Hidden beneath Arctic waters, beluga whales have long kept their family lives a mystery. By analyzing DNA from more than 600 belugas in Alaska's Bristol Bay over 13 years, researchers uncovered a surprisingly flexible mating system: both males and .. ...

Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum effect in an advanced material. The effect can turn alternating electrical signals from the environment directly into the kind . ...

Scientists have uncovered a surprising new way the immune system fights cancer, overturning a core belief that has guided immunology for decades. The research found that when cancer cells shut down a key immune-recognition molecule called MHC I--a .. ...

NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon ...

June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus . ...

Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms. Their experiments revealed that the way vaporized materials cool can dramatically . ...

A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss--they could also fight addiction itself. Researchers found that people taking these ...

Scientists have developed an experimental diabetes and obesity pill that works in a completely different way from drugs like Ozempic. Rather than reducing hunger, it activates metabolism in skeletal muscle, helping lower blood sugar and increase fat ...

A newly identified group of amygdala neurons appears to play a central role in anxiety and social behavior. Restoring normal activity in this tiny brain circuit reversed anxiety and social deficits in mice, revealing a promising new target for future ...

Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years. The finding could open new possibilities for controlling ocean currents, improving medical technologies, . ...
