Phys.org / Metal deposits reveal how ice ages reshaped oxygen levels across Earth's oceans
Earth's oceans repeatedly lost oxygen and produced metal deposits during the planet's deepest ice ages. An international team of researchers analyzed manganese and other chemical signatures preserved in more than 27,000 ancient ...
Phys.org / Pixel patterns harness diffraction for faster, more accurate nanoscale 3D printing
Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a challenge that has limited the technology's ...
Phys.org / Forest floors reveal overlooked seed dispersers: Slugs, beetles and crabs spread viable seeds
A review led by the School of Biological Sciences at The University of Hong Kong (HKU) has revealed that tiny ground-dwelling invertebrates are overlooked but important seed dispersers, challenging the traditional focus on ...
Phys.org / AI models atom movement to predict solid-state reaction pathways, including impurities, in minutes
A research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has successfully demonstrated an AI modeling approach that accurately and rapidly predicts how reactions between solid materials ...
Phys.org / Light controls nanoscale 'bubble' domains in a ferroelectric crystal
Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, ...
Phys.org / Discarded rice husks capture toxic dyes, offering a reusable water filter
Rice is the most-eaten food on the planet, and its discarded outer husk results in some 300 billion pounds of waste per year. FIU chemistry researcher Islam Ibrahim Hussein says the inedible castoffs could be the key to cleaner ...
Phys.org / Cells of the same age can follow sharply different biological aging paths
New research reveals that cells of the same chronological age can follow dramatically different biological aging paths, offering new insights into cancer, neurodegeneration and the fundamental biology of aging. Rather than ...
Phys.org / Humpback whales match song themes to dive phases, tags reveal
For male humpback whales, singing is serious business. Their haunting, complex songs can last for hours and travel for miles underwater, playing a central role in reproduction during the winter breeding season. But despite ...
Phys.org / Nanopore method improves detection of cyanobacteria toxins in lake water
Cyanobacterial blooms, like the ones that occur in Lake Geneva, are rapid, dense growths of photosynthetic bacteria in fresh and marine waters that can threaten the health of swimmers and their pets.
Phys.org / Over 100 South American lakes could become climate-change early-warning observatories
More than 100 shallow lakes stretching over 1,000 kilometers (620 miles) along the Atlantic coast of southern Brazil and Uruguay could become one of the world's most important natural laboratories for understanding how climate ...
Phys.org / Kids who start social media earlier may do worse at school
Students who open a personal social media account earlier in adolescence appear to perform worse on later standardized tests, according to a study in Nature Human Behaviour based on 5,227 Italian students. The authors speculate ...
Phys.org / Scientists watch, molecule by molecule, as cell helpers rescue problem proteins
University of Wollongong (UOW) scientists have uncovered, for the first time, exactly how two of the cell's "helper" proteins operate as a rescue crew for misfolded proteins, a discovery that sheds new light on the molecular ...
