From CBS:
Software Could Help Publishers Recover Thousands In Ad Revenue, Study Finds
(AP) Here's another reason for ailing newspaper and magazine publishers to wince: On average, the audience perusing unauthorized online copies of their articles is nearly 1.5 times larger than the readership on their own Web sites, according to a study released Thursday.

However, the problem, flagged by copyright cop Attributor Corp., could turn into a golden opportunity if media companies figure out a way to mine advertising revenue from the traffic flocking to their pirated stories posted on blogs and other sites.

UN: Clouds Of Pollution Threaten Glaciers, Health

From Myway/AP:

BEIJING (AP) - A dirty brown haze sometimes more than a mile thick is darkening skies not only over vast areas of Asia, but also in the Middle East, southern Africa and the Amazon Basin, changing weather patterns around the world and threatening health and food supplies, the U.N. reported Thursday.

The huge smog-like plumes, caused mainly by the burning of fossil fuels and firewood, are known as "atmospheric brown clouds."

When mixed with emissions of carbon dioxide and other gases blamed for warming the earth's atmosphere like a greenhouse, they are the newest threat to the global environment, according to a report commissioned by the U.N. Environment Program.

"All of this points to an even greater and urgent need to look at emissions across the planet," said Achim Steiner, head of Kenya-based UNEP, which funded the report with backing from Italy, Sweden and the United States.

From Science Daily:

ScienceDaily (Nov. 13, 2008) — NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star.

Estimated to be no more than three times Jupiter's mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis (the Southern Fish).

Fomalhaut has been a candidate for planet hunting ever since an excess of dust was discovered around the star in the early 1980s by NASA's Infrared Astronomy Satellite (IRAS).

Why Do We Panic?

From Scientific American:

A better understanding of the path from stress to anxiety to full-blown panic disorder offers soothing news for sufferers

“I was driving home after work,” David reported. “Things had been very stressful there lately. I was tense but looking forward to getting home and relaxing. And then, all of a sudden—boom! My heart started racing, and I felt like I couldn’t breathe. I was sweating and shaking. My thoughts were racing, and I was afraid that I was going crazy or having a heart attack. I pulled over and called my wife to take me to the emergency room.”

David’s fears turned out to be unjustified. An emergency room doctor told David, a composite of several therapy patients seen by one of us (Arkowitz), that he was suffering from a panic attack.

From FOX News/Space.com:

Astronomers have taken what they say are the first-ever direct images of planets outside of our solar system, including a visible-light snapshot of a single-planet system and an infrared picture of a multiple-planet system.

Earth-like worlds might also exist in the three-planet system, but if so they are too dim to photograph.

The other newfound planet orbits a star called Fomalhaut, which is visible without the aid of a telescope. It is the 18th brightest star in the sky.

The massive worlds, each much heftier than Jupiter (at least for the three-planet system), could change how astronomers define the term "planet," one planet-hunter said.

Mysterious Glowing Aurora Over Saturn Confounds Scientists

The northern polar region of Saturn shows both the aurora and underlying atmosphere, as captured by NASA's Cassini spacecraft

From The Daily Mail:

A stunning light display over Saturn has stumped scientists who say it behaves unlike any other planetary aurora known in our solar system.

The blueish-green glow was found over the ringed planet's north polar region just like Earth's northern lights.

It was discovered by the infrared instruments on NASA's Cassini spacecraft.

'We've never seen an aurora like this elsewhere,' said Tom Stallard, a scientist working with Cassini data at the University of Leicester.

'This aurora covers an enormous area across the pole. Our current ideas on what forms Saturn's aurora predict that this region should be empty, so finding such a bright aurora here is a fantastic surprise.'

From The International Herald Tribune:


Barack Obama's Internet-fueled campaign has transformed the way Americans choose a president. Now, the president-elect's administration plans to change the way Americans - and government - use technology.

If Obama gets his way, all Americans would have broadband Internet access, whether they live in big cities or remote villages. Online life would be safer, with better defenses against cybercriminals. And there would be greater access to government, with online services to let anyone question members of the president's cabinet or track every dime of the U.S. budget.

"I think it's not going to happen in the first 100 days, but I think a lot of this can happen in the first term," said Ben Scott, policy director of Free Press, a media reform organization based in Washington.

