One of the largest obstacles limiting the next generation of computer chips may finally have a solution. The shrinking of computer chips has exposed a stubborn problem: even when a semiconductor can carry electricity efficiently, getting that electricity into the material can waste power and slow the device down.

Scientists Overcome a Major Electrical Bottleneck in Next-Generation Semiconductors
One of the largest obstacles limiting the next generation of computer chips may finally have a solution. The shrinking of computer chips has exposed a stubborn problem: even when a semiconductor can carry electricity efficiently, getting that electricity into the material can waste power and slow the device down.

Mysterious Radio Beacon Near a Black Hole Defies Expectations
A black hole in a relatively nearby galaxy has abruptly switched on a powerful cosmic beacon, and years later, it is still blazing. Astronomers have discovered a galaxy whose central black hole has remained extraordinarily bright in radio waves for more than eight years after its emission suddenly increased by more than 20 times. Located […]
A 24-Hour Fast Activates a Microbial Pathway That Helps Heal the Gut
A gut bacterium appears essential to the intestinal repair benefits linked to fasting before radiation. During radiation treatment for abdominal cancer, the therapy aimed at a tumor can also injure the delicate lining of the small intestine. That damage can lead to severe digestive problems and may restrict how much radiation a patient can safely […]

The Hidden Tradeoff Behind Today’s Most Powerful Weight-Loss Drugs
Researchers say treatment decisions should be individualized by weighing expected benefits, potential harms, treatment burden, cost, availability, and patient preferences. A person taking an obesity drug may see a substantial drop on the scale after a year, yet experience little meaningful improvement in daily quality of life. The same treatment may also bring stomach and […]
Morning Glories May Be Losing the Race Against Climate Change
A study suggests that severe pollinator losses may have sharply slowed plant adaptation. A morning glory facing a warmer climate may benefit from blooming earlier. But if pollinators are becoming harder to attract, producing larger flowers may matter more. New research suggests that these competing pressures have become linked in a way that sharply limits […]
