Bridging the gap: A graphic released by Australian paleontologist Adam Yates shows the newly discovered dinosaur species - with the fossil bones found by the team marked on the outline
From The Daily Mail:
A new dinosaur named the 'Earth Claw' has been discovered in South Africa.
The discovery of the Aardonyx celestae marks a breakthrough in understanding how creatures began walking on all fours - and why they grew so large, scientists claimed yesterday.
Researchers believe the near-perfect skeleton bridges the gap between the earliest two-legged specimens and those who later walked on four limbs.

From CNET News:
Medpedia, a collaborative project for medical information launched in February, is getting beyond the medical-data basics as it adds answers, alerts, and analysis.
Founded on the noble and semipractical system of providing free online medical information generated for and by physicians, journals, schools, patients, and more, Medpedia's three stated goals are to be collaborative, interdisciplinary, and transparent. The idea is to maximize knowledge and minimize the kind of screwing around that continually threatens the efficacy of other wiki-based projects. Of course, the extent to which this is successful hinges on the quality, integrity, and transparency of the editors.
Seeking. You can't stop doing it. Sometimes it feels as if the basic drives for food, sex, and sleep have been overridden by a new need for endless nuggets of electronic information. We are so insatiably curious that we gather data even if it gets us in trouble. Google searches are becoming a cause of mistrials as jurors, after hearing testimony, ignore judges' instructions and go look up facts for themselves. We search for information we don't even care about. Nina Shen Rastogi confessed in Double X, "My boyfriend has threatened to break up with me if I keep whipping out my iPhone to look up random facts about celebrities when we're out to dinner." We reach the point that we wonder about our sanity. Virginia Heffernan in the New York Times said she became so obsessed with Twitter posts about the Henry Louis Gates Jr. arrest that she spent days "refreshing my search like a drugged monkey."
We always knew that the National Security Agency collects a lot of surveillance data from satellites and by other means, but we never quite imagined it was this much: the NSA estimates it will have enough data by 2015 to fill a million datacenters spread across the equivalent combined area of Delaware and Rhode Island. The NSA wants to store yottabytes of data, and one yottabyte comes to 1,000,000,000,000,000 GB.

Today, Friday the 13th superstitions are fraying nerves for the third time in 2009.
Luckily for paraskevidekatriaphobics—people who harbor Friday the 13th superstitions—three Friday the 13ths are the yearly maximum, at least as long as we continue to mark time with the Gregorian calendar, which Pope Gregory XIII ordered the Catholic Church to adopt in 1582.
Lunar Impactor Finds Clear Evidence Of Water Ice On Moon -- Wired Science
There is water on the moon, NASA confirmed today, and lots of it.
In the first look at results from the LCROSS mission, which sent a probe crashing into the Cabeus crater near the moon’s south pole, NASA’s main investigator said their instruments clearly detected water, despite the underwhelming plume.
Within the field of view of their instruments, the team measured approximately 220 pounds or about 26 gallons of water. Next, the team will try to understand how the compounds they saw in the plume relate to what’s actually embedded in the lunar regolith at the bottom of the permanently shadowed crater.
This spectacular image of our home planet was captured by Europe's Rosetta probe as it made its third and final flyby of Earth.
The outline of Antarctica is visible under the clouds in the illuminated crescent. Pack ice in front of the coastline caused the very bright spots on the image.
The Earth image was taken by the-board camera OSIRIS yesterday, from a distance of 393,000 miles.

From Science News:
Scorpionflies may have aided plant reproduction long before blossoms evolved.
An obscure group of scorpionflies with specialized mouthparts may have pollinated ancient plants millions of years before flowers evolved, a new study suggests.
Fossils indicate that before flowers evolved about 130 million years ago, most plants with seeds were wind-pollinated. Yet the pollen grains of some plants that lived in the prefloral era were too big to be wind-dispersed, say Conrad Labandeira, a paleoentomologist at Smithsonian Institution’s National Museum of Natural History in Washington, D.C. Also, he notes, pollen receptors were hidden deep within some of those plants and wouldn’t have been readily exposed to windborne pollen.

From Science Daily:
Science Daily (Nov. 13, 2009) — When Europe's comet chaser Rosetta swings by Earth on Nov. 13 for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.
Since 1990, scientists and mission controllers at ESA and NASA have noticed that their spacecraft sometimes experience a strange variation in the amount of orbital energy they exchange with Earth during planetary swingbys. The unexplained variation is noticed as a tiny difference in speed gained or lost during the swingby when comparing that predicted by fundamental physics and that actually measured after the event.
If Friday the 13th is unlucky, then 2009 has been an unusually unlucky year. But your luck is about to change. Today is the last of three Friday the 13ths you'll have to endure this year.
The other two were in February and March. Such a rare triple-threat occurs only once every 11 years.
The origin of the link between bad luck and Friday the 13th is murky. The whole thing might date to Biblical times (the 13th guest at the Last Supper betrayed Jesus). By the Middle Ages, both Friday and the number 13 were considered bearers of bad fortune. In modern times, the superstition permeates society.
Human speech is thought to have emerged 100,000 to 200,000 years ago, some five million years after chimps and humans took divergent paths on the tree of evolution. Photo: iStockphoto
From Cosmos:
PARIS: Two minute evolutionary changes in a gene that is otherwise identical in humans and chimps could explain why we have fully fledged power of speech while other primates do not.
The findings may also point to new drug targets for hard-to-treat diseases that disrupt speech, such as schizophrenia and autism, said a study detailed in the British journal Nature today.
The Centers for Disease Control and Prevention (CDC) released on Thursday updated estimates of the number of H1N1 infections and deaths in the U.S. According to the new figures, about 4,000 Americans, including 540 children, have died of H1N1 flu, and 2 million people have been infected since April, when the novel flu virus first surfaced. The new death toll, which encompasses data through Oct. 17, represents a tripling of CDC estimates issued just last week; the number of deaths in children quadruples last week's figures. But the increase does not mean that the disease has suddenly become more deadly or severe, according to health officials, who say they are not surprised by the higher numbers.

