Tool use in crocodylians: crocodiles and alligators use sticks as lures to attract waterbirds | Tetrapod Zoology, Scientific American Blog Network “As described by Dinets et al. (2013), Mugger crocodiles Crocodylus palustris in India and American alligators Alligator mississippiensis in the USA have both been observed to lie, partially submerged, beneath egret and heron colonies with sticks balanced across their snouts. Birds approach to collect the sticks for use in nest building and… well, let’s just say that it doesn’t end well for the birds. If the crocodylians really are using the sticks as bait to attract their bird prey, this is tool use, since the sticks are objects that are being employed for a specific function.” tags: animal crocodile tools tool science adaptation weekly How meaning comes to technology: PCR at 30 | Jean-Baptiste Gouyon | Science | theguardian.com “More than a technique, PCR is a concept, that enables molecular biologists to think in new ways of their object of study, DNA, to ask genes new questions.

I’m obviously not originating this idea but I’d like to advance it some more. One of the worst things you can do is force people who don’t feel pain to take your aspirin. They may oblige you if you have some particular kind of authority in their lives but that aspirin will feel pointless. It’ll undermine their respect for medicine in general.” tags: weekly itch headache urge math dydan meyer question force Lessons from the principal of a Kentucky school that went from one of the worst to one of the best under Common Core – The Hechinger Report Like the SBG stuff from Shawn Cornally (think, thank, thunk).

Why? Twitter, at the urging of the US government, has been shutting down the accounts of ISIS supporters for months. So, ISIS supporters responded by making a threat with a nifty graphic: We told you from the beginning it’s not your war, but you didn’t get it and kept closing our accounts on Twitter, but we always come back. But when […]
