Deep sea methane scavengers captured
Scientists of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and the California Institute of Technology (Caltech) in Pasadena succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. view more (2008-05-14)
Microbes turn electricity directly to methane without hydrogen generation
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. view more (2009-03-31)
Microbes under Greenland Ice may be preview of what scientists find under Mars' surface
A University of California, Berkeley, study of methane-producing bacteria frozen at the bottom of Greenland's two-mile thick ice sheet could help guide scientists searching for similar bacterial life on Mars. view more (2005-12-15)
Novel protein complex enables survival in hostile environment
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. view more (2005-11-17)
Bold traveler's journey toward the center of the Earth
The first ecosystem ever found having only a single biological species has been discovered 2.8 kilometers (1.74 miles) beneath the surface of the earth in the Mponeng gold mine near Johannesburg, South Africa. view more (2008-10-10)
Did you know? The oldest organisms live in waste repositories
Some of the oldest organisms - Archaea - live in waste repositories. These microorganisms have lived on Earth for 3.8 billion years and some of them can produce methane, used as a renewable energy source. Cemagref scientists are trying to enhance their activities so that they produce methane more quickly. Why? In order to release the pollutants... view more... (2003-06-11)
Life under extreme contidions, microbiology of the hydrothermal vents
Microorganisms are found everywhere, even under the most extreme environmental conditions. These include extremely high temperature environments in which growth of certain Archaea - the most primitive forms of life - is possible at temperatures up to 110oC or higher, and hypersaline environments saturated with salt. The deep-sea hydrothermal vents... view more... (2003-05-29)
Hydrothermal vents: Hot spots of microbial diversity
Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL (Marine Biological Laboratory) and University of Washington's Joint Institute for the Study of Atmosphere and Ocean. view more (2007-10-05)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
B12 Is Also an Essential Vitamin for Marine Life
B12 - an essential vitamin for land-dwelling animals, including humans - also turns out to be an essential ingredient for growing marine plants that are critical to the ocean food web and Earth's climate, scientists have found. view more (2007-05-21)
Elevated Carbon Dioxide Changes Soil Microbe Mix Below Plants
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide (CO2) reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen. view more (2007-12-20)
Our microbes, ourselves
In terms of diversity and sheer numbers, the microbes occupying the human gut easily dwarf the billions of people inhabiting the Earth. Numbering in the tens of trillions and representing many thousands of distinct genetic families, this microbiome, as it's called, helps the body perform a variety of regulatory and digestive functions, many still... view more...

New life discovered in the deep Mediterranean
Scientists have discovered a new group of microbes thriving in extreme conditions deep in the Mediterranean Sea. Their existence in such hostile environments hints at the possibility of life on other planets. view more (2005-01-13)
Genomics reveals mechanism of heat resistance in bacteria
Warm-blooded creatures maintain a relatively stable body temperature that cannot tolerate the stress of intense heat (or cold). view more (2005-08-23)
Can Biosensors Find Life On Mars?
Is there life on Mars? Thanks to a £60k grant from the Engineering and Physical Sciences Research Council (EPSRC), a team from Cranfield University and the University of Leicester will try and find the answer. The team, led by Dr David Cullen from Cranfield's Biotechnology Centre and Dr Mark Sims at the Space Research Centre at the... view more... (2001-11-27)
Study reveals surprising details of the evolution of protein translation
A new study of transfer RNA, a molecule that delivers amino acids to the protein-building machinery of the cell, challenges long-held ideas about the evolutionary history of protein synthesis. view more (2008-08-13)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
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. view more (2009-07-10)
Rampant helper syndrome
The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes, being bacteria and higher organisms. view more (2009-07-06)
A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life. view more (2008-02-15)
Researchers make nanosheets that mimic protein formation
University of Michigan researchers have discovered a way to make nanocrystals in a fluid assemble into free-floating sheets the same way some protein structures form in living organisms. view more (2006-10-13)
