Wiser Wires -- Smart grids
From The Economist:
Information technology can make electricity grids less wasteful and much greener. Businesses have lots of ideas and governments are keen, but obstacles remain
WHAT was the greatest engineering achievement of the 20th century? The motor car, perhaps, or the computer? In 2000 America’s National Academy of Engineering gave a different answer: “the vast networks of electrification”. These, the academy concluded, made most of the century’s other advances possible.

Youth 'Cannot Live' Without Web
From The BBC:
A survey of 16 to 24 year olds has found that 75% of them feel they "couldn't live" without the internet.
The report, published by online charity YouthNet, also found that four out of five young people used the web to look for advice.
About one third added that they felt no need to talk to a person face to face about their problems because of the resources available online.
The findings were unveiled at the Houses of Parliament on Wednesday.

WIKIMEDIA COMMONS/FLCELLOGUY
From Scientific American:
Oil demand in industrialized countries peaked in 2005 and will not reach that high again, a new report predicts.
Demand for oil in developed nations peaked in 2005, and changing demographics and improved motor-vehicle efficiency guarantee that it won't hit those heights again, IHS Cambridge Energy Research Associates says in a new report.
Reduced petroleum demand in developed nations could make their economic growth less vulnerable to oil price shocks, the report states.

Natural Gas Changes the Energy Map
Deep drilling: At Range Resources’ site in Washington County, PA, a specially designed rig is used to drill more than a thousand meters down and gradually turn 90° to follow the gas-rich shale deposit. The rig will drill half a dozen wells at the site. Beside it is a pond holding debris and mud from a well. Credit: Roy Ritchie
From Technology Review:
Vast amounts of the clean-burning fossil fuel have been discovered in shale deposits, setting off a gas rush. But how it will affect our energy use is still uncertain.
The first sign that there's something unusual about the flat black rocks strewn across the shore of Lake Erie comes when Gary Lash smashes two of them together. They break easily and fall into shards that give off the faint odor of hydrocarbons, similar to the smell of kerosene. But for Lash, a geologist and professor at nearby SUNY Fredonia, smashing the rocks is a simple trick designed to catch the attention of a visitor. The black outcroppings that protrude from the nearby bluff onto the narrow beach are what really interest him.

The Supercollider And A Theory About Fate
From CNET:
More than a year after an explosion of sparks, soot, and frigid helium shut it down, the world's biggest and most expensive physics experiment, known as the Large Hadron Collider, is poised to start up again.
Before year's end, if all goes well, protons will start smashing together in an underground racetrack outside Geneva in a search for forces and particles that reigned during the first trillionth of a second of the Big Bang.

Time-Travelling Higgs Sabotages The LHC. No, Really
From New Scientist:
Could the Large Hadron Collider be sabotaging itself from the future? That's the suggestion of a couple of reasonably distinguished theoretical physicists, which has received a fresh airing in the New York Times today.
Actually, it's the Higgs boson that is doing the sabotage. Apparently, among the many singular properties of the Higgs that the LHC is meant to discover could be the ability to turn back time to stop its cover being blown.
Or as the New York Times puts it:
"the hypothesized Higgs boson... might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."

Whatever Happened To Global Warming? How Freezing Temperatures Are Starting To Shatter Climate Change Theory
Sun or sea? The importance of the ocean's cooling and warming cycles are now under serious consideration as a key factor in global temperatures
From The Daily Mail:
In the freezing foothills of Montana, a distinctly bitter blast of revolution hangs in the air.
And while the residents of the icy city of Missoula can stave off the -10C chill with thermals and fires, there may be no easy remedy for the wintry snap's repercussions.

Researchers Discover Mechanism That Helps Humans See In Bright And Low Light
From Science Daily:
Science Daily (Oct. 14, 2009) — Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly. The same process also allows the eye to function in bright light.

The Link Between Parkinson Disease And Farming
From Live Science:
Although genetics is very important in Parkinson disease (PD), many researchers believe that environmental exposures also increase a person's risk of developing the disease. There are studies that show that farmers and other agricultural workers have an increased risk of getting PD.
PD was first described in 1817 by Dr. James Parkinson, a British physician. It affects 1 in 100 people over the age of 60. It can also affect younger people. The average age of onset is 60. Research suggests that PD affects at least 500,000 people in the United States.

