Biogen reports 6 new cases of PML with Tysabri

BOSTON (Reuters)– Biogen Idec Inc said six patients taking its multiple sclerosis drug Tysabri developed a potentially fatal brain infection in December, bringing the total number of such cases associated with the drug to 85.

The biotechnology company said that as of January 7, the overall incidence of progressive multifocal leukoecephalopathy, or PML, was 1.06 per 1,000 patients, up from 1.0 in 1,000 last year.

Biogen, which makes the drug with Irish drugmaker Elan Corp Plc, temporarily withdrew Tysabri from the market in 2005 after it was first associated with the condition; it was brought back, with stricter safety warnings, in 2006.

The drug is widely considered the most effective on the market, but its sales have been crimped by concerns over PML. The risk of the condition increases with the length of treatment.

After two years of monthly infusions, the incidence of PML is now 2.13 per 1,000 patients.

The overall rate of PML in clinical trials was 1 in 1000, a benchmark that has now been exceeded.

Of the 85 cases of PML reported, 16 patients have died, while 69 are still alive with varying degrees of disability.

Biogen is developing a test that it hopes will allow doctors to screen patients to identify which might be more likely to develop PML.

Biogen shares were down$2.02 or 2.9 percent to$66.76 in afternoon New York trading, while Elan shares were down 10 cents or 1.5 percent to$6.37.

SEC freezes assets in insider trading case

WASHINGTON (Reuters)– U.S. securities regulators said they froze bank accounts containing more than$800,000 in illegal profits after a manager at Seattle Genetics. gave his relative confidential information about drug trial results.

The Securities and Exchange Commission complaint, which was filed January 19 and unsealed on Friday, says that Seattle Genetics Manager Zizhong (James) Fan told his relative Zishen (Brandon) Fan about positive trial results in the development of a drug used to treat Hodgkin's lymphoma.

The SEC said Zishen spent hundreds of thousands of dollars buying speculative stock options and common stock in the company. The stock value rose 18 percent when the news about the drug trial was made public in late September, the SEC said.

The SEC said it contacted the men on January 13. Shortly afterward, it said Zishen tried to wire several hundred thousand dollars to a bank in China. Zizhong told Seattle Genetics he had to leave for a trip to China, the SEC said. The SEC did not say if he left the United States, and did not specify their family relationship.

Zizhong denied being related to or knowing Zishen, and Zishen denied knowing anyone at Seattle Genetics, the SEC said.

The SEC filed its complaint against both defendants in the U.S. District Court for the Western District of Washington and got an order from a judge freezing the bank and brokerage accounts that held the profits.

Calls to lawyers for Zizhong and Zishen were not immediately returned Friday.

Classified satellite launched from California base

VANDENBERG AIR FORCE BASE, Calif.– The largest rocket ever launched from the West Coast blasted off Thursday with a classified defense satellite on board.

The 235-foot-tall Delta IV Heavy Launch Vehicle lifted off at 1:10 p.m. carrying a payload for the National Reconnaissance Office.

The booster rose into the sky over California's central coast and arced over the Pacific Ocean, a spectacle visible over a wide area.

United Launch Alliance, the joint venture of rocket builders Lockheed Martin Corp. and Boeing Co., said in a statement that the launch was a success.

The launch was pushed back two minutes to avoid an object in space that could have been in the path of the rocket, said Michael J. Rein, a ULA spokesman.

No payload details were released. The NRO operates satellites that provide information to the Central Intelligence Agency and Department of Defense.

This was the fifth launch of a Delta IV but the first from the West Coast. The other four launches were at Cape Canaveral, Fla.

Capable of generating nearly 2 million pounds of thrust, the liquid-fuel rocket has a central core booster and two strap-on boosters that make the assembly 50 feet wide. An upper second stage takes over when the first stage is exhausted.

Preparing for the launch took three years and $100 million in infrastructure upgrades at Vandenberg, 130 miles northwest of Los Angeles.

The launch director, Lt. Col. Brady Hauboldt, said in a statement before the liftoff that the launch would mark a milestone by restoring heavy lift capability in the nation's western range. The last heavy lift Titan IV-B was launched at Vandenberg in 2005.

In its past, the launch complex was once configured for West Coast space shuttle launches, which were canceled after the 1986 Challenger disaster, and the Air Force's Manned Orbiting Laboratory program, which was canceled in 1969. It was last used in 2006.

