Scientists discover the deep sleep circuit that builds muscle, burns fat, and boosts the brain

Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain why poor sleep can interfere with growth, muscle repair, fat metabolism, and brain function. Understanding this system could pave the way for new therapies for sleep disorders and diseases tied to metabolism and the brain, including Alzheimer's and Parkinson's.

NASA's Hubble spots a stellar sparkler for the Fourth of July

NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped transform the young universe into one capable of forming planets and, eventually, life.

NASA's Hubble captures a crimson stellar nursery sparkling with blue and white stars

Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in gas and dust for millions of years, extending an important stage of stellar development. The region also contains multiple generations of stars living side by side, offering fresh clues about how star formation unfolds over time.

NASA's Hubble captures a star-spangled sea of 500,000 stars

Celebrating the United States' 250th anniversary, NASA released a stunning Hubble portrait of Messier 3, an ancient globular cluster with more than 500,000 stars. The remarkable cluster is helping scientists unravel the Milky Way's past thanks to its rare stars and possible origins in a long ago cosmic merger.

Scientists may have finally solved the black hole information paradox

Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain. The same seven-dimensional geometry behind this idea could also help explain why elementary particles have mass.

The secret to healthy aging may be hidden in your blood

Some people live past 100 with remarkable health, and researchers may have uncovered one reason why. A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual patterns of bile acids and steroids linked to longer survival.

A hidden weakness in deadly cancers could lead to powerful new treatments

A UCLA study has identified a hidden Achilles' heel in aggressive small cell cancers that have resisted new treatments for decades. Scientists found that tumors lacking the RB gene become critically dependent on the protein E2F3 for survival. Blocking E2F3 shut down tumor growth in laboratory models, and existing FDA-approved drugs may be able to exploit this vulnerability. The discovery could pave the way for faster development of more effective therapies.

Drinking to cope with stress may permanently rewire your brain

Using alcohol to cope with stress when young may permanently alter the brain, making it harder to adapt to challenges and increasing the risk of returning to drinking later in life. Researchers also found signs of brain damage associated with early dementia, suggesting the effects can linger long after alcohol use has stopped.

A popular climate fix could accidentally trigger massive changes to global weather

A new study found that not all geoengineering ideas are created equal. Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to global weather patterns, while stratospheric aerosol injection left the system largely unchanged. Researchers say the results are a reminder that efforts to cool the planet could produce unexpected consequences if they are deployed without a full understanding of how Earth's climate works.

The real cause of a common stroke may have been missed for decades

Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged and damaged blood vessels deep within the brain. The finding helps explain why standard treatments like aspirin are often less effective and is driving the search for new therapies that target the brain’s tiny blood vessels directly.
