E. coli engineered to produce important class of antibiotic, anti-cancer drugs
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have taken a major step forward in the field of metabolic engineering, successfully using the bacterium Escherichia coli to synthesize a class of natural products known bacterial aromatic polyketides, which include important antibiotic and anticancer drugs. view more (2008-12-23)
Scientists solve mystery of polyketide drug formation
Many top-selling drugs used to treat cancer and lower cholesterol are made from organic compounds called polyketides, which are found in nature but historically difficult for chemists to alter and reproduce in large quantities. view more (2008-04-02)
Blue tits love the smell of perfumed nests!
French birds love the smell of perfumed nests. In an article published this month in Ecology Letters, scientists from the Centre National de Recherche Scientifique report that a small cavity-nesting bird on the island of Corsica, the blue tit, adorns its nests with fragments of strongly perfumed plants, including lavender and mint. The chemical... view more... (2002-07-11)
Researchers confirm benzene-like electron delocalization of important molecule
Researchers in the lab of University of Oregon chemist Shih-Yuan Liu have successfully synthesized and structurally characterized boron-nitrogen compounds that are isoelectronic and isostructural to the fundamentally important benzene molecule. view more (2008-06-20)
Bioavailable contaminants come from the Exxon Valdez oil catastrophe
Contaminants from natural coal deposits in the Gulf of Alaska are not easily bioavailable, unlike the crude oil from the Exxon Valdez tanker catastrophe. view more (2009-08-31)
Promising Talents Of A Wild Bacterium
A wild strain of E. coli possessing completely original properties has been discovered in shea cake, a residue of a tropical food industry used in cosmetics, by IRD scientists working in microbial biotechnology found the strain, designated “ C2 ”, had the ability to transform certain polluting aromatic acids into other, non acid,... view more...

Chemical industry helped by small invisible tube
Chemists at Utrecht University have developed a catalyst for fine chemistry. Tiny tubes of graphite are the carrier for this catalyst. PhD student Tijmen Ros successfully tested the catalyst with a standard reaction. Fellow researchers are now making the catalyst suitable for the production of cinnamon alcohol, an aromatic substance and... view more... (2002-01-24)
New study expands the list of hazardous chemicals in smokeless tobacco
Attention all smokeless tobacco users! It's time to banish the comforting notion that snuff and chewing tobacco are safe because they don't burn and produce inhalable smoke like cigarettes. view more (2009-08-17)
Do the hyper-coordinate planar transition metal atoms exist?
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding... view more... (2008-07-01)
UCLA researchers reconstitute enzyme that synthesizes cholesterol drug lovastatin
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have for the first time successfully reconstituted in the laboratory the enzyme responsible for producing the blockbuster cholesterol-lowering drug lovastatin. view more (2009-11-04)
NRL scientists produce carbon nanotubes using commercially available polymeric resins
Scientists at the Naval Research Laboratory (NRL) have successfully produced carbon nanotubes (CNTs) in high yields in bulk solid compositions using commercially available aromatic containing resins. view more (2008-02-11)
Hydrocarbons in the Horsehead mane
Observing the edge of the famous Horsehead Nebula with the IRAM interferometer located on the Plateau de Bures (France), a team of French and Spanish astronomers discovered a large quantity of small hydrocarbon molecules. This is a surprise because the intense UV radiation illuminating the Nebula should destroy the small hydrocarbons near the... view more... (2005-02-21)
How basil gets its zing
The blend of aromatic essential oils that gives fresh basil leaves their characteristic warm and sweet aroma is well characterized but not much is known about the enzymatic machinery manufacturing the odiferous mix. Researchers at the Salk Institute for Biological Studies and the University of Michigan followed their noses and solved part of the... view more... (2007-10-03)
Scientists find way to clean up the drugs market
Researchers from the University of Cambridge and the Massachusetts Institute of Technology have made a breakthrough by using supercritical carbon dioxide (scCO2) as a reaction medium for the preparation of molecules of interest to the pharmaceutical industry. view more (2004-09-13)
U.S.-German Research Consortium Sequences Genome of Versatile Soil Microbe
In a successful transatlantic collaboration, scientists at The Institute for Genomic Research (TIGR) in Rockville, MD, and at four research centers in Germany have deciphered and analyzed the complete genome of a bacterium, Pseudomonas putida, that has the potential to be used to remediate organic pollutants in soil as well as to help promote... view more...

The turbidity of wine has an influence on the aroma of the ferment, but not on the accumulation of biogenic amines
The turbidity of red wine during its ageing in oak casks has an influence on the accumulation of volatile compounds and, thereby, on the wine's aroma, but not on the accumulation of biogenic amines. view more (2006-11-28)
Nano design adjustment may help find, clear some water contaminants
Experiments designed to test discrepancies in theoretical computational chemistry have turned up a barely two-angstrom difference that may lead to a new approach to locate and remove dangerous toxins such as perchlorate and nitrates from the environment. view more (2006-12-14)
Breakthrough in Molecular Genetics of Strawberry
The world's first molecular map for wild strawberry (Fragaria) constructed using transferable DNA markers has been produced by scientists at East Malling Research (EMR) in association with collaborators at the University of Reading. view more (2004-12-08)
Better measurement procedures mean safer workplaces
Isocyanates and amines are chemicals used in the production of polyurethane (PUR). PUR is one of the most common plastics, used in products like hard and soft foam (insulation, cushions, mattresses, sponges, etc.), glue, paint, and elastomers. Isocyanates can cause respiratory disorders, and today they are one of the most common causes of... view more... (2004-09-08)
Even natural perfumes may cause allergies
Hypersensitivity to perfumes is the most common contact allergy in adults. Research at the University of Gothenburg has demonstrated that even natural aromatic oils, which many deem harmless compared to synthetic perfumes, may cause allergic reactions. view more (2009-02-04)
