Microbes have skins that react to the environment, much in the same way that our skin sweats when it is hot, or shivers when it is cold outside. Fossilized microbial skins can give us a glimpse of how the climate was in the deep geological past. By discovering the ‘missing link’ between such fossil skins and the skins of living bacteria, Diana Sahonero, a microbiologist at Royal Netherlands Institute for Sea Research (NIOZ), has greatly improved the accuracy of climate reconstructions and predictions.
