“Dr. SkySkull” selects several notable posts each week from a miscellany of ResearchBlogging.org categories. He blogs at Skulls in the Stars.

Sorry for a late batch of selections this week!

• There are more things in heaven and earth, cobber, than are dreamt of in your philosophy. There’s more to studying the history of astronomy than awarding marks for scientific achievements! Alun at AlunSalt discusses this idea in the context of how Australian Aboriginal people viewed and view astronomy.
• CO2 is the biggest climate control knob. Recent research suggests that CO2 plays a bigger role in climate change than previously thought, producing even more dramatic effects — especially on the colder end of the scale! Phil Camill of Global Change: Intersection of Nature and Culture gives the details.
• The @#$% 2010 Ig Nobel Peace Prize: Pain files 1. The IgNobels have been a great source of fascinating research this year! Greg Downey of Neuroanthropology describes research that suggests that swearing really does make the pain feel better!

Finally, just when you couldn’t imagine that Tyrannosaurus rex couldn’t get any more intimidating, comes strong evidence that the creature was also a cannibal when it needed to be! We look at two different accounts of the research: Tyrannosaurus the Cannibal, by Brian Switek at Dinosaur Tracking, and When Tyrannosauraus rex had for breakfast… another Tyrannosaurus rex by Rogue at Into Oblivion.

Check back next Monday for more miscellaneous selections!
