Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other。 Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able to encourage healthier bacteria while reducing dise
A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease。 Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the disease。 In animal models, oral arginine not only lowered harmful protein deposits but also impro
A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease — a condition that affects millions and often leads to dialysis。 In a clinical trial involving 150 patients, researchers found that lubiprostone, a medication normally used to treat constipation, helped preserve kidney function in people with moderate
Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough。 The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief。 In experiments involving chronic itch similar to eczema, mice missing this signal scratched le
Eating eggs might do more than just start your day—it could help protect your brain。 Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27% reduction。 Even modest egg intake showed benefits, suggesting that small
Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease。 A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced。 Eve
Blood glucose levels can be a reliable indicator of diabetes risk。 But in some populations, it's not enough to catch the disease early
Long before humans spread across the globe, a deadly disease may have quietly shaped where our ancestors lived—and even how we evolved。 New research reveals that malaria didn’t just threaten early human survival; it actively pushed populations away from high-risk regions across Africa, fragmenting groups over tens of thousands of years。 This separa
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects。 By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding。 This could transform fields like
