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
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
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
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
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.
'This was something new': What people in Greenland told us about learning to live with wildfires
After several quieter years, wildfires have returned to western Greenland.
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
How proteins are inserted into cell membranes
Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins into their cell membranes. They explain
Planned 1.7 million satellites 'devastating' for astronomy: Study
The 1.7 million satellites that companies are aiming to launch into Earth's orbit in the coming years will have "devastating consequences for astronomy," new research warned Wednesday.
When companies face hostile takeover threats, they turn to ESG, and the whole community benefits
When a company faces the prospect of a hostile takeover, its board may reach for traditional anti-takeover defenses. "Poison pills," for instance, allow existing shareholders to buy additional shares at a discount, diluting a would-be acquirer's stake and making the target more
Optical writing of antiferromagnets points toward new storage devices and energy efficient information systems
A German-Japanese research team involving the University of Augsburg has made a significant breakthrough in the use of antiferromagnets. For the first time, the team has succeeded in writing magnetic information using only ultrashort laser pulses—without the need for electric
Europe's baked rice bowl seeks escape from drought
Summer came too early to Europe's most important rice-growing region, and weeds are taking over Sharon Angoli's parched paddies in Italy's Pavia province.
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
Ancient teeth from Siberia rewrite the plague's timeline, dating back to over 5,500 years ago
Scientists have found the oldest known evidence of the plague, which sparked deadly outbreaks dating back about 5,500 years ago—some 200 years earlier than previously thought.
Common nanostructures may explain shared photoproperties in two widespread dark materials
A newly developed framework for understanding the photoproperties of both natural organic matter and eumelanin, a natural pigment responsible for dark colors in organisms, may inspire advanced sustainable technologies, scientists say.
BC and Alberta fall behind on fracking safety distances for residents
In May, Prime Minister Mark Carney announced plans to double the capacity of Canada's electricity grid by 2050, using natural gas in the name of "powering Canada strong." Almost all Canadian natural gas these days is derived from hydraulic fracturing—known as fracking—an
Greenland meltwater adds to AMOC weakening, but updated model finds no tipping point in sight
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics north and sends colder, deeper water south,
A rare dinosaur fossil from Antarctica is found tucked away in a drawer
Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.
Bacterial protein reveals a hidden rule for controlling calcium
A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny charged particles that can reshape chemical interactions.
Rising seas make once-rare coastal floods 12 times more likely
Extreme floods that once swamped coastal communities only rarely are becoming far more common as climate change caused by humans pushes sea levels higher, according to new research published Wednesday. Experts say the findings are crucial for making plans about floods and
Astronomers may have caught an early galaxy in the process of dying
Astronomers have spotted many "red and dead" galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of becoming dead: a massive galaxy being stripped of its
Trained AI outperforms biologists at spotting salmon lice
Researchers have taken over 120,000 images of salmon lice larvae in seawater and used them to train AI models. The models were much faster and more accurate than experienced biologists at identifying the parasites that feed on the skin and blood of salmonids.
A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults
Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully grown adults with their mature plumage, all set to find
For July 4, NASA unveils an astronomical fireworks show, complete with sound effects
The rockets’ red glare have nothing on these images from Chandra X-ray Observatory
El Nino set to be 'strong', UN warns
El Nino is here and will quickly develop into a strong event between July and September, fueling the likelihood of extreme weather, the United Nations' climate agency warned Friday.
NASA celebrates America's 250th birthday with incredible views of space
NASA is marking the United States' 250th birthday with four striking red, white, and blue images of deep space from the Chandra X-ray Observatory. The collection features an exploded star, a stellar nursery, a galaxy where stars are rapidly forming, and a galaxy cluster that
