  • Ovonic threshold switching between high-resistive and conductive states in chalcogenide alloys is crucial for phase change memories and selector elements, yet its voltage dependence on field polarity remains underexplored. Here, the authors elucidate this phenomenon using electrical measurements, numerical simulations based on Technology Computer Aided Design, and DFT calculations, proposing a Graded Band Gap model that enhances memory design by predicting programming window characteristics.

  • COVID-19 is a serious pandemic threat to public health, but insights on the pathophysiological and immunological conditions are only emerging. Here the authors use multi-color flow cytometry to characterize CD4+ and CD8+ T cells in peripheral blood from 39 COVID-19 patients in Italy to report altered T cell activation, function and polarization.

  • Tailoring the crystallization kinetics of materials is important for targeting applications. Here the authors observe a remarkable dependence of crystallization and vitrification kinetics and attribute it to systematic bonding changes for a class of materials between metallic and covalent bonding.

  • This paper reports the genome sequence of domesticated tomato, a major crop plant, and a draft sequence for its closest wild relative; comparative genomics reveal very little divergence between the two genomes but some important differences with the potato genome, another important food crop in the genus Solanum.
