From Christian Science Monitor:

Germans engineer an organic alternative from a paper waste product.

Almost 40 years ago, American scientists took their first steps in a quest to break the world’s dependence on plastics.

But in those four decades, plastic products have become so cheap and durable that not even the forces of nature seem able to stop them. A soupy expanse of plastic waste – too tough for bacteria to break down – now covers an estimated 1 million square miles of the Pacific Ocean.

Sensing a hazard, researchers started hunting for a substitute for plastic’s main ingredient, petroleum. They wanted something renewable, biodegradable, and abundant enough to be inexpensive.

From Live Science:

The term pot-head takes on new meaning with a study that suggests adolescents and young adults who smoked a lot of marijuana are more likely than non-users to have disrupted brain development.

Using brain scans, researchers found abnormalities in areas of the brain that interconnect brain regions involved in memory, attention, decision-making, language and executive functioning skills.

The findings are of particular concern because adolescence is a crucial period for brain development and maturation, the researchers note.

"Studies of normal brain development reveal critical areas of the brain that develop during late adolescence, and our study shows that heavy cannabis use is associated with damage in those brain regions," said study leader Manzar Ashtari of the Children's Hospital of Philadelphia.

2 Big Satellites Collide 500 Miles Over Siberia -- Yahoo News/AP

CAPE CANAVERAL, Fla. – Two big communications satellites collided in the first-ever crash of two intact spacecraft in orbit, shooting out a pair of massive debris clouds and posing a slight risk to the international space station.

NASA said it will take weeks to determine the full magnitude of the crash, which occurred nearly 500 miles over Siberia on Tuesday.

"We knew this was going to happen eventually," said Mark Matney, an orbital debris scientist at Johnson Space Center in Houston.

NASA believes any risk to the space station and its three astronauts should be low. It orbits about 270 miles below the collision course. There also should be no danger to the space shuttle set to launch with seven astronauts on Feb. 22, officials said, but that will be re-evaluated in the coming days.

From Newsweek:

In the elusive search for the reliable energy source of the future, the prospect of clean coal is creating a lot of buzz. But while the concept—to scrub coal clean before burning, then capture and store harmful gases deep underground—may seem promising, a coalition of environment and climate groups argue in a new media campaign that the technology simply doesn't exist.

The Alliance for Climate Protection and several other prominent organizations—including the Sierra Club and National Resources Defense Council—launched a multipronged campaign to "debrand" the clean part of clean coal, pointing out that there's no conclusive evidence to confirm the entire process would work the way it's being marketed. In the campaign's TV ad, a technician sarcastically enters the door of a clean coal production plant, only to find there's nothing on the other side. "Take a good long look," he says, standing in a barren desert, "this is today's clean coal technology."

From International Herald Tribune:

Amanda Kitts lost her left arm in a car accident three years ago, but these days she plays American football with her 12-year-old son, and changes diapers and bear-hugs children at the three Kiddie Cottage day care centers she owns in Knoxville, Tennessee.

Kitts, 40, does this all with a new kind of artificial arm that moves more easily than other devices and that she can control by using only her thoughts.

"I'm able to move my hand, wrist and elbow all at the same time," she said. "You think, and then your muscles move."

Her turnaround is the result of a new procedure that is attracting increasing attention because it allows people to move prosthetic arms more automatically than ever before, simply by using rewired nerves and their brains.

Wind Turbines In Europe Do Nothing For Emissions-Reduction Goals

Under current EU law, German wind turbines aren't helping to reduce CO2 emissions. They simply allow Eastern European countries to pollute more. REUTERS

From Spiegel Online:

Despite Europe's boom in solar and wind energy, CO2 emissions haven't been reduced by even a single gram. Now, even the Green Party is taking a new look at the issue -- as shown in e-mails obtained by SPIEGEL ONLINE.

