The micromammals.
In this editorial, Senior Editor Susan Forsburg examines the reasons to keep studying eukaryotic microbes like  S. pombe  and  S. cerevisiae —and other yeasts, algae, amoeba, and fungi—even as genetic and genomic technologies now allow manipulation and study of practically any organism. She explores the challenges and opportunities of working in these tiny organisms, pointing to the substantial biology their study has uncovered.
