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 ...
Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to ...
A natural compound found in foods such as spinach, almonds, and sweet potatoes may aggravate gut inflammation in people with Crohn’s disease and ulcerative colitis because their intestines appear to handle it differently. Researchers say the ...
Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways ...
A remarkably detailed study of Maria Branyas, who lived past 117, reveals that extreme longevity may involve both intense aging and powerful biological protection at the same time. Researchers found signs of advanced aging, but also low ...
Scientists found that caffeine activates an ancient cellular energy system involved in stress resistance, DNA repair, and growth. The discovery could help explain caffeine’s links to healthier aging and may point toward new ways to target the same ...
A large study of nearly 74,000 men suggests that long-term use of tadalafil, best known as Cialis, may be linked to a higher risk of glaucoma and other eye pressure problems. Men prescribed the drug for urinary symptoms caused by an enlarged ...
A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow ...
Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was linked to ...
Mindfulness, gratitude, and optimism training may improve blood pressure, inflammation, and other heart-health measures within just eight to 12 weeks. The strongest programs paired daily practice with regular reinforcement, suggesting that improving ...
Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of ...
Common medications may reshape the gut microbiome long after the last dose is taken. In a study of more than 2,500 people, researchers found lasting microbial changes linked not only to antibiotics, but also to antidepressants, beta-blockers, ...

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in ...

A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently ...

Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early ...

A Rutgers study suggests GLP-1 drugs such as Ozempic and Wegovy may weaken the link between impulsive tendencies and violent behavior. The surprising finding hints that these medications could affect ...

An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression. In a small clinical trial, people with a history of ...

What if Sigmund Freud was onto something that modern neuroscience is only now beginning to explain? A new paper argues that today's leading theory of the brain—as a prediction machine ...

Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence ...

Feeling constantly drained might not just be about poor sleep or working too hard. Researchers in Japan found that low levels of key vitamins — especially vitamin B12 and folate — may quietly ...

A specially formulated tomato-soy juice packed with natural plant compounds may help calm inflammation linked to obesity, according to a new clinical study. Healthy adults with obesity who drank the ...

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 ...

For years, “yo-yo dieting” has been blamed for wrecking metabolism and causing lasting damage, but a major new review says the fear may be wildly overblown. After analyzing decades of studies in ...

A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in ...

Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells ...

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own ...

A new minimally invasive procedure may help people keep weight off after stopping popular drugs like Ozempic and semaglutide—something most patients struggle with. In a clinical trial, those who ...

Coffee doesn’t just energize—it actively reshapes the gut and mind. Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. ...

Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged ...