Germany's renewable energy companies are a tremendous success story. Roughly 15 percent of the country's electricity comes from solar, wind or biomass facilities, almost 250,000 jobs have been created and the net worth of the business is €35 billion per year.

But there's a catch: The climate hasn't in fact profited from these developments. As astonishing as it may sound, the new wind turbines and solar cells haven't prohibited the emission of even a single gram of CO2.

Teens Spend Average Of 87 Hours A Year Looking At Porn Online

Teenagers are spending more than eight hours a week browsing the internet for soft porn, plastic surgery and family planning websites

From The Daily Mail:

The average teenager spends one hour and 40 minutes a week browsing sites for pornography, according to new research.

That equates to 87 hours a year spent surfing for porn. A further hour and 35 minutes is spent looking at dieting and weight loss websites.

The study of 1,000 youngsters found the average teenager was online 31 hours each week looking at soft pornography, plastic surgery, dieting, family planning and emotional support.

Another hour and eight minutes is dedicated to exploring cosmetic surgery websites, to learn about breast surgery, bum lifts and collagen implants.

The research was conducted by CyberSentinel.co.uk, a computer software that enables parents to block websites and monitor use of the internet.

From Science Daily:

ScienceDaily (Feb. 10, 2009) — A new paper in PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me.

"It's likely that every tooth made throughout the evolution of vertebrates has used this core set of genes," said Gareth Fraser, postdoctoral fellow at Georgia Tech's School of Biology.

The first vertebrates to have teeth were a group of eel-like jawless fish known as the conodonts that had teeth not in their mouth, but lining the throat. This particular group is long since extinct, but some modern fish retain teeth in the throat (pharynx). Dr. Fraser and colleagues studied tooth formation in a group of fish known for their rapid rate of evolution, the cichlids of Africa's Lake Malawi. The cichlids have teeth both in their oral jaws, like humans, and deep in their throats on a pharyngeal jaw. A co-author of the paper, Darrin Hulsey, first identified a surprising positive correlation between the number of teeth in the oral jaw and in the throat in these fish.

Mythic Birthplace of Zeus Said Found

The Chariot of Zeus image is from the 1879
"Stories from the Greek Tragedians" by Alfred Church.

From Live Science:

The Greek god of thunder and lightning had Earthly beginnings, and scientists think they finally know where.

Ancient Greeks first worshipped the omnipotent Zeus at a remote altar on Mount Lykaion, a team of Greek and American archaeologists now think. During a recent dig at the site, the researchers found ceremonial goods commonly used in cult activity and dated at over three millennia old, making them the earliest known "appearance" of Zeus in Greece.

The discovery challenges the idea that Zeus worship began on the Greek island of Crete, which at least one classical historian names as the god's mythic birthplace. The latest finds on Mount Lykaion, in the mainland province of Arcadia, are as old as the idea of Zeus himself, said the project's senior research scientist David Romano, of the University of Pennsylvania.

"This new evidence strongly suggests that there were drinking (and perhaps feasting) parties taking place on the top of the mountain in the Late Helladic period, around 3,300 or 3,400 years ago," Romano said.

It is enchanting, spectacular and - at 3.5m in diameter - it will soon become the biggest telescope mirror in space, surpassing that of Hubble.

The great 18th Century astronomer William Herschel would have been astonished by the silver sensation that now bears his name.

The European Space Agency (Esa) is certainly very proud of its new observatory. It has been working on the venture for more than 20 years.

"The mirror is an enormous piece of hardware," enthused Thomas Passvogel, Esa's programme manager on the Herschel space observatory.

Newborn Brain Cells 'Time-Stamp' Memories

Image from Impact Lab

From E! Science News:

LA JOLLA, CA—"Remember when…?" is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. A computational model developed by scientists at the Salk Institute for Biological Studies now suggests that newborn brain cells—generated by the thousands each day—add a time-related code, which is unique to memories formed around the same time. "By labeling contemporary events as similar, new neurons allow us to recall events from a certain period," speculates Fred H. Gage, Ph.D., a professor in the Laboratory for Genetics, who led the study published in the Jan. 29, 2009, issue of the journal Neuron. Unlike the kind of time stamp found on digital photographs, however, the neuronal time code only provides relative time.

