Sam Harris and Jerry Coyne both deny free will. Coyne believes that we do not make choices and thus, have no free will. Harris believes that we do no make choices and thus, have no free will.

I just finished posting a multi-part essay on this issue: Sam Harris and Jerry Coyne on free will:
In March 2012 AD, Sam Harris has a book coming out denying Free Will.
While I am posting a multi-part essay on Examiner about it, in the mean time, I wrote a short one for William Briggs.
In a couple of months this will become a hot topic...again ;o)
