Podcasts about Oxitec

Biological control company Oxitec recently launched Sparks, a new platform designed to rapidly scale Wolbachia replacement technology to take on dengue fever.Backed by a multi-million-dollar investment from the Gates Foundation, Sparks adds to Oxitec's Aedes aegypti technology, called Friendly, which is taking on dengue fever in Brazil. With mosquito-borne diseases on the rise, Oxitec's Friendly mosquitoes are designed to suppress populations of disease-spreading mosquitoes and, in turn, reduce biting and the threat of disease transmission. Wolbachia-carrying mosquitoes are designed to spread Wolbachia bacteria into the local mosquito population to limit the ability of the remaining infected mosquito population to transmit dengue. The platforms are designed for specific settings and intervention types, and provide options for governments and communities seeking suppression, replacement or hybrid approaches using both.Our guest on the podcast this week is the CEO of Oxitec, Grey Frandsen.00:56-02:12: About Oxitec02:12-05:54: The state of mosquito-borne diseases05:54-07:09: The effect of climate change07:09-08:29: Moving into more developed countries08:29-10:27: Wolbachia replacement technology10:27-12:53: The Sparks program12:53-13:46: Other companies' approaches13:46-15:00: World Mosquito Program15:00-15:30: Establishing timelines15:30-17:20: The effect on the environment17:20-18:54: Could adaptation render the technology useless?18:54-20:52: Are the Sparks and Friendly programs being used together?20:52-21:57: Do the technologies work differently on different species?21:57-26:28: How to determine rollout conditions26:28-27:19: Are repeat interventions needed?27:19-30:32: Are there limitations based on cost or politics?30:32-33:11: Are the technologies applicable to other problems?33:11-35:08: Is there anything else in Oxitec's pipeline?Interested in being a sponsor of an episode of our podcast?

„Často mi připadá, že si hrajeme na bohy, a někdy s výsledkem, který skončí jinak, než jaký byl úmysl. Například britská firma Oxitec ujišťovala, že její modifikovaní komáři po vypuštění nemohou přežít, jenže pak přiznala, že jich přežilo 15 %. Takže my vlastně vytváříme jakéhosi superkomára, u kterého nevíme, co je schopen v přírodě napáchat za škody,“ říká Radovan Dluhý-Smith v rozhovoru pro pořad Kupředu do minulosti. 2. díl, 17.05.2024, www.RadioUniversum.cz

In this 168th episode of the Live Healthy Be Well podcast, Jeffrey answers audience questions.  In the first segement he discusses how many of the public policy decisions regarding GMOs are not based on science but more on the influence of industry on political appointments. In the second segment, Jeffrey talks about his argument with Derric Nimmo, head of public health research at Oxitec, about the recent release of GM mosquitoes in several countries.  Jeffrey ended up educating the Oxitec scientist about the lack of stringent research on the saliva of GM mosquitoes which could lead to devastating consequences for humans.

Spurred on by the war in Ukraine, we're seeing a worldwide shift to green energy, with the global demand of fossil fuels now expected to peak in 15 years - a dose of optimism ahead of COP27. The climate conference kicks off in Egypt on November 6, and the team brings a round-up of what we can expect. Maddie and Rowan also discuss their recent visit to the London Literature Festival, where they saw Greta Thunberg speak.‘Marsquakes' studied by NASA's InSight lander suggest Mars may still be volcanically active - and it may have a subsurface water table similar to the one on Earth. The team says this is exciting news for the prospect of life existing on the Red Planet.“A victory not only for the region, but for humanity and life itself.” Brazil's President Jair Bolsonaro has been unseated by Luiz Inácio Lula da Silva. The team explains how Bolsonaro has presided over climate catastrophe, and why this news has sparked celebration - and relief - from environmentalists.Genetically modified mosquitoes have been released in a city in Brazil. The team explains how UK-based biotechnology firm Oxitec have done this in an effort to find ways to eliminate mosquitoes. The insects transmit deadly diseases like malaria, which kills more than 600,000 people a year.And we bring you a controversial ‘Lifeform of the Week' - everyone's most hated amphibian, the cane toad. Quite disturbingly, the team explains how new x-ray video footage shows that cane toads lick their own hearts when they swallow prey. Gross.

