This is the Sarawak portion of Malaysia. A man in his late 30s is admitted to the hospital in December with daily fevers that last for several hours and shaking chills. He had previously been healthy with no medical problems. He lives in the city and works in an office, however, in the few weeks prior to getting admitted he was visiting the jungle. Apparently not too far outside of Kuching, one can go up into the jungle and see Orangutans. He had gone into the jungle but this was 2 weeks prior to the onset of symptoms. Since then he reports no unusual exposures. He lives with his wife and children and they are all healthy. A few days prior to admission he noted fever, chills, and a headache. He is a little nauseated but no vomiting. On exam he has a fast heart rate and appears ill. His respiratory rate is increased and he is not febrile on admission but later does have fever.  No enlargement of the liver or spleen on exam. Otherwise unremarkable. His labs are notable for low white blood cells, anemia, and a platelet count of less than 50k per microL. His coagulation studies are abnormal, serum creatinine is elevated, and there is elevation of his serum aminotransferases.

This week we discuss vectors in a hotter world.   Vector-borne diseases, which are transmitted by hematophagous arthropods such as mosquitoes, ticks, and sandflies, pose a significant burden on global public health. These diseases disproportionately affect populations in tropical and subtropical regions, where environmental conditions favor the survival and proliferation of vectors. Given that vectors are ectothermic organisms, their life cycles, reproduction, survival rates, and geographic distribution are heavily influenced by climate variables such as temperature, rainfall, and humidity. Consequently, changes in climate patterns can have profound effects on the transmission dynamics of vector-borne diseases, altering their geographic spread and intensity. Rising global temperatures have led to the expansion of vector habitats into previously unsuitable regions, including temperate zones. Warmer climates accelerate the development of many vectors and pathogens, reducing the extrinsic incubation period of viruses such as dengue, Zika, and chikungunya. Additionally, increased temperatures can extend the breeding season of mosquitoes like Aedes aegypti and Anopheles species, enhancing their capacity to transmit diseases such as malaria. Conversely, extreme heat events may reduce vector survival in some regions, leading to localized declines in transmission. ​Changes in precipitation patterns also play a crucial role in shaping vector distribution. Heavy rainfall events can create new breeding sites for mosquitoes by increasing the availability of stagnant water, while drought conditions may drive vectors closer to human settlements in search of water sources. In particular, shifts in rainfall patterns have been linked to outbreaks of malaria, dengue, and West Nile virus in various parts of the world. Increased humidity can further facilitate the survival of certain pathogens within vectors, enhancing their ability to transmit infections. Beyond climate variables, other anthropogenic factors contribute to the spread of vector-borne diseases. Land use changes, such as deforestation and urbanization, have disrupted natural ecosystems, bringing vectors and humans into closer contact. For example, deforestation in the Amazon has been associated with increased malaria transmission due to the creation of new breeding sites for Anopheles mosquitoes. Similarly, expanding urban populations with inadequate water management systems provide ideal conditions for the proliferation of Aedes mosquitoes, driving the rise in dengue and chikungunya cases. Globalization and human mobility further compound the issue by facilitating the movement of infected individuals and vectors across borders. Increased travel and trade have contributed to the introduction and establishment of vector-borne diseases in regions where they were previously rare. For instance, the spread of Aedes albopictus, a competent vector for dengue and chikungunya, has been linked to international trade in used tires and lucky bamboo plants, which serve as breeding grounds during transport. The multifaceted relationship between climate change and vector-borne diseases presents a challenge for public health interventions. While climate factors influence vector dynamics, their impact is often modulated by socio-economic conditions, infrastructure, and public health responses. To mitigate the growing threat of vector-borne diseases, an integrated approach is necessary—combining climate adaptation strategies, vector control measures, surveillance programs, and community engagement. Recent research underscores the importance of predictive modeling to anticipate outbreaks and inform public health policies. Advances in remote sensing, artificial intelligence, and climate modeling are enabling researchers to identify high-risk areas and implement targeted interventions. Strengthening early warning systems and investing in sustainable vector control strategies, such as genetically modified mosquitoes and Wolbachia-infected mosquito programs, offer promising avenues for reducing disease transmission. In conclusion, while climate change is reshaping the global landscape of vector-borne diseases, its effects are complex and intertwined with other environmental and societal factors. Understanding these dynamics is crucial for developing proactive strategies to mitigate the risks associated with the redistribution of vectors and the spread of diseases worldwide. By integrating climate science, epidemiology, and public health measures, we can better prepare for emerging threats and protect vulnerable populations from the growing impact of vector-borne diseases.  

