  摘要：Controlling the localization of mobile charges in solids enables the discovery of correlated physical phenomena, but applying it for the development of next-generation electronics requires achieving such control under practical conditions. In this study, we report room-temperature, switchable charge localization in high-quality bilayer transistors that comprise a monolayer of molecular crystal on top of a monolayer semiconductor. By using an ion gate, we selectively populated either localized ...

  摘要：Two-dimensional (2D) transition-metal dichalcogenide (TMDC) semiconductors are promising materials for beyond-silicon electronics, but the growth of single-crystalline TMDCs has been limited to small wafer sizes in laboratory settings. We report the epitaxy of 150-millimeter single-crystalline TMDC wafers on lanthanum-passivated c-plane sapphire. The single atomic layer of lanthanum reduces the surface symmetry and increases the energy difference between antiparallel domains by as much as 200 ...

  摘要：It has long been debated whether non-avian dinosaurs went extinct abruptly or gradually at the end-Cretaceous (66 million years ago), because their fossil record at this time is mostly limited to northern North America. We constrain a dinosaur-rich unit to the south, the Naashoibito Member in New Mexico, to the very latest Cretaceous (similar to 66.4 to 66.0 million years), preserving some of the last-known non-avian dinosaurs. Ecological modeling shows that North American terrestrial vertebra...
• Escherichia coli with a 57-codon genetic code AI翻译

  摘要：The near-universal genetic code uses 64 codons to encode the 20 canonical amino acids and protein synthesis. Here, we designed and generated Escherichia coli with a 4-megabase synthetic genome in which we replaced known occurrences of six sense codons and a stop codon with synonymous codons. The resulting organism, Syn57, uses 55 codons to encode the 20 canonical amino acids.

  摘要：The circadian clock maintains synchrony between biological processes and light/dark cycles by integrating environmental cues. How the clock adapts to seasonal variations in the environment is incompletely understood. We found that a high-fat diet increased phosphorylation of the clock protein PERIOD2 (PER2) on serine 662 (S662), which was necessary and sufficient for regulating phase shifting of daily locomotor activity to entrain to seasonal light cycles. PER2-S662 phosphorylation correlated ...
