If there was ancient microbial life on Mars, it might have left similar traces in Martian rocks, scientists say. April 20, 2005 WASHINGTON - A "weird" community of microbes living in a hot, acidic geyser in Wyoming's Yellowstone Park may help scientists know what to look for in seeking life on Mars and elsewhere in space, researchers said Wednesday. They found the new species of algae and bacteria living in a green-colored layer of sandstone in Yellowstone's Norris Geyser Basin. It was not a place where one would normally expect to find life thriving, said biologist Norman Pace of the University of Colorado at Boulder's Center for Astrobiology. "The pores in the rocks where these creatures live has a pH value of one, which dissolves nails," Pace said in a statement. "This is another example that life can be robust in an environment most humans view as inhospitable."

One asteroid from Mars found in Antarctica is being studied extensively to see if it carries fossilized remnants of tiny bacteria. "Remnants of these communities could serve as 'biosignatures' and provide important clues about ancient life associated with geothermal environments on Earth or elsewhere in the solar system," the researchers wrote in their report, published in the journal Nature. Rich in acid, metals and silicates The waters of Norris Geyser Basin, one of the hottest in the world, are rich in sulfuric acid, metals and silicates. Similar kinds of geothermal environments may once have existed on Mars. Robotic rovers are searching the planet's surface for evidence of them. "This is the first description of these microbial communities, which may be a good diagnostic indicator of past life on Mars because of their potential for fossil preservation," said Jeffrey Walker, who helped write the study. "The prevalence of this type of microbial life in Yellowstone means that Martian rocks associated with former hydrothermal systems may be the best hope for finding evidence of past life there," he said. 'Eureka' moment Walker said he found the new microbe community in 2003 after breaking apart a chunk of sandstonelike rock. "I immediately noticed a distinctive green band just beneath the surface," he said. "It was one of those 'eureka' moments." http://msnbcmedia.msn.com/j/msnbc/Components/Photos/050420/050420_yellowstone_life_bcol.standard.jpg The distinctive green band was found just beneath the surface of sandstone from Norris Geyser Basin. Genetic analysis determined the green band was caused by a new species of photosynthetic Cyanidium algae. Living among them were a new species of Mycobacterium, a group of microbes best known for causing human illnesses such as tuberculosis and leprosy, Walker said. Other species of bacteria also living in the rock, and only a few were the "extremophile" species usually found in such environments, the researchers said. Pace described the new life forms as "pretty weird." "It may well be a new type of lichenlike symbiosis," said Pace, who won a MacArthur Fellowship, or "genius grant," in 2001. "It resembles a lichen, but instead of being comprised of a symbiosis between a fungus and an alga, it seems to be an association of the Mycobacterium with an alga."

Niemand? Er is trouwens laatst ook een nieuw element ondekt: Scientists discover new element Reuters (http://www.dullmen.com/governmentium.htm) - September 26, 2005 A major research institution (MRI) has recently announced the discovery of the heaviest chemical element yet known to science. The new element has been tentatively named Governmentium. Governmentium has 1 neutron, 12 assistant neutrons, 75 deputy neutrons, and 224 assistant deputy neutrons, giving it an atomic mass of 312. These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons. Since governmentium has no electrons, it is inert. However, it can be detected as it impedes every reaction with which it comes into contact. A minute amount of governmentium causes one reaction to take over four days to complete when it would normally take less than a second. Governmentium has a normal half-life of three years; it does not decay, but instead undergoes a reorganization in which a portion of the assistant neutrons and deputy neutrons exchange places. In fact, governmentium's mass will actually increase over time, since each reorganization will cause some morons to become neutrons, forming isodopes. This characteristic of moron-promotion leads some scientists to speculate that governmentium is formed whenever morons reach a certain quantity in concentration. This hypothetical quantity is referred to as Critical Morass. :hihi:

[schaapje14]

Hartstikke goed dit soort ontdekkingen, de mens komt steeds verder in de ontrafeling en zoektocht naar het ontstaan van leven.

Je bent toch wel iets,mens toch en dat mag je toch niet iets noemen.:D Ik ben gewoon ik. Van het idee van een oppergod met belachelijk veel regels moet ik lachen :hihi: De heilige geschriften zijn niet anders dan de wetten die we nu hier kennen. Alleen toen had je geen centrale overheid. Ik zal vast onder het kopje atheist vallen maar zo voel ik me niet ofzo.

