What if the next battery you buy was made from the same kinds of ingredients found in your body? That’s the idea behind a breakthrough battery material made from natural, biodegradable components. It’s so natural, it could even be consumed as food.

An international collaboration of astronomers, including researchers from the University of Toronto, have detected the brightest Fast Radio Burst (FRB) to date—and have been able to pinpoint its location in a nearby galaxy by using a network of radio telescopes.

FRBs are extremely energetic flashes from distant sources from across the universe that are caused by extreme astrophysical phenomena...

Your pancreas may be making its own version of Ozempic

Alpha cells in the pancreas can produce GLP1, not just glucagon, offering a surprising backup system for blood sugar control.

Duke University scientists have discovered that pancreatic alpha cells, long believed to only produce glucagon, actually generate powerful amounts of GLP-1 — the same hormone mimicked by popular diabetes drugs like semaglutide (Ozempic and Wegovy). Even more surprisingly, when glucagon production is blocked, alpha cells “switch gears” and boost GLP-1 output, enhancing insulin release and blood sugar control.

A new study from Duke University School of Medicine is challenging long-standing views on blood sugar regulation — and pointing to a surprising new ally in the fight against type 2 diabetes.

Chandra finds black hole that’s growing at 2.4 times the Eddington limit

An artist's concept of a supermassive black hole, a surrounding disk of material falling towards the black hole and a jet containing particles moving away at close to the speed of light. This black hole represents a recently-discovered quasar powered by a black hole. New Chandra observations indicate that the black hole is growing at a rate that exceeds the usual limit for black holes, called the Eddington Limit. Credit: NASA/CXC/SAO/M. Weiss
