Phys.org / From toothbrushes to aerospace: Graphene research advances fibers that conduct heat efficiently
KAIST's discovery of graphene oxide liquid crystals in 2011 laid the foundation for 15 years of research worldwide, leading to technologies for producing graphene fibers with high strength and thermal conductivity. The fundamental ...
Phys.org / New method reveals how virus particles can build themselves, molecule by molecule
Oxford University researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The results were ...
Phys.org / Rivers may be carrying more microplastics into the world's oceans than previously thought
Microplastics are a modern environmental menace and a potential threat to human health. These tiny pieces of plastic, measuring from 1 to 5,000 micrometers, come mainly from larger plastics as well as sources such as paints ...
Tech Xplore / NYT alleges Microsoft, OpenAI knew using news content was theft
OpenAI committed "an astonishing theft of unprecedented proportions" when it used millions of news articles to train its artificial intelligence models, The New York Times alleged in a court document unsealed Thursday.
Phys.org / Baby orangutans in India expose 'frightening' scale of trafficking
Five baby orangutans abandoned in an Indian forest have exposed a "massive" exotic wildlife trade, with traffickers smuggling increasingly rare species into the country, experts say.
Tech Xplore / MRI technique eliminates 'dead time' to capture rapidly fading signals, making scans more precise
A team of researchers at the University of Stuttgart has developed a new method that could make MRI even more precise by eliminating "dead time," a key limiting factor in the measurement process, thereby enabling the detection ...
Phys.org / New bioinformatics tools help identify pathogenic variants in the genome
Structural variants and so-called tandem repeats are individual differences in the human genome. They are increasingly linked to diseases, but analyzing and interpreting them poses challenges for researchers.
Phys.org / Could expanding the U.S. nuclear arsenal make Americans less safe?
A new report from the Brookings Institution presents evidence that increasing the size of the U.S. nuclear arsenal could make nuclear crises more likely. This raises an important challenge to arguments that the U.S. must ...
Phys.org / Nearly 50 'ghost galaxies' emerge around three hosts, challenging dwarf galaxy counts
Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been ...
Phys.org / Half-billion-year-old fossils rewrite the origin story of starfish
Scientists have discovered several 518-million-year-old fossils that reshape understanding of the origins of the animal group containing starfish. The fossils show that these animals ate using tentacles rather than passively ...
Phys.org / Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...
Phys.org / Luminescence dating pushes age of South Dakota's Mammoth Site back by more than 100,000 years
Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, ...
