Europa's subsurface ocean might be getting fed after all. Scientists found that salty, nutrient-rich surface ice can become heavy enough to break free and sink through Europa's icy shell, delivering essential ingredients to the ocean below. The ...

Chemists at UCLA are showing that some of organic chemistry's most famous "rules" aren't as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds--structures long considered impossible--the team is opening . ...

A new study suggests humans belong in an elite "league of monogamy," ranking closer to beavers and meerkats than to chimpanzees. By comparing full and half siblings across species and human cultures, researchers found that long-term pair bonding is . ...

Researchers have identified a promising new weapon against triple-negative breast cancer, one of the most aggressive forms of the disease. An experimental antibody targets a protein that fuels tumor growth and shuts down immune defenses, effectively ...

Type 2 diabetes becomes more dangerous to the heart the longer a person has it. Researchers found that after several years, red blood cells can begin interfering with healthy blood vessel function. This harmful shift was not present in newly ...

A new blood test may reveal Crohn's disease years before symptoms begin. The test detects an unusual immune response to gut bacteria in people who later develop the condition. By studying healthy relatives of Crohn's patients, researchers identified ...

A new study reveals that super agers over 80 have a distinct genetic edge. They are much less likely to carry the gene most associated with Alzheimer's risk, even when compared with other healthy seniors. Researchers also found higher levels of a ...

Scientists found that nasal cells act as a first line of defense against the common cold, working together to block rhinovirus soon after infection. A fast antiviral response can stop the virus before symptoms appear. If that response is weakened or ...

Scientists studying genetic data from over a quarter million people have uncovered new clues about what controls how fast the gut moves. They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and ...

Blockchain could make smart devices far more secure, but sluggish data sharing has held it back. Researchers found that messy network connections cause massive slowdowns by flooding systems with duplicate data. Their new "Dual Perigee" method lets .. ...