Ach er zijn nog zoveel dingen op aarde te ontdekken. By Patricia Reaney LONDON (Reuters) - Australian scientists said on Tuesday they have discovered more remains of hobbit-sized humans which belong to a previously unknown species that lived at the end of the last Ice Age. Professor Mike Morwood, of the University of New England, in Armidale, Australia, stunned the science world last year when he and his team announced the discovery of 18,000-year-old remains of a new human species called Homo floresiensis. The partial skeleton discovered in a limestone cave on the remote Indonesian island of Flores in 2003 was of a tiny adult hominid, or early human, only one meter (3 feet tall), that would have walked upright and had a chimpanzee-sized brain. Morwood and his team said it represented a unique species of early humans that evolved to a naturally small size because of environmental conditions and the isolation of the island, which was also home to exotic creatures such as miniature elephants and Komodo dragons. But critics suggested the small hominid was not a new species and was more likely a pygmy human or a creature that suffered from a form of microcephaly, a condition that causes an unusually small brain. "The finds further demonstrate ...(it) is not just an aberrant or pathological individual but is representative of a long-term population," Morwood and his team said in a report in the science journal Nature.

Dan nog even dit. George Deutsch/Erica Hupp Headquarters, Washington (Phone: 202/358-1324/1237) October 6, 2005 RELEASE: 05-388 NASA Scientists Confirm Toxic Seas During Earth's Evolution NASA exobiology researchers confirmed Earth's oceans were once rich in sulfides that would prevent advanced life forms, such as fish and mammals, from thriving. The research was funded in part by NASA's exobiology program. A team of scientists from the Massachusetts Institute of Technology and Harvard University, working with colleagues from Australia and the United Kingdom, analyzed the fossilized remains of photosynthetic pigments preserved in 1.6 billion-year-old rocks from the McArthur Basin in Northern Australia. They found evidence of photosynthetic bacteria that require sulfides and sunlight to live. Known as purple and green sulfur bacteria because of their respective pigment colorations, these single-celled microbes can only live in environments where they simultaneously have access to sulfides and sunlight. The researchers also found very low amounts of the fossilized remains of algae and oxygen-producing cyanobacteria. The relative scarcity of these organisms is due to poisoning by large amounts of sulfide. "This work suggests Earth's oceans may have been hostile to animal and plant life until relatively recently," said Dr. Carl Pilcher, NASA's senior scientist for astrobiology. "If so, this would have profound implications for the evolution of modern life." "The discovery of the fossilized pigments of purple sulfur bacteria is totally new and unexpected. Because they need fairly high intensity sunlight, it means the pink bacteria, along with their essential source of sulfide, close to the surface, perhaps as close as 20 to 40 meters," said Roger Summons, Massachusetts Institute of Technology professor of geobiology. "The sulfide would have come from bacteria that reduces sulfate carried into the oceans by the weathering of rocks." "The McArthur Basin rocks were deposited over a very large area and over many millions of years, so it's likely they formed under water that was intermittently connected to or actually part of an ocean. In turn, this implies the ocean had an abundant and continuous supply of hydrogen sulfide and must have been quite toxic to any oxygen-breathing organisms," said team member Jochen Brocks. "In fact, for seven-eighths of Earth's 4.5 billion-year history, there was probably little oxygen in the oceans and certainly not enough to support oxygen-breathing marine animals." This research continued the efforts of NASA and partner institutions to understand the early history of the Earth. Research results were published in the Oct. 6, 2005, edition of Nature magazine. The research was conducted by a team working in Summons' laboratory. Team members include Jochen Brocks, formerly of Harvard and now at Australian National University; Gordon Love, Massachusetts Institute of Technology; Stephen Bowden, University of Aberdeen, Scotland; Graham Logan, Geoscience Australia; and Andrew Knoll, Harvard.

Dat is nou de tragiek van de mensheid: Miljarden Dollars uitgeven om bewonderend te staren naar een onbenullige, primitieve, vast schadelijke, onbekende primitieve bacteriesoort op Mars, terwijl we op onze Aarde miljoenen hogere diersoorten uitroeien door ontbossing (overbevolking), roofvisserij en monocultuur ... :jammer:
