How Acupuncture Pierces Chronic Pain - ScienceNOW - 0 views

  • Millions of people worldwide use acupuncture to ease a variety of painful conditions, but it’s still not clear how the ancient treatment works. Now a new study of mice shows that insertion of an acupuncture needle activates nearby pain-suppressing receptors. What’s more, a compound that boosts the response of those receptors increases pain relief—a finding that could one day lead to drugs that enhance the effectiveness of acupuncture in people.

    Good luck to them!!

    "Mathematicians Predict the Future With Data From the Past". GREAT! And physicists probably predict the past with data from the future?!? "scientists and mathematicians analyze history in the hopes of finding patterns they can then use to predict the future". Big deal! That's what any scientist does anyway... "cliodynamics"!? Give me a break!

    still, some interesting thoughts in there ... "Then you have the 50-year cycles of violence. Turchin describes these as the building up and then the release of pressure. Each time, social inequality creeps up over the decades, then reaches a breaking point. Reforms are made, but over time, those reforms are reversed, leading back to a state of increasing social inequality. The graph above shows how regular these spikes are - though there's one missing in the early 19th century, which Turchin attributes to the relative prosperity that characterized the time. He also notes that the severity of the spikes can vary depending on how governments respond to the problem. Turchin says that the United States was in a pre-revolutionary state in the 1910s, but there was a steep drop-off in violence after the 1920s because of the progressive era. The governing class made decisions to reign in corporations and allowed workers to air grievances. These policies reduced the pressure, he says, and prevented revolution. The United Kingdom was also able to avoid revolution through reforms in the 19th century, according to Turchin. But the most common way for these things to resolve themselves is through violence. Turchin takes pains to emphasize that the cycles are not the result of iron-clad rules of history, but of feedback loops - just like in ecology. "In a predator-prey cycle, such as mice and weasels or hares and lynx, the reason why populations go through periodic booms and busts has nothing to do with any external clocks," he writes. "As mice become abundant, weasels breed like crazy and multiply. Then they eat down most of the mice and starve to death themselves, at which point the few surviving mice begin breeding like crazy and the cycle repeats." There are competing theories as well. A group of researchers at the New England Complex Systems Institute - who practice a discipline called econophysics - have built their own model of political violence and

    It's not the scientific activity described in the article that is uninteresting, on the contrary! But the way it is described is just a bad joke. Once again the results itself are seemingly not sexy enough and thus something is sold as the big revolution, though it's just the application of the oldest scientific principles in a slightly different way than used before.

Apple's Mistake - 5 views

    Nice opinion piece.

    nice indeed .... especially like: "They make such great stuff, but they're such assholes. Do I really want to support this company? Should Apple care what people like me think? What difference does it make if they alienate a small minority of their users? There are a couple reasons they should care. One is that these users are the people they want as employees. If your company seems evil, the best programmers won't work for you. That hurt Microsoft a lot starting in the 90s. Programmers started to feel sheepish about working there. It seemed like selling out. When people from Microsoft were talking to other programmers and they mentioned where they worked, there were a lot of self-deprecating jokes about having gone over to the dark side. But the real problem for Microsoft wasn't the embarrassment of the people they hired. It was the people they never got. And you know who got them? Google and Apple. If Microsoft was the Empire, they were the Rebel Alliance. And it's largely because they got more of the best people that Google and Apple are doing so much better than Microsoft today. Why are programmers so fussy about their employers' morals? Partly because they can afford to be. The best programmers can work wherever they want. They don't have to work for a company they have qualms about. But the other reason programmers are fussy, I think, is that evil begets stupidity. An organization that wins by exercising power starts to lose the ability to win by doing better work. And it's not fun for a smart person to work in a place where the best ideas aren't the ones that win."

    Poor programmers can complain, but they will keep developing applications for iPhone as long as their bosses will tell them to do so... From my experience in mobile software development I assure you it's not the pain of the programmer that dictates what is done, but the customer's demand. Even though like this the quality of applications is somewhat worse than it could be, clients won't complain as they have no reference point. And things will stay as they are: apple censoring the applications, clients paying for stuff that "sometimes just does not work" (it's normal, isn't it??), and programmers complaining, but obediently making iPhone apps...

Is the staggeringly profitable business of scientific publishing bad for science? | Sci... - 2 views

    "Publishing industry exerts too much influence over what scientists choose to study, which is ultimately bad for science itself"

    On a related topic - a nice read written in 1939 from Abraham Flexner the founder of Institute for Advanced Study in Princeton, home of some great minds on the "Usefulness of Useless Knowledge". Enjoy https://library.ias.edu/files/UsefulnessHarpers.pdf

    This article is fantastic - starts already well with : "r IT not a curious fact that in a world steeped in irrational hatreds which threaten civilization itself, men and women-old and young-detach them-selves wholly or partly from the angry current of daily life to devote themselves to the cultivation ofbeauty, to the exten-sion ofknowledge, to the cure ofdisease, to the amelioration of suffering, just as though fanatics were not simultaneously engaged in spreading pain, ugliness, and suffering?"
