Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ALMA telescope in Chile, researchers conducted .. ...

Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second. Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry.

Songbirds appear to have evolved through rare explosions of change separated by long periods of slower development. Many of those bursts lined up with major climate shifts, suggesting that environmental upheaval can reshape life in powerful ways.

Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus ...

Bumblebees naturally have short lives, but extreme heat and human activity are making survival harder. Pesticides can poison bees or destroy the flowers they depend on, while habitat loss leaves them with fewer safe places to live and feed. ...

Rice University chemists have found a new way to make neodymium, a rare-earth metal, interact with oxygen. Using a specially designed molecular structure described as a "basket," the team positioned the atoms so they could form a bond once thought .. ...

A new cooking method could make French fries crispier in less time while significantly limiting how much oil they absorb. Researchers propose combining microwave heating, which keeps oil out, with conventional frying, which provides the crunch ...

Christof Koch is taking on one of science's deepest mysteries: how the brain creates conscious experience, or whether it creates it at all. He argues that materialism has yet to solve this "hard problem" and will explore puzzling phenomena such as .. ...

Sleeping well during a heatwave starts with stopping the home from overheating. Close blinds against strong sunlight, ventilate when the air outside becomes cooler, and avoid using heat-producing appliances during the hottest hours. Moving to a ...

Europa's hidden ocean has made the icy moon one of the solar system's most promising places to search for habitable conditions. Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future .. ...
