Unexplained space in Chrome?

I've got extra whitespace chrome, but no other browser on my client's website healthimpactnews.com. There is excess white space in two spots (the promo at the top, and the bottom portion of the slider below).

I've looked through the css... and I ca开发者_如何学Cn't figure out what's causing this. Any ideas?

The content of the div is aligned to bottom and, therefore, lines up inaccurately with the top. I changed the alignment to top. No problems now.