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?

By 2026, Wolbachia-carrying mosquitoes released by the National Environment Agency (NEA) will be buzzing through 50 per cent of all households across the island. That's part of NEA's efforts to expand Project Wolbachia, to provide coverage to areas at risk of large dengue outbreaks. Under the project, which was first introduced in 2016, male Aedes aegypti mosquitoes that carry the Wolbachia bacteria are released to mate with the female Aedes mosquitoes. The eggs that are produced do not hatch. On this episode of Morning Shot, Ng Lee Ching, Group Director of the Environmental Health Institute, NEA shares her insights on how effective the project has been so far, how recent weather changes might affect mosquito breeding cycles, and what the public should look out for.

GDP Script/ Top Stories for October 16th Publish Date:  October 16th   From the BG AD Group Studio Welcome to the Gwinnett Daily Post Podcast. Today is Wednesday, October 16th and Happy 66th Birthday to actor Tim Robbins ***10.16.24 – BIRTHDAY – TIM ROBBINS*** I'm Keith Ippolito and here are your top stories presented by KIA Mall of Georgia. 1.       Celebration To Honor Mall of Georgia's 25th Anniversary 2.       Georgia Gwinnett College discovers bacteria in Joro spider 3.       Gwinnett/Walton Habitat for Humanity Celebrates 10 Years of Impact Plus, Leah McGrath from Ingles Markets on fiber. All of this and more is coming up on the Gwinnett Daily Post podcast, and if you are looking for community news, we encourage you to listen and subscribe! Break 1: KIA MOG (07.14.22 KIA MOG)   STORY 1:  Celebration To Honor Mall of Georgia's 25th Anniversary The Mall of Georgia is celebrating its 25th anniversary with a party featuring vendors, live music, and a ribbon-cutting ceremony on Thursday from 5 p.m. to 8 p.m. The event will include city representatives and Gwinnett Chamber members. Since opening in 1999, the mall has been a popular shopping and dining destination, known for its unique shopping village and historic murals. It continues to expand with new businesses. Erika Bridges, the mall's marketing director, expressed gratitude for community support. Owned by Simon Property Group, the mall remains a key part of regional growth. STORY 2:  Georgia Gwinnett College discovers bacteria in Joro spider Joro spiders, first spotted in Georgia a decade ago after arriving from Asia, are most visible in September and lay eggs by mid-October. Dr. James Russell and student Nicholas Mizera from Georgia Gwinnett College discovered that Joro spiders are infected with Wolbachia, a common bacteria in insects. While Joro spiders can't transmit Wolbachia to humans, the bacteria may cause reproductive barriers in spiders, potentially useful for population control. This concept could extend to other insects like mosquitoes. Mizera's research experience confirmed his passion for biology, and he plans to pursue a doctorate. Russell and Mizera are preparing a paper on their findings. STORY 3: Gwinnett/Walton Habitat for Humanity Celebrates 10 Years of Impact Gwinnett/Walton Habitat for Humanity is celebrating the 10th anniversary of its "A Brush with Kindness" program, which provides critical home repairs and modifications for income-eligible homeowners in Gwinnett and Walton counties. Executive Director Brent Bohanan credits the program's success to community partnerships and volunteer efforts. Over the past decade, the initiative has restored over 300 homes, improving safety and living conditions for senior citizens, veterans, and families in need. The program focuses on essential repairs like exterior painting and accessibility improvements, enhancing community strength and preserving homeownership. For more details, visit habitatgwinnett.org.

