From FOX News:

HOUSTON — A spacewalking astronaut accidentally let go of her tool bag Tuesday after a grease gun inside it exploded, and helplessly watched as the tote and everything inside floated away.

It was one of the largest items ever to be lost by a spacewalker, and occurred during an unprecedented attempt to clean and lube a gummed-up joint on a solar panel.

Heidemarie Stefanyshyn-Piper was just starting to work on the joint when the mishap occurred.

She said her grease gun exploded, getting the dark gray stuff all over a camera and her gloves. While wiping off herself, the white, backpack-size bag slipped out of her grip, and she lost all her other tools.

"Oh, great," she mumbled.

Hi-Tech Weaponry Battles Piracy On The High Seas

This Saudi Arabian oil tanker, the Sirius Star, was captured by pirates on 16 November 2008, off the coast of Somalia (Image: Caters News / Rex Features)

From New Scientist:

SVEN ERIK PEDERSEN accelerated his 9900-tonne ship to full speed and swung the helm hard over - not the usual way to treat a luxury cruise liner, but then the captain was in an unusual situation. His vessel, the Seabourn Spirit, had just been hit by a rocket-propelled grenade. One of his crew had been wounded by shrapnel, 151 passengers were in danger, and heavily armed pirates in two fast motor boats were attempting to board his ship...

If you imagined that maritime piracy died out with Captain Kidd and the other seafaring scoundrels of the 18th century, the recent attack on the Seabourn Spirit should put you straight. And forget silly notions of wooden legs, treasure maps and grog. Modern-day pirates come equipped with supercharged speedboats, large-calibre weaponry and all the radio intercept technology they need to identify and locate valuable ocean-going booty.

British Doctors Help Perform World's First Transplant Of A Whole Organ Grown In Lab

Claudia Castillo underwent an operation to replace her windpipe with a bioengineered replacement after tuberculosis had left her with a collapsed lung (Photo from The Independent)

From The Telegraph:

British doctors have helped to perform the world's first transplant of a whole organ grown from stem cells, signalling a significant medical breakthrough.

Surgeons replaced the damaged windpipe of Claudia Castillo, a 30-year-old mother of two, with one created from stem cells grown in a laboratory at Bristol University.

Because the new windpipe was made from cells taken from Ms Castillo's own body, using a process called "tissue engineering", she has not needed powerful drugs to prevent her body rejecting the organ.

New Evidence Surfaces Of David's Kingdom

From San Francisco Chronicle:

Khirbet Qeiyafa, Israel -- For 3,000 years, the 12-foot high walls of an ancient city have been clearly visible on a hill towering above the Valley of Elah where the Bible says David slew Goliath.

But no one has ever linked the ruins to the city mentioned in the First Book of Samuel's famous account of the legendary duel and the victory of the Israelites - until now. On Tuesday, Hebrew University archaeology Professor Yosef Garfinkel will present compelling evidence to scholars at Harvard University that he has found the 10th century biblical city of Sha'arayim, Hebrew for "Two Gates." Garfinkel, who made his startling discovery at the beginning of this month, will also discuss his findings at the American Schools of Oriental Research conference hosted by Boston University on Thursday.

Scientists Find Facial Scars Increase Attractiveness

From E! Science News:

Men with facial scars are more attractive to women seeking short-term relationships, scientists at the University of Liverpool have found. It was previously assumed that in Western cultures scarring was an unattractive facial feature and in non-Western cultures they were perceived as a sign of maturity and strength. Scientists at Liverpool and Stirling University, however, have found that Western women find scarring on men attractive and may associate it with health and bravery.

Researchers investigated how scarring might impact on mate choice for men and women seeking both long-term and short-term relationships. They found that women preferred men with facial scars for short-term relationships and equally preferred scarred and un-scarred faces for long-term relationships. Men, however, regarded women with and without facial scars as equally attractive for both types of relationship.

Prehistoric Family Values

From Science Magazine:

When Barack Obama moves into the White House in January, he'll bring his wife and children with him. The nuclear family is not only as American as apple pie but also the cultural norm in most societies across the world. New genetic and chemical analyses of 4600-year-old burials in Germany suggests that family togetherness has deep roots, going back at least as far the beginnings of agriculture in Europe.

