  摘要：Streptomyces are a genus of ubiquitous soil bacteria from which the majority of clinically utilized antibiotics derive(1). The production of these antibacterial molecules reflects the relentless competition Streptomyces engage in with other bacteria, including other Streptomyces species(1,2). Here we show that in addition to small-molecule antibiotics, Streptomyces produce and secrete antibacterial protein complexes that feature a large, degenerate repeat-containing polymorphic toxin protein. ...

  摘要：Climate campaigners and politicians rightly concentrate on the benefits of clean energy - but without more support for those who are adversely affected, the backlash will only grow.
• The sympathetic nervous system arose in the earliest vertebrates AI翻译
  作者：Ernsberger, Uwe; Rohrer, Hermann
  作者单位：Goethe University Frankfurt
  摘要：The sympathetic nervous system, which enables the fight-or-flight response, was thought to be present only in jawed vertebrates. Analysis of a jawless vertebrate suggests that this system might be a feature of all animals with a spine.
