Alzheimer's research yields potential drug target
July 2, 2009
This illustrates the progression of AB42 to a toxic dodecamer, or, "twelve-mer" aggregation, . Below, the AB40 oligomer only becomes a nontoxic tetramer aggregation.
Going green with white biotech
July 1, 2009
Industrial or 'white' biotechnology has already begun to makes inroads into the chemicals sector, but with climate change and 'green' practices high on the agenda, how much of an impact is it likely to have? This was one of the debates taking place at Green Week, the European Commission's annual conference on climate change, held 23-26 June.

Alzheimer's Research Yields Potential Drug Target
Scientists at UC Santa Barbara and several other institutions have found laboratory evidence that a cluster of peptides may be the toxic agent in Alzheimer's disease. Scientists say the discovery may lead to new drugs for the disease. In an article published this week in Nature Chemistry, the researchers explain the process in which the toxic Amyloid Beta 42 peptides aggregate, and outline the new technology they use to study these peptides.
Longevity Of Dental Fillings May Be Increased By Nanotechnology
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings' longevity. "Dentin adhesives bond well initially, but then the hybrid layer between the adhesive and the dentin begins to break down in as little as one year," says Dr.
2009 Dr. Paul Janssen Award For Biomedical Research Won By Axel Ullrich
Johnson & Johnson has announced that Axel Ullrich, Ph.D., director of the Department of Molecular Biology at the Max Planck Institute of Biochemistry in Germany, whose discoveries have led to novel cancer therapies including Herceptin® (trastuzumab) , is the winner of the 2009 Dr. Paul Janssen Award for Biomedical Research. An independent committee of world-renowned scientists selected Dr. Ullrich, who on September 8 will receive a $100,000 prize during a ceremony in Beerse, Belgium.

CAS Registers 40 Millionth Substance
On November 21, CAS Registry Number 1073662-18-6 was assigned to an azulenobenzofuran derivative. The 40 millionth substance was identified by CAS scientists in a journal article published in Angewandte Chemie International Edition.
The Not-So-New Chemical Element 112
Recent headlines tout that "a new element" will soon be added to the 140-year-old periodic table of chemical elements. However, the super heavy element known as ununbium (Uub), or element 112, is far from new. In fact, it has been among the elements found on standard periodic tables for several years and included in CAS REGISTRY since 1975.
