  摘要：The aza Paterno-Buchi reaction is a [2+2]-cycloaddition reaction between imines and alkenes that produces azetidines, four-membered nitrogen-containing heterocycles. Currently, successful examples rely primarily on either intramolecular variants or cyclic imine equivalents. To unlock the full synthetic potential of aza Paterno-Buchi reactions, it is essential to extend the reaction to acyclic imine equivalents. Here, we report that matching of the frontier molecular orbital energies of alkenes...

  摘要：Most insects, including human-targeting mosquitoes, detect odors through odorant-activated ion channel complexes consisting of a divergent odorant-binding subunit (OR) and a conserved co-receptor subunit (Orco). As a basis for understanding how odorants activate these heteromeric receptors, we report here cryo-electron microscopy structures of two different heteromeric odorant receptor complexes containing ORs from disease-vector mosquitos Aedes aegypti or Anopheles gambiae. These structures r...

  摘要：Jonathan Haidt's new book, The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness, is a hot seller that makes the case that smartphones and social media are largely responsible for the current mental health crisis among young people and that restricting their use below certain ages (14 for smartphones and 16 for social media) can have a positive effect on reversing or slowing the problem. A social psychologist at New York University Stern School of...
