Molds for Molecules
Molecular imprints in polymers as reaction vessels for pharmaceuticals research Materials with the tiniest of cavities, which can take up other molecules as "guests", play a meaningful role in science and technology. A particularly interesting process for the synthesis of materials with precisely fitted cavities is known as molecular imprinting.... view more... (2002-11-28)
Anti-fungal drug offers great benefits to some with severe asthma
Some patients with severe asthma who also have allergic sensitivity to certain fungi enjoy great improvements in their quality of life and on other measures after taking an antifungal drug, according to new research from The University of Manchester in England. view more (2008-12-29)
Batch control makes chemical reactions easier to manage
Two Dutch researchers have developed a method for managing so-called batch productions. During a batch production, substances react in a reactor vessel according to a certain recipe to produce an end product. After the reaction the reactor is emptied and a new reaction with the same recipe is started. Chemist Eric van Sprang and chemical engineer... view more... (2004-04-13)
Fishy diet in early infancy cuts eczema risk
An infant diet that includes fish before the age of 9 months curbs the risk of developing eczema, indicates research published ahead of print in the Archives of Disease in Childhood. view more (2008-09-25)
University of Pennsylvania Chemists Reinvent the Science and Industry of Making Plastics
Chemists at the University of Pennsylvania have created a new process for free radical polymerization, the chemical reaction responsible for creating an enormous array of everyday plastic products, from Styrofoam cups to PVC tubing to car parts. view more (2006-10-13)
Hayfever hope
With the peak grass pollen season approaching, scientists can reveal that a daily dose of probiotic can change the immune status of people with hay fever. view more (2008-06-03)
Early exposure to common viral infection does not protect against allergy
Common viral infections in early childhood do not protect against allergy, concludes research in Thorax. If anything, the evidence points to an increased risk. view more (2002-04-25)
Solution to elusive problem
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions. To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and therefore difficult to detect. Freezing... view more... (2003-01-21)
How left-handed amino acids got ahead: a demonstration of the evolution of biological homochirality in the lab
A chemical reaction that demonstrates how key molecules in the biological world might have come to be predominately left or right handed has been reported by scientists at Imperial College London. Ever since discovering that the building blocks of the biological world, such as amino acids and sugars, are distinctively left or right handed -... view more... (2004-06-21)
Scientists shed light on the mystery of photosynthesis
Scientists at the University of Sheffield are part of an international team that has become the first to successfully discover how the component parts of photosynthesis fit together within the cell membrane. In a paper, The native architecture of a photosynthetic membrane, published in Nature on 26 August 2004, they describe how the configuration... view more... (2004-08-25)
Pitt professor designs less-risky reactor for clean, safe energy
Reactors that burn hydrogen or natural gas to generate energy can be dirty and dangerous. The mix of air with hydrogen or natural gas can explode easily if composition and temperature are not carefully controlled. And reactors often produce polluting byproducts. view more (2006-09-13)
Gut worms may protect against house-dust mite allergy
A study conducted in Vietnam has added further weight to the view that parasitic gut worms, such as hookworm, could help in the prevention and treatment of asthma and other allergies. view more (2009-09-29)
Thioethers synthesis process
Although today there exists a number of methods for the synthesis of organic molecules (the main components of certain medicines, foods, additives, paints, fabrics, liquid crystals, etc.), in most cases toxic reagents and solvents have to be used. view more (2007-04-03)
Chimps, like humans, focus on faces
A chimp's attention is captured by faces more effectively than by bananas. A series of experiments described in BioMed Central's open access journal Frontiers in Zoology suggests that the apes are wired to respond to faces in a similar manner to humans. view more (2009-07-23)
NIH selects LIAI for major study on allergy molecular causes and possible treatments
A major study that will provide a new window into understanding and potentially treating allergies will be conducted by the La Jolla Institute for Allergy & Immunology (LIAI) under a $5 million federal contract. view more (2007-11-14)
Small molecule interactions were central to the origin of life
In an important new paper forthcoming in the June issue of The Quarterly Review of Biology, Robert Shapiro (New York University) argues against the widely held theory that the origin of life began with the spontaneous appearance of a large, replicating molecule such as RNA. view more (2006-05-17)
A better way to copy DNA
Scientists have developed a new method for DNA amplification that could replace the polymerase chain reaction (PCR), a technique that is invaluable for both medical diagnostics and basic research but which is confined to the laboratory. In the August issue of EMBO reports, Huimin Kong and colleagues at New England Biolabs (Beverly, MA, USA)... view more... (2004-07-14)
Scientists discover new chemical reaction for DNA production in bacteria and viruses
A team of researchers has discovered a new chemical reaction for producing one of the four nucleotides, or building blocks, needed to build DNA. view more (2009-04-17)
Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme. view more (2006-04-06)
What gives us sunburn protects crayfish against bacteria
The production of melanin gives us sunburns, but it also helps invertebrate animals to encapsulate attacking fungi and parasites. view more (2007-09-25)
