Latest Archaea Stories
In the world of microbes, as in politics, some groups just can't seem to shake the label "extremist." So it is with archaea (ar-KEY-uh), a collection of bacteria-like microorganisms whose unique genetics and chemical structure separate them from all other living things.
Like explorers of old, scientists are venturing into the immense but little-known realm of the microscopic organisms that dominate our planet.
A class of especially hardy microbes that live in some of the harshest Earthly environments could flourish on cold Mars and other chilly planets, according to a research team of astronomers and microbiologists.
We may not be entirely human, gene experts said on Thursday after studying the DNA of hundreds of different kinds of bacteria in the human gut.
Deeply buried ocean sediments may house populations of tiny organisms that have extremely low maintenance energy needs and population turnover rates of anywhere from 200 to 2,000 years, according to an international team of researchers.
One day, humans will step foot on Mars. And they'll be hungry. Growing food on a frozen desert planet with a suffocatingly thin atmosphere, however, will be a challenge. Scientists are now bioengineering plants that can grow on mars.
Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth.
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. Researchers have discovered the first Archaea known to oxidize ammonia for energy and metabolize carbon dioxide by successfully growing the tentatively named, Nitrosopumilus maritimus, in the lab.
The National Science Foundation has awarded a University of Colorado at Boulder research group $1.75 million to identify and analyze a potpourri of microbes new to science that are residing in the harsh, cold climate of Colorado's high mountains.
An experiment in a dry Antarctic stream channel has shown that a carpet of freeze-dried microbes that lay dormant for two decades sprang to life one day after water was diverted into it, said a University of Colorado at Boulder researcher.
