Phys.org / 'Check your ingredients': A new blueprint for using Fermi's 'Golden Rule'
Underpinning much of modern technology, from smartphones to scanning tunneling microscopes to particle colliders, is Fermi's Golden Rule. Named for 20th-century Italian American physicist Enrico Fermi (but actually discovered ...
Phys.org / Krill buildup could slow fin whale filter-feeding unless baleen stays 15% clear
Usually there's safety in numbers, but it doesn't always work that way. Fin whales (Balaenoptera physalus) filter-feed on immense shoals of krill, engulfing colossal mouthfuls of water containing up to 144 kg of the crustaceans. ...
Tech Xplore / At the nation's only all-digital nuclear reactor, engineers conduct the first experiments of their kind in the US
Underground on Purdue University's campus is the only nuclear reactor of its kind in the U.S. Although used only for research purposes—the total energy the reactor generates is equivalent to that used by 10 microwave ovens—Purdue ...
Phys.org / Collective agreements are least common where workers need them most
Workers earning the lowest wages are the least likely to be covered by collective agreements in Germany, despite being the group for whom these protections are arguably most important. In 2021, only 34% of workers in the ...
Phys.org / JWST finds the most distant barred galaxy candidate in the early universe
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...
Phys.org / Heat waves push tropical forests past photosynthesis limits across 57 million hectares
As heat waves continue one after another, we are feeling their effects on our own bodies: It becomes harder for us to function normally. Trees also have their limits when temperatures are too high. Above a certain critical ...
Tech Xplore / New AI add-on helps developers automate everyday programming tasks
Developers are increasingly relying on large language models (LLMs) for everyday computing tasks such as fixing bugs, explaining code and automating text-processing tasks like filtering logs.
Tech Xplore / Meet Biomni—an AI-powered biomedical co-scientist
In creating a comprehensive, AI-enabled research agent for the biomedical sciences, Stanford University researchers hope to speed innovation by eliminating the tedium of scientific legwork. Biomni, an AI-powered, multiskilled ...
Phys.org / The ghost in Orion's shell: Hydrogen maps show repeated stellar feedback sculpted around Orion Nebula
An international team led by Juan Diego Soler at the University of Vienna used two of the world's most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest ...
Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...
Phys.org / New sensors capture warning signs before fish deaths in Lake Victoria
Researchers from King's College London recorded the warning signs of a major low-oxygen event in Lake Victoria just hours before fish deaths were reported by local communities, demonstrating why earlier warning systems are ...
Phys.org / Self-propelled microparticles scrub stubborn biofilms, improving wound care and instrument cleaning
Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at ...
