Light amplification accelerates chemical reactions in aerosols
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid droplets and very fine particles can trap light — similar to […]
Owners Can Play Big Role in Dogs’ Problem Behaviors
Latest Pet Health News Dennis Thompson MONDAY, March 28, 2022 (HealthDay News) Chasing light shimmers reflected onto a wall. Obsessive licking or chewing. Compulsive barking and whining. Pacing or tail chasing. Nearly one in three pet dogs suffer from these ADHD-like repetitive behaviors — and researchers now suspect that an animal’s home life could be […]
Large study challenges the theory that light alcohol consumption benefits heart health: Any observed benefit likely results from other lifestyle factors common among light to moderate drinkers, say researchers
Observational research has suggested that light alcohol consumption may provide heart-related health benefits, but in a large study published in JAMA Network Open, alcohol intake at all levels was linked with higher risks of cardiovascular disease. The findings, which are published by a team led by researchers at Massachusetts General Hospital (MGH) and the Broad […]
Brain Volumes Shrink With One Daily Drink
Light to moderate alcohol consumption — as few as one or two drinks a day — was linked with reductions in overall brain volume, a cross-sectional study showed. Among nearly 37,000 healthy adults in the U.K. Biobank, alcohol intake was negatively associated with global brain volume measures, regional gray matter volumes, and white matter microstructure, […]
Hubble finds a black hole igniting star formation in a dwarf galaxy
Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA’s Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm […]
Exquisitely preserved embryo found inside fossilized dinosaur egg
A 72 to 66-million-year-old embryo found inside a fossilised dinosaur egg sheds new light on the link between the behaviour of modern birds and dinosaurs, according to a new study. The embryo, dubbed ‘Baby Yingliang’, was discovered in the Late Cretaceous rocks of Ganzhou, southern China and belongs to a toothless theropod dinosaur, or oviraptorosaur. […]
Atom laser creates reflective patterns similar to light
Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass. In experiments at Washington State University, scientists have developed a technique […]
Morning exposure to deep red light improves declining eyesight
Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study by UCL researchers. Published in Scientific Reports, the study builds on the team’s previous work*, which showed daily three-minute exposure to longwave deep red light ‘switched on’ energy […]
Microbiology research furthers understanding of ocean’s role in carbon cycling
Microbiology researchers at Oregon State University have shed new light on the mechanisms of carbon cycling in the ocean, using a novel approach to track which microbes are consuming different types of organic carbon produced by common phytoplankton species. The research is an important step toward forecasting how much carbon will leave the ocean for […]
Astronomers may have discovered first planet to orbit 3 stars: Potential discovery of a circumtriple planet has implications for bolstering our understanding of planet formation
In a distant star system — a mere 1,300 light years away from Earth — UNLV researchers and colleagues may have identified the first known planet to orbit three stars. Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed […]
