Medical Xpress / Summer sun fails to fix vitamin D gap in at risk groups
Vitamin D levels remain low all year-round in key at-risk groups in England, challenging the belief that summer sunlight is enough to restore them.
Phys.org / Tanzania's iconic heritage sites face damage from state-backed tourism
Assessment of four heritage sites in Tanzania finds that all are under threat from the institutions meant to steward them, prioritizing income from tourism over the sites' preservation and refusing to engage with community ...
Medical Xpress / Women face higher anxiety, depression rates as experts urge mental health care overhaul
Women make up half the world's population yet are the focus of relatively little research, leading to deficits in their mental health care. A Perspective shares key takeaways from the National Academies of Sciences, Engineering, ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Quantum light gives a 20-fold boost to ultrafast laser processes
Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
Phys.org / Nitric oxide overload jams plant immune signals, researchers find
A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings.
Tech Xplore / New York state legislature passes one-year data center moratorium
New York's state legislature passed a bill Thursday night that would prevent permits from being issued for the construction of new data centers for a year, potentially the first law of its kind in the United States.
Phys.org / Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals
An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by raising the ...
Tech Xplore / Atomic swap can improve phosphate cathodes for high-energy sodium-ion batteries
Most smartphones, portable computers and other devices on the market today are powered by lithium-ion (Li-ion) batteries. While these rechargeable batteries perform remarkably well, they are based on lithium, which is not ...
Science X / Universal aging clock predicts death risk across multiple mammalian species
What's common between rats, humans, dogs and dolphins? We are all mammals, and one day will be the last day of our lives. A multinational team of researchers have now given us a powerful molecular clock that, with the help ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
