Morsels for the mind – 9/8/2013
Every day we provide you with #SixIncredibleThingsBeforeBreakfast to nibble away at. Here you can fill your brain with the most intellectually stimulating “amuse bouches” from the past week – a veritable smorgasbord for the cranium. They’re all here for you to load up your plate – this week’s “Morsels for the mind”. Enjoy!
Feather, fur & fin – birds, beasts, fishes, and the things they do
This week was shark week. Unfortunately, the week was marred by the scientific equivalent of “jumping the shark”. Faux science packaged as the real deal. It may have reeled in viewers, but the net effect was bad. This topic was perfectly covered by Christie Wilcox, Devon Maloney, John Platt, Darren Naish, Matt Bonnan, and Alex Warneke. As an antidote to the foe of faux, great real shark science was provided by Meghan Balk and Catalina Pimiento, Ed Yong, Craig McLain, and Hannah Waters.
