Mice have been given "night vision" by injecting nano particles into their eyeballs. This works in the near infrared and persists for some 10 weeks. Rumor has it it helps red color blindness as well.
Also we now have yeasts that produce the cannaboids (sp?) found in pot. Not only that but there are a bunch of these and depending on how you treat the yeasts, you can get all the ones we know about and some we haven't seen before. No telling what the new ones do but there's a near limitless supply of hippies out there who will happily volunteer to try the stuff and tell you what happened.
One company says it has modified yeasts to produce opioids as well which would have a major impact on the drug biz as opium and its relatives might now be produced directly in beer brewing carboys in peoples basements, eliminating the growing and shipping business which accounts for most of the expense of production.
