Biohackers are mostly "amateur" molecular biologists who (often) want to make new things through genetic engineering. They have been developing their methods and on-line communities. Here is a fairly long NY Times article that gives some background and discusses different sides of regulatory issues. Currently, there is little control over what anyone who is not government funded does with these techniques. With the establishment of cheap and easy procedures that could be done at home, the production of dangerous biological entities becomes more likely. Maybe an organization of molecular biologists should make their own version of The Doomsday Clock. Actually, it turns out it should be already rolled into the current clock.
