Betrayal Of The Aphids
2014-06-03 14:58:11

By Iqbal Pittalwala, University of California - Riverside Aphids are devastating insect pests and cause great losses to agriculture worldwide. These sap-feeding plant pests harbor in their body cavity bacteria, which are essential for the aphids' fecundity and survival. Buchnera, the bacterium, benefits also because it cannot grow outside the aphid. This mutually beneficial relationship is sabotaged, however, by the bacterium which proceeds to betray the aphid, a research team led by...

Max Planck scientists identify key player of protein folding Proteins are the molecular building blocks and machinery of cells and involved in practically all biological processes. To fulfil their tasks, they need to be folded into a complicated three-dimensional structure. Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now analysed one of the key players of this folding process: the molecular chaperone DnaK. “The...

Access to clean water is a necessity often taken for granted. However UNICEF estimates that 900 million people across the world do not have access to safe drinking water. New research published in BioMed Central's open access journal BMC Biotechnology shows that an enteric virus-binding protein (EVBP), isolated from bacteria found in activated sludge, is able to capture viruses often present in contaminated water. One of the difficulties in measuring viral contamination in water is that...

Physicists at UC Santa Barbara have created a microscopic device to assist biologists in making very fast molecular measurements that aid the understanding of protein folding. This development may help elucidate biological processes associated with diseases such as Alzheimer's and Parkinson's. Since proteins in the body perform different functions according to their shape, the folding process is considered a key area of study. Using a microfabricated fluid mixing device built at UCSB's...
