Scientists at Johns Hopkins may be closing in on dark matter's elusive trail, uncovering a mysterious gamma ray glow at the heart of our galaxy that could signal unseen matter colliding -- or perhaps the frantic spin of dying stars. Using advanced .. ...

Weight-loss surgery dramatically outperformed GLP-1 medications in improving longevity and reducing heart, kidney, and eye complications for people with obesity and diabetes. Over 10 years, patients lost far more weight and required fewer medications ...

Stanford scientists have solved a long-standing challenge in growing brain organoids by using a simple food additive to keep them from sticking together. The breakthrough enables the production of thousands of identical mini-brains at once, making .. ...

A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. ...

EMBL researchers created SDR-seq, a next-generation tool that decodes both DNA and RNA from the same cell. It finally opens access to non-coding regions, where most disease-associated genetic variants lie. By revealing how these variants affect gene ...

Salk Institute scientists discovered that bile acids in the liver can weaken immune cell function, making immunotherapy less effective against liver cancer. They pinpointed specific bile acids that suppress T cells and found that supplementing with . ...

Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of "proto Earth" material that survived the planet's violent formation. ...

Scientists from NASA and Chalmers University have discovered that incompatible substances can mix on Titan's icy surface, breaking the "like dissolves like" rule of chemistry. Under ultra-cold conditions, hydrogen cyanide can form stable crystals ...

For the first time, scientists observed a black hole tearing apart a star far from its galaxy's center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the initial ...

Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of ...
