Medical Xpress / Clarifying the interplay between host and gut microbiota in selenium metabolism
Selenium (Se) is an essential trace mineral found in everyday dietary items, such as seafood, meat, and whole grains. Our bodies depend on it for many biological functions, from the synthesis of antioxidant enzymes to immune ...
Science X / A calmer, happier you? One everyday escape may hold the key
A walk through a park may do more than clear your head—it could measurably improve your mental health. In one of the largest reviews of its kind, researchers analyzed nearly 4,000 studies involving more than 10 million people ...
Phys.org / Astronauts briefly take shelter during repair to fix leak on the International Space Station
NASA on Friday temporarily ordered astronauts to take shelter during repairs to fix a fresh leak aboard the International Space Station.
Phys.org / Texas governor wants to speed up work on a fly-breeding factory to fight a cattle parasite
Texas Gov. Greg Abbott expressed concern Friday that a new factory isn't expected to start breeding sterile New World screwworm flies for more than a year as a big part of the effort to stop its flesh-eating larvae from threatening ...
Phys.org / Deep-Earth seismic anomalies may be explained by newly discovered manganese compound
Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, the exact forms of manganese, their abundance and the mechanisms behind these cycles that occur ...
Phys.org / Bumble bees show spontaneous problem-solving, challenging big-brain assumptions
In a new study, bumble bees solve a completely novel object-manipulation task. What makes this behavior especially remarkable is that the bees had never been trained. The findings challenge the long-standing assumption that ...
Phys.org / Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study ...
Phys.org / Measuring gravitational waves in a humming universe with a coordinate-free approach
Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in astronomy. Today, we have a thorough understanding of signals that travel far from their sources through ...
Phys.org / Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV
An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, ...
Phys.org / Britain's oldest cave art may have been rediscovered in Bacon Hole cave
The oldest cave art in Britain may have been discovered, or more likely rediscovered, in a cave on the Gower Peninsula in South Wales, possibly dating back around 17,000 years.
Phys.org / Ultrathin nanotubes reach 1 nanometer, opening path to smaller electronics
Researchers in Japan have created some of the world's smallest semiconducting nanotubes, structures 100,000 times thinner than a human hair. By growing molybdenum disulfide inside protective tubes of boron nitride, the researchers, ...
Medical Xpress / Maternal RSV vaccine cuts infant hospitalizations by 70%, study shows
A study led by researchers at the University of Pittsburgh and UPMC published in JAMA Network Open, found that vaccination against respiratory syncytial virus (RSV) during pregnancy reduced the risk of hospitalization in ...
