Phys.org / New method brings single-particle quality control to nanocrystal manufacturing
Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not ...
Phys.org / X-ray tracking reveals uneven expansion in young supernova remnant G292.0+1.8
By analyzing data from NASA's Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova remnant known as G292.0+1.8. Results of the new study, published June 29 on the arXiv preprint server, ...
Phys.org / Immune cells get transformed into fungus-fighting nanoparticles
Tiny particles made from the membranes of human immune cells could offer a promising new way to fight fungal infections that are becoming harder to treat. Engineers at the University of California San Diego created antifungal ...
Phys.org / Synthetic rotation brings black hole energy theory into lab, amplifying waves
More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ergosphere—a region of space ...
Phys.org / Saturday Citations: Blue zone longevity; soft tissue find predates dinosaurs; black hole collisions simplified
This week, researchers reported finding nanoplastics in Antarctic soils for the first time, suggesting they were delivered via long-range atmospheric transport. A study associates the use of hormonal birth control with the ...
Phys.org / When species are forced to move: Prediction models underestimate climate-related extinction risk
Climate change threatens many plant and animal species not only when their habitats disappear as climatic conditions change, but also when those habitats shift. In a new study, a team of University of Potsdam researchers ...
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 ...
Phys.org / Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene ...
Phys.org / Cast away: Tracing the voyage of a plastic bottle cap and its hitchhiking marine species
Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells and ocean current simulations. They found 307 organisms, ...
Phys.org / A robot that reads bacteria by touch, without staining or chemical labels
Fast identification of bacteria is important in health care, food safety, environmental monitoring and infection control. One of the most common first steps is gram classification, which separates bacteria into gram-positive ...
Phys.org / Grasses provide most of the world's calories—but we're only now starting to learn how they grow
If we want to dismiss something as irrelevant, we'd say that it's "as boring as watching the grass grow." And yet grasses—including corn, wheat and rice—make up most of the plant-based calories humans eat, as well as most ...
Phys.org / Tiny worms reveal backup circuits that keep survival reflexes from failing
A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered ...
