A new study published in Physiological and Biochemical Zoology reveals how these snakes maximize their chances of hitting the target.
A Canadian/U.S. research team has reported a novel approach to stimulating recovery from chronic stress disorders. Details of the therapeutic model, which exploits the natural dynamics of the body's "fight or flight" system, are published January 23 in the open-access journal PLoS Computational Biology. In contrast to conventional time-invariant therapy, the researchers propose a well-directed therapeutic push delivered according to an optimal treatment schedule.
