Lifeline For Renewable Power

From Technology Review:

Without a radically expanded and smarter electrical grid, wind and solar will remain niche power sources.

Push through a bulletproof revolving door in a nondescript building in a dreary patch of the former East Berlin and you enter the control center for Vattenfall Europe Transmission, the company that controls northeastern Germany's electrical grid. A monitor displaying a diagram of that grid takes up most of one wall. A series of smaller screens show the real-time output of regional wind turbines and the output that had been predicted the previous day. Germany is the world's largest user of wind energy, with enough turbines to produce 22,250 megawatts of electricity. That's roughly the equivalent of the output from 22 coal plants--enough to meet about 6 percent of Germany's needs. And because Vattenfall's service area produces 41 percent of German wind energy, the control room is a critical proving ground for the grid's ability to handle renewable power.

Why Isn't The Darkest Month Of The Year Also The Coldest?

From Slate:

Sunday marked the winter solstice—both the official start of winter and the shortest day of the year. But December is rarely as cold as January. Why isn't the month with the least sunlight also the one with the lowest temperatures?

Because water retains heat. Between 70 percent and 75 percent of the Earth's surface is covered in oceans, rivers, and lakes. (There's even more water vaporized in the air or stored in the ground.) During seasons of longer days and more sunlight, these geographical features are able to store up and retain heat over long periods of time, before emitting it as the days get shorter. A body of water is far more effective as a space heater than, say, a big field of rocks: The water holds on to five times as much heat per gram.

From Science Daily:

ScienceDaily (Dec. 27, 2008) — Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face, according to a report published online on December 18th in Current Biology, a Cell Press publication. The study—the first to examine brain activity in chimpanzees after they attempt to match fellow chimps' faces—offers new insight into the origin of face recognition in humans, the researchers said.

"We can learn about human origins by studying our closest relatives," said Lisa Parr, a researcher at the Yerkes National Primate Research Center, Emory University. "We can discover what aspects of human cognition are really unique and which are present in other animals."

2009 To Arrive Not A Second Too Soon

From Yahoo News/Space:

Wait a second. The start of next year will be delayed by circumstances beyond everyone's control. Time will stand still for one second on New Year's Eve, as we ring in the New Year on that Wednesday night. As a result, you'll have an extra second to celebrate because a "Leap Second" will be added to 2008 to let a lagging Earth catch up to super-accurate clocks.

By international agreement, the world's timekeepers, in order to keep their official atomic clocks in step with the world's irregular but gradually slowing rotation, have decreed that a Leap Second be inserted between 2008 and 2009.

The extra second, ordered by the world's nominal timekeeper, the International Earth Rotation and Reference Systems Service, will be marked officially at the stroke of midnight on Wednesday in Greenwich, England, the home of what is popularly known as Greenwich Mean Time (GMT) – Coordinated Universal Time (UTC) to the more technically inclined – the standard time for the planet.

Half Of The USA Is Covered In Snow

From Watts Up With That?:

This is something you don’t see every day. We recently heard that Canada had a white Christmas EVERYWHERE, the first time in four decades. Here we see that the USA has an increased albedo (surface reflectivity) for about 1/2 of it’s land area. The increased albedo combined with low sun angle this time of year conspires to keep ice and snow unmelted.

Look for a long and extended winter weather pattern as we head towards the spring equinox, which can’t get here fast enough.

Here is a more colorful view of snow depth on Dec 25th from the National Hydrologic Remote Sensing Center:

Scientific Illiteracy All The Rage Among The Glitterati

From The Independent:

When it comes to science, Barack Obama is no better than many of us. Today he joins the list of shame of those in public life who made scientifically unsupportable statements in 2008.

Closer to home, Nigella Lawson and Delia Smith faltered on the science of food, while Kate Moss, Oprah Winfrey and Demi Moore all get roastings for scientific illiteracy.

The Celebrities and Science Review 2008, prepared by the group Sense About Science, identifies some of the worst examples of scientific illiteracy among those who profess to know better – including top politicians.

Mr Obama and John McCain blundered into the MMR vaccine row during their presidential campaigns. "We've seen just a skyrocketing autism rate," said President-elect Obama. "Some people are suspicious that it's connected to the vaccines. This person included. The science right now is inconclusive, but we have to research it," he said.

2008 Was The Year Man-Made Global Warming Was Disproved

Polar bears will be fine after all Photo: AP

From The Telegraph:

Looking back over my columns of the past 12 months, one of their major themes was neatly encapsulated by two recent items from The Daily Telegraph.

