Scientists have been studying adaptations a bacteria that lives near hydrothermal vents on the sea floor, and how it survives hold and cold fluctuations.
Why this matters: When most people hear bacteria, they think food poisoning or, in extreme cases, Black Death. But the bacteria that make humans sick are just a tiny, tiny proportion of all the bacteria out there. There are bacteria all over, and they can survive under the most adverse conditions (one reason scientists apparently hold out hope for life on Mars). These particular bacteria hang out next to geysers on the sea floor; conditions are harsh and constantly changing. So scientists are interested in how they can survive. (It's not mentioned in the article, but sequencing this genome must have been an impressive feat; very few bacteria can be grown in lab cultures, and bacteria that are from extreme environments can be especially challenging.)
