Scattered bronze bells in Chinese lord's 2,600-year-old tomb point to ritual deactivation
When archaeologists opened the 2,600-year-old tomb of an ancient Chinese lord, they discovered his magnificent bronze bells had been scattered, their wooden hangings broken. But the most mysterious part of all: This was apparently no accident, with the family of the tomb's
Rare 309-million-year-old fossils suggest early tetrapods developed without tadpole phase
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.
Mini monitor measures artificial heartbeat
An international team, including the University of Tokyo, has created a sensor inspired by the lateral line in fish—their "sixth sense" organ—which measures the pulse of lab-grown 3D heart tissue (cardiac organoids). The device, called a biomechanical well plate, looks like a
Is AI ruining our skills? Early results are in—and they’re not good
Reliance on artificial-intelligence tools degrades the abilities of physicians and software engineers, studies show
Wild yeast discovery enables non-GM brewing of ornithine-enriched craft beer
As consumer interest grows in foods and beverages with added nutritional value, brewers are exploring ways to improve fermentation itself rather than relying on post-production additives. Ornithine, a naturally occurring amino acid involved in several biological processes, has
Spain data on 5.5 million convictions challenges immigration-crime link
When analyzing crime, the foreign population typically shows higher rates than the native population. However, crime statistics change significantly when comparing groups of the same age and gender. A detailed data analysis conducted in a study by the Universidad Carlos III de
Controlling magnetic chirality could help memory pack in more data
Magnetic storage devices, like a computer's hard disk drive, utilize magnets to represent binary data. However, as these devices are downsized, stray magnetic fields generated by individual magnetic components can interact with neighboring elements to cause operational
'Very dangerous' super typhoon nears US Pacific islands
Howling winds and lashing rain battered Guam and the Northern Marianas late Sunday, hours before the projected arrival of a "super typhoon" with force equivalent to a Category 5 hurricane over the U.S. Pacific territories.
Astronomers find biggest super-puff planets yet that are lighter than cotton candy
Astronomers have uncovered a pair of giant planets that are lighter than cotton candy—super-puffs the size of Jupiter.
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.
