A large international study suggests today’s hip replacements may last much longer than previously thought. Hip replacement surgery has become so successful that more people are receiving new hips at younger ages than ever before. That success has also raised an important question: can today’s artificial joints keep pace with decades of active living? A [...]

A swallowed fish bone can be far more dangerous than a brief choking scare. For Shirley Ballas, a meal turned frightening when a fish bone stuck in her throat and left her struggling to breathe. The Strictly Come Dancing judge later said she’d “thought that was it” during the 20-minute ordeal, before her hair and [...]

A modest daily glass of orange juice may influence inflammation, blood flow, and other markers tied to long-term heart health. Orange juice is often treated as a familiar breakfast drink, not something that might alter what is happening inside immune cells. But emerging research suggests that regular intake may influence biological pathways tied to inflammation, [...]

The magnets powering electric cars and wind turbines come with a hidden environmental cost. Swedish researchers are working on a cleaner alternative. The global transition to clean energy depends on a handful of materials that most people never see. Rare earth magnets power everything from electric vehicles and offshore wind turbines to smartphones and advanced [...]

New observations show that the supermassive black hole at the center of the Milky Way does not consume nearby dust objects as previously thought. Near the heart of the Milky Way, where the supermassive black hole Sagittarius A* bends nearby space with immense gravity, astronomers have been watching several strange dusty objects for signs of [...]

A black hole shredded a massive star in a record-breaking explosion, but what astronomers discovered afterward may be even more remarkable. Black holes are among the most destructive objects in the universe, but astronomers have now witnessed one carrying out an act of cosmic violence unlike anything seen before. A newly discovered event appears to [...]

Scientists discovered that building a healthy brain involves an unexpected step: young neurons routinely break and rapidly repair their own DNA. As the brain develops, newly formed nerve cells must travel through tightly packed tissue to reach the locations where they will become part of the brain’s neural networks. That demanding journey turns out to [...]

Experts say the future of obesity treatment will extend far beyond GLP-1 drugs by combining medications with personalized therapies and advanced procedures. The arrival of GLP-1 medications such as semaglutide (Wegovy, Ozempic, Rybelsus) and tirzepatide (Mounjaro, Zepbound) has dramatically changed how obesity is treated. But while these drugs have produced impressive results, experts say they [...]

Researchers have developed a way to grow and genetically engineer progenitor cells that produce macrophages, first responder immune cells with potential for new immunotherapies against cancer and other diseases. Macrophages look almost built for the hardest parts of cancer therapy. They can push into tumors, swallow dangerous cells, and help alert the wider immune system. [...]

A simple twist of ultra-thin material gave scientists surprising control over quantum light, bringing future quantum technologies closer to reality. University of Technology Sydney researchers have discovered a new way to control tiny quantum light sources by twisting ultra-thin layers of hexagonal boron nitride, a breakthrough that could help move quantum technologies closer to real-world [...]

Powerful winds from supermassive black holes may explain why some of the universe’s largest galaxies stopped making as many stars as expected. Astronomers are gaining new insight into one of the universe’s biggest puzzles thanks to the X-Ray Imaging and Spectroscopy Mission (XRISM). Researchers at the University of Michigan have uncovered evidence that powerful winds [...]

A new plasma chemistry breakthrough could help manufacturers build the next generation of smaller, faster, and more powerful computer chips. Modern computer chips contain billions of silicon transistors, but silicon is nearing the limits of how small and powerful it can become. To keep improving electronics, scientists are investigating ultrathin materials that could work alongside [...]

Ebola and hantavirus can look like the flu at first, making early detection and rapid infection control essential to saving lives. Two dangerous viral diseases, Ebola and hantavirus, have drawn renewed attention in recent weeks because of their potential to cause severe illness and their importance to public health. Although they are very different diseases, [...]

By studying long-lived families, scientists have uncovered a rare genetic clue that may help explain why some people stay healthier and live longer than others. Scientists are uncovering new clues about why some people remain healthy well into old age while others develop chronic illnesses much earlier. A new study suggests that looking at families [...]

Scientists have developed an experimental molecule that helps the brain’s immune cells fight Alzheimer’s again, reducing toxic plaques and improving memory in animal studies. Scientists have identified an experimental molecule that appears to restore some of the brain’s natural defenses against Alzheimer’s disease by helping immune cells once again contain the toxic protein deposits linked [...]

Scientists have engineered a never-before-seen quantum state, uncovering a new phase of matter with hidden order beyond conventional theory. Researchers have shown that an unusual quantum state known as a “fractional Fermi sea” can be deliberately created, opening the door to a previously unknown phase of matter. The work, published in Physical Review Letters, was [...]

Scientists solved a long-standing mystery by showing that pressure, not tiny spaces alone, determines how water behaves at the nanoscale. Water is one of the most thoroughly studied substances on Earth, yet scientists have spent decades debating a surprisingly simple question: What happens to water’s chemistry when it is squeezed into spaces only a few [...]

Scientists have taken a fresh look at the Milky Way’s mysterious gamma-ray glow using machine learning and uncovered evidence that reshapes a long-running debate. Scientists have taken a fresh look at one of astronomy’s most enduring mysteries, and dark matter is still in the running. An international team led by researchers at the University of [...]

A supplement best known for boosting athletic performance may also have potential as a depression treatment. Creatine has long been associated with strength training and muscle growth, making it one of the most popular and extensively researched sports supplements available. But muscles are not the only tissues that depend on creatine for energy. The brain [...]

A new Oxford calculator predicts an individual’s risk of serious statin-related muscle disorders, helping patients make more personalized treatment decisions. Researchers at the University of Oxford have developed a calculator that estimates a person’s individual risk of developing serious muscle disorders from statins, offering a more personalized way to weigh the benefits and risks of [...]
