Evidence for a largely unexplored radiation of squamates (lizards, snakes, and amphisbaenians) in the Middle to Late Jurassic is revealed by analyses of morphospace expansion, disparity, and evolutionary rates.
Benchmark simulations show that the VEXAT muscle model is more accurate than a Hill-type muscle model at mimicking the response of biological muscle to length changes great and small.

Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.

A digital flesh model of the sail-backed dinosaur Spinosaurus was tested and performed very poorly in water, favoring the view of this dinosaur as a two-legged, wading ambush predator of large fish in shallow waterways and not an aquatic dinosaur.

This sesquiterpene hormone likely acted as a morphogenesis-to-differentiation switch in archaic embryos before it evolved its postembryonic function as the status quo regulator of insect metamorphosis.
A computational model shows that preparation arises as an optimal control strategy in input-driven recurrent neural networks performing a delayed-reaching task.
Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.
A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.
Stride-related modulated firing by neurons of the cerebellar nuclei is required for smooth execution of practiced locomotion and persists more easily with synchronous than asynchronous Purkinje-mediated inhibition.
