Okay, technically I'm probably calling this one as a win to early - it hasn't been tested on human's yet. In Nature, we have an article on a group from China that have made transgenic rice that produces human serum albumin, a protein out of out blood. At the moment it's mostly taken from blood donations. So having a supply that we can literally grow is going to break open a supply bottle neck. It has a variety of uses and one of it's big plusses will be infection free. It's only been tested on mice so far, but it appears to be chemically identical to naturally derived human serum albumin so far. Fingers crossed.
Even if it doesn't work, it's still a win though. Just the fact that we are thinking about doing stuff like this is incredibly cool. And there's cooler stuff yet to come.
