Being more social has a ton of benefits: lower stress, decreased inflammation – even living a longer life! Recently, some scientists have added lowering your blood sugar to the list. To figure it out, researchers had people break bread both in duos and alone. And they think the results could tell us something about the roots of our social nature. Consider it another reason to prioritize our social lives.  Interested in more science in the news? Email us your question at [email protected].

If you, like us, clicked on the cute cat photos posted everywhere recently, announcing the discovery of the first new cat species in more than a century, you might have wondered how rare it is to find a new species. Turns out, it’s not! We live in an era of “unprecedented” discovery, says John Wiens, a professor of ecology and evolutionary biology at the University of Arizona. And scientists say we’re still just scratching at the surface of how much life exists on Earth.    Interested in more science in the news? Email us your question at [email protected].

Inflammation is all over our feeds. Influencers claim it’s the reason you're bloated or fatigued, the source of digestive problems and the cause of more serious illnesses like Alzheimer's or cardiovascular disease. But how much of that is scientifically backed, and how viable are the solutions you see on social media? Short Wave talks to immunologist Shruti Naik to separate the health from the hype.  Interested in more wellness science? Email us your question at [email protected].

Leaves turn yellow in the fall because Chlorophyll breaks down, revealing the yellow pigment that was there all along. But why red? Red is a different story altogether. Leaves have to make a new pigment to turn red. Why would a dying leaf go an extra mile to do that? Scientists don’t really know. NPR science correspondent Nell Greenfieldboyce reports on the leading hypotheses out there. Read more of Nell's reporting on this topic.  Interested in more seasonal science?

The world is bracing for the worst effects of a Super El Niño. Or a Godzilla El Niño. But what does that really even mean? For millennia El Niño has shaped weather across the globe, fueling flooding in parts of the U.S., droughts and wildfires in Australia and Indonesia, and disrupting fisheries across the Pacific. Scientists have long wondered if human activities — chiefly the burning of fossil fuels — are making El Niños stronger. Now, on the eve of the strongest El Niño on record, a team of researchers think they have an answer. Interested in more science behind the weather? Email us your question at [email protected].

Measles is making a comeback. Ongoing outbreaks in Pennsylvania, South Carolina, Texas, and Utah have documented hundreds of cases, mostly among unvaccinated people. And while local and federal politicians debate the definitions and impact of those measles-associated deaths, health experts worry that we’re overlooking the real problem: the threat of a full-scale epidemic. Today, we talk to one of those experts – epidemiologist Michael Mina – to figure out who’s most at risk and whether there’s any way for us to turn this epidemic around.

Your self-worth today can be affected by your memories. But you have power over those memories – when you re-experience them. By doing that, you can reshape your self-esteem for the better and change your perspective. That idea and the broader science of self-worth are at the heart of Marisa Franco’s new book Worth. It’s so intriguing to us, we couldn’t pass up the chance to share it with you. That’s why today’s episode is a peek at a conversation Marisa had about self-worth on NPR’s self-help podcast Life Kit.

Remember your mom, dad and teachers telling you to read because it’s good for you? Well, a compilation of the latest research shows they were right. “Reading is one of the simplest and most accessible activities for actually supporting cognitive performance, brain health, mental health, but also overall wellbeing throughout our lives,” said Christelle Langley, a cognitive neuroscientist at the University of Cambridge and co-author of review, published in the journal Psychological Medicine. The review looked specifically at recreational reading — reading for fun — and found broad benefits for children, adolescents and older adults. This episode, we dive deep into the joys and health benefits of bookmaxxing.  Interested in the science of reading? Email us your question at [email protected].

AI is in the news again – for its potential to end civilization. A researcher at Anthropic resigned very publicly last week, citing concerns about the accelerating capabilities of AI and what he called “irresponsible” behavior from major AI companies Anthropic and OpenAI. Following his resignation, the leaders of both companies called for an internationally cooperative, industry-wide slowdown on advanced AI development. And Wednesday, OpenAI disclosed six more incidents of “unexpected or concerning model behavior” and debuted a new framework for reporting misalignments. So, given all these events, how worried should we be about the future of AI? And what safety measures are – or could be – set in place to safeguard humanity? NPR’s power and policy reporter Huo Jingnan reports. Interested in more science and technology news? Email us your question at [email protected].

For years, renewable energy companies have faced a problem: How to store the mass amounts of energy they produce for later use. Batteries may be just the solution. In California, there's now enough grid-scale battery storage to power millions of homes for a few hours. Battery power is often the second largest source of energy on a given day in the state. So, we're revisiting the fast-growing technology with Cooper Katz McKim, a producer on The Indicator from Planet Money. Listen to the three-part battery series.

Nearly every person will experience at least one diagnostic error in their lifetime. That means either a delayed diagnosis, a wrong diagnosis – or no diagnosis at all. That’s according to a report by the National Academies of Sciences, Engineering and Medicine from 2015 on diagnostic error. Today on the show we talk to a physician who was personally affected by the crisis, and New York Times editor and author of the book The Elusive Body: Patients, Doctors and the Diagnosis Crisis.

BMI is a quick, cheap way for doctors to estimate body fat and screen for conditions like heart disease and diabetes. But medicine has long known that BMI is problematic and unnuanced. By using it, groups of people have fallen through the cracks and conditions have been caught late. So, some doctors want to add nuance – to consider race when using BMI. But using race in medicine comes with its own problems. So what’s the way forward? To find out, we talk to Katie Wu, a science writer at The Atlantic. Read more of Katie’s reporting on BMI and race.

When people are sick, we seek out medications and treatments to help heal. For a long time, scientists thought that was a uniquely human ability. But it turns out, many other animals do a version of it too! And since the late 1980s, western researchers have been trying to get a peek behind the curtain. And aside from just cataloguing all the cool examples just to know, there’s a real hope that studying animals’ medical cabinets may be the most promising way to expand our own. We get into the weeds with freelance science journalist Mandy Nguyen. Interested in more animal stories? Email us your ideas and questions to explore at [email protected].

Hurricane season is upon us and it turns out that these powerful storms can quickly affect the biology of animals. After hurricanes Irma and Maria hit the islands that make up Turks and Caicos about a decade ago, the silver key anole adapted. They now have a shorter fourth toe on their hind legs! That could help them cling to objects better. But how do you know unless you put lizards in front of a fan and record how long they can hold on? This study is out now in the journal Current Biology.