Atlanta Falcons owner Arthur Blank expressed gratitude for the honor, highlighting the stadium's capability to host major events. This will be Atlanta's fourth Super Bowl, with previous games held in 1994, 2000, and 2019. The successful bid was led by the Atlanta Sports Council and various local organizations. Atlanta is also set to host other major events, including the College Football Playoff National Championship and FIFA World Cup. Georgia Governor Brian Kemp praised the decision, emphasizing Atlanta's readiness to host large-scale events. STORY 5:   Gwinnett Issues Bonds to Buy Mall Macy's Stores. What We Know  Gwinnett County is advancing its redevelopment plans for the former Gwinnett Place Mall by purchasing the Macy's department and furniture stores for $16.5 million, with the deal closing in November. The county issued bonds at a 4.7% interest rate, raising $17.2 million, and received a AAA bond rating, which Chairwoman Nicole Love Hendrickson highlighted as beneficial for taxpayers. This acquisition adds 23 acres to the county's holdings, totaling 76 acres, and enhances redevelopment flexibility. The "Global Villages" concept will guide the mall's transformation, with most of it being demolished, except for existing anchors. Development partner proposals are expected in early 2025.

El dengue se está convirtiendo en un grave problema en América Latina y el Caribe, según advirtió la Organización Panamericana de la Salud (OPS). Sin embargo, gracias a la modificación biológica de los mosquitos transmisores de esta enfermedad, el World Mosquito Program está consiguiendo reducir los casos a pasos agigantados en algunas regiones del mundo. Tras años de duros esfuerzos, el World Mosquito Program redujo los casos de dengue en un 95 % en la región de Antioquia, Colombia. ¿Cómo? Criando y más tarde liberando mosquitos nacidos con la bacteria Wolbachia, que "impide la transmisión" de esta enfermedad endémica de zonas tropicales, que provoca dolores de cabeza, vómitos y, en algunos casos, hasta la muerte.A pesar de estos resultados prometedores, la OPS advierte que este año América Latina y el Caribe vivirán su "peor temporada de dengue" con unos 9,3 millones de casos y al menos 4.500 muertes entre enero y junio debido al cambio climático, ausencia de servicios de agua y sobrepoblación.Nelson Grisales, responsable de este proyecto en Medellín, nos explica que el primer paso para resolver el problema es concienciar a los Gobiernos:Cuando se empiece a entender y aceptar que los métodos de control biológico, particularmente este que es un método natural donde no hay ninguna manipulación, los gobiernos van a comenzar a requerir. Esa voluntad de entendimiento es algo que lleva tiempo para algo tan revolucionario, pero creo que vamos por muy buen camino.Otro factor que impide la implementación de este sistema de prevención es la falta de recursos para adoptarlo en países tropicales y subtropicales en vías de desarrollo. "Todos sabemos que los recursos disponibles para salud pública y enfermedades como dengue, que no necesariamente son muy letales, son enfermedades olvidadas", afirmó Morales, quien aseguró que estas naciones "no disponen de mucho presupuesto" para poder controlarlas.Por ello, el especialista destacó la importancia de "la cooperación internacional y los donantes" para poder apoyar el trabajo que pueden hacer los gobiernos, a la vez que estos también pueden asignar o reasignar algunos recursos para que esto se lleve a cabo. El riesgo de la desinformaciónPor último, el experto señala la desinformación como un elemento que impide la integración del programa en algunas regiones. Por ejemplo,  en septiembre del año pasado, un puñado de personas protestaron frente a su laboratorio argumentado que Bill Gates, uno de los financiadores del proyecto, libera chips a través de los mosquitos para controlar las mentes."La desinformación, en este momento, es un problema a nivel de salud pública: las campañas antivacunas, antimedicamentos, antimedicina en términos generales, son grandes y afectan a todos los países", sostuvo el responsable. A su juicio, esto genera "un entendimiento equivocado" de muchos factores, que por más que resulten intuitivos o normales, con una narrativa errada pueden manejar campañas de desinformación.Leer tambiénPerú apuesta por un plan piloto de vacunación para combatir el denguePuede que todos estos obstáculos retrasen la implementación del proyecto en algunos países, pero el experto está convencido de que pronto el World Mosquito Program llegará a ser una medida de salud pública. Ya que asegura que su misión no terminará hasta erradicar el dengue.