In 2008 the Bill and Melinda Gates Foundation financed Jichi Medical University in Japan to develop “a mosquito that can produce and secrete a malaria vaccine protein.” The initiative was aimed at creating a “flying syringe, to deliver protective vaccine via saliva.” In 2010 they gave money to UK-based biotech company Oxitec to develop genetically modified mosquitoes that could be lethal to carriers of dengue, zika, and yellow fever. Science Magazine published a report that year on this Japanese research and discussed what they called “flying vaccinators.” In 2015 the people of Florida, set to be the Oxitec testing ground, signed a petition against such open-air lab trials. In 2021 the trial proceeded regardless and in April 2022 Nature published a report on the results which found that although mosquitoes died in large numbers there was no reduction in disease spread or need for pesticides, which often cause the very symptoms of the diseases. A few days ago a mosquito-malaria-vaccine trial was carried out in Washington State. Of 14 participants, 7 were diagnosed with malaria leading researchers to declare their mosquito-vaccine was 50% effective. However, they made no mention of how the other half of the group could be exposed to ‘malaria' and yet not develop the disease with its vague ‘symptom complex' list. There is no question why such a malaria vaccine should be tested in the U.S. where cases rarely top 2,000 and where death rarely reaches double digits. Meanwhile, Africa is home to 95% of cases and 96% of deaths, while India is home to most of the world's polio. It is likely these ‘disease' are caused by environment, as demonstrated by official WHO data, rather than tiny invisible particles. While focus has been on the mosquito, the NIH and B&MGF have also been researching a needle-less vaccine. Such research goes back to Spain in 1999 where researchers were able to spread vaccine-induced antibodies to non-vaccinated rabbits via vaccinated rabbits. All was done in natural interaction without needle, misquotes, or any other tool.

Mosquitoes are the world's most dangerous animals, vectoring dozens of diseases. One of the major disease vectors is Ades aegypti, an invasive insect with an ever-expanding range. Municipalities have turned to insecticides for control, which can impact beneficial insects. Sterile insect techniques, performed by mutagenizing mosquitoes to sterility, can work well in controlling insect populations. Over the last decade, Oxitec has advanced technologies that use a molecular techniques to repress development of mosquitoes in subsequent populations. Release of their genetically engineered males leads to decreasing populations of resident mosquitoes.  In this week's podcast we discuss the risks, benefits, and overall strategy, along with the company's public communications efforts, with the goal of increasing deployment of this technology when it can complement pubic health initiatives. 

A swarm of genetically engineered mosquitoes might be released in California. KCSB's Crystal Martinez has the story.

Vous connaissiez le maïs OGM destiné à pousser sans avoir besoin de beaucoup d'eau ? Et bien aujourd'hui, place au moustiques génétiquement modifiés, qui au lieu de résoudre les problèmes de faim dans le monde, pourraient tout simplement sauver la biodiversité, ou a minima, la préserver. Je sais, ça peut paraître étonnant étant donné qu'avec un demi-million de victimes chaque année, le moustique est l'espèce la plus meurtrière pour l'Homme. Qu'à cela ne tienne, une société britannique est bien décidée à relâcher deux milliards de moustiques OGM pour justement réguler de façon naturelle la population des moustiques, et ainsi préserver l'environnement.Depuis plusieurs années, des entreprises comme l'américain Google ou l'anglais Oxitec expérimentent de nouvelles manières de diminuer la population de moustiques. L'entreprise Britannique a par ailleurs déjà procédé à des lâchers de moustiques OGM ces dernières années, avec un résultat assez satisfaisant qui aurait permis de limiter leur prolifération. Plutôt que de relâcher à nouveau 750 millions de moustiques OGM dans la nature Oxitec devrait prochainement en libérer deux milliards ! Ceci dit, de quels moustiques parle-t-on ? Concrètement ce seront tous des mâles appartenant à l'espèce Aedes aegypti. Objectif : que ces derniers se reproduisent avec des femelles, qui donneront naissance à des larves non-viables. En clair, ces larves mourront toutes avant l'âge adulte, empêchées par les gênes du mâle de produire une protéine nécessaire à leur développement.D'après les scientifiques, ces moustiques génétiquement modifiés seraient inoffensifs pour l'environnement. Il s'agirait même d'une méthode a priori moins risquée que le fait d'assécher les zones humides où prolifèrent les moustiques, ou bien de pulvérisation de l'insecticide qui tue également d'autres insectes comme les abeilles. Ainsi, cette technique réduirait mécaniquement la population de moustique sans l'éradiquer totalement. La modification génétique apportée ne serait pas non plus néfaste pour l'alimentation de leurs prédateurs, comme les oiseaux et les chauves-souris d'après les chercheurs, ni même pour l'homme, étant donné qu'il ne s'agit que de mâles et que ce ne sont que les femelles qui piquent.

