First up this week, Senior Correspondent Daniel Clery talks with host Sarah Crespi about how Breakthrough Listen—a privately funded initiative that aims to spend $100 million over 10 years to find extraterrestrial intelligent life—has changed the hunt for alien intelligence-link.  And as part of a special issue on the Genotype-Tissue Expression  (GTEx) Project, Brandon Pierce, a professor in the Departments of Public Health Sciences and Human Genetics at the University of Chicago, joins Sarah to discuss his group’s work on variation in the protective caps at the end of our chromosomes. The gradual shortening of these caps, also known as telomeres, has been associated with aging.  Read more from the GTEx special issue. This week’s episode was produced with help from Podigy.

First up this week, Contributing Correspondent Kai Kupferschmidt talks with host Sarah Crespi about rising numbers of coronavirus cases in Europe. Will what we’ve learned this summer about how the virus is transmitted and treated help prevent a second peak? Read all of our coronavirus news coverage.  And as part of a special issue on democracy, Rohini Pande, a professor in the department of economics at Yale University, joins Sarah to discuss her review that asks the question: Can democracy work for poor people?

Staff Writer Paul Voosen talks with host Sarah Crespi about how Arctic sea ice is under attack from above and below—not only from warming air, but also dangerous hot blobs of ocean water. Next, Damien Fordham, a professor and global change ecologist at the University of Adelaide, talks about how new tools for digging into the past are helping catalog what happened to biodiversity and ecosystems during different climate change scenarios in the past. These findings can help predict the fate of modern ecosystems under today’s human-induced climate change. And in our books segment, Kiki Sanford talks with author Carl Bergstrom about his new book: Calling Bullshit: The Art of Skepticism in a Data-Driven World.

First up this week, Staff Writer Erik Stokstad joins host Sarah Crespi to talk about how wildlife biologists are taking advantage of humanity’s sudden lull. Scientists are launching studies of everything from sea turtles on suddenly quiet beaches to noise-averse birds living near airports to see how animal behavior changes when people are a little less obtrusive. Read all of our coronavirus coverage here. Next, as part of our special issue on mud—yes, wet dirt— Senior Correspondent Elizabeth Pennisi talks about her story on electric microbes that were first found in mud and are now found pretty much everywhere. Why do bacteria need to move electrons around and what does it mean that they do it all over the planet? This week’s episode was produced with help from Podigy. Listen to previous podcasts.

Staff Writer Robert Service talks with host Sarah Crespi about a different approach to COVID-19 testing that might be useful in response to the high numbers of cases in the United States. To break chains of transmission and community spread, the new strategy would replace highly accurate but slow polymerase chain reaction (PCR) tests with cheaper, faster tests that are less accurate but can be administered frequently. Such tests cost between $1 and $3 compared with more than $100 for diagnostic PCR tests and give results in less than 30 minutes instead of days. Read all of our coronavirus coverage here. Also this week, Salma Mousa, a postdoctoral fellow at Stanford University, joins Sarah to talk about an experiment that added Muslim players to teams in a Christian soccer league in northern Iraq. The goal of the study was to see whether this type of social contact would change how the Christians—a threatened minority in the region—behaved toward Muslims, on and off the field.

Staff Writer Meredith Wadman joins host Sarah Crespi to discuss the risk of the novel coronavirus infection to pregnant women. Early data suggest expectant women are more likely to get severe forms of the infection and require hospitalization. Meredith describes how the biology of pregnancy—such as changes to the maternal immune system and added stress on the heart and lungs—might explain the harsher effects of the virus. Also this week, Sarah talks with Gianluca Roscioli about his experiments with commercial razor blades and real human hair. By using a scanning electron microscope, he was able to show how something relatively soft like hair is able to damage something 50 times harder like stainless steel.

Science Editor-in-Chief Holden Thorp joins host Sarah Crespi to discuss his editorial on preventing vaccine hesitancy during the coronavirus pandemic. Even before the current crisis, fear of vaccines had become a global problem, with the World Health Organization naming it as one of the top 10 worldwide health threats in 2019. Now, it seems increasingly possible that many people will refuse to get vaccinated. What can public health officials and researchers do to get ahead of this issue? Also this week, Sarah talks with Science Senior Correspondent Jon Cohen about his story on Chinese scientist Shi Zhengli, the bat researcher at the center of the COVID-19 origins controversy—and why she thinks President Donald Trump owes her an apology. Finally, Geert Van der Snickt, a professor in the conservation-restoration department at the University of Antwerp, talks with Sarah about his Science Advances paper on a new process for peering into the past of paintings. His team used a combination of techniques to look beneath an overpainting on the Ghent Altarpiece by Hubert and Jan Van Eyck—a pivotal piece that showed the potential of oil paints and even included an early example of painting from an aerial view.

Contributing Correspondent Dennis Normile talks about a long-term study involving the survivors of the Hiroshima and Nagasaki bombings. Seventy-five years after the United States dropped nuclear bombs on the two cities in Japan, survivors are still helping scientists learn about the effects of radiation exposure. Also this week, Sarah talks with Winnie Lau, senior manager for preventing ocean plastics at Pew Charitable Trusts about her group’s paper about what it would take to seriously fight the flow of plastics into the environment.  This week’s episode was produced with help from Podigy.

Contributing correspondent Gretchen Vogel talks about what can be learned from schools around the world that have reopened during the coronavirus pandemic. Unfortunately, few systematic studies have been done but observations of outbreaks in schools in places such as France or Israel do offer a few lessons for countries looking to send kids back to school soon. The United Kingdom and Germany have started studies of how the virus spreads in children and at school, but results are months away. In the meantime, Gretchen’s reporting suggests small class sizes, masks, and social distancing among the adults at school are particularly important measures.      Read all our coronavirus news coverage.   Also this week, Sarah talks with Kirstie Thompson, a Ph.D. student in the Georgia Institute of Technology’s Department of Chemistry and Biochemistry, about increasing the efficiency of petroleum processing. If all—or even some—petroleum processing goes heat free, it would mean big energy savings. Around the world, about 1% of all energy use goes to heating up petroleum in order to get useful things such as gas for cars or polymers for plastics. These days, this separation is done through distillation, heating and separating by boiling point. Kirstie describes a heat-free way of getting this separation—by using a special membrane instead.   Read a related Insight.   This week’s episode was produced with help from Podigy.   Listen to previous podcasts   About the Science Podcast   Download a transcript (PDF)  ++   [Image: Kurt Bauschardt/Flickr; Music: Jeffrey Cook]   Authors: Sarah Crespi; Gretchen Vogel Learn more about your ad choices.

Contributing correspondent Kai Kupferschmidt talks with host Sarah Crespi about the success of a fast moving megatrial for coronavirus treatments. The UK’s RECOVERY (Randomized Evaluation of COVID-19 Therapy) trial has enrolled more than 12,000 hospitalized coronavirus patients since early March and has released important recommendations that were quickly taken up by doctors and scientists around the world. Kai discusses why such a large study is necessary and why other large drug trials like the WHO’s SOLIDARITY trial are lagging behind. Also this week, producer Meagan Cantwell talks with Saul Villeda, a professor in the Department of Anatomy at University of California, San Francisco, about transferring the beneficial effects of exercise on the brain from an active mouse to a sedentary mouse by transferring their blood.
