Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions

On October 9, 2022, an intense pulse of gamma-ray radiation swept through our solar system, overwhelming gamma-ray detectors on numerous orbiting satellites, and sending astronomers on a chase to study the event using the ...


Researchers develop technology to protect food's bioactive compounds during digestion

Bioactive compounds present mostly in fruit and vegetables perform different bodily functions relating to health and well-being. Their effects are considered antioxidant, antidiabetic, antiaging and anticancer, among others.

Study finds fish assess misinformation to avoid overreaction

Fish can adjust their sensitivity to the actions of others—such as fleeing due to a false alarm—to reduce the risk of responding to misinformation, according to a new study. Other animals, including humans, may also have ...
