Researchers have uncovered three brain pathways linked to lasting improvements in people receiving deep brain stimulation for severe, treatment-resistant depression. They also discovered that patients who failed to improve after two years shared a .. ...

Scientists have uncovered a surprising difference in how male and female skin repairs and renews itself. By tracking individual skin stem cells in living mice for five months, researchers discovered that female cells work together in a highly ...

Scientists have discovered that many common sweeteners can interfere with gut bacteria, with some combinations involving medications producing surprisingly strong effects. One sweetener mixed with a widely prescribed antidepressant reduced beneficial ...

Scientists have discovered that a protein linked to youth helps protect the brain's immune cells from age-related decline. Restoring the protein in older mice improved the cells' ability to clear debris and reduced signs of inflammation, raising ...

Scientists have discovered that a potential new drug can reverse severe fatty liver disease in animal models by restoring gut health and blocking harmful substances from reaching the liver. The breakthrough could pave the way for new treatments for . ...

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 ...

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 .. ...

Stanford scientists have developed a revolutionary microscope that reveals the hidden inner workings of living cells in real time, without the fluorescent labels that can interfere with observations. The breakthrough could provide new insights into . ...

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 ...

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 . ...
