...[T]hese adolescent networks may be structured differently than researchers previously thought.Here's a nice graphical representation of the sexual network. (Via Boing Boing.)
The results showed that, unlike many adult networks, there was no core group of very sexually active people at the high school. There were not many students who had many partners and who provided links to the rest of the community.
Instead, the romantic and sexual network at the school created long chains of connections that spread out through the community, with few places where students directly shared the same partners with each other. But they were indirectly linked, partner to partner to partner. One component of the network linked 288 students - more than half of those who were romantically active at the school - in one long chain.

One tidbit from the article:
He confides that for a long time he figured that if an object was red, its shadow would be red too. "But I was told it wasn't," he says. But how do you know about red? He knows that there's an important visual quality to seen objects called "colour" and that it varies from object to object. He's memorised what has what colour and even which ones clash.Neuroscientists at Harvard and Boston University have been running a number of tests which show some fascinating differences from (and similarities to) the visual cortex of normal sighted people. Here's the article as well as one of his paintings. Here are more of his paintings. (Via Linkfilter.)
The systems reduce car theft, because vehicles will not start unless the system recognizes a tiny chip in the authorized key. They are used in millions of Fords, Toyotas and Nissans.More details available here, including the full academic paper (.pdf format).
All that would be required to steal a car, the researchers said, is a moment next to the car owner to extract data from the key, less than an hour of computing, and a few minutes to break in, feed the key code to the car and hot-wire it.

[Lead researcher] Rosenbloom thinks that ultra-Orthodox faith might contribute to this cavalier behaviour by making people respect religious law more than state-imposed rules. It is also possible that religious people take more risks because they are more fatalistic and have less fear of death.

1. Go to http://mappoint.msn.com/DirectionsFind.aspxInterestingly enough, if you reverse the Start and End cities, it works fine.
2. In the Start section, select "Norway" from the list box and enter "Haugesund" into the "City" field
3. In the End section, select "Norway" from the list box and enter "Trondheim" into the "City" field
4. Click on "Get Directions"...

It all sounds like a recipe for disaster. In theory, sell programs could trigger other sell programs, and cataclysm could ensue. (Program trading was partly blamed for the 1987 stock crash.) But as program trading has risen, the market counterintuitively seems to have grown less volatile. The exchanges have built in mechanisms to stop program trading from moving the market once certain limits are breached. And there's also a degree to which program trades are self-regulating. Every day, there are hundreds of different computer-driven strategies at work, and they frequently work at cross purposes. If IBM breaks through 100, it might simultaneously trigger a sell program at one hedge fund and a buy program at another.(Via Cosmic Log.)
The rise of the machines may undermine the journalists' narratives of the market. But at another level it's somewhat comforting. Program trading creates a highly unpredictable, occasionally unnerving universe in which sudden reversals can crop up out of nowhere, only to be followed by sudden outbursts of optimism. In other words, a market dominated by computerized program trades is a lot like real human life.

THE TWINKIE EXPERIMENT(Via Obscure Store.)
Notes from duplication of Rice University experiment showing that a Twinkie will explode in 45 seconds when exposed to extreme radiation:
3:30:00 p.m. Sun-Times vending room is empty. Been waiting for this chance.
3:30:28 p.m. A single standard Twinkie is unwrapped and placed in Sun-Times vending room microwave for irradiation. Setting is 100 percent. Microwave door is closed.
3:31:00 p.m. Button is pushed.
3:31:19 p.m. Twinkie appears to grow slightly in size.
3:31:22 p.m. Halfway to theoretical point of explosion, Twinkie shows no further outward signs of change.
3:31:29 p.m. A 1-inch fissure opens in top of Twinkie. White filling pours out in slow stream onto microwave's tray.
3:31:38 p.m. Flow of filling stops.
3:31:45 p.m. Theoretical point of explosion.
3:32:00 p.m. Twinkie turns darker shade of brown. Bubbles noted.
3:32:13 p.m. Twinkie turns still darker. Gone too far to stop now.
3:32:35 p.m. Twinkie ignites.
3:32:36 p.m. Black smoke fills Sun-Times vending room. Quickly take wad of wet paper towel to pick up smoking Twinkie and place under stream of cold water. Fan wildly at smoke.
3:33:00 p.m. Uneasy wait for Sun-Times sprinkler system to go off.
3:34:00 p.m. Take wad of wet paper towel out of sink. Slowly open wad to inspect Twinkie. Break Twinkie in two. More smoke billows out. Place quickly under water again.
3:35:00 p.m. Sun-Times vending room still hazy with smoke. Somebody coming down the hall. Quickly place wet Twinkie wad in wastebasket. Walk slowly out the door, nonchalant.
3:35:40 p.m. Arrive at desk in city room. Smell of burnt sugar has spread. Several colleagues comment. Continue to appear nonchalant. Too busy working to notice.
Conclusion: Do not attempt this at home. Maybe at work. But not at home.

In another uncharacteristic effort to woo the masses, Apple CEO Steve Jobs today announced that starting in February his company would ship a "starter version" of the iconic Macintosh computer which will sell for only $29 -- hardware not included.Heh heh...
The announcement follows yesterday's launch of a $499 Mac mini -- a small metal box with no monitor, keyboard, mouse, or other peripherals.
The new $29 Apple Nano-Mac promises to "reduce desktop clutter, while instilling the confidence and feelings of self-worth shared by Mac users worldwide," Mr. Jobs said.
And while critics charged that the bargain-priced Nano-Mac is "little more than a silver Apple logo sticker on an empty matchbox with no ports, plugs, peripherals or programs," Mr. Jobs was quick to point out that all of those "high-end extras can be purchased at Apple.com by users who like the Mac culture and zeitgeist and want to upgrade to a more hardware-centric experience."
