Scientists found that combining oxytocin with an Alk5 inhibitor revitalized extremely old male mice, boosting their lifespan and strength. Female mice showed only short-term improvements, highlighting a major sex difference in aging biology. The ...

Scientists have discovered that a single gene, GRIN2A, can directly cause mental illness--something previously thought to stem only from many genes acting together. People with certain variants of this gene often develop psychiatric symptoms much ...

Nitrous oxide may offer quick, short-term relief for people with major depression, especially those who haven't responded to standard medications. The meta-analysis found rapid improvements after a single dose and more sustained benefits after ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light via a vertebrate-like c-opsin. The discovery reveals ...

Archaeologists excavating the ancient Roman city of Gabii have uncovered a massive stone-lined basin that may represent one of Rome's earliest monumental civic structures. Its central placement hints that early Romans were already experimenting with ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and change their orbital behavior. This leads the stars to ...

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea sediments show that ancient Antarctic waters once trapped ...

Dolichospermum, a type of cyanobacteria thriving in Lake Erie's warming waters, has been identified as the surprising culprit behind the lake's dangerous saxitoxins--some of the most potent natural neurotoxins known. Using advanced genome sequencing, ...

Researchers have found a small but powerful switch inside breast cancer cells that helps them survive stressful conditions. When this switch flips, the cells activate protective programs that make them tougher and faster-growing. The finding reveals ...

Scientists have found that common foods can contain hidden contaminants formed during cooking or through environmental exposure. A new testing method called QuEChERS helps identify these chemicals more quickly and with greater ease. The research ...
