Medical Xpress / Softening aging ovaries could help extend fertility as women get older
Fertility declines as women get older for many reasons, such as a drop in egg quality, decreased follicle numbers and hardening of ovarian tissues. That's a problem for would-be mothers in many countries who prefer to have ...
Phys.org / Capturing the cosmic 'drift' before a star is born
Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of ...
Phys.org / New 200Gbps photodetector doubles optical reception capacity for data centers
Korean researchers have developed, for the first time in Korea, a 200Gbps-class photodetector device for use in hyperscale AI data centers and 5G/6G mobile communications infrastructure. The technology enables ultrahigh-speed ...
Phys.org / When disaster recovery becomes a way of life: Community disaster fatigue is on the rise with more frequent floods
Flash flooding has been tearing up communities across the U.S., with heavy downpours sending creeks and rivers rushing over their banks from Texas to Kentucky, across the Midwest and into the Mid-Atlantic states and the Northeast. ...
Phys.org / Nanoplastics found in Antarctic soils for first time, suggesting long-range atmospheric transport
Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer ...
Phys.org / Shrimp feeding behavior observed under simulated microgravity
The Space Aquaculture Project at Okayama University of Science is an ambitious research initiative aimed at cultivating fish and crustaceans on the moon and Mars, which are expected to serve as food production bases for future ...
Phys.org / Big bees have the most to lose as global CO₂ levels rise: New research
Pollinators—including bees, flies, wasps, moths, butterflies and some nectar-loving birds—are a cornerstone of our natural environment. By helping plants reproduce, they keep our ecosystems healthy and ensure we can grow ...
Phys.org / Floating-electron catalyst withstands week in air while making ammonia under milder conditions
A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by ...
Phys.org / Heavy traffic can turn flower-rich verges into bumblebee traps, study finds
Flower-rich road verges may attract hungry bumblebees, but at the same time, they can be dangerous for the buzzing insects—if traffic is too heavy. The new research from Lund University in Sweden examined the role roadsides ...
Medical Xpress / Study finds obesity 'fuels' leukemia, but a combo using popular weight-loss drugs may stop it
Obesity can act as fuel for leukemia, according to a study led by Indiana University School of Medicine scientists. To help patients facing aggressive blood cancers overcome this metabolic risk, researchers identified a potential ...
Phys.org / Evidence of elusive high-energy chiral graviton excitations 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 / JWST's 'overmassive' early black holes may not be so massive after all
Astronomers studying a population of unusually X-ray-silent and overmassive black holes discovered by the James Webb Space Telescope have found that they may not be as massive as they appear. The new paper, outlining a plausible ...