Global Warning: We Are Actually Heading Towards A New Ice Age, Claim Scientists


From Daily Mail:

It has plagued scientists and politicians for decades, but scientists now say global warming is not the problem.

We are actually heading for the next Ice Age, they claim.

British and Canadian experts warned the big freeze could bury the east of Britain in 6,000ft of ice.

Most of Scotland, Northern Ireland and England could be covered in 3,000ft-thick ice fields.

The expanses could reach 6,000ft from Aberdeen to Kent – towering above Ben Nevis, Britain’s tallest mountain.

Turning Tequila Into Diamonds

Image from The Tequila-Man

From Foreign Policy Blog:

Tequila doesn't just produce hangovers any more. Under the right conditions, the alcohol can be turned into diamonds.

Researchers at the National Autonomous University of Mexico, experimenting with making thin films of diamond from organic solutions, decided to conduct their tests using a "pocket-size bottle of cheap white tequila." They heated the tequila to 1,470ºF, breaking down its molecular structure. The resulting carbon film, upon close examination, had formed into an almost perfect diamond structure. Tequila's mix of 40 percent ethanol and 60 percent water is the reason it serves as the perfect compound for creating synthetic diamonds.

A New Congress, A New Approach To Technology?

From CNET News:

Presidential elections may capture the public's attention, as Barack Obama's victory did last week, but the less glamorous work in the U.S. Congress tends to prove more important for technology topics.

In general, much of today's current congressional leadership will continue unchanged into the next, albeit with some complications such as Obama's departure and some narrow Senate races including Minnesota's. Whatever the outcome, Democrats are likely to be newly emboldened and may be eager to approve legislation that stalled in the 110th Congress, including spyware regulations and a shield law that would protect some bloggers.

Google Hits To Warn Of Flu Epidemics


From The Guardian:

Search engine to use online queries to predict health trends before official health bodies

Google already has a window into our souls through our internet searches and it now has insight into our ailing bodies too.

The internet giant is using its vast database of individual search terms to predict the emergence of flu up to two weeks before government epidemiologists.

Google Flu Trends uses the tendency of people to seek online help for their health problems.

By tracking searches for terms such as 'cough', 'fever' and 'aches and pains' it claims to be able to accurately estimate where flu is circulating.

Google tested the idea in nine regions of the US and found it could accurately predict flu outbreaks between seven and 14 days earlier than the federal centres for disease control and prevention.

Google hopes the idea could also be used to help track other diseases. Flu Trends is limited to the US.

NASA's Mars Rover Spirit Imperiled By Dust Storms

This image of NASA's Mars Exploration Rover Spirit from August 2005 shows the solar panels still gleaming in the Martian sunlight and carrying only a thin veneer of dust a year and a half after the rover landed and began exploring the red planet in January 2004. NASA / JPL-Caltech / Cornell University

From L.A. Times:

The craft is dangerously low on power because of dust covering its solar arrays. News of the problem comes a day after NASA declared an end to the Phoenix polar mission.

Massive Martian dust storms are threatening the survival of NASA's Spirit rover, which has been exploring Mars for almost five years but is dangerously low on power.

Spirit last communicated with Earth on Sunday, when it reported that its solar arrays had produced just 89 watt-hours of energy, which is much less than the rover uses in a day.

It's also the least amount of power that either Spirit, or its twin, Opportunity, has produced over the entire life of the mission on Mars, which began in January 2004.

How Much Can We Blame DNA For Who We Are?

From International Herald Tribune:

I owe an apology to my genes. For years I offhandedly blamed them for certain personal defects conventionally associated with one's hereditary starter pack - my Graves' autoimmune disease, for example, or my hair, which looks like the fibers left behind on the rim of an aspirin bottle after the cotton ball has been removed, only wispier.

Now it turns out that genes, per se, are simply too feeble to accept responsibility for much of anything. By the traditional definition, genes are those lineups of DNA letters that serve as instructions for piecing together the body's proteins, and, I'm sorry, but the closer we look, the less instructive they seem, less a "blueprint for life" than one of those disappointing two-page Basic Setup booklets that comes with your computer, tells you where to plug it in and then directs you to a Web site for more information.