Ironically, Gage and his team had not set out to explain how the brain stores temporal information. Instead they were interested in why adult brains continually spawn new brain cells in the dentate gyrus, the entryway to the hippocampus. The hippocampus, a small seahorse-shaped area of the brain, distributes memory to appropriate storage sections in the brain after readying the information for efficient recall.

Motivating Minds -- Why People Procrastinate

From The Economist:

People procrastinate when asked to think in the abstract

TO SOME there is nothing so urgent that it cannot be postponed in favour of a cup of tea. Such procrastination is a mystery to psychologists, who wonder why people would sabotage themselves in this way. A team of researchers led by Sean McCrea of the University of Konstanz, in Germany, reckon they have found a piece of the puzzle. People act in a timely way when given concrete tasks but dawdle when they view them in abstract terms.

Dr McCrea and his colleagues conducted three separate studies. First they recruited 34 students who were offered €2.50 ($3.30) for completing a questionnaire within the subsequent three weeks. Half of the students were then sent an email asking them to write a couple of sentences on how they might go about various activities, such as opening a bank account or keeping a diary. The others were asked to write about why someone might want to open a bank account or keep a diary.

From Air And Space Smithsonian Magazine:

In the old days it was straightforward enough. The planet had two corps of astronauts, Soviet and U.S., and to join one, you had to be a military test pilot. But now the rules have changed. You don’t have to be an American or a Russian anymore, and you don’t even have to be a government employee.

In 2004, Burt Rutan and his small company in Mojave, California, Scaled Composites, broke the government monopoly on human spaceflight. The company built SpaceShipOne using the same carbon fiber molding techniques used by airplane homebuilders everywhere, at the ridiculously paltry cost of $25 million. At the controls on its first flight into space sat not a steely-eyed missile man forged in the cold war but a 63-year-old high school dropout from South Africa. “I’m just a guy,” Mike Melvill exulted after SpaceShipOne’s inaugural flight into space. “An old guy!” The implication was inescapable. If he could drive a spaceship, so could anyone.

From The New Scientist:

HOW common are alien Earths - small, rocky planets orbiting at the right distance to be not so hot that water boils and not so cold that it stays frozen? Till now clues have been hard to come by, because surveys have not been sensitive enough to find many such planets.

That should soon change thanks to the Kepler space telescope, which NASA is expecting to launch on 5 March. Its unique positioning in the solar system and unprecedented sensitivity mean that for the first time we will be able to see Earth-size planets in the "habitable zone" of their stars - the region where the temperature on the planet should be right for liquid water to exist at its surface.

The images unravel some of the inner workings of the most efficient solar energy process on earth - photosynthesis. Inside a photosynthetic protein, the sun's energy is efficiently guided across the molecule to drive a chemical reaction that stores energy as food and takes in carbon dioxide. Scientists would very much like to harness this process as they search for new energy solutions to replace fossil fuels. To do this, they need to understand this energy transport process in more detail.

From The Christian Science Monitor:

Like high-def television before it, 3-D technology is ahead of its content, and consumers are hungry.

South Central Los Angeles

In a converted warehouse near one of Los Angeles’s toughest neighborhoods, a coterie of professional “techno-speculators” is playing around with what a growing number of entertainment industry folks hope the future of the small screen will be, namely 3-D.

This is the Entertainment Technology Center at the University of Southern California, where the Home 3D Experience Lab, ETC’s newest brainchild, is currently housed in a bare-bones room. The 3-D lab just opened this past week and isn’t complete yet, meaning the team is still assembling all the various iterations of 3-D as it will be experienced in consumers’ homes. But the fundamentals are in place – glasses, screens, and playback devices – says Bryan Gonzalez, the lab’s technical project specialist.

