An international team, led by Paul R. Fortin of Université Laval, has just identified three markers that would allow for establishing, right at the time of diagnosis, the risk of a lupus ...

Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection. For example, they make it possible to synthesize chemicals in a more ...

Far from Earth's gravitational pull, a simple viral infection took on a new evolutionary direction. A study conducted aboard the ISS found that when bacteria and ...

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic ...

Garter snakes can survive being frozen solid for hours. Here’s how evolution, biochemistry and behavior have allowed them to ...

Cannabis has been part of human culture for thousands of years, yet the molecular machinery that gives the plant its ...

“You see it move its eye,” says Dorota Skowronska-Krawczyk, an associate professor at UC Irvine. “The shark is tracking the ...

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...
