How cells correct errors under time pressure

How does a cell balance risk and speed when dividing? EPFL scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently.

New insight into the possible origins of life

Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity, following Darwinian evolution. This has provided the first empirical ...

New insights revealed in the evolution of community-level heredity

What would happen if a selection experiment was performed on thousands of communities of microbes based on some community-level function? Researchers from ESPCI Paris-PSL, College de France, and ENS-PSL used a theoretical ...

The spark that created life

Evolution by Darwinian natural selection is immensely powerful—both in nature and within laboratories. Using 'laboratory evolution', we can take an enzyme which combines random mutations and functional selection, and improve ...

Model offers insight into how life continues to evolve

(Phys.org)—One of the most puzzling things about evolution is that, even after 4 billion years, it hasn't stopped. Instead of culminating in a single best adapted species, today the Earth contains an estimated 8.7 million ...
