Encore episode. A deadly triangle of factors is killing off U.S. honeybees. Last year, forty percent of honeybee colonies died in the U.S., continuing an alarming trend. Entomologist Sammy Ramsey tells host Maddie Sofia about the "three P's" and what listeners can do to help our fuzzy-flighted friends.

Though Black Americans make up 13% of the U.S. population, they represent only 5% of physicians. How does that lack of diversity in the physician workforce impact Black patients' health and well-being? Dr. Owen Garrick, the CEO and President of Bridge Clinical Research, wanted to know.

Studies in children who have been severely affected by Covid-19 in Italy, Britain and the US are showing the same thing – a range of symptoms linked to an overactive immune system. Elizabeth Whittaker from London’s Imperial College discusses the similarities in these cases and possible reasons for this syndrome with Shanna Kowalsky from Mount Sinai hospital in New York.

How much should drugs for Covid-19 cost? Remdesivir, which has shown promise against the virus, has been priced at over $2000 for a course of treatment, but drug price analyst Andrew Hill says the cost of production is actually below $10.

And how about some really alternative energy? Marion Cromb at Glasgow University has run an experiment to simulate a spinning black hole. In theory, a rocket sent to an equivalent real black hole could use its rotation as a power source.

Shoes are a surprisingly recent human invention. But running isn’t. That means for most of our time on the planet, we’ve run barefoot. Today, in most countries, it’s rare to see people out in public without shoes, let alone running. But might our aversion to the free foot be causing us pain?

CrowdScience mega-fan Hnin is an experienced runner - she enjoys ultra-marathons back home in Australia. But about six months ago she developed extreme foot pain, the condition Plantar Fasciitis, and this meant she had to stop doing what she loves. She reached out to CrowdScience presenter Chhavi Sachdev, to find out if barefoot running could reduce her pain and improve her performance. Simply put, is barefoot running better?

In an attempt to find Hnin some answers, Chhavi hits the ground… running. Literally throwing off her own shoes on the streets of her home city of Mumbai, India, to see how feeling the ground can change her whole gait. And with Prof. Dan Lieberman, Chhavi learns what sets the human runner apart from other species, while uncovering the strange form our feet have. She speaks with Dr Peter Francis, a researcher whose life’s work has focused on curing the pain in his own feet and learning how to help others.

But performance is also important for runners. Biomechanics and shoe expert Dr Sharon Dixon explains how modifications to the sports-shoe are helping marathon runners set records, and blade-running athlete Kiran Kanojia shows Chhavi how the technology behind her two prosthetic legs let her emulate either natural walking or natural running.

A special episode from our colleagues at NPR's history podcast Throughline.

When a cook who carried typhoid fever showed no symptoms and refused to stop working, authorities forcibly quarantined her for nearly three decades. Was she a perfect villain? Or a woman scapegoated because of her background?

Throughline hosts Rund Abdelfatah and Ramtin Arablouei tell the story of Typhoid Mary — a story about journalism, the powers of the state, and the tension between personal freedom and public health.

“I grew up in this country,” says Gurminder K Bhambra, a professor at the University of Sussex’s School of Global Studies, “and [yet] I always thought I was an immigrant. School told me I was an immigrant; the media told me I was immigrant; everything around me was that I was immigrant. When the Brexit debates were happening, I was talking to my dad about this. He keeps things, so he pulled out his old passports, my grandparents’ old passports, and all the passports were British.”

“So I’ve always been a British citizen, my parents have always been British citizens, and my grandparents have always been British citizens – not because we lived in Britain, but we lived in those parts of the world that were the British Empire at the time. Britain came to us, incorporated us within its polity, within its understanding. We were seen to be British, and yet when we traveled within the imperial polity and ended up in Britain, somehow we became migrants.”

This account and its summary – “people constructed their Britishness in opposition to me, as opposed to inclusive of me” – encapsulates Bhambra’s academic field: postcolonial and decolonial studies. In this Social Science Bites podcast, she discusses with interviewer David Edmonds why we should speak about the Haitian revolution in the same breath as the contemporaneous American and French revolutions, how former empires conveniently forget the contributions of their colonies now that those empires have downgraded to mere ‘nations,’ and what lessons we should draw from the current iconoclastic impulse toward imperial statuary. (Bhambra says she’s less focused on statues themselves than in “the histories that are embodied within them, and the extent to which people know and understand those histories and what it means for us, in the public sphere, to be defined by them.”)

Their talk begins with a quick primer of the origin of the complementary fields of post-colonialism and decoloniality. Each examines the legacy and lasting effects of European colonialism, but use different times and places as their starting points.

Postcolonialism emerged after the publication of its “keystone text” - Edward Said’s Orientalism – in 1978. “I don’t think Said necessarily thought that he was setting out to create a field when he wrote this book,” Bhambra explains. “But it was so influential – initially within English literature but then the humanities more generally – that it built up a body of scholarship in its wake that came to be understood as post-colonial studies.”

Initially, postcolonialism was interested in the interplay between the Middle East and South Asia and of Europe, generally starting around the 19th century.

Decoloniality, in contrast, initially explored Europe and Latin America and the Caribbean beginning with Columbus encountering the Americas.

As these fields expanded throughout the humanities and into areas such as historical sociology, scholars sought “what the place of the colonial was within their disciplines, find it missing, and seek to explain that absence.”

One absence that Bhambra herself explored in her own studies and her book Rethinking Modernity: Postcolonialism and the Sociological Imagination is how ‘the modern’ came to be seen as the province of Europe (and its North American domains) and their three revolutions, the American, French and Industrial. Her research quickly showed here that while sociologists might disagree on some particulars, they fully agreed  that the modern world began with a dramatic break “between a pre-modern agrarian past and a modern industrial present, and that that temporal rupture could be located spatially within Europe, and that Europe (and North America is often encapsulated within this) marked a cultural separation from the rest of the world.”

That historical take is, she argues, a distortion. Modernity wasn’t manufactured in Manchester or drafted in a salon in Paris; it arose from existing colonial connections. “Modernity isn’t something that emerges endogenously and autonomously within Europe, from which it then spreads around the world. There were already global connections, and those connections were through processes of colonization, enslavement, imperialism, and so on. Those processes are the condition for things that we call modernity.”

The bill for that modernity, she adds, has yet to be paid in full.

“There is no institution in Britain or France to which colonial wealth has not contributed ... anybody who has an historical connection to the empire has a right to the wealth and benefits of what is now the nation.”

Meatpacking plants have been some of the biggest COVID-19 hot spots in the country. Thousands of workers have been infected, dozens have died. As plants reopen, one strategy has helped slow the virus's spread: large-scale employee testing. NPR food and agriculture correspondent Dan Charles explains how this approach could be a lesson for other industries as well.

NASA is on a mission to explore Titan — the largest moon of Saturn. To do that, scientists are building a nuclear-powered, self-driving drone (technically an octocopter) called Dragonfly. Scheduled to launch in 2026 and arrive on Titan in 2034, Dragonfly could provide clues about how the building blocks of life started here on Earth.
