“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.””

If you only want the highlights, here they are: grow your network by sharing, not planning to share or deciding who to share with; the tech doesn’t determine the sharing – if you want to share, you will; weave your network by sharing what you can, and they will share what they can – people won’t share [without a lot of added incentives] stuff that’s not easy or compelling for them to share. Create virtuous cycles that amplify network effects. Given the right ‘set,’ simple tech is all they need to get started.)” tags: weekly sharing Our Cubicles, Ourselves: How the Modern Office Shapes American Life – Rebecca J. Rosen – The Atlantic […]
Sea level study: James Hansen issues dire climate warning. “: Hansen’s study comes via a nontraditional publishing decision by its authors. The study will be published in Atmospheric Chemistry and Physics, an open-access “discussion” journal, and will not have formal peer review prior to its appearance online later this week. [Update, July 23: The paper is now available.] The complete discussion draft circulated to journalists was 66 pages long, and included more than 300 references. The peer review will take place in real time, with responses to the work by other scientists also published online. Hansen said this publishing timeline was necessary to make the work public as soon as possible before global negotiators meet in Paris later this year. Still, the lack of traditional peer review and the fact that this study’s results go far beyond what’s been previously published will likely bring increased scrutiny. On Twitter, Ruth Mottram, a climate scientist whose work focuses on Greenland and the Arctic, was skeptical of such enormous rates of near-term sea level rise, though she defended Hansen’s decision to publish in a nontraditional way.” tags: weekly socialmedia twitter peerreview research Rachel Berwick – may-por-é “During the attack, the Carib tribe had taken parrots which the Maypure’ people had kept as pets.

cc licensed flickr photo shared by bionicteaching Way back when, I really, really wanted to do something with this whole BattleDecks idea. Two years or so later and I finally step up to the plate. These were the rules my students got when they came in. Your group will be assigned to one of the following topics. 1. Internet safety 2. 21st century skills 3. Technology integration 4. The future of education Rules * Your presentation will last between 2 and 3 minutes * You can only choose from these 20 pictures The images were chosen fairly randomly from a selection I had taken that happened to be on my computer. I tried to pick images that were interesting and open to multiple interpretations. * You must use 10 of the provided images * You can add no more than 10 written words in the entire slide showI need to come up with a better way to say this. i had to explain it multiple times. You have 30 minutes to prepare. So it’s not exactly like the BattleDecks setup but it’s close enough and I think the rule changes made allow for more processing and a little less improv/comedy talent being necessary. The students had a lot of fun and the presentations were pretty decent. I think they’d improve […]
