A new clinical study suggests that successful root canal treatment may benefit more than just dental health. Patients treated for infected teeth showed improved blood sugar control, healthier cholesterol levels, and reduced inflammation over time. .. ...

Melatonin is now widely used to help children sleep, but scientists say the enthusiasm may be getting ahead of the evidence. A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical . ...

A major clinical trial has delivered an unexpected twist in the search for ways to fight COVID-19 and its lingering effects. Researchers at Mass General Brigham found that taking high doses of vitamin D3 did not make COVID-19 infections less severe . ...

When the Asian financial crisis sent rice prices soaring in Indonesia in the late 1990s, the shock didn't just strain household budgets--it left lasting marks on children's bodies. Researchers from the University of Bonn found that kids exposed to .. ...

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, ...

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 .. ...

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 ...

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 ...

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 ...
