Denver 'UFO' Likely Has Earthly Explanation
An unusual video of mysterious dark objects moving very quickly and erratically over the skies of Denver, Colo., has local residents buzzing.
Fox affiliate KDVR reporter Heidi Hemmat described "an unusual object that appears to launch and land in the metro area." The Federal Aviation Administration (FAA) had no record of anything unusual in the skies at the time, either visually or on radar. |  |
Pitlochry UFO was 'Forestry Commission vehicle light'
Investigators studying footage of a possible UFO seen above a Perthshire forest have come up with a more terrestrial explanation.
The strange light was recorded above Clunie Forest near Pitlochry by Adrian Musat on 5 November. He sent the footage to the British UFO Research Association (BUFORA) for analysis. |  |
United States returns to Peru last Machu Picchu artefacts
The last of the artefacts taken from Machu Picchu by American archaeologist who rediscovered the Inca citadel have been returned to Peru.
More than 35,000 pottery fragments and other pieces were flown from Yale University to the Andean city of Cusco. They had been taken to the US by archaeologist Hiram Bingham, who brought the site to international attention in 1911. |  |

US to become world leader in oil and gas thanks to fracking
The United States will leapfrog Saudi Arabia and Russia to become the world's biggest producer of oil and gas in the next five years as the controversial practice of "fracking" for hydrocarbons contained in shale rocks has enabled the country to increase production massively, according to an authoritative new report.
In a development that will reshape the geopolitical map, US oil and gas production is set to leap by about a quarter by 2020 as the rapid growth of hydraulic fracturing, or fracking, propels the country towards providing all its own energy by 2035, according to this year's keenly watched World Energy Outlook report from the International Energy Agency.

Quasars Help Shed Light on Dark Energy Mystery
There's exciting news today for those following the quest to comprehend dark energy -- the mysterious repulsive force that fills the universe, causing its expansion to accelerate. New results from the Baryon Oscillation Spectroscopic Survey (BOSS) -- part of the Sloan Digital Sky Survey (SDSS-III) -- relying on data from quasars have enabled physicists to produce a detailed 3D "map" of the early universe a whopping 11.5 billion years ago.

Almost being there: Why the future of space exploration is not what you think
Mocup is a tiny, adorable remote-controlled robot built from a Lego Mindstorms set with an off-the-shelf Beagleboard computer for a brain and a webcam for an eye. The machine is not fundamentally different from many other RC robots — except for the fact that its controller operates it from space.
The cat-sized robot can do little more than move around, avoid obstacles, and transmit video. It’s mostly a testbed for communications to help humans in orbit and robots on the surface of a planet work seamlessly together. |  |
Iceman Mummy Finds His Closest Relatives
SAN FRANCISCO — Ötzi the Iceman, an astonishingly well-preserved Neolithic mummy found in the Italian Alps in 1991, was a native of Central Europe, not a first-generation émigré from Sardinia, new research shows. And genetically, he looked a lot like other Stone Age farmers throughout Europe.
The new findings, reported Thursday (Nov. 8) here at the American Society of Human Genetics conference, support the theory that farmers, and not just the technology of farming, spread during prehistoric times from the Middle East all the way to Finland. |  |
French mammoth may have been Neanderthal lunch
CHANGIS-SUR-MARNE, France (Reuters) - French archaeologists have uncovered a rare, near-complete skeleton of a mammoth in the countryside near Paris, alongside tiny fragments of flint tools suggesting the carcass may have been cut into by prehistoric hunters.
The archaeologists say that if that hypothesis is confirmed, their find would be the clearest ever evidence of interaction between mammoths and ancient cavemen in this part of Europe.
"Evidence this clear has never been found before, at least in France," said Gregory Bayle, chief archaeologist at the site.

'Super-Earth' Alien Planet May Be Habitable for Life
Astronomers have detected an alien planet that may be capable of supporting life as we know it — and it's just a stone's throw from Earth in the cosmic scheme of things.
The newfound exoplanet, a so-called "super-Earth" called HD 40307g, is located inside its host star's habitable zone, a just-right range of distances where liquid water may exist on a world's surface. And the planet lies a mere 42 light-years away from Earth, meaning that future telescopes might be able to image it directly, researchers said. |  |
World's Most Powerful Laser Facility Shifts Focus to Warheads
After an unsuccessful campaign to demonstrate the principles of a futuristic fusion power plant, the world’s most powerful laser facility is set to change course and emphasize its nuclear weapons research.
For the past six years, scientists and engineers at the US National Ignition Facility (NIF) have been working flat out to focus 192 laser beams on a gold-lined ‘hohlraum’ capsule, just a few millimeters long, containing a pellet of hydrogen isotopes. As 500 terawatts of laser power hits the capsule, it generates X-rays that blast into the pellet, causing the atoms of deuterium and tritium inside to fuse. The fusion converts a tiny amount of their mass into a burst of energy. |  |
Hydrogen fuel edges a step closer
Making hydrogen gas in water just got a little easier. The discovery may lead to inexpensive, practical means of harvesting sunlight to create clean-burning hydrogen for powering cars or generating electricity.
Scientists would like to mimic plant photosynthesis, which harvests sunlight and splits water molecules to create fuel. It sounds simple, but even in plants the task is a highly orchestrated set of reactions, with multiple players acting in multiple places. So researchers often tackle one half of photosynthesis at a time.