Global Warming Link To Amphibian Declines In Doubt


From E! Science News:

Evidence that global warming is causing the worldwide declines of amphibians may not be as conclusive as previously thought, according to biologists. The findings, which contradict two widely held views, could help reveal what is killing the frogs and toads and aid in their conservation. "We are currently in the midst of a sixth mass extinction event," said Peter Hudson, the Willaman professor of biology at Penn State and co-author of the research study. "And amphibians are bearing the brunt of the problem."

Studies suggest that more than 32 percent of amphibian species are threatened and more than 43 percent face a steep decline in numbers.

Much of the massive declines associated with amphibians appear to be centered in places such as Central America and Australia, said Hudson. "It appears to be linked to a chytrid fungus -- Batrachochytrium dendrobatidis (Bd) -- which we did not know affected frogs," he added.

From Discovery:

Nov. 12, 2008 -- Generating wind power at sea may disturb ocean currents and marine ecosystems, according to a new study.

Offshore wind farms are common in Europe; Denmark, The Netherlands, and the United Kingdom all have several active installations. Wind power in the United States is currently confined to dry land, but three installations are planned off the coast of New Jersey, Rhode Island, and Delaware, totaling about 1,500 megawatts of generating capacity.

Extracting energy from wind changes regional air currents, which can in turn affect how the nearby ocean circulates, according to Goran Brostrom of the Norwegian Meteorological Institute in Oslo.

Two-Fifths Of Earth's Population at Risk

From Science Blog:

Vibrio cholerae. Cholera. One of the most aggressive water-borne infections, cholera can kill within 24 hours, and has caused seven pandemics in history. It occurs in over 60 countries worldwide. Currently, the World Health Organization(WHO) has warned that cholera is a serious risk in the Democratic Republic of Congo, where there have already been 1,000 cases since October. Of course, most Americans are unfamiliar with cholera since the last outbreak in the U.S. was in 1911. And I don't think any of us were around for that.

Cholera is a bacterial infection of the intestine that comes from consuming infected food or water. Symptoms begin with sever diarrhea and vomiting, which then lead to dehydration. Blood pressure falls, cramps develop in the legs and abdomen, and then body temperature drops as organ failure occurs. Not a pretty picture. There is hope however.

How Floating 'Energy Islands' Could Power the Future

Three Energy Islands are shown connected in this artist rendering. Credit: Energy Island

From Live Science:

Editor's Note: Each Wednesday LiveScience examines the viability of emerging energy technologies — the power of the future.

The ocean harbors abundant energy in the form of wind, waves and sun. All of these could be sampled on something called an Energy Island: a floating rig that drills for renewables instead of petroleum.

The concept is the brainchild of inventor Dominic Michaelis. He was originally unsatisfied with the slow progress in developing ocean thermal energy conversion (OTEC), a process in which cold water is pumped up from the deep ocean to generate electricity.

"Nothing new was happening with OTEC, so I thought why not bring other marine energy technologies on board?" Michaelis said.

A History Of Microsoft Windows


From Wired News:

Windows 1.0

The world's most ubiquitous operating system was not always so. The evolution of Windows was often uncertain and precarious. Its success was symbiotic with advancements in processor speed and memory capacity, and Microsoft relied heavily on third-party software to bridge the gap between concept and consumer. Tour the 23-year history of the Windows OS through these screenshots.

Left: Microsoft's first graphical user interface -- Windows 1.0 -- wasn't released until November 1985, nearly two years after Apple introduced the Mac. Due to legal issues with Apple, Gates couldn't include key features like overlapping windows and a trash can. Looking at it now, it's not surprising it was a flop. Windows 1.0 was more an extension of MS-DOS than its own operating system, but it did allow limited multitasking and mouse support.

Spammers are turning a profit despite only getting one response for every 12.5m e-mails they send, finds a study.

By hijacking a working spam network, US researchers have uncovered some of the economics of being a junk mailer.

The analysis suggests that such a tiny response rate means a big spam operation can turn over millions of pounds in profit every year.

It also suggests that spammers may be susceptible to attacks that make it more costly to send junk mail.

IBM To Help Build Broadband Network In Power Lines


From Yahoo News Finance/AP:

Broadband over power lines gets a needed endorsement from a big player in computing

NEW YORK (AP) -- IBM Corp. is throwing its considerable weight behind an idea that seemed to have faded: broadband Internet access delivered over ordinary power lines.

