U.S., China, India and Other Nations Arrive at Non-Binding Agreement At U.N. Climate Summit
From Scientific American:
A new draft agreement from both developed and developing countries might prove the key to combating climate change.
COPENHAGEN—The U.S., China, India and South Africa form the core of a growing group of nations that have agreed upon a commitment to combat climate change, concluding a grueling two weeks of negotiations in the Danish capital here as part of the United Nations' climate summit. The so-called "Copenhagen Accord" will not be legally binding but will list in annexed documents, for the first time, commitments from both developed and developing countries to reduce emissions of greenhouse gases.

Head Games: How Helmet Tech Works In 7 Different Sports
From Popular Mechanics:
It's deep into football season, and players benched because of concussions have begun to seem as common as a turnover. That's because, after a string of damning studies, the relationship between head impacts and brain trauma, leading to cognitive impairment later in life, has become difficult to ignore. Football's not the only sport that puts players' heads at risk, though. From Nascar to skiing and cycling, here's what's considered state-of-the-art headgear.

Ardi - Cousin Of The 'Missing Link' - Named Scientific Breakthrough Of 2009
From The Telegraph:
The discovery of a short, ape like creature, that lived more than four million years ago just as humans began walking on two legs was the most important breakthrough of the year, according to one of the most prestigious science magazines.
Ardi - a seven stone, four-foot tall female who roamed African forests 4.4million years ago- was the oldest member of the human family tree found so far, pre-dating the previous ancestor "Lucy" by a million years.
Her discovery, reported in October, sheds light on a crucial period when we were just leaving the trees.

Majority of U.S. Cocaine Supply Cut with Veterinary Deworming Drug
From Popular Science:
Cocaine's a hell of a drug, and even more so when laced with another drug that's commonly used to deworm opossums. Federal agents have found that 69 percent of cocaine shipments seized entering the United States contain levamisole, a veterinary drug linked to serious weakening of the immune system in humans. Here's the real funny part: no one knows why.

The US Air Force's Holiday Wish List: 2500 PlayStations
From The New Scientist:
The US Air Force Research Lab recently put out a request for 2200 Sony PlayStation 3 games consoles. The military researchers want to wired them up with the 300 or so they already have to make a type of supercomputer never seen before.
But it won't be the ultimate gaming system to teach pilots how to blast enemies out of the sky. Instead it will analyse radar and simulate the workings of brains.
The consoles are desirable because of the unique abilities of the chip at their heart. Jointly designed by Sony, Toshiba and IBM, the Cell chip is designed for the speedy and efficient graphics processing that gaming requires, as well as for number crunching.

Mammals May Be Nearly Half Way Toward Mass Extinction
From Science Daily:
Science Daily (Dec. 18, 2009) — If the planet is headed for another mass extinction like the previous five, each of which wiped out more than 75 percent of all species on the planet, then North American mammals are one-fifth to one-half the way there, according to a University of California, Berkeley, and Pennsylvania State University analysis.
Many scientists warn that the perfect storm of global warming and environmental degradation -- both the result of human activity is leading to a sixth mass extinction equal to the "Big Five" that have occurred over the past 450 million years, the last of which killed off the dinosaurs 68 million years ago.

Fake Platelets To Stem Blood Flow
From Cosmos:
SYDNEY: Scientists have developed artificial platelets to enhance the natural process of blood clotting, reducing the risk of fatal blood loss on the battlefield and in the emergency room.
Platelets are colourless disc-shaped cells which activate the blood clotting process, helping to form 'plugs' which stop blood flowing from cuts and grazes. However, they are sometimes overpowered by serious injury or trauma, which can lead to fatal blood loss.