“For the state of the art in 3-D for the home environment, this is where the industry leaders can gather to discuss where it’s going,” says executive director David Wertheimer. The nonprofit research center is funded by content and technology companies, including nearly all the major film studios.

From Live Science:

Researchers have made an advance toward a long-sought goal of building "invisible electronics" and transparent displays.

The work could eventually lead to better heads-up displays for pilots or even windshield displays and cars, as well as electronic paper that could deliver all the contents of a magazine or a newspaper on one, ever-changing, portable and perhaps even disposable sheet. Another goal: wearable electronic clothing displays.

The scientists, led by Chongwu Zhou and colleagues at UCLA developed tiny, transparent electronic circuits they say are more powerful than similar devices developed in recent years.

The work was detailed in the Jan. 27 issue of ACS Nano, a monthly journal.

In the new study, Chongwu Zhou and colleagues point out that although scientists have previously developed nano-sized transparent circuits, previous versions are limited to a handful of materials that are transparent semiconductors.

Kissing Feels So Pleasurable Due To Hormone Surge, Find Scientists

From The Telegraph:

The reason that kissing feels so pleasurable is that sparks a surge of hormones in our brains, according to new research.

Couples who share a passionate kiss this Valentine's Day will enjoy sensations of relaxation and excitement because of a complex series of chemical processes, as well as their love for their partners.

The study showed that women need more than just a kiss to experience the same chemical high as men - with additional features such as a romantic atmosphere of dimmed lights and mood music also required.

Wendy Hill, professor of psychology at Lafayette College, Pennsylvania began the research to find out why the mundane physical activity of rubbing lips can elicit such a gratifying emotional response.

Her team tested the levels of two hormones, cortisol and oxytocin, in 15 couples before and after holding hands and kissing.

They found that kissing reduced the levels of cortisol, a stress hormone, in both sexes. But levels of oxytocin, a hormone linked to social bonding that they expected to be boosted by kissing, only rose among the men.

From The Guardian:

Breakthroughs in microscopic engineering could boost shelf life of food and increase crop yields.

A controversial scientific revolution that could give packaged foods a dramatically longer shelf life and boost crop growth has "real potential" to help feed a fast-growing world, according to environment secretary Hilary Benn.

New developments in nanotechnology, engineering carried out at a microscopic level, could lead to plastic packaging designed to stop food and drink spoiling by killing bacteria or preventing oxygen getting through the container.

The technology could also be used to enrich food with supplements and preserve vitamins that would otherwise be destroyed as food aged. Farmers could also use it to ensure the slow release of fertilisers at the right time for crops, and to detect threats from pests or pollutants. The technology is, however, highly controversial, with green campaigners arguing that its effects on human health are unknown.

From The Daily Mail:

Researchers have discovered what women are really thinking when they look into a man’s eyes – and it is all about the size of their...pupils.

Women become attracted to men with large pupils just as they are approaching their most fertile time of the month, the study at Edinburgh University found.

Scientists suggest that it may be because it indicates that the man is sexually interested in them and available for mating. Pupil size made no significant difference for the rest of the menstrual cycle.

From McClatchy:

WASHINGTON — It has to do with brown-headed cowbirds and clear-cut forests, lilacs and wildfires, vineyards in the Rhine Valley, marmots, dandelions, tadpoles, cherry trees around the Tidal Basin in Washington and musty old records stuffed in shoe boxes in people's closets and stacked on museum shelves.

As scientists track global warming, they're using sometimes centuries-old data to assess its impact on plants, animals, insects, fish, reptiles and amphibians. Increasingly, they're discovering that it can take only one seemingly insignificant change to disrupt an entire ecosystem.

"People talk about a 1- or 2-degree rise in temperature and it's inconsequential to us. Who cares?" said Greg Jones, an environmental studies professor at Southern Oregon University who's been studying wine grapes. "But in an ecosystem it can have dramatic effects."

