All of life’s ingredients found in Orion nebula
The ingredients for life as we know it have been found in the Orion Nebula.
By finely separating the spectrum of incoming light, astronomers are able to detect the chemical fingerprints of molecules like water and methanol. The spectrograph that their work produces can be seen in the image above. The peaks represent the presence of the molecule indicated.
The new data was collected by the Herschel Telescope, launched into space last year by the European Space Agency. Herschel’s HiFi instrument uses a new technique to do more-sensitive spectroscopy. It will enable scientists to better understand the chemistry of space.
The Orion Nebula is located about 1,300 light-years away. No very active star-forming region is closer to Earth. M42, as the nebula is also known, is 24 light-years across.

The Biggest Crop Circle Ever: The Reality Show
“Almost 60 acres. 530 x 450 meters in size. Created in an evening of August, 2009, at the province of Zeeland, Netherlands, it’s the biggest “crop circle” ever created. And with a twist.
Everything was recorded in video, as this was definitely a very human creation. To be more exact, a creation of 60 humans captured in its process from concept to realization by the cameras of the reality TV show “Try Before You Die”.
The culprits are the members of XL D-Sign team, which has been creating fantastic formations for more than ten years – many of which are promoted as “mysterious” to this day. This latest one, the biggest one to date, was properly named project Atlas, and aimed not only to break the size record but also depict “a message of both the beauty and vulnerability of man”.
The gigantic formation can be interpreted in several ways, from the metamorphosis of a butterfly, to the Vitruvian Man, to Mothman and perhaps even chakras. All part of a human symbology, with a human message, created by humans to humans, surpassing in size every crop circle ever created.”

Da Vinci’s Huge Horse Statue Proven Feasible
“‘Il Cavallo,’ the huge equine statue Leonardo Da Vinci never got to make, wasn’t plagued by technical problems as was widely believed, a new multidisciplinary research has revealed.
On the contrary, Da Vinci’s plan for the largest equestrian statue in the world was a perfectly feasible project which, if completed, would have probably been his greatest legacy, more than ”The Last Supper” or any other work.
Commissioned in 1482 by Lodovico Sforza, duke of Milan, in honor of his father Francesco, the massive bronze horse took Leonardo 17 years of research, but was never completed.
Indeed, when the full-scale clay model was finally ready to be cast in a single operation in 1499, all the needed bronze was used to make cannons for an imminent war against the King of France.
The molds were lost and the clay model was reduced to rubble by the invading French soldiers.
Although Leonardo never stopped mourning the ‘horse-that-never-was,’ engineers have always believed the daring plan to make the largest single-pouring cast ever would have failed because of technical problems.”

Extreme Weirdness: Antarctica’s “Blood Falls”
“There is a glacier in Antarctica that seems to be weeping a river of blood. It’s one of the continent’s strangest features, and it’s located in one of the continent’s strangest places — the McMurdo Dry Valleys, a huge, ice-free zone and one of the world’s harshest deserts.
A bleeding glacier. Discovered in 1911 by a member of Robert Scott’s ill-fated expedition team, its rusty color was at first theorized to be caused by some sort of algae growth. Later, however, it was proven to be due to iron oxidation. Every so often, the glacier spews forth a clear, iron-rich liquid that quickly oxidizes and turns a deep shade of red. According to Discover Magazine –
The source of that water is an intensely salty lake trapped beneath 1,300 feet of ice, and a new study has now found that microbes have carved out a niche for themselves in that inhospitable environment, living on sulfur and iron compounds. The bacteria colony has been isolated there for about 1.5 million years, researchers say, ever since the glacier rolled over the lake and created a cold, dark, oxygen-poor ecosystem.
Even weirder: scientists think that the bacteria responsible for Blood Falls might be an Earth-bound approximation of the kind of alien life that might exist elsewhere in the solar system, like beneath the polar ice caps of Mars and Europa.”

