Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons
Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...
Phys.org / Fossil footprints reveal body size and group dynamics of 1.4-million-year-old human relative
Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
Phys.org / AI finds tiny gene editor changes that reduce unintended DNA edits
Gene editing is a highly precise and powerful technology that allows scientists to insert, delete, modify or replace DNA bases in living organisms. It has a variety of uses, including correcting disease-causing mutations ...
Phys.org / Quantum neural networks get their first hardware test
Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with ...
Phys.org / Why the future of fashion might involve wearing live fungi
The idea of having living fungi cover your body might not be the most appealing thing in the world. But what if it was part of a clothing fabric that could change color, protect you from UV rays and even repair its own tears? ...
Phys.org / How flying together helps Andean condors save energy
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce ...
Phys.org / Astronomers identify one of the universe's rarest black hole events
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Phys.org / Hubble shows star formation in Andromeda galaxy is winding down
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
Phys.org / Kids who own cellphones have poorer reading comprehension scores than those who don't, researchers find
School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. ...
