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, […]
