How often do people really fart? Scientists built smart underwear to find out

How often do people really fart? Scientists built smart underwear to find out

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 day—much higher than previous estimates. The device gives scientists a new way to track gut microbial activity in everyday life. It will power a new nationwide study called the Human Flatus Atlas to map normal patterns of gas production.

A lab mistake at Cambridge reveals a powerful new way to modify drug molecules

A lab mistake at Cambridge reveals a powerful new way to modify drug molecules

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment.

Study finds two types of colon polyps can raise bowel cancer risk fivefold

Study finds two types of colon polyps can raise bowel cancer risk fivefold

Researchers studying over 8,400 colonoscopies discovered that having both adenomas and serrated polyps in the bowel can raise the risk of serious precancerous changes by up to five times. These two polyp types may represent separate cancer pathways that can occur at the same time. Nearly half of patients with serrated polyps also had adenomas, making this high-risk combination more common than expected. The results emphasize the importance of early detection and regular colonoscopy monitoring.

Severe COVID or flu may raise lung cancer risk years later

Severe COVID or flu may raise lung cancer risk years later

A severe case of COVID-19 or influenza could increase the risk of lung cancer later on, according to new research. Scientists discovered that serious viral infections can alter immune cells in the lungs, leaving behind chronic inflammation that may help tumors develop months or years later. The increased risk was seen mainly after severe infections that required hospitalization. Vaccination, however, appears to prevent the dangerous lung changes.

Monty Python Got It Wrong About Medieval Disease

Monty Python Got It Wrong About Medieval Disease

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 unexpected: even people with stigmatized diseases like leprosy were buried in these high-status spots. Instead of excluding the sick, many communities appear to have treated them much like everyone else.

A “mirror” molecule can starve cancer cells without harming healthy cells

A “mirror” molecule can starve cancer cells without harming healthy cells

Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, this molecule—called D-cysteine—is taken up mainly by some cancer cells through a specific transporter on their surface. Once inside, it shuts down a crucial mitochondrial enzyme that cancer cells rely on to produce energy and maintain DNA, effectively halting their growth.

Jen Hendershott Is Building the Bridge Women’s Fitness Always Needed

There’s a strange irony in women’s fitness. It may be the most complete division in the IFBB as far as strength, muscle, conditioning, choreography, stage presence, and athleticism go; it is the very embodiment of the fitness movement—and yet it has always lived just slightly in the shadows of its more muscular, less athletic cousins.

The Grease the Groove Training Method: How Frequent Training Builds Serious Strength

The Grease the Groove Training Method: How Frequent Training Builds Serious Strength

Most lifters view strength as if it were all about the muscles. Bigger chest and glutes, and more “time under tension.” And sure, muscle matters. But strength doesn’t start there; it starts in your brain. The brain sends the command, the muscle carries it out, and the clearer that signal becomes, the stronger you get. […]
