Hi Guys,
Check out this paper
http://www.sciencemag.org/content/335/6070/831.short
Unless I'm mistaken, this paper seems to suggest a solution to the
main problem that bothered us in the previous paper - how to pack
biological machinery so it does not have undesirable interactions with
the body.
Also, it might be a nice a paper to discuss next time if you want.
Cheers,
Daniel
