Drs. Aron J. Cohen, Paula Mori-Sánchez and Weitao Yang just published a perspective in Science entitled "Insights into Current Limitations of Density Functional Theory", (http://www.sciencemag.org/cgi/content/full/321/5890/792). It provides insights on the the main failures of density functional approximations and offers path forward to overcome the challenges.

Speaking of Dr. Cohen, Aron will launch his independent career in the late fall of 2008 at Cambridge University in the United Kingdom with a prestigeous Royal Society Research Fellowship. Congratulations!
