Big brains are all in the genes

Scientists have moved a step closer to understanding genetic changes that permitted humans and other mammals to develop such big brains.

Selection drives functional evolution of large enzyme families

Researchers at UmeƄ University, together with researchers at the Institute of Botany, Chinese Academy of Sciences, show in a new study how natural selection drives functional evolution of a large protein family in conifer ...

Plants cut the mustard for basic discoveries in metabolism

You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, including humans, ...

The determining factors of cell shape examined

A European team is investigating the role of the bacterial cell wall and the cytoskeleton in mediating cell shape. Results are expected to have broader implications for cell biology.

Small change makes a big difference for ion channels

Using a high-resolution single-molecule study technique, University of Illinois researchers have seen the very subtle differences between two branches of an important family of neurotransmitter-gated ion channels.