Perú anunció que aplicará estas vacunas a los menores de entre 6 y 16 años de la zona de Piura, en el noroeste del país, la más afectada. El plan piloto de vacunación contra el dengue se hará con la vacuna del laboratorio japonés Takeda. Se trata de un esquema de dos dosis, eficaz desde la primera, que se hará en intervalos de tres meses en la población objetiva, según anunció el ministerio de Salud peruano. Si bien se trata de una noticia esperanzadora, el especialista peruano en enfermedades infecciosas y tropicales, Eduardo Gotuzzo, resaltó que la vacunación ha de ser parte de una política más amplia de lucha contra la enfermedad.  El dengue hoy en día en América Latina es la enfermedad más notable que hay- Eduardo Gotuzzo, especialista en enfermedades infecciosas y tropicales“El control lamentablemente de dengue es un tema complejo que no se puede resolver fácilmente, si es que no hay toda una política múltiple que incluye que la población misma participe en erradicar las fuentes donde se reproducen los mosquitos que el ministerio de Salud con el ministerio de Agricultura procure eliminar, utilizarlo adecuadamente los insecticidas, entonces las vacunas es un elemento adicional”, afirma Gotuzzo. Leer tambiénArgentina: El dengue hace estragos y el Estado, ausenteEste programa se aplicará a niños de entre 6 y 16 años por ser los más expuestos a la mortalidad, junto con los mayores de 60 años con comorbilidades.

Selon Gotson Pierre, directeur de l'agence Alterpresse, la vie à Port-au-Prince tournait au ralenti avec beaucoup de tirs entendus hier lundi à Tabarre. Gotson Pierre parle de l'angoisse et de la panique des habitants. D'ailleurs les violences dans le pays ont atteint des niveaux jamais vus : 5 000 personnes ont été tuées en 2023. Il n'y a jamais eu autant de meurtres depuis 30 ans. La population civile utilisée comme bouclier humainAlterpresse relaye l'appel du professeur de droit international, James Boyard qui met en garde contre une éventuelle utilisation de civils comme boucliers humains par les gangs armés en Haïti. Selon James Boyard, « l'appel lancé par les gangs à la population civile de regagner leur maison n'est qu'une stratégie leur permettant de sanctuariser leur territoire, grâce à la présence d'une masse critique de citoyens pouvant être utilisée comme boucliers humains en cas d'attaques des forces publiques », explique-t-il sur X.Le trafic d'armes vers Haïti, un fléau difficile à endiguerMalgré un embargo décrété par l'ONU, les armes continuent à affluer en Haïti. C'est un article à lire dans le Washington Post. Haïti ne produit ni armes ni munitions, tout est importé. Selon le journal, les fusils semi-automatiques « utilisés dans les fusillades de masse aux États-Unis servent aussi à terroriser la population haïtienne ». Aucune donnée officielle quant au trafic mais 85 pour cent des armes saisies par les autorités haïtiennes proviennent des États-Unis. Il faut dire qu'Haïti n'est pas le seul pays caribéen à être inondé par des fusils, mitraillettes et munitions fabriquées aux États-Unis. L'année dernière, plusieurs gouvernements de la région ont poussé un cri d'alarme, demandant aux États-Unis d'empêcher le trafic d'armes vers leurs pays, un trafic que les dirigeants considèrent comme une menace pour la démocratie. Côté américain, on fait savoir que c'est extrêmement difficile de contrôler les cargos qui partent de Miami à destination d'Haïti. Les armes sont cachées dans d'énormes containers qui contiennent toutes sortes de marchandises que des Haïtiens de Miami envoient à leurs familles. Selon le responsable de la sécurité intérieure de l'État de Miami, cela prendrait des semaines pour ses agents de fouiller les cargos.Crise entre l'Équateur et le Mexique : les responsabilités sont partagéesLe président équatorien Daniel Noboa, dans une lettre, s'est directement adressé aux Mexicains afin de leur expliquer sa décision de forcer l'entrée de l'ambassade mexicaine afin d'arrêter l'ancien vice-président Jorge Glas. Une décision « exceptionnelle » selon lui, motivée par la volonté de protéger « la sécurité nationale ». Daniel Noboa, dans la même lettre, dit que qu'il sera « toujours disposé à résoudre les différends, mais que la justice n'est pas négociable et que nous ne protégerons jamais les criminels qui ont fait du mal aux Mexicains ». C'est à lire dans le journal équatorien La Hora. Le même journal estime d'ailleurs que les responsabilités de cette crise sont partagées. Selon La Hora, le gouvernement mexicain d'Andrés Manuel López Obrador a violé le principe de « non-intervention » en octroyant l'asile politique à un Équatorien condamné pour corruption.

