Nature, Published online: 17 July 2019; doi:10.1038/s41586-019-1393-yBy varying the vertical displacement field in a trilayer graphene and hexagonal boron nitride moiré superlattice, transitions can be observed from the superconducting phase to Mott insulator and metallic (...)

A calmodulin-gated calcium channel links pathogen patterns to plant immunity

mercredi 17 juillet 2019 par Wang Tian, Congcong Hou, Zhijie Ren, Chao Wang, Fugeng Zhao, Douglas Dahlbeck, Songping Hu, Liying Zhang, Qi Niu, Legong Li, Brian J. Staskawicz, Sheng Luan
Nature, Published online: 17 July 2019; doi:10.1038/s41586-019-1413-yThe cyclic nucleotide-gated channel proteins CNGC2 and CNGC4 form a calcium channel in Arabidopsis; this channel is blocked by calmodulin in the resting state but is phosphorylated and activated upon pathogen attack, (...)

Nature, Published online: 17 July 2019; doi:10.1038/s41586-019-1349-2Correction of oddities in the historical record of sea surface temperatures reveals that some basin-wide climate variations were an artefact of systematic biases that stem, in part, from Japanese records being truncated to (...)

Corrections to ocean-temperature record resolve puzzling regional differences

mercredi 17 juillet 2019 par Zeke Hausfather
Nature, Published online: 17 July 2019; doi:10.1038/d41586-019-02147-wAn analysis of the record of sea surface temperature reveals that some climate variations that are thought to have occurred in the North Atlantic and the North Pacific oceans are an artefact of changes in measurement (...)
