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)

Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women affected by the condition. view more (2008-08-06)
Finely tuned WspRs help bacteria beat body by building biofilm
Bacteria are particularly harmful to human health when they band together to form a biofilm-a sheet composed of many individual bacteria glued together-because this can allow them to escape from both antibiotics and the immune system of their host. view more (2008-03-25)
Scientists determine structure of enzyme that disrupts bacterial virulence
A team of biomedical researchers from Brandeis University and the University of Texas at Austin has determined the first 3-dimensional structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans. view more (2005-08-31)
New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)
New molecular insight into amboebic dysentery
