(University of North Carolina at Chapel Hill) In the budding field of nanotechnology, scientists already know that size does matter.

But now, researchers at the University of North Carolina at Chapel Hill have shown that shape matters even more -- a finding that could lead to new and more effective methods for treating cancer and other diseases, from diabetes and multiple sclerosis to arthritis and obesity.
