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.

A doctor's job is to help patients. With that help, often comes lots and lots of paperwork. That's where some startups are betting artificial intelligence may come in. The hope is that chatbots could generate data like treatment plans that would let doctors spend less time on paperwork and more time with their patients. But some academics warn biases and errors could hurt patients.

In the 1970s and early 1980s, when Shinobu Kitayama was studying psychology at Kyoto University, Cognitive Dissonance Theory and Attribution Theory were “really hot topics” that he found “intellectually interesting” ways of describing human behavior.
“But when I came here [to the University of Michigan] and looked at my graduate students, colleagues, and friends, I realized that those ideas are really active elements of their mind in a way they were not to me as Japanese individual.”
He continues, “obviously there are many cultural shocks – for example, I felt hesitant in speaking up in graduate seminar, but I got the impression that American friends end up saying a lot of things seemingly without thinking anything. That’s the kind of experience that made me feel that something more profound might be going on in terms of culture and its influence on psychological processes.”
His own perch, he explains in this Social Science Bites podcast, helped focus his personal research into comparing people from East Asia, such as Japan, China, and the Philippines, with people in America. His research ranges from simple exercises involving redrawing a line within a box to brain-scanning technology (“culture gets under the skin,” he jokes before adding, “I find neuroscience indispensable”) and examinations of subsistence agriculture. The Robert B. Zajonc Collegiate Professor of Psychology at Michigan since 2011 now runs the Culture & Cognition Lab at the school’s Psychology Department.
He starts his conversation with interviewer David Edmonds offering a description of a prominent cultural difference between East Asia and Anglo-America - the idea of ‘independence’ and ‘interdependence.’
“In some cultures, particularly in Western traditions, ‘self’ is believed to be the independent entity that is composed of internal attributes, maybe your attitudes, maybe your personality traits and aspirations, which guide your behavior. Social relationships come out of those individual preferences.
“In many other cultures, the conception of the person is much more social and relational. There’s a fundamental belief that humans are humans because they are connected to formal social relationships.”
Kitayama offers some examples of these differences. “Americans tend to believe that what you hear somebody say must be what this person believes. If somebody says ‘yes,’ he must mean yes. But in many countries, ‘yes’ and ‘no’ carry very different meanings, depending on the context.” While someone from, say, the West may realize this on an intellectual level, in practice they often forget and assume a yes, means, well, yes. “We found this fundamental attribution error,” he concludes, “is much less, and often even nonexistent, in East Asian, and particularly Japanese, contexts.”
Or take happiness.
“Oftentimes, we believe that happiness is happiness. If Americans are happy, it must be in the way that Japanese are happy. We try to challenge this conception to see what people might mean when they claim they are happy. One easy way to do this is to ask people to write down what they mean by happiness, reasons for happiness, conditions in which happiness happens. Core elements of happiness, like elation, relaxation, feeling of excitement, are fairly common between U.S. and Japan.”
But what leads to those states are quite different, with Japanese respondents often citing social harmony while Americans cite personal achievement.
In the interview, Kitayama touches on why these differences might have arisen, including one idea that the cultivation of mainstay grains across thousands of years helped create the conditions that led to the cultural traits. The Asian staple of rice, for example, requires a more collective effort – “tight social coordination,” as Kitayama puts it -- to raise and harvest. Meanwhile, the Western staple of wheat requires less collaboration. These underlying agrarian requirements for supremely important foodstuffs may in turn, he says, “promote very different ideologies and social structures and institutions which then lay the ground for contemporary culture.”
Kitayama has published widely in English and in Japanese and served as editor of the Journal of Personality and Social Psychology: Attitudes and Social Cognition and the Personality and Social Psychology Bulletin. He was a fellow of the Center for Advanced Studies of Behavioral Science at Stanford in 1995 and in 2007, a Guggenheim Fellow in 2010, inducted as a fellow of the American Association for the Advancement of Science in 2012, and served as president of the Association for Psychological Science in 2020.
Today on the show, next-generation energy innovators Bill David and Serena Cussen challenged us to think about the future of clean energy storage. They spoke to Emily Kwong at the 2023 annual meeting for the American Association for the Advancement of Science (AAAS) in Washington D.C.
Inside our gut lives an entire ecosystem of bacteria and microbes, called the microbiome. In fact, the human body contains trillions of microorganisms, which outnumber our cells by ten to one. This means that technically we are more microbe than human. But not only do these microbes rely on us to survive, we also rely on them for some vital bodily functions. So what impact do these trillions of microbes have on our health? That’s the question that’s been bothering CrowdScience listener Russell, from Canada.
Presenter Caroline Steel investigates. She visits the only museum in the world dedicated to microbes to ask exactly what they are, what they do and why we have so many of them inside our bodies. And she visits a microbiology lab filled with model guts to find out what impact the microbiome has on our physical health and if there is anything we can do to help our microbes function better.
Caroline finds out what impacts our microbiome, what we can do to improve our inner ecosystem, and how our microbes can take a disturbing turn on us after we die.
