Drs2 flips the phospholipid switch

Drs2 flips the phospholipid switch T he protein Drs2 flips phospholipids between membrane layers. Xu et al. identify which phospholipid the protein relocates to allow transport between the transGolgi network and the early endosome. Drs2 commutes from the trans-Golgi network (TGN) to the early endosome (EE) and then back again. Without Drs2, cells can’t ship proteins along this route. The molecu...

GUEST COMMENTARY Quorum Sensing “Flips” the Acetate Switch

The term “acetate switch” refers to the transition from acetate production (dissimilation) to acetate utilization (assimilation). Best studied with the enteric bacterium Escherichia coli, the acetate switch takes place as cells deplete their environment of acetate-producing (acetogenic) carbon sources, such as D-glucose or L-serine, and begin to scavenge for the previously produced and excreted...

Programmable resistive-switch nanowire transistor logic circuits.

Programmable logic arrays (PLA) constitute a promising architecture for developing increasingly complex and functional circuits through nanocomputers from nanoscale building blocks. Here we report a novel one-dimensional PLA element that incorporates resistive switch gate structures on a semiconductor nanowire and show that multiple elements can be integrated to realize functional PLAs. In our ...
