- newUSC 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.

- newYale 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.

- 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.

- Scientists discover how exercise reverses muscle aging
Scientists have uncovered a hidden biological mechanism that helps explain how exercise can reverse some of the damage caused by muscle aging. The key is a gene called DEAF1, which becomes overactive with age and interferes with the muscles’ ability to clear damaged proteins and repair themselves. Exercise can help restore this balance, allowing older muscles to rebuild and regain strength, although the benefits may diminish when the system becomes too disrupted.

- Mysterious brain activity under anesthesia challenges what we know about consciousness
Even under general anesthesia, the human brain can analyze language, recognize different types of words, and predict what comes next in a story, according to a surprising discovery by Baylor researchers. The findings challenge our understanding of consciousness and suggest that the unconscious brain is far more capable than scientists previously realized.

- 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.

- 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.

- Rare study reveals a striking divide inside an Alzheimer’s patient’s brain
A rare examination of an Alzheimer’s patient’s brain revealed that regions cleared of amyloid plaques had remarkably little of the harmful tau buildup associated with memory loss, while neighboring areas showed extensive damage. The discovery suggests that removing amyloid may have lasting protective effects and could help slow Alzheimer’s progression, especially when treatment begins early.

- 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.

- Ozempic and Wegovy linked to rare risk of sudden vision loss
Popular diabetes and weight loss drugs such as Ozempic and Wegovy have been linked to a slightly increased risk of a rare condition that can cause sudden, potentially permanent vision loss. Although the risk remains very low, Rutgers researchers say the findings warrant attention as millions of people turn to GLP-1 medications.

- A 47-year study reveals the age when your body starts losing strength
A 47-year study has uncovered a surprising turning point in physical aging: fitness and strength begin declining around age 35, even among people who exercise regularly. Researchers found that this decline accelerates as people get older, but starting to exercise in adulthood can still improve physical performance.

- Cancer is rising in younger adults, and scientists can't fully explain why
A major study found that several cancers are rising faster among younger adults in England, even as smoking, diet, and other established risk factors have generally improved. Excess weight explains only part of the increase, leaving scientists searching for other possible causes, including changes in the gut microbiome and early-life exposures.

- Scientists reveal why some workout recovery tricks can backfire
Ice baths, massages, compression garments, and recovery supplements promise faster muscle recovery, but research suggests their benefits are often overstated, and some techniques may even undermine long-term gains. Scientists say the most effective recovery methods are far simpler and cheaper: getting enough sleep, eating well, and giving muscles time to rebuild.

- Cornell scientists identify rare human genetic disorder in two unusually long-legged cats
Two unusually long-legged cats have helped scientists uncover the first genetically confirmed cases of Marfan syndrome in domestic felines. Researchers at Cornell University discovered that the brothers carried two altered copies of a gene linked to the rare connective tissue disorder, which can affect the eyes, heart, and blood vessels. Surprisingly, the cats survived into adulthood because their genetic mutation still allowed some normal function.

- The secret to easier exercise as an adult may start in childhood
Exercise during childhood could have a surprising lifelong benefit, potentially making physical activity less exhausting in adulthood. In a study involving guinea fowl, researchers discovered that birds accustomed to carrying weights while growing up could carry those weights as adults without using extra energy, while untrained birds burned 23% more.
