Phys.org / Vapor-phase synthesis of MXenes could expand their technological applications
MXenes are two-dimensional nanomaterials first synthesized at Drexel University in 2011. They have been recognized by the International Union of Pure and Applied Chemistry as an emerging technology with "true potential to ...
Phys.org / What ancient Mars rocks reveal about its buried carbonate stores
Carbonate minerals are among the best records of past liquid water on Mars: They form when water carrying dissolved carbon dioxide reacts with rock, and their composition reflects the chemistry of both. Yet Mars has surprisingly ...
Phys.org / Amazonian study identifies most effective ways of conserving biodiversity and carbon
As the 2026 El Niño intensifies across the Amazon, new research highlights the urgent need to better protect the region's remaining forests from disturbances.
Phys.org / Endurance running or endurance diving—which came first?
A new study combines paleoanthropology and diving physiology to address a fundamental question in human evolution: Why did humans evolve their exceptional aerobic endurance? Did our ancestors begin endurance running to exhaust ...
Phys.org / Handheld scanner delivers lab-quality chemical composition maps using infrared light
Researchers have developed a compact, handheld mid-infrared imaging spectrometer that can produce high-resolution chemical maps of a sample without using stains or labels. With further development, the handheld device might ...
Phys.org / Earth's atmosphere is getting less dusty: That could be adding to global warming
Atmospheric desert dust has long swirled around the globe, but a new UCLA study presents the strongest evidence yet that global dust is mysteriously decreasing. Because atmospheric dust has a slight overall cooling effect ...
Phys.org / Microfluidic device simulates human tissue and offers an alternative to animal testing
Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have developed microfluidic technology that can grow cells in three dimensions (3D). The goal is to conduct toxicity tests on new products by ...
Phys.org / Decoding the DNA switches behind gene regulation
Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...
Phys.org / Moles' wide-armed posture reshapes how their shoulder bones carry loads
While the scapula is the primary bone supporting the body in terrestrial quadrupedal mammals, an analysis of internal bone structure in underground moles (family Talpidae) showed a more important role for the clavicle.
Phys.org / Robotic lab sets up and runs optics experiments on demand
Every new generation of phone display, television screen and solar panel is the result of precision optics experiments, which use lasers and other light sources to measure the optical properties of candidate materials. These ...
Phys.org / Why global wind energy may stay steady even as storm tracks shift poleward
Understanding how wind changes in response to global warming is necessary for accurately modeling climate and weather, identifying risks to infrastructure, and assessing global wind power capacity.
Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals
To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...
