Synthetic Biology is an interesting site about the branch of science informally described as "[m]aking life better, one part at a time" or more formally:

A) the design and construction of new biological parts, devices, and systems, and
B) the re-design of existing, natural biological systems for useful purposes.

Whether one believes that reverse engineering and re-designing organisms is a worthwhile goal, it is certainly the holy grail for a biohacker. The site looks like an excellent resource for someone deciding whether they want to join the field.
