The Burroughs Wellcome Career Awards at the Scientific Interface have opened back up! This is a transitional award similar to the R00. While you can only apply as a postdoc, it doesn't provide postdoctoral funding support (as far as I am aware). However it does provide $500K (total) of support over three years to bring with you to a faculty position. It's less money overall than the K99/R00, and also extremely competitive, but anyone here whose work is relevant and who is submitting a K99 proposal might as well adapt it to apply to this program, too! Here is the link:
I know a couple of people who have gotten or almost gotten these, and they are really nice awards--just more susceptible to changes in the market and the economy than the NIH (they didn't even have a competition last year as far as I know, their funds were way down because of the recession).