En Brasil se está usando el médoto Wolbachia para combatir el Dengue. ¿En qué consiste? El Dr. Elmer Huerta nos explica.

Antropoceno es un término que en los últimos 20 años se ha venido utilizando con profusión en libros, artículos y medios de comunicación. Fue creado en la década de 1980 por el biólogo estadounidense Eugene Stoermer para designar un nuevo intervalo de tiempo geológico caracterizado por el impacto de las actividades humanas en el planeta, aunque sería el premio nobel de química Paul Crutzen quien lo popularizó en el año 2.000. Ahora, un panel de expertos de la Unión Internacional de Ciencias Geológicas ha rechazado la propuesta para declararlo oficialmente como el inicio de una época geológica. Hemos entrevistado a Juan Carlos Gutiérrez Marco, investigador del Instituto de Geociencias. José Antonio López Guerrero nos ha comentado un proyecto de la Fundación Bill y Melinda Gates para infestar a los mosquitos Aedes con una bacteria del género Wolbachia que impide la transmisión de virus como el Zika, el Dengue o la Fiebre amarilla. Eva Rodríguez nos ha informado de un estudio de la universidad de Princeton que ha constatado que la mayoría de los mamíferos machos no son más grandes que las hembras; y de cómo el cerebro procesa el miedo. Con Carlos Briones hemos celebrado el centenario de la publicación del libro "El origen de la vida", del bioquímico ruso Alexander Oparin, la primera obra sobre este tema tan apasionante. Javier Cacho participa en la expedición "Into the Aurora II" y nos ha contado como intentarán grabar auroras boreales en Finlandia, a 30 km de altitud, con la ayuda de un globo aerostático. Escuchar audio

Mosquito-borne diseases are one of the greatest global health threats, infecting around 700 million people every year with Zika virus, dengue fever, malaria and yellow fever — which can all be deadly if left untreated. Unfortunately, the mosquito population is not slowing down, and factors like climate change and increased global travel are broadening the mosquito's range. The effort to stop the mosquito is not an easy task; insecticides and vaccines can't completely stop the spread of these diseases. But instead of trying to kill mosquitoes, one nonprofit is taking a unique approach.Scientist Scott O'Neill is founder and CEO of the World Mosquito Program, a nonprofit group with the goal of eliminating mosquito-borne diseases. The program is implementing a new method of inoculating the wild population of mosquitoes with a bacteria called Wolbachia, which is resistant to diseases. So far, the program has been rolled out in countries like Brazil, Colombia, Indonesia, Australia and Mexico – and has already seen success in reducing rates of disease.Link to the advertised Chicago Booth Review Podcast: https://www.chicagobooth.edu/review/podcast?source=cbr-sn-bbr-camp:podcast24-20240307

Wolbachia se creía que era un microorganismo de los insectos con pocas consecuencias para la salud humana. Esa noción se ha desvanecido en los últimos años al darse cuenta de que Wolbachia podía impedir que los mosquitos transmitieran a las personas virus causantes de enfermedades como el dengue, el Zika, el chikungunya y la fiebre amarilla.