   MP3 Download Link:Click Here To Download: Genetically Modified Mosquitoes In Africa : Nigerian News Updates {Automated Transcript. Contains Typos. Not Yet Edited By A Human}:hello everybody i'm alfred and i'd like to talk to you about you know genetically modified mosquitoes in africa you know there's been a lot of talk about that and you know i wouldn't put it past the globalist to actually do that you know it would make a lot of sense they are actually disappointed that in spite of their prophecies and their expectations you know melinda gates came out and said that she see dead bodies all across africa you know when these same people who sponsored the the creation of the um wuhan virus you know the same people who sponsor the creation of the uh kovid 19 who are looked upon as heroes today for so-called giving the world the solution of the vaccine which does not work but they are creating vaccine passports demands you know left right and center the same people that wanted africa depopulated i will not put it past them that they will have genetically modified mosquitoes to carry um the thenew strains of the virus you know and people need to ask themselves where do these new strains come from if the original covet has been said that it came from a lab what makes you think that the new strains didn't come from a lab and who is still making them who actually is there more defined and creating new strains of the virus you know these are not mutations these are not natural mutations the virus is not naturally mutating a virus that is so weak that people's immune systems are killing it off that is not it is not mutating into new strains and people are so and and the government is predicting oh by this year there will be this virus oh this is the vertebrate oh there will be this virus oh there will be this virus they have already planned and outlined and showed oh by this time there will be these variants also there will be need for this measure and that measure oh there'll be need for this kind of enforcement of force they they need for this kind of enforcement of vaccines and all those all those kinds of nonsense you see um we need to stand um strong on common sense and not be victims otherwise you know we have ourselves to blame the concept of genetically modified mosquitoes it goes it's first of all um what stops it from being possible but you know in any case when it comes to the solutions of things like this number one africa needs to be stopped being dependent on foreign nations the more africa is geared to be dependent on foreign nations and the more african leaders are putting themselves in that situation no nation expertly foreign nation is going to put itself in a position where africa will be greater than them so why are you always building your economy on the generosity or so-called generosity of other nationswhy are you getting into debt at the hands of these other nations and globalist organizations like the world bank and the united nations the more you do such things the more you jeopardize africa you know and why is it that the medical community in spite of the fact that you knowthe same brains you know god gave the white man one brain god also gave the app the africa won't bring why is it that you always need um medical help from outside look at the nigerian president he just recently returned from i believe uk again in the name of medical visits he's spending so much time in uk with taxpayers money than it he is in nigeria he doesn't know that that's the that that it's a shame it is a shame in spite of all the nigerians that have gone um overseas and have lent and have studied and told me that it is impossible for any of them to build a hospital that functions within nigeria you see why the nigerian president is busy flying to uk for medical attention there are medical strikes hospitals in nigeria are going on strike you know governments either you know um not private hospitals but um mostly government-run hospitals because of the mismanagement and a lot of nonsense that is happening the government still does not want to listen to what's the ma what the doctors are sayingwith regards to whether it is vaccine covered of them being paid properly the government does not listen to the people and the and the leader of the government is like well if all the nigerians die he doesn't care he's going to the uk for his own health care this is a man that is up there in years and all he's concerned about his bully himself and as far as he's concerned his children are citizens of foreign nations and they are doing well with nigerian money living off of nigeria money nigeria taxpayers money so um these kinds of nonsense the kind of leaders look at um south africa you know they wanted to bring the the ex-president sorry the former president to just to stand regarding corruption but you see america is also corrupt their government is also corrupt as well as in many nations but africa you know the corruption is something else and the corruption of the leaders is a big motivating factor to all these kinds of things i will not be surprised you know when everything in africa is running on the engine of the charity and the so-called benevolence and generosity of the united nations and the world bank why wouldn't africa be a mess when africans who have the national resources of the world refuse to stand up they will kill you and take your natural resources so as long as you remain an idiot this is what your your future holds you know so um this matter of the genetically modified mosquitoes you know there's also the talk because i once saw an article you know i can't find it anymore where there was talks about you know genetically motive modifying meat so that people would get vaccinated so they wanted to put a vaccine in meat so when people go to the market they're buying meats you know the vaccine will be inside the meat in the name of health regulation and you know making it safer because all these ingredients that they put in food that there are different government and health so-called health organizations keep in mind that the world health organization is the biggest of them these people can mandate and say oh this has to be in the midst this has to be it is for the safety is going to help but they are including all kinds of things that are modifying the bodies of the individuals when human beings are now eating food that is genetically modified most of which is sent to africa africa is the testing ground for all experiments all human experiments in mass africa is the testing ground and africa still has leaders that wants to operate on the the benevolence and the generosity of of the u.n and all these globalist nations so that they can be coming to africa and and putting all kinds of nonsense in the food and using africans for experiments from ebola to zika virus and every other thing it is africa that is a testing ground for all these man-made viruses including hiv hiv is not a natural occurrence hiv was not created naturally he did not come naturally into existence and of course these kinds of things are deployed in africa because they want to decrease the populations of africa so you can be doing all your blm nonsense but what is the point of blm when they are killing many of you thanks to blm how many african americans have been killed so they are on one hand they are like oh we support african americans we support people of african descent oh we support africa but they are doing things you know they don't mind so-called giving you um a so-called platform and a so-called voice when they are killing you you know it's like signing a treaty with somebody who you know you have already poisoned and it's about to die when you're about to when you have already poisoned somebody who you are signing a peace treaty one of the points you know that the peace city is is just for sure because you have already poisoned that personal person is about to die so our heart they are saying oh we are all for blm oh we are all for um black lives oh we are all for africans i won't even go into the topic of calling people black right now but you know that they're like we're all for this all this but at the same time you would see that what they are doing is leading to more debts of people of african descent of africans they know what they are doing so you know you need to be wise you know you need to be wise that is just the fact you need to be wise you know um i won't put it past anybody the genetically modified mosquito there's a lot of genetically modified um food already so why not mosquitoes and then release it in africa and then um see what happens next but of course we are going to pray and we are going to preach the gospel and the same god that heals the sick you know is going to work and keep us safe from whatever these people are planning in that area and in addition to that we are going to make sure that africa has autonomy africa has real freedom and independence from the world because africa does not have independence africa is not economically independent the economy of africa is based on the world bankand we have um foolish people running the central banks of so-called african um currencies and and you know look at look at look at nigeria the nigerian naira is based on the dollar which is losing value every blessed day why would you base your currency on dollar instead of natural resources which you have why are you so stupid you see so um all of this nonsense just keeps on going on you know africa is owned by globalists africa is not independentafrica is not you know so africa the people of africa need to realize um what is really happening and africans need to stand up and truly become independent and free that being said make sure you check out afraid of vip if you have not given a life to christ

