Women may be especially sensitive to the effects of common dementia risk factors, according to a new UC San Diego study of over 17,000 adults. Researchers say tailoring prevention strategies specifically for women could be key to reducing Alzheimer’s risk.

A newly identified enzyme called IDOL could become a major new target in the fight against Alzheimer’s disease. Researchers found that removing it from neurons sharply reduced amyloid plaques and improved key brain processes linked to resilience and communication between cells. The discovery may lead to future treatments that go beyond slowing Alzheimer’s — potentially helping protect the brain from further decline.

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense internal strain they contain. By using photocatalysis and carefully tuning the starting molecules, the team managed to guide the reaction into a clean and efficient pathway.

Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up using significantly more opioid medication to cope. Researchers say vitamin D may help regulate how the body processes pain through its effects on inflammation and the immune system.

Scientists have discovered that a topical anti-aging drug called ABT-263 can dramatically improve wound healing in older skin. The treatment works by removing damaged “senescent” cells that accumulate with age and slow the body’s repair process. In aged mice, wounds healed much faster after treatment, while the drug also activated genes tied to collagen production and tissue regeneration.

Scientists have identified a protein that appears to put the brakes on the chronic inflammation linked to aging. Older mice with boosted levels of the protein were stronger, more energetic, and had healthier bones than untreated mice. Researchers say the findings could eventually lead to therapies that help people stay healthier and more independent later in life.

People who lost significant weight while taking Ozempic, Wegovy, Mounjaro, or Saxenda had sharply lower risks of major obesity-related health problems, including sleep apnea and kidney disease. Those who gained weight instead faced higher risks — especially for heart failure — even though many patients discontinued the medications within a year.

A large European study revealed that a lower-calorie Mediterranean diet paired with exercise and coaching dramatically reduced the risk of type 2 diabetes. Participants who made these lifestyle changes were 31% less likely to develop the disease over six years. They also lost more weight and trimmed their waistlines compared to those following a standard Mediterranean diet alone.

Scientists have uncovered a hidden “sugar code” on the surface of human cells that could transform how diseases are detected. Using an advanced imaging technique called Glycan Atlasing, researchers at the Max Planck Institute mapped the tiny sugar structures coating cells and discovered that these patterns shift depending on what the cell is doing. Immune cells changed their sugar layouts when activated, and cancerous tissues displayed distinct surface signatures compared to healthy tissue.

Scientists discovered that eating grapes can actually change how your skin behaves at the genetic level. After just two weeks of daily grape consumption, volunteers showed signs of improved skin protection and reduced oxidative stress from UV exposure. Researchers say the effects appear widespread, even though every person’s genes responded a little differently.
