Short Wave - ‘Math In Drag’ Explores The Creativity And Beauty In Numbers

Kyne Santos was a student at the University of Waterloo when she began her math and her drag careers. She compares her double life to Hannah Montana, doing math equations at school by day and drag at night. You may already know Kyne from TikTok, where she makes educational videos about math, science, history and drag. And now, in her new book Math in Drag, Kyne explores the connections between math and drag: How both can be creative, beautiful and most of all, fun.

Science In Action - A humungous temporary tentacle

The ‘origami’ superpowers of a single-celled pond hunter, it hunts by launching a neck-like proboscis that can extend more than 30 times its body length. Manu Prakash of Stanford University reveals the amazing mathematical mechanisms of the protist, Lacrymaria olor.

It’s a microbe-eat-microbe world out there, with bacteria waging constant war against each other. It’s by dipping into their ever-evolving chemical arsenal that we keep our pharmacies supplied with the antibiotics we use to fight infectious bacteria - and computer biologist Luis Coelho of Queensland University of Technology has turned to genetics and AI to speed up the search for novel compounds.

Research from Elana Hobkirk at Durham University has found that the process of domestication and selective breeding has limited the ability of domestic dogs to use facial expressions to convey emotions as effectively as their wolf ancestors. Whilst we may be easily manipulated by the ‘puppy eyes’ of our pet dogs, they are no longer able to display the same range of emotions that wolves can, who need strong visual communication to maintain their packs.

Who discovered the first black hole? Science writer Marcus Chown tells us about the discovery of Cygnus X-1 discovered by Paul Murdin and Louise Webster in 1971.

And 100 years ago this week, Indian physicist Satyendra Nath Bose posted his revolutionary paper to Albert Einstein, which went on to influence quantum mechanics, low-temperature physics, atomic physics, and the physics of the particles that shape the Universe. Physicist Ajoy Ghatak and presenter Roland Pease discuss the story of the man who had the word ‘boson’ coined to memorialise him in the late 1920s.

Short Wave - Why The Science Of Tides Was Crucial For D-Day

June 6, 1944 the Allied Forces stormed the beaches of Normandy and took the Nazis by surprise in the largest sea-to-land invasion in history. This would be remembered as D-Day and would ultimately lead to the end of World War II in Europe. However, this planned attack wouldn't have been possible without deep knowledge of ocean tides! We get into the whole story, including why tides sit at the intersection of astronomy and marine ecology — and why understanding tides are key to a greener future.

Short Wave - Psychedelic Treatment For PTSD Faces Misconduct Hurdle

People with post-traumatic stress disorder (PTSD) may soon have a new treatment option: MDMA, the chemical found in ecstasy. In August, the Food and Drug Administration plans to decide whether MDMA-assisted therapy for PTSD will be approved for market based on years of research. But serious allegations of research misconduct may derail the approval timeline.

NPR science reporter Will Stone talks to host Emily Kwong about the clinical trials on MDMA-assisted therapy research and a recent report questioning the validity of the results.

CrowdScience - Why does wine taste better over time?

It’s often said that fine wine gets better with time, and this week’s oenophile listener Jeremy has a cellar full of dust-covered bottles. He is curious whether chemistry can account for the range of flavours that develop as wine matures, but also wonders why some of it tastes like vinegar if you leave it too long? We head off to the Bordeaux region of France, where vines were planted almost 2,000 years ago. Here, winemakers are joining forces with scientists to better understand wine ageing, a process so subtle and intricate that even the scientists refer to it as magic. In the world-famous vineyards of Chateau Margaux, presenter Marnie Chesterton learns that the key ingredient for good grapes is a sandy soil type; and that in this part of France, the warming climate is actually having a positive effect on the vines, which need very little water to thrive. Over in the lab, we meet the chemist mapping the molecules responsible for aromas associated with a well-aged Bordeaux. Featuring: Philippe Bascaules, Chateau Margaux Prof Cornelis van Leeuwen, Bordeaux Sciences Agro Dr Stephanie Marchand-Marion, ISVV Alexandre Pons, ISVV Presented by Marnie Chesterton Producer – Marijke Peters Editor – Cathy Edwards Production Co-ordinator – Liz Tuohy Studio Manager – Sarah Hockley

Unexpected Elements - Eternal flames

As the Olympic torch makes its way through France, we investigate the fires that continually smoulder and those which are stomped out.

You might expect snow to make a solid fire extinguisher, but in Canada, it is somehow keeping embers alight. These ‘Zombie fires’ keep burning through the winter, releasing huge amounts of carbon into the air and enhancing the tinderbox for summer wildfires.

While wildfires leave trails of destruction, for some plants and animals, they act as a catalyst for life – helping them to spread their seeds or flower. And the extent of these blazes can also be marshalled by nature – with elephants and beavers building natural fire breaks into landscapes to prevent uncontrollable flames.

We hear about when the first fires happened on Earth and how we can study ancient fires which have long since gone out. Plus, we unpick the key to monogamy (in mice), why cicadas love prime numbers as well as your thoughts on snakes...

Short Wave - A Silky Shark Named Genie Swam 17,000 Miles, a Record-Breaking Migration

A silky shark named Genie traveled from the Galapagos Islands out to the open ocean and back – over 17,000 miles – over the course of a year and a half. That's an average of 31 miles per day, making Genie's journey the longest recorded migration for a silky shark.

Marine scientist Pelayo Salinas de León and his team named Genie in honor of the late marine biologist Eugenie Clark – also known as "The Shark Lady." She devoted her life to the study of sharks and to improving their reputation.

Science In Action - Trusting AI with science

AI is already being used in every branch of science, and will become more and more a feature of future breakthroughs. But with its power to find subtle patterns in massive data sets comes a concern about how we will know when to trust its outcomes, and how to rely on its predictions. Science in Action talks to Alison Noble who just completed a Royal Society report on trust in scientific AI.

With highly pathogenic bird flu infecting around 70 dairy herds across 10 states in the USA, including a herd of alpacas, we get an update from health journalist Helen Branswell of StatNews on the latest science and efforts to get on top of the infection.

Also, from the pioneers of the mRNA vaccines that helped turn around the COVID pandemic, an experimental version that could be rolled out rapidly if the bird flu does cross worryingly into people. University of Pennsylvania’s Scott Hensley described how it works, and how promising it looks.

Science in Action also hears how Europe’s new EarthCARE satellite, equipped to peer deep inside clouds, will tackle one of the biggest unknowns in the science of global warming.

Short Wave - A Vaginal Microbiome Transplant Could Help People With BV

Humans rely on our symbiotic relationship with good microbes—in the gut, the skin and ... the vagina. Fatima Aysha Hussain studies what makes a healthy vaginal microbiome. She talks to host Emily Kwong about her long-term transplant study that asks the question: Can one vagina help another through a microbe donation?
