Sparkling water is often seen as a simple, healthy drink—but could it also help with weight loss? New research suggests it may slightly boost how the body processes blood sugar and energy. However, the effect is very small, meaning it’s no ...
Scientists have discovered that a protein linked to cell death is secretly driving the aging of blood stem cells in a completely different way. Instead of killing the cells, it damages their mitochondria, sapping their energy and weakening the ...
A rogue set of “zombie” immune cells may be driving aging and fatty liver disease by flooding tissues with inflammation. Researchers found these cells accumulate with age and high cholesterol—and can make up most of the liver’s immune cells ...
Spending time with close companions might do more than strengthen bonds—it could also reshape your gut bacteria. In a study of island birds, those with stronger social ties shared more gut microbes, especially types that require direct contact to ...
Public restrooms might seem like a germ nightmare, but the real risks aren’t always where you think. While toilet seats can carry bacteria, viruses, and even parasite traces, studies show they’re often cleaner than high-touch surfaces like door ...
For years, scientists believed our lifespan was mostly shaped by environment and chance, with genetics playing only a minor role. But a new study from the Weizmann Institute flips that idea on its ...
A newly discovered molecule could reshape the future of weight loss treatments by mimicking the powerful appetite-suppressing effects of drugs like Ozempic — but without many of the unpleasant side effects. Identified using artificial ...
A new study reveals that popular diabetes and weight-loss drugs like Ozempic and Wegovy may not work as effectively for about 10% of people due to specific genetic variants. These individuals appear ...
A major study suggests that when you eat could play a key role in staying lean. People who fast longer overnight and start their day with an early breakfast were more likely to have a lower BMI years later. Scientists think this is because eating ...
Scientists searching for air pollution clues stumbled onto something unexpected: toxic MCCPs drifting through the air for the first time in the Western Hemisphere. The likely source—fertilizer made from sewage sludge—points to a hidden route for ...
Scientists have achieved the unthinkable by stabilizing a highly reactive molecule in water, confirming a decades-old theory about vitamin B1’s role in the body. The breakthrough not only solves a scientific mystery but could revolutionize greener ...
Losing your sense of smell might signal Alzheimer’s far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in ...

A deadly parasite responsible for sleeping sickness has been found using a surprisingly precise trick to stay hidden in the human bloodstream. Scientists discovered a protein called ESB2 that acts ...

Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send ...

Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece ...

Flower nectar often contains small amounts of alcohol, meaning pollinators like hummingbirds are drinking it all day long. Despite consuming human-equivalent amounts, they show no signs of ...

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining ...

The largest review of medicinal cannabis to date found it doesn’t effectively treat anxiety, depression, or PTSD—despite millions using it for those reasons. Researchers warn it could even make ...

Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of ...

A surprising breakthrough suggests that a drug best known as Viagra could help treat a devastating childhood disease. Researchers found that sildenafil significantly improved symptoms in patients ...

Scientists have mapped the genetics of cancer in cats for the first time at scale, uncovering major overlaps with human cancers. Key mutations—like those linked to breast cancer—appear in both ...

Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the ...

In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something ...

Researchers have created “Smart Underwear,” a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a ...

Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia ...

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — ...

A new study reveals that high doses of antioxidants—often seen as harmless or beneficial—may actually impact future generations. Male mice given common supplements like NAC produced offspring ...

Researchers have mapped the genetic risk of hemochromatosis across the UK and Ireland for the first time, uncovering striking hotspots in north-west Ireland and the Outer Hebrides. In some regions, ...

An Ice Age double burial in Italy has yielded a stunning genetic revelation. DNA from a mother and daughter who lived over 12,000 years ago shows that the younger had a rare inherited growth ...

Colorblindness may be doing more than making traffic lights confusing — it could also be hiding a life-threatening warning sign. Researchers analyzing millions of medical records found that people ...

Plants make chemical weapons to protect themselves, and many of these compounds have become vital to human medicine. Researchers found that one powerful plant chemical is produced using a gene that ...

Some people get drunk without drinking because their gut bacteria produce alcohol from food. Researchers have now identified the microbes and biological pathways behind this rare condition, ...
