    Journal of Cosmology ^ | March 4, 2011 | Richard B. Hoover, Ph.D
    Dr. Hoover has discovered evidence of microfossils similar to Cyanobacteria, in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. Based on Field Emission Scanning Electron Microscopy (FESEM) and other measures, Dr. Hoover has concluded they are indigenous to these meteors and are similar to trichomic cyanobacteria and other trichomic prokaryotes such as filamentous sulfur bacteria. He concludes these fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. The implications are that...

    The term Nanobacteria is short for its scientific genus & species name Nanobacterium sanguineum, a Latin scientific term that means blood nanobacteria. Nanobacteria are nano-sized in that they are from 20-200 nanometers in size and are the smallest known self-replicating bacteria (a nanometer is 1 billionth of a meter and is approximately the width of ten hydrogen atoms side-to-side) Nanobacterium sanguineum is recognized as an emerging infectious disease. Nanobacteria have been shown to cause the calcification in coronary artery disease and vascular disease atherosclerotic plaque.

    ScienceDaily (Mar. 27, 2008) — Researchers from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn have detected for the first time a molecule closely related to an amino acid: amino acetonitrile. The organic molecule was found with a 30 metre radio telescope in Spain and two radio interferometers in France and Australia in the "Large Molecule Heimat", a giant gas cloud near the galactic centre in the constellation Sagittarius (Astronomy & Astrophysics, in press).  Amino acetonitrile. (Credit: Sven Thorwirth, MPIfR) The "Large Molecule Heimat" is a very dense, hot gas clump within the star forming region Sagittarius B2....

    The amino acid glycine, a fundamental building block of proteins, has been found in a comet for the first time, bolstering the theory that raw ingredients of life arrived on Earth from outer space, scientists said on Monday. Microscopic traces of glycine were discovered in a sample of particles retrieved from the tail of comet Wild 2 by the NASA spacecraft Stardust deep in the solar system some 242 million miles (390 million km) from Earth, in January 2004. Samples of gas and dust collected on a small dish lined with a super-fluffy material called aerogel were returned to Earth...

    Scientists have discovered amino acids, the building blocks of life in a meteorite where none were expected. The finding adds evidence to the idea that some of life's key ingredients could have formed in space, and then been delivered to Earth long ago by meteorite impacts. The meteorite in question was born in a violent crash, and eventually crashed into northern Sudan

    Amid a flurry of criticism, a NASA-funded team on Thursday backed off the more extravagant, textbook-changing claims they'd made about a bacterium that had allegedly substituted arsenic for phosphorus in its DNA. The original announcement, made at a NASA news conference Dec. 2, seemed to break a cardinal rule of biology that all organisms need some phosphorus to survive. NASA researchers claimed to have discovered an exotic organism in California's Mono Lake that lived instead on arsenic, thus broadening the types of life that may exist in the universe. The news made headlines worldwide including a New York Times story...

    I gave it the front-page treatment when the big announcement was made, so now the big skeptical response gets front-page treatment too. Simply devastating — so much so that I wonder why it fell to an outfit like Slate to put it together. Did the Times or WaPo not have enough of an inkling about NASA’s discovery to survey naysayers before writing up their reports on the “discovery”? This information would have come in a lot handier when everyone was still paying attention to this story. As soon Redfield started to read the paper, she was shocked. “I was outraged...

    Life in space? Not quite. But to scientists in the arcane field of astrobiology, it's still pretty cool. Scientists at NASA's Astrobiology Institute report they have found bacteria -- in Mono Lake, Calif., not in space -- that could be made to live on arsenic. The organism is called GFAJ-1. The finding is important because it expands the prevailing view of what it takes for living things to survive.

    Alan Boyle writes:NASA's secret is finally out: Researchers say they've forced microbes from a gnarly California lake to become arsenic-gobbling aliens. It may not be as thrilling as discovering life on Titan, but the claim is so radical that some chemists aren't yet ready to believe it. If the claim holds up, it would lend weight to the idea that life as we know it isn't the only way life could develop. Organisms with truly alien biochemistry could conceivably arise on a faraway exoplanet, or on the Saturnian moon Titan, or even here on Earth. "Our findings are a reminder...