From New Scientist:
NASA's twin Mars rovers have outlasted their planned three-month missions for so long that they seem indestructible. Nearly six years on, their presence on the Red Planet is taken for granted, as if they are immutable parts of the Martian landscape.
But we may soon have to confront a new reality. Spirit, which has always suffered more hardships than Opportunity, is facing its toughest challenge yet. When New Scientist went to press, the rover was set to begin a risky push to free itself from a sand trap it has been mired in for six months. Mission engineers say it may not survive the attempt. "She's in a very precarious situation, and we don't know for sure if we're going to get her out," says rover driver Scott Maxwell of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.

ABOARD THE ALGUITA, 1,000 miles northeast of Hawaii — In this remote patch of the Pacific Ocean, hundreds of miles from any national boundary, the detritus of human life is collecting in a swirling current so large that it defies precise measurement.
In 1804, a little over 200 years ago, the planet had a human population of 1 billion people. Back then the oceans seemed immense and beyond the capacity of humans to change. Yet by 1850 whale hunting peaked due to over harvesting and we've since drastically drawn down the stocks of other ocean-going creatures such as cod and salmon.

The USS New York, commissioned this month in its namesake city, is the Navy's newest warship. It's a Landing Platform Dock ship, which means it brings Marines to wherever they are needed. The 700 marines on the ship travel ready for combat, and that means landing hovercraft (called Landing Craft Air Cushions), attack helicopters, tanks, amphibious vehicles and V-22 Ospreys come along for the ride. The aircraft launch from the ship and are maintained in hangars on and below the flight deck. The New York has the most famous hull in the world—the Navy integrated 7.5 tons of steel from the fallen World Trade Center towers into the bow. But that is not the only interesting detail of this new vessel's design. Here are four high-tech surprises the USS New York has in store for enemies.
AS DAMP squibs go, it was quite a spectacular one. Amid great pomp and ceremony - not to mention dark offstage rumblings that the end of the world was nigh - the Large Hadron Collider (LHC), the world's mightiest particle smasher, fired up in September last year. Nine days later a short circuit and a catastrophic leak of liquid helium ignominiously shut the machine down.
Now for take two. Any day now, if all goes to plan, proton beams will start racing all the way round the ring deep beneath CERN, the LHC's home on the outskirts of Geneva, Switzerland.

Psychic Spies: Any Truth in 'Men Who Stare at Goats?' -- ABC News
Movie, Book Claim Military Officers Dabbled in the Paranormal
Major Paul H. Smith calls it his "Men in Black" moment.
It was 1983 and he was working as a Middle East analyst at Fort Meade, Md., when a fellow intelligence officer approached him with a highly-classified, so-called "black project."
They couldn't tell him what it was. They just said that as an intelligent, accomplished, open-minded and creative person, he fit the profile.
Intrigued, Smith agreed to take the tests thrown at him. And when the results confirmed his competence for the top-secret task, he was invited to try his hand at a new mission: To uncover details about places and activities around the world without stepping off of a U.S. military base.
"We're basically asking you to become a psychic spy," Smith, now retired, said he was told.

From Science Daily:
Science Daily (Nov. 11, 2009) — A group of engineers working on a novel manufacturing technique at NASA's Langley Research Center in Hampton, Va., have come up with a new twist on the popular old saying about dreaming and doing: "If you can slice it, we can build it."
That's because layers mean everything to the environmentally-friendly construction process called Electron Beam Freeform Fabrication, or EBF3, and its operation sounds like something straight out of science fiction.
Scientists have zeroed in on one apparent key to long life: an inherited cellular repair mechanism that thwarts aging and perhaps helps prevent disease. Researches say the finding could lead to anti-aging drugs.
The study involves telomeres, the ends of chromosomes that have been likened to the plastic tips that prevent shoelaces from unraveling. Telomeres were already known to play a key role in aging, and their discovery led to this year's Nobel Prize in medicine.

From National Geographic:
At Veterans Day celebrations and events around the country, the United States is honoring the men and women of the nation's armed forces.
So why is November 11 Veterans Day? Who is it for? And how has it changed?
In keeping with Veterans Day tradition, U.S. President Barack Obama today laid a wreath at the Tomb of the Unknowns at Arlington National Cemetery in Virginia, saying, "While it is important and proper that we mark this day, it is far more important we spend all our days determined to keep the promises that we've made to all who answer this country's call."
LARGE two-legged dinosaurs, such as Tyrannosaurus rex, were energetic athletes with warm blood running through their veins, it was claimed today. New evidence suggests that the ancient reptiles were endothermic – or warm-blooded – like their modern descendants, birds.
Far from being lumbering slow beasts, they were likely to have been agile and active.
But warm blood would have come at a price, because it requires more food. If food became scarce 65 million years ago, this could have been a contributory factor in their extinction.
