Elephants need only three to four hours of sleep per night in order to be their happy elephant selves during the day. So what's Dumbo's secret? Deeper, more stable sleep--and new research may have found the secret to helping you achieve elephantine-levels of repose each night: Pink noise...Pink noise is a type of sound in which every octave carries the same power, or a perfectly consistent frequency, Zhang explains. "Think of rain falling on pavement, or wind rustling the leaves on a tree," It's called pink noise because light with a similar power spectrum would appear pink, he says.
Additionally, on a somewhat separate note, the production of melatonin, a natural chemical used to put your body to sleep at night, is diminished in the presence of bright blues (and likely to be the reason why your laptops are keep you up at night). Software such f.lux dimish the blues on screen to allow for better sleep. (note: I am in no way, shape or form, associated with f.lux. I just like their product and am not aware of any other software that does the same.)" Link to Original Source top
mayberry42 (1604077) writes "Astronomers using the Hubble Space Telescope are mystified by a merging galaxy cluster known as Abell 520 in which concentrations of visible matter and dark matter have apparently come unglued. A report on the Hubble observations, published in the Astrophysical Journal, raises more questions than answers about a cosmic pile-up that's occurring 2.4 billion light-years away.
"According to our current theory," says Arif Babul, the study team's senior theorist, "galaxies and dark matter are expected to stay together, even through a collision. But that's not what's happening in Abell 520. Here, the dark matter appears to have pooled to form the dark core, but most of the associated galaxies seem to have moved on.""

Boston University Economics Professor Seeks to Run
mayberry42 (1604077) writes "BU Economics Professor Lawrence Kotlikoff seeks to run for presidency in the 2012 presidential race. Being late in the game and with the additional handicap of running as an independent, it is unlikely that he will make any significant impact." Link to Original Source top

And the results are, to say the least, universally astounding. Famitsu magazine has given it a perfect score, and IGN stating "The Legend of Zelda: Skyward Sword is the greatest Zelda game ever created. It's the best game for Wii and one of the finest video game accomplishments of the past 10 years." Of course, some of you may have already known this given that it has already been hacked (and yes, it looks even more fantastic in HD). I would love to hear what our European counterparts have to say about this game. Have you played it? Is it as good as they say? Why or why not?" top

However, things have turned to almost bizarre levels when the past few debates have almost entirely excluded him, at one point granting him 90 seconds to speak — in an 80 minute debate. Still, he seems to be doing pretty well in Iowa." top

CNET was just as positive, giving a rating of "very good". Engadget, while not as enthusiastic, did say it was "quite an achievement for $200". Given the recent study that the kindle could pose a threat to Apple, this could be interesting to watch. Now for the Nook..." top

Khan Academy Receives $5M to Expand, Create Physic
Khan Academy announced this morning that it has raised $5 million from the O’Sullivan Foundation (a foundation created by Irish engineer and investor Sean O’Sullivan). The money is earmarked for several initiatives: expanding the Khan Academy faculty, creating a content management system so that others can use the program’s learning analytics system, and building an actual brick-and-mortar school, beginning with a summer camp program.
mayberry42 (1604077) writes "Did you ever wonder how and why professional economists often seem to get it wrong in terms of predicting consequences or policies accurately (or even at all)? Or how very few even saw the current economic collapse? This article provides an interesting, if obvious, reason as to why economic models are effectively always wrong. Of course, the recent press conference with the two recent nobel prize winners does not bode well to our most beloved social science either." Link to Original Source top
WASHINGTON — Fulfilling a long-held campaign promise, President Barack Obama announced Friday that he will pull all U.S. troops out of Iraq by the end of the year, as conditioned by the Status of Forces Agreement with the country.
"As a candidate for president, I pledged to bring the war in Iraq to a responsible end," Obama said. "So today I can report that, as promised, the rest of our troops in Iraq will come home by the end of the year."
Scientists have found Earth's oldest fossils in Australia and say their microscopic discovery is convincing evidence that cells and bacteria were able to thrive in an oxygen-free world more than 3.4 billion years ago.
The finding suggests early life was sulphur-based — living off and metabolizing sulphur rather than oxygen for energy — and supports the idea that similar life forms could exist on other planets where oxygen levels are low or non-existent.
While the (news) title may have been a bit sensationalistic, it's still exciting to know that life could exist in a very different environment that what we previously believed." Link to Original Source

mayberry42 (1604077) writes "While the United States (arguably) managed to survive the catastrophe with a credit downgrade of the "Big Three" — and possible default on debt — it has not been so lucky abroad.

The important question now is, how much impact will this have, especially since China is U.S.'s largest bond holder." Link to Original Source top

BBC News - Runway opens at world's first spaceport
Commercial space travel took a step closer with the opening of the runway at the world's first spaceport in the US state of New Mexico. The event was marked with a flypast of an aircraft carrying SpaceShip Two. The vehicle has been designed to take fee-paying tourists on trips to the edge of space and back. British billionaire Sir Richard Branson — whose Virgin group has backed the venture — said the first passenger trip should take place within 18 months.