The technology has been around for decades, but most efforts to implement the idea on a broad scale have failed to live up to expectations.

Now, with somewhat scaled-back goals, improved technology, and a dose of low-interest federal loans, IBM is partnering with a small newcomer called International Broadband Electric Communications Inc. to try to make the idea work in rural communities that don't have other broadband options.

27.7 Billion Gallons Of Ethanol To Be Produced By 2012

(Photo from Device Daily)

From Device Daily:

Nowadays, the Earth is getting more and more polluted because of fossil fuels. We already know that, but still our planet suffers even more. Although it’s not the best solution, ethanol could provide a better option as an alternate fuel as anything is better than gasoline or oil. The world ethanol market is expected to reach 27.7 billion gallons by 2012 as the interest in fuel-ethanol is rising thanks to the ban on MTBE in several countries.

Ethanol is also receiving help from many governments which have strict rules and they have begun to demand the presence of ethanol in fuels. Unsurprisingly, the world leader in the production of ethanol will be the USA which has mandated a use of 8 billion gallons of ethanol by 2012. The US is aiming to cut down greenhouse gas emissions, and to reduce their dependence on oil therefore ethanol will be an important part when renewable fuels will take over.

Technology Works On Perfect Banana

From the Globe And Mail Science:

ROTTERDAM, Netherlands — It isn't easy to keep a banana yellow.

To get it to market ripe but unblemished by brown sugar spots takes careful timing, a slight fiddling with nature's rhythms and a delivery system that is increasingly computer-driven and technical.

The perfect banana used to be a rare and precious find, but technology is changing that. From the tree in the sweltering tropics to the grocery rack in the frigid north, scientists are seeking new ways to strengthen the food chain and extend the shelf life of perishables so they reach distant consumers as if freshly picked.

Commercially, the goal is to satisfy a demand for quality food anywhere, any time, and at maximum profit.

But the implications go further: As the world's population expands 50 per cent – to nine billion – by mid-century, food security will become critical. The wild rise in food prices that peaked last July, with staples doubling or tripling in cost over three years, underscored the consequences of shortages, whether real or perceived.

As cities grow and wealth expands, more people eat meat, dairy and fresh products.

“That requires a totally different way of approaching agriculture. You have chains of total food systems,” said Rudy Rabbinge, chairman of the Science Council Consultative Group on International Agricultural Research, an alliance of agricultural bodies worldwide.

From Astrobiology:

Oldest Evidence for Life in Doubt

Chemical biomarkers in ancient Australian rocks, once thought to be the oldest known evidence of complex life on Earth, may have infiltrated long after the sediments were laid down, new analyses suggest.

The evidence was based on biomarkers - distinctive chemical compounds produced today by modern-day relatives of cyanobacteria and other complex life forms. In 1999, a team of researchers contended that the biomarkers in the 2.7-billion–year-old rocks pushed back the origins of cyanobacteria by at least 550 million years and of eukaryotes by about a billion years.

Although some scientists interpret the new findings, published in the Oct. 23 Nature, as disproving the older dates, others contend that the results still allow for the presence of the organisms or their kin at that time.

What Happens If You Eat Dog Food?


From Live Science:

If you just eat a little bit of dog food, probably nothing will happen. But you don't really know that for sure because dog food is not subjected to the same health and safety regulations that human food is required to have.

In the United States, the Food and Drug Administration (FDA) is responsible for setting human food safety guidelines to prevent sickness due to contaminated or improperly handled products. In addition, the FDA is responsible for ensuring that food product labels are accurate in terms of ingredient listing and nutritional content.

Dog food does not have these same strict rules that human food has. Although most dog food contains the same basic components that are in people food — protein, carbohydrates and fats — the proportions of these ingredients are different than in human food and can be harmful if ingested in significant quantities or for prolonged periods of time. The same is true if you feed a dog the wrong proportion of these nutrients by giving it an unbalanced human diet.

