Researchers have solved the decades-old mystery behind how a common pregnancy drug lowers blood pressure. It turns out the medication blocks a fast-acting "oxygen alarm" inside cells. That same alarm helps brain tumors survive, meaning the drug ...

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 ...

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, ...

Younger women are being diagnosed with breast cancer more often than screening guidelines anticipate. Many of these cancers are invasive and harder to treat, especially in those under 40. After analyzing 11 years of data, researchers found that this ...

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 ...

A high-speed "zap-and-freeze" method is giving scientists their clearest view yet of how brain cells send messages. By freezing tissue at the instant a signal fires, researchers revealed how synaptic vesicles behave in both mouse and human neurons. . ...

A large study of brain scans shows that our neural wiring evolves through five major stages from birth to late old age. These phases are separated by sudden turning points that mark big shifts in how the brain is organized. The most surprising ...