African swine fever has now reached Southeast Asia.This part of the world has high diversity in wild pigs, some of which are endemic to their native islands. In Borneo, pigs are a hugely important food source for indigenous populations, and are a vital prey species for many big cats. In some regions, the pig populations have now dropped by 90 to 100 per cent due to swine fever. Conservationist Dr Erik Meijaard explains what this could mean for Borneo. Sticking with diseases, the World Mosquito Program breeds mosquitoes infected with Wolbachia. Why? Because mosquitoes infected with this bacteria are unable to become carriers of dengue, Zika and other mosquito-borne diseases. Dr Scott O'Neill of the World Mosquito Program talks about their latest research and the massive mosquito factory they're building in Brazil this year. Finally this week, Dr Nitzan Gonen discusses her new study, where mouse testes organoids have been grown in the lab. She tells us about the potential applications for this research.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Dengue rates drop 77-95% after release of bacteria-infected mosquitoes in Colombia, published by SiebeRozendal on November 7, 2023 on The Effective Altruism Forum. When infected with Wolbachia, the mosquitoes are much less likely to transmit diseases such as dengue and Zika, because the bacteria compete with these viruses. The insects also pass the bacteria on to their offspring. Researchers hope that the modified mosquitoes will interbreed with the wild population wherever they are released, and that the number of mosquitoes with Wolbachia will eventually surpass that of mosquitoes without it. [...] When the scientists compared the incidence of dengue in fully treated areas with that in the same regions in the ten years before the intervention, they found that it had dropped by 95% in Bello and Medellín and by 97% in Itagüí. Since the project started, there hasn't been a large outbreak of dengue in the region. "They've had six years now with a sustained suppression of dengue," says Anders. "We're starting to see the real-world effect of Wolbachia." [...] The [World Mosquito Program] has conducted one [RCT] in Yogyakarta, Indonesia, in which mosquitoes were released in some areas of a city and the incidence of dengue was compared with that in areas that did not receive the insects. The results suggested that the technology could reduce the incidence of dengue by 77%. The organization is now conducting a similar one in Belo Horizonte, Brazil. The RCT: https://pubmed.ncbi.nlm.nih.gov/34107180/ Despite the positive results, Wolbachia mosquitoes have not yet been officially endorsed by the World Health Organization (WHO). The technology awaits an evaluation by the WHO's Vector Control Advisory Group.

En su colaboración con Guillermina Gómora en ausencia de Manuel López San Martín para MVS Noticias, la periodista Luciana Wainer habló sobre combatir el dengue con mosquitos. “Están agarrando a los mosquitos que son portadores de arbovirus y les están inyectando la bacteria Wolbachia y posteriormente una liberación masiva de mosquitos con el fin de disminuir la posibilidad de que el zancudo transmita la enfermedad”, mencionó. De acuerdo con la organización Médicos sin Fronteras, “actualmente no se dispone de tratamientos específicos y aún no se han producido vacunas que proporcionen suficiente protección contra la infección”. En la página web de la organización se establece que “el método Wolbachia del World Mosquito Program es seguro para las personas y el medio ambiente y se ha implementado con éxito en más de 12 países, llegando a unos 10 millones de personas. Las pruebas demuestran que la transmisión del virus se reduce significativamente en las zonas donde se mantiene un alto nivel de Wolbachia”. See omnystudio.com/listener for privacy information.

Dr. Scott O'Neill (PhD, FAA, FAAAS) is Founder of the World Mosquito Program ( https://www.worldmosquitoprogram.org/en/work/about-us/team/scott-oneill ) and Professor at Monash University ( https://lens.monash.edu/@scott-oneill ), where he leads a large international research collaboration (formerly known as Eliminate Dengue), which is focused on developing the Wolbachia bacteria as a novel method to block the transmission of dengue fever and other mosquito-transmitted viral diseases, such as Zika and chikungunya. This global, not-for-profit program is currently conducting field trials of the Wolbachia method in multiple countries, in areas where these diseases are endemic, working closely with communities, local health organizations and governments to implement its self-sustaining method through controlled releases. Dr. O'Neill has spent his academic career at the University of Illinois, Yale University, the University of Queensland and Monash, where he was previously the dean of the Faculty of Science. Dr. O'Neill is internationally recognized for his contributions to the field of insect symbiosis and the way the intimate bacterial associations of invertebrates are ubiquitous and can generate major effects on the reproductive physiology, developmental biology and ecology of the insects they infect. His work has made major contributions to understanding how insect symbionts exert their effects and the consequences for infected hosts. Support the show

Did you know that one million residents across Singapore are now covered under Project Wolbachia? This comes after the expansion of the number of sites covered under the initiative as part of efforts to stem the transmission of dengue fever. For those who aren't familiar with the initiative, it's a pilot using male mosquitoes infected with the Wolbachia bacteria to suppress the population of Aedes aegypti mosquitoes.  As we enter warmer months of the year when dengue transmission is typically higher, dengue expert, Associate Professor Ng Lee Ching, Group Director of the Environmental Health Institute at National Environment Agency elaborates on challenges of the project and how effective it has been in curbing dengue cases in Singapore so far.  Presented by: Lynlee Foo This podcast is produced and edited by Yeo Kai Ting (ykaiting@sph.com.sg) See omnystudio.com/listener for privacy information.

