Introducing hourglass, a blog carnival

With the ever expanding horizon of the blogosphere it becomes more and more difficult to find and appreciate the vast amount of excellent posts pertinent to your favorite topic. Blog carnivals are a possibility to aggregate and distribute noteworthy postings and also bring less well known blogs into the light. As a commemoration of already two years of engaged blogging on biogerontology topics Ouroboros brings us a brand new carnival... the hourglass. Highly recommended reading.