Before humans settled down and began to farm, they lived as nomadic hunters and gatherers. Many anthropologists have assumed, based on observations of sometimes polygamous modern-day hunter-gatherers, that the basic social unit of early humans was the band or tribe rather than the family. Figuring out when the nuclear family became central to human social organization has been difficult. Archaeologists have dug up thousands of skeletons at early farming sites across the Near East and Europe, and many of them are buried together in ways that might suggest family ties.

Future Of The U.S. Space Program In Obama's Hands

UP IN THE AIR? Ares rockets, components of the Constellation program, are shown in this artist's conception. Given budgetary and manpower constraints, the future of Constellation, currently scheduled to begin service in 2015, may depend on the future of the space shuttle, which could be retired in 2010. NASA/MSFC

From Scientific American:

A decision must be made by the next chief executive soon on the space shuttle's fate, for starters

As the moments tick away before tonight's scheduled launch of the space shuttle Endeavour to the International Space Station (ISS), another countdown is underway: Only a handful of launches remain before the shuttle program's scheduled retirement in 2010. When President-elect Barack Obama takes office two months from now, he and his aides will need to decide quickly whether or not to hold to that date, a determination that will have major implications for the future of U.S. space exploration.

The U.S. Government Accountability Office (GAO), Congress's investigative arm, has identified the shuttle's future as one of the most urgent issues facing the incoming Obama administration. "NASA has already begun the process of shutting down production and transitioning people, equipment and resources to new endeavors," GAO director of acquisition and sourcing management Cristina Chaplain says. She adds that the longer the decision is delayed, the more difficult it will be to keep operating the shuttle safely and cost-effectively. "Moreover, putting off a decision may hamper the transition itself and keep NASA from pursuing new space transportation development," Chaplain wrote in an e-mail.

A new plan is raising eyebrows in the conservative whisky industry

At the New York WhiskyFest this week, nobody wanted to talk much about technological innovations in the industry. Most of the whisky professionals I asked assured me that there was no such thing as innovation at their tradition-steeped distillery -- they were doing everything the same way it had been done for generations, thank you very much. Some distillers seemed put out that their companies had recently embraced such cutting-edge twentieth-century technology as labelling barrels with bar codes. The marketing side of the business is innovating to beat the band -- look for a new Irish whiskey called Feckin and a new rye called (rī)1 coming soon to bars near you -- but the production side remains defiantly old-fangled.

From Live Science:

Editor's Note: "The Energy Debates" is a LiveScience series about the pros, cons, policy debates, myths and facts related to various alternative energy ideas. We invite you to join the debate by commenting directly on each article.

The Facts

Wind farms harness the wind's energy to generate electricity. Wind energy actually comes mainly from the sun. When solar energy heats up the atmosphere, hot air rises while cooler air swirls down to replace it. This movement results in wind.

Wind turbines possess massive rotors typically 160 to 300 feet (48 to 91 meters) in diameter. A wind turbine inland can generate 1.5 to 2.5 megawatts, while one located offshore amid mighty coastal winds could reach 5 megawatts, although constructing turbines in the water and keeping them up in the face of ocean waves and corrosive seawater presents challenges. Altogether, banks of turbines on a wind farm can produce anywhere from 100 to 800 megawatts.

Variable Electric Generator Improves Wind Power Efficiency

(Photo form Talking Tourism)

From Future Pundit:

An interesting article in MIT's Technology Review reports on a generator for wind turbines that can harvest electric power over a wider range of wind speeds.

ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent.

The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically.

Marine Dead Zones Set To Expand Rapidly

Oxygen content of the world's oceans. Regions with low oxygen are shown in red. IFM-GEOMAR

From Nature:

Rising levels of carbon dioxide could increase the volume of oxygen-depleted 'dead zones' in tropical oceans by as much as 50% before the end of the century — with dire consequences for the health of ecosystems in some of the world's most productive fishing grounds.

At depths between several tens and hundreds of metres, large parts of the tropical oceans are poorly supplied with dissolved oxygen, and are therefore hostile to most marine life. Scientists suspect that these zones are sensitive to climate change, but previous studies have arrived at conflicting conclusions regarding exactly how and why a more CO2-rich world affects oceanic oxygen content.

Artificial Diamonds - Now Available in Extra Large

From The New Scientist:

Diamonds are a girl's best friend, they say - and soon they could be every girl's best friend.