Not Yet Edited By A Human}:hello everybody i'm alfred and i'd like to talk to you about you know genetically modified mosquitoes in africa you know there's been a lot of talk about that and you know i wouldn't put it past the globalist to actually do that you know it would make a lot of sense they are actually disappointed that in spite of their prophecies and their expectations you know melinda gates came out and said that she see dead bodies all across africa you know when these same people who sponsored the the creation of the um wuhan virus you know the same people who sponsor the creation of the uh kovid 19 who are looked upon as heroes today for so-called giving the world the solution of the vaccine which does not work but they are creating vaccine passports demands you know left right and center the same people that wanted africa depopulated i will not put it past them that they will have genetically modified mosquitoes to carry um the thenew strains of the virus you know and people need to ask themselves where do these new strains come from if the original covet has been said that it came from a lab what makes you think that the new strains didn't come from a lab and who is still making them who actually is there more defined and creating new strains of the virus you know these are not mutations these are not natural mutations the virus is not naturally mutating a virus that is so weak that people's immune systems are killing it off that is not it is not mutating into new strains and people are so and and the government is predicting oh by this year there will be this virus oh this is the vertebrate oh there will be this virus oh there will be this virus they have already planned and outlined and showed oh by this time there will be these variants also there will be need for this measure and that measure oh there'll be need for this kind of enforcement of force they they need for this kind of enforcement of vaccines and all those all those kinds of nonsense you see um we need to stand um strong on common sense and not be victims otherwise you know we have ourselves to blame the concept of genetically modified mosquitoes it goes it's first of all um what stops it from being possible but you know in any case when it comes to the solutions of things like this number one africa needs to be stopped being dependent on foreign nations the more africa is geared to be dependent on foreign nations and the more african leaders are putting themselves in that situation no nation expertly foreign nation is going to put itself in a position where africa will be greater than them so why are you always building your economy on the generosity or so-called generosity of other nationswhy are you getting into debt at the hands of these other nations and globalist organizations like the world bank and the united nations the more you do such things the more you jeopardize africa you know and why is it that the medical community in spite of the fact that you knowthe same brains you know god gave the white man one brain god also gave the app the africa won't bring why is it that you always need um medical help from outside look at the nigerian president he just recently returned from i believe uk again in the name of medical visits he's spending so much time in uk with taxpayers money than it he is in nigeria he doesn't know that that's the that that it's a shame it is a shame in spite of all the nigerians that have gone um overseas and have lent and have studied and told me that it is impossible for any of them to build a hospital that functions within nigeria you see why the nigerian president is busy flying to uk for medical attention there are medical strikes hospitals in nigeria are going on strike you know governments either you know um not private hospitals but um mostly government-run hospitals because of the mismanagement and a lot of nonsense that is happening the government still does not want to listen to what's the ma what the doctors are sayingwith regards to whether it is vaccine covered of them being paid properly the government does not listen to the people and the and the leader of the government is like well if all the nigerians die he doesn't care he's going to the uk for his own health care this is a man that is up there in years and all he's concerned about his bully himself and as far as he's concerned his children are citizens of foreign nations and they are doing well with nigerian money living off of nigeria money nigeria taxpayers money so um these kinds of nonsense the kind of leaders look at um south africa you know they wanted to bring the the ex-president sorry the former president to just to stand regarding corruption but you see america is also corrupt their

