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.

Scientists used light to evolve proteins that can switch, sense, and even “compute” inside living cells. Evolution is one of ...

All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to ...

A new platform combines rational protein design with continuous evolution to discover functional molecules more efficiently. In medicine and biotechnology, the ability to evolve proteins with new or ...

Humans don’t have a defined mating season like deer or wolves. Here’s how evolution blended biology, culture and social life into year-round intimacy.

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 ...

Human biology is the study of all aspects of the human organism including evolution, genetics, ecology, anatomy and physiology, development, anthropology, and nutrition, among others. A deep ...

"Why and how did life become so diverse? This has been a central problem in biology. Experimen-tal Evolution and the Nature of Biodiversity explores how diversity evolves in microbial popula-tions ...

Most bacteria replicate quickly. For example, Escherichia coli double their number in just 20 minutes. If the bacteria are infectious human pathogens, such rapid replication can be problematic. But ...
