How Well Do Antimicrobial Products Kill Biofilms?

Scientist Darla Goeres knows that there is more than one way to grow a biofilm, a fact that she uses to make sure that when a product claims it kills "99 percent" of bacteria, it really does the job. Biofilms are the extremely common communities of bacteria that form on most wet surfaces. They range from the plaque on teeth to the slime on streamside rocks to the sludge that clogs pipes.

'Cutting By Color': New Imaging Technique For More Precise Cancer Surgery

Instead of "paint by number," you might call it "cutting by color": Researchers in Massachusetts now report development and early clinical trials of a new imaging system that highlights cancerous tissue in the body so that surgeons can more easily see and remove diseased tissue with less damage to normal tissue near the tumor. Their research will be presented in August at the American Chemical Society national meeting in Philadelphia.
