As always, plenty of interesting stuff.  What struck my interest in this week’s Science Magazine:

Mars stuff!! Nasa Curiosity rover hits organic pay dirt on Mars (News/summary section), Organic molecules on Mars (insights), Background levels of methane in Mars’ atmosphere show strong seasonal variations (neat, and so tantalizing!), Organic matter preserved in 3-billion-year-old mudstones at Gale crater, Mars.

Bees understand zero!?!? WOW!  What a cool experimental design and interesting result!  Numerical ordering of zero in honey bees.  (“Bees demonstrated an understanding that parallels animals such as the African grey parrot, nonhuman primates, and even preschool children”)

Bonus: I have tracked male/female ratios in obituaries – something I take note of when I’m looking through.  I’ve started to write down and share.  This weeks obits in Science: 1 male, 0 female.
