The continued occupation of Iraq costs this nation at least $16m every hour.
The above is a cool article because it suggests that adult neurogenesis has the potential for clinical application. Not that it hasn’t been suggested elsewhere, but this is one of the more promising approaches.

It’s kind of surprising that it was only demonstrated in 2007 that humans have an RMS (i.e. we generate new olfactory neurons). Adult neurogenesis in both the SVZ (destined for the olfactory bulb) and the SGZ (destined for the dentate gyrus of the hippocampus), though especially the latter, has been linked in numerous studies to memory and learning.
