As the coronavirus continues to spread around the globe, companies and academic labs are racing to develop a vaccine that would help society get back to normal. But there could also be costs to moving too quickly.

This week, Nature looks at a new method to grow hairy skin in a dish, and new research takes aim at the RNA world hypothesis.In this episode:
00:45 Hairy Skin
Researchers may have developed a way to make skin that can grow hair in the lab, paving the way for treatment of a variety of skin disorders, and perhaps even baldness. Research Article: Lee et al.; News and Views: Regenerative medicine could pave the way to treating baldness
08:56 Research Highlights
How mercury moved during the ‘Great Dying’, and the link between mobile phones and gender equality. Research Highlight: Giant eruptions belched toxic metal during the ‘Great Dying’; Research Article: Rotondi et al.
11:21 Does DNA predate life?
The RNA world hypothesis posits that RNA formed spontaneously leading eventually to life. Now new research suggests that RNA and DNA formed together, before life. Research Article: Xu et al.; News and Views: How DNA and RNA subunits might have formed to make the first genetic alphabet

A selection of three essential articles read aloud from the latest issue of The Economist. This week, how the world’s most powerful country is handling covid-19, China’s decision to impose a security law on Hong Kong threatens a broader reckoning (10:04). And why mercenaries are still hired by African governments (18:30).
Syndicated columnist Mark Shields and New York Times columnist David Brooks join Judy Woodruff to discuss the latest political news, including former Vice President Joe Biden’s comments on the death of George Floyd and what action it should prompt, President Trump’s approach toward Twitter and truth and the milestone of 100,000 American deaths from COVID-19.
President Trump’s preferred coronavirus treatment is the focus of a new study suggesting it could cause more harm than good, but not everybody agrees. We discuss the fallout as trials around the world are paused and countries diverge over policy advice.
12:12 Are we rushing science?
Coronavirus papers are being published extremely quickly, while normally healthy scientific debate is being blown up in the world’s press. Is there a balancing act between timely research and accurate messaging?
18:49 One good thing
Our hosts pick out things that have made them smile in the last week, including hedgerow brews and a trip into the past using AI.

First up this week, Staff Writer Jennifer Couzin-Frankel talks with host Sarah Crespi about a rare inflammatory response in children that has appeared in a number of COVID-19 hot spots. Next, Julian Dowdeswell, director of the Scott Polar Research Institute and professor of physical geography at the University of Cambridge, talks with producer Meagan Cantwell about tracing the retreat of Antarctica’s glaciers by examining the ocean floor. Finally, Kiki Sanford interviews author Danny Dorling about his new book, Slowdown: The End of the Great Acceleration―and Why It’s Good for the Planet, the Economy, and Our Lives.

What do these writers have in common? They were all members of the Shakespeare and Company lending library.
In 1919, an American woman named Sylvia Beach opened Shakespeare and Company, an English-language bookshop and lending library in Paris. Almost immediately, it became the home away from home for a community of expatriate writers and artists now known as the Lost Generation. In 1922, she published James Joyce’s Ulysses under the Shakespeare and Company imprint, a feat that made her—and her bookshop and lending library—famous around the world. In the 1930s, she increasingly catered to French intellectuals, supplying English-language publications from the recently rediscovered Moby Dick to the latest issues of The New Yorker. In 1941, she preemptively closed Shakespeare and Company after refusing to sell her last copy of Joyce’s Finnegans Wake to a Nazi officer.
The Shakespeare and Company Project uses sources from the Beach Papers at Princeton University to reveal what the lending library members read and where they lived. The Project is a work-in-progress, but you can begin to explore now. Search and browse the lending library members and books. Read about joining the lending library. Download a preliminary export of Project data. In the coming months, check back for new features and essays.
