Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from NASA's Chandra X-ray Observatory and other telescopes, astronomers are piecing together ...

Researchers have developed a method for achieving an order-of-magnitude enhancement of the light emission from a class of two-dimensional (2D) materials called transition metal dichalcogenides (TMDs). The large light enhancement ...

Piezoelectricity (aka the piezoelectric effect) occurs within certain materials – crystals (notably quartz), some ceramics, bone, DNA, and a number of proteins – when the application of mechanical stress or vibration ...

A team of researchers with the Centre for Biological Diversity, School of Biology, University of St Andrews, in the U.K. has found that the seemingly clever wire bending abilities of New Caledonian crow Betty back in 2002 ...

A team of researchers led by Robert Pitman, a marine ecologist with NOOA Fisheries' Southwest Fisheries Science Center, has found evidence that suggests humpback whales may engage in altruistic behavior during encounters ...

NASA's Cassini spacecraft has found deep, steep-sided canyons on Saturn's moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on ...