Interstellar dust and the sun
The space between stars is not empty. It contains copious but diffuse amounts of gas and dust; in fact about 5-10% of the total mass of our Milky Way galaxy is in interstellar gas. About 1% of the mass of this interstellar material, quite a lot in astronomical terms, is in the form of tiny dust grains made predominantly of silicates (sand too is made of silicates), though some grains are also composed of carbon and other elements. Dust grains are important.

Flexible and transparent supercapacitor: for energy-storage devices...
Cell phones as thin and flexible as a sheet of paper. Energy-storing house paint. Roll-up touch screen displays. These are the sorts of devices that the engineering industry is preparing for and expecting. But if any of them is to work, said Northeastern University mechanical and industrial engineering professor Yung Joon Jung, experts also need to create a thin and flexible energy-storage system. His lab has developed such a system.

Ancient Temple Sheds Light on Early Power Struggles at Tel Beth-Shemesh
Tel Aviv University researchers have uncovered a unique 11th-century BCE sacred compound at the site of Tel Beth-Shemesh, an ancient village that resisted the aggressive expansion of neighboring Philistines. The newly discovered sacred complex is comprised of an elevated, massive circular stone structure and an intricately constructed building characterized by a row of three flat, large round stones. Co-directors of the dig Prof. Shlomo Bunimovitz and Dr. Zvi Lederman of TAU's Sonia and Marco Nadler Institute of Archaeology say that this temple complex is unparalleled, possibly connected to an early Israelite cult — and provides remarkable new evidence of the deliberate desecration of a sacred site.

Mongolia & Altai Mtns: Origins of genetic blending between Europeans & Asians
A group of researchers led by the Universitat Autònoma de Barcelona (UAB) has discovered the first scientific evidence of genetic blending between Europeans and Asians in the remains of ancient Scythian warriors living over 2,000 years ago in the Altai region of Mongolia. Contrary to what was believed until now, the results published in PLoS ONE indicate that this blending was not due to an eastward migration of Europeans, but to a demographic expansion of local Central Asian populations, thanks to the technological improvements the Scythian culture brought with them.

Wadi El-Hitan, the realm of the Lizard King
Wadi El-Hitan, Egypt’s only natural heritage site on the UNESCO World Heritage List, resembles a lunar landscape dotted with fossils of species over 40 million years old
“Wadi El-Hitan is the most important site in the world to demonstrate one of the iconic changes that make up the record of life on Earth: the evolution of the whales. It portrays vividly their form and mode of life during their transition from land animals to a marine existence” – The World Heritage Committee.

India unveils new version of ‘world’s cheapest tablet’
India has launched a new version of its ultra-low-cost tablet computer with a quicker processor and an improved battery, on sale to students at the subsidised price of $20.
The Aakash tablet, dubbed the world’s cheapest computer, has been developed as a public-private partnership aimed at making computing technology available to students in a country where Internet usage is only at around 10 percent. |  |
Enigma coding machine beats auction estimate in London
A rare Enigma encoding machine has sold at auction in London for £85,250.
That is more than its £40,000-£60,000 estimate, but less than the £131,180 price an Enigma sold for last year. The typewriter-like devices were used by the Nazis in World War II to encrypt and decode messages sent between the military and their commanders. |  |
Geronimo’s Appeal to Theodore Roosevelt
When he was born he had such a sleepy disposition his parents named him Goyahkla—He Who Yawns. He lived the life of an Apache tribesman in relative quiet for three decades, until he led a trading expedition from the Mogollon Mountains south into Mexico in 1858. He left the Apache camp to do some business in Casa Grandes and returned to find that Mexican soldiers had slaughtered the women and children who had been left behind, including his wife, mother and three small children. “I stood until all had passed, hardly knowing what I would do,” he would recall. “I had no weapon, nor did I hardly wish to fight, neither did I contemplate recovering the bodies of my loved ones, for that was forbidden. I did not pray, nor did I resolve to do anything in particular, for I had no purpose left.”.

The Wright Brothers' Famous 1903 Flying Machine Patent Is Missing
THE ATLANTIC
In March of 1903, the Wright brothers applied for a patent, swearing that "they verily believe themselves to be the original, first, and joint inventors of improvements in flying machines." It was granted three years later. But now it's nowhere to be found, according to a recent 60 Minutes report.
