Photosynthesis-Activating Protein Likely Predates Oxygen On Earth
2014-02-09 08:21:12

[ Watch the Video: Photosynthesis Older Than Oxygen ] redOrbit Staff & Wire Reports – Your Universe Online Thioredoxin, a protein essential to the process of photosynthesis in plants, likely developed on Earth long before oxygen ever became available, according to a study published in last week’s early online edition of the Proceedings of the National Academy of Sciences. In the study, an international team of researchers analyzing methane-producing microbes found that...

A team of researchers led by Virginia Tech and University of California, Berkeley, scientists has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available. The research opens new scientific areas in the fields of evolutionary biology and microbiology. The work also has broad societal implications as it allows scientists to better understand the production...

Unexpected Properties Of Methane-producing Microbe Revealed
2013-11-19 08:31:36

University of Massachusetts at Amherst Derek Lovley's lab at UMass Amherst show for the first time that one of the most abundant methane-producing microorganisms on Earth makes direct electrical connections with another species to produce the gas in a completely unexpected way For 40 years, scientists thought they understood how certain bacteria work together to anaerobically digest biomass to produce methane gas, important in bioenergy and the major source of greenhouse gas. But now...

Microbial Life In Undersea Volcanoes Provide Exciting New Research Opportunities

Brett Smith for redOrbit.com - Your Universe Online Although some have estimated a third of the Earth's biomass lives in our planet's rocks and sediments, little is known about these hard to reach organisms. A new report published in the Proceedings of the National Academy of Sciences (PNAS), with possibly wide reaching implications, looks to study one group of methane-producing microbes that live deep in the cracks of hot undersea volcanoes. Because of the alien nature of these...

Matt Shipman, North Carolina State University Researchers have long known that landfills produce methane, but had a hard time figuring out why "“ since landfills do not start out as a friendly environment for the organisms that produce methane. New research from North Carolina State University shows that one species of microbe is paving the way for other methane producers. Specifically, the researchers found that an anaerobic bacterium called Methanosarcina barkeri appears to be the key...

McGill microbiologist looks at Martian-like environment on Earth and finds evidence of bacteria Researchers at McGill's department of natural resources, the National Research Council of Canada, the University of Toronto and the SETI Institute have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North. Dr. Lyle Whyte, McGill University microbiologist explains that the Lost Hammer spring supports microbial life, that...

The Earth's original atmosphere held very little oxygen. This began to change around 2.4 billion years ago when oxygen levels increased dramatically during what scientists call the "Great Oxidation Event." The cause of this event has puzzled scientists, but researchers writing in Nature have found indications in ancient sedimentary rocks that it may have been linked to a drop in the level of dissolved nickel in seawater. "The Great Oxidation Event is what irreversibly changed surface...

U.S. scientists say they've discovered microbes can directly convert carbon dioxide and water to methane without generating hydrogen. Pennsylvania State University Professor Bruce Logan said his team made the discovery while studying making hydrogen in microbial electrolysis cells. We kept getting all this methane, he said. We may now understand why. Methanogenic microorganisms produce methane in marshes and dumps but scientists thought the organisms turned hydrogen or organic materials, such...

A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. "We were studying making hydrogen in microbial electrolysis cells and we kept getting all this methane," said Bruce E. Logan, Kappe Professor of Environmental Engineering, Penn State. "We may now understand why." Methanogenic microorganisms do produce methane in marshes and...

The benefits to animals of omega 3 fatty acids in fish oils have been well documented "“ helping the heart and circulatory system, improving meat quality and reducing methane emissions. These last two benefits may only apply to cows but lowering emissions is important for the environment, as methane given off by farm animals is a major contribution to greenhouse gas levels. Today (Monday 30 March) researchers from University College Dublin reported that by including 2% fish oil in the...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
