Inspired by a debate over the benefit of bicycle helmets to riders (some studies show that wearing a helmet when pedaling a bike keeps one safer, and others show the opposite), Ludmilla Carone takes on the question: What is science?

Valentines Day is long gone, but Hanno Charisius at Ein Bisschen Dunkel (A Little Bit Dark) is still getting smiles from a stash of science-themed V-day cards.
Finally, links in this article are to blog posts in German. But, generally speaking, their authors are happy to respond to comments in English.