The Big Question: Has A Key Breakthrough Been Made In The Search For A Cure For Cancer?
From The Independent:
Why are we asking this now?
British scientists announced yesterday that they have sequenced a "cancer genome" for the first time. It means they have identified all of the many thousands of genetic mistakes that make a tumour cell different from a healthy cell taken from the same cancer patient.
Not all of these mistakes, or DNA mutations, were involved in triggering the cancer, but some of them – the "drivers" – clearly were. Scientists believe it will be possible eventually to identify these driver mutations and find the genetic faults that led to the changes in a healthy human cell that caused it to divide uncontrollably to form a cancerous tumour.

Davy Jones's Lock-Up
From The Economist:
Underwater robots can help study the world’s shipwrecks, a trove of information about the past, more easily and cheaply.
A SHIPWRECK is a catastrophe for those involved, but for historians and archaeologists of future generations it is an opportunity. Wrecks offer glimpses not only of the nautical technology of the past but also of its economy, trade, culture and, sometimes, its warfare. Until recently, though, most of the 3m ships estimated to be lying on the seabed have been out of reach. Underwater archaeology has mainly been the preserve of scuba divers. That has limited the endeavour to waters less than 50 metres deep, excluding 98% of the sea floor from inspection. Even allowing for the tendency of trading vessels to be coasters rather than ocean-going ships, that limits the number of wrecks available for discovery and examination.

Texting Now More Popular Than Cell Calls
From CBS News:
(AP) R u kidding me? Americans punched out more than 110 billion text messages last year, double the number in the previous year and growing, as the shorthand communication becomes a popular alternative to cell phone calls.
The nation's 270 million cell phone subscribers each sent out an average of 407 text messages in 2008, according to government statistics released Tuesday by the Census Bureau. That's more than double the 188 messages sent by the average cell subscriber in 2007. The figures did not break down the texting by age, but the overall numbers understate the thousands of texts sent each month by many teens - balanced out by older folks who don't text as much.

Close-Up Photos Of Dying Star Show Our Sun's Fate
From Science Daily:
Science Daily (Dec. 17, 2009) — About 550 light-years from Earth, a star like our Sun is writhing in its death throes. Chi Cygni has swollen in size to become a red giant star so large that it would swallow every planet out to Mars in our solar system. Moreover, it has begun to pulse dramatically in and out, beating like a giant heart. New close-up photos of the surface of this distant star show its throbbing motions in unprecedented detail.
"This work opens a window onto the fate of our Sun five billion years from now, when it will near the end of its life," said lead author Sylvestre Lacour of the Observatoire de Paris.

The Science Behind James Cameron's Avatar
From Popular Mechanics:
It's the year 2154 and humankind has reached out to the stars in director James Cameron's new science-fiction epic Avatar. The movie takes us to an exotic jungle moon called Pandora where humans are the aliens and a clash is brewing with the natives. Cameron, who has served as an adviser to NASA to investigate a camera for a Mars mission, is known for taking the science in his flicks very seriously. So how did he do? Here we check on some of the movie's scientific bona fides with top researchers in their respective fields to see where artistic license and scientific plausibility meld.

The Amalgamated Flying Saucer Club Of America, Headquartered In Los Angeles, Released This Photo, Taken By A Member, Reportedly Showing A Flying Sauce
From Time Magazine:
The year 1969 was a great time for hippies, a bad year for Beatles fans and an even worse year for UFO enthusiasts. Forty years ago, on Dec. 17th, the U.S. Air Force officially shuttered Project Blue Book, the agency's third and final attempt to investigate extraterrestrial sightings and the country's longest official inquiry into UFOs. From 1952 until 1969, more than 12,000 reports were compiled and either classified as "identified" — explained by astronomical, atmospheric or artificial phenomenon — or "unidentified," which made up just 6% of the accounts. Because of such a meager percentage and an overall drop in sightings, officials axed the program and ended the research. So much for the truth being out there.

