Observing the hot 17 Mar 2008 The ever-interesting blog of Moselio Schachter, Small Things Considered has another post of thought-provoking microbes: hyperthermophiles. These wee beasties live at 90°C in anoxic conditions. I particularly liked the passing comment: Growth and division of these organisms was observed at 90°C under anoxic conditions using a dark-field light microscope (which takes quite a set-up). Um yes. I’m betting that was a Herculean effort! In particular this is interesting because there is a bias in identifying microbes that do not culture in ordinary lab conditions. These researchers are to be congratulated for going to such lengths. Ecology and Biodiversity Evolution General Science Species and systematics

It’s interesting in its own right, but also to show how cooperation can evolve… Read More
