Using alcohol to cope with stress when young may permanently alter the brain, making it harder to adapt to challenges and increasing the risk of returning to drinking later in life. Researchers also found signs of brain damage associated with early dem…

Some brains appear to fight back against Alzheimer’s by helping immature brain cells survive damage instead of succumbing to it. Understanding this natural resilience could point researchers toward entirely new ways to protect memory and slow dementia.

A new study found that not all geoengineering ideas are created equal. Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to global weather patterns, while stratospheric aerosol inje…

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system’s arrow of time and even harvest energy from the measurement process itse…

An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may finally be within reach of discovery. If confirmed, they could solve one of astronomy’s greatest mysteries by explaining the nat…

Bumble bees astonished researchers by inventing a new way to reach a hidden reward, despite never being taught the trick. The discovery adds to growing evidence that these tiny insects are far smarter and more adaptable than once believed.

A protein called “Mitch” may hold the key to a new generation of obesity treatments. Researchers found that disabling it in human cells boosts fat burning, increases energy use, and makes it harder for new fat cells to develop. The findings help explai…
