For Black History Month, Short Wave is celebrating Black voices in STEM - bringing back some of our favorite conversations, as well as new guests with expertise and insights to share. In this encore episode, former Short Wave host Maddie Sofia talks to inventor James West about his life, career, and about how a device he helped invent in the 60's made their interview possible.

At Short Wave, it's an unspoken goal to ask and answer every question under the sun — after all, science underpins the entire universe. Today, we think we've finally met our curiosity match in mathematician Hannah Fry and geneticist Adam Rutherford. They're the duo behind the science mystery podcast The Curious Cases of Rutherford and Fry and co-authors of the new book Rutherford & Fry's Complete Guide to Absolutely Everything (Abridged). In the book, they ask questions like: How old is the Earth? Does your dog love you? And, is there free will?

Obviously, the middle question is of particular interest.

Are you also curious about a scientific mystery? DM us the old-fashioned way — over email at shortwave@npr.org. We'll open an investigation.

Triple axel, double lutz, toe loops, salchows — it's time to fall in love again with the sport of figure skating. The 2022 Winter Olympics in Beijing are underway, and today on the show, Emily Kwong talks with biomechanic Deborah King about some of the physics behind figure skating. Plus, we go to an ice rink to see it all in action.

We’re 40 years into the AIDS pandemic, and even with massive public health campaigns, still, 1 ½ million become infected with HIV each year; about half that number die of its ravages. And a study just out shows that this well-understood virus can still take on more worrying forms as a new variant has been uncovered. Although the total number of cases involved is small, and the new variant is as treatable as earlier strains, the finding underlines that viruses can become more infectious and more virulent.

Back in October 2020, before we had effective vaccines, 36 plucky volunteers agreed to be deliberately infected with SARS-CoV-2 in order to better understand the infection process and outcomes in what’s known as a human “challenge” trial. Dr. Chris Chiu from Imperial College reveals what they’ve learned now the results of the study are in. We’ll hear about a new plastic that’s stronger than steel and as many gardeners have long suspected, – spring-flowering has over many years been occurring earlier and earlier, at least according to a new UK study. We discuss the implications for the ecosystem.

Imagine spending six months of every year living in total shade. That’s what life is like for residents of the Norwegian town of Rjukan, set so low in a valley that they see no direct sunshine at all from October to March. Marnie Chesterton heads there to hear about an ingenious solution: giant mirrors that beam rays down into the town square, where locals gather to feel the reflected heat. The man behind the project was motivated by a need for winter sun – but how much difference does it really make to our health and happiness? That’s the question posed by this week’s Crowdscience listener Michael, who has noticed living in the rainy Australian city of Melbourne is taking its toll. Many pensioners claim sunshine relieves achiness as well as conditions like arthritis but one of the biggest scientific studies found temperature actually has no impact on reported pain levels, while factors like air pressure and humidity may play a role. When it comes to our mood, it seems that spending time outside is more important than feeling the heat and the optimum temperature for wellbeing is around cool 19 degrees centigrade, while excessive warm weather has been linked to an increase in violence and crime.

In 2015, the National Institutes of Health ended invasive biomedical research on its hundreds of chimps. Since then, it's been gradually moving the animals to a sanctuary in Louisiana called Chimp Haven. NPR science correspondent Nell Greenfieldboyce joins the show to talk about the NIH's effort to retire research chimps and why it's complicated.

The Fourth Circuit Court of Appeals is deciding whether a Baltimore case against more than a dozen oil and gas companies will be heard in state or federal court. The city argues the companies are liable for the local costs of climate change. It wants the case heard in state court, which is governed by robust consumer protection laws. But industry lawyers are fighting hard to have it and more than 20 other similar lawsuits nationwide tried in federal court, where the oil and gas industry may be more likely to prevail.

NPR climate correspondent Rebecca Hersher, brings an update on the case, which went before the U.S. Supreme court last year. She explains how this pending decision may prove key to determining who pays for climate change.
