“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.””
Ruminations from the Test-Prep Industry: How Dare You? Or: Supply, Demand, and Diatribe. “What I think but don’t say is that we “dare” charge what we do because a critical mass of people are willing to pay that much. As someone who thinks capitalism is on the whole pretty icky, it makes a definite amount of sense to me that if what we’re offering is essentially a luxury service, we would charge as much as people are willing to pay. If what we’re offering isn’t food or water or medicine or a foundational education (which, don’t get me started), as long as it’s a sidecar, an add-on, an optional addition to those necessities, why shouldn’t we charge what people will pay, so long as they’re happy with the results? And then I cringe, listening to my own thoughts.” tags: weekly test prep capitalism essential supply demand TCS – Robot Heart: Heart-Shaped Box – Nirvana (covered by Kawehi) – YouTube I don’t know how I feel about the song but the way it all works technically is pretty fascinating. tags: music loops technology weekly youtube video Thomas Christiansen on Learning from 60,000 Observations | Quantified SelfQuantified Self “It’s an iterative process.

I’m leaving Mojang | notch.net “I don’t see myself as a real game developer. I make games because it’s fun, and because I love games and I love to program, but I don’t make games with the intention of them becoming huge hits, and I don’t try to change the world. Minecraft certainly became a huge hit, and people are telling me it’s changed games. I never meant for it to do either. It’s certainly flattering, and to gradually get thrust into some kind of public spotlight is interesting. “ tags: weekly minecraft game leaving New Statesman | Why the cult of hard work is counter-productive “As Samuel Johnson once wrote: “Some are always in a state of preparation, occupied in previous measures, forming plans, accumulating materials and providing for the main affair.

Explorable Explanations “Do & Show & Tell Don’t try to explain everything with something interactive. Use interactivity only when interactivity works best, otherwise, supplement it with text & images. Also keep in mind the overlaps of Do & Show & Tell: when text interacts with the diagrams (e.g. Tangle), and vice versa. Text: Best at describing very abstract concepts. Graphs: Best at showing broad relationships at a glance. Animations: Best at showing temporal relationships. Interactives: Best at showing processes, systems, models.
