A surprising discovery on a small island in the Baltic Sea is changing how scientists think about the relationship between ancient humans and wolves. Researchers have identified wolf remains dating back roughly 3,000 to 5,000 years on the Swedish island of Stora Karlsö. The finding is remarkable because the island…
Researchers have uncovered a hidden feature beneath the Pacific Ocean that helps explain why Japan’s devastating 2011 earthquake and tsunami became so destructive. The discovery also offers new clues that could improve forecasts of future megaquakes and tsunamis. A new study found that a thin layer of soft, clay-rich sediment…
Around 20,000 years ago, a cave was home to generations of owls that regularly coughed up pellets containing the bones of their prey. Those discarded bones later became an unexpected resource for another group of animals. According to a new study published in Royal Society Open Science, ancient bees used…
For much of the early 20th century, quantum mechanics was one of the most puzzling ideas in science. The theory challenged conventional thinking and left even leading physicists struggling to make sense of its implications. A century later, it has become the foundation of technologies that influence daily life, including…
A good night’s sleep does far more than leave you feeling refreshed. It also triggers the release of growth hormone, a key hormone that helps build muscle and bone, burn fat, and support healthy growth. That’s why athletes value quality sleep for recovery, and why teenagers need enough sleep to…
A brilliant field of red, white, and blue stars sparkles across a new image from NASA’s Hubble Space Telescope, resembling a sparkler glowing against the night sky. NASA released the image to commemorate the 250th anniversary of the United States, celebrating the nation’s long history of exploration while showcasing one…

The breathtaking view, shared in celebration of the United States’ 250th anniversary, highlights Messier 3 (M3), one of the largest and most impressive globular clusters in the…
For decades, physicists have wrestled with one of the deepest puzzles in modern science: the “black hole information paradox.” Now, a new theoretical study suggests a possible solution, one that could also shed light on another major mystery in physics, the origin of the mass of fundamental particles. The paradox…
People who live to age 100 and beyond often owe their exceptional longevity to a mix of protective genes and healthy habits. Researchers estimate that genetics account for as much as 50% of the ability to reach extreme old age, while lifestyle factors such as eating a plant forward diet,…
Researchers at UCLA have identified a hidden weakness in some of the most aggressive and difficult-to-treat cancers, raising hopes for a new way to attack tumors that have resisted treatment for decades. Small cell neuroendocrine cancers can develop in the lung, prostate, and ovary. These fast-growing tumors tend to spread…
To mark the 250th anniversary of the United States, NASA has released four spectacular images of deep space from its Chandra X-ray Observatory, each presented in patriotic shades of red, white, and blue. Alongside the images, the agency also unveiled three new sonifications, which transform astronomical observations into sound, offering…
Physicists have developed a new way to control the rotation of molecules inside tiny droplets of liquid helium, marking an important advance in the study of superfluids. By using a specially designed optical centrifuge, the team was able to precisely spin molecules suspended in liquid helium nano-droplets, giving scientists a…
Fireworks may dazzle crowds with brilliant colors and loud explosions, but new research suggests their effects continue long after the show ends. Three recent studies published in American Chemical Society (ACS) journals examined what fireworks leave behind, from discarded debris and airborne particles to chemical compounds released into the atmosphere.…
Recent research from the University of Massachusetts Amherst suggests that using alcohol to cope with stress in early adulthood may have lasting effects on the brain that do not disappear with years of sobriety. The study found that these changes can begin to surface by middle age, reducing mental flexibility,…
Some people remain mentally sharp even though their brains contain the biological changes associated with Alzheimer’s disease. A new study from the Netherlands Institute for Neuroscience suggests that the answer may lie in how a rare group of brain cells, called immature neurons, responds to damage. The findings offer new…
As carbon dioxide (CO2) emissions continue to climb, interest in geoengineering is growing as governments, researchers, and environmental advocates search for ways to limit the worst effects of climate change. These large scale climate interventions could influence rainfall, agriculture, and ecosystems around the world, making their potential benefits and risks…
Scientists have developed a new way to control quantum systems that can make their behavior appear more consistent with time moving backward rather than forward. The research, published in Physical Review X, introduces quantum control protocols that reshape a system’s “arrow of time,” the concept that time naturally moves in…
Scientists have uncovered evidence that could change how doctors think about a common form of stroke and why standard preventive treatments often fail.