The first, on May 21, headed "Climate change threat to Alpine ski resorts" , reported that the entire Alpine "winter sports industry" could soon "grind to a halt for lack of snow". The second, on December 19, headed "The Alps have best snow conditions in a generation" , reported that this winter's Alpine snowfalls "look set to beat all records by New Year's Day".

Easily one of the most important stories of 2008 has been all the evidence suggesting that this may be looked back on as the year when there was a turning point in the great worldwide panic over man-made global warming. Just when politicians in Europe and America have been adopting the most costly and damaging measures politicians have ever proposed, to combat this supposed menace, the tide has turned in three significant respects.

Dino Extinction May Have Been Caused By ‘Magnetic Chaos’

From Zeenews.com:

Washington, Dec 13: A new theory has suggested that the mass extinction event that killed the dinosaurs 250 million years ago, was caused by the Earth’s magnetic field going into complete disarray, exposing the planet to a shower of cosmic radiation.

According to a report in Discovery News, the theory has been put forward by Yukio Isozaki of the University of Tokyo.

The Permian-Triassic mass extinction event happened 250 million years ago, snuffing out 90 percent of life on the planet.

Now, the new theory by Isozaki suggests that the catastrophe was set in motion 15 million years earlier, deep in the Earth.

From Live Science:

When you see something of value, your brain essentially sees dollar signs, a new study finds.

The effect occurs even if you don't consciously realize the object's worth.

Researchers scanned the brains of subjects who were presented with choices of constantly changing red and green objects that represented 10 cents or nothing, with good choices in a game leading to potential winnings of $10.

Upon seeing objects that had been of value previously, brain activity lit up in several areas, including a part of the cortex known as V1, which is associated with representing basic features such as edge orientations and color.

From Voice Of America:

At NASA, 2008 will be remembered for shuttle missions, discoveries on Mars, and mysteries revealed across the solar system and beyond. While looking back at the U.S. space agency's 2008 successes, VOA looks at the agency's uncertain future and its plans to bring humankind to Moon.

NASA's Constellation project is accelerating, with engineers building and testing rockets and capsules that will be the primary vehicles for human space exploration after the shuttle fleet is retired in 2010.

The core of NASA's current activities is a return to the moon, with astronauts landing there by 2020.

Regenerate Your Brain? -The Science Says It's Possible

From Daily Galaxy:

Contrary to popular belief, recent studies have found that there are probably ways to regenerate brain matter.

Animal studies conducted at the National Institute on Aging Gerontology Research Center and the Johns Hopkins University School of Medicine, for example, have shown that both calorie restriction and intermittent fasting along with vitamin and mineral intake, increase resistance to disease, extend lifespan, and stimulate production of neurons from stem cells.

In addition, fasting has been shown to enhance synaptic elasticity, possibly increasing the ability for successful re-wiring following brain injury. These benefits appear to result from a cellular stress response, similar in concept to the greater muscular regeneration that results from the stress of regular exercise.

The Shape Of Things To Come On The Internet

Internet Sites Could Be Given 'Cinema-Style Age Ratings', Culture Secretary Says -- The Telegraph

Internet sites could be given cinema-style age ratings as part of a Government crackdown on offensive and harmful online activity to be launched in the New Year, the Culture Secretary says.

In an interview with The Daily Telegraph, Andy Burnham says he believes that new standards of decency need to be applied to the web. He is planning to negotiate with Barack Obama’s incoming American administration to draw up new international rules for English language websites.

The Cabinet minister describes the internet as “quite a dangerous place” and says he wants internet-service providers (ISPs) to offer parents “child-safe” web services.

Winter Cold Puts A Chill On Green Energy

In Minnesota, Alan Stankevitz did a new winter chore for homeowners: clearing the solar panels. Alan Stankevitz

From The New York Times:

Old Man Winter, it turns out, is no friend of renewable energy.

This time of year, wind turbine blades ice up, biodiesel congeals in tanks and solar panels produce less power because there is not as much sun. And perhaps most irritating to the people who own them, the panels become covered with snow, rendering them useless even in bright winter sunshine.

So in regions where homeowners have long rolled their eyes at shoveling driveways, add another cold-weather chore: cleaning off the solar panels. “At least I can get to them with a long pole and a squeegee,” said Alan Stankevitz, a homeowner in southeast Minnesota.

Space Station Cargo Delivery Still Expensive

From Future Pundit:

Orbital Sciences Corp has won a $1.9 billion contract to carry 20 metric tons of cargo to the International Space Station in 8 flights. Think about those numbers. That's $95 million per metric ton to move cargo from ground level to low orbit. Those deliveries start in 2011 and run through 2015. A metric ton is 1000 kilograms or 2204.6 lbs. So the cost of putting stuff into low Earth orbit in 2015 is still going to be around $43k per lb or $95k per kg. At these prices large scale human colonization of space still seems a very distant prospect.

