A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars.
The High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took two images of Phobos 10 minutes apart on March 23. Scientists combined the images for a stereo view.
"Phobos is of great interest because it may be rich in water ice and carbon-rich materials," said Alfred McEwen, HiRISE principal investigator at the Lunar and Planetary Laboratory at the University of Arizona, Tucson.

U.S. audio historians have discovered and played back a French inventor's historic 1860 recording of a folk song -- the oldest-known audio recording -- made 17 years before Thomas Edison invented the phonograph.
"It's magic," audio historian David Giovannoni said on Thursday. "It's like a ghost singing to you."
Lasting 10 seconds, the recording is of a person singing "Au clair de la lune, Pierrot repondit" ("By the light of the moon, Pierrot replied") -- part of a French song, according to First Sounds, a group of audio historians, recording engineers, sound archivists and others dedicated to preserving humankind's earliest sound recordings.

An international team of astronomers has discovered the coldest brown dwarf star ever observed. This finding, to be published in Astronomy & Astrophysics, is a new step toward filling the gap between stars and planets.
An international team  led by French and Canadian astronomers has just discovered the coldest brown dwarf ever observed. Their results will soon be published in Astronomy & Astrophysics
. This new finding was made possible by the performance of telescopes worldwide : Canada France Hawaii Telescope (CFHT) and Gemini North Telescope, both located in Hawaii, and the ESO/NTT located in Chile.

Spanish and UCL (University College London) scientists have discovered a possible terrestrial-type planet orbiting a star in the constellation of Leo. The new planet, which lies at a distance of 30 light years from the Earth, has a mass five times that of our planet but is the smallest found to date. One full day on the new planet would be equivalent to three weeks on Earth.

The brightest light on Earth now shines in a laboratory in Texas, one which will enable scientists to create a tabletop star. The $14m Texas Petawatt laser reached greater than one petawatt - one thousand million million watts - of laser power in the past few days, making it the highest powered laser in the world, says Prof Todd Ditmire, a physicist at The University of Texas at Austin.
Every year, the American Institute of Aeronautics and Astronautics awards prizes for the best papers presented at its annual conference. Last year's winner in the nuclear and future flight category went to a paper calling for experimental tests of an astonishing new type of engine. According to the paper, this hyperdrive motor would propel a craft through another dimension at enormous speeds. It could leave Earth at lunchtime and get to the moon in time for dinner. There's just one catch: the idea relies on an obscure and largely unrecognised kind of physics. Can they possibly be serious?

Sure, they can
, but are they? In their paper "Future space propulsion based on Heim's field theory"
W. Dröscher and J. Häuser write:
Again, as was said in , the authors are aware of several shortcomings in this paper. Not all of the physical features of Heim's theory were de-rived properly. Some of the conclusions are based on a somewhat speculative physical model concerning the generation of gravitophoton particles.
It should be mentioned that Heim's legacy is very large, several thousand pages, and his presentation style is not the one of contemporary physics. Heim uses his own terminology that needs to be translated into the language of modern physics. In addition, since his theory is completely geometric, there are many concepts that have no counterpart in modern physics. Whether his theory is actually true, can only be determined by experiment.
And then, further:
Heim's theory currently is not mainstream physics, but it contains several highly interesting ideas, and its geometric origin of the physical world, is appealing, at least to the authors. As far as the authors understand Heim's theory (many of his calculations remained unchecked so far, simply because of the amount and the difficulty of his work), [...]
In other words: the Authors do not understand Heim's theory, but they hope that someone will ;-)
Jack Sarfatti quotes Nobel Prize winner, physicist G. t'Hooft:
Berkant, Heim's work is incoherently presented in the AIAA paper. It
reads like gibberish. One wonders about the mind processes of the
AIAA engineers who selected it for an award. Again I remind you of
Nobel Prize physicist's remark about it:

So what? What is the context. Einstein was wrong about locality in quantum theory. However, if it were not for Einstein raising the issue, most of modern quantum information theory would not exist - most likely. His EPR paper of 1935 was crucial even though he took a
position that proved false. No matter. Even Einstein's mistakes were great ones that were very important for the progress of physics. Great minds make mistakes that are more important than the Victorian Station Master's normal science discoveries. I suppose I am a Nietzschean? ;-)
And then he continues, writing to Ark:
Well if you think Heim's theory is correct, then explain it to all of us. Hauser's paper is unreadable. Ball is in your court.
Indeed it looks like a ball game ...;-)
The U.S. bio-fuels incentives put not just the U.S. food supply, but the global food supply, in competition with the fuel supply. Farmers (and corporate agriculture) in the U.S. took much of the corn crop to the refinery rather than to the food processing plants. Most of the food price increases seen in the U.S up until about a month ago were due solely to this shift.
Comment: The governments of the world, at least those run by psychopaths as the U.S. is, will do nothing to ward of the possibility of 3 billion people rioting for food. This situation is not an unfortunate result of their thoughtless actions. This situation is the intentional result of their well thought out plan.
That might be a difficult pill to swallow, but it is an undeniable fact. Things have gone wrong and seemed insane for far too long. The big question is, how much longer will you keep your eyes closed to the truth? You are being lead to the slaughter by psychopaths that have no regard for your life at all. Let's hope that it doesn't take personal involvement in a fight to the death over a loaf of bread for you to see it.
In the desert of north Phoenix, a man who lives in the area claims he has found an archaeological site that touches antiquity.
"To me, this was like finding a pyramid," Pete Norris says of the geoglyph he stumbled across several months ago.
He believes the glyph, made up of a circle of stones, some precisely placed larger rocks, a pile of quartz pieces and a separate line of stones, could even be older than the Egyptian pyramids.

LONDON - Archaeologists conducting a major excavation at England's Stonehenge said they had made a key breakthrough that may help explain why the site was built, the BBC said Wednesday.
According to the broadcaster, which is funding the dig as part of a special programme to be broadcast in the autumn, the team of archaeologists has reached a series of sockets that once held bluestones, smaller stones, most of which are now missing, that made up Stonehenge's original structure.
The bluestones were transported from hills in Wales, some 250 kilometres (155 miles) away, and the researchers think they were brought to the iconic site on Salisbury Plain in Wiltshire, west England, because ancient people believed they had healing properties.
