“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 know a lot of people have already responded to “If I Were A Poor Black Kid” but no one did it in quite the mocking way I’d hoped for so, as usual, I gave it a shot when I probably should have let it go. I started off angry and just became more depressed the more I broke it down. There were some possible points in his article but it’s wrapped in such stupidity and arrogance that they’re not worth delineating. __________________________________________________________________ I am not a pompous white man.Not that pompous anyway, consider me semi-pompous. So life is easier for me. But that doesn’t mean that prospects are impossible for pompous white men. I don’t believe that. I don’t believe that the pompous white man should be content with saying obnoxious things to the people in his general physical location. I believe the pompous white man should broadcast his ignorance to the far corners of the globe so that no one is in doubt. Even a poor black kid in West Philadelphia. It takes egotism. It take banality. It takes an online site dedicated to other pompous white people. It takes the help of people who should know better. It takes the arrogance to enjoy coming across as a pompous jerk who knows little about education and less about […]
Tool use in crocodylians: crocodiles and alligators use sticks as lures to attract waterbirds | Tetrapod Zoology, Scientific American Blog Network “As described by Dinets et al. (2013), Mugger crocodiles Crocodylus palustris in India and American alligators Alligator mississippiensis in the USA have both been observed to lie, partially submerged, beneath egret and heron colonies with sticks balanced across their snouts. Birds approach to collect the sticks for use in nest building and… well, let’s just say that it doesn’t end well for the birds. If the crocodylians really are using the sticks as bait to attract their bird prey, this is tool use, since the sticks are objects that are being employed for a specific function.” tags: animal crocodile tools tool science adaptation weekly How meaning comes to technology: PCR at 30 | Jean-Baptiste Gouyon | Science | theguardian.com “More than a technique, PCR is a concept, that enables molecular biologists to think in new ways of their object of study, DNA, to ask genes new questions. Opening the way to new experiments, it literally frees the imagination. Some even use PCR machines as fridges. After all a thermocycler is nothing but an intelligent heating and cooling block. It can be set on 4ºC for 48 hours, to conserve the result of an experiment over the week-end. ” How meaning […]

They will also be able to send instant alerts to other workers. The advocacy group will safeguard the information and work with lawyers to negotiate payment.” tags: app weekly sociology Posted from Diigo. The rest of my favorite links are here.
