Tech Xplore / Why AI may boost carbon emissions instead of cutting them
AI data centers get a bad rap, not least because of concerns that they drive climate change by consuming massive amounts of electricity. But one potentially larger impact of AI on global carbon emissions may be that it's ...
Phys.org / Minnesota iron ore could be key to sustainable and lower cost semiconductor
For the first time, researchers at the University of Minnesota Twin Cities have demonstrated that the low-purity iron ore prevalent in Minnesota can be used to create semiconductor-quality iron sulfide, also known as "fool's ...
Phys.org / First evidence of Neanderthal bone tool use in Romania discovered
Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.
Phys.org / Scientists develop method to deliver sugars directly into cells
Sugars, or glycans, play a crucial role in biology—from cell signaling and recognition to interactions with pathogens. Changes in glycosylation are also associated with diseases including cancer. But studying glycans poses ...
Phys.org / Rapid warming may tip Atlantic circulation at 2°C, while slower warming may avert collapse
For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC) could come to a halt if the world warms too much. New research from Utrecht University shows that this picture is ...
Medical Xpress / A few minutes of sprinting could make a bigger impact than 90 minutes of moderate running
Three minutes of sprinting can do something that 90 minutes of moderate exercise apparently cannot: dramatically reshape the molecular contents of the bloodstream. Rockefeller researchers comparing different intensities of ...
Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Tech Xplore / Light-emitting textile sensors could optimize prosthetic fit and comfort
Prosthetics are a fact of life today. It's estimated that more than 50 million people globally—some 2 million of them in the United States—have lost a limb, and most could benefit or already do benefit from artificial limbs ...
Phys.org / Arctic balloon samples trace marine sugars from the ocean to cloud-forming heights
Salt and sugar from the sea can rise as far as the free troposphere, thereby influencing both cloud formation and the Arctic climate. This is the finding of balloon measurements carried out by a team of researchers on Spitsbergen ...
Phys.org / Melting diamond could unlock triple fusion gain and the secrets of ice giant planets
Diamond is more than a dazzling gem—the extremely hard form of carbon makes up the pellet that encases fuel for inertial confinement fusion, and scientists believe it rains down deep inside ice giant planets like Neptune ...
Medical Xpress / Revived rhenium isotope generators answer call for prostate cancer research and other therapies
Haswitha Sabbineni has an idea that could lead to a targeted treatment for prostate cancer. To obtain the rare isotope she needed to test the treatment, she turned to the Department of Energy's (DOE) Oak Ridge National Laboratory ...
Phys.org / Nature's original bioplastic may have fed animals for hundreds of millions of years
Long before humans discovered biodegradable plastics, microorganisms had already invented their own. Many bacteria and archaea produce natural bioplastics called polyhydroxyalkanoates (PHAs), storing them inside their cells ...