Lebanon Finds 2,900 Year Old Phoenician Remains

Archaeologists work on earthenware potteries found at an excavation site in the port city of Tyre, southern Lebanon November 12, 2008. (Haidar Hawila/Reuters)

From Yahoo News/Reuters:

BEIRUT (Reuters) – Lebanese and Spanish archaeologists have discovered 2,900-year-old earthenware pottery that ancient Phoenicians used to store the bones of their dead after burning the corpses.

They said more than 100 jars were discovered at a Phoenician site in the southern coastal city of Tire. Phoenicians are known to have thrived from 1500 B.C. to 300 B.C and they were also headquartered in the coastal area of present-day Syria.

"The big jars are like individual tombs. The smaller jars are left empty, but symbolically represent that a soul is stored in them," Ali Badawi, the archaeologist in charge in Tire, told Reuters Wednesday.

Badawi and a Spanish team from the Pompeu Fabra University in Barcelona have been excavating at the Phoenician site for years. The site was first discovered in 1997 but archaeologists have only been able to dig up 50 square meters per year.

Sunlight Has More Powerful Influence On Ocean Circulation And Climate Than North American Ice Sheets

From Watts Up With That?

From Physorg.com: A study reported in today’s issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods.

The distribution of sunlight, rather than the size of North American ice sheets, is the key variable in changes in the North Atlantic deep-water formation during the last four glacial cycles, according to the article. The new study goes back 425,000 years, according to Lorraine Lisiecki, first author and assistant professor in the Department of Earth Science at the University of California, Santa Barbara.

Lisiecki and her co-authors studied 24 separate locations in the Atlantic by analyzing information from ocean sediment cores. By observing the properties of the shells of tiny marine organisms, called foraminifera, found in these cores, they were able to deduce information about the North Atlantic deep water formation. Scientists can discern historical ocean temperature and circulation patterns through the analysis of the chemical composition of these marine animals.

From Science Daily:

ScienceDaily (Nov. 11, 2008) — Illustrating the power of submillimetre-wavelength astronomy, an APEX telescope image reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimetre light is the key to revealing some of the coldest material in the universe, such as these cold, dense clouds.

The region, called RCW120, is about 4200 light years from Earth, towards the constellation of Scorpius. A hot, massive star in its centre is emitting huge amounts of ultraviolet radiation, which ionises the surrounding gas, stripping the electrons from hydrogen atoms and producing the characteristic red glow of so-called H-alpha emission.

From Live Science:

Having a bad hair day? You're excused. After all, hair has its origins in stuff that used to make just claws. Research now suggests that hair of all kinds extends much further back into evolutionary time, with birds and reptiles having genes for hair proteins.

Scientists previously had thought hair was just a mammalian thing, with its evolution cropping up after the mammalian lineage split from the reptilian lineage. The first mammals arose on Earth about 210 million years ago. Humans, birds and reptiles have a common ancestor that goes back some 300 million years, said researcher Leopold Eckhart of the Medical University of Vienna in Austria.

too acidic by 2030 (Source: iStockphoto)

From ABC News (Australia):

Australian researchers have discovered that the tipping point for ocean acidification caused by human-induced CO2 emissions is much closer than first thought.

Scientists from the University of New South Wales (UNSW) and CSIRO looked at seasonal changes in pH and the concentration of an important chemical compound, carbonate, in the Southern Ocean.

The results, published in today's Proceedings of the National Academy of Science, show that these seasonal changes will actually amplify the effects of human carbon dioxide emissions on ocean acidity, speeding up the process of ocean acidification by 30 years.

Dr Ben McNeil, senior research fellow at the UNSW's Climate Change Research Centre, says the ocean is an enormous sink for CO2, but unfortunately this comes at a cost.

BEIJING (Reuters) – Wild animals are climbing back onto Chinese plates after the deadly SARS virus made some diners wary, and booming demand for traditional medicine is also threatening some plants, environmentalists said on Wednesday.

Nearly half of urbanites had consumed wildlife in the past 12 months, either as food or medicine, with rich and well educated Chinese most likely to tuck into a wild snake or turtle, a survey of urbanites in six cities found.

From Yahoo News/Reuters:

CAPE CANAVERAL, Florida (Reuters) -- Countdown clocks at the Kennedy Space Center began ticking down on Tuesday toward Friday's launch of space shuttle Endeavour on a mission to outfit the International Space Station for an expanded live-aboard crew.

