Scientists may have discovered a 4-quark particle...

A combination of two quark-antiquark pairs could be possible, maybe strongly interacting if they are all of similar types (charm and anti-charm in this case) or it may be via gluon exchange by the strong force.. Intriguing...

Weird...

Cooool!

Asimov's Foundation meets ACT's Tipping Point Prediction?

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.

Electron microscope studies reveal that the electron bombardment leads to polymerization of the outer layer of some insect larva's skin and protects them from dehydration. Artificial method to create this effect tested as well. Allows observation of living animals under electron microscope! Question: can the insects still breath after they are back in air? :-S

Linked to the discussion we had last week on elastically non-linear polymers. The inverted liquid->solid phase transition might be interesting and the material might be self-healing just above the transition.

In case Guido and Co. want to expand on the scent of science project... ?

Interesting research field about self-propelled particle swarms: very simple rules lead to complex behavior - in a real-world experiment!

On Android speech recognition but also with a very nice video: direct translation of English voice input to Chinese audio. Looks like it might be really useful eventually.

The algorithm that regulates the flow of ants is evolving toward minimizing operating costs rather than immediate accumulation.

Turns out even ants can profit from a siesta on a hot day and they use network security and repair mechanisms. Maybe there is still something undiscovered that we can apply for our own networks.

Nice.

I guess this is for data what oil tankers vs. pipelines are for hydrocarbons. Isn't ESA doing something similar for satellite data? I seem to remember that Leopold mentioned that at some point.

Julius von Bismarck is only 28 years old, but his artistic resume is already several pages long. He's currently taking time off from school to be the new artist in residence at CERN ? the world's biggest particle physics research facility, home of the Large Hadron Collider.

Perhaps a new role for the ACT!?

very good idea - one that already Andrés had way back and a few years ago I was in contact with a group in Amsterdam who was interested but it never materialised ... any good recommendations? this Bismark guy seems to be a nice chap to have around in the office according to the photo on the site: long beard, a bottle of wine in the office and steering out of the window in search for ideas ... give the ugly office he might even want to swap it with our nice semi open space! :-)

Autonomous sailing boat planned for setting a new record

We are living in the future when live broadcasts are being censored by AI programs in real-time. I'm sure dictators everywhere are looking forward for these technologies to mature. Having a firewall over reality is so convenient.

Oh, and look - the copyright AI doesn't likes Democrats as well: http://www.wired.com/threatlevel/2012/09/youtube-flags-democrats-convention-video-on-copyright-grounds/

What this tells is that we should not take AI seriously until smart Luis's (or his son) managed to make something decent out of it ... "This was, of course, absurd. First of all, the clips had been provided by the studios to be shown during the award ceremony. The Hugo Awards had explicit permission to broadcast them. But even if they hadn't, it is absolutely fair use to broadcast clips of copyrighted material during an award ceremony. Unfortunately, the digital restriction management (DRM) robots on Ustream had not been programmed with these basic contours of copyright law. And then, it got worse. Amid more cries of dismay on Twitter, Reddit, and elsewhere, the official Worldcon Twitter announced: Chicon 7@chicon_7 We are sorry to report that #Ustream will not resume the video feed. #chicon7 #hugos #worldcon 3 Sep 12 ReplyRetweetFavorite And with that, the broadcast was officially cut off. Dumb robots, programmed to kill any broadcast containing copyrighted material, had destroyed the only live broadcast of the Hugo Awards. Sure, we could read what was happening on Twitter, or get the official winner announcement on the Hugo website, but that is hardly the same. We wanted to see our heroes and friends on that stage, and share the event with them. In the world of science fiction writing, the Hugo Awards are kind of like the Academy Awards. Careers are made; people get dressed up and give speeches; and celebrities rub shoulders with (admittedly geeky) paparazzi. You want to see and hear it if you can. But Ustream's incorrectly programmed copyright enforcement squad had destroyed our only access. It was like a Cory Doctorow story crossed with RoboCop 2, with DRM robots going crazy and shooting indiscriminately into a crowd of perfectly innocent broadcasts."