Moon Poses Radiation Risk To Future Travelers
From Discovery News:
Rather than blocking cosmic rays, the moon itself is a powerful source of radiation, measurements show.
Future lunar explorers counting on the moon to shield themselves from galactic cosmic rays might want to think about Plan B.
In a surprising discovery, scientists have found that the moon itself is a source of potentially deadly radiation.
Measurements taken by NASA's Lunar Reconnaissance Orbiter show that the number of high energy particles streaming in from space did not tail off closer to the moon's surface, as would be expected with the body of the moon blocking half the sky.

Military Could Use iPhones To Track Friends, Enemies in War
From The Gadget Lab:
What if the iPhone could be used in war? True, it’s primarily a consumer product, but it’s versatile and always connected to the internet (assuming you have network reception) — so why not?
That’s the idea behind new iPhone apps being showcased by Raytheon, a military contractor, at the Intelligence Warfighting Summit in Tucson. One app called the One Force Tracker will provide live data tracking the location of friends and foes on real-time maps. The app will also be used to communicate with other units.

More Homes Seen Dumping Landlines
From CBS News:
Age And Location Biggest Factor In Decisions To Abandon Landlines.
(AP) The number of households with cell phones but no landlines continues to grow, but the recession doesn't seem to be forcing poor cellular users to abandon their traditional wired phones any faster than are higher-income people.
The finding, from data compiled by the federal Centers for Disease Control and Prevention, suggests that when it comes to telephone habits, peoples' decisions are affected more by age and where they live than by their economic situations.

Climate Change Is Nature's Way -- A Commentary
Climate Change Is Nature's Way.
Climate change activists are right. We are in for walloping shifts in the planet's climate. Catastrophic shifts. But the activists are wrong about the reason. Very wrong. And the prescription for a solution—a $27 trillion solution—is likely to be even more wrong. Why?
Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.

Will 2010 Be The Breakout Year For E-Book Readers?
From Stltoday:
When Sheila Effan found a Kindle electronic reader among her gifts last Christmas, one of her first thoughts was whether she'd miss the smell and feel of real paper. She got her answer five months later.
That's when a friend lent her a paperback. She lugged it around for a couple of days before tiring of the burden.
"I got annoyed with it. So I just downloaded it to my Kindle," Effan said. "I thought I would miss books. But I don't."
Oh, how the folks behind Amazon.com's Kindle, Sony's Reader and Barnes & Noble's Nook love the sound of that.

Climate Change Does Not Always Lead to Conflict
Science Daily (Dec. 17, 2009) — The climate change that took place in Mesopotamia around 2000 BC did not lead to war, but in fact led to the development of a new shared identity. Although increasing drought often leads to competition and conflict, there seems to be no evidence of this in northern Mesopotamia according to Dutch researcher Arne Wossink.
Wossink studied how the farmers and nomads in northern Mesopotamia -- currently the border area between Turkey, Syria and Iraq -- responded to the changes in climate that took place between 3000 and 1600 BC. He expected to find considerable evidence of competition: as food and water became scarcer the natural result could well be conflict. He discovered, however, that the farmers developed much closer bonds with the semi-nomadic cattle farmers.

Most Earth-Like Extrasolar Planet Found Right Next Door
From Wired Science:
Meet GJ 1214b, the most Earth-like planet ever found outside our solar system.
It’s not exactly Earth’s twin: It’s about six times bigger, a whole lot hotter and made mostly of water. But compared to the giant gas balls that account for nearly every other extrasolar planet ever found, it’s pretty darn close. And through a fortunate happenstance of cosmic geometry, astronomers will be able to study GJ 1214b in great detail.
“If you want to describe in one sentence what this planet is, it’s a big, hot ocean,” said Harvard University astronomer David Charbonneau. “We can even study its atmosphere. This planet will occupy us for years. That’s part of what’s so exciting about it.”

