• Blockbuster obesity drug leads to better health in people with HIV AI翻译
  作者：Lenharo, Mariana
  摘要：Semaglutide reduces weight and fat accumulation associated with the antiretroviral regimen that keeps HIV at bay.
• Editorial Expression of Concern: p63 and p73 are required for p53-dependent apoptosis in response to DNA damage (Expression of Concern of Vol 627, Pg E 10, 2024) (Publication with Expression of Concern. See vol. 627, 2024) AI翻译

• Complex motions emerge from robot interactions AI翻译
  作者：Huber, Sebastian D.; Huhtinen, Kukka-Emilia
  作者单位：Swiss Federal Institutes of Technology Domain; ETH Zurich
  摘要：An array of robots has been set up so that pushes between them produce movements that do not conform to the usual laws of motion. Fascinating behaviour emerges from these interactions: wave phenomena known as solitons.
• Did 'alien' debris hit Earth? Startling claim sparks row at scientific meeting AI翻译
  作者：Witze, Alexandra
  摘要：Astrophysicist Avi Loeb says that an interstellar meteor showered Earth with particles. At a planetary-science conference this week, researchers begged to differ.

  摘要：Topological whirls or 'textures' of spins such as magnetic skyrmions represent the smallest realizable emergent magnetic entities1-5. They hold considerable promise as robust, nanometre-scale, mobile bits for sustainable computing6-8. A longstanding roadblock to unleashing their potential is the absence of a device enabling deterministic electrical readout of individual spin textures9,10. Here we present the wafer-scale realization of a nanoscale chiral magnetic tunnel junction (MTJ) hosting a...
• Chatbot AI makes racist judgements on the basis of dialect AI翻译
  作者：Gibney, Elizabeth
  摘要：Some large language models harbour hidden biases that cannot be removed using standard methods.

  摘要：The generation of ultra-low-noise microwave and mmWave in miniaturized, chip-based platforms can transform communication, radar and sensing systems1-3. Optical frequency division that leverages optical references and optical frequency combs has emerged as a powerful technique to generate microwaves with superior spectral purity than any other approaches4-7. Here we demonstrate a miniaturized optical frequency division system that can potentially transfer the approach to a complementary metal-o...