Liftoff is targeted for 7:55 p.m. EST (0055 Saturday GMT). At a news conference on Tuesday, managers said the shuttle was in good shape for launch.

"We haven't had a launch for a while so we're really excited to be back in the saddle," said NASA's Jeff Spaulding, a manager overseeing preparations for shuttle Endeavour's flight.

Search Engine With Roots In Genomics Unlocks Deep Web


From Wired/Epicenter:

A research-focused search engine founded by Human Genome Project scientists is claiming to go where even Google doesn't tread: the deep web.

DeepDyve is designed to search the 99 percent (they say, citing a study from UC Berkeley) of hits not picked up by other search engines, which return pages based largely on interpretations of popularity and work only if a page is findable. Content hidden behind paywalls or that is not linked to enough sites to gain page rank remains obscure, but often contains the source material required for serious research.

From The Guardian:

New figures show 26% of all sharks, rays and related species in the north-east Atlantic are threatened with extinction

More than a quarter of sharks and rays in the north-east Atlantic face extinction from overfishing, conservationists warned today.

A "red list" report from the International Union for Conservation of Nature (IUCN) found that 26% of all sharks, rays and related species in the regional waters are threatened with extinction. Seven per cent are classed as critically endangered, while a fifth are regarded as "near-threatened".

The total number of at-risk species may well be higher because scientists lack of sufficient information to assess the populations of more than a quarter (27%) of them, the report adds. Many are slow-breeding fish that are especially vulnerable to fisheries.

Darwin's Beagle To Sail Again

Vessel of knowledge: The original HMS Beagle on which Charles Darwin sailed. A replica is being built to research the effects of plankton on the world's oceans

From The Daily Mail:

It was the ship that carried Charles Darwin to the Galapagos Islands nearly 180 years ago, enabling him to make his breakthrough on the theory of evolution.

Now another HMS Beagle will depart on a new voyage of scientific discovery - this time with the help of sat-nav, engines and guidance from space.

The Beagle Trust plans to build a £5 million replica of the 19th-century vessel and use it to research the effects of plankton on the world's oceans.

It will be guided to algae blooms across the globe with the help of Nasa astronauts aboard the International Space Station.

The charity has finalised its plans and is currently raising funds for its project, scheduled to begin construction within months.

'We are making a lot of progress, and I'm confident we will begin building next year, then set sail in 2010,' said project director Peter McGrath.

The original HMS Beagle took scientist and naturalist Darwin around the world between 1831 and 1836.

Why Veins Could Replace Fingerprints And Retinas As Most Secure Form Of ID

Hitachi's finger vein authentication system represents a decade's worth of development and improvement and the technology has already been included in computers, ATMs and used for cardless payment authorization. Every finger has a vein configuration that is unique to it, much in the same way that every fingerprint is unique, and those veins are able to be read by near-Infrared light coupled with image sensors.

From Times Online:

Forget fingerprinting. Companies in Europe have begun to roll out an advanced biometric system from Japan that identifies people from the unique patterns of veins inside their fingers.

Finger vein authentication, introduced widely by Japanese banks in the last two years, is claimed to be the fastest and most secure biometric method. Developed by Hitachi, it verifies a person's identity based on the lattice work of minute blood vessels under the skin.

Easydentic Group, a European leader in the biometric industry based in France, has announced that it will be using Hitachi's finger vein security in a range of door access systems for the UK and European markets.

Will the Opening of the Northwest Passage Transform Global Shipping Anytime Soon?


From National Geographic:

With the melting of Arctic Ocean ice, the fabled waterway between Europe and Asia has been open to shipping the past two summers--or has it?

It is said that the Inuit have many words for snow, but when it comes to the Northwest Passage only one type of frozen water matters: multiyear ice. It can slice through the hull of a ship like a knife through butter and it persists in the passage's waters despite unprecedented warming in the Arctic Ocean, thwarting shippers in search of a shortcut between Europe and Asia.

The fabled Northwest Passage has made headlines ever since it thawed last year for the first time. For three centuries the quest for an expedited route between the Atlantic and Pacific oceans rivaled today's space race, with European superpowers vying for the prize. Hundreds of sailors and countless expeditions ventured into Canada's Arctic waters, including such naval luminaries as Sir Francis Drake, Captain James Cook and the ill-fated Henry Hudson, who left his name—and lost his life—on the Canadian bay that marks its entrance.