Those costs will come down a lot if a beanstalk into space built using nanotubes becomes possible. A bigger cost reduction for a Mars mission will come from nanotech advances. A bunch of nanodevices that can transform Mars landscape and produce needed supplies for a colony would reduce the size of the payload needed for setting up an initial colony.

Google's Grand Ambitions

From CBS:

(CNET) Google stretched its wings in 2008, furthering an expansion beyond its core search and search-advertising business. But the economy and the government raised the possibility that those wings could be clipped.

The company began the year overcoming opposition to its $3.1 billion acquisition of DoubleClick, a move that gave Google more clout in the market for graphical "display" ads. But that antitrust fight was a harbinger of things to come.

In April, Google showed its ambitions to house not just its own online applications such as Google Docs, but also others' with a project called Google App Engine. Basic applications are free, but more taxing ones cost money, a pay-as-you-go model that's popular with the cloud-computing concept.

Tiny Clues To Collision In Space

From BBC:

Evidence that a massive meteorite shower had an impact on Earth on a global scale 470 million years ago have been found on a Highlands beach.

Researchers from the University of Aberdeen uncovered tiny remnants of meteorites, smaller than a grain of sand, within rocks in Sutherland.

The find is linked to others made in China, the US and Australia.

The scientists think the meteorites - a result of a collision in space - triggered earthquakes and tsunami.

The university said the find near Durness confirmed previous scientific speculation that the meteorite shower - which followed a "catastrophic event" in an asteroid belt between Mars and Jupiter - was so vast in size that it affected locations across the globe.

The World's Most High-Tech Nation

From ABC News:

If there ever is an "Easy Tech Adaptation for Dummies" book, I’d be the first one to grab it. Living in the most wired country in the world is quite a struggle for people with technology phobia like me. I’m not talking new gadgets or software that are released every few months or years. I’m talking almost every day learning how to use new functions on my mobile phone or keeping up to date with new ways to communicate.

Today, I joined the tech-savvy generation’s new thing: T-mobile money, only to find myself all frustrated because the whole concept is too good to be true and way too complex. It is a prepaid smart card that is embedded into your mobile’s SIM card, which works as a wallet, navigator or personalized weather forecaster. It even tells you how crowded -- not with car traffic but with human traffic -- certain places are so that you can avoid holiday shopping at those spots!

From Science Daily:

ScienceDaily (Dec. 25, 2008) — In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate.

Normally, foraging honey bees alert their comrades to potential food sources only when they've found high quality nectar or pollen, and only when the hive is in need. They do this by performing a dance, called a "round" or "waggle" dance, on a specialized "dance floor" in the hive. The dance gives specific instructions that help the other bees find the food.

Foraging honey bees on cocaine are more likely to dance, regardless of the quality of the food they've found or the status of the hive, the authors of the study report.

Discovery Indicates Mars Was Habitable

From Live Science:

Evidence of a key mineral on Mars has been found at several locations on the planet's surface, suggesting that any microbial life that might have been there back when the planet was wetter could have lived comfortably.

The findings offer up intriguing new sites for future missions to probe, researchers said.

Observations NASA's Mars Reconnaissance Orbiter (MRO), which just completed its primary mission and started a second two-year shift, found evidence of carbonates, which don't survive in conditions hostile to life, indicating that not all of the planet's ancient watery environments were as harsh as previously thought.

The findings are detailed in a study in the Dec. 19 issue of the journal Science and will be presented today at the annual meeting of the American Geophysical Union in San Francisco

Quantum Computer Could Solve Problems In A Few Months That Would Take Conventional Computers Millions Of Years

From Science Daily:

ScienceDaily (Sep. 13, 2001) — How to build a super fast computer that uses the bizarre properties of quantum physics is the aim of a project by computer scientists Fred Chong of the University of California, Davis, Isaac Chuang at MIT and John Kubiatowicz at UC Berkeley. The five-year project is supported by a grant of $3 million from the Defense Advanced Research Projects Agency. The grant will establish a Quantum Architecture Research Center between MIT, UC Davis and UC Berkeley.

A quantum computer could solve problems in a few months that would take conventional computers millions of years, Chong said.

Quantum physics describes the special rules that apply to atoms and subatomic particles. One principle is that when you observe a particle, you change it. If a particle can be in one of two states, for example "up" or "down," it only settles on one state when you look at it. Before you look at it, it can be in both states at the same time.
