DNA: Bacteria's survival ration

...ompetence is potentially risky, Finkel said, since bad mutations can result, "but there should be no genetic cost to eating [the DNA]." The study identified eight genes in E. coli that are necessary for nutritional competence. Without any one of these genes, the bacteria cannot consume DNA and lose thei...

Cell phone emissions excite the brain cortex

... that this work implies that using a cell phone is bad for the brain in any way. Much more work needs to be done to understand whether these electrical changes in the brain make any difference whatsoever in the way we think or in any disease process in which cortical excitability is affected. "It shou...

Mechanism identified for promising neurological drug

...degenerative diseases, inflammation is basically a bad thing, because it damages cells," Swanson notes. "And cell suicide is not necessarily the best thing for the whole organism." Is he being understated? The second observation, Swanson says, was made a decade ago by study co-author Tiina M. Kauppinen,...

Bubbles go high-tech to fight tumors

...bbles: You've bathed in them, popped them, endured bad song lyrics about them. Now, University of Michigan researchers hope to add a more sophisticated application to the list---gas bubbles used like corks to block oxygen flow to tumors, or to deliver drugs.
