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 ...
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 / Black bears are emerging as roaming reservoirs of antibiotic-resistant bacteria across expanding US ranges
A new gut microbiome study of bears in eastern North Carolina expands our understanding of microbial ecosystems in omnivores and contributes to the broader idea that bear feces could help scientists monitor changes in the ...
Phys.org / Photonic chip generates milliwatt-level UV light, 100 times brighter than before
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique ...
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 ...
Tech Xplore / Cheaper, longer-lasting batteries are closer thanks to a pinch of sodium and a supercomputer
The Expanse supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California School of Computing, Information and Data Sciences has played an important role in helping researchers design the next ...
Phys.org / Your phone's next speed boost may come from a strange magnetic jump that rewrites how chips handle heat
A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing ...
Phys.org / What Bronze Age people ate and drank: South Caucasus pottery reveals a surprisingly diverse menu
What culinary practices prevailed in the South Caucasus during the Bronze Age? A new study shows that the cuisine was remarkably diverse. The evidence highlights a multi-ingredient cuisine alongside the central role of dairy ...
Medical Xpress / One hidden factor in your 20s can leave a lasting mark on your heart decades later
Individuals exposed to adverse neighborhood social factors in early adulthood demonstrated a higher risk of developing coronary artery calcification in midlife, a key measure of early cardiovascular disease, according to ...
Tech Xplore / 'Liquid droplet mops' clean solar panels with 99.9% efficiency, cutting water use by 80%
With the rapid expansion of the global solar energy industry, the number of solar panels has surged in recent years. However, pollutants accumulating on panel surfaces can significantly reduce energy conversion efficiency ...
Phys.org / New research reveals cell proteins that drive severe viral infections
Researchers at Umeå University have identified two human cell proteins, NUP98 and NUP153, that play a crucial role in how viruses such as tick-borne encephalitis virus (TBEV), West Nile virus, and dengue virus replicate in ...
Tech Xplore / Tiny 'light-concentrating' particles boost terahertz technology, study shows
Scientists have found a way to boost terahertz technology using particles thousands of times smaller than a grain of sand. Research published in Scientific Reports by Loughborough University's Emergent Photonics Research ...
