This researcher wants a new particle accelerator to use before she's dead

Quirks and Quarks9:05This researcher wants a new particle accelerator to use before she’s dead

Physicists exploring the nature of reality need ever more capable particle colliders, so they're exploring a successor to the Large Hadron Collider in Europe. But that new machine is at least decades away. Tova Holmes, an assistant professor at the University of Tennessee, Knoxville, is one of the physicists calling for a different kind of collider that can come online before the end of her career – or her life. This device would use a particle not typically used in particle accelerators: the muon.

The proposed new particle accelerator would require an even larger tunnel, one that’s over 100 kilometres. Physicists calling for the development of a muon accelerator say it will require much less space. (Samuel Joseph Hertzog/CERN)

Is venting the best way to deal with anger? The scientist says chill out.

Quirks and Quarks6:51Is venting the best way to deal with anger? The scientist says chill out

It turns out that acting out your anger might not be the best way to get rid of it. Sophie Kjaervik, a researcher at Virginia Commonwealth University in Richmond, Va., analyzed 154 studies of the different ways to deal with anger. Her results, published in the journal Clinical Psychology Review, suggest that techniques that reduce your heart rate and calm your mind are more effective than blowing off steam.

High intensity wildfires may release toxic forms of metals

Quirks and Quarks8:37High intensity wildfires may release toxic forms of metals

Wildfire smoke might be more dangerous than you think. A recent study in the journal Nature Communications found that when wildfires pass over soils or rocks rich in a normally harmless metal called chromium, it is transformed into a toxic form. The hotter and more intense the wildfire is, the more of this metal becomes toxic. Scott Fendorf, an Earth system science professor at Stanford University, said this study shows we should factor in the type of geology wildfires pass over to provide more targeted air quality warnings about smoke risks.

AI might help solve the problem of runaway conspiracy theories

Quirks and Quarks7:35AI might help solve the problem of runaway conspiracy theories

Conspiracy theories seem to have multiplied in the internet era and so far, we haven't had much luck in debunking these beliefs. The preliminary findings of a new study on PsyArXiv, a site for psychology studies that have yet to be peer-reviewed, suggests that artificial intelligence may have more success. Thomas Costello, a postdoctoral psychology researcher at MIT was the lead author on this study, and said their findings can provide a window into how to better debunk conspiracy beliefs.

An Indigenous scientist explores the medicine the Earth needs

Quirks and Quarks19:12An Indigenous ecologist on why we need to stop and listen to save the planet

Earth day is April 22. And Earth is not in great shape to celebrate the day. Overheated, overpopulated, overexploited – we're not being particularly careful with our planet. We talk to Indigenous ecologist Jennifer Grenz of the University of British Columbia about her new book, which is part memoir, part prescription for the medicine our planet needs – a compound of science and traditional wisdom.  Her book is Medicine Wheel for the Planet: A journey toward personal and ecological healing.
