Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood ...

October skywatchers can see Saturn at opposition, catch meteors from Halley's Comet during the Orionid peak, and watch the Moon sweep past the famous Pleiades star cluster. Moonlight may obscure some Orionids, but the best viewing should come before ...

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile ...

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that ...

NASA has selected the GIMLI project to investigate whether the Marius Hill Pit opens into a vast underground cave or lava tube. Using radar, seismic sensors, gravity measurements, and cameras, researchers will search beneath the lunar surface and ...

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 mouse embryos, researchers .. ...

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 the mysterious Ordovician ...

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 the formation of hydrogen in the ...

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 managed thinning could support ...

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 aging may appear decades before ...
