Physarum polycephalum

Single cell amoebae can remember, make decisions and anticipate change, urging researchers to redefine what we perceive as intelligence as soon as possible. For gardeners, they are usually a pest, for some hikers, a nice view, and for researchers, they are protists, a taxonomic group reserved for “everything we don’t really understand,” says Chris Reid of the University of Sydney.
