Popular GLP-1 medications used for weight loss and type 2 diabetes (such as Ozempic, Wegovy, Mounjaro, Zepbound, Victoza, and Trulicity) have been linked to an unexpected problem involving fingernails. A multinational study found that people taking these drugs were more than four times as likely to report nail detachment, a…
Scientists have uncovered a previously unknown cleanup system at the back of the eye, revealing a hidden route that allows fluid and waste to escape into the body’s lymphatic system. The discovery challenges long-standing assumptions about how the eye functions and could eventually lead to new approaches for treating serious…
The order in which you eat different foods may have a surprising effect on blood sugar levels. Research in mice suggests that consuming fat before carbohydrates can reduce the sharp rise in blood sugar that typically follows a meal. The findings also reveal how hormones and nerve signals work together…
Scientists have reached a major milestone in the quest to build an entirely new kind of clock. After decades of research, a team in Vienna has developed the world’s first self-stabilizing nuclear clock, a device that could eventually measure time with far greater precision than today’s most advanced atomic clocks.…
Microplastics have spread into nearly every corner of the environment. These tiny plastic particles have been found in ocean water, drinking water, and even inside the human body. Although their presence is well documented, scientists are still working to understand what prolonged exposure could mean for human health. Researchers at…
Neanderthals may have used a sticky substance made from tree bark not only to construct tools but also to treat wounds and fight bacterial infections. Scientists have discovered that birch tar, a material commonly associated with prehistoric toolmaking, has antibacterial properties that could have made it useful as an ancient…
A miniature medical device small enough to be delivered through a standard needle could change how doctors treat chronic pain and movement disorders. Developed by scientists at NYU Abu Dhabi in partnership with Cleveland Clinic Abu Dhabi, the technology can regulate nerve activity without surgical implantation, batteries, or connecting wires.…
What if easing knee arthritis pain did not require another pill, an injection, or surgery, but simply changing how you walk? A clinical trial published in The Lancet Rheumatology suggests that a small, carefully chosen adjustment to the angle of your feet could make a meaningful difference. After one year,…
Scientists at the U.S.Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have identified a potentially much more efficient way to achieve fusion ignition, a major milestone in the pursuit of practical fusion energy. Their calculations suggest that changing the order in which plasma is heated and compressed could dramatically…
Loneliness and social isolation are widespread in the United States. According to a 2023 report, about half of U.S. adults experience loneliness, while nearly as many are socially isolated. Despite health consequences that can rival other major risk factors, both problems remain relatively overlooked as urgent public health concerns. Until…
Astronomers have discovered an unusual star system about 300 light-years from Earth where a small star is gradually consuming a nearby brown dwarf. Instead of swallowing its companion in one dramatic event, the star is steadily pulling material from it, creating a cosmic feeding process that could continue for billions…
Patients with a particular form of bowel cancer remained free of recurrence for almost three years after receiving a short course of immunotherapy before surgery, according to new findings from the NEOPRISM-CRC clinical trial led by researchers at UCL and UCLH. The results, which are due to be presented at…
Chronic diabetic ulcers are among the most difficult complications facing modern healthcare. More than 131 million people worldwide are affected, and the wounds are associated with roughly $755 billion in healthcare costs each year. They also carry serious risks, including amputation and death, making it increasingly important to understand why…
Scientists at Caltech and Yale University have developed a way to precisely calculate the Kondo effect in specific real materials, something that had not previously been possible. For decades, researchers have largely depended on simplified models that capture the phenomenon only approximately. The new approach instead works directly from a…
Two people diagnosed with depression can experience vastly different symptoms. One might struggle with persistent anxiety and repetitive negative thoughts, while another may experience trauma related symptoms or substance abuse. But do these differences also appear in the way their brains function? Researchers at the University of Helsinki investigated this…
Scientists have demonstrated a new type of radio antenna that looks remarkably like a lightsaber. Instead of using a conventional metal structure, the device relies on a laser to create a narrow beam of plasma capable of transmitting radio waves. The technology could eventually make it possible to build antennas…
Astronomers revisiting decades-old observations from NASA’s Hubble Space Telescope have found a new clue in a long-running cold case. According to a study published Oct. 5 in Nature Astronomy, an unusual chemical signature suggests that the white dwarf HS 0209+0832 could be home to a second-generation planet. A white dwarf…
Losing body fat is one thing. Losing fat while keeping the muscle that helps you stay strong and active is another, especially as you get older. Research suggests that one particular type of exercise may have an advantage when it comes to achieving both goals. High-intensity interval training (HIIT), which…
Researchers have uncovered previously unknown materials by closely following what happens as molecular precursors break apart and transform during heating. Among the discoveries is a new form of a well-studied clean energy material. The research, published in Nature Communications, focuses on intermediate phases that appear while molecules are being converted…
Scientists searching for new ways to treat bacterial infections are increasingly turning to viruses known as bacteriophages (phages). These viruses specifically target bacteria, allowing them to kill harmful microbes without damaging human cells. They can also attack bacteria that have developed resistance to antibiotics. Phage therapy, however, faces a major…
For the first time, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has demonstrated that it can detect the extremely faint radio glow of hydrogen gas from the distant universe using only its own observations. The result could give scientists a faster and less costly way to investigate dark energy, the…
Nearly a century after Nobel laureate Hans Bethe predicted their existence, scientists have created and observed unusual quantum structures known as “Bethe strings” using ultracold atoms. The experiment, led by quantum physicist Hanns-Christoph Nägerl, provides researchers with a highly controllable way to explore these unusual quantum many-body states. In 1931,…
After spending more than seven months aboard the International Space Station, NASA’s SpaceX Crew-12 astronauts have safely returned to Earth. Their spacecraft splashed down Thursday in the Pacific Ocean near Los Angeles, bringing an extraordinary mission to a close. The four astronauts spent 237 days in orbit, traveled more than…
October is bringing a spectacular lineup of celestial events, including a disappearing planet, two meteor showers, and a bright full Moon just in time for Halloween. As autumn days grow shorter and darkness arrives earlier, the night sky offers more opportunities to witness some remarkable astronomical sights. NASA has highlighted…
An updated Cochrane review has found that nicotine e-cigarettes may help more people stop smoking than several commonly used approaches, including nicotine gum, nicotine patches, behavioral support, or trying to quit without assistance. Smoking remains the world’s leading cause of preventable disease and death. According to the World Health Organization…
Curcumin, berberine, and several other plant-derived substances have drawn attention from scientists because of their potential anti-inflammatory and anticancer effects. New research from Wroclaw Medical University and the University of Wroclaw suggests, however, that these compounds can behave very differently. A substance that appears powerful against cancer cells may not…
For millions of people with osteoarthritis, pain and stiffness can make everyday activities increasingly difficult. Common treatments, including over-the-counter medications and steroid injections, may reduce symptoms for a time, but they do not prevent the underlying joint damage from progressing. New research from Yale suggests a different approach. In a…
A routine experiment involving a microscopic organism from a freshwater pond led scientists to an extraordinary genetic discovery. The tiny creature was found to interpret DNA instructions in a way researchers had never documented before, challenging a long held assumption about how the genetic code works. The surprise came when…
Scientists surveying underwater mountains off Costa Rica have identified a remarkable new coral that is unlike any known coral family.