New Displays For E-Readers: Read All About It
From The Economist:
Display technology: Readers of electronic books must choose between long battery life or vibrant, living colour. Could they have both?
THE sudden surge in the popularity of e-readers—slate-like devices, such as Amazon’s Kindle, on which electronic books can be read—has been one of the big surprises of 2009. Recessions are often a good time to launch new products, as old certainties are questioned and consumer tastes shift. The iPod made its debut in 2001 in the depths of America’s recession, and e-readers may prove to be a similar success story this time. But today’s e-readers, like that first iPod, are technologically quite simple. Most of them have a monochromatic screen to display text and black-and-white pictures, and none can handle video.
Even so, around 5m e-readers will be sold worldwide in 2009, according to iSuppli, a market-research firm, and a further 12m in 2010. The Kindle is by far the most popular e-reader, but there are many others.

The Publishing Disruption
What a unique thing a book is. Made from a tree, it has a hundred or more flexible pages that contain written text, enabling the book to contain a large sum of information in a very small volume. Before paper, clay tablets, sheepskin parchment, and papyrus were all used to store information with far less efficiency. Paper itself was once so rare and valuable that the Emperor of China had guards stationed around his paper possessions.
Before the invention of the printing press, books were written by hand, and few outside of monasteries knew how to read. There were only a few thousand books in all of Europe in the 14th century. Charlemagne himself took great effort to learn how to read, but never managed to learn how to write, which still put him ahead of most kings of the time, who were generally illiterate.

15% Of Teens 'Sexting' On Cells, Study Says
From San Francisco Chronicle:
About 15 percent of American teenagers have received nude or sexually suggestive photos on their cell phones, and that percentage doubles as teens get older, according to a study released Tuesday about the tech-fueled trend called "sexting."
Boys are as likely as girls to send sexts, while teens who pay for their own cell phone bills are more likely to text salacious shots, according to the study by the Pew Internet and American Life Project of Washington.
The study does show the vast majority of teens aren't sexting, with 4 percent of 12- to 17-year-olds admitting to sexting photos or videos of themselves.

Who Needs The Grid?
In the boardroom at Bloom Energy, a single picture hangs on the wall: a satellite image of the world at night. Clusters of bright lights mark the industrial centers, and thin white lines trace connecting passageways such as the U.S. Interstate System and the Trans-Siberian Railroad. In between, huge swaths lie in shadow.
Standing almost reverently before the image, K. R. Sridhar, the CEO of Bloom, points to the dark areas—places where electricity isn’t accessible or reliable. “This is my motivation for everything,” he says. To improve the lot of the more than 2 billion people living in those dark areas, he says, you have to get them reliable, affordable energy. And if you don’t want to doom the environment in the process, you have to make that energy very clean.

New Underwater Explorers Go Where Scientists Can't
From Popular Mechanics:
Last week, an unmanned robot completed a 3300-mile trek across the Atlantic Ocean for the first time. The 134-pound robot, a glider named the Scarlet Knight, spent months at sea, gathering data on ocean temperature and salinity between the water's surface down to 600 feet below. The Scarlet Knight is just one of many new technologies scientists are turning to in order to research oceans, rivers and lakes—areas that are impractical, and in some cases impossible, for researchers to access themselves. By employing everything from robots to, yes, tadpoles, scientists hope to learn more about how climate change and pollution are affecting the earth's water. Here is some of the newest tech aiding scientists.

The Beckoning Silence: Why Half Of The World's Languages Are in Serious Danger Of Dying Out
From The Independent:
Of the 6,500 languages spoken in the world, half are expected to die out by the end of this century. Now, one man is trying to keep those voices alive by reigniting local pride in heritage and identity.
High up, perched among the remote hilltops of eastern Nepal, sits a shaman, resting on his haunches in long grass. He is dressed simply, in a dark waistcoat and traditional kurta tunic with a Nepalese cap sitting snugly on his head. To his left and right, two men hold recording devices several feet from his face, listening patiently to his precious words. His tongue elicits sounds alien to all but a few people in the world, unfamiliar even to those who inhabit his country. His eyes flicker with all the intensity of a man reciting for the first time to a western audience his tribe's version of the Book of Genesis, its myth of origins.