After cutting value of life, EPA ditching the term

WASHINGTON– Bureaucrats are struggling with an age-old question: What is the value of our lives?

The government uses dollar amounts for lives when trying to weigh the costs and benefits of regulating such things as pollution, but it has proven politically and emotionally charged.

Now, the Environmental Protection Agency wants to stop putting a price tag on American lives and use different terminology, but that's not as easy as it sounds.

The agency's first try for a replacement— a wonky"value of mortality risk"— was shot down as not quite right by its science advisory board Thursday.

The EPA proposal would also put more value on preventing cancer deaths over other causes of death, like heart attacks. That's because there's a bigger scare factor for cancer, EPA officials said. But critics say that puts a premium on touchy-feely emotions over science.

"This is highly ethical, but very dangerous,"said David Ropeik, an expert in risk communications and author of the book"How Risky Is It, Really?"He said people often overestimate some risks, such as cancer, and underestimate others, such as heart disease.

For decades, the government in analyzing whether regulations make economic sense has used something called"value of a statistical life."

The so-called price tag became a political hot topic in 2002, when the Bush administration tried to reduce the value of elderly people by 38 percent compared to people under 70.

Then quietly in 2004, the EPA reduced the value of life for everyone from $7.9 million to $7 million. The Associated Press uncovered the devaluation in 2008 and the EPA's move was criticized by Democrats and ridiculed by comedians.

Soon after the Obama administration took over in 2009, the value of a statistical life was pushed back up to $7.9 million.

The EPA has proposed changing the term to"value of mortality risk"and instead of using dollars for a theoretical life, regulations would be measured in"dollars per micro-risk per year."A micro-risk is one in a million.

So instead of using the value of a life at $7.9 million when calculations are made about the benefits of a regulation, it would be using figures that talk about the benefits of reducing deaths by $7.90 per micro-risk per person per year.

Under the current EPA economic calculations, people are troubled by the question of"how do you put a value on a human life,"said Al McGartland, EPA's chief environmental economist.

With the new proposal,"we're not putting a value on a human life,"he said.

The new method is more understandable for the public, said Lisa Heinzerling, a Georgetown University law professor who until late last year was EPA's policy chief and the architect behind the change.

When environmental economists talked about value of life, they really were trying to figure out how much people would pay to reduce individual risk of death, so this is a more accurate term, said Heinzerling, co-author of a book called"Priceless: On Knowing the Price of Everything and the Value of Nothing."

But science board members said the proposed term is clunky and confusing. They suggested"value risk reduction."Eventually, the board will make a recommendation to EPA's chief, who will make the final decision.

No matter what term is used, the EPA's proposal"doesn't change anything, it still means the same thing. No one will be fooled for long,"Tufts University economist Frank Ackerman, co-author of Heinzerling's book, said in an e-mail.

The rebranding could bury key environmental decisions"in ever-deeper jargon,"said Frank O'Donnell, president of Clean Air Watch and a critic of the old method.

In the proposal, the EPA is adding a 50 percent"cancer differential"to calculating death risks. This would say the risk of dying of cancer is 50 percent worse— or costlier— than the risk of dying in other ways. EPA associate environmental economics chief Nathalie Simon pointed to scientific studies, based on surveys that say people would be willing to pay more to avoid dying of cancer, when compared to other causes of death.

John Graham, the Bush administration regulation chief who proposed discounting the value of seniors, said people may say they fear cancer more, but their actions don't back that up.

In an e-mail, Graham, now dean of Indiana University's school of public and environmental affairs, questioned whether a"cancer premium"can be justified"in light of the reluctance of citizens to monitor for radon in their homes, enroll in cancer screening programs, and eat their fruits and vegetables on a daily basis."

Swiss collector returns 4 ancient mummies to Chile

GENEVA– A Swiss collector has returned four pre-Columbian mummies to Chile, including two that are believed to be up to 7,000 years old.

The Swiss government says the unnamed collector agreed to voluntarily hand the mummies over to Chile. They were discovered near the country's northern Atacama desert.

Two of the mummies date back to the Chinchorro period that lasted from 5,000 to 1,500 B.C. This makes them older than the famed 3,300-year-old mummy of ancient Egyptian pharaoh Tutankhamun.

