Phys.org / New shell helps gold nanoparticles keep shape under laser heat longer
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer ...
Phys.org / Brutal field trip provides new insights into Arctic winter
It was the hardest field trip they had ever been on, but the result was both surprising and exciting. After hiking 9 kilometers with a 400-meter elevation gain and carrying heavy backpacks through very rocky terrain, the ...
Phys.org / TriPcides target MRSA, suppress infection and kill dormant bacteria to open a new front against antibiotic resistance
In a new study, researchers show how so‑called TriPcides can target the bacterium Staphylococcus aureus, including antibiotic‑resistant strains such as MRSA. The compounds disrupt the bacteria's ability to cause infection ...
Phys.org / Imperfect polymer sequences still control protein function, revealing new design rules
What happens when a scientific problem seems too complex to solve precisely, yet understanding it could reshape how researchers design new materials and medicines? For decades, much of the polymer science community has relied ...
Phys.org / Decoding the balance between life-and-death proteins
In every organism, the regulation of cell populations is a constant process. This balance relies on a continuous interplay between "guardian" proteins that promote cell survival and "killer" proteins that trigger programmed ...
Phys.org / Grokipedia selectively draws on more-right leaning news sources, says new study
A large-scale analysis of Grokipedia, the world's first AI-written encyclopedia, has found that while many Grokipedia articles closely resemble their Wikipedia counterparts, a substantial subset diverged markedly in style, ...
Phys.org / Molecular net boosts the power of natural biopesticides
Scientists at VIB and Vrije Universiteit Brussel have uncovered a previously unknown mechanism that helps a widely used biological pesticide become more effective. The study, published in Nature Communications, reveals how ...
Phys.org / Supernova dust may be behind one of JWST's biggest puzzles
Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The ...
Phys.org / Debunking a core chemistry concept taught in classrooms everywhere
A new study has revealed that a core idea taught in chemistry classrooms around the world may be wrong. Dr. Edwin Johnson, Lecturer at the University of Newcastle, co-authored the paper published in the Journal of Chemical ...
Phys.org / AI-generated fake citations are flooding scientific literature across publications, scientists warn
The citations at the end of a research paper should represent a solid foundation of existing knowledge about a particular field, a pool of peer-reviewed sources built over years of research and study. However, with the increasing ...
Phys.org / Ultrafast switching device unlocks low-power optical-to-electrical conversion for AI hardware
Modern energy demands are soaring as technologies like AI and IoT become more common, and researchers have been working hard to develop hardware that can keep up. Now, a team of researchers from the University of Tokyo has ...
Phys.org / White hydrogen discovered in billion-year-old Canadian Shield rock points to potential new energy source
Within the Canadian Shield, hydrogen gas is steadily building up naturally among some of the oldest rocks on Earth. Now, for the first time, geochemists at the University of Toronto and the University of Ottawa have measured ...
