Stammering speech, or stuttering, has traditionally been thought to be an indication of anxiety or stress. A large amount of evidence, however, has long supported the idea that it must have some genetic component. For instance, identical twins often both stutter, as do other family members.

The discovery was particularly interesting, because, previously, the gene had only been believed to be related to “general housekeeping” of the body, such as digestion. How could a gene that affects every cell of the body cause something so mechanical as stuttering? [Read more…]

It’s a disgusting way to live, but dung beetles do it … and thereby deserve their unenviable name. Males of the species seek out steaming piles of manure, descend on them, shape some of the smelly stuff into balls, and roll them away from chaos of the pile, hopefully attracting a mate along the way.
