Scientists have developed a low-cost device that can continuously check air ducts at nuclear facilities for traces of radioactive material. The detector, created at the U.S. Department of Energy’s Oak Ridge National Laboratory, or ORNL, can take measurements once a minute when running on a battery. When connected through an Ethernet cable, it can collect […]

Scientists have discovered that the weather on a distant world may be far more organized than it first appears. The object, known as SIMP 0136, is a brown dwarf located about 20 light-years from Earth. It is larger and hotter than a gas giant planet such as Jupiter, but it is not massive enough to […]

Networks shape much of the world around us. Friendships form social networks, computers connect through the internet, brain regions communicate with one another, and countries are linked through trade. However, scientists often face two major difficulties when studying these systems. They may see only part of a network, and they must decide whether an apparent […]

Scientists have developed a new way to make an extremely strong metal-based material much less likely to break when it is bent or squeezed. The discovery could eventually lead to tougher materials for aircraft engines, turbines, energy systems and other machines that operate under extreme conditions. The research was led by engineers at Purdue University […]

Quantum computers promise to solve some problems that are extremely difficult for today’s computers. But there is a major obstacle: quantum information is very fragile, and even tiny disturbances can cause a calculation to go wrong. Researchers at Chalmers University of Technology in Sweden have now proposed a way to perform a wide range of […]

A tiny crocodile relative that lived about 125 million years ago has given scientists an unusually detailed look at what ancient reptiles may have looked like. A remarkably preserved fossil from northeastern Spain contains traces of skin, soft body parts and even a possible pattern of light and dark bands on its tail. The animal, […]

Social media began as a simple way to keep in touch with friends and family. Today, many people can spend hours moving through an almost endless stream of videos, photographs, opinions and recommendations from people they have never met. A major new analysis suggests this change may have consequences for mental health. Researchers found that […]

A night’s sleep may seem like a quiet break from the day, but the brain remains busy. While we sleep, it sorts through new information, strengthens some memories and prepares us to learn again when we wake up. That nighttime work becomes especially important as people get older. Many older adults notice that the small […]

Semaglutide is best known as the active ingredient in the diabetes drug Ozempic and the weight-loss drug Wegovy. It belongs to a group of medicines called GLP-1 drugs, which can reduce appetite, improve blood sugar control and help people lose weight. New animal research suggests the drug may also affect some of the biological changes […]

Scientists searching for ways to protect the aging brain have turned to an unusual source: sea squirts. A study in aged mice found that supplements rich in plasmalogens, molecules found in these marine animals and in the human body, were linked with better learning, healthier brain connections and lower brain inflammation. The findings sound dramatic, […]

For years, many women have faced a confusing message about menopause hormone therapy. It can be extremely effective for hot flashes and night sweats, yet older research created fears that the same treatment might harm the heart. A new U.S. study offers a more detailed picture. Researchers found that women with menopause symptoms who started […]

For decades, one of the biggest problems in pain medicine has been surprisingly simple: the strongest medicines often come with the greatest risks. Opioids can make severe pain manageable, but they can also cause dependence, addiction, overdose and troublesome side effects. A new drug called LTG-001 is being developed to see whether powerful pain relief […]

Losing weight is one challenge, but keeping it off while maintaining a healthy diet can be even harder. New research suggests that a Mediterranean-inspired eating plan redesigned for the American South can help adults maintain weight loss for two years while improving the nutritional quality of their diets. The program is called Med-South and was […]

A person being treated for heart disease may also have a hidden problem in the kidneys. New European guidelines say doctors should look for that connection much earlier, because damage to the heart and kidneys can feed into each other and increase the risk of serious illness. The European Society of Cardiology developed the new […]

Fatty liver disease is extremely common, and many people have it without knowing. For years, it was often treated as a problem mainly involving the liver, especially when patients had no obvious symptoms. A new scientific review argues that this view may be too narrow. Researchers led by the University of Manchester and Northern Care […]

Diabetes can slowly damage nerves throughout the body, leaving some people with pain, burning, tingling, or numbness that can become difficult to manage. Now, scientists at UTHealth Houston have developed an experimental treatment that slowed and even reversed this type of nerve damage in mice. The research was published in Science Translational Medicine. Although the […]

A mammogram does more than search for suspicious lumps. It can also show whether a woman’s breasts contain a large amount of dense tissue, a feature that has long been associated with a higher chance of developing breast cancer. For many years, breast density was especially important because it could hide small tumors on mammograms. […]

Air pollution is often discussed as a long-term health threat, but new research suggests the body may begin responding after only a few hours. Scientists at the University of Louisville found that about three hours of exposure to polluted air was linked to a small but measurable change in the way the nervous system controls […]

Living with type 1 diabetes means making decisions about blood sugar every day. Even when people carefully count carbohydrates, use insulin correctly, and check their glucose regularly, their levels can still rise or fall unexpectedly. Researchers at Kaunas University of Technology, or KTU, are testing whether artificial intelligence could make these changes easier to anticipate. […]

A study has found a possible link between vitamin B12 and inflammation in the body. People with higher levels of vitamin B12 in their blood tended to have lower levels of two important signs of inflammation. The research was published in the Journal of the Science of Food and Agriculture. The findings add to growing […]
