Researchers spy on BitTorrent users in real-time • The Register
www.theregister.co.uk/2010/04/30/bittorrent_continuous_spying/, posted 2010 by peter in communication distributed msm networking p2p privacy science
In a paper presented earlier this week at the Usenix Workshop on Large-Scale Exploits and Emergent Threats, the researchers demonstrated how they used the technique to continuously spy on BitTorrent users for 103 days. They collected 148 million IP addresses and identified 2 billion copies of downloads, many of them copyrighted.
The researchers, from the French National Institute for Research in Computer Science and Control, also identified the IP addresses where much of the content originated. They discovered the the vast majority of the material on BitTorrent started with a relatively small number of individuals.

Why We Can't Do 3 Things at Once | LiveScience
www.livescience.com/health/brain-multitasking-limit-100415.html, posted 2010 by peter in cognition msm science toread
For those who find it tough to juggle more than a couple things at once, don't despair. The brain is set up to manage two tasks, but not more, a new study suggests.
That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled.

Japanese researchers successfully complete artificial eel cultivation cycle

Sankei News reported that in 1957 approximately 207 tons of small eel were caught, but by 2008 that number had dropped to just nine tons. Beyond that, attempts at farm breeding the animal have not been successful worldwide.
In response, scientists at the Fisheries Research Agency began studying artificial breeding methods.
By 2002 the Agency had accomplished artificially fertilizing and incubating eel eggs. The Agency has also had success in raising eel larvae to maturity.

Japanese Guts Are Made for Sushi - ScienceNOW

Americans don't have the guts for sushi. At least that's the implication of a new study, which finds that Japanese people harbor enzymes in their intestinal bacteria that help them digest seaweed--enzymes that North Americans lack. What's more, Japanese may have first acquired these enzymes by eating bacteria that thrive on seaweed in the open ocean.

James Lovelock: Humans are too stupid to prevent climate change | Environment | The Guardian

Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades. This is the stark conclusion of James Lovelock, the globally respected environmental thinker and independent scientist who developed the Gaia theory.
...
"I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change," said Lovelock in his first in-depth interview since the theft of the UEA emails last November. "The inertia of humans is so huge that you can't really do anything meaningful."
One of the main obstructions to meaningful action is "modern democracy", he added. "Even the best democracies agree that when a major war approaches, democracy must be put on hold for the time being. I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while."

Alice's adventures in algebra: Wonderland solved - physics-math - 16 December 2009 - New Scientist
www.newscientist.com/article/mg20427391.600-alices-adventures-in-algebra-wonderland-solved.html?full=true, posted 2010 by peter in fiction literature math philosophy science
The 19th century was a turbulent time for mathematics, with many new and controversial concepts, like imaginary numbers, becoming widely accepted in the mathematical community. Putting Alice's Adventures in Wonderland in this context, it becomes clear that Dodgson, a stubbornly conservative mathematician, used some of the missing scenes to satirise these radical new ideas.

No moment in technology history has ever been more exciting or dangerous than now. The Internet is like a new computer running a flashy, exciting demo. We have been entranced by this demo for fifteen years. But now it is time to get to work, and make the Internet do what we want it to.
-- DAVID GELERNTER is a professor of computer science at Yale and chief scientist at Mirror Worlds Technologies (New Haven). His research centers on information management, parallel programming, and artificial intelligence. The "tuple spaces" introduced in Nicholas Carriero and Gelernter's Linda system (1983) are the basis of many computer communication systems worldwide. He is the author of Mirror Worlds, and Drawing a Life: Surviving the Unabomber.

Den vetenskapliga analfabetismen är ett hot mot demokratin, anser författarna till »Unscientific America«.

Författarna menar att USA drabbats av en ny sorts analfabetism. Flumläror tillåts härja fritt, stöttade av reaktionära krafter. Samtidigt dalar vetenskapsjournalistiken – och forskarna tiger.

Belief In Climate Change Hinges On Worldview : NPR

o social scientist and lawyer Don Braman, it's not surprising that two people can disagree so strongly over science. Braman is on the faculty at George Washington University and part of The Cultural Cognition Project, a group of scholars who study how cultural values shape public perceptions and policy beliefs.
"People tend to conform their factual beliefs to ones that are consistent with their cultural outlook, their world view," Braman says.

The optical appearance of the stellar sky for an observer in the vicinity of a black hole is dominated by bending of light, frequency shift, and magnification caused by gravitational lensing and aberration. Due to the finite apperture of an observer's eye or a telescope, Fraunhofer diffraction has to be taken into account. Using todays high performance graphics hardware, we have developed a Qt application which enables the user to interactively explore the stellar sky in the vicinity of a Schwarzschild black hole. For that, we determine what an observer, who can either move quasistatically around the black hole or follow a timelike radial geodesic, would actually see.
