Cheap cars allow Indians to jump off motorcycles MUMBAI (AFP) - Trading a motorcycle for a car in India has long been too expensive for many, but manufacturers plan to offer models at 3,000 dollars or less to attract new buyers, analysts say. The push by Nissan Renault, Tata Motors and Global Automobiles -- a subsidiary of the Kolkata-based Xenitis group and China's Guangzhou Motors -- comes as car sales in India fell in April and May to a combined 1.52 million from 1.6 million a year earlier. It was the first back-to-back monthly decline in three years, a period of annual double-digit growth. But a new sales strategy is about to be unleashed. "TataÂ’s small car is ...

Rising sea levels could divide and conquer Antarctic ice EARTH'S largest ice sheet has till now seemed well able to withstand the effects of climate change, but it may have a hidden weakness. While models predict the air over the East Antarctic ice sheet will remain chilly enough to prevent significant melting for at least a century, a new study suggests that rising sea levels - caused by melting elsewhere - could be its undoing (Geology, vol 35, p 551). A team led by Andrew Mackintosh at Victoria University of Wellington, New Zealand, gauged the ice sheet's past thickness by measuring how high the ice had deposited boulders in Antarctica's Framnes mountains during a period ...
Amazon Longer Than Nile River, Scientists Say

The Amazon River, not the Nile, is the longest in the world, a team of Brazilian scientists claims. The scientists claim to have traced the river's source to a snow-capped mountain in southern Peru, adding a new twist in the swirling debate over the longest river label. (See a map of the region.) The Amazon is considered the world's largest river by volume, but scientists have believed it is slightly shorter than Africa's Nile. The Brazilian scientists' 14-day expedition extended the Amazon's length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile. According to the team's results, which have not been published, the ...

The K7RA Solar Update June 23-24 is ARRL Field Day, and it follows a week with no sunspots. As expected, there was a mild geomagnetic upset on Thursday, June 21 when a solar wind stream pushed against Earth's magnetic field. The planetary A index went to 14, a moderate level, but the mid-latitude A index, which affects most of us more directly, was only 8. That number comes from the Fredericksburg Geomagnetic Center near Corbin, Virginia, which is at 38.2 degrees north latitude. Boulder, Colorado provides the mid-latitude A index that we hear on WWV at 18 minutes after each hour, and at 40 degrees north latitude, it produced an A index of 12 for June 21. For the weekend, we might see ...

Firstborns found to have higher intelligence A study of 240,000 Norwegian men says eldest children have IQs 2 to 3 points greater than younger siblings'. By Denise Gellene, Times Staff Writer June 22, 2007 Wading into an age-old debate, researchers have found that firstborn children are smarter than their siblings — and the reason is not genetics, but the way their parents treat them, according to a study published today. The study of 240,000 Norwegian men in the journal Science found the IQs of firstborns were 2 to 3 points higher than that of younger siblings. (The average IQ is 100.) Though that may not sound like a lot, experts said even a few IQ points could make a big ...

In the 1970s, leading scientists claimed that the world was threatened by an era of global cooling. Based on what we've learned this decade, says George Kukla, those scientists - and he was among them -- had it right. The world is about to enter another Ice Age. Dr. Kukla, in 1972 a member of the Czechoslovakian Academy of Sciences and a pioneer in the field of astronomical forcing, became a central figure in convincing the United States government to take the dangers of climate change seriously. In January of that year, he and another geologist, Robert Matthews of Brown University, convened what would become a historic conference of top European and American investigators in ...

RENOWNED British scientist Sir Isaac Newton, the father of modern physics and astronomy, predicted the world would end in 2060 in a 1704 letter that went on show in Jerusalem today. A famed rationalist, who secured a royal exemption so that he would not have to follow the teachings of the Church of England, Newton nonetheless based his prediction on a Biblical text. Working from verses in the Book of Daniel, the elaborator of the classical laws of gravity, motion and optics argued that the world would end 1260 years after the foundation of the Holy Roman Empire in western Europe in 800 AD. The letter, on show at Jerusalem's Hebrew University as part of an exhibition entitled ...

June 19, 2007 Millions of Missing Birds, Vanishing in Plain Sight By VERLYN KLINKENBORG Last week, the Audubon Society released a new report describing the sharp and startling population decline of some of the most familiar and common birds in America: several kinds of sparrows, the Northern bobwhite, the Eastern meadowlark, the common grackle and the common tern. The average decline of the 20 species in the Audubon Society’s report is 68 percent. Forty years ago, there were an estimated 31 million bobwhites. Now there are 5.5 million. Compared to the hundred-some condors presently in the wild, 5.5 million bobwhites sounds like a lot of birds. But what matters is the 25.5 million ...

