Latest Archaea Stories

2014-04-08 10:58:47

New insights into a surprisingly flexible immune system present in bacteria for combating viruses and other foreign DNA invaders have been revealed by researchers from New Zealand's University of Otago and the Netherlands. A team led by Dr Peter Fineran of the Department of Microbiology and Immunology are studying the genetic basis of adaptive immunity in bacteria that cause potato 'soft rot' and in E. coli bacteria. Through their recent collaboration they have found that these bacterial...

Global Warming Could Increase Methane Emissions From Freshwater Ecosystems
2014-03-19 17:22:42

University of Exeter New research led by the University of Exeter suggests that rising global temperatures will increase the quantity of the key greenhouse gas methane emitted from freshwater ecosystems to the Earth's atmosphere – which could in turn lead to further warming. The collaborative study, led by Dr Gabriel Yvon-Durocher from the University of Exeter, collated data from hundreds of laboratory experiments and field surveys to demonstrate that the speed at which methane fluxes...

Hannah Hickey, University of Washington The phrase, 'Eat your vitamins,' applies to marine animals just like humans. Many vitamins, including B-12, are elusive in the ocean environment. University of Washington researchers used new tools to measure and track B-12 vitamins in the ocean. Once believed to be manufactured only by marine bacteria, the new results show that a whole different class of organism, archaea, can supply this essential vitamin. The results were presented Feb. 24 at...

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...

A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep normal replication processes and reproduce by the back door, researchers at The University of Nottingham have found. The study, published in the journal Nature, centers on Haloferax volcanii — part of a family of single-celled organisms called archaea that until recently were thought to be a type of bacteria. The findings, led by scientists from the University's School of Life...

Sediments From The Deep Sea Give Insight Into Dynamics Of The Deep Biosphere
2013-10-22 14:53:38

Max Planck Institute Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus have investigated microbial life from this habitat. This "Deep Biosphere", reaching several hundred meters below the seafloor, is exclusively...

Promiscuous Extremophiles Better Oil Spill Cleanup
2013-10-01 09:51:10

Brett Smith for redOrbit.com - Your Universe Online Researchers working in Antarctica have created a detailed ecological picture of so-called extremophile bacteria living in extremely salty water that can hit temperatures of -4 degrees Fahrenheit. The bacteria found in Vestfold Hills, Deep Lake – known as haloarchaea – are giving scientists new information on how life can survive in such dire conditions. They could also potentially provide new tools for bioengineering techniques,...

Dark Ocean Carbon Absorption Not Enough To Restrict Global Warming
2013-09-06 07:46:40

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of Iowa shows that although microbes that live below 600 feet where light doesn’t penetrate – the so called “dark ocean”-- might not absorb enough carbon to curtail global warming, they do absorb considerable amounts of carbon, meriting further study. The findings of this study were published in the International Society of Microbial Ecology Journal. While many people are familiar with the...

Dark Matter In The Biological Realm
2013-07-17 04:31:08

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online A hot topic in astronomy is the search for dark matter - mass that seems to dominate the Universe, yet eludes our detection. Similarly, the field of biology encounters its own "dark matter" problem. Microbial dark matter, as it's called, draws its parallels from its cosmological cousin in that it is all around us, dominating this Earthly domain. Yet, it is incredibly difficult to characterize. "Microbes are the most abundant...
