Scientists studying microbes from some of the saltiest lakes in Antarctica have discovered a new way the microbes can share DNA that could help them grow and survive. The research, based on 18 months of water sampling in remote Antarctic locations, could throw light on the evolutionary history of viruses. The team discovered some of the microbes contained small molecules of DNA called plasmids.

Advanced technologies has been used to illuminate the connectivity pattern of chandelier cells, a distinctive kind of inhibitory cell type in the mammalian brain. Scientists reveal for the first time how this candelabra-shaped cell interacts in a highly selective way with hundreds of excitatory cells in its neighborhood, receiving information from some, imparting information to others.
