Mindfulness, gratitude, and optimism training may improve blood pressure, inflammation, and other heart-health measures within just eight to 12 weeks. The strongest programs paired daily practice with regular reinforcement, suggesting that improving ...

Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening embryo to buckle and twist inside the egg. ...

A study of people over 90 found that dementia risk remains strongly shaped by sex, race and genetics, with women and black participants facing notably higher risks. Intriguingly, some people stayed cognitively healthy despite carrying major risk ...

A vast plume rising from deep inside Earth may be responsible for mysterious movements along the East African Rift. The discovery reveals how forces deep in the mantle are working alongside shallower geological forces as the continent slowly pulls .. ...

Rare storms covered huge stretches of Chile's Atacama Desert in snow and dumped extraordinary amounts of rain on one of the driest regions on Earth. The extreme weather shut down observatories, triggered damaging floods and mudflows, and unfolded ...

NASA has brought two of Swift's telescopes back online after technical problems derailed a commercial mission intended to rescue the aging observatory by raising its orbit. With atmospheric drag pulling the spacecraft downward faster than expected, . ...

NASA and SpaceX have delayed Crew-13 after finding an oxidizer leak in the Dragon spacecraft's propulsion system during prelaunch preparations. Engineers are investigating the problem before the four-person crew can begin its journey to the ...

A once-nightly pill cut breathing interruptions by about 44% in a major phase 3 sleep apnea trial, while improving oxygen levels and disease severity. By strengthening the muscles that keep the airway open during sleep, AD109 could offer a new option ...

Scientists discovered that human microglia, immune cells that help shape developing brain circuits, can take four to eight years to mature instead of just weeks as they do in mice. The unusually slow process may help explain how the human brain ...

Researchers discovered a possible way cancer cells hide from the immune system: they build a thick, sugar-rich coating around themselves. High blood sugar can strengthen this protective shield under conditions that resemble the environment inside ...
