Episode's summary
If you've ever seen an infant lying on its back, you've surely seen them endlessly waving their arms and legs in seemingly haphazard ways. And crying? To the uneducated eye and ear, it does all seem a little... unplanned. But from their earliest moments, infants actually cry in a way that suggests they're already learning the patterns of their mother's language while in the womb! And when you see them waving their arms around? They're actually deliberately trying to figure out what this thing is on the end of their arm, and how can they get it to do what they want? The way babies move not only tells us loads about healthy infant development, but about whether things might not be quite right, especially when it comes to problems such as cerebral palsy. Today's guests help us decode the meanings of these movements, why they matter, and what parents in particular need to know to help stimulate their babies' development in the best possible way. Our first guest, Audrey van der Meer, a professor of…

What babies can tell us – and why we need to listen
ListenedIf you've ever seen an infant lying on its back, you've surely seen them endlessly waving their arms and legs in seemingly haphazard ways. And crying?

ENCORE: When the doctor is out
ListenedENCORE: This episode was first published in Oct. 2023. Sierra Leone used to be the most dangerous place in the world to give birth. Without enough doctors to do C-sections, women and babies were dying. But what if you didn't need a doctor? This week, the story of two determined surgeons and a no-so radical idea that is saving lives in Sierra Leone — one emergency operation at a time. You can read more about the non-profit organization the doctors created at capacare.org Our guests on the show are Håkon Bolkan, Alex van Duinen and Emmanuel Tommy.

ENCORE: Running rats and healing hearts
ListenedENCORE: This episode was first published in Sept. 2023. In 1998, a young Norwegian exercise physiologist found that a technique he had used to help Olympic athletes could help heart patients too. But his idea made doctors sweat. One famous cardiologist told him that if he used his technique in human heart attack patients, he "would kill them." Today's show looks at what happened when our researcher, Ulrik Wisløff, defied the experts — and built a career learning how high intensity interval training can help everyone from heart patients and ageing Baby Boomers, and possibly even Alzheimer's patients — but not in the way you might think! Today's guests are Ulrik Wisløff, Dorthe Stensvold and Atefe Tari. Here's a link to a rat on a treadmill photo. And here's a link to a transcript. Here's a list of some of the research mentioned in the podcast: Wisløff U, et al. Intensity-controlled treadmill running in rats: VO(2 max) and cardiac hypertrophy. Am J Physiol Heart Circ Physiol. 2001 Mar;280(3):H1301-10. Wisløff…
Walrus tusks were Viking age gold
ListenedHistorians have floated a half-dozen theories for why Viking Greenland settlements suddenly vanished in the 1300s and 1400s, after nearly 500 years of occupation. Was it climate change, the Black Death, even bad farming habits learned in Scandinavia? But what if…it all came down to walrus ivory? It turns out that walrus tusks during the Viking and Middle Ages fuelled a long-distance trade network that stretched from Inuit hunters far above the Arctic Circle to churches and royalty in cities as far flung as Novgorod, Kyiv and Cologne. Now, using ancient DNA and isotope analysis, archaeologists have shown that virtually all these tusks came from Greenland! And then suddenly, the market collapsed. What happened? Today's show looks at how everything from cutting edge technology to dogged footwork has allowed researchers to piece together the details of the global walrus trade a thousand years back in time. They're also using this window into the past to better understand walruses themselves, to make predictions…
An accidental discovery: From failed experiment to new antibiotic
ListenedNTNU professor Marit Otterlei nearly threw out the contaminated cell culture where she and her colleagues were testing a new cancer drug. The problem arose on a hot summer day, in Trondheim, in a country not known for hot summer days. So they'd opened the lab's windows overnight. When they came back the next day, they found an uninvited guest, snuggled in with their cancer cell culture: Bacteria!!! Here's the thing, though: although the drug had been designed to work on human cancer cells, it looked like it had killed the bacteria, too! That was remarkable, because the cancer drug targeted a specific mechanism that human cells use to replicate. It looked like the drug also targeted the same mechanism in bacteria -- even though the tree of life had branched away from bacteria 3 BILLION years ago! How could that be? Today's podcast takes a peek into the challenging world of what it takes to bring a drug, especially an antibiotic, to market. But it’s also an inside look into how some researchers, with their…
