The COVID-19 public health emergency has ended, but millions across the globe continue to deal with Long COVID. Researchers are still pursuing basic questions about Long COVID — its causes, how to test for it and how it progresses. Today, we look at a group of researchers studying the blood of some Long COVID patients in the hopes of finding a biomarker that could let physicians test for the disease.

Lazy. Unmotivated. Procrastinating. If those are words you’re used to hearing from your inner critic, you are not alone. Take CrowdScience listener Laurie. On her days off she loves to relax on the sofa, watch TV, put off chores and generally do as little as possible. Meanwhile she sees other family members and colleagues apparently buzzing with energy: going the extra mile at work, taking up hobbies, going to the gym. Why, she asks, is she so lazy?

CrowdScience turns to experts to find out whether or not so-called ‘laziness’ is a fundamental part of biology or psychology; why some people have more energy than others; and we offer a few tips for boosting energy and motivation. Or maybe Laurie is just being a bit too hard on herself?

With psychologists Professor Fuschia Sirois and Dr Devon Price, anthropologist Professor Herman Pontzer and start-up entrepreneur Akhil Aryan.

There's a lot for scientists to learn about the origins of humans' musical abilities. In the last few years, though, they've discovered homo sapiens have some company in our ability to make musical rhythm. That's why today, producer Berly McCoy brings the story of singing lemurs. She explains how their harmonies could help answer questions about the beginnings of humans' musical abilities, and what all of this has to do with Queen.

In 2003, an incredible scientific milestone was achieved as the first human genome completed sequencing. For 20 years, this genome has been used as a reference by researchers for comparison to all other DNA sequences. Now, the Human Pangenome Reference Consortium is addressing the lack of genetic diversity starting with 47 new reference genomes. Members of the consortium, Dr Karen Miga, assistant professor, UC Santa Cruz Genomics Institute and Dr Benedict Paten, associate professor, UC Santa Cruz Genomics Institute, join Roland to discuss the first stages of the project. For the first time the public will have access to thousands of documents from the Royal Society’s historical collections following their digitisation. Science correspondent Vic Gill visits the vaults to see some of these pieces of history first hand. We are also taking a trip 30km above the Earth, to the stratosphere, where Daniel Bowman, principal scientist from Sandia National Laboratories, is using solar powered balloons to listen to the mysterious sounds of our planet.

Unexpected Elements is all about finding surprising stories and nuggets of science in everyday news. Each week we start by taking a news story that’s floating around and use that as a launchpad for three other science stories that become increasingly unexpected.

This week, the team squints at the recent lavish ceremony and ritual of the British King’s coronation and asks: What does it all mean? Why is ritual so important to us humans, and why does it always seem to involve precious objects?

That’s where we start - but in this show, our global panel of science journalists can take us to all sorts of places. We’ll be touring the ocean floors with the scientist who wants to map all of them, soaring in the skies of India to discover why one of the country’s biggest birds might be in trouble, and we’re even going off planet to find out about an asteroid with enough gold in it to build a nice shiny house out of the stuff – for every human on Earth.

This week, the American Psychological Association issued its first-of-kind guidelines for parents to increase protection for children online. It comes at a time of rising rates of depression and anxiety among teens.

This episode, NPR science correspondent Michaeleen Doucleff looks into the data on how that seismic change has shifted the mental health of teenagers. In her reporting, she found that the seismic shift of smartphones and social media has re-defined how teens socialize, communicate and even sleep.

Today on the show, we meet a prosthetic designer and a neuroscientist fascinated with understanding how the brain and body might adapt to something we haven't had before — a third thumb. Dani Clode and Tamar Makin spoke to Short Wave in Washington D.C., at the 2023 annual meeting for the American Association for the Advancement of Science (AAAS).

Meet the ostrich, one of nature’s most unusual creatures: a two-metre-tall, flightless bird that struts about the African savannah. CrowdScience listener Pat found herself entranced by seeing them on a wildlife documentary, where two ostriches were exhibiting some bizarre behaviour. According to her, the female was sitting on her eggs in a ‘nest’ that was barely a dent in the ground, while the male was just flapping his feathers around her. So Pat came to us to ask: what are ostriches for? Anand Jagatia starts by meeting one face-to-face at Woburn Safari Park. Tom Robson, Head of Reserves at the park, gives Anand a tour of ostriches’ unique features. He discusses their status as the largest and fastest birds in the world and explains the unusual mating behaviour Pat observed on the TV programme she was watching. Next, to answer why some of these traits exist, Peter Houde from New Mexico State University dives into the ancient fossils. Peter is one of the palaeontologists who has managed to uncover the secrets of ostrich origins. What did their ancestors look like -- and why did they lose the ability to fly? Ostriches are also a part of human culture. Their eggs, for example, have been objects of value for thousands of years. Archaeologist Tamar Hodos from the University of Bristol explains how decorated ostrich eggs have been uncovered from ancient tombs and how they were probably used as pouring vessels as well as status symbols.

Anand receives an ostrich egg in the post and manages to cook it using a very specific and British process. Finally, designer Pascale Theron tells us about the history of the ostrich farming industry. It’s a classic rags-to-riches-to-rags tale, a manic boom at the start of the 20th Century all based around feathers that were worth their weight in gold.

Another week comes by, and luckily so does our roundup of science news. This time, we've got some questions about better understanding our health: Why do some people get motion sickness from virtual reality (VR) content? Do we really need to walk 10,000 steps a day? And is there real science behind ice baths?

This week, Sacha Pfeiffer, legendary reporter and occasional host of NPR's All Things Considered, who joins our hosts Emily Kwong and Regina G. Barber to demystify and (in some cases) debunk the science of this week's health headlines.

We love hearing what you're reading and what science catches your eye! Reach the show by emailing shortwave@npr.org.

India is at the centre of much of the discussion on this week’s episode of Science In Action.

We hear about how a proposal to scrap Darwinian evolution from Indian secondary schools has led to signatures from thousands of scientists. Dr Vineeta Bal, Researcher at the National University of Immunology, is one of the signatories on a petition against the proposed changes. We spoke to her about why she is against them.

Also in India, a new Sars-Cov-2 variant, named XBBX.16 is being studied by epidemiologists in the country. Dr Rajesh Karyakarte, professor of microbiology at BJ Government Medical College, Pune, India, is behind the study.

Further study of the variant has been looked into by Kei Sato, professor of Systems Virology at the University of Tokyo. Kei has been mapping how new variants could cause us problems, ahead of them doing so.

This kind of forward planning is something praised by Paul Bienaisz, Professor of Virology at The Rockefeller university. We talk to him about how vital this kind of work still is, even if many of us have confined the about the SARS-CoV-2 pandemic to memory.

Lastly, we hear from Dr Usama Kadri, Senior Lecturer in Applied Mathematics at Cardiff University who has looked at how we might be able to use a novel bit of technology of underwater technology (called hydrophones), often used for animal conservation, to be able to detect earthquakes in the deep sea.