Le zanzare, si sa, non sono più quelle “di una volta”. Negli ultimi decenni, la globalizzazione e i cambiamenti climatici hanno portato alla diffusione in Italia e in Europa di specie di zanzare esotiche. Queste specie non solo hanno cambiato la vita di tutti noi a causa del loro comportamento aggressivo, ma hanno creato le condizioni per la trasmissione di virus esotici capaci di causarci gravi patologie.L'azienda di biotecnologia Oxitec con sede ad Abingdon, nel Regno Unito, ha rilasciato per la prima volta negli Stati Uniti delle zanzare geneticamente modificate per contrastare il significativo aumento delle malattie causate da questi insetti.

This week, mosquito eggs placed in the Florida Keys are expected to hatch tens of thousands of genetically modified mosquitoes, a result of the first U.S. release of such insects in the wild. A biotechnology firm called Oxitec delivered the eggs in late April as part of a federally approved experiment to study the use of genetic engineering—rather than insecticides—to control disease-carrying mosquito populations. The move targets an invasive species, called Aedes aegypti, that carries Zika, dengue, chikungunya, yellow fever and other potentially deadly diseases, some of which are on the rise in Florida. The experiment relies on a genetic alteration that will be lethal to a large number of future offspring. In this case, male mosquitoes have been modified to carry a gene that makes their female progeny dependent on the antibiotic tetracycline—and thus fated to die in the wild. As the mating cycle repeats over generations, female numbers are depleted, and the population is suppressed. The modified insects eventually die off, making this approach self-limiting Oxitec overcame significant regulatory hurdles before getting the go-ahead from the U.S. Food and Drug Administration in 2016 and then the Environmental Protection Agency in 2020. If the current pilot effort is successful, the firm is set to release as many as 20 million more males in the prime of Florida's mosquito season later this year. The results of the experiment could ultimately help address concerns about releasing genetically modified organisms into the wild. --- Send in a voice message: https://anchor.fm/thes3podcast/message

Piracicaba poderá contar com a retomada do Aedes do Bem para o combate ao mosquito transmissor da dengue. O projeto foi implementado na cidade de 2015 a 2019 pela empresa Oxitec, de Campinas. A possibilidade de Piracicaba retomar o projeto foi anunciada pela vereadora Ana Pavão (PL) nesta semana. ---------- Começaram esta semana as obras de restauro da escola estadual Sud Mennucci. Como conta a diretora Márcia Aparecida Lima Vieira, a unidade recebeu visitas técnicas das equipes de engenharia da construtora e da FDE (Fundação para o Desenvolvimento da Educação) no início deste mês de fevereiro e o processo deve seguir até o final de julho deste ano.

