Dialog / Can front-of-pack labels ease hospital strain? A Canadian blueprint as the U.S. considers FDA's Nutrition Info box
Hospital beds are a brutally concrete resource. When they're full, surgeries get delayed, hallways become overflow wards, and staff burn out. So a question I keep coming back to is simple: can the way we label food, those ...
Phys.org / Natural magnetic materials can control light in unprecedented ways
Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction, could transform ...
Phys.org / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena
The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...
Dialog / Using data to reduce subjectivity in landslide susceptibility mapping
In recent years, numerous landslides on hillsides in urban and rural areas have underscored that understanding and predicting these phenomena is more than an academic curiosity—it is a human necessity. When unstable slopes ...
Phys.org / Nanotubes with lids mimic real biology
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that ...
Medical Xpress / Common bacteria discovered in the eye linked to cognitive decline
Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer's disease, according to a study from Cedars-Sinai. Published in ...
Medical Xpress / Night owl or early bird? Study finds sleep categories aren't that simple
The familiar labels "night owl" and "early bird," long used in sleep research, don't fully capture the diversity of human internal clocks, a new study has found. The McGill University-led study published in Nature Communications ...
Phys.org / Perseverance rover completes first AI-planned drive on Mars
NASA's Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency's Jet Propulsion Laboratory in Southern California, ...
Phys.org / As Rubin's survey gets underway, simulations suggest it could find about six lunar-origin asteroids per year
Most near-Earth asteroids are thought to drift in from the main asteroid belt. But a small subset may have a much closer origin: the moon. One intriguing example is 469219 Kamoʻoalewa (2016 HO3), an Earth quasi-satellite ...
Phys.org / AI model forecasts coral heat stress on Florida reefs up to six weeks ahead
Scientists have created an AI model that forecasts moderate heat stress—a major precursor to coral bleaching—at sites along Florida's Coral Reef up to six weeks ahead, with predictions generally accurate within one week. ...
Medical Xpress / Chemo before 3 pm could be more successful for lung cancer patients
Patients with advanced lung cancer who received immunochemotherapy before 15:00 (3 p.m.) had a more delayed disease progression than patients receiving treatment later in the day. The findings, published as part of a randomized ...
