“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.””
TeacherTube has been fixed for a while now and seems to be running better (in my mind anyway). It’s a great site and well worth checking out. The nice thing too, is that I imagine they’ll have locked things down pretty securely after that. It looks like TeacherTube has been hacked. Don’t try to log in or you’ll get stuck in a loop. An unnerving experience and hopefully it isn’t too bad. It does serve as a reminder to stay on guard.
The Google spreadsheet passing the information on to this chart, which should be live, is being fed by an IFTTT recipe. For the record it doesn’t seem like you can mess around with the non-used portions of the actual worksheet where data is being written by the recipe. I was able to add another worksheet and use that to run some formulas on the worksheet where the tweets are being written. =len(‘Sheet 1’!C1) is the formula you’d write to access cell C1 of Sheet 1 and count the number of characters. Granted, keeping track of my progress towards perfect 140 character tweets doesn’t have much value (although there’s one that’s 150 characters that’s a little puzzling) but it’s just a proof of concept. I could parse out other elements. I do need to look back at the DS106 hashtag spreadsheet and see how that’s working as I don’t see any working version of that since Twitter killed RSS support. And a random byproduct of some other work I’m doing messing around with The Mother of All Demos. Seriously though, tell your friends. Apply for the job.
