The worst potential bio-terrorist is nature itself.

We feel confident that there won't be an outbreak.

Exposures, if they are mild, in the sense of barely just a small concentration, it's mostly an irritant, particularly the peroxides, that in that smoke would irritate the skin or even irritate the lungs. So, for the most time, it could be either just a little bit of a nuisance irritant, or if you get a really big whiff of it, particularly people who have, for example, reversible airways disease, like asthma or different types of hypersensitivity diseases, you could get a serious problem.

Certainly the support for research in HIV/AIDS was good in the Clinton administration, good in the Bush administrations. It just was.

An AIDS-free generation would mean that virtually no child is born with HIV; that, as those children grow up, their risk of becoming infected is far lower than it is today; and that those who become infected can access treatment to help prevent them from developing AIDS and from passing the virus on to others.

Better ways to diagnose, treat and prevent E. coli 0157:H7 infections are badly needed.

I run a modest-sized laboratory thats looking specifically at what we call the pathogenic mechanisms of HIV disease, or AIDS.