From The Christian Science Monitor:

From Minnesota to Texas, wind power sweeps new jobs into old-tech towns.

Cedar Rapids and Estherville, Iowa

Hundreds of workers lost their jobs after the Rockwell-Goss printing press factory closed here in Cedar Rapids in 2001. The hulking empty shell sat idle on the outskirts of the city for four years.

But that was before wind power blew into town, bringing thousands of clean-tech manufacturing jobs to Iowa and the Midwest.

In many cases, the new industry is setting up shop in defunct heavy manufacturing plants, bringing new economic life and vitality to old settings.

Bob Loyd, who once oversaw crews manufacturing the last printing presses to leave the old Rockwell-Goss factory, now manages workers assembling the newest generation of giant wind turbines in the same building.

Curing Baldness Could Be A Step To Organ Regeneration

Deep roots. For a hair follicle to begin a new phase of growth, an elusive group of cells called the hair germ (bright red) must be activated. This progression of images shows that the hair germ begins proliferating (green) before other cells do, suggesting a two-step mechanism.

From The Next Big Future:

Research from Rockefeller University reveals that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide. The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.

So understanding and fixing the stem cells and the replenishment of stem cells in hair follicles could lead to a baldness cure and also to human regeneration of organs.

Scientists are expected to make a decision within days on when the Large Hadron Collider, the broken "Big Bang" machine, will be re-started.

The LHC suffered a catastrophic malfunction soon after being switched on last September amid a fanfare of publicity.

Officials and scientists from the European Organization for Nuclear Research (CERN), which built the £4billion device, have been in talks this week about when to re-start it.

They have also discussed what caused the LHC to grind to a halt and how to prevent similar incidents happening in the future.

CERN have now said that they hope the machine will be up and running in time to deliver the first batch of data for experts to begin experiments by the end of the year.

A final decision on the exact date to switch it back on is expected following a meeting on Monday.

Study: How Money Can Buy Happiness

From Live Science:

You've heard many times that money can't buy happiness. That probably never stopped you from shopping. But a new study suggests you might want to spend more on doing things and less on stuff.

Buying life experiences rather than material possessions leads to greater happiness for both the consumer and those around them, researchers announced today at the annual meeting of the Society for Personality and Social Psychology.

A meal out or tickets to the theater result in increased well-being because they satisfy higher order needs, specifically the need for social connectedness and vitality — a feeling of being alive, the researchers say.

"These findings support an extension of basic need theory, where purchases that increase psychological need satisfaction will produce the greatest well-being," said Ryan Howell, assistant professor of psychology at San Francisco State University.

"Noah's Flood" Not Rooted In Reality, After All?

Some believe that Noah's Ark came to rest on Turkey's Mount Ararat, above. But the ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a January 2009 study says. Photograph by Melik Baghdasaryan/AP/Photolur

From National Geographic:

The ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a new study says.

Researchers generally agree that, during a warming period about 9,400 years ago, an onrush of seawater from the Mediterranean spurred a connection with the Black Sea, then a largely freshwater lake. That flood turned the lake into a rapidly rising sea.

A previous theory said the Black Sea rose up to 195 feet (60 meters), possibly burying villages and spawning the tale of Noah's flood and other inundation folklore.

But the new study—largely focused on relatively undisturbed underwater fossils—suggests a rise of no more than 30 feet (10 meters).

From Nature:

Draft sequence opens window on human relatives.

The entire genome of a 38,000-year-old Neanderthal has been sequenced by a team of scientists in Germany. The group is already extracting DNA from other ancient Neanderthal bones and hopes that the genomes will allow an unprecedented comparison between modern humans and their closest evolutionary relative.

