“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.””
nonprogramistan Originally uploaded by bionicteaching Thought some of you might get a kick out of this graphic that’ll be part of a presentation Jim Groom and I are working on. The premise is that a variety of recent technologies allow the creation of mashups and other interesting web based options without the need for programming skills. Andy Warhol is the patron saint of the mashup so he adorns our poster. Original photos here.
I am still feeling my way around using Google Earth in the classroom. I want to make it more than a 3d worksheet. I think the key is making the students responsible for creating the files but I think in order to do that they need examples and exposure the program and how to use it on a more basic level. That is what this file is supposed to provide. This KMZ file covers SOLs USI 5 (for you non-Virginians that’s the early colonies in North America and some of their climate/economy/settlement rationales/religion). Download the file here. In the end I’d like to see students using it as an interactive hyper-linked notebook. If the teacher gave them a KMZ file at the start of the year and it was divided into folders based on SOLs then that’d get the organization started and the students could be responsible for adding the place marks, additional information and links out to relevant websites. I would like an internal search feature that scanned the info window text (which should be easy for Google) and I think it’d be a complete package for certain content.
cc licensed ( BY SA ) flickr photo shared by Tom Woodward I wrote this in response to Gardner’s post here and in particular this quote from Thomas Merton that Gardner referenced. “[A publisher asked me to write something on ‘The Secret of Success,’ and I refused.] If I had a message to my contemporaries, I said, it was surely this: Be anything you like, be madmen, drunks, and bastards of every shape and form, but at all costs avoid one thing: success. … If you have learned only how to be a success, your life has probably been wasted. If a university concentrates on producing successful people, it is lamentably failing in its obligation to society and to the students themselves.” On reflection, this is a bit much for a comment (so now it’s a post) and probably somewhat hyperbolic but maybe it’ll spur some interesting conversation. My response certainly sounds like a keynote (not enough gray).I’m happy to take your money for saying ridiculous things. I can also claim I give homework so you’re kids will be like the responsible farm children of yore. Just send the checks. I read it more as an indictment of the definition of “success” in a corrupt/broken system as a kind of failure rather than advocating allowing for failure as a way […]
