New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

Sitting in my campsite at Goblin Valley State Park, I saw an antelope ground squirrel standing erect on its back feet, which I found amusing. I soon found that this was a common posture evoked by ...
