“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.””
I listened to Net@Nite today. They interviewed Jimmy Wales of Wikipedia and it was pretty interesting but had nothing to do with education. That did not stop me from applying some of these quotes directly to what we do. “This idea of- it’s not really about the software, it’s about the people. It’s about helping people find resolutions to problems and being supportive and loving and at the same time being firm with people who are trying to disrupt things. That’s really what it’s all about.” – Jimmy Wales “Ask anyone who’s every tried this. This is a very difficult balance to strike.”- Leo Laporte Leo’s preaching to the choir here. That line is very hard to walk and it sounds an awful lot like good classroom management- but with voluntary students. I always wondered would my students stay if they didn’t have to. Did I make their experience that good? Sometimes I did. I know I also failed at times and that’s where the next quote came in- “A long term project of learning, experimenting, you know trying things.” – Jimmy Wales To me that’s teaching. A long term project of learning, experimenting and trying things. If you aren’t changing and experimenting and learning right along with your students something is wrong. Several of my disaster lessons led to […]
Hitchhiking robot’s cross-country trip in US ends in Philly “With the robot destroyed, Zeller said, she was most concerned about children who loved hitchBOT and followed it on social media.
