Buried Lake Vostok May Support a Thriving Ecosystem Two Miles Beneath the Surface of Antarctica
Lake Vostok, a body of water located about two miles beneath Antarctica's icy surface, may be home to a viable ecosystem in spite of intense cold, complete darkness, lack of nutrients, and possible volcanic activity. And what's more, new evidence uncovered from samples of organic material suggest that the lake's inhabitants could include complex life forms such as arthropods, mollusks, and even fish. A group of researchers at Bowling Green State University (BGSU) concluded in a new study published in the journal PLOS ONE that "although Lake Vostok is oligotrophic," or nutrient poor, "based on the metagenomic and metatranscriptomic results presented here, it is far from sterile."Read on...
The Oldest Life on Earth Still Dominates at This German Cold SpringDo you want to get a glimpse of the life that dominated Earth during prehistoric times without being menaced by hyper-intelligent raptors? A German cold spring with a unique environment can offer you a look back into our planet's past, to a time when simple life forms known as archaea made the rules. Granted, it's not exactly Jurassic Park. You'll need a high powered microscope just to see these prehistoric creatures, and they're not exactly as exciting to watch as a triceratops. Then again, they're also not going to try to murder and eat you, proving once again that life is a series of compromises leading inexorably to bitter disappointment. As if there were any doubt.Read on...
