Phys.org / AI for molecular simulations may not need built-in physics to deliver strong results
Simulating how atoms and molecules move over time is a central challenge in computational chemistry and materials science. Classical machine learning approaches to molecular dynamics (MD) encode fundamental physical principles ...
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 / Turning four into two: How duplicated genomes become diploid again
Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of the process known as rediploidization. ...
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 / 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 / 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 / New technology helps flat-faced dogs breathe easy
Australian scientists have developed an injectable therapy that helps clear blocked airways in flat-faced dogs. Melbourne-based biotechnology company Snoretox and RMIT University have shown early success using the first therapy ...
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 / 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 / Plants can sense the sound of rain, new study finds
The next time you find yourself lulled by the patter of rain outside your window, think how that same sprinkle might sound if you were a tiny seed planted directly below a free-falling droplet. Would you still be similarly ...
Phys.org / Laser-plasma 'mirror' unlocks a new path to extreme light intensities
An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a practical route to dramatically boosting the intensity of high-power laser light.
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, ...