The three-year project, which cost about €5 million (US$6.4 million), was carried out at the Max Planck Institute for Evolutionary Anthropology in Leipzig. Project leader Svante Pääbo will announce the results of the preliminary genomic analysis at the American Association for the Advancement of Science annual meeting in Chicago, Illinois, which starts on 12 February.

Are We Bringing Our Germs to Mars?

From Time Magazine:

Star Trek fans know it as the Prime Directive: that there should be no interference with the internal affairs of other civilizations. (Given the frequency with which captains Kirk, Picard, et. al., violate it, however, the Prime Directive seems more like a Prime Suggestion.) Since human beings have yet to explore very far beyond Earth, pondering an interplanetary noninterference policy of our own may seem a little premature — at least until we've mastered warp drives and phasers.

But in fact, such a directive already exists in some form — the international Outer Space Treaty of 1967, which governs the legal framework for activities in space. Best known for banning governments from putting nuclear weapons into orbit, the treaty also requires space-faring nations to avoid "harmful contamination" of other worlds while exploring the solar system. Human beings have yet to set foot on other planets, so the risk today comes from bacteria that can hitch a ride on unmanned spacecraft like NASA's Mars Phoenix Lander, which arrived on the red planet's surface last May.

From Popular Mechanics:

As nations and regions all over the globe face too much polluted water and too little fresh water, they are turning to some of the largest, most technologically complex projects the world has ever seen. Here, we have compiled five of the biggest and most ambitious. But are they big enough to keep the taps flowing?

The dire statistics are well-known, but deserve repeating: One in six people in the world live without regular access to clean water, according to the United Nations, and one in three lacks access to decent sanitation. Even countries with good water supplies—like the U.S.—will experience trouble sustaining them in the near future, as panelists discussed at the water roundtable PM hosted last fall.

TED: Change The World With $100,000

From CBS News:

CBS Technology correspondent Daniel Sieberg is reporting from the TED conference in Long Beach, Calif.

The concept is simple; it's the execution that requires global collaboration and commitment. Not to mention some serious cash. Along those lines, TED prizes are an award of $100,000 given to a select group of recipients looking to change the world with one idea or "wish." They can use the money as they choose, and at a ceremony here Thursday night the three winners expressed their hopes for the future.

Jill Tarter, founder of SETI or the Search for Extra-Terrestrial Life, encouraged TED attendees and others to imagine ways that every "earthling" could contribute to a growing database of life beyond our planet or our "cosmic company." In real terms, Tarter wants kids to be more involved in the experience of searching or studying the universe, and improve the way information from space is stored and shared with astronomers. Her announcement was preceded by a taped introduction from Sir Richard Branson, who is actively pursuing commercial space travel through his Virgin Galactic project.

Top 5 Most Extreme Exoplanets

From Wired Science:

Searching for planets beyond our solar system is a bit like playing Goldilocks — we keep looking for that one that will be just right to host life. While astronomers haven't found a perfect fit yet, they have found plenty that are too big, too hot, too cold, too dense, too close to their star, or too distant.

The first exoplanet discovery was in 1988, though it was controversial at the time and wasn't officially confirmed until 2003. Over the years, more than 330 extrasolar planets have been found, nearly all of them using indirect methods such as detecting the wobble of a star due to the gravitational pull of an orbiting planet or the slight dimming of the star's light as a planet passes in front of it.

Key Insights Into How New Species Emerge

From Science Digest:

ScienceDaily (Feb. 6, 2009) — A team of researchers are reporting the ongoing emergence of a new species of fruit fly--and the sequential development of a new species of wasp--in the February 6 issue of the journal Science.

Jeff Feder, a University of Notre Dame biologist, and his colleagues say the introduction of apples to America almost 400 years ago ultimately may have changed the behavior of a fruit fly, leading to its modification and the subsequent modification of a parasitic wasp that feeds on it.

The result is a chain reaction of biodiversity where the modification of one species triggers the sequential modification of a second, dependent species.

