The DIY bio trend goes one giant step beyond those home chemistry kits you got as a kid, even if you got them before they moved the "fun" chemicals out. Amateurs are running gel setups in their kitchens, splicing genes into e. coli, and custom designing yeast. There's the usual air of media panic about this whole thing (e.g., "what if they create ebola at home?") and overhype ("who is the next Bill Gates?"), but biohacking has enormous promise for doing interesting and valuable research, plus, it's fun.