Hoy vamos a hablar de un problema que ha aquejados al ser humano desde que el australopitécido dio sus primero pasos. Se trata de los mosquitos. En Puerto Rico sabemos un poco de eso. Por acá tenemos una especie llamada aedes aegypti que entre otras cosas propaga el Zika, el dengue, el chikungunya y la fiebre amarilla. ¡Casi na’!!! Y a pesar de lo seria que se pone la situación en ocasiones, tengo entendido que se queda corta cuando la comparamos con el sur de la Florida. Particularmente durante los meses de julio y agosto. La compañía Oxitec —del Reino Unido— ha creado una solución innovadora que promete acabar con el Aedes Egipti en un 95%. Pero claro, por tratarse de una solución genética, ha levantado todo tipo de sospechas en la comunidad y protestas tildándola de Frankenstein y de Jurasic Park. Lo que en sus comienzos fue un problema médico y científico se ha convertido en un problema de Relaciones Públicas y de comunicación. Además, te presento el episodio número 4 de mi nueva serie de videos: “Con Ese Cuento A Otra Parte”. en el que discuto el tema de “La Ingeniería Social y El Phishing”. No te lo pierdas.

La empresa Oxitec, con sede en Reino Unido, pero operaciones en Estados Unidos, ha recibido la aprobación del Estado de Florida para liberar a 750 millones de mosquitos genéticamente modificados en los pantanos de Florida. El objetivo es lograr la cruza de los machos liberados con las hembras nativas para disminuir la población de los mismos y controlar brotes de dengue y zica. Organizaciones ambientalistas están en contra del proyecto.

The South Florida/Keys mosquito control board is planning to vote on August 18th to allow for the release of 500,000,000 genetically modified mosquitoes as a mosquito abatement campaign.  The stated purpose of the release is to reduce the population of a small subset of natural mosquitoes by causing their female larvae to die. But based on past releases of mosquitoes by the same company, Oxitec, their technology probably won’t work at all. Furthermore, even though Oxitec claimed that its mosquitoes would simply die out after the experiment was over, studies proved them wrong. They permanently altered the genetic makeup of natural mosquitoes, which could have serious consequences for health and the environment.

EPA has given biotech company Oxitec the go-ahead to test the effectiveness of genetically modified mosquitoes in parts of Florida and Texas, generating environmental safety concerns. Also, a federal appellate court recently found EPA did not adequately consider risks and problems when it approved the herbicide Dicamba for new uses. That approval has created huge problems for farmers who do not use the chemical or who don't want to buy seeds of genetically modified crops that can tolerate it.

The mamas take a look into Oxitec and their GMO Mosquito programs. First denied by the trump EPA boss Scott Pruitt, it found new acceptance under "Super Polluter" EPA boss Andrew Wheeler - who never met a coal fire He did not enjoy! Oxitec not only invented the GMO mosquito, they also wrote the risk evaluations, and all of the "evidence" to convince Wheeler that a 3% failure rate in the Florida Keys was totally worth it! Add to that a Saharan Sand Storm coming to America, a plague of locusts eating their way through 2 contents, leading to exponential famine couple that with trump and Modi being ineffectual leaders and we have the recipe for the end of times! www.HeartlandMamas.com#DemCast

What is it and how does it work? What are the criticisms and concerns? We exam these questions in this short podcast. […] The post Genetically modified mosquitoes coming to the Florida Keys? appeared first on Outbreak News Today.

Scientists are now saying that genetically modified mosquitoes developed by Oxitec may have impacted the actual genetics of the natural mosquito populations where these bioengineered bugs were released and consequently, made them stronger. Now, the population of these super hybrid mosquitoes has grown and are carriers of Zika, Yellow Fever, and Dengue. On tonight's show, Clyde Lewis talks with Dr. John Norris and Ryan Gable about GLOBAL SWARMING - THE PLAGUE OF THE GMOSQUITOES

Uma tentativa de criar mosquitos transgênicos para conter a população do Aedes aegypti e controlar a transmissão de dengue, febre amarela, zika e chikungunya pode ter tido efeito contrário e produzido insetos híbridos mais resistentes. É o que indica um artigo publicado no início de setembro pela “Scientific Reports”, do grupo Nature Research, que cogita a possibilidade de o cruzamento entre diferentes espécies ter criado um “supermosquito”. A empresa britânica de biotecnologia Oxitec é a responsável pelo experimento e liberou esses mosquitos em cinco cidades brasileiras: Jacobina e Juazeiro, na Bahia, Piracicaba e Indaiatuba, em São Paulo, e Juiz de Fora, em Minas Gerais. A publicação do artigo gerou controvérsias e foi assunto de uma reportagem publicada esta semana no caderno Interessa, do jornal O Tempo. Para explicar todas as questões envolvidas no caso nós convidamos a reporter Litza Mattos, autora da matéria, para o episódio do Tempo Hábil desta semana. Ouça!

