  摘要：Developing an ultrafast and energy-efficient nonvolatile switching device may pose a strong impact on emerging computing architectures. However, processing speed has plateaued in the nanosecond regime, as further acceleration demands excessively large write power. We demonstrate ultralow power in picosecond switching using heterostructures of the antiferromagnet Mn3Sn and heavy metal tantalum, which exhibit spin-orbit torque switching by electrical pulses as short as 40 picoseconds. Power cons...

  摘要：Indole is widely present in pharmaceuticals and natural products. In this work, we report an intramolecular skeletal editing reaction of tryptamine derivatives enabled by photoreaction of a pendant amide that simultaneously achieves regioselective single-carbon replacement and substitution at the C2 position of indoles. This strategy facilitates deuteration, alkylation, arylation, and acylation at the indole C2 position while also enabling the incorporation of 13C-labeled carbon into the scaff...

• Wildlife trade drives animal-to-human pathogen transmission over 40 years AI翻译

  摘要：The wildlife trade affects a quarter of terrestrial vertebrates and creates opportunities for cross-species pathogen transmission, but its precise role in shaping animal-human pathogen exchange remains unclear. In our analysis of 40 years of global wildlife trade data, we show that traded mammals are 1.5-fold as likely to share pathogens with humans as nontraded mammals, and that illegal and live-animal trade further exacerbate pathogen sharing. Time spent in trade predicts the number of zoono...