"It's a nice demonstration of how the initial speciation of one organism opens up an opportunity for another species in the ecosystem to speciate in kind," said Feder. "Biodiversity in essence is the source for new biodiversity."

From Live Science:

Richard Donovan, a 42-year-old from Ireland, is as close to being the real Forrest Gump as anyone.

Running to raise money for a charity called Goal, which works to ease suffering in Darfur, Donovan ran seven marathons on seven continents. If you know your continents, you know that's a challenge. More: He did it in 5 days.

The order of Donovan's insanity, which began Jan. 31:

* Antarctica
* Cape Town, South Africa
* Dubai
* London
* Toronto
* Santiago, Chile
* Sydney, Australia

"What he did was staggering, quite remarkable," John O'Shea, the charity's founder and chief executive, told the news agency AFP.

To prove he's human, Donovan took airline flights between destinations. To keep it real, he flew coach.

Reading This Will Change Your Brain

From Newsweek:

A leading neuroscientist says processing digital information can rewire your circuits. But is it evolution?

Is technology changing our brains? A new study by UCLA neuroscientist Gary Small adds to a growing body of research that says it is. And according to Small's new book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a dramatic shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may ultimately change the human brain as we know it. "Perhaps not since early man first discovered how to use a tool has the human brain been affected so quickly and so dramatically," he writes. "As the brain evolves and shifts its focus towards new technological skills, it drifts away from fundamental social skills."

How You Can Tell A Person's Class: The Wealthy Fidget, Yawn And Generally Appear Rude, Say Researchers

Photo: Body language: Those from wealthier backgrounds tend to appear more distracted than their less well off counterparts

From The Daily Mail:

Fidgeting, yawning and doodling have long been equated with boredom.

But if the person you're speaking to isn't paying attention, they may be rich rather than rude, a study has revealed.

It found that posh people fidget more - making it possible to tell a person's social class by their body language.

Researchers said those born into privilege may feel less of a need to make a good impression and so are more inclined to fidget when talking to other people.

In contrast, their poorer counterparts are anxious to make a good impression and so are more attentive.

Science Found Wanting In U.S. Crime Labs

From International Herald Tribune:

Forensic evidence that has helped convict thousands of defendants for nearly a century is often the product of shoddy scientific practices that should be upgraded and standardized, according to accounts of a draft report by the nation's pre-eminent scientific research group.

The report by the National Academy of Sciences is to be released this month. People who have seen it say it is a sweeping critique of many forensic methods that the police and prosecutors rely on, including fingerprinting, firearms identification and analysis of bite marks, blood spatter, hair and handwriting.

Britannica 2.0 Shows Wikipedia How It's Done

From Times Online:

The 240-year-old Encyclopaedia Britannica has taken a giant leap into the world of Web 2.0 with the launch of a new online version where users can contribute and edit content.

In a move that takes it head to head with Wikipedia, new features on the Britannica site will allow users to edit and contribute articles in return for the glory of having their name attached to the submission.

However, “voyeuristic” Wikipedia fans ought not to get too excited by the changes as all submissions will undergo a strict vetting process and may or may not make the cut, according to Britannica 's president, Jorge Cauz.

“We’re not trying to be a wiki - that’s the last thing we want to be,” Mr Cauz told The Times.

From China View:

SHANGHAI, Feb.1 (Xinhua) -- East Asian astronomers are building the world's largest radio telescope array to see the deep into the galaxy and black holes and more accurately determine the orbits of lunar probes such as China's Chang'e-1.

The array, called the East Asia Very Long Baseline Interferometry (VLBI) consortium, consists of 19 radio telescopes from China, Japan and the Republic of Korea (ROK) that cover an area with a diameter of 6,000 kilometers from northern Japan's Hokkaido to western China's Kunming and Urumqi.

The VLBI technology is widely used in radio astronomy. It combines the observations simultaneously made by several telescopes to expand the diameter and increase magnification.
