...gues at ORNL describe the bacterial community that thrives in what amounts to sulfuric acid. Their work set the stage for the latest development because it provided the first large-scale proteome dataset for a real-life microbial community with a limited number of members. Of particular interest to DOE is ...Looking for life on Jupiter's icy moon Europa

"Life thrives in ice, it doesn't mind at all," said Lipps, whose interest in single-celled organisms drew him to consider the possibility of life on other planets, which is likely to be more akin to bacteria than to humans.

...'s elemental defense. The new moth variety in fact thrives on plants containing highly toxic selenium levels and, in contrast to related varieties, was not deterred from either laying eggs or feeding on the plant. Furthermore, the researchers found that a selenium-tolerant wasp (Diadegma insulare) in turn pa...Two miles underground, strange bacteria are found thriving
