These two photos, taken in 2014 by scientist Eddie Holmes, show raccoon dogs and unknown birds caged in the Huanan Seafood Wholesale Market. GPS coordinates of these images confirm that the animals were housed in the southwest corner of the market, where researchers found evidence of the coronavirus in January 2020.

In London to address a gene-editing summit last week, Victoria Gray took a break to visit Sir John Soane's Museum. In 2019, Gray became the first patient to be treated for sickle cell disease using CRISPR, an experimental gene-editing technique. She was invited to talk about her experiences at the Third International Summit on Human Genome Editing. Orlando Gili for NPR hide caption

Could de-extincting the dodo help struggling species?

As a leading expert on paleogenomics, Beth Shapiro has been hearing the same question ever since she started working on ancient DNA: "The only question that we consistently were asked was, how close are we to bringing a mammoth back to life?"

This Pi Day, how to BAKE pi(e) — and have mathematical fun

This March 14, Short Wave is celebrating pi ... and pie! We do that with the help of mathematician Eugenia Cheng, Scientist In Residence at the School of the Art Institute of Chicago and author of the book How to Bake Pi. We start with a recipe for clotted cream and end, deliciously, at how math is so much more expansive than grade school tests.

How well does a new Alzheimer's drug work for those most at risk?

A new drug for Alzheimer's disease, called lecanemab, got a lot of attention earlier this year for getting fast-tracked approval based on a clinical trial that included nearly 1,800 people. It was the most diverse trial for an Alzheimer's treatment to date, but still not enough to definitively say if the drug is effective for Black people. "[In] the world's most diverse Alzheimer's trial, a giant trial of 1,800 people that lasted for a much longer time than most trials did, we're still not sure that all of the groups that are at highest risk of Alzheimer's disease actually see any kind of benefit," says Dr. Jonathan Jackson, Assistant Professor of Neurology at Harvard Medical School.
