Phys.org / Dynamic 'breathing' in nanopore structures can maximize efficiency of molecule separation and diffusion
Nanoporous material-based separation technology is vital in many applications because it can precisely distinguish between and separate nearly identical chemical or biochemical molecules.
Phys.org / A lipid switch that blocks anthrax from entering cells
Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before ...
Phys.org / Self-cleaning nanoscale sensor could transform personalized medicine
Imagine a smart bandage that could continuously monitor an infected wound, alerting doctors when bacteria spread or when treatment begins to work. That vision is one step closer to reality with new research from Virginia ...
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 / AI-powered camera system offers low-cost way to monitor bumblebees, potentially other insects
Researchers have developed a low-cost, semi-automated, AI-driven method that uses remote cameras to survey bumblebees and potentially other insects. The new tool could have important implications for efforts to conserve declining ...
Phys.org / AI models explain 17% of earnings-day stock moves, up from 5%
To explain the stock market's reaction to earnings results, investors and other market participants have used a standard tool for decades: the earnings surprise.
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 / 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 / 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 / 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 ...
