A simple rule drives the evolution of useless complexity

A new study at the University of Chicago has shown that elaborate protein structures accumulate over deep time even when they serve no purpose, because a universal biochemical property and the genetic code force natural selection ...

The structure of master growth regulator

A team of Whitehead Institute scientists has for the first time revealed the molecular structure of a critical growth regulator bound to its partner proteins, creating a fine-grained view of how they interact to sense nutrient ...
