...white blood cells. This way, the researchers could tease out the effects of antibodies alone on the virus, independent of the rest of the immune system. The results, based on tests of 19 patients over 39 months, showed that most patients developed a high concentration, or titer, of antibodies to HIV withi...Pacific Northwest chemist wins national award for studies of biological systems

Berkeley - As biologists try to tease out the finer details of the green plant family tree, one key may lie in the cellular organelle - the chloroplast - that makes green plants green. As the photosynthetic factory of the plant cell, the chloroplast contains its own complement of genes d...NSF awards $37.9 million in grants to study biocomplexity in the environment
