How dandelion seeds take flight, and more…

In a study inspired by a field of dandelions, researchers wanted to know why, when you blow on a dandelion seed head, only the seeds closest to you take flight. They found that a dimple in the seed heads where the seed attaches is larger on one side than the other, and that the seeds consistently broke off from the smaller side of that dimple. Once they take flight, each dandelion seed uses its unique shape to catch a ride on the wind.PLUS:Infrasound, not ghosts, may be why old buildings give us the

On the morning of August 10, 2025, a landslide in a fjord along the southern Alaskan coast triggered a mega tsunami. It generated the second highest wave ever recorded that reached up to 481 metres above sea level. A new study suggests that catastrophic events like this are more likely to occur as our climate warms and glaciers melt.PLUS:The hantavirus at the centre of the outbreak struck Argentina in 2018.

2026/05/01

Cocaine and many other chemicals and drugs are found in many waterways, but especially around wastewater treatment plants. Scientists exposed wild juvenile Atlantic salmon to cocaine and its byproduct to see how it impacted their behaviour in the wild. As a result, the fish swam twice as far, which could put them in more danger.

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
