Phys.org / Baseline tool could separate alien life signals from geology on ocean worlds
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Medical Xpress / Topical ivermectin and encapsulated benzoyl peroxide work better than metronidazole for rosacea
Topical ivermectin and encapsulated benzoyl peroxide are more efficacious than metronidazole for adults with rosacea, according to a review published online July 1 in JAMA Dermatology.
Phys.org / Island life changed how Brazil's Noronha skink reproduces, but the lizard's strategy might be failing
Visitors to the Fernando de Noronha archipelago, located about 340 miles (545 kilometers) off the coast of Pernambuco in northeastern Brazil, soon notice a small lizard. Seemingly ubiquitous, it roams among rocks, trails ...
Phys.org / Evidence of elusive high-energy gravitons in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a ...
Phys.org / Metallic rutile oxides break the rules of cooling
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...
Phys.org / Magnetic octupole model captures domain-wall motion in noncollinear antiferromagnets
Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have developed the first magnetic multipole-based micromagnetic model for antiferromagnets. Published in Applied Physics ...
Phys.org / Quantum computers model nine fusion fuel material configurations for first time
A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular configurations of a promising material to produce fuel for fusion energy—the first known instance of such computations ...
Phys.org / How approaching sounds can warp your perception of time
Everyone's perception of time is unique. It is a subjective experience shaped by factors such as age, emotions, memory and environmental contexts. And it may also be influenced by background noise, as scientists have demonstrated ...
Medical Xpress / Modern IVF achieves higher success rates with single embryo transfer, major study finds
Modern IVF treatment can now achieve substantially higher success rates than historical approaches while dramatically reducing twin and triplet pregnancies, according to new research presented at the 42nd Annual Meeting of ...
Medical Xpress / Not all birth controls are equal, some are linked to higher risk of brain tumors, study finds
Meningiomas are the most common brain tumors in adults, accounting for 38% to 42% of all primary central nervous system tumors. According to 2021 WHO data, 874 million of the world's 1.9 billion women of reproductive age ...
Medical Xpress / Five-agent AI team could speed clinical trial design using real-world patient records
An artificial intelligence system that operates like a collaborative team of medical experts could accelerate clinical trial design, one of the most difficult steps in drug development, according to a new study by Weill Cornell ...