A team in the US has brought the world one step closer to cheap, mass-produced, perfect diamonds. The improvement also means there is no theoretical limit on the size of diamonds that can be grown in the lab.

A team led by Russell Hemley, of the Carnegie Institute of Washington, makes diamonds by chemical vapour deposition (CVD), where carbon atoms in a gas are deposited on a surface to produce diamond crystals.

The CVD process produces rapid diamond growth, but impurities from the gas are absorbed and the diamonds take on a brownish tint.

These defects can be purged by a costly high-pressure, high-temperature treatment called annealing. However, only relatively small diamonds can be produced this way: the largest so far being a 34-carat yellow diamond about 1 centimetre wide.

From Science Daily:

ScienceDaily (Nov. 15, 2008) — An unusual microorganism discovered in the open ocean may force scientists to rethink their understanding of how carbon and nitrogen cycle through ocean ecosystems. A research team led by Jonathan Zehr, professor of ocean sciences at the University of California, Santa Cruz, characterized the new microbe by analyzing its genetic material, even though researchers have not been able to grow it in the laboratory.

Zehr said the newly described organism seems to be an atypical member of the cyanobacteria, a group of photosynthetic bacteria formerly known as blue-green algae. Unlike all other known free-living cyanobacteria, this one lacks some of the genes needed to carry out photosynthesis, the process by which plants use light energy to make sugars out of carbon dioxide and water.

The Consequence Of A Failed Electricity Policy

Get Ready For Rolling Brownouts And Huge Hikes
In Electricity Prices -- Q and O

Forbes warns us:

If you think runaway oil prices are upsetting, just wait for what's in store for electricity. Similar forces are in play. Demand is rising fast; supply is not. The cost to get coal and natural gas out of the ground is going up, and to that expense must be added the cost of the carbon permits that Congress and the presidential candidates are contemplating. Environmentalists are getting power plants scotched. China is sucking up energy. Leave such dynamics in play long enough, and price spikes in electricity follow. But that's just the beginning. We may be facing brownouts (voltage reductions) and even rolling blackouts.

Price shocks are already a part of the system says the article:

Price shocks are already occurring. In May, long before peak summer demand, the wholesale price of juice jumped twofold in Texas, to $4 per kilowatt-hour, 25 times the average retail rate in the country. Prices exceeded the allowed rate of $2 for seven days and threatened the viability of power resellers who contracted to deliver cheap rates to consumers. New Yorkers may suffer a summer of price discontent if regulators are right about peak wholesale prices jumping by up to 90%.

Catastrophic tsunamis result from undersea earthquakes or landslides, and when earthquake-generated tsunamis occur off the coast of Indonesia, the waves can reach the coast in as little as twenty minutes -- leaving little to no warning time for residents in high-risk areas. The 2004 tsunami reached the province of Banda Aceh just a quarter of an hour after a magnitude-9.1 earthquake struck, resulting in 140,000 deaths in that region alone.

How Studying DNA From Ancient Animals Helps Humans

From Christian Science Monitor:

While on the campaign trail this fall, Senator John McCain would laugh at government-funded research on the DNA of bears. What would he think of the research on DNA from extinct cave bears that now has elucidated the bear family tree? It’s the latest example of how scientists are using the increasingly sharp cutting-edge of DNA research to clarify the divergence of animal species, including humans.

New techniques to rapidly analyze DNA accelerate such studies. An increasing ability to garner useful data from tiny samples of DNA enable scientists to make the most of what little DNA they extract from such ancient remains as cave-bear bones.

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.

From Science Daily:

ScienceDaily (Nov. 13, 2008) — What would happen in California was hit by the Big One? New 3-D animations of a magnitude 7.8 earthquake scenario are now available to the public.

Fourteen animations can be downloaded from the site in high definition format. The 3-D animations show, from the perspective of a several different Southern California locations, how intensely the ground would shake and shift during a very strong 7.8 earthquake with an epicenter on the southern end of the San Andreas Fault.

The science-based earthquake scenario, developed by USGS scientists and partners, is used for both the Great Southern California ShakeOut drill on November 13 and the statewide Golden Guardian 2008 emergency response exercise from November 13 - 18.

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.'

Obama Preparing Comprehensive Technology Policy

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.
