Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...

A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view ...

Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.

A new study, led by researchers from the University of Tokyo, involving nearly 1,000 patients in Japan suggests that attention deficit hyperactivity disorder (ADHD)-related traits may be associated with and may contribute ...

Eastern Africa's Turkana Rift is both a hotbed for fossil discoveries of our earliest ancestors and a literal hotbed of volcanic activity caused by shifting tectonic plates. Now researchers have found that Earth's underlying ...

How do cells know when to activate or slow down their activity? A team from the University of Geneva (UNIGE) provides new insights by studying TORC2, an essential but still poorly understood protein complex. Using ultra-high-resolution ...

Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new ...

NASA's Curiosity Mars rover has uncovered a diverse mix of organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.

Marburg virus disease (MVD) is a severe and often fatal hemorrhagic disease in humans caused by the Marburg virus. It is carried by Egyptian fruit bats and can spread to people after exposure in caves or mines where they ...

Every year, the countries competing in the International Mathematical Olympiad arrive with a booklet of their best, most original problems. Those booklets get shared among delegations, then quietly disappear. No one had ever ...

Chicken eggs are already used to harvest helpful proteins called antibodies to protect humans from viruses such as influenza. Now, a breakthrough at the University of Missouri could one day lead to chickens that produce other ...
