Hot Topics in Ethics?

A follow-up to the successful thread on epistemology awhile back:  what are the hot topics in ethics these days?   Moral psychology, both empirical and from the armchair, seems especially lively.  The nature of reasons too.  What else?  The more detail the better, and feel free to post links to on-line resources (papers, blog discussions, etc.).  Signed comments strongly preferred, and, as always, post only once, comments may take awhile to appear.
