of the male eighties Aegypti mosquito transforming it into a mutant capable of destroying its own species. In 2010 they announced impressive preliminary results of the first known test of 3 million free flying transgenic mosquitoes engineered [00:26:30] to start a population crash after infiltrating wild disease spreading eighties a Gyp dye swarms on Cayman Island. Speaker 6: Oxitec has recently applied to the FDA for approval of its mosquito in the u s with Key West under consideration as a future test site in 2009 key west suffered its first dengate outbreak in 73 years. Australian researchers are testing and mosquito intended to fight dengue, a fever bypassing the disruptive Wolbachia bacteria to other mosquitoes, a very [00:27:00] different approach than transgenic genes funded largely by the bill and Melinda Gates Foundation. The project has shown that the Wolbachia strain not only shortens the life of a mosquito, but also reduces the amount of virus it develops. Releases in Queensland, Australia last year showed that Wolbachia could spread through a wild population quickly and future test sites are under consideration. In Vietnam. Speaker 2: The UC Berkeley News Center reports a prototype network being installed by chemists at the University of California. Berkeley [00:27:30] will employ 40 sensors spread over a 27 square mile grid. The information the network will provide could be used to monitor local carbon dioxide emissions to check on the effectiveness of carbon reduction strategies now mandated by the state, but hard to verify built and installed by project leader Professor Ron Cohen and graduate student Virginia Tighe and their lab colleagues. The shoe box size sensors will continuously measure carbon dioxide, carbon monoxide, [00:28:00] nitrogen dioxide, and ozone levels as well as temperature, pressure and humidity streaming. The information live to the web through the site. beacon.berkeley.edu the sensor network dubbed Beacon stretches from the East Bay regional parks on the east to interstate eight 80 on the west from El Surrito on the north nearly to San Leandro on the south encompassing open space as well as heavily traffic areas. [00:28:30] Most of the sensors are being mounted on the roofs of local schools in order to get students interested in the connection between carbon dioxide emissions and climate change. The UC Berkeley researchers work with Oakland's Chabot space and science center to create middle school and high school activities using live sensor data stream through the web as part of the students energy and climate science curriculum. The beacon network is a pilot program funded by the National Science Foundation to determine what information can be learned [00:29:00] from a densely spaced network Speaker 1: [inaudible].Speaker 2: The music heard during the show is from most done at David's album, folk and acoustics made available through a creative Commons license 3.0 attribution.
