Archaeologists in Russia have unearthed a rare wooden tomb containing the remains of an elite man who was buried with a horse and a dog. The remarkably preserved burial, which dates to the 10th century, suggests that medieval Russian and Northern European nobility shared funeral customs a millennium ago. The horseman's burial was discovered unexpectedly this summer during excavations in the medie

In the early hours of July 16, 1945, in a remote part of the New Mexico desert, a group of scientists, engineers and military personnel attended an event that would define the course of history and change a war that had ravaged much of the world for years. Moments after a giant fireball rose high into the sky, a huge shock wave thundered toward the onlooking crowd. The Trinity nuclear test had be

We all know that a dropped or shaken soda can comes with the risk of a fizzy eruption. People use different techniques to prevent these bubbly blasts, including tapping the top of the can. This advice has been passed around for years, but does it actually work? The answer lies in the physics of what's happening inside the can. Building the bubbles To make a carbonated drink, carbon dioxide is inj

Scientists have finally gotten to the bottom of why astronauts struggle to poop in space, thanks to a new blood test. The findings also reveal an unexpected side effect of this cosmic constipation that may need to be addressed before humans take long-haul trips to Mars and beyond, the study authors say. As soon as people started living in space, it became apparent that it was harder to go "number

The dream of coming home to a spotless kitchen you didn't have to clean yourself is edging closer to reality. We're used to seeing robotic vacuums cleaning our floors — but what about all our other chores? Humanoid robots are being engineered to take care of more complex tasks around the house, from folding laundry to loading the dishwasher. This month, San Francisco-based startup Tau Robotics be

Last year, scientists achieved a historic first by providing a patient with the first-ever corneal implant made solely of human cells grown in the lab. Corneal transplants are used to treat severe corneal scarring and inflammation, eye injuries and complications from eye surgeries. They replace the clear dome at the front of the eye, and usually, the tissues for the procedure are collected from o

NASA's Swift Observatory is set to come crashing down to Earth later this year after a private mission failed to save the tumbling telescope. A rescue spacecraft named LINK, which was designed by private company Katalyst Space, launched on July 3 with the aim of raising the falling observatory to a higher orbit. However, in the weeks following launch, the rescue mission itself encountered problem

In 2010, researchers at Purdue University and the University of New South Wales began an investigation into a macabre question: What's the upper temperature limit at which humans can survive? The answer, according to their calculations, was 95 degrees Fahrenheit (35 degrees Celsius) at 100% humidity — a "wet bulb" temperature that sets an absolute "unsurvivable" threshold for the human body.

Astronomers have found the most promising candidate yet for a "black hole star," a new type of astrophysical object lurking in the early universe's "cosmic dawn." If confirmed, the findings could help to unravel the mysterious origin of " little red dots " (LRDs), an infamous group of hundreds of distant, crimson lights spotted by the James Webb Space Telescope (JWST). These dots, which are almos

A cave in eastern Spain is revealing new clues about the ritual lives of Roman women, after archaeologists documented more than 120 Latin inscriptions — the highest number known anywhere in the Roman Empire — at an underground sanctuary. Five of the inscriptions mention a previously unknown goddess referred to simply as "the Lady." Researchers unearthed the inscriptions during a 2026 excavation a

Researchers have pioneered a way to create miniaturized copies of a person's carotid artery that could help doctors predict and manage the patient's stroke risk, a new study suggests. In the research, published in July in the journal Cell Biomaterials , scientists used these "arteries-on-a-chip" to monitor how real blood flows through a patient's carotid arteries, which carry blood to the brain,

Archaeologists have discovered a possible human sacrifice near the pyramid of Huaca Pucllana in the center of Lima, Peru. The skeleton may represent an offering connected to a ceremonial well that was closed up nearly 1,400 years ago. Bones of an adult male were excavated from an underground water channel at the archaeological site earlier this year, according to an Aug. 18 translated statement f
Cats can identify each other based on the scent of their pee, and researchers have just decoded the secret "messages" that make that possible. A group of chemicals called branched-chain fatty acids (BFAs) help give cats their unique scent marks, a new study found. Unusual fat droplets in the cats' kidneys likely help them maintain that chemical fingerprint in each mark. The researchers reported t

IBM has revealed a new modular, ultracold system designed to link hundreds of quantum computer chips together to solve one of the field's biggest infrastructure bottlenecks. The company says its new "quantum fridges" will let it deliver the world's first fault-tolerant quantum computer in 2029. These stable systems use quantum error correction techniques to fix noise in real time and run quantum

Concerns are on the rise about young people's social media use as governments, parents and schools look to curb children's exposure to threats such as cyberbullying and sexual harassment . Other experts are worried about the rise in misinformation, including misleading medical and health content or the oversimplification of conditions like ADHD . One proposed solution is to ban children below a c
The brain develops in stages, and it's important that certain cells form before others so that precise neural connections can emerge later. But miniature models of the brain, called organoids, may not share this same sense of time, a new study finds. These brain organoids are clusters of lab-grown neurons that mimic structural and functional aspects of full-size brains. Some scientists use these
Astronomers have discovered the closest, fastest star ever seen orbiting Sagittarius A* (Sgr A*), the 4.3 million-solar-mass black hole at the heart of our galaxy. The faint star, named S301, completes a lap every 8.7 years and skims past the black hole at roughly 55 million mph (90 million km/h) — about 8% the speed of light. Its orbit is so tight that, within about a decade, researchers should
NASA has finally revealed its first images of the crater made by a SpaceX Falcon 9 upper stage that smashed into the moon on Aug. 5. The images, captured by the space agency's Lunar Reconnaissance Orbiter (LRO) between Aug. 11 and 12, show a 60-foot-wide (18 meters) crater surrounded by streaks of lunar rock thrown up by the rocket's impact. The new crater was carved into the lunar surface by the

Over the past decade, there's been a revolution in archaeology as we integrate the science of ancient genomics into the study of humanity — and it is upending our traditional views of the role of women in the past. When archaeologists first excavated a 4,000-year-old grave near Stonehenge in 1801, they identified the well-furnished remains inside as that of a man. This misidentification persist

Neanderthals may have trekked deep into the deserts of the Arabian Peninsula around 55,000 years ago, a new study of stone tools suggests. The research, published online Aug. 12 in the journal Quaternary Science Reviews , hints that Neanderthals may have lived farther south than scientists thought, though more evidence is needed to confirm that conclusion.

Scientists have successfully shrunk three components used in photonic microchips by up to 500 times, leaving considerably more space for other on-chip functionality. The achievement was made possible with an artificial intelligence (AI) algorithm that generated these tiny designs, which the researchers described as "beyond human intuition." Whereas conventional microchips use electrons to transmi
