Phys.org / Evidence of 'lightning-fast' evolution found after Chicxulub impact
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new research shows that it also ...
Phys.org / Study reveals why light-driven chemical reactions often lose energy before bond-breaking
Florida State University researchers have discovered a pathway within a certain type of molecule that limits chemical reactions by redirecting light energy. The study could enable development of more efficient reactions for ...
Phys.org / Copper-carrying compound targets and kills MRSA bacteria by mimicking iron
A research team at the University of Arizona College of Medicine–Tucson is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant ...
Phys.org / Single enzyme streamlines production of all four RNA building blocks
A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been identified by researchers at the Institute of Science Tokyo. The study was published online in the ...
Phys.org / 3D-printed surfaces help atoms play ball to improve quantum sensors
Scientists have created 3D printed surfaces featuring intricate textures that can be used to bounce unwanted gas particles away from quantum sensors, allowing useful particles like atoms to be delivered more efficiently, ...
Phys.org / AI method advances customized enzyme design
Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection. For example, they make it possible to synthesize chemicals in a more environmentally friendly way, produce ...
Phys.org / Increased soil salinity alters global inorganic carbon storage, finds study
A new global study shows that increasing soil salinity is systematically reshaping the storage and distribution of soil inorganic carbon (SIC), a key but often-overlooked part of terrestrial ecosystems. The findings, published ...
Phys.org / The hidden microbial communities that shape health in space
Microorganisms live in biofilms—the equivalent of microbial "cities"—everywhere on Earth. These city-like structures protect and house microbial communities and play essential roles in enabling human and plant health ...
Phys.org / Living walls boost biodiversity by providing safe spaces for urban wildlife
Living walls—structures housing flowers and plants fitted to the outside of new and old buildings—can significantly enhance the biodiversity within urban environments, a new study has shown.
Phys.org / Expanding existing mines poses overlooked long-term environmental and social risks
Mining companies worldwide are expanding mineral extraction at existing mines, as the rate of opening new sites slows, to meet global demand driven mainly by the need for clean energy infrastructure.
Phys.org / DNA nanodevices reveal acidic nanolayer on lysosome surfaces in live cells
Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is known to regulate cytosolic-side functions such as membrane fusion/fission, movement, and membrane-contact ...
Phys.org / Tuning color through molecular stacking: A new strategy for smarter pressure sensors
Piezofluorochromism, the phenomenon of materials reversibly changing their fluorescent color when pressure is applied, is used to create the pressure sensors used in automotive and medical industries. By monitoring color ...
