Using NASA's Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, ...

As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing and other applications. However, breaking ...

Ichthyosaurs ruled the oceans for 150 million years during the Mesozoic Era. Their fish-shaped bodies were built for high speeds. In that context, it is normally an advantage to be as light as possible.

The human body fights staph infections by starving it of essential nutrients. Staph, it turns out, is remarkably good at changing what's on the menu. Staphylococcus aureus—the infamous agent behind MRSA and most staph infections—needs ...

Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While the endpoint of this bump is well understood, its onset has remained elusive. Now, in a paper published ...

University of Missouri researchers are paving the way as artificial intelligence transforms biomedical research. A team from the College of Engineering and collaborators recently published one of the most comprehensive reviews ...

Researchers have captured the moment two DNA molecules zip together, overcoming their identical negative charges to pair up and revealing a mechanism that has puzzled scientists for more than 20 years. Using high-powered ...

From targeted cancer treatments to self-healing materials and microscopic robots, many emerging technologies depend on molecules that can be controlled with light. Researchers at Tohoku University have now developed a way ...

(Fe0.63Ni0.3Pd0.07)3P, or FNPP, is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with ...

Indonesia's Mount Anak Krakatau has erupted again this week, sending plumes of volcanic ash high into the sky and disrupting hundreds of flights. More than 300,000 passengers have been affected.

Estuaries across the United States are facing the same trends of warming waters, algal growth and declining oxygen concentrations that threaten water quality and fish populations, regardless of geographic location, according ...

Cornell researchers have used artificial intelligence to uncover a previously unknown way cells control how proteins move inside them, a process essential for growth, communication and movement that is often disrupted in ...
