Scientists have discovered that E-cadherin, a protein best known as the glue holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and m...

Researchers found that just 20 minutes of comfortable walking can rapidly stimulate the gut. Within one to two minutes after exercise, bowel sounds became stronger, more frequent, and lasted longer, suggesting increased ...

A particle collider experiment just revealed something unexpected about how the fiery soup of particles that filled the universe after the Big Bang coalesced into the protons and neutrons that make up matter today.

Schadenfreude, or pleasure at seeing another's pain, is a complex emotion. So can animals besides humans experience it?

A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of...

Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed th...

When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern. Wavefront shaping ma...

A 30-year forestry experiment in Australia found that heavily thinned mountain ash forests grew unusually large trees while recovering enough carbon to match or exceed untouched areas. The results suggest carefully manag...

A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain a...

High-dose vitamin B3 is showing intriguing early promise as an addition to standard glioblastoma treatment, with 82% of patients in a small trial remaining progression-free after six months. Researchers believe niacin ma...
