To see if ADAR functions were related to the RNAi pathway, Bass and Tonkin made strains of the worm with mutations in both the ADAR g...Telescience recognized for facilitating biomedical research on a global network
The United States has not placed a high voltage electron microscope in service for biomedical research since the 1970s, yet access to these microscopes is vital for the study of disorders such as Alzheimer's and Parkinson's disease as well as mental retardation. To offset this obst...Researchers find mechanism bacteria use to target specific chemical contaminants
