Phys.org / Stellar stream beyond Milky Way offers new tool to map dark matter
In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history ...
Phys.org / Europe's worst medieval flood highlights risk of successive extreme events
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
Phys.org / Quantum advantage reassessed: More realistic benchmarks for quantum algorithms
Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, ...
Phys.org / Mirage or miracle? JWST finds earliest known 'black hole star' at cosmic dawn
Little red dots have puzzled astronomers since their discovery in James Webb Space Telescope (JWST) data from the universe's deep past. Their "powering engines" might resemble a newly discovered phenomenon dubbed a "black ...
Phys.org / Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices
Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing ...
Phys.org / Graphene nanowrinkles could reshape electricity in future ultrathin devices
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity, a phenomenon in which a material generates an electric charge ...
Phys.org / Drug-carrying nanoparticles shrink venous malformations by 70% in mice
Venous malformations are abnormally shaped veins that develop when the cells lining blood vessels grow too fast when they aren't supposed to. Children can be born with them, and as the child grows, the venous malformations ...
Phys.org / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Phys.org / Space travel doesn't affect the strength of heart muscle cells, study finds
It's common to see images of astronauts on the International Space Station exercising, running on special treadmills and pedaling cycles designed for tight quarters.
Phys.org / Claim that science is becoming less disruptive challenged after years-long publication delay
A widely cited Nature cover article from 2023 claimed that scientific innovation has significantly declined in recent decades. This finding was based on a citation analysis of large sets of metadata concerning scientific ...
Phys.org / How drought is reshaping the spread of infectious diseases
From the American West to Europe, droughts are drying up rivers, fueling destructive fires and reshaping ecosystems. They are also changing the spread of infectious diseases, leading to surges in illnesses like cholera and ...
Phys.org / What happens to nanoparticles when they enter the bloodstream?
The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. ...
