Scientists have identified the genetic cause behind the mysterious AnWj blood group antigen, solving a puzzle that began in 1972 and establishing a new blood group system called MAL. The discovery could make it much easier to find extremely rare ...
Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to future damage, revealing a mechanism that could ...
Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in ...
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while ...
Ozempic and other GLP-1 medications can improve blood sugar, weight, and cardiovascular health, but researchers found little evidence that they also improve mental health, employment, marriage, or overall well-being. The findings suggest the ...
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help ...
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors ...
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new ...
Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an immune ...
Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation ...
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the ...
A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for ...

Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ...

Ancient DNA reveals that plague repeatedly returned to Europe for more than 400 years after the Black Death, evolving into new lineages and spreading through trade, migration, and war. Researchers ...

A major Ontario study found 24 common medication chains in which one drug’s side effects can be mistaken for a new medical problem, leading to another prescription. Researchers say closer ...

Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of ...

Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms ...

UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer ...

Semaglutide, the drug found in Ozempic and Wegovy, was linked to nearly 40% fewer asthma attacks in a large real-world study. It was also associated with about 20% fewer COPD flare-ups. Researchers ...

GLP-1 drugs such as Ozempic, Wegovy, and Zepbound may increase hair-loss risk by 7% in men who are already genetically susceptible to male-pattern baldness. The findings suggest thinning hair may not ...

UCLA researchers have discovered two powerful influences that help guide how the human brain forms before birth. Radial glia, stem cells responsible for producing much of the cerebral cortex, change ...

Semaglutide helped older healthy mice live longer while improving memory, muscle function, blood sugar control, and several biological signs of aging. Its effects went beyond those seen with calorie ...

More than 1,200 genetic variants have been linked to the Big Five personality traits, and many of the same variants are also associated with health, longevity, careers, income, and everyday habits. ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an ...

Scientists in Japan have identified a natural compound found in blueberries, grapes, and other berries that may help muscle cells burn excess fat instead of storing it. The compound, pterostilbene, ...

“Broken heart syndrome” can mimic a heart attack so closely that patients often need invasive testing to tell the difference. Researchers have now developed the BioTAK score, which combines ...

Starting statins soon after a type 2 diabetes diagnosis may do more than protect the heart. In a nationwide Danish study of more than 132,000 people, those who began statin treatment within a year of ...

Heart disease and chronic kidney disease can accelerate one another, but new guidelines say simple screening and early treatment could substantially reduce the risks. Blood and urine tests, combined ...

CAR T-cell therapy dramatically reduced disease activity in six people with severe rheumatoid arthritis that had resisted other treatments, with three achieving medication-free remission. The ...

A ketogenic diet outperformed Mediterranean and low-fat diets in several measures of metabolic health during a clinical trial involving people with obesity, prediabetes, and fatty liver disease. All ...

A wearable device has revealed nighttime hormone surges that may expose a frequently missed cause of high blood pressure. The discovery could help explain why primary aldosteronism often escapes ...

Most men may be missing an important dietary clue about prostate cancer. A new survey found that only 20% knew research has linked dairy consumption with increased prostate cancer risk, while 66% ...
