The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4. The hardness of a material normally is set …

A computer scientist has developed an AI-ready architecture that is twice as powerful as comparable in-memory computing approaches. The researcher applies a new computational paradigm using special circuits known as ferroelectric field effect transistors (FeFETs). Within a few years, this could prove useful for generative AI, deep learning algorithms and robotic applications. A computer scientist …
PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the endocrine system. Researchers have now introduced a new method for an economical, easy-to-use …
How fast does a droplet flow along a fiber? It depends on the diameter of the fiber… and also on its substructure! These are the findings of a study conducted by researchers who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet. How fast does a droplet flow along a fiber? …
Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can …

Primatologists are using genetic analysis to determine the geographic origin of ancient mummified baboons found in Egypt. The team finds evidence that the two legendary trading regions of Punt and Adulis may have been the same place separated by a thousand years of history. Primatologists are using genetic analysis to determine the geographic origin of …

NASA’s InSight mission to Mars helped scientists map out Mars’ internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars’ metallic core …
