Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the sample in the laboratory. Tests that work faster, in the field, and without complex sample ... more
Wiley Launches Mass Spectra of Designer Drugs 2005
John Wiley & Sons, Inc., announced the launch of Mass Spectra of Designer Drugs 2005 CD-ROM, the first complete update since 2003. This latest collection contains 2,959 chemical compounds and 3,437 mass spectra and structures of designer drugs, medicinal drugs, and warfare agents, and includes 100 of the most common chemical warfare compounds as well as the new designer drugs that have appeared on the market through the end of October 2004. The data contained in Mass Spectra of Designer Drugs 2005 have been gathered from crime labs across Europe and from both legal and underground literature, providing the most comprehensive database currently available on these compounds. The data include the chemical structure, chemical name, molecular formula, molecular weight (nominal mass), biological effect, and measurement conditions. The high quality of the spectra is proven by the average peak number per spectrum (146) and by an average quality index of 90 percent. Author Peter Rösner studied chemistry, pharmacology, and toxicology at the University of Kiel. In 1982 he joined the regional department of criminal investigation in Kiel and became the leader of the toxicology department, focusing on drug identification and structure elucidation with GC/MS. Since 1992 he has been a lecturer in mass spectrometry at the University of Kiel. Dr. Rösner received the Jean-Servais-Stas Award from the Society of Toxicological and Forensic Chemistry on April 15, 2005 in honor of his outstanding work on Mass Spectral Databases.

Biomass as a source of raw materials
For the protection of the environment, and because of the limited amount of fossil fuels available, renewable resources, such as specially cultivated plants, wood scraps, and other plant waste, are becoming the focus of considerable attention. Processes such as pyrolysis or liquefaction all ... more
Diagnosis and treatment in one go: Korean researchers led by Tae Gwan Park and Jinwoo Cheon have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making them macroscopically and microscopically visible. As they report in the journal Ang ... more
