Signs Of Ancient Bacterial Ecosystems Found In Australia
2013-11-13 05:44:54

April Flowers for redOrbit.com - Your Universe Online Scientists trying to reconstruct the rise of life during the period of Earth's history when it first evolved find the task daunting because the planet's oldest sedimentary rocks are not only rare, but nearly always altered by hydrothermal and tectonic activity. A new study, published in the journal Astrobiology, reveals the well-preserved remnants of a complex ecosystem in a nearly 3.5 billion-year-old sedimentary rock sequence in...

Martinson-Nicholls new Sof-Tred, Sof-Tyle, Comfort-Eze & Airug® Disposable Surgical Mats are ergonomically designed to reduce back, leg, foot and ankle fatigue. Unlike post applied topical agents, the antimicrobial agent used for these mats is incorporated directly into the foam compound during manufacturing ensuring that it won't wear off. Cleveland, Ohio (PRWEB) December 31, 2012 Martinson-Nicholls announces its new Anti-fatigue, Antimicrobial Healthcare Matting that provide...

Researchers Find Freshwater Springs, Numerous Micro-organisms In The Dead Sea

[ Watch the Video ] Findings are the result of collaboration between researchers from Ben-Gurion University of the Negev and the Max Planck Institute of Marine Microbiology Ben-Gurion University of the Negev (BGU) researchers have discovered deep freshwater springs on the Dead Sea floor that feed into this rapidly dwindling body of water. In the first-ever Dead Sea diving expedition, the researchers also found new types of micro-organisms growing around fissures in the sea floor as...

A University of Alberta-led research team has discovered that billions of years before life evolved in the oceans, thin layers of microbial matter in shallow water produced enough oxygen to support tiny, mobile life forms. The researchers say worm-like creatures could have lived on the oxygen produced by photosynthetic microbial material, even though oxygen concentrations in the surrounding water were not high enough to support life. The research was conducted in shallow lagoons in Venezuela...

The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 billion-year-old ocean floor rocks. Their findings suggest that the early ocean was much more temperate and that, as a result, life likely diversified and spread across the globe much sooner in Earth's history than has been generally theorized. It also means that the chemical composition of the ancient ocean...

A NASA-funded study suggests humans might not exist today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes. Biologist James Lake of the UCLA Center for Astrobiology compared proteins present in more than 3,000 different prokaryotes -- a type of single-celled organism without a nucleus -- and discovered two major classes of relatively simple microbes fused together more than 2.5 billion years ago. That endosymbiosis, or merging of two cells, he said,...

Findings may provide insight into the origins of life on Earth, and even the search for life on Mars Stromatolites are dome- or column-like sedimentary rock structures that are formed in shallow water, layer by layer, over long periods of geologic time. Now, researchers from the California Institute of Technology (Caltech) and the Jet Propulsion Laboratory (JPL) have provided evidence that some of the most ancient stromatolites on our planet were built with the help of communities of equally...

Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere."We used to believe that microbes only consumed methane in marine anaerobic sediment if sulfate was present," said Emily Beal, graduate student...

WASHINGTON -- The wonderland known as Yellowstone National Park has yielded a new marvel - an unusual bacterium that converts light to energy. The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth. "This thing was just bizarre," David M. Ward, a professor of microbial studies at Montana State University, said of the bacterium. Plants use photosynthesis to turn light into energy, of course, and so do some other bacteria. But, Ward said, the...

LONDON (Reuters) - Rock formations in Western Australia may not only be some of the earliest evidence of life on Earth but also the first signs of biodiversity, scientists said on Wednesday. Doubts about whether the formations known as stromatolites were signs of ancient life have persisted since they were described almost three decades ago. Some scientists believe they were formed by micro-organisms that lived on Earth more than 3 billion years ago. Others argued that they were...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
