Engineers have discovered an unexpected link between two very different realms of physics: the behavior of electrons in graphene and magnetic waves in specially engineered materials. By designing a thin magnetic film with a hexagonal pattern of holes—similar to graphene’s
A Yale study found that lowering parent stress can help protect young children from obesity. When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and
A new brain-imaging study has revealed how ketamine produces its fast antidepressant effects in people with treatment-resistant depression. Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ketamine reshapes its activity in
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia University show how quantum properties can be
While exploring ancient seabeds in Morocco, scientists discovered strange wrinkle-like textures in deep-water sediments that shouldn’t have been there. These structures are usually made by sunlight-loving microbial mats in shallow waters. But the rocks formed far below the
Local recreation areas play an important role in reducing stress. In two new publications, researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL show how visual impressions and sounds interact in this process—and how this knowledge can be used
A massive UK study of more than 165,000 dementia patients has uncovered troubling new evidence about risperidone, a commonly used drug for severe agitation. Researchers found the antipsychotic increases stroke risk in dementia patients across the board—including those with no
Roughly 425 million years ago, in the warm seas over what is now southern China, there lived a meter-long bony fish with jaws full of clusters of spiky teeth.
In physics, the mesoscale lies between the microscopic and the macroscopic. It is not just the domain of tiny living creatures like small larvae, shrimp, and jellyfish, but also where physics equations become extreme. While the macroscopic realm is governed by inertia and the
A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol.
Nonsense-mediated mRNA decay (NMD) is one of the most important processes in our cells to ensure that no faulty or incomplete proteins are produced. Scientists have now identified a central mechanism behind this control system.
Evidence suggests that China's "cradle of civilization" experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient inland disasters were unclear. In a new study,
Payments that enable landowners to rewild ecologically degraded land—in the form of biodiversity credits bought by investors wishing to offset their impact on nature—could be an effective component of the emerging market for nature recovery, but will not work as a standalone
The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers have demonstrated that they share a mathematical
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard University showed how extremely weak light signals could
A recent report on global tipping points warned that coral reefs face widespread dieback and have reached a point from which they cannot recover.
The Doomsday Clock—a symbolic device to signal an array of existential threats to the world since 1947—was recently moved to 85 seconds before midnight, the closest it has ever been to midnight. And that was before all-out war broke out in Iran.
At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have done the math to show just how long you might have to wait.
Look up on a clear night and you'll see the streaks of our new space age. What you don't see is the growing fallout for the atmosphere that keeps us alive.
Europe is struggling more and more with extreme heat in the summer. While climate change is the main reason for this increase, what specific physical mechanisms cause a heat wave? One important driver of weather conditions in Europe is the North Atlantic. For example, studies
A thin band of light from Cristian Lucanas's headlamp pierces the blackness of a Philippine rainforest as he digs through the underbrush before gently scooping up a cockroach with his bare hands.
A Purdue University contraceptive vaccine seeks to address animal overpopulation by markedly reducing fertility in feral horses, deer, swine and other animals. Dr. Harm HogenEsch, distinguished professor of immunopathology in Purdue University's College of Veterinary Medicine,
Long-term ecosystem warming changes not only plants but the fungi in the soil below, according to a new study including researchers from the University of Tennessee, Knoxville. "Hidden mycorrhizal fungi below ground are much more vulnerable to warming winters than we expected
The science of the zodiac is more intriguing than astrology would have you think
Losing an hour of sleep to daylight saving time is not good for you, but there are ways you can help yourself bounce back
Fluorescent proteins with a quantum upgrade could offer unprecedented views inside cells
Satellites are giving scientists a powerful new way to watch over the world’s bridges. Using radar imaging, researchers can detect millimeter-scale movements that may signal early structural problems long before inspectors notice them. The study found many bridges—especially in
Consciousness and animal communications experts weigh in on whether the mind-melding science in Hoppers could ever be possible
Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways
Scientists have uncovered a surprising new role for little-known brain cells called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove toxic tau protein from the brain by transporting it from the cerebrospinal
Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of “cool” works at the molecular level—and could inspire new treatments for pain and eye
Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number of protons equals the number of neutrons. For decades, these strange regions—where atomic nuclei abandon their usual orderly structure and become strongly
