Deep-sea temperatures rose 1,300 years before atmospheric CO2, ruling out the greenhouse gas as driver of meltdown, says study in Science.

WASHINGTON - Astronomers who stumbled upon a powerful burst of radio waves said on Thursday they had never seen anything like it before, and it could offer a new way to search for colliding stars or dying black holes.
They were searching for pulsars -- a type of rotating compacted neutron star that sends out rhythmic pulses of radiation -- when they spotted the giant radio signal.

Microsoft on Thursday began phasing in a slick new version of its Live Search service in a bid to gain ground on leading Internet search rivals Google and Yahoo.
Microsoft's improved Live Search will be available throughout the United States in a week and globally by the end of October, according to vice president of search and advertising platform group Satya Nadella.

Magnetic Snakes Create Water Current

Physicists at Argonne National Laboratory have found that magnetic particles suspended in water and subjected to an alternating magnetic field will form snake-shaped structures that can control the flow of the surrounding fluid. Current incarnations of the magnetic snake are a few centimeters long, but the team envisions much smaller versions as pumps to manipulate liquids on microscopic scales or precursors for next-generation magnetic recording media in future computers. The team's recent experiment shows that the speed of the water flowing along the snake depends on how quickly the magnetic field alternates.

|Alternating magnetic fields create snake-like chains of magnetic particles suspended in fluid. The snakes direct the flow of the surrounding fluid along their lengths, potentially leading to new methods to control fluids in chip-based chemical analysis.
When Georgia Tech Assistant Professor Kim Cobb and graduate student Jud Partin wanted to understand the mechanisms that drove the abrupt climate change events that occurred thousands of years ago, they didn't drill for ice cores from the glaciers of Greenland or the icy plains of Antarctica, as is customary for paleoclimatolgists. Instead, they went underground.
Growing inside the caves of the tropical Pacific island of Borneo are some of the keys to understanding how the Earth's climate suddenly changed - several times - over the last 25,000 years. By analyzing stalagmites, the pilar-like rock formations that stem from the ground in caves, they were able to produce a high-resolution and continuous record of the climate over this equatorial rainforest.
Cairo - Egyptian antiquities supremo Zahi Hawass insisted Tuesday that Tutankhamun was not black despite calls by US black activists to recognize the boy king's dark skin color.
"Tutankhamun was not black, and the portrayal of ancient Egyptian civilization as black has no element of truth to it," Hawass told reporters.
"Egyptians are not Arabs and are not Africans despite the fact that Egypt is in Africa," he said, quoted by the official MENA news agency.
Hawass said he was responding to several demonstrations in Philadelphia after a lecture he gave there on September 6 where he defended his theory.

NASA is about to embark on an unprecedented asteroid-belt mission with a spacecraft aptly named Dawn. The 3 billion-mile, eight-year journey to probe the earliest stages of the solar system will begin with liftoff, planned for just after sunrise Thursday. Rain is forecast, however, and could force a delay.
Scientists have been waiting for Dawn to rise since July, when the mission was put off because of the more pressing need to launch NASA's latest Mars lander, the Phoenix. Once Phoenix rocketed away in August, that cleared the way for Dawn.
The Solar and Heliospheric Observatory (SOHO) has spotted an unusual comet that flies around the sun at regular intervals.
Dubbed P/2007 R5 (SOHO)
, the object belongs to a rare class of comets
called periodic comets. Only 190 of the thousands of known comets are periodic. The most famous periodic comet is Halley's Comet, which can be seen from Earth every 76 years and last passed close to the sun in 1986.
Eight fruit-filled baskets and 20 sealed jars previously un-noticed by Egyptologists have been found concealed in a chamber adjoining the tomb of King Tutankhamun, a top Egyptian archaeologist said.
The 3,300-year-old find is highly surprising considering the vast number of visitors and researchers that have descended into the boy-pharaoh's tomb since British explorer Howard Carter discovered and broke into the treasure-packed burial place in the early 1920s.
Dr. Zahi Hawass, a world-famous Egyptologist who heads Egypt's Supreme Council of Antiquities, said his team of archaeologists had discovered baskets containing "large quantities of well-preserved doum [palm] fruits," and twenty pear-shaped vases bearing Tutankhamun's official seal.
Indeed, it is highly surprising discovery. Why now? What kind of game Zahi Hawass ('a world-famous Egyptologist
') is playing, and who's pulling his strings?
The entire structure of Egyptology rests on a fiction: the Bible. Egyptologists like Dr. Zahi Hawass have a role of maintaining this fiction, and we find it hard to believe that we would hear about such 'surprising discoveries' unless they had a purpose. So we must ask again: what is going on and why now? Who is sending a message and to whom?

Laura Knight Jadczyk said:
"So the question, of course, is since we see a certain condition prevailing in the World today where there is outrageous injustice and violence, and nobody is really putting their finger on the real issue and it's like Norman Finkelstein wrote in his book "Beyond Chutzpah", that at this point in time nobody disagrees with the facts of where, when and how Israel was formed, that there were 700 or 800 thousand Palestinians living in the Country, it was not empty, it was not void of population, and Great Britain had promised the Arabic population their own government in the Sikes-Picot agreement and then they turned around and made the Balfour declaration and this was, what?, 1917?
And essentially gave the land that they had already promised the Arabs to have their own government and gave it to someone else, out from under them. I mean, just think the enormous unfairness of this. This was so outrageous an act that it's hardly comprehensible. And getting into the why and wherefores, about that, of course at the time there was plenty of media manipulation and there was even an interesting event that took place right at that time that included Howard Carter who was the discoverer of the tomb of Tutankhamun and apparently there were several scrolls, manuscripts discovered in the tomb, and this was widely reported in the media for about a period of two weeks, and then it disappeared and all of a sudden it was covered up and it was said "Oh no, they mistook some rolls of linen" and it wasn't until several months later that apparently Howard Carter, in a... and this was after, of course, after Lord Carnarvon had died, mysteriously, I should add, that Howard Carter threatened the British officials with revealing the contents of the scrolls which were the true story of the Exodus, which is apparently found written on scrolls and papyrus in the tomb of Tutankhamun. And this was covered up, hushed up, by the British government."
Adventurer Steve Fossett went missing Sept. 3 about 70 miles southeast of Reno, Nevada, in a small plane. He left no flight plan, and searchers have combed tens of thousands of square miles of Nevada and California. After weeks of fruitless searches, and with the survival window closing, Web users were enlisted to help in Fossett's rescue, from the comfort of their own homes.
