Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer's disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by ...

Quantum mechanics has journeyed from a strange and controversial idea to the foundation of some of humanity's most advanced technologies. Now researchers are pushing its boundaries even further, with potential breakthroughs in energy, medicine, ...

Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain why poor sleep can interfere with growth, muscle ...

Some people live past 100 with remarkable health, and researchers may have uncovered one reason why. A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual ...

A UCLA study has identified a hidden Achilles' heel in aggressive small cell cancers that have resisted new treatments for decades. Scientists found that tumors lacking the RB gene become critically dependent on the protein E2F3 for survival. ...

A new intranasal DNA vaccine may give the immune system an extra weapon against tuberculosis by targeting bacteria that can hide from antibiotics. In animal studies, it helped clear infections faster, reduced lung inflammation, and prevented relapse ...

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 . ...

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 ...

Scientists at UCLA discovered a surprising reason aging muscles heal more slowly. In older muscle stem cells, a protein called NDRG1 builds up and acts like a brake, slowing the cells' ability to jump into repair mode after injury. But there's a ...

Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged and damaged blood vessels deep within the brain. ...