Earth’s Magnetic Field Older Than Previously Thought
“Evidence for the existence of Earth’s magnetic field has been pushed back about 250 million years, new research suggests. The field may therefore be old enough to have shielded some of the planet’s earliest life from the sun’s most harmful cosmic radiation.
Earth’s magnetic field was born by 3.45 billion years ago, a team including researchers from the University of Rochester in New York and the University of KwaZulu-Natal in South Africa report in the March 5 issue of Science.
That date falls during life’s earliest stages of development, between the period when the Earth was pummeled by interplanetary debris and when the atmosphere filled with oxygen. Several earlier studies had suggested that a magnetic field is a necessary shield against deadly solar radiation that can strip away a planet’s atmosphere, evaporate water and snuff out life on its surface.”

Oldest Writing, And Oldest English Writing
“COULD these lines etched into 60,000-year-old ostrich eggshells be the earliest signs of humans using graphic art to communicate?
Until recently, the first consistent evidence of symbolic communication came from the geometric shapes that appear alongside rock art all over the world, which date to 40,000 years ago (New Scientist, 20 February, p 30). Older finds, like the 75,000-year-old engraved ochre chunks from the Blombos cave in South Africa, have mostly been one-offs and difficult to tell apart from meaningless doodles.
The engraved ostrich eggshells may change that. Since 1999, Pierre-Jean Texier of the University of Bordeaux, France, and his colleagues have uncovered 270 fragments of shell at the Diepkloof Rock Shelter in the Western Cape, South Africa.”

And (possibly) in English:
“What is believed to be the first ever example of English written in a British church has been discovered. Problem is, no-one can read it.
The 500-year-old inscription was found on a wall in Salisbury Cathedral, Wiltshire, hidden behind a monument dedicated to an aristocrat.
The faded black lettering was discovered in January but experts have now asked for help from the public in a bid to make sense of the inscription.
Conservators came across the writing when they were preparing to clean a 350-year-old monument to Henry Hyde, a local aristocrat who was ‘martyred’ in the English Civil War for his support of King Charles I.
The text on the cathedral’s south aisle wall had been whitewashed over with lime, which is why it is hard to read.

Mercedes-Benz Museum Contains World Record Artificial Tornado
“The Mercedes-Benz Museum in Stuttgart, Germany is now home to more than just automobiles. The museum has been recognized by the Guinness Book of Records for creating the “strongest artificially generated tornado in the world.” The 34.4 meter high (that is 37.2 yards to those metrically challenged) vortex was not designed as an attraction, but to channel smoke out of the building in the event of a fire. The architecture wonderment that is the museum did not make use of any fire doors in the design (surely they would get in the way of the architect’s vision). In order to meet regulations, the building engineers had to determine a way to keep smoke from spreading beyond the fire level, the tornado is the resulting solution. The twister takes around seven minutes to materialize and is generated by 144 jets and 28 tons of air. The low pressure area at the center of the tornado works to create a jet stream that draws smoke out of the building’s corridors and funnels it upwards and out an exhaust vent on the roof. Check the gallery for photos of a carbon dioxide infused tornado demonstration.”

Massive Chile Earthquake May Have Shortened Earth’s Day
“Earth’s days may have gotten a little bit shorter since the massive earthquake in Chile, but don’t feel bad if you haven’t noticed.
The difference would be only about one-millionth of a second.
Richard Gross, a scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and colleagues calculated that Saturday’s quake shortened the day by 1.26 microseconds. A microsecond is one-millionth of a second.
The length of a day is the time it takes for the planet to complete one rotation – 86,400 seconds or 24 hours.
An earthquake can make Earth rotate faster by nudging some of its mass closer to the planet’s axis, just as ice skaters can speed up their spins by pulling in their arms. Conversely, a quake can slow the rotation and lengthen the day if it redistributes mass away from that axis, Gross said Tuesday.”

Real-Life Flat Earthers Still Continue To Believe
“Daniel Shenton should be the most irrational man in the world. As the new president of the Flat Earth Society, you’d imagine he would also think that evolution is a scam and global warming a myth. He should argue that smoking does not cause cancer and HIV does not lead to Aids.
Yes, that Flat Earth Society, a group that has become a living metaphor for backward thinking and a refusal to face scientific facts. Yes, it is still going, and no, this isn’t an early April fool.
In fact, Shenton turns out to have resolutely mainstream views on most issues. The 33-year-old American, originally from Virginia but now living and working in London, is happy with the work of Charles Darwin. He thinks the evidence for man-made global warming is strong, and he dismisses suggestions that his own government was involved with the 9/11 terrorist attacks.”
