Special Report: Tools For Neuroscience's Third Decade
Laurel Joyce | Oct 28, 1990 | 10+ min read
Neuroscientists are entering the federally designated "Decade of the Brain" armed with a toolbox bulging with new instruments and techniques. Many have been borrowed from other disciplines; others have been specifically designed to probe the secrets of the nervous system. The variety of tools available reflects the diversity of the researchers who consider themselves neuroscientists. "Neuroscience represents a fusion of several scientific disciplines--biophysics, biochemistry, physiology, anat
New Molecular Tools Enable Researchers To Correlate Viruses, Diseases

Viruses, Diseases Author: Karen Young Kreeger Sidebar: Professional Resources for Viral Disease Researchers In the mid- to late 1980s, numerous correlations were discovered between viruses and various types of cancers. For example, Epstein-Barr virus was associated with nasopharyngeal carcinoma and B-cell lymphoma, hepatitis B virus with liver cancer, and human papillomavirus with cervical cancer. Now, a decade later, basic and clinical scientists are finding out that viruses may also play a r

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

For Detecting Pathogen-Specific PCR Products The DNA Catcher Plate System includes a line of 96-well oligo plate assays for the detection of pathogen-specific polymerase chain reaction (PCR) products. Kits include HIV, HBV, HCV, HCMV, HSV, VZV, HHV-6, Borrelia burgdorferi, and custom applications. The company's method for attaching a high-density capture probe to a 96-well microtiter plate allows single-copy detection of amplified DNA in a reverse dot blot format. Amplification of the target
