  • Hyenas cooperate to solve puzzles.
  • Back in February, I linked to a fascinating article about bacteria without cell walls. Here is a blog post on the research, which includes pictures. [Update: I have since learned that L-form bacteria have been known since the 1930s, and that it is only the method of reproduction that is news.]

Palaeontology and Archaeology:
