Just to clarify:

The previous link I posted was not the one referenced in the Science Daily. That would be here:

http://doi.wiley.com/10.1002/emmm.201200245

Unfortunately, all of these original articles are behind a paywall. Most of us here have some University access, I believe, but not all. Science Daily at leasts gets you the gist.

Not I... It's been 13 years since I've had easy access to academic papers.