    Take a hastily arranged NASA press conference, add a vague allusion to an “astrobiology discovery,” and you’ve got a recipe for mass web-fueled speculation that E.T. is finally coming home. On Tuesday, the U.S. space agency announced a press conference to be held at 2pm EST on Thursday to “discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life.” While that brief teaser is all NASA has said on the issue, many others have since taken to the web to complete the narrative. “If I had to guess at what NASA is going to reveal on...

    Incredible microbe found in California lakeNasa scientists are set to announce that bacteria have been discovered that can survive in arsenic, an element previously thought too toxic to support life, it can be revealed. In a press conference scheduled for tomorrow evening, researchers will unveil the discovery of the incredible microbe - which substitutes arsenic for phosphorus to sustain its growth - in a lake in California. The remarkable discovery raises the prospect that life could exist on other planets which do not have phosphorus in the atmosphere, which had previously been thought vital for life to begin. But it...

    NASA has set the interwebs a-tremble with a teasing announcement to the global media that a news conference will be held in Washington DC on Thursday "to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life". The space agency's routine ploy of trailing major briefings in advance has caused trouble before. In 2008, "revelations" that the White House had been informed of a NASA announcement's content before the media caused fevered speculation ahead of a briefing on data from the "Phoenix" polar Mars lander.

    Forests might be detectable on extrasolar planetsThanks to a new remote sensing technique, astronomers may soon be able to detect the presence of multicellular life (like trees) on planets outside of the Solar System. Excitingly, we've been able to detect the composition of atmospheres on a handful of planets orbiting other stars. But if next-generation space observatories go online within the next couple of decades, some scientists propose using a new technique to determine details such as tree-like multicellular life on extrasolar planets. While previous studies have discussed the likelihood of detecting life on exoplanets through signs of biogenic gases...

    Thirty years ago, NASA scientists noticed that two of their spacecraft, Pioneer 10 and Pioneer 11, were veering off course slightly, as if subject to a mysterious, unknown force. In 1998, the wider scientific community got wind of that veering—termed the Pioneer anomaly—and took aim at it with incessant, mind-blowingly detailed scrutiny that has since raised it to the physics equivalent of cult status. Now, though, after spawning close to 1000 academic papers, numerous international conferences, and many entire scientific careers, this beloved cosmic mystery may be on its way out.

    Harry Potter fans are looking forward to the boy wizard’s next screen adventure, when Harry Potter and the Half-Blood Prince opens this month. Pottermania broke loose when J. K. Rowling’s first book appeared on bookstands in 1997, prompting the creation of films, fan websites, and dozens of similarly themed books. Rowling’s world of wizardry has even inspired the name of a dinosaur fossil, Dracorex hogwartsia. But serious researchers are seeing evidence that dragons were more than just fantastical creatures...

    In September I participated in "Pale Blue Dot III: Searching for Life on Distant Words" at Chicago's Adler Planetarium. The other two Pale Blue Dot workshops were held in 1996 and 1999, both at NASA Ames Research Center. It is striking how much the world, and the worlds, have changed since then. Over 200 extrasolar planets have been discovered, and the Mars Exploration Rovers have shown evidence of surface water on another planet... The sessions each featured three scientific talks, and then a "media respondent" would present a journalist's perspective. Afterwards there would be a panel discussion, with the scientists...

    Questions about the existence of life in outer space may have a surprisingly close-to-home answer, according to one University of Houston professor. Understanding how life evolved on Earth is important in obtaining clues as to where else in the universe one might find life and what it might be like, said George E. Fox, a UH professor of biology and biochemistry. Fox is finishing work on a three-year research grant from NASA’s Exobiology Program that seeks to understand life’s origin. In addition to his Earth-based research, Fox collaborated with the Houston Museum of Natural Science (HMNS) on a film project...

    Are We Alone? A Tête-à-Tête Between Neil deGrasse Tyson and Peter Ward Despite decades of concerted effort by radio astronomers working on the project known as SETI, the Search for Extraterrestrial Intelligence, we've had no sign of beings elsewhere in the universe that match or exceed us in smarts. That's just one of many pieces of evidence that paleontologist Peter Ward, coauthor of Rare Earth: Why Complex Life is Uncommon in the Universe, points to when claiming that intelligent life beyond Earth must be exceedingly rare. Since many other scientists believe advanced life is common out there—Carl Sagan estimated...
