Phys.org / US residents near small rivers face disproportionately high future flood risks
An international team, including Kumamoto University and its partner institutions, has found severe flood risks and high climate-adaptation costs for U.S. small rivers.
Phys.org / Plant-derived lignin could guide bone repair by forming bone-like minerals
A naturally abundant plant material best known for giving trees and crops their strength may one day help repair broken bones, according to a new study led by postdoctoral researcher Dr. Srinath Palakurthy and Professor Rivka ...
Dialog / AI-designed SARS-CoV-2 variants escape prevalent antibodies
While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate ...
Phys.org / Helical nanoparticles trigger cancer alarms and deliver gene therapy
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...
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 / 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 / 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 / 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 / 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 / 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 / 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. ...
