Anomalous Metamagnetism In The Low Carrier Density Kondo Lattice YbRh3Si7

There’s an oddball in most families, but Rice University physicist Emilia Morosan has discovered an entire clan of eccentric compounds that could help explain the mysterious electronic and magnetic workings of other quantum materials engineers are eying for next-generation computers and electronics. Morosan and 30 co-authors describe the first family member—a “semimetallic Kondo lattice” made … Read more

Observation Of Brillouin Optomechanical Strong Coupling With An 11 GHz Mechanical Mode

Light and high-frequency acoustic sound waves in a tiny glass structure can strongly couple to one another and perform a dance in step. A team of researchers from Imperial College London, the University of Oxford, and the National Physical Laboratory have experimentally achieved a long-standing goal to demonstrate the so-called “strong-coupling regime” between light and … Read more

Awareness Of What Is Learned As A Characteristic Of Hippocampus-Dependent Memory

Two Veterans Affairs researchers have explored how memory is tied to the hippocampus, with findings that will expand scientists’ understanding of how memory works. Drs. Christine N. Smith and Larry R. Squire, both with the VA San Diego Healthcare System and the University of California, San Diego, found that declarative memory—recalling facts and events—depends on … Read more

Age-Related Loss of Innate Immune Antimicrobial Function of Dermal Fat Is Mediated by Transforming Growth Factor Beta

Dermal fibroblasts are specialized cells deep in the skin that generate connective tissue and help the skin recover from injury. Some fibroblasts have the ability to convert into fat cells that reside under the dermis, giving the skin a plump, youthful look and producing a peptide that plays a critical role in fighting infections. In … Read more
