DNA Recombination and Repair—A New Twist to RecA Function

...drolysis occurs all along its length. Under their experimental conditions, the authors found that a RecA molecule hydrolyzed 20 ATPs per minute—or one ATP every three seconds. If ATP hydrolysis occurred randomly in the fiber, one would expect a RecA molecule to dissociate about once every 1.5 seconds, or 40 RecA...

New studies suggest airborne SARS transmission is possible

... there in March 2003. Their results mark the first experimental confirmation of the presence of the SARS virus in the air of an infected patient's hospital room. The authors cautioned that their results do not document any cases of airborne transmission of the SARS virus from one person to another, only the diss...
