Scientists discover how deep sleep builds muscle, burns fat, and boosts the brain

Scientists have discovered a surprising two-way relationship between sleep and growth hormone, revealing how the brain carefully balances physical recovery with wakefulness. The findings could help explain why poor sleep harms metabolism and brain health, potentially opening the door to new treatments for sleep and neurological disorders.

Brain cells meant to protect us may be fueling cognitive decline

Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve fibers and potentially contributing to worsening memory and thinking skills.

A protein that fuels cancer could also be the key to fighting it

Scientists have discovered how to turn a protein that normally fuels cancer growth into a weapon against it. By activating PPARD in immune cells, researchers made them better at burning fat and attacking tumors, slowing or stopping cancer growth in laboratory experiments. The approach showed promise against colorectal, breast, and ovarian cancers, as well as melanoma.

USC scientists discover how to create a never-ending supply of cancer-fighting cells

USC scientists have discovered a way to create a potentially renewable supply of genetically engineered immune cells that can attack cancer and strengthen the body's natural defenses. By growing and modifying immature immune cells rather than mature ones, researchers developed a system that can continuously produce tumor-fighting cells inside the body.

Yale scientists discover how stress changes the brain to make memories stronger

Yale scientists have uncovered how the stress hormone cortisol helps the brain turn emotional experiences into stronger, longer-lasting memories. The discovery reveals that stress can reshape communication between brain networks involved in emotion and memory, potentially explaining why certain moments are so difficult to forget.

Eating late at night linked to up to 30% higher risk of liver disease

Eating late at night could be putting your liver at risk, according to a large study led by Oregon Health & Science University. Researchers analyzed data from nearly 200,000 people and found that those who regularly ate after dinner or around bedtime had a 20% to 30% higher risk of liver disease, including fatty liver disease and cirrhosis.

Strokes have nearly doubled among younger adults, and scientists aren't sure why

Strokes are becoming alarmingly common among younger adults, with rates nearly doubling among people ages 20 to 54 over nearly three decades. Researchers found that blocked blood vessels in the brain accounted for much of the increase, while high blood pressure, diabetes, and substance use also became more common among younger stroke patients. Although survival rates have improved, more young adults may now face the lasting consequences of stroke.

Scientists discover a surprising danger in smaller cancer cells

Scientists have discovered that unusually small cancer cells carrying extra chromosomes can be far more aggressive than larger ones, growing faster, spreading more readily, and resisting common treatments. The surprising finding could help explain why some tumors are especially dangerous and provide a new way to predict cancer outcomes.
