Phys.org / Unusual nonlinear thermoelectric effect appears in chiral tellurium, confirming theoretical predictions
An unusual thermoelectric effect has been observed in the semiconductor tellurium by RIKEN physicists for the first time. This demonstration points to the potential of similar materials to be used in applications such as ...
Phys.org / Uncovering the link between epigenetic modifications and chromatin structure
Certain epigenetic modifications can directly control how genetic material is packed in the nucleus, RIKEN researchers have shown. This has important implications for our understanding of how genes are expressed in different ...
Phys.org / Cell movement in the embryo: Zebrafish study shows that without keratin, nothing moves
Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together ...
Phys.org / Flint reveals changes in human mobility in the southern Pyrenees during the Upper Paleolithic
Analysis of more than 3,000 lithic artifacts from the Cova Gran de Santa Linya site (Les Avellanes-Santa Linya, Lleida) shows that anatomically modern human communities occupying the southern Pyrenees during the Upper Paleolithic ...
Phys.org / When noisy decision-making becomes a strategic advantage
A new study shows that apparently erratic or "sloppy" behavior in strategic situations is not necessarily a mistake. Under certain conditions, being less sensitive to one's own gains can become a long-term advantage.
Phys.org / AI-designed miniproteins switch key cell receptors on and off
G protein-coupled receptors, or GPCRs, sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies—from the ability ...
Phys.org / Piezoelectric effect in diamond membranes challenges century-old scientific dogma
A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline diamond membranes. This pioneering discovery challenges a century-long scientific dogma that diamonds ...
Phys.org / Researchers develop AI model that maps how genes work together in human cells
Scientists at the Icahn School of Medicine at Mount Sinai have created a new artificial intelligence (AI) model that helps reveal how genes function together inside human cells, offering a powerful new way to understand biology ...
Phys.org / Ice core discovery finds volcanic eruptions could cause greater global disruption than previously thought
New research from the University of St Andrews has precisely dated an eruption from Newberry Volcano and discovered that its ash spread more than 5,000 km across the globe, far further than previously thought for an eruption ...
Phys.org / Do you know how cynical your friends are?
New research from Michigan State University finds that people often project their own levels of cynicism—the belief that people are only interested in themselves and aren't sincere—onto their friends and consistently underestimate ...
Phys.org / Is organic farming the solution to enhance natural drought resilience in crops?
A study led by researchers from the Department of Microbiology at the University of Malaga has revealed how organic farming—using natural substances and processes and avoiding the use of synthetic chemicals—can, in the long ...
Phys.org / Developing seed atlas uncovers active genes tied to crop resilience and nutrition
Seeds like wheat, rice, and corn are at the center of the global food supply and provide most of the daily calories consumed worldwide. But despite their importance, scientists still do not fully understand many of the basic ...
