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…

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…

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…

NIH-funded, automated clinical decision support could facilitate timely interventions for at-risk patients years before they might otherwise seek help.

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Scientists…

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal…

A newly identified Australian tree has been dubbed the “zombie” tree because it’s alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow disease…

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…

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic switches…

Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new research shows that moving cells inside the follicle actually pull the hair upward like a microscopic motor. Advanced 3D imaging revealed…

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…

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems—and scientists barely know how they’re doing. Researchers found that nearly 90% of North America’s insect and arachnid species have no conservation status, leaving…

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that TDP43 controls a key DNA repair process, but when the protein becomes imbalanced, the repair system can spiral out of control, harming…

Hidden in volcanic lakes and deep-sea vents, scientists have discovered tough new DNA-binding proteins built to survive extreme conditions. After scanning huge genetic databases, researchers found molecules that remain stable under heat, salt, and harsh chemistry.…

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that activate…
