A week has passed since the terrorist attack on a natural gas facility in Algeria, but risk analysts and security experts are still undecided about the incident's likely impact in the energy world.
The price of oil, a good indicator of anxiety in the energy market, went up modestly right after the attack, but then it stabilized.

It all started with two men in a pub. Ewan Birney and Nick Goldman, both scientists from the European Bioinformatics Institute, were drinking beer and discussing a problem.
At 72, the prince of R&B has reverted to childhood. Aaron Neville has a new album called My True Story, and it's a collection of the songs he sang growing up in the projects of New Orleans in the 1950s and '60s, back when doo-wop was king.

And now for some reaction to that decision, we turn to Anne Coughlin. She's a professor at the University of Virginia Law School, and her research inspired a lawsuit brought by two women in the Army Reserve seeking to reverse that ban.

ANNE COUGHLIN: Thank you so much, Melissa. I'm happy to be here.
BLOCK: And first, your thoughts when you heard this decision from Secretary Panetta today.
