Phys.org / What happens inside a wildfire? A Ph.D. student is finding out
What happens during a wildfire? The short answer is: much more than we know. As wildfires burn through trees, grasses and other vegetation, heat from the flames sets off thousands of chemical reactions at once. Molecules ...
Phys.org / Mapping the 'hidden highways' of Mexico's illegal wildlife trade
For decades, wildlife traffickers have illegally captured and sold hundreds of thousands of wild parrots native to Mexico. Despite changes to international wildlife laws, the conservation status of these birds has continued ...
Tech Xplore / Who does AI consider an expert? New benchmark shows bias across 22 LLMs
AI chatbots powered by large language models (LLMs) are widely used as recommender systems. While accelerating access to information, AI can also give factually incorrect responses or propagate societal biases.
Medical Xpress / Altered ribosomes help explain how an enzyme fuels tumor growth
A new Northwestern Medicine study has identified a previously unknown mechanism by which an enzyme promotes cancer cell proliferation, establishing it as a promising therapeutic target for cancer, according to findings published ...
Phys.org / Bacteria from ancestral wheat microbiomes help protect plants against root rot fungus
In the journal npj Biofilms and Microbiomes, researchers from the Brazilian Agricultural Research Corporation (EMBRAPA) and the University of São Paulo (USP) describe the role of three bacteria in suppressing a soil-borne ...
Phys.org / A 4-star system caught eclipsing itself in a way never seen before
Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While each pair eclipses its own two stars, as usual, ...
Phys.org / How atmospheric dryness limits increases in typhoon rainfall
Under global warming, scientists have widely expected tropical cyclones (including typhoons and hurricanes) to bring more intense and frequent rainfall. The underlying physics seems intuitive: Rising temperatures allow the ...
Phys.org / Chemicals banned in the 1970s still widely detected across Europe, new study finds
A new study has found that regulatory restrictions introduced more than half a century ago have failed to eliminate contamination from banned chemicals across Europe. Researchers say they detected banned chemicals in air, ...
Phys.org / Mule helps scientists build the clearest horse and donkey genomes yet
A mule has helped researchers build the most complete reference genomes to date for horses and donkeys, giving scientists access to complex regions of DNA that earlier versions could not fully capture.
Phys.org / A 2-degree twist creates a nanoscale grid that traps light energy at room temperature
You may have once tried taking a close-up picture of a computer screen and noticed a wavy, rippling effect. This optical effect occurs whenever two fine, repeating grids overlap and slightly misalign, such as when the pixel ...
Tech Xplore / Copper tubes gain 5.5-fold condensation heat-transfer boost from water-shedding coating
A technology that boosts condensation heat transfer performance by up to 5.5 times that of conventional copper surfaces has been developed by helping water droplets form more readily and detach more quickly. It is expected ...
Phys.org / Woodlands and other natural spaces could help cities cope with extreme heat
Green and blue spaces, such as woodlands and riversides, could provide a vital line of defense for cities facing increasingly hot summers, according to new research from the University of Surrey.
