Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Medical Xpress / A potential new lymphedema target: Clearing cholesterol deposits to reduce swelling
An international team led by National University of Singapore researchers has linked secondary lymphedema to excessive cholesterol buildup inside skin and around lymphatic vessels. Excess cholesterol deposition tracked with ...
Phys.org / One of the ocean's saltiest regions is freshening: What it means for circulation
The southern Indian Ocean off the west coast of Australia is becoming less salty at an astonishing rate, largely due to climate change, new research shows.
Medical Xpress / FDA expands tater tot recall tied to possible plastic contamination
A recall of frozen tater tots has expanded after federal officials warned that hundreds of thousands of pounds could contain pieces of plastic.
Phys.org / The Hubble tension: How magnetic fields could help solve one of the universe's biggest mysteries
It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.
Phys.org / Polluting the environment for all eternity—and still sticking our heads in the sand
The Kunming-Montreal Global Biodiversity Framework states that plastic pollution must be eliminated by 2030. So why haven't we enacted measures that make a real difference?
Phys.org / Replacing humans with machines is leaving truckloads of food stranded and unusable
Supermarket shelves can look full despite the food systems underneath them being under strain. Fruit may be stacked neatly, chilled meat may be in place. It appears that supply chains are functioning well. But appearances ...
Phys.org / Failed supernova provides clearest view yet of a star collapsing into a black hole
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black ...
Phys.org / Scientists uncover Iron Age origins of Vietnamese tooth blackening practices
Not everyone wants their teeth to be white and gleaming. Tooth blackening is a recognized part of modern Vietnamese culture, and a recent discovery hints that the roots of this practice may stretch all the way back to the ...
Phys.org / Silicon quantum processor detects single-qubit errors while preserving entanglement
Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link between particles that ...
Phys.org / Japan's ancient 'tigers' were actually cave lions, DNA evidence shows
There aren't any native lion or tiger populations living in Japan today, but this was not always the case. Fossil evidence indicates that at least one species of large cat roamed the archipelago during the Late Pleistocene—a ...
Phys.org / How one genome creates two distinct fungal bodies
Creatures that can change from one form to another are a staple of science fiction: Think werewolves and Transformers. Nature, too, has its shapeshifters, such as dimorphic fungi. While scientists have known for some time ...
