Realization of a spin glass in a two-dimensional van der Waals material

2 weeks ago
Recent advances in van der Waals materials have sparked renewed interest in the impact of dimensionality on magnetic phase transitions. Although ordered magnetic phases have been demonstrated to survive in the two-dimensional (2D) limit, the quest for a spin glass with quenched magnetic disorder in lower dimensions has proven elusive. Here, we provide evidence of a spin glass emerging from randomly distributed Fe atoms in Fe(3)GeTe(2) (FGT). ac magnetic susceptibility displays a strong frequency...

A conserved regulatory architecture stabilizes cellular senescence across distinct triggers in human fibroblasts

2 weeks ago
Cellular senescence arises through replicative exhaustion or acute stress, yet whether these distinct triggers share a reproducible transcriptional organization has remained unresolved. Seven public human fibroblast RNA-seq datasets were integrated across both trigger types, moving from differential expression through Gene Ontology and Reactome enrichment to protein-protein interaction network embedding within a single harmonized framework. Both triggers converged on concordant repression of...

Scientists find a way to stop dangerous belly fat as we age

2 weeks ago
Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a testosterone gel combined with exercise helped prevent the usual rise in dangerous visceral fat. The result could point to a powerful new strategy for improving recovery and long-term health.
