Medical Xpress / 1 in 3 Americans say sacrificed for health care costs
One in three Americans said they made some sacrifice last year—like skipping a meal or rationing medicine—to cover health care costs, according to a survey released Thursday.
Phys.org / US data shows Arctic winter sea ice could break last year's record low
Arctic sea ice is headed for one of its smallest winter peaks on record, an AFP review of U.S. data showed Wednesday, as climate change shrinks the region's frozen cover and heightens geopolitical tensions.
Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
Phys.org / 'Superconducting dome' hints at high-temperature superconductivity in thin nickelate films
Superconductivity is a quantum state of matter characterized by an electrical resistance of zero and the expulsion of magnetic fields at low temperatures below a critical point. Superconductors, materials in which this state ...
Phys.org / Inland China experienced typhoon-related population decline 3,000 years ago, according to 'oracle bones,' AI and physics
Evidence suggests that China's "cradle of civilization" experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient ...
Phys.org / Your cat is likely to live longer if you don't let them roam—new study
We all know cats represent a major threat to native animals and birds. Australia's 5.3 million domestic cats kill a total of 546 million animals each year in Australia. What's less well known is allowing your domestic cat ...
Phys.org / What's it like to be a bat? Scientists develop new solution to the puzzle of animal minds
In 1974, philosopher Thomas Nagel posed a deceptively simple question: "What is it like to be a bat?" His point wasn't really about bats. He was offering a provocative challenge about the limits of understanding another mind: ...
Tech Xplore / Can AI read papers like a scientist? A new benchmark shows where LLMs fail
To stay up to date and work forward in their fields, scientists must have at their fingertips and in their minds thousands of published studies. Large language models (LLMs) show promise as a tool for exploring the vast scientific ...
Phys.org / The Rubin Observatory's LSST will detect imminent impactors before they crash into Earth
The Vera Rubin Observatory (VRO) has barely begun observations and is already wowing us. Images like its Cosmic Treasure Chest have us anticipating even more cosmic glory. And when the observatory sent out 800,000 alerts ...
Medical Xpress / AI meal plans for teens may undercount calories by nearly 700, study suggests
Many teens dealing with weight issues are turning to AI models to help them create meal plans with the aim of losing weight. But a new study shows that the resulting plans may not always adequately cover necessary nutrients ...
Tech Xplore / The AI that taught itself: How AI can learn what it never knew
For years, the guiding assumption of artificial intelligence has been simple: an AI is only as good as the data it has seen. Feed it more, train it longer, and it performs better. Feed it less, and it stumbles. A new study ...
Phys.org / Chemical shifts help track molecules breaking apart in real time
When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane ...
