The discovery could open the door to advanced glasses with capabilities that were previously difficult…
For most of the 20th century, the model of human origins was a tree: with the trunk dividing into branches, and then twigs. Each species of human relative (hominin) was a neat, single branch. As an undergraduate, I was taught that Homo sapiens was one of these branches that emerged…
You walk out of the grocery store, ready to head home and make dinner. But as you scan the crowded parking lot, a frustrating question comes to mind. Where did you leave your car? You try to picture the spot, but the memory refuses to surface. Remembering personal experiences like…
Scientists have developed a new gel that could make it possible to regrow damaged tooth enamel, potentially overcoming one of the biggest limitations in dental care. Unlike bones and many other tissues in the body, tooth enamel cannot naturally regenerate once it has been lost. The new treatment offers a…
Scientists have solved a biological mystery that remained unanswered for more than three decades, uncovering an unexpected way the immune system protects the body from its own inflammatory response. The breakthrough reveals that a chemical signal responsible for attracting immune cells to fight infections also helps prevent those same defenses…
One of the biggest obstacles in quantum computing is surprisingly simple to describe: how do you read information without changing or destroying it? Unlike the bits used in ordinary computers, quantum bits, or qubits, are extraordinarily sensitive to measurement. Trying to determine their state can cause that state to collapse,…
Viruses are usually associated with causing infections, but some can actually help fight them. Scientists are now working to turn these bacteria-killing viruses into treatments for dangerous infections that no longer respond to conventional antibiotics. An international team of experts has taken an important step toward making this approach safer…
Muscles can begin losing their strength and ability to recover surprisingly early in the aging process. Over time, muscle tissue may develop scar tissue, accumulate fat, and lose some of the specialized fibers responsible for rapid, powerful movements. These changes can make everyday activities more difficult and gradually reduce mobility…
Why does the left side of the brain control the right side of the body, while the right side controls the left? This unusual arrangement is one of the most intriguing features of the nervous system, and scientists have proposed a new explanation that reaches back hundreds of millions of…
Keeping daylight saving time in effect all year could bring brighter evenings, but new research suggests the change would come with a troubling consequence for American children. A nationwide switch could result in at least 2 billion additional trips to school in darkness, potentially increasing safety risks while reducing children’s…
Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered that applying a small amount of pressure can dramatically alter the magnetic properties of a promising new class of materials called altermagnets. Using neutron experiments, the researchers uncovered how a simple mechanical squeeze can change the way these…
Scientists have spent decades trying to control how tiny particles connect to form advanced materials. Now, researchers at MIT and their collaborators have discovered that doing the exact opposite of what was previously believed necessary can produce remarkable results. Instead of relying on rigid molecular connections to hold nanoparticles in…
NASA is investigating whether private space companies could help extend the life of the Hubble Space Telescope, which has spent more than 35 years transforming our understanding of the universe. On October 29, the agency issued a Request for Information seeking details about commercial technologies that could be used to…
For nearly 90 years, physicists have divided magnetic materials into two main categories: ferromagnets and antiferromagnets. Now, scientists have confirmed that a third type exists, revealing a previously unrecognized form of magnetic behavior that could lead to major advances in computing and electronics. The breakthrough comes from a research team…
Scientists at Stanford Medicine have identified a naturally occurring molecule that could lead to a new generation of weight loss medications.
