E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible.
Phylogenomics data place the enigmatic plankton in the middle of the algal family tree, despite their apparent lack of plastids—an organelle characteristic of all other algae.
A study employing CRISPR/Cas9 to explore the evolutionary beginnings of some giant viruses finds evidence their large genomes arose from gene duplications.
