Understanding the oceans microbes is key to the Earth's future
Life on Earth may owe its existence to tiny microorganisms living in the oceans, but the effect of human-induced change on the vital services these microbes perform for the planet remains largely unstudied. view more (2005-12-09)
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)
Can you catch a bad back?
Two fifths of British adults have experienced back pain in the past year and it is one of the largest causes of work absence in the UK. Now, a collaborative project between researchers at Aston University, The Queen Elizabeth Hospital and The Royal Orthopaedic Hospital in Birmingham have carried out a successful study to find out if some back pain... view more...

Microorganisms helps us to drive more oil from the oil-bearing bed
When the reservoir pressure drops the oil field dries up though there is a lot of oil. To pump out the remains one has to apply pressure by pumping into the oil-bearing bed water or gas. Other method - to apply biotechnology. The oil is contaminated with specially bred mi-croorganism strains, which produce gas, acids and surface active agents... view more... (1999-08-18)
Marine bacterium suspected to play role in global carbon and nitrogen cycles
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. view more (2005-09-23)
Biosolids Microbes Pose Manageable Risk to Workers
Class B biosolids are sewage sludges that have been treated to contain fewer than 2.0 x 106 fecal coliforms/dry gram. view more (2008-10-28)
Fine-tuning lasers to destroy blood-borne diseases like AIDS
Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA. view more (2007-11-01)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
What can we do for prevention and therapy of anaerobe-associated infections?
Anaerobic microorganisms are important constituents of both human and animal intestinal microbiota. Infections caused by anaerobic bacteria are increasingly being recognized as major problem in clinical medicine. view more (2008-09-26)
BSE Residues: anaerobic digestion saves 45 million euros a year
The treatment of BSE residues through anaerobic digestion is, according to Quercus, the most efficient and fruitful way of resolving this environmental question. This is a biological process successfully put into practice in a national company, ITS Marques, and consists of the degradation of organic matter by microorganisms in the absence of... view more...

Genomics throws species definition in question for microbes
Until a decade ago, scientists categorized microorganisms almost exclusively by their physical characteristics: how they looked, what they ate, and the by-products they produced. view more (2007-03-27)
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)
Two novel species of bacteria isolated from oil wells
Oilfields usually represent extreme environments, where physicochemical conditions appear at first sight to be generally unsuitable for living organisms to develop. However, these environments, usually poor in nitrates and oxygen, harbour a rich diverse community of microorganisms. The most widely represented and best-known types are... view more... (2004-11-23)
Climate changes locked inside microfossils
Fossilised remains of sea creatures are commonly found in rocks in the mountains of the Basque Country. So, at some time in the past, Euskal Herria was under the sea. For example, during the Palaeocene period, some 65-55 million years ago. The region was then subtropical, and similar in appearance to the Australian Coral Reef. view more (2004-03-04)
Neutrophils in rheumatoid arthritis: How to lessen inflammation but still fight infection
Neutrophils, which quickly congregate at the sites of infection and inflammation, are capable of ingesting microorganisms or other particles. view more (2006-06-16)
Yale undergrads' Amazon trip yields a treasure trove of diversity
A group of Yale undergraduates have discovered dozens of potentially beneficial bioactive microorganisms within plants they collected in the Amazon rain forest, including several so genetically distinct that they may be the first members of new taxonomical genera. view more (2008-08-25)
Nutrient recycling - the ideal way to avoid nutrient limitation in a grazer community
The rocky shore of Lake Erken, Sweden, is inhabited by the sessile psychomyiid caddisfly Tinodes waeneri (L.). The larva lives in a gallery, consisting of a spun silken web plus other organic and inorganic material associated with the web (Danecker 1961, Becker 1993, Hasselrot 1993a). The additional organic material includes detritus and living... view more... (2000-01-17)
Nature's helpers: Using microorganisms to remove TCE from water
In 2002, Bruce Rittmann, PhD, director of the Biodesign Institute's Center for Environmental Biotechnology, received a patent for an innovative way to use nature to lend society a hand. view more (2008-02-29)
Harvesting Arctic algae
Microorganisms living in the depths of the oceans under conditions unbearable for humans utilize hot springs to produce their energy and substances. Some bacteria and algae feel right at home in the boiling waters of a geyser and others in acid ponds or salt waters. Still others populate glaciers and snow fields. For many years, researchers have... view more... (2002-09-20)
