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
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
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
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.
After several quieter years, wildfires have returned to western Greenland.
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
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
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 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
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
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 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
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.
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.
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
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,
Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.
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.
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 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
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.
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
The rockets’ red glare have nothing on these images from Chandra X-ray Observatory
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 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
Physicists have developed a new optical centrifuge that can precisely spin molecules inside a superfluid for the first time. The advance could help unravel some of the biggest mysteries of quantum liquids and reveal how superfluidity breaks down at the atomic scale.
Europe is still taking stock of a powerful heat wave in late June, but experts are already confident it ranks among the worst ever recorded—even rivaling a freak 2003 episode.
Yeast has been growing in the guts of a frozen mummy called Oetzi the Iceman for thousands of years, scientists have discovered, telling AFP they used it to make a tasty sourdough bread.
Costa Rican scientists may have discovered a new species of ghost shark in Pacific waters near Cabo Blanco and Cano Island.
A punishing heat wave threatened America's July Fourth celebrations, World Cup matches and power grids as near-record temperatures scorched the eastern United States on Friday.