In this episode, we are going to celebrate World Malaria Day with our co-host and guests. This year's theme is Time to Deliver Zero Malaria, and it is focused on investing, innovating, and implementing tools that are available today and innovating for future tools. WHO calls to action include prioritising funding for the most marginalised and hard to reach populations who are less able to access services and are the hardest hit when it comes to becoming ill from malaria. To help us understand more, we have co-host, Dr. Hellen Barsosio, who is a medical Kenyan doctor who has been investigating risk factors, tools, and interventions to prevent adverse birth outcomes, and more recently research on preventing malaria in pregnancy. She is in her final year of her PhD at the Liverpool School of Tropical Medicine under the Department of Clinical Science, where her PhD focuses on new drugs to prevent malaria in pregnancy. The WHO also calls for stepping up innovation for new vector control approaches, so we have two guests with us today to help us to understand what those are. We will be speaking to reader and Wolfson Fellow, Dr. Grant Hughes, and reader, Dr. Tony Nolan from the Vector Biology and Tropical Disease Biology Department at the Liverpool School of Tropical Medicine. Tony has led the development of genetic tools to better understand the biology of mosquitoes that transmit malaria, and this has led to the development of genetic approaches to control mosquito populations. This is to decrease the amount of malaria transmission. Tony is also using some of these tools to understand how insecticides work, and in particular, how mosquitoes can evolve resistance to insecticides. Grant is currently focusing on novel control strategies for arboviruses and malaria, and his overarching goal is to develop approaches which will either reduce mosquito numbers, or stop these mosquitoes transmitting the pathogens that make people ill. This episode features: Dr Hellen Barsosio - Clinical Research Scientist and section Head Maternal and New-born Health Studies, Malaria Program, KEMRI-CGHR Over the past 11 years, Hellen has been investigating risk factors, tools and interventions to prevent adverse birth outcomes, and more recently research on preventing malaria in pregnancy as one of the causes of adverse birth outcomes in malaria endemic areas. She trained in Kenya as a medical doctor, and did her post-graduate studies at the London School of Hygiene and Tropical Medicine and University of Oxford. She is in the final year of her PhD at Liverpool School of Tropical Medicine under the department of Clinical Science where her PhD work focuses on new drugs to prevent malaria in pregnancy. Dr Tony Nolan - Reader in Insect Genetics and Research Group Leader, Liverpool School of Tropical Medicine Tony has led the development of genetic tools to better understand the biology of mosquitoes that transmit malaria. This has led to the development of genetic approaches to control mosquito populations, in order to decrease the amount of malaria transmission. Tony is also using some of these genetic tools to understand how insecticides work and, in particular, how mosquitoes can evolve resistance to insecticides. Dr Grant Hughes - Reader and Royal Society Wolfson Fellow, Liverpool School of Tropical Medicine Grant has been investigating the use of microbes to control mosquito-borne diseases for over 15 years. After undertaking a PhD at the University of Queensland in Australia looking at microbial control of crop pests, Grant moved to the US to complete a post-doctoral fellowship at Johns Hopkins Bloomberg School of Public Health to examine how a bacteria called Wolbachia infected mosquitoes and interacted with Plasmodium parasites, the parasites that cause Malaria. After further work at Penn State University,...

