Surprising new species of light-harvesting bacterium discovered in Yellowstone

07-26-2007 · EurekAlert!

In the hot springs of Yellowstone National Park, a team of researchers has discovered a novel chlorophyll-producing bacterium that transforms light into chemical energy. The researchers also discovered that the new genus and species belongs to a new phylum, Acidobacteria -- only the third time in the past 100 years that a new bacterial phylum has been added to the list of those with chlorophyll-producing members, of which there are now only six.

    In the hot springs of Yellowstone National Park, a team of researchers partially funded by the National Science Foundation discovered a new bacterium that transforms light into chemical energy. The discovery of the chlorophyll-producing bacterium, Candidatus chloracidobacterium (Cab.) thermophilum, is described in the July 27, 2007, issue of Science in a paper led by Don Bryant of Penn State University and David M. Ward of Montana State University.

  2. Massive dinosaur discovered in Antarctica sheds light on life, distribution of sauropodomorphs
    12-10-2007 · EurekAlert!
    A new genus and species of dinosaur from the Jurassic has been discovered in Antarctica. The massive plant-eating primitive sauropodomorph is called Glacialisaurus hammeri and lived about 190 million years ago. The fossils were painstakingly removed from the ice and rock using jackhammers, rock saws and chisels under extremely difficult conditions over two field seasons. The long-necked herbivorous sauropods were the largest animals to walk the earth. They include Diplodocus and Apatosaurus.

  4. New light-sensing ability discovered in disease-causing bacteria
    08-23-2007 · EurekAlert!
    The bacteria that cause brucellosis can sense light and use the information to regulate their virulence. The discovery comes after 120 years of research into the disease, which causes abortions in livestock and fevers in humans. Researchers found that two other bacteria, including a species that attacks plants, sense light using the same type of protein structure, and at least 94 more species possess the code for it in their DNA.

  5. Intergalactic 'shot in the dark' shocks astronomers
    12-18-2007 · EurekAlert!
    A team of astronomers has discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collection of stars, gas, and dust. This "shot in the dark" is surprising because the type of explosion, a long-duration gamma-ray burst, is thought to be powered by the death of a massive star.

  6. Biologists expose hidden costs of firefly flashes
    09-19-2007 · EurekAlert!
    Tufts University biologists have discovered a dark side behind the light shows put on by fireflies each summer. While it's energetically cheap for fireflies to produce their distinctive flash signals, flashier males are more likely to end up on the dinner table. The importance of these two conflicting forces could shift in different firefly populations. It is possible that this evolutionary balancing act might generate entirely new firefly species with their own distinctive flash codes.

  7. Single-pixel Camera Takes High-res Images: Engineers Use New Mathematics And Micro Mirrors In ...
    10-02-2006 · ScienceDaily
    Using new mathematics and a silicon chip covered with hundreds of thousands of bacterium-sized mirrors, Rice University engineers have designed a time-multiplexed camera that takes high-resolution images with a single photodiode. Today's battery-hungry megapixel cameras contain millions of photodiodes, but Rice's camera creates an image by capturing one pixel of light several thousands of times in succession. The research will be presented October 11 at Frontiers in Optics 2006 in Rochester, New York.

    A professor at the University of Wisconsin-Milwaukee has been helping the Department of Energy analyze the genome of a "paper-eating" bacterium that could have uses in producing ethanol, but also shed light on how "gliding" bacteria move. The two functions could be related.

  9. Curbing C. difficile's toxin production
    09-05-2007 · EurekAlert!
    Researchers at Tufts University have discovered how the protein CodY controls toxin production of Clostridium difficile, a bacterium that has caused epidemics of severe diarrhea in hospital patients. In its search for food, C. difficile releases toxins that cause diarrhea and in rare cases death. Gaining a better understanding of how CodY prevents C. difficile from making toxins may lead to future drug development based on the properties of CodY.

    A three-week scientific expedition to French Frigate Shoals in the Northwestern Hawaiian Islands Marine National Monument returned to Honolulu on Sunday with the discovery of many new species and a better understanding of marine biodiversity in the Hawaiian Archipelago. Over 100 new species records are expected from the French Frigate Shoals alone.
