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 / Missing link in evolution of ancient fish found in 150-year-old museum specimen
A new species of coelacanth has been identified from a 150-year-old fossil housed at London's Natural History Museum. Former University of Portsmouth paleontology student Jack L. Norton located the coelacanth, which provides ...
Phys.org / Inside the competition for capital at some of the world's biggest banks
As the U.S. economy becomes more consolidated, the strategic decisions of senior leaders at leading companies carry ever-greater weight. A lot is riding on how these companies are run, yet in most cases, their day-to-day ...
Phys.org / Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food
Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. ...
Phys.org / NASA's Curiosity rover uncovers metal‑rich hotspot tied to ancient Martian lake
A team of scientists using the ChemCam instrument on NASA's Curiosity Mars rover has discovered the highest amounts of iron, manganese, and zinc ever found together in Gale Crater on Mars. Minerals with these metals were ...
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Medical Xpress / A blueprint for holistic cardiovascular implantable electronic device lead management and lifelong patient safety
New evidence on cardiovascular implantable electronic devices (CIED) lead management and the burgeoning development of new CIED technologies have contributed to the field's rapid evolution in the last decade. The new "2026 ...
Phys.org / Tiny satellites face big data limits: How foldable antennas could change CubeSat missions
An origami-inspired reflectarray antenna developed by researchers at Institute of Science Tokyo enables CubeSats to achieve high antenna gain while fitting within the tight size constraints of small satellites. Weighing just ...
Medical Xpress / Less than half of pregnant women with opioid use disorder receive meds
Less than half of pregnant women with opioid use disorder (OUD) receive medications for OUD (MOUD) during pregnancy, according to a study published online April 22 in Drug and Alcohol Dependence.
Phys.org / How cells turn mechanical forces into biochemical signals
Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. ...
Medical Xpress / Two-faced protein discovery may explain why leukemia drugs fail or succeed
A KAIST research team has identified the real reason why anticancer drugs kill cancer cells—targeted anticancer therapies do not simply block cancer proteins but rather shut down the "protein factories" inside the cells, ...
Medical Xpress / Optimal sleep may reduce dementia risk in patients with focal epilepsy
Optimal sleep duration is associated with better executive function, with a significantly higher impact of optimal sleep among those with focal epilepsy, according to a study published online April 22 in Neurology.
