Was the addition of mitochondria a first step in the formation of complex cells or one of the last? A new study of bacteria tries to answer this contentious question in evolutionary biology.
Mitochondria appear to communicate and cooperate with one another, both within and between cells. Biologists are only just beginning to understand how and why.
In grafted plants, shrunken chloroplasts can jump between species by slipping through unexpected gateways in cell walls.
An unorthodox symbiotic theory about the origin of eukaryotes’ defining characteristic may soon be put to the test.
Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
Cells in symbiotic partnership, sometimes nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways.
The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
