“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.””

In it, Felder describes his students grumbling that they hated group work and that it was his job to teach them, not the other way around. Holman’s students said the complaints sounded like they came from kindergarteners or themselves and were amazed to find out the complainers were graduate level engineering students. “ tags: sbg teaching education weekly 5 Instagram Tips for Science Artists – Symbiartic – Scientific American Blog Network “Here are my five tips for science artists on Instagram.” “Go hashtag crazy.” tags: science artists instagram tips weekly Disinformation Visualization: How to lie with datavis | Visualising Information for Advocacy “But all maps lie.

When a young boy wanted to learn to hunt lions he didn’t read the instruction manual, nor did he take a class. Throughout human history we have learned by watching someone older than ourselves, trying to copy that person, trying to be part of the team, and then trying things for yourself, and asking for help when we have […]
Mr. Guhlin asked “How have laptop programs helped?” and the responses depressed me. Maybe, I’m over analyzing but quote like “Imagine anything one could do on an overhead projector. You can do the same on a tablet if you have an LCD.” brought me close to tears. Clearly, replacing an overhead and pen with several thousands of dollars worth of equipment to do “the same” is not a cost efficient trade. Other quotes that made me wince: my laptop/tablet has replaced a paper notebook during meetings. Have students do grammar exercises. Math teachers do the same. Not exactly what you’d want to hear if you’re paying for those laptops. Now, I also realize these are quick reports but I don’t see anything in there about students doing anything they couldn’t do with paper for far less money.Â The whole point of a 1:1 is to get students producing with laptops and to have no comment on that worries me. Don’t get me wrong- I’m for 1:1 initiatives and that’s why I’m concerned. I work in a district going on the 6th year of a 1:1 initiative and I worry that some teachers might give similar “proof” that our program is working. So here’s how our 1:1 has helped students in our school- everyone now has a computer no matter their […]
