It's science!

Been busy over the last two days, so it's time to catch up. Some science picks from the latter part of this week:

• Nagging spouse? You may have an excuse for not responding -- No, dear, I'm not consciously aware of the fact that I'm ignoring you.
• West African chimpanzees have been cracking nuts with stone tools for thousands of years -- I, for one, welcome our new simian overlords. Check out this related article for pictures.
• Why we see faces when they're not really there -- That still looks like a grilled cheese sandwich to me. (Oh, and using Exposé to figure out the pixelated images is considered cheating.)
• Voracious deep-sea squid -- That is a lot of friggin' calamari.
• Have you heard about B-flat? -- Strange tales of tubas, alligators, and black holes.
• Artificial intelligence may answer some key questions about insect flight -- Tiny flying things measure speed and altitude using "optic flow" (definitely not FAA approved); personally, I'll stick with the standard six.