TIMOTHY PATTERSON, Financial Post Politicians and environmentalists these days convey the impression that climate-change research is an exceptionally dull field with little left to discover. We are assured by everyone from David Suzuki to Al Gore to Prime Minister Stephen Harper that "the science is settled." At the recent G8 summit, German Chancellor Angela Merkel even attempted to convince world leaders to play God by restricting carbon-dioxide emissions to a level that would magically limit the rise in world ...

see video here This is a solid-state Tesla coil. The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear. What's not immediately obvious in this video is how loud this is. Many people were covering their ears, dogs were barking. In the sections where the crowd is cheering and the coils is starting and stopping, you can hear the the crowd is drowned out by the coil when it's firing.

Local scientist calls global warming theory 'hooey' Samara Kalk Derby — 6/18/2007 8:01 am Reid Bryson, known as the father of scientific climatology, considers global warming a bunch of hooey. The UW-Madison professor emeritus, who stands against the scientific consensus on this issue, is referred to as a global warming skeptic. But he is not skeptical that global warming exists, he is just doubtful that humans are the cause of it. There is no question the earth has been warming. It is coming out of the "Little Ice Age," he said in an interview this week. "However, there is no credible evidence that it is due to mankind and carbon dioxide. We've been ...

(Christian Science Monitor) This article was written by Mark Clayton. New data show the populations of some of America's well-known birds in a tailspin, thanks to the one-two punch of habitat fragmentation and, increasingly, global warming. From the heartland's whippoorwills and meadowlarks to the Northern bobwhite and common terns of the nation's coasts, 20 common bird species tracked by the National Audubon Society have seen their numbers fall 54 percent overall since 1967, with some down about 80 percent, the group reported Thursday. Most of the trouble lies with loss of bird habitat, and has for decades, due to expanding agriculture and suburban development. The Rufous ...

HOUSTON (AP) - Russian cosmonauts on Saturday began turning back on some crucial systems that had been shut down more than four days ago when a computer system on the Russian side of the international space station crashed. The first system turned on was a machine that scrubs carbon dioxide from the air inside the space station. Just a day earlier, Fyodor Yurchikhin and Oleg Kotov were able to get four of six processors on two computers working again by using a cable to bypass a circuit board. It took four days to restore the capability of the computers. In addition, spacewalking astronauts on Friday were able to stitch up a peeled back thermal blanket near space shuttle Atlantis' ...

Rednecks Save the Space Program I recently received an email with the subject of “Redneck Time Out”. Attached was this photo. At first I thought it looked like an obvious case of child abuse. Then I saw that the baby was pretty relaxed. [The condition of the stuffed duck was questionable. He looked miserable. He probably had spinal cord damage as a result of being hung by the neck.] Little did I know that the parents of this child were possibly NASA employees practicing standard agency procedural policy. Yep, today I learned the truth. Confused? That’s OK. Stick with me. The link was on tonight’s news: NASA’s in-flight emergency plans cover astronaut going ...

HOUSTON -- Russian and U.S. engineers are drawing up plans to work around the failure of critical computers aboard the International Space Station (ISS) in time for the departure of the shuttle Atlantis next week. NASA's ISS program manager Mike Suffredini said engineers are studying alternatives to help maintain control of the space station's orientation, including using rockets aboard docked Russian spacecraft, once Atlantis' STS-117 crew casts off from the orbital laboratory on June 19. "The highest priority would be maintaining attitude once the shuttle has departed," Suffredini said Friday. The space station's six Russian computers governing control and ...

Testing nonlocal observation as a source of intuitive knowledge
Post Date: 2007-06-15 01:31:05 by Horse

This study explored the hypothesis that in some cases intuitive knowledge arises from perceptions that are not mediated through the ordinary senses. The possibility of detecting such “nonlocal observation” was investigated in a pilot test based on the effects of observation on a quantum system. Participants were asked to imagine that they could intuitively perceive a low intensity laser beam in a distant Michelson interferometer. If such observation were possible, it would theoretically perturb the photons’ quantum wave-functions and change the pattern of light produced by the interferometer. The optical apparatus was located inside a light-tight, double steel-walled ...
