These Organelles Have No Membranes
Michael Crabtree and Tim Nott | Dec 1, 2018 | 10+ min read
From making ribosomes to protecting the integrity of the genome, these membraneless compartments play important roles in the cell. Their behavior is rooted in basic physics.
Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.
