The topic of the week for Tuesday the 5th will be Embryonic Stem Cell Research, which should tie in well (pretty much directly) with what we've been learning in class.
For the most recent developments in the current litigation involving the research, see this brief article from the Nature blog. Nature also has a succinct history of the current legal scuffle here, as well as an entire section devoted to coverage of the stem cell injunction here.
I'd like to highlight the Opinion section of the previous link, where the editorial staff makes a plea to save stem cell research here, and the lawyer in charge of the plaintiff's case directly responds here.
Lastly (for now), this article captures the sentiment of those opposing embryonic stem cell research fairly well.
