A pandemic influenza would mean widespread infection essentially throughout every region of the world.

The world is a place that is so interconnected that what happens in another part of the world will impact us.

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.

Investigating rare diseases gives researchers more clues about how the healthy immune system functions.

I think, collectively, we should be paying more attention to what is going on around us in the world among people who dont have the advantages that we have.

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

Activism has been very productive in our society.
