Magic Monday and science talk comes once again. Today is the time to gather around and take a well deserved hiatus from all the politics of the day. New discoveries, new takes on old knowledge, and other bits of news are all available for the perusing in today's information world. Over the fold are selections from the past week from a few of the many excellent science news sites around the world. Today's tidbits include for platinum catalysts smaller may be better, the effect of competition in disturbed ecosystems, 2-billion-year-old fossils may be earliest multicellular life, nitrogen pollution alters global change from the ground up, saber tooth tigers also had strong forelimbs, oil spills may raise arsenic levels in the ocean, and melting ice allows a new realm for archeology. Pull up that beach chair and settle in for one more session of Dr. Possum's science education and entertainment.
