Naturally occurring asbestos linked to lung cancer

...scientists when passive smoking was found to cause lung cancer. "Like smoking, exposure to asbestos appears to be very dose-dependent," Beckett said. "Day-in, day-out occupational exposures are more dangerous than intermittent exposures in the community. But the more you can do to reduce your personal exp...

Emerging staph strains found to be increasingly deadly and deceptive

...e is necrotizing pneumonia, where bacteria destroy lung tissue. "The reason that some mild infections become severe or fatal is not well understood, but virulence is often associated with certain strains," says Jovanka Voyich, Ph.D., of RML, the study's lead author. To cause human disease, bacterial path...
