Open the doors to the public to promote support

The author recently wrote about the animal use/animal rights battle and the increasing violence on the part of animal rights activists. He recounts being an outsider learning about the field and the issues at hand, lending insight into how the LAS field might better communicate with the communicators.     

RNA kink turns to the left and to the right

A helix-loop-helix within the group I intron has most of the canonical sequence elements of a kink turn (K-turn), yet it bends in the opposite direction. The reverse K-turn kinks toward the major rather than the minor grooves of the flanking helices. This suggests that there are two distinct subclasses of tertiary structures that a K-turn secondary structure can adopt. The final structure may be specified by external factors, such as protein binding or the tertiary structural context, rather than the intrinsic conformation of the RNA.
