Quirks and Quarks

IDEAS, hosted by Nahlah Ayed is a weekday podcast that explores how ideas shape our world.“One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists in the ‘70s. Nevertheless, Rossiter persisted. She found and documented hundreds of women whose contributions to science had been overlooked, under-credited and misappropriated. Then she made history herself by coining the term “The Matilda Effect” to describe why those women failed to get the credit they deserved. Who is Matilda? Matilda Joslyn Gage was a suffragist erased from history. She was known as being too radical for Susan B. Anthony. This episode of IDEAS shares her story.You can find more episodes of IDEAS wherever you get your podcasts, and here: https://link.mgln.ai/IDEASxQQ

There's been a growing movement to develop new technologies to replace at least some of the animals used in scientific research. Researchers across Canada are working to create these tools, to usher in a new animal-free era for medical science.PLUS:Harbor seals can 'talk' thanks to their parrot-like brains'Flaming hot' water ice may explain Neptune and Uranus' strange magnetismA thigh bone that could represent the oldest evidence of our human lineageThe ravens of Yellowstone remember where wolves typically kill their prey

On their mission around the moon, Jeremy Hansen and his crewmates will become the only four people on Earth to ever lay eyes on the entire far side of the moon.
