摘要：The Yamnaya archaeological complex appeared around 3300 bc across the steppes north of the Black and Caspian Seas, and by 3000 bc it reached its maximal extent, ranging from Hungary in the west to Kazakhstan in the east. To localize Yamnaya origins among the preceding Eneolithic people, we assembled ancient DNA from 435 individuals, demonstrating three genetic clines. A Caucasus-lower Volga (CLV) cline suffused with Caucasus hunter-gatherer1 ancestry extended between a Caucasus Neolithic south...

摘要：Broadly neutralizing antibodies (bNAbs) show potential to prevent human immunodeficiency virus (HIV-1) infection in humans1. However, there are limited data on the antibody concentrations required to prevent infection. Clinical trials of bNAb prophylaxis have demonstrated partial efficacy2, but the sampling frequency typically does not allow precise timing of infection events and concurrent antibody levels. Here, using simian immunodeficiency virus (SIV) infection of rhesus macaques, we show t...

摘要：Quantum networks that distribute entanglement among remote nodes will unlock transformational technologies in quantum computing, communication and sensing1, 2, 3-4. However, state-of-the-art networks5, 6, 7, 8, 9, 10, 11, 12, 13-14 use only a single optically addressed qubit per node; this constrains both the quantum communication bandwidth and memory resources, greatly impeding scalability. Solid-state platforms15, 16, 17, 18, 19, 20, 21, 22, 23-24 provide a valuable resource for multiplexed ...

摘要：Intra-atomic orbital hybridization and interatomic bond formation are the two fundamental processes when real atoms are condensed to form matter1,2. Artificial atoms mimic real atoms by demonstrating discrete energy levels attributable to quantum confinement3, 4, 5, 6, 7-8. As such, they offer a solid-state analogue for simulating intra-atomic orbital hybridization and interatomic bond formation. Signatures of interatomic bond formation have been extensively observed in various artificial atom...

摘要：Extreme droughts generally decrease productivity in grassland ecosystems1, 2-3 with negative consequences for nature's contribution to people4, 5, 6-7. The extent to which this negative effect varies among grassland types and over time in response to multi-year extreme drought remains unclear. Here, using a coordinated distributed experiment that simulated four years of growing-season drought (around 66% rainfall reduction), we compared drought sensitivity within and among six representative g...
