• What happens when climate change and the mental-health crisis collide? AI翻译
  作者：[Anonymous]
  摘要：The warming planet is worsening mental illness and distress. Researchers need to work out the scale of the problem and how those who need assistance can be helped.

  摘要：Humans and other social animals are highly adept at learning by observing how others interact with the environment, especially when identifying potential sources of danger. In mice, a specific brain region acts as an information-processing hub that distinguishes between observed and directly experienced fear, and signals different behavioural responses accordingly.
• After the genocide: what scientists are learning from Rwanda AI翻译
  作者：Gaind, Nisha
  摘要：Thirty years after the genocide against the Tutsi in Rwanda, Nature met with researchers who are gaining insights that could help to prevent other atrocities and enable healing.

  摘要：Heteroarenes are ubiquitous motifs in bioactive molecules, conferring favourable physical properties when compared to their arene counterparts(1-3). In particular, semisaturated heteroarenes possess attractive solubility properties and a higher fraction of sp(3) carbons, which can improve binding affinity and specificity. However, these desirable structures remain rare owing to limitations in current synthetic methods(4-6). Indeed, semisaturated heterocycles are laboriously prepared by means o...
• Automated model building and protein identification in cryo-EM maps AI翻译

  摘要：Interpreting electron cryo-microscopy (cryo-EM) maps with atomic models requires high levels of expertise and labour-intensive manual intervention in three-dimensional computer graphics programs1,2. Here we present ModelAngelo, a machine-learning approach for automated atomic model building in cryo-EM maps. By combining information from the cryo-EM map with information from protein sequence and structure in a single graph neural network, ModelAngelo builds atomic models for proteins that are o...

  摘要：Life at the cutting edge.
• JOURNAL EDITORS ARE RESIGNING EN MASSE: WHAT DO THESE GROUP EXITS ACHIEVE? AI翻译
  作者：Sanderson, Katharine
  摘要：Editorial rebellions seem to be on the rise, as researchers seek more control over scholarly communication.

  摘要：Perovskite solar cells (PSCs) are among the most promising photovoltaic technologies owing to their exceptional optoelectronic properties 1,2 . However, the lower efficiency, poor stability and reproducibility issues of large-area PSCs compared with laboratory-scale PSCs are notable drawbacks that hinder their commercialization 3 . Here we report a synergistic dopant-additive combination strategy using methylammonium chloride (MACl) as the dopant and a Lewis-basic ionic-liquid additive, 1,3-bi...
