What is evolution? New book from U.S. National Academy of Sciences explains it well.

The new book is geared toward explaining evolution to the American public.   Here's a pdf brochure describing the book.  The book can also be read online in its entirety here.

“The surge is working.” Well, yes and no.

Bush supporters, including some Republican presidential candidates, have been boasting lately that Bush's troop surge in Iraq last year is "working."  However, for several reasons, this claim is highly dubious.  First, there never were any clear goals stated for the surge, nor was any timetable ever given, so there actually is no…
