Howard Hughes Medical Institute (HHMI) scientists have created a portrait of a DNA-snipping protein called Cas9 that reveals how the enzyme reshapes itself when it associates with an RNA molecule, creating a channel that lets it find and cleave its DNA target. The protein-RNA complex is a key component of a primitive bacterial immune system called CRISPR, and is also being used by researchers to cut specific DNA sequences in the laboratory for genome editing applications.

Frog Sound Samples and Tree Frog Macro Photography
Here is a small tribute of electronic media to our little green friends. First, we have some sound samples packs. The first is of a plethora of frogs going through random rhythms. This was sampled in the late summer of 2005. The second sample pack is processed one hits from the first pack.
