Wired magazine has a gallery containing images from the nanoworld with a little description of each image.

It is really important and fun to explore smaller worlds that the human eye can't see. That's what makes Immunology and Quantum Physics so cool. Worth checking out: http://www.wired.com/science/discoveries/multimedia/2008/02/nano_gallery_jmm?slide=1&slideView=10

British scientists have discovered a way to turn female bone marrow into sperm, which makes our species capable of surviving without males! One more factor that takes males out of scope is that newborns are only females, due to the lack of the Y chromosome in females (females are XX while males are XY). However, the method does not guarantee a birth without defects, and so it's not the right time to put men out of the shelf of evolution. In fact, for ages to come, this would still not be possible as it's not a process of 'natural' selection.
