Women have long battled with their biological clocks, but with men like Tony Randall cranking out kids in their seventies, many men don't really think about their biological clocks. In the wake of new studies, though, that might change. Lisa Belkin, New York Times Magazine contributing writer, makes the case in this week’s Magazine that there’s now even more evidence that when it comes to making babies, men have a sell by date.

Lisa Belkin's article will be available in the New York Times Magazine on Sunday.

Filling President-elect Barack Obama's vacant senate seat has turned into such an incredible drama that it is easy to forget that there are other empty seats in the U.S. Senate. Vice-president-elect Biden's seat was quickly filled, but more drama is roiling over the soon-to-be vacant senate seat from New York. Caroline Kennedy has made her claim on the seat once held by her father and no one is quite sure whether or not she is qualified. The coverage of that issue has raised quite a few eyebrows, too. Here to discuss all sides of the issue are Nick Confessore a reporter in the Albany bureau of the New York Times, and Lisa Belkin, a writer for the New York Times Magazine whose piece in this Sunday's magazine is called “The Senator Track.”

Read Nick Confessore's article on Ms. Kennedy in today's New York Times. (You'll have to wait for Sunday for Lisa Belkin's!)
