With DNA from just four cells, Danish researchers reveal how some of the world’s most abundant organisms play a key role in carbon cycling in the seabed.
Single-celled archaea are invisible to the naked eye, and even when using a microscope, great care must be taken to observe them. An international team of researchers led by the Center for Geomicrobiology, Aarhus University, has nevertheless succeeded in retrieving four archaeal cells from seabed mud and mapping the genome of each one.
