Medical Xpress / New brain scan detects Alzheimer's tau earlier than current standard
A new brain imaging test can detect a key hallmark of Alzheimer's disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh ...
Phys.org / Electrical 'knob' can switch light on, off and tune intensity at the nanoscale
Physicists from Emory University have led work to develop a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical "knob." The paper is published in the journal ...
Phys.org / Quantum vibronics research points to future energy and computing technologies
Scientists at the University of California, Riverside are making breakthroughs in understanding how quantum wave functions move across ultra-thin materials—research that could eventually improve solar energy technologies ...
Phys.org / Global food shock model reveals self-sufficiency alone may not prevent crises
Global food systems are fragile. Recent shocks such as the closure of the Strait of Hormuz and the Russian invasion of Ukraine have raised prices and exacerbated food insecurity. Governments are increasingly trying to shield ...
Science X / The mental cost of skipping meals may run higher than most people realize
Skipping a few meals here and there, or eating whenever one can make time in their schedule, might seem like a benign act. Research, however, shows that these habits are far from being harmless. A recent large-scale study ...
Tech Xplore / Sodium-ion batteries could become a low-cost rival to Tesla's batteries
A popular sodium-ion battery designed by the company Hina and used in cars and large-scale energy storage systems in China matches performance parameters and production quality of Tesla's lithium-ion batteries, finds new ...
Phys.org / Earth's oxygen-rich atmosphere may owe its existence to cold subduction
Earth was mostly devoid of oxygen for much of its 4.5 billion year lifetime. That is, until certain processes started to allow for the eventual buildup of oxygen up to the levels we have now (around 21% of the atmosphere). ...
Phys.org / New Gulf Coast plan uses ocean technology to trap carbon dioxide
The motion of the ocean may be the key to removing carbon dioxide from the atmosphere, so University of Houston researchers set out to determine which U.S. coastlines are best suited for the process in a new study.
Phys.org / Rare observations reveal an X9 solar flare before it erupts
Solar flares are powerful bursts of radiation from the sun's surface, which can wreak havoc on Earth's power grids, damage orbiting satellites, and pose serious radiation risks to astronauts. Yet despite decades of study, ...
Medical Xpress / AI suggests simple food swaps to make meals healthier and cheaper
An artificial intelligence framework that suggests just one to three ingredient swaps can make meals meaningfully more nutritious and less expensive, according to a new study published in PLOS Digital Health by Trevor Chan ...
Phys.org / Sensitivity of Antarctic ice to climate change sharply increased after ice age shift, study shows
A new study published in the journal Nature Geoscience by researchers at the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea shows that the Antarctic ice sheet became more sensitive to climate ...
Phys.org / Outdoor lights may keep mosquitoes biting and breeding deeper into autumn
In some parts of the world, autumn brings welcome relief from mosquitoes, such as the Northern house mosquito (Culex pipiens). As the days grow shorter, the waning light is a signal for them to enter a winter state of dormancy ...
