I mentioned a while ago that I'm involved in the Pint of Scientist festival this year. Handling the "Life sciences" section in Bristol (book your tickets now).
I know I have readers from other parts of the world and the website now has sections for USA, France, Australia and Switzerland. So if you live in any of those countries have a click and see what may be on in your area.
I'll try and do some more shameless promotion for the talks I'm involved in although I should probably concentrate on making sure they run smoothly first!