Gallery: Let the X-Planes Begin
From Autopia:
Few aircraft are as storied as the experimental series known as the X-Planes. These flying laboratories date to the mid-1940s and took us ever higher, further and faster.
The first, the Bell X-1, was developed to explore transonic flight after fighter pilots began experiencing control problems as they approached the speed of sound in dives. Since then, a long list of X-Planes — and other test aircraft lacking the official ‘X’ moniker — have explored the unknown edge of aerodynamics and aviation. From the early days of supersonic flight and speed records to the possibilities of unmanned combat aircraft, X-Planes have, as their pilots say, pushed the edge of the envelope.

Modern Man 'A Wimp', Says Anthropologist
From The Independent:
Many prehistoric Australian aboriginals could have outrun world 100 and 200 metres record holder Usain Bolt in modern conditions.
Some Tutsi men in Rwanda exceeded the current world high jump record of 2.45 meters during initiation ceremonies in which they had to jump at least their own height to progress to manhood.
Any Neanderthal woman could have beaten former bodybuilder and current California governor Arnold Schwarzenegger in an arm wrestle.

Marine Plant Life Holds The Secret To Preventing Global Warming
Mangrove forests, salt marshes and seagrass beds, above, cover less than 1 per cent of the world's seabed, but lock away well over half of all carbon to be buried in the ocean floor
From Times Online:
Life in the ocean has the potential to help to prevent global warming, according to a report published today.
Marine plant life sucks 2 billion tonnes of carbon dioxide from the atmosphere every year, but most of the plankton responsible never reaches the seabed to become a permanent carbon store.
Mangrove forests, salt marshes and seagrass beds are a different matter. Although together they cover less than 1 per cent of the world’s seabed, they lock away well over half of all carbon to be buried in the ocean floor. They are estimated to store 1,650 million tonnes of carbon dioxide every year — nearly half of global transport emissions — making them one of the most intense carbon sinks on Earth.

Gene Linked To Better And Faster Decision Making
From The Telegraph:
Decision-makers are born not made, say scientists, as they discover people inherit a decisive gene.
The researchers found that people with a particular gene made quicker and more accurate decisions.
They were also better at learning tasks that require rapid and flexible decision-making compared to those with a different genetic make-up.

Jupiter Moon’s Ocean Is Rich In Oxygen
The strange striations on Europa's surface are thought to have been caused by tidal stresses from Jupiter as the ice cracks and warmer layers come to the surface. The same process may be responsible for transporting oxygen below the surface. Credit: NASA
From Cosmos:
SYDNEY: The globe-spanning ocean on Jupiter’s moon Europa contains about twice the liquid water of all Earth’s oceans combined, says a new study, which finds it’s packed with oxygen which could support life.
Research completed by Richard Greenberg a planetary scientist at the University of Arizona in Tucson, USA, suggests that there could be as much as 100 times the amount of oxygen previously estimated. The findings were presented last week at a meeting of the American Astronomical Society in Fajardo, Puerto Rico.

Finger Points To New Da Vinci Art
From BBC:
A new Leonardo da Vinci portrait may have been discovered after a fingerprint found on it seemed similar to another discovered on his work.
A Paris laboratory found the fingerprint is "highly comparable" to one on a da Vinci work in the Vatican.
Antiques Trade Gazette reported that the work, previously catalogued as "German, early 19th Century", could be worth tens of millions of dollars.
The work previously changed hands for around $19,000 (£12,039).

Bizarre Galaxy Is Result Of Pair Of Spiral Galaxies Smashing Together
Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. NGC 2623 is in the late stages of the merging process, with the centres of the original galaxy pair now merged into one nucleus, but stretching out from the centre are two tidal tails of young stars, a strong indicator that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. (Credit: NASA, ESA and A. Evans (Stony Brook University, New York & National Radio Astronomy Observatory, Charlottesville, USA))
From Science Daily:
Science Daily (Oct. 14, 2009) — A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies that resemble our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab).

Flying Reptile May Have Snatched Dinosaurs In Midair
The newly discovered remains of the flying reptile, now called Darwinopterus modularis, suggest the animals may have been an aerial predator, hunting small feathered dinosaurs (such as the one depicted here) and tiny gliding mammals some 160 million years ago. Credit: Mark Witton, University of Portsmouth.
From Live Science:
A crow-sized reptile sporting a lengthy tail likely soared through the skies some 160 million years ago, snatching feathered dinosaurs and tiny flying mammals from the air, suggest fossils of a newly identified pterosaur.
While paleontologists can't go back in time to watch the in-flight meal capture, the reptile's fossils, discovered recently in China's Liaoning Province, left behind compelling clues, the researchers say this week in the journal Proceedings of the Royal Society B: Biological Sciences.
