Phys.org / Gulf Stream shifted north during 12,900-year-old cold snap, first direct evidence shows
During an abrupt global cold snap nearly 13,000 years ago, the Gulf Stream ocean current shifted farther north, temporarily disrupting eastern Canada's oceanic ecosystems, a process that could happen again as the climate ...
Tech Xplore / New strategy enhances oxygen reduction in zinc-air batteries
Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding ...
Medical Xpress / Why tiny amounts of vitamin B12 matter more as we age
Two micrograms is an almost unimaginably small amount. It weighs less than a tiny fragment of a grain of table salt. Yet adults need only around this amount of vitamin B12 each day, depending on the guideline used, to support ...
Phys.org / Jurassic viral gene may have helped apple snails start laying eggs on land
Pomacea canaliculata, commonly known as the apple snail, is a pest commonly found in Hong Kong's wetlands and farmlands. It feeds on aquatic plants and produces toxic pink egg masses resembling miniature grapes that adhere ...
Medical Xpress / Traditional tertiary teaching models shortchanging neurodivergent students in health care studies
Recent Deakin research into the experiences of neurodivergent students studying for future health care careers showed many experience stigma, inadequate help in classroom and clinical settings, and hard-to-navigate support ...
Phys.org / New species of Middle Miocene bear-dog described in tribute to Salvador Moyà-Solà
A research team with the participation of the Institut Català de Paleontologia Miquel Crusafont (ICP) has described a new species of extinct carnivore from fossil remains recovered at the Els Casots site (Subirats, Alt Penedès). ...
Medical Xpress / Our brains may be automatically filtering out negative words
We tend to assume that emotionally charged words are more likely to grab our attention. An insult shouted across a crowded room or a disturbing phrase overheard on television can seem impossible to ignore. But a new study ...
Phys.org / Nuclear clocks tick for the first time
Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca Toscani De Col and colleagues ...
Medical Xpress / Faulty protein cleanup gene tied to severe early-onset neurological disorders
Though protein clumps associated with Alzheimer's and Parkinson's were discovered more than a century ago, researchers remain largely unable to prevent them from forming or eliminate them from the brain. And though a variety ...
Phys.org / Scientist creates 'mini‑universe' to measure time without a clock
A University of Birmingham scientist has built a "mini-universe" that takes a step toward answering one of science's biggest questions: "What is time?" Publishing his findings in Physical Review Research, Professor Giovanni ...
Phys.org / 'Puffy' super-Neptune emerges 383 light-years away with a density of just 0.4 g/cm³
Using the Subaru Telescope, astronomers have conducted follow-up observations of a recently discovered exoplanet known as TOI-1883 b. Results of the new observations, published June 5 on the arXiv preprint server, indicate ...
Phys.org / Engineering quantum Hall stripes in 2D materials inside electromagnetic cavities
Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly promising for the development of ultra-efficient electronic devices, quantum processors, highly precise ...
