“It’s all quite nuttily modern. Wired Love anticipates everything we live with in today’s online, Iphoned courtship: Assessing whether someone you’ve met online is what they say they are; the misunderstandings of tone and substance that come from communicating in rapid-fire, conversational bursts of text; or even the fact that you might not really be sure of the gender/nationality/species of the person you’re flirting with.
Total Recall for mice. Arnold’s nightmares are now becoming possible.
“Memories can be unreliable. We created a false memory in mice by optogenetically manipulating memory engram–bearing cells in the hippocampus. Dentate gyrus (DG) or CA1 neurons activated by exposure to a particular context were labeled with channelrhodopsin-2. These neurons were later optically reactivated during fear conditioning in a different context. The DG experimental group showed increased freezing in the original context, in which a foot shock was never delivered. The recall of this false memory was context-specific, activated similar downstream regions engaged during natural fear memory recall, and was also capable of driving an active fear response. Our data demonstrate that it is possible to generate an internally represented and behaviorally expressed fear memory via artificial means.
“I’ve been fascinated recently by how much of our natural history consists of similar barely-substantiated claims that have only been recently tested. Some turn out to be true, like the cheetah’s speed or the function of the thresher shark’s tail. Others are myths, like the cheetah’s heat problems, or the komodo dragon’s bacterial bite (they use venom), or the honey badger’s partnership with honey guides (deceitful documentary-makers), or the suicidal tendencies of lemmings (deceitful film-makers). One wonders what other myths will be busted in coming years.”
“The city of Detroit applied for bankruptcy, citing $18.5 billion in debt owed to approximately 100,000 creditors, among them municipal bondholders and pension-plan members. “After this little kerfuffle,” said emergency manager Kevyn Orr, “we’ll be back in business.””
“”That includes following Twitter,” said a source at the penitentiary, referring to Pope Francis’ Twitter account, which has gathered seven million followers. “But you must be following the events live. It is not as if you can get an indulgence by chatting on the internet.””
Image by David Kernohan animation by Michael Branson Smith. I’m attending ELI 2014. MOOC seems to be synonymous with any online or blended “educational” offering regardless of size or openness. That’s a pretty open definition. Massive Massive (or massively) is a strange word to ignore. It is the first letter after all. It seems important to differentiate between online courses which have lots of participants and courses which use massive participation to change course possibilities. If a student can’t tellPress releases don’t count. if they’re the only student in the course or if there are 5,000Number picked as a random big number. I’m not sure when a class moves from regular to big to massive. I imagine it depends. other students, you just have an online course. Please retract your media statements before the old school online learning people burn you in effigy. If you take your 5,000 students and break them down so they are in “normal” sized cohorts that proceed independently, congratulations you have several online courses. Please call your mom and tell her you might have overstated your MOOC street cred. If having 5,000 students actually hurts your students, you have an online mess. Punish yourself by reading YouTube comments until you lose hope in humanity. Massiveness should matter, otherwise what’s the point? It needs to be […]

How does fear manifest in space? High walls. No windows. Closed spaces. By extracting management from the doers and makers of the company, there’s plausible deniability. When conversation is inhibited by high-walled cubicles, information is controlled. And to effectively instill fear in office culture, you have to control information. You have to make sure teams are segmented into departments, information is transmitted linearly and power is centralized.” tags: spaces learning office design weekly Posted from Diigo.

Thus the term anechoic: no echo. It’s so quiet, you can hear your own organs: your heart, stomach, even your ears, which make a tiny amount of noise. It turns out that it’s not an especially pleasant experience, especially in the dark. The longest anyone has ever spent alone in the chamber?
