  摘要：The basal plane of graphene can function as a selective barrier that is permeable to protons 1,2 but impermeable to all ions 3,4 and gases 5,6 , stimulating its use in applications such as membranes 1,2,7,8 , catalysis 9,10 and isotope separation 11,12 . Protons can chemically adsorb on graphene and hydrogenate it 13,14 , inducing a conductor-insulator transition that has been explored intensively in graphene electronic devices 13-17 . However, both processes face energy barriers 1,12,18 and v...

  摘要：DNA from organelles called mitochondria is not inherited from the father. But mitochondrial RNAs that sense paternal diet and mitochondrial quality are delivered from sperm to egg, affecting offspring metabolism.

  摘要：Kainate receptors, a subclass of ionotropic glutamate receptors, are tetrameric ligand-gated ion channels that mediate excitatory neurotransmission 1-4 . Kainate receptors modulate neuronal circuits and synaptic plasticity during the development and function of the central nervous system and are implicated in various neurological and psychiatric diseases, including epilepsy, depression, schizophrenia, anxiety and autism 5-11 . Although structures of kainate receptor domains and subunit assembl...

  摘要：Angiogenin, an RNase-A-family protein, promotes angiogenesis and has been implicated in cancer, neurodegenerative diseases and epigenetic inheritance1-10. After activation during cellular stress, angiogenin cleaves tRNAs at the anticodon loop, resulting in translation repression11-15. However, the catalytic activity of isolated angiogenin is very low, and the mechanisms of the enzyme activation and tRNA specificity have remained a puzzle3,16-23. Here we identify these mechanisms using biochemi...
• Language is primarily a tool for communication rather than thought AI翻译

  摘要：Language is a defining characteristic of our species, but the function, or functions, that it serves has been debated for centuries. Here we bring recent evidence from neuroscience and allied disciplines to argue that in modern humans, language is a tool for communication, contrary to a prominent view that we use language for thinking. We begin by introducing the brain network that supports linguistic ability in humans. We then review evidence for a double dissociation between language and tho...
