Grabbing addiction by the tail

Canadian scientists have developed some clever molecular trickery that is helping to reduce the drug cravings of addicted rats.

The researchers have sidestepped this problem by crafting a peptide that mimics a portion of the tail of the glutamate receptor and, once inside a neuron, serves as a decoy to prevent the loss of glutamate receptors. more

Evaluation of US research doctorate programs gets under way 

The National Research Council has launched its latest project to assess U.S. research doctorate programs. Like previous efforts in 1983 and 1995, the new study is designed to help universities improve the quality of these programs through benchmarking; provide potential students and the public with accessible, readily available information on doctoral programs nationwide; and enhance the nation's overall research capacity. Data will be available in 2007. more
