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.
