While I've certainly heard about this happening, I'd never seen it before, and immediately it made me wonder about this octopus' decision to pull itself along mantle-first. I'd always expected that one would do the pulling with one's legs, and drag the big mantle behind, but watching this, it makes me think: "Well, that makes sense... when an octopus escapes in the water, it scoots itself along with the mantle in front, so perhaps it takes the same approach when escaping from predators on land." Maybe when they take over the world, they'll figure out that it's easier to go legs-first...
In any event, that led to a link to SciAm's new cephaloblog, The Octopus Chronicles, which sets out to catalog all the wicked cool stuff going on in current research around octopuses. They have a great little bit about the new discovery of camouflage adaptations in mesopelagic octopuses. (I especially liked the idea that these little guys' response to detection, indicated by persistent blue light, was to hide their heads inside their bodies... reminds me of one time when I was trying to avoid getting in trouble by hiding behind a tree while wearing a bright red jacket. Ineffectual, to say the least. But I digress...)
Fortunately, SciAm's page had a link to a new video produced by NASA and the International Space Station. I had heard that a good number of our astronauts were not only super-driven, super-nerdy and super-lucky, but also pretty good photographers. What I didn't know is that some of them are really good photographers, with a penchant for time-lapse videos like this one (fullscreen HD is a must):
#fromspace was a literal hashtag?) and even video podcasts (Hehe... "Open the podcast bay doors, HAL"), our scientists in the thermosphere are working hard to connect us groundlings with the things one can learn from floating about the world at around 225 miles up:
