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.

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.

Cylita Guy was a curious child who enjoyed exploring the beaches, parks and animals that shared her hometown of Toronto, Canada. She's a scientist – an urban ecologist – interested in city-dwelling bats. Cylita talks to guest host Lauren Sommer about the importance of studying wildlife in cities, and about her children's book, Chasing Bats and Tracking Rats: Urban Ecology, Community Science and How We Share Our Cities.

This episode was produced by Berly McCoy, edited by Stephanie O'Neill and fact checked by Katherine Sypher. The audio engineer for this episode was Patrick Murray.

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.

The idea of walking a mile in someone else’s shoes is often trotted out as a metaphor for understanding empathy. The act of imagining someone else’s reactions may be hard, but based on the body of work by George Loewenstein, predicting how -- under varying circumstances -- we might walk in our own shoes may not be all that easier.

Loewenstein is the Herbert A. Simon University Professor of Economics and Psychology at Carnegie Mellon University in Pittsburgh, Pennsylvania. His enormous range of research interests can be boiled down, after a lot of boiling, to applying psychology to economics and, more recently, economics to psychology.

His career as a founder of both behavioral economics and neuro-economics has seen him delve deeply into how we react when our “affective state” is cold – when are emotions are absent and our physical needs are currently met – compared to when our affective state is hot. The latter is when out emotions are active or when our passions, as the old philosophers might term things like things hunger, thirst, pain, sexual desire, are pulling us.

It turns out, as he explains to interview David Edmonds in this Social Science Bites podcast, “when we are in one affective state it’s difficult for us to imagine how we would behave if we were in a different affective state. … The worst mistakes we make are when we are in a cold state, because we just can’t imagine how we would behave if we were in a hot state.”

While this may seem like something we know intuitively (or after years of high-profile experiments by Lowenstein, his frequent collaborator Leaf VanBoven, and others have conducted, several described in this podcast), it’s not something we act on intuitively. “No matter how many times we experience fluctuations in affective states,” Loewenstein says, “it just seems we don’t learn about this. We are always going to mis-predict how we’re going to behave when we’re in a hot state if we’re making the prediction when we’re in a cold state.”

This, in turn, affects the products of people who make predictions (or if you prefer, policy prescriptions) as a profession, he adds, such as economists.

“According to conventional economics, when we make decisions about the future we should be thing about what it is will we want in the future. What all of these results show is that your current state influences your prediction about what you’re going to want in the future; it influences these decisions that we make for the future in unproductive, self-destructive ways.”

As COVID-19 cases in the U.S. drop, the hospitalization rate remains high — as does the death rate. Experts say getting a COVID vaccine booster is key to maintaining immunity, but only about half of all vaccinated people in the U.S. have gotten the booster, which increases protection against both serious illness and death from the Omicron variant. Still, many infectious disease experts are cautiously optimistic for the coming months, pointing to it as a time to bolster our defenses against the virus.

Today we're bringing you an episode from our friends at NPR's Pop Culture Happy Hour.

They review the new HBO Max miniseries Station Eleven, based on the 2014 novel by author Emily St. John Mandel. The show's premise might sound eerily familiar: it begins with a highly contagious and deadly virus wiping out most of the world's population. The show then follows survivors through the pandemic's aftermath, as they decide how to rebuild what they've lost.

There are now a number of biological indicators for the potential development of long covid. Immunologist Onur Boyman of Zurich University Hospital and Claire Steves, Clinical Senior Lecturer at King’s College London strives to tell us how pinpointing these factors is now helping in the development of strategies to predict the syndrome and prepare treatment.

The James Webb telescope has reached its final orbit. The years of planning, preparation and rehearsal seem to have paid off. The telescope is now ready to begin its mission of looking back into the early universe. BBC Science correspondent Jonathan Amos has followed the mission.

The widely held view that human development was propelled by our ancestors developing a taste for meat is being questioned by a new analysis of the fossil record. Paleoanthropologist Andrew Barr of George Washington University suggests part of the reason for this assumption is the sampling method, actively looking for evidence to support the hypothesis.

And Michael Boudoin of Lille University has led a team of physicists who have produced the longest-lasting soap bubble ever – they managed to prevent the bubble from popping for well over a year.

Also, How is a small budget pocket radio able to recreate all the atmosphere and sounds of a football match? CrowdScience listener Andy wants to know about the science enabling his radio listening, so presenter CrowdScience Geoff Marsh sets off - microphone in hand - to follow the journey of sound on the radio.

Starting with the microphone, Geoff learns how acoustic energy is converted into electrical signals. Then BBC World Service presenter Gareth takes Geoff to a little-known room in the BBC called the Radio Shack. Gareth demonstrates how these electrical signals are attached to radio waves before being sent over the airwaves and they take a radio kit apart to understand how these waves are received and converted back into sound waves. Geoff talks to a speech and hearing specialist who, through the use of auditory illusions, shows Geoff that our brains are often filling in the gaps of lower quality audio.

Finally, Geoff visits an acoustic lab at Salford University where he hears a demonstration of ‘object based audio’. This technology could enable us to create our own bespoke mix of dramas and sports, such as heightening the commentary sound or choosing to hear just the crowd, just by using the everyday speakers many have lying around them, such as mobile phones.
