Another 'Best of' List...

MIT's Technology Review rounds up the latest and most publicized advances in biotech in 2007. You've heard it before (in fact, last week's issue of Science goes into similarly researched breakthroughs of the year), but personal genomics, genetic variation and creating stem cells without using embryos, of course, all made it on their list.
