Phys.org / Millions of atoms, shifting bonds—new software brings living chemistry into view
Chemical reactions drive life. They ensure that cells obtain energy, proteins perform their functions, and DNA changes under certain conditions. However, many of these processes occur on extremely small scales—so small and ...
Phys.org / Elusive tularemia proteins reveal possible treatment target in rare tick-borne disease
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Symptoms of infection can include fever, swollen lymph nodes, and—in some cases—pneumonia. What ...
Phys.org / Wildfire-driven deforestation rates in California among highest in world
California has one of the highest rates of wildfire-driven deforestation in the world, and the trend has accelerated over the past three decades, according to a study from the University of California, Davis. The study, published ...
Phys.org / Engineered soil bacterial protein kills colorectal cancer cells by targeting their mitochondria
Researchers at Umeå University have turned a protein from soil bacteria into a potential new weapon against colorectal cancer. Their study published in Cell Death Discovery shows how an engineered bacterial protein can trigger ...
Phys.org / DNA's physical form helps direct gyrase activity and could reshape antibiotic design
New analytical methods developed at Baylor College of Medicine and collaborating institutions have increased our understanding of how bacteria manage DNA. The methods have enabled researchers to uncover how the sequence, ...
Phys.org / Beneath Arctic ice, a vast fossil fuel footprint is colliding with Indigenous lands and wildlife
Arctic fossil fuel development shows significant overlaps with Indigenous communities and ecologically sensitive areas, which might support calls from some scientists to keep Arctic fossil fuels in the ground, according to ...
Phys.org / Chalk-stream salmon could become an official sub-species
Chalk-stream salmon should be officially classified as a sub-species, new research suggests. Scientists from the University of Exeter and INRAe (France) carried out detailed genetic testing of salmon from 42 rivers in England, ...
Phys.org / First direct nanomagnet measurement finds switching attempts far slower than long-assumed
A compass always points north—or does it? Magnets normally maintain a stable direction of magnetization, pointing from south to north (S→N). However, this direction can change under strong magnetic fields or heat. For example, ...
Phys.org / What's in a name? Study finds two dahlia-damaging viruses are variants of same species
For decades, two different viruses were believed to be responsible for a common, untreatable disease in dahlias, a colorful, high-value flower grown worldwide. Virologists at Washington State University have now learned that ...
Phys.org / ATLAS sets record limits on Higgs boson's self-interaction
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This "self-coupling" could help explain the evolution of the early universe and the mechanism that gives mass to elementary ...
Phys.org / Turning vibrations into value—a new catalyst converts CO₂ into useful CO
Researchers at The University of Osaka have developed a catalyst that uses vibrational energy to convert carbon dioxide (CO2) into carbon monoxide (CO), an important industrial feedstock. The work, published in the Journal ...
Phys.org / Hidden nest cameras debunk long-standing myth about how cuckoos lay their eggs
An international team of ornithologists has overturned one of the oldest assumptions in natural history by directly documenting how common cuckoos lay their eggs in host nests located inside cavities. The findings, published ...
