How an Antarctic worm makes antifreeze and what that has to do with climate change

Two BYU researchers who just returned from Antarctica are reporting a hardy worm that withstands its cold climate by cranking out antifreeze.

Year's best meteor shower and occultation of Jupiter

The Geminid meteor shower is reliably the best of the year, but you have to brave the cold of a December night to see it. So it is less well known than the Perseid shower of August, when the hazard is mosquitoes instead of frostbite. The Geminid shower will peak on the night of Dec. 13-14, just two days after the moon is new. The moon will cooperate even more by setting as the peak begins, so moonlight won't interfere at all. If clouds don't get in the way, skywatchers can expect to see 60-70 meteors per hour at the peak and perhaps more, with a number of bright ones in addition to the fainter streaks that are obscured by bright moonlight or city lights.
