An enormous icy world discovered beyond Pluto could soon become the sixth officially recognized dwarf planet in our solar system. The object, temporarily named 2026 ED138, was identified by an astronomer analyzing observations from the Simonyi Survey Telescope at the NSF-DOE Vera C. Rubin Observatory. Early estimates suggest it ranks…
Used coffee grounds may be far more valuable than they appear. Instead of ending up in the trash, this everyday waste could provide ingredients for renewable fuels and a variety of useful chemicals. Researchers at Universitat Rovira i Virgili (URV) have identified an efficient way to recover oil from discarded…
A growing body of research suggests that aging may be more flexible than once believed. Now, scientists at Yale have taken an important step toward identifying which treatments can actually influence biological aging and which ones show little measurable benefit. Their findings suggest that certain prescription medications and lifestyle changes…
New forensic evidence suggests that some of ancient Egypt’s earliest rulers had members of their royal households killed when they died, possibly so those individuals could continue serving them in the afterlife. The discovery sheds new light on a disturbing burial practice that archaeologists suspected more than a century ago…
A smile might brighten your mood, but new research suggests that forcing yourself to smile over and over can have the opposite effect. When smiling becomes an obligation, especially one tied to financial pressure, it may actually leave people feeling less happy and more irritated. For years, psychologist Nicholas Coles,…
Physicists have captured an extraordinary quantum phenomenon in which electrons appear to leap across energy gaps that would normally be off limits. Using a new type of slow-motion electron camera, researchers were able to watch these incredibly fast movements in graphene, revealing how powerful electric fields can drive electrons between…
Simulating the complex behavior of light inside powerful laser systems requires enormous computing resources, making it difficult for researchers to predict and adjust laser performance quickly. Now, scientists at Stanford University, the University of California, Los Angeles (UCLA), and SLAC National Accelerator Laboratory have developed an artificial intelligence model that…
Vaccines may do more than protect people from the immediate effects of a viral infection. New research suggests they could also help prevent lasting damage to the immune system that remains even after the virus has disappeared. Scientists at Pompeu Fabra University discovered that mice recovering from an acute viral…
A major study involving more than 750,000 pregnancies has uncovered an important difference in the potential pregnancy risks of popular weight loss medications such as Ozempic and Wegovy. Women who unintentionally used these drugs shortly before or during early pregnancy were more likely to give birth prematurely, but only when…
A major new study suggests that many adults age 70 and older who have never experienced a heart attack or stroke may be able to stop taking statins without substantially increasing their short-term cardiovascular risks. However, the findings also point to a possible increase in risk over a longer period,…
Why do some volcanoes send towering fountains of lava into the sky while others release molten rock in much calmer eruptions? Scientists have discovered that a hidden effect of extreme heat inside magma may help explain these striking differences. An international research team led by The University of Manchester investigated…
For decades, scientists have generally assumed that dark energy, the mysterious component thought to be responsible for the Universe’s accelerating expansion, has remained constant throughout cosmic history. That long-standing assumption is now facing new scrutiny. Observations from the Dark Energy Spectroscopic Instrument (DESI), which is constructing the largest three-dimensional map…
In May 2024, an extraordinary solar storm sent brilliant auroras across skies in parts of the world where the northern and southern lights are rarely visible. But the spectacular displays were only the most obvious signs of an enormous disturbance unfolding in space around Earth. Deep within the planet’s magnetosphere,…
A new computational technique could accelerate the search for diamond materials capable of powering future quantum computers and highly sensitive sensors. Developed by a researcher at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), the method makes it much easier to identify promising materials for quantum technology,…
When muscles are injured, the body normally activates specialized stem cells that help rebuild damaged tissue. But scientists have discovered that without one critical protein, this repair system can break down, leaving injured muscles filled with fat and scar tissue instead of healthy muscle. Researchers at the Perelman School of…
A promising new approach to building computer chips could dramatically reduce the energy needed for computing, including the rapidly growing demands of artificial intelligence. At the center of the breakthrough is a special class of materials known as multiferroics, which combine electrical and magnetic properties that can be controlled together…
A new study from the University of Eastern Finland has identified an intriguing relationship between the types of protein men consume and their testosterone levels. Researchers found that men who ate more animal protein tended to have lower testosterone concentrations in their blood, while those who consumed more plant protein…
For some children, learning math is much more difficult than it is for their classmates. Even when they practice and receive instruction, they may continue to struggle with problems that other children their age can solve more easily. Researchers are now uncovering clues about why these difficulties persist, and the…
Crows can make visual decisions twice as quickly as humans and monkeys, according to new research from the University of Tübingen. In experiments involving two carrion crows, the birds needed an average of just 235 milliseconds to determine which way a pattern of moving dots was traveling and respond with…
Colorectal cancer rates are climbing again in the United States after more than two decades of decline, and the troubling increase is affecting far more than younger adults. New research published in NEJM Evidence reveals that the disease is becoming more common across nearly every age group under 70, raising…
