Phys.org / Young 'sun' caught blowing bubbles by Chandra
For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere"—completely surrounds ...
Phys.org / Source or sink? Trees with heart rot disease emit more methane, upending forest carbon models
Throughout their lifetimes, healthy forests produce more oxygen than they use, while taking in greenhouse gases via plants and soils. This ecosystem-wide service, called carbon sequestration, regulates global climate and ...
Medical Xpress / Meningococcal B vaccination does not reduce gonorrhea, trial results show
Contrary to existing evidence from observational studies, the meningococcal B vaccine (4CMenB) has no effect on preventing the acquisition of gonorrhea, according to the results of the world's largest randomized control trial ...
Phys.org / NASA moves its Artemis II moon rocket off the launch pad for more repairs
NASA moved its grounded Artemis moon rocket from the launch pad back to its hangar Wednesday for more repairs.
Medical Xpress / Novel markers of brain blood flow and oxygenation may offer early clues to Alzheimer's risk
Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics ...
Phys.org / Too much transparency can hurt financial markets
These days, transparency is a financial buzzword. Opening the curtains on the operations of financial markets is supposed to help investors and regulators make better decisions. But sometimes transparency can backfire, according ...
Medical Xpress / Medicare Advantage and Medicare–Medicaid eligible patients less likely to use highly rated stroke rehabilitation
Stroke patients with Medicare Advantage health insurance plans are less likely to be discharged to highly rated post-acute care than those covered by traditional Medicare, according to a new study co-led by researchers at ...
Phys.org / AI provides a more precise time of death post-mortem
Artificial intelligence can be used to provide a more precise time of death, which could be crucial in murder investigations. The method was developed by researchers at Linköping University and the Swedish National Board ...
Phys.org / Living tissues are shaped by self-propelled topological defects, biophysicists find
With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical ...
Phys.org / Symbiotic bacteria in planthoppers break record for smallest non-organelle genome ever found
Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of these symbiotic bacteria ...
Medical Xpress / Did you hear about the lab-made ear?
In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.
Phys.org / New study reveals what crop advisors really want from AI tools
A new study co-authored by Virginia Tech and University of Vermont researchers offers one of the first, large-scale empirical looks at how Certified Crop Advisors (CCAs) across North America evaluate the next generation of ...