We got the zany audio morsels, you already know. We got a riverside soliloquy about mortality and, you guessed it, quantum physics. And we got some salubrious and invigorating veggies for your brain vittles. Topics include the dystopian project out of friend-of-show DARPA called Insect Allies, which involves infecting bugs with synthetic viruses so they can then infect crops with synthetic viruses, because national security. What could possible go wrong? If Daddy DARPA does it, it MUST be safe, effective, necessary and totally cool!Also covered is the Gates Foundation and Wellcome Trust funded World Mosquito Project, which, you know, just infects mosquitos with Wolbachia bacteria that fucks with their reproductive systems, and then releases them en masse into wild ecosystems around S. America, S.E. Asia, the Pacific Islands and Florida. I'm sure there won't be any hellish unforeseen blowback from this chicanery; it'll probably work exactly as intended and everything will be totally chill.Lastly, I feature a recent Yak Fest w/ Dr. Sylvie where we discuss the oligarch billionaires poised to profit off of "Big Green" amidst the global climate "action" mania.

Avian malaria has devastated native Hawaiian birds called honeycreepers. And now, climate change is allowing the mosquitoes that carry the disease to spread into the last mountain refuges of highly endangered honeycreepers on the island of Kauai. However, there's hope that a new tool could eradicate the disease. Researchers are raising mosquitoes in the lab infected with Wolbachia, a bacterium that makes them infertile. When these males mate with wild female mosquitos, they fail to reproduce. While they wait for the mosquito solution to become available, biologists are carrying out last-ditch efforts to keep the species alive in captivity.More info and transcript at BirdNote.org. Want more BirdNote?

Today we are joined by Joanne Odden. Joanne studies insect symbiosis and is a tenured Associate Professor of biology at Pacific University. As a teacher scholar, her passion is to examine tiny things (e.g. DNA and bacteria) which drive changes in insects over time. Joanne began her studies at University of Wisconsin Oshkosh, where she received a B.S. in Microbiology and worked at a campus science outreach program. This spurred her inspiration to teach science. She studied the neural development of fruit fly embryos at University of Oregon, where she earned her Ph.D. in Molecular Biology. During her first faculty position at Metropolitan State College of Denver, she developed an undergraduate research program in insect bacterial symbiosis. Joanne earned a Golden Key award for Excellence in Teaching in 2013. Currently, at Pacific University, she studies the evolution of symbiosis. Her model system is the charismatic association of Wolbachia bacteria within carabid beetles. She combines her interests in biology, travel and education by leading travel courses for undergraduate students to the Galapagos Islands and Tahiti.Show Notes:Joanne Odden, PhD | Pacific UniversitySymbiosis: The Art of Living Together | National GeographicExploitation and Cooperation by Cleaner Wrasse | University of Miami Shark ResearchEpigenetic Memory | NatureWolbachia | ScienceDirectFacts about tardigrades | LiveScienceGenus Bembidion | BugGuideI Contain Multitudes: The Microbes Within Us and a Grander View of Life by Ed Young | AmazonMiller Moths | Colorado State University Extension Service Consuming Creepy-Crawlies | TerroTiny animals survive exposure to space | European Space AgencyHow the Zombie Fungus Takes Over Ants' Bodies to Control Their Minds | The Atlantic

How does one of the most diverse groups on the planet, the ants, interact with the extremely diverse group of microbes that live on and inside them? On this episode, we talk to Corrie Moreau, a professor of entomology at Cornell University, about the diversity and influence of microbes in ants. For Corrie, these microbes are a sort of internal rainforest, whose presence directly impacts the lives of the ants who carry them. Many ant-microbe relationships have evolved over millions of years, resulting in specialized interactions – from fungus-farming in leaf cutter ants, to insect mind control by the Ophiocordyceps fungus, to distortion of insect reproduction by Wolbachia bacteria. We also chat with Corrie about science communication, and how making biology a welcoming and diverse place will inspire the next generation of researchers and promote greater trust in science by the public.

I've received reports of large migrations of whiteflies recently in the landscape, from Dallas, Austin and even east Texas regions. It's not uncommon to see large clouds of whiteflies when cotton is 'defoliated' in preparation for harvest; however, whiteflies often need some time to get used to their new plant host (acclimation). Changes in endosymbionts, bacteria found inside the insect that commonly have a mutualistic positive relationship with the insect, are a potential explanation for host shift acclimation. For fun, we also talk about the diabolical ironclad beetle and it's incredibly resilient properties that make engineers interested enough to study. Some references: Asplen, M. K., N. Bano, C. M.
