In this computer simulation of a self-replicating structure, the pink square represents the signal to degrade the connection between the “parent” structure (left) and its “offspring” (right). This ...

We often see the results of evolution, but not the process directly. Now, scientists have been treated to front row seats of evolution unfolding in real time, as two similar lizard species encounter ...

Evolution is the central unifying theme of biology. Yet today, more than a century and a half after Charles Darwin proposed the idea of evolution through natural selection, the topic is often ...

Surprising animal behaviors, from birds to amphibians, are revealing deep biological processes. Scientists are uncovering how viruses manipulate cells, how the immune system balances defense, and how ...

EPFL researchers have developed a light-based method that can produce proteins that switch states, respond to signals, and even compute, using light and the cell cycle.

A molecular biologist may have found a new 'rule of biology.' The rule challenges long-held notions that most living organisms prefer stability over instability because stability requires less energy ...