Mosquitoes are more than just pesky. Certain types of insect serve as efficient vectors for infectious diseases that pose great harm to humans. Oxitec, a subsidiary of Intrexon, has developed a genetically altered male of the Aedes aegypti mosquito designed to mate with wild females to produce offspring that die before becoming adults. The effort is meant to provide a highly targeted alternative to insecticides that are broad acting, can cause harm to humans and other animals, and may be unable to effectively reach their intended targets in urban environments. We spoke to Hadyn Parry, CEO of Oxitec, about how the company breeds billions of mosquitos that can't reproduce, how it delivers them to where they are needed, and how the company is addressing the regulatory barriers to demonstrate its technology is safe and effective.

Today's guests have been separately on the program recently. And we've asked them, both Brits, to come back on for a discussion of the Brexit. Clare Turnbull is Clinical Lead for the 100K Genomes Project Cancer Program at Genomics England. Hadyn Parry is the CEO at Oxitec, a company based in Oxford which is already selling their genetically engineered mosquitos into Brazil to deal with viral diseases like Zika and Dengue Fever.

Today we travel to a future where humans have decided to eradicate the most dangerous animal on the planet: mosquitos. How would we do it? Is it even possible? And what are the consequences?     Mosquitos have worked hard to earn the nickname “deadliest animal on earth.” According to the World Health Organization there are 20 million cases of dengue virus every year. And there are 214 million cases of malaria, 438,000 of which are deadly. In the United States, an outbreak of West Nile Virus that started in 1999 infected 41,000 people and killed 1700 of them. Since 2005, there have been 1.9 million cases of Chickungunya virus documented in East Asia, and as of last year 1.3 million cases of the virus had been documented in the US and Latin America. Yellow Fever infects 200,000 people every year, and kills about 30,000 of those people.     All of these diseases are carried by mosquitos. For comparison, snakes kill about 50,000 people a year. Humans kill about 475,000 other humans every year. And mosquitos, all told, kill 725,000 people each year.     And recently, with the rise of Zika, people have started wondering aloud once again why we don’t just get rid of the biting bugs.     Whenever you talk about eliminating a whole species, or, in the case of every mosquito, a few thousand species, the question of ecology looms. How important are these animals? What relies on them for food or protection or pollination? According to Cameron Webb, a medical entomologist with the University of Sydney, we still don’t know very much about the role mosquitoes play in the ecosystem.    Unsurprisingly, most of the research that’s done on mosquitoes is done on either how to kill them, or what diseases they might give us. There’s not a ton of work done on their importance in the environment. So we don’t know what might happen to the ecosystem if we were to eliminate them entirely.     What we do know is that we’ve been fighting mosquitoes for a really long time. The CDC was actually founded in response to malaria. And Maryn McKenna, who you might remember from our episode on antibiotic resistance, came back for this episode to tell us about the history of trying to control these mosquito borne illnesses.     So how do we actually kill all these bugs? It won’t be easy. Mosquitoes are sneaky, particularly the species that transmit disease to humans. This future probably involves a combination of things: pesticides, land management, education, and genetic modification. Not on humans, like we talked about in episode 20 from last season. But of the mosquitoes themselves.    To explain how genetically modified mosquitos worked, we talked to Hayden Parry, the CEO of a company called Oxitec that developed and grows these modified insects. The basic premise behind them is to engineer male mosquitoes that can’t produce viable baby mosquitoes. These males mate with regular females, and their offspring all die, thus controlling the population.     All that and more in this week’s episode, so have a listen.  Learn more about your ad choices.

With constant news topping the headlines about the Zika virus, a synthetic biology company out of Oxford England, Oxitec, has been getting some good press. For over ten years now, Oxitec has been developing their genetically engineered mosquitos as a way to lower virus spreading mosquito populations.

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.
