Phys.org / AI screens 100,000+ membrane combinations, predicting carbon capture performance within seconds
Reducing carbon dioxide emissions from industrial processes and energy production remains one of the major technological challenges in addressing climate change. Membrane-based gas separation offers an energy-efficient alternative ...
Phys.org / Fastest known Milky Way star offers new test of supermassive black hole's spin
Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its center. The star, named S301, was detected with the European Southern Observatory's Very Large Telescope Interferometer ...
Phys.org / Beijing's isoprene-emitting trees highlight ozone risks in greener, hotter cities
Amid current heat waves, urban greening is once again moving to the center of public debate. Greener cities are generally expected to have cleaner air because trees capture airborne particles, absorb gaseous pollutants and ...
Phys.org / Too much RNA can starve cells of energy, study finds
A new study from researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has uncovered a previously unknown consequence of viral infection: Too much RNA inside a cell can disrupt its ability ...
Phys.org / Peru's highest mountain confirms tropics were a major methane source before the industrial era
A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.
Phys.org / AI prompts offer a new tool for mapping how emotion concepts relate
How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in ...
Phys.org / Foreign tariffs made U.S. whiskey cheaper... depending on where you live
A new study finds that one side effect of Trump-era trade wars has been cheaper whiskey in much of the United States. But if you live in whiskey hubs Kentucky or Tennessee, your prices actually went up.
Phys.org / Climate taxonomy tool turns risk assessments into practical adaptation guidance
As climate impacts such as heat waves, floods and fires intensify worldwide, there is an urgent demand for information on how to respond. IIASA researchers and partners have developed a new tool that meets that need, integrating ...
Phys.org / Neutron capture experiment sheds light on ancient stardust
Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. In an article ...
Phys.org / 'Ecology of fear' can dramatically change the behavior of blue mussels
For a blue mussel, a good meal does not come entirely without risk. Blue mussels feed by filtering microscopic algae from seawater. But some unwelcome guests can slip in along with their food. Tiny parasite larvae can hitch ...
Phys.org / AI flood map reveals 11 million Americans may be omitted from official risk zones
Official flood maps shape disaster preparedness, insurance decisions and urban planning, but large parts of the United States remain unmapped or under-mapped. This means some communities may be left unaware of the risks they ...
Phys.org / Interacting with AI can make people act more like robots
As AI continues to develop at a rapid pace, social robots powered by AI are becoming more commonplace in customer service settings such as retail, hospitality, tourism and health care. But as these robots become smarter and ...
