Medical Xpress / Cardiorespiratory fitness may cut dementia, depression and psychosis risk
Many studies carried out over the past decades have explored the relationship between mental and physical health, showing that the two are often interlinked. One well-established indicator of overall physical health is cardiorespiratory ...
Phys.org / The edge of the Milky Way's star-forming disk revealed
How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of astronomers has identified the ...
Phys.org / More effective, longer-lasting sunscreen made from natural extracts
Scientists from the Laboratory of Dermatological Photobiology of the University of Malaga, in collaboration with Cantabria Labs España, have carried out a study in which, for the first time, they have demonstrated how a natural ...
Phys.org / Half of America sits in democratic limbo—and that silent middle may decide what breaks next
If you were to ask democracy scholars what they consider the greatest threat to American democracy, you might assume it is voters who support undemocratic practices or policies. But the real answer may surprise you: These ...
Phys.org / Water to surge into drought-depleted Lake Powell but at costs elsewhere
Canyons in eastern Utah will churn this spring with huge volumes of water—as much as 50,000 toilets flushing constantly at the same time—in a desperate attempt to maintain electricity generation for thousands of homes across ...
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Phys.org / Cell membranes may store memories after electrical stimulation
The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, ...
Phys.org / Deep-rooted grass stores significantly more carbon, says new study
Soil biologist Eric Slessarev has some advice for conservationists, landscapers, and farmers with fallow fields: Go touch deep-rooted grass. Or better yet, go plant some. Slessarev, an assistant professor of ecology and evolutionary ...
Phys.org / Crabs' iconic sideways walk evolved from common ancestor, study suggests
Researchers have provided new insights into the evolutionary origin of sideways walking in crabs. Their study, published today as a Reviewed Preprint in eLife, presents the largest comparative dataset on crab locomotion to ...
Phys.org / Assessing the impact of golf courses on water scarcity in the Colorado River Basin
In 2023, University of Delaware doctoral candidate Mehrnaz Haghdadi and doctoral student Nora Lucas headed to the Colorado River Basin to conduct fieldwork for Haghdadi's research focused on indigenous water sovereignty.
Phys.org / Astronomers precisely date rare brown dwarf companion, offering new test for how these objects cool
Astronomers at the University of Hawaiʻi have precisely measured the age of a nearby sun-like star and its unusual companion, known as a brown dwarf, an object that falls between a planet and a star. The discovery offers ...
Medical Xpress / Robust flu protection may rely on B cells that are long-lived residents in the lungs
Deep in the lungs, resident memory B cells stand guard against influenza reinfection—but whether they remain there may depend on how strongly they are signaled through their own receptors. New research using an animal model ...
