Phys.org / When fluctuations shape biodiversity: A minimalist model explains why 'rarity' is so common
An ecosystem is not a still life. Even where everything looks stable—a woodland, a lake, the soil—the internal "bookkeeping" keeps changing: how many individuals belong to which species, and for how long. Some populations ...
Tech Xplore / Study finds 'dosed' nonlinearity can beat linear and fully nonlinear AI
Umbrella or sun cap? Buy or sell stocks? When it comes to questions like these, many people today rely on AI-supported recommendations. Chatbots such as ChatGPT, AI-driven weather forecasts, and financial market predictions ...
Phys.org / When electronics become flexible: Atom-thin materials for future devices
In a paper published in the journal Small, a team of physicists from IISER Pune have developed tiny electronic devices from a special semiconductor material called bismuth oxyselenide (Bi2O2Se). This development has potential ...
Medical Xpress / Huntington's disease offers a rare clean test case for brain research
Neuroscience rarely enjoys clean experiments. Most brain disorders are mosaics of risk genes, aging, lifestyle and chance that leave their origins obscured. Huntington's disease (HD) is different. It begins with a single ...
Medical Xpress / Baby milk toxin risk 'low' after recalls: EU agencies
Widespread recalls of powdered milk for infants mean the risk of exposure to a toxin that can cause nausea and diarrhea are now low, two EU agencies said on Thursday.
Medical Xpress / Researchers develop RNA-activated implant to stimulate nerve regrowth after spinal cord injury
Researchers from RCSI University of Medicine and Health Sciences have developed a novel implant that delivers tiny growth-promoting particles directly to injured nerve cells, helping them to regrow after spinal cord injury. ...
Medical Xpress / Scalable human neuron networks reveal brain-like rhythms and how drugs reshape them
An EEG (electroencephalogram) is a painless test that uses small sensors placed on the scalp to measure the brain's electrical activity. It provides a real-time readout of brain "waves"—rhythms generated by large groups ...
Medical Xpress / Peanut butter sold in 40 states recalled over possible plastic contamination
If you have peanut butter at home, federal health officials say it's worth taking a closer look. The U.S. Food and Drug Administration (FDA) has announced a recall of more than 20,000 peanut butter products after pieces of ...
Medical Xpress / England has a chronic shortage of family doctors, according to a recent analysis
Four-fifths of England's integrated care boards (ICBs)—responsible for planning health services for their local population—would need to at least double their number of general practitioners to meet staffing standards ...
Medical Xpress / Study uses urine screening to detect alcohol use in early pregnancy
Previous reports have indicated that between 20% and 60% of pregnant women in Ireland consume alcohol during pregnancy. Data on alcohol consumption by pregnant women in Ireland have previously only been collected through ...
Medical Xpress / NIH institute told to drop 'biodefense' and 'pandemic preparedness' language from website
As new infectious threats emerge worldwide, a key U.S. health agency is quietly stepping away from language tied to pandemic planning, a change some experts warn could leave Americans less protected when the next crisis hits.
Tech Xplore / Phosphorus addition could unlock safer, high-performance sodium-ion batteries
Researchers at Kogakuin University have discovered that adding phosphorus (P2O5) to sodium-yttrium-silicate glasses significantly enhances their performance as solid electrolytes for next-generation sodium-ion batteries. ...