Where Do Science Supermachines Go When They Die?

From The New Scientist:

LIKE a man hoping to find a second-hand sports car at a knockdown price, Lon Morgan used to regularly peruse the for-sale ads in Commerce Business Daily. Then one day in 1995, Morgan saw exactly what he had been looking for and submitted a bid. Three weeks later, Morgan and his company International Isotopes were the proud owners of parts from the world's biggest atom smasher for the princely sum of $4.5 million.

Morgan had bought part of the defunct Superconducting Super Collider, a behemoth of a machine designed to search for the much vaunted Higgs boson, aka the God particle, which is supposed to give all other particles their mass. When funding for the 87-kilometre-round SSC was slashed in 1993 a cool $2 billion had already been spent. Now the huge tunnels in Waxahachie, Texas, sat dark and empty. Since the parts for the accelerator had never actually been assembled into a working machine, they sat crated up in a warehouse, awaiting their new owner and their new destiny.

Fast Food Made Up Mostly of Corn

From The National Geographic:

If you are what you eat, most Americans are an ear of corn, new research suggests.

A chemical analysis of popular fast foods reveals that some form of the grain appears as a main ingredient in most items—especially beef.

The researchers examined the molecular makeup of hamburgers, chicken sandwiches, and french fries purchased from three fast food chains in six U.S. cities.

"Out of the hundreds of meals that we bought, there were only 12 servings of anything that did not go straight back to a corn source," said study lead author Hope Jahren, a geobiologist at the University of Hawaii in Honolulu.

Corn's dominance in the nation's fast food is well known, "but the [chemical analysis] really bring it home in a way that hasn't been brought home before," said Craig Cox, Midwest vice president for the nonprofit Environmental Working Group.

Now: The Rest Of The Genome

From The International Herald Tribune:

Over the summer, Sonja Prohaska decided to try an experiment. She would spend a day without ever saying the word "gene." Prohaska is a bioinformatician at the University of Leipzig in Germany. In other words, she spends most of her time gathering, organizing and analyzing information about genes. "It was like having someone tie your hand behind your back," she said.

But Prohaska decided this awkward experiment was worth the trouble, because new large-scale studies of DNA are causing her and many of her colleagues to rethink the very nature of genes. They no longer conceive of a typical gene as a single chunk of DNA encoding a single protein. "It cannot work that way," Prohaska said. There are simply too many exceptions to the conventional rules for genes.

If You Love Wind Power (And Solar Power), You’d Better At Least Like Transmission.

Sales bookings last year for Bob Chew and his company SolarWrights were $5.9 million, more than double the year before. He expects to hit $20 million this year.

From New York Times/Science :

If you love wind power (and solar power), you’d better at least like transmission. This was originally recited to me as kind of an energy-wonk joke. But it’s no laughing matter, as my colleague Matt Wald points out in an article today on new evidence that the country’s grid is already stretched to the limit and unlikely to be able to handle bigger, intermittent pulses of electricity from wind turbines and big solar-power arrays.

Here’s the lede:

WASHINGTON — Adding electricity from the wind and the sun could increase the frequency of blackouts and reduce the reliability of the nation’s electrical grid, an industry report says. The North American Electric Reliability Corporation says in a report scheduled for release Monday that unless appropriate measures are taken to improve transmission of electricity, rules reducing carbon dioxide emissions by utilities could impair the reliability of the power grid. The corporation is the industry body authorized by the federal government to enforce reliability rules for the interlocking system of electrical power generation and transmission.

An Atomic Solution To The Energy Crisis

Image from Clean Technica

From Fabius Maximus:

Great progress has been made over the decades since America built its last atomic power plant. These solutions arrive just in time to provide clean and relatively inexpensive energy as we convent from liquid fuels (oil, natural gas) after Peak Oil — sometime in the next ten years or so.

This is a brief update about the prospects for atomic power. For more information about new energy sources, see the FM reference page about Energy.

Small Nuclear Power Reactors

The World Nuclear Association has some excellent materials about small nukes, the cutting edge of the next atomic revolution. The following are excerpts from a July 2008 report.
