Top New Science Podcasts: Pregnancy Risks Of Covid-19, Razor Blades & Hair

science-magazine-podcastsStaff 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.

Top New Science Podcasts: Covid-19 Vaccine Fears And Origin Controversies

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.

Top New Science Podcasts: How The Skin Stretches, Covid-19 Conferences And Pain Resistance Traits

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.

We take a look at some highlights from the Nature Briefing. This time we discuss a puzzling new insight into the expansion of the Universe, and an update to Plan S that will allow open-access research to be published in any journal. Nature News: Mystery over Universe’s expansion deepens with fresh dataNature News: Open-access Plan S to allow publishing in any journal

Top New Science Podcasts: Reopening Schools Amid Covid-19, Oil Processing

science-magazine-podcastsContributing 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 children 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 adults at schools are particularly important measures.

Also this week, Sarah talks with Kiristie 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.

Top New Science Podcasts: Exploring Graphene’s Superconductivity, Covid-19 In The Air & Lungs

Nature PodcastProbing the superconducting properties of graphene and a bacteria that can use manganese to grow. If you sandwich two sheets of graphene together and twist one in just the right way, it can gain some superconducting properties. Now, physicists have added another material to this sandwich which stabilises that superconductivity, a result that may complicate physicists’ understanding of magic angles.

Top New Science Podcasts: Megatrials For Covid-19 Treatment & Blood Benefits Of Exercise

science-magazine-podcastsContributing correspondent Kai Kupferschmidt talks with host Sarah Crespi about the success of a fast moving megatrial for coronavirus treatments. The United Kingdom’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. 

Kupferschmidt discusses why such a large study is necessary and why other large drug trials like the World Health Organization’s Solidarity trial are lagging behind. Also this week, producer Meagan Cantwell talks with Saul Villeda, a professor in the Department of Anatomy at the 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.

New Science Podcasts: Satellite Navigation, World Wide Web & Neolithic Genomics (BBC)

BBC Radio 4BBC Radio 4 ‘Inside Science’ talks about satellite navigation in the UK; the science of the World Wide Web and Neolithic genomics.

Is the UK losing its way when it comes to satellite navigation? There’s GPS from the US, but other countries and regions, including Russia, China, India and Japan, either have, or are building, satellite navigation systems of their own. The EU has Galileo, but with Brexit, Britain is no longer involved. The Government has announced that it’s just acquired a satellite technology company called OneWeb. It’s primary role is enhanced broadband, but there’s talk of adding in a navigation function to the constellation of satellites. But how feasible will that be?

In an era of cyber-crime, misinformation, disinformation, state-sponsored attacks on rival countries’ infrastructure, government-imposed internet shutdowns in places like Eritrea and Kashmir, the World Wide Web is an increasingly dark and troubled place. Making sense of how the internet has changed from the democratic, sharing, open platform it was designed to be, and predicting what’s next, are the web scientists. Professor Dame Wendy Hall, Regius Professor of Computer Science at the University of Southampton, and a co-founder of the whole field of web science, is hosting an online, annual conference this week. The theme this year is ‘Making the web human-centric’.

Communal burial sites tend to suggest an egalitarian society, where everyone is considered equal. And this is what we expected the Neolithic societies that spread across Europe with the birth of agriculture around 6000 years ago would be. But DNA evidence from a single human, NG10, buried in 3200 B.C.E in the vast tomb of Newgrange, 25 miles north of Dublin, in Ireland, shows very strong inbreeding. Couple this with the fact the body was buried and not cremated and placed in a highly adorned chamber. Does this indicate an elite ruling class where marrying one’s close kin was the order of the day? Dr. Lara Cassidy, palaeogeneticist at Trinity College Dublin, decoded NG10’s DNA and she tells Adam Rutherford the story.
