Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere.   view more (2008-01-17)

Chemical Bonding States at Silicon / Silicon Dioxide Interfaces Characterisable with Light
The importance of characterising the atomic structure of the silicon / silicon dioxide interface as an essential component in highly integrated circuits has steadily increased as a result of continuing miniaturisation of silicon chips. The physicists, Dr. Stefan Bergfeld, Bjoern Braunschweig and... view more (2004-08-26)

Estrogens as antioxidants - reducing heart disease in younger postmenopausal women
HRT could be used to protect younger postmenopausal women from heart disease. An article published in the journal Lipids in Health and Disease shows that estrogens commonly used in HRT reduce the build up of harmful oxidised lipoproteins, which can lead to heart disease, by acting as antioxidants.   view more (2003-07-04)

New method of oxidising terpenes holds exciting possibilities for perfumery, flavouring and pharmaceuticals
Researchers in Oxford University’s Department of Chemistry have devised a new method of selectively oxidising terpenes to produce compounds of particular interest to the perfumery, flavour and pharmaceutical industries.   view more (2002-08-02)

Loma Linda University research confirms antioxidant-rich pecans protect against unhealthy oxidation
A new research study from Loma Linda University (LLU) shows that adding just a handful of pecans to your diet each day may inhibit unwanted oxidation of blood lipids, thus helping reduce the risk of heart disease.   view more (2006-09-29)

Production of 'mint-scent'
In the industry, many tons of alcohol are used annually, as a starting point for the synthesis of many substances. Alcohol first has to be oxidised, after which aromas such as mint or cinnamon, or substances needed for the production of nylon are produced. Until now heavy metals such as... view more (2000-03-03)

Attenuation of NASH by stimulation of free fatty acid metabolism
Medically-complicated obesity is a societal problem that needs to be solved. Liver disease, specifically non-alcoholic steatohepatitis or NASH, is just one of the many complications of increased body weight.   view more (2007-10-29)

New Catalysts Developed at Oxford for Fischer-Tropsch and Oxidation Reactions
Oxford University researchers have developed an innovative process for preparation of catalysts, termed the Organic Matrix Combustion Method. It produces extremely active, selective and long-lasting catalysts. The catalysts use economical metals such as nickel and cobalt, and have been prepared for... view more (2002-10-04)

Monell researchers find metabolic defect in liver that can lead to obesity
Researchers at the Monell Chemical Senses Center have identified a genetically-transmitted metabolic defect that can lead to obesity in some individuals.   view more (2007-07-25)

Fat still on the children's menu
Parents should think twice before offering a low-fat menu to youngsters, despite concerns over obesity.   view more (2007-08-16)

Scientists discover possible link between oxidative stress and non-hereditary degenerative disease
The irreversible neurological degeneration associated with Parkinson's and Alzheimer's diseases may be the consequence of oxidative stress-the imbalance of antioxidants and pro-oxidants in cells.   view more (2006-04-28)

Vitamin C depletion correlates with lower body fat, not weight loss during short-term diet
Too little vitamin C in the blood stream has been found to correlate with increased body fat and waist measurements.   view more (2006-04-04)

Porphyrin electron-transfer reactions observed at the molecular level
Researchers at Temple University have observed and documented electron transfer reactions on an electrode surface at the single molecule level for the first time, a discovery which could have future relevance to areas such as molecular electronics, electrochemistry, biology, catalysis, information... view more (2007-08-03)

Road to greener chemistry paved with nano-gold, researchers report
The selective oxidation processes that are used to make compounds contained in agrochemicals, pharmaceuticals and other chemical products can be accomplished more cleanly and more efficiently with gold nanoparticle catalysts, researchers have reported in Nature magazine.   view more (2005-10-26)

Scientists discover way to block growth of prostate cancer cells
Scientists have discovered for the first time a specific biochemical pathway by which the sex hormone, androgen, increases levels of harmful chemicals called reactive oxygen species (ROS) in the prostate gland that play a role in the development of prostate cancer.   view more (2006-11-08)

Quicker from Crude Oil to Silk Stockings
Specific Oxidation of Hydrocarbons Adipic acid is an important building block for a series of chemical products, for example synthetic material and fibers like Nylon - the material from which women's hosiery is made. On a large-scale, adipic acid, a hydrocarbon chain of six carbon atoms with an... view more (2000-06-29)

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... view more (2008-05-14)

BEER AS A REMEDY FOR DYSBACTERIOSIS
A scientist from Novosibirsk, Vladimir Baibakov has developed a recipe of the so-called bifidobeer - the beer which contains bifidobacteria similarly to bifidokefir. But why should beer contain bifidobacteria? Is not it too much of a good thing? Not at all. It appears that bifidobacteria contained... view more (2002-08-09)

Ammonia-loving archaea win landslide majority
A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth's most abundant land-based creatures that oxidize ammonia.   view more (2006-08-17)

NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon... view more (2008-09-08)

Heaps of climate gas - Pasturing cows convert soil to a source of methane
The cow as a killer of the climate: This inglorious role of our four-legged friends, peaceful in itself, is well-enough recognised, because, with their digestion, the animals produce methane, which is expelled continuously.   view more (2007-10-15)

How rusty is the Earth?
An iron object lying around outside quickly turns rusty. Iron metal always has to be combined with some other elements or coated with paint to stop it corroding. The reason for this is that iron metal is unstable in the presence of the oxygen in the Earth's atmosphere. It reacts with the iron to... view more (2004-06-10)

Brookhaven lab scientists stabilize platinum electrocatalysts for use in fuel cells
Platinum is the most efficient electrocatalyst for accelerating chemical reactions in fuel cells for electric vehicles. In reactions during the stop-and-go driving of an electric car, however, the platinum dissolves, which reduces its efficiency as a catalyst. This is a major impediment for... view more (2007-01-15)

Hibiscus Flowers to Prevent Heart Attacks
Hibiscus flower extract may have the same health benefits as red wine and tea according to new research by scientists in Taiwan. Hibiscus contains antioxidants that help control cholesterol levels and reduce heart disease, says the research in Journal of the Science of Food and Agriculture.   view more (2004-09-13)
