Verne's 1877 book (also published as "Hector Servadac") was a bit fanciful, but it had an element of truth: life may have hitchhiked across the solar system. The proof may be found at the ends of the Earth. This week, American and Russian scientists are examining deep ice from the Antarctic and hoping to find clues that fungi, bacteria, and even diatoms could survive conditions in icy solar system bodies. This would help make the South Pole one of the first destinations for the growing field of astrobiology.

The scope of the enquiry was intended to cover active growth not survival through some form of encystment. A very warm thank you to all those who contributed to my search.

"We proved that the tubeworm larvae can live long enough for the underwater highways that run deep in the ocean to take them from one vent to another," said Donal Manahan, professor of biological sciences and dean of research in the USC College of Letters, Arts and Sciences. Manahan studies life in extreme conditions, although he does not view them as extreme.

The Domain Archaea wasn't recognized as a major domain of life until quite recently. Until the 20th century, most biologists considered all living things to be classifiable as either a plant or an animal. But in the 1950s and 1960s, most biologists came to the realization that this system failed to accomodate the fungi, protists, and bacteria. By the 1970s, a system of Five Kingdoms had come to be accepted as the model by which all living things could be classified. At a more fundamental level, a distinction was made between the prokaryotic bacteria and the four eukaryotic kingdoms (plants, animals, fungi, & protists). The distinction recognizes the common traits that eukaryotic organisms share, such as nuclei, cytoskeletons, and internal Read More Go to Site Life at High Temperatures Votes:0 Life at High Temperatures Life at High Temperatures by Thomas D.

Hydrogen sulfide is a naturally occurring compound. It smells like rotten eggs. If you walk out on the mud flats, you'll smell it. It occurs in many different environments. The interesting thing about hydrogen sulfide, biologically, is that it is a highly toxic molecule. It is toxic on the same level as cyanide. It is toxic because it binds to iron. There are two important iron atoms in biological systems. One is at the center of the hemoglobin molecule. So, typically in the presence of hydrogen sulfide oxygen transport by hemoglobin is blocked and can no longer go on. The second and more ubiquitous proble Read More Go to Site Microbes: What They Do and How Antibiotics Change Them by Maura J.

Photograph of a starry skate and an asteroid starfish (center left) from Fram Strait. Deep, under perpetual ice cover, with reduced photosynthesis and thus little organic matter coming from above, the sea floor of the central Arctic Ocean is a marine desert, its life more sparse than in other ocean basins.

Onstott got a close-up peek at hell last year when he descended into the steamy bowels of the planet. With his shirt drenched from the 100 percent humidity, the Princeton University geologist slogged through the deepest gold mine in South Africa, where the temperature of the rock reaches 60?C (140?F) and sunlight is but a distant dream, some 3.5 kilometers up. After an hour of hiking through the passages, Onstott reached a recently blasted section of tunnel and took a hammer to the wall, knocking loose nuggets of rock that had spent the last 3 billion years locked underground. These chunks, he suspected, were alive inside. A little over 10 years ago, such an idea would have seemed pure folly.

It's remote, it's cold, and the very name carries unpleasant memories of prison camps. But it's also an ideal place to look for life-forms that have learned survival tricks that might be in use on the permafrost and polar caps of Mars, Europa, Callisto and other icy moons of the solar system. Right : Hoover displays growing moss that remained alive yet dormant while frozen for 40,000 years in the permafrost of the Kolyma Lowlands of northeastern Siberia.
