Why four-legged animals are better sprinters

Scientists have studied the characteristics determining the maximum running speed in animals. The model they developed explains why humans cannot keep up with the fastest sprinters in the animal kingdom. Based on these calculations, the giant spider Sh…

Reverse optogenetic tool developed

A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers. They used an opsin — a protein that occurs in the brain and eyes — from zebrafish and introduced it into the brain of mice. Unlike other optogen…
