Losing your sense of smell might signal Alzheimer's far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in early ...

Researchers have uncovered why a rare blood clotting disorder can occur after certain COVID-19 vaccines or adenovirus infections. The immune system can mistakenly target a normal blood protein (PF4) after confusing it with a viral protein. This ...

Alzheimer's isn't just one problem--it's a tangled mix of biology, aging, and overall health. That's why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward multi-pronged . ...

A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it's safe, ...

Scientists have proposed a surprising new way to detect gravitational waves--by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The ...

A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance--but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a .. ...

Cancer drugs known as BET inhibitors once looked like a breakthrough, but in real patients they've often fallen short. New research reveals a key reason why: two closely related proteins, BRD2 and BRD4, don't actually do the same job. Instead, BRD2 . ...

A breakthrough in microbiome research could change how colorectal cancer is detected--no colonoscopy required. Scientists used AI to map gut bacteria at an unprecedented level of detail, revealing subtle microbial patterns linked to cancer. By ...

Earth's nights are steadily getting brighter overall, but the changes vary dramatically by region. Rapid urban growth is lighting up countries like China and India, while parts of Europe are dimming due to energy-saving efforts and new lighting ...
