Unexpected source of genetic diversity found in human sperm

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the ...

A wandering black hole caught feeding on the run

Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...

New thermal insulator outperforms any material found in nature

Researchers have engineered a new material that is an extreme thermal insulator, is exceptionally stiff and can be printed as a thin film at large scales. The material has one of the lowest thermal conductivity profiles of ...

Physicists take Hall effect in a new direction

Carnegie Mellon University scientists have uncovered a new phenomenon that challenges a longstanding assumption about how electronic materials respond to magnetic fields. The discovery broadens the fundamental understanding ...