A third mummy belongs to an unspecified pre-Columbian period while the fourth dates to the time of the Spanish arrival in what is now Chile in the early to mid-1500s.

The preserved bodies were handed over to Chilean government officials Thursday at a small ceremony in Geneva.

Toshiba to build'huge solar plant'in Bulgaria

TOKYO (AFP)– Toshiba and Tokyo Electric Power will team up with the Japanese government to build one of the world's largest solar power stations in Bulgaria, according to a report.

The plant will be built in the eastern city of Yambol by March 2012 at a cost of more than 100 billion yen ($1.2 billion), Japan's Nikkei daily said.

As a European Union member, Bulgaria needs quickly to bolster its sources of renewable energy to reduce carbon dioxide emissions.

The EU has an aggressive goal to unilaterally cut carbon emissions by 20 percent by 2020, as compared to a benchmark year of 1990.

By tapping Japanese technology, the eastern European nation aims to pave the way for obtaining 16 percent of its power from renewable energy sources by 2020, up from roughly seven percent now, the report said.

Toshiba, Tokyo Electric, Japanese trader Itochu and the government-backed Innovation Network Corp. of Japan will set up a local joint venture, investing a total of around 50 billion yen.

CEZ Group, the seventh-ranked European power utility, will also take part in the joint venture, contributing as much as 20 billion yen, according to the report.

Japanese Economy and Industry Minister Banri Kaieda and Bulgarian Economy and Energy Minister Traycho Traykov will agree to support the consortium at a meeting early next week, the Nikkei said.

"It is true that Toshiba is carrying out various activities for developing solar power in Bulgaria," a Toshiba spokesman said."But we cannot comment on a specific project and nothing has been decided yet."

The plant will start with an output capacity of roughly 50,000 kilowatts. The capacity will gradually be increased to 250,000 kilowatts in five years, the business daily reported.

Midwest storm blamed for at least 6 traffic deaths

ST. LOUIS– A winter storm that blew across the Midwest on Thursday was blamed for at least six traffic deaths in the region, as it dumped more than a foot of snow in some parts and was expected to leave sub-zero temperatures in its wake.

The wintry weather also closed down schools and offices and sent plows and salt trucks working overtime to clear the roads.

In western Indiana, three people driving to a funeral were killed when their car collided with a semitrailer on a state road near the town of Waveland, about 50 miles west of Indianapolis, around 10 a.m. Montgomery County sheriff's Chief Deputy Ryan Needham identified the victims as 25-year-old Anthony Suggs of Ruskin, Fla., 21-year-old Logan R. Mills of Suwanee, Ga., and 25-year-old Amanda S. Mills of Buford, Ga.

Three people also died in Oklahoma in separate vehicle crashes early Thursday morning. Authorities said each of the three men appeared to have skidded off the icy roads while driving on highways in western and southern parts of the state.

The fatal accidents happened as the storm blanketed most of Oklahoma with 2 to 4 inches of snow.

Northeastern Kansas had up to 8 inches of snow on Thursday, and Missouri residents saw as much as 15 inches north of St. Louis.

National Weather Service meteorologist Jim Sieveking said the storm was concentrated on a narrow band over Interstate 70 in the central part of the state. Despite hundreds of trouble calls, including several overturned tractor-trailers, Missouri authorities reported no serious incidents.

"Virtually the entire state is covered in snow,"said Sally Oxenhandle of the Missouri Department of Transportation."We're working to try to get highways cleared as best we can."

As the storm front moved eastward Thursday, meteorologist said the upper Midwest would get an Arctic blast that would send temperatures plummeting to as low as minus-30 in northern Minnesota.

Things should warm up slightly by Saturday, but the weather service warned of another storm sweeping over the region Sunday night and Monday.

Northeast is waking up to snowy morning commute

NEW YORK– Snow in the Northeast is causing hazardous road conditions for the morning commute but has mostly tapered off south of New England.

There were no reports of problems at airports or on commuter trains, subways and buses Friday, but transportation officials are advising commuters to give themselves extra time.

In New England, forecasters say the storm is expected to dump 5 to 8 inches of snow. National Weather Service meteorologist Benjamin Sipprell says the quick-moving storm is not expected to affect power lines and tree limbs as did the wet, heavy snow the region endured a week ago.

The snow had stopped falling in New York City and New Jersey by about 8 a.m. The weather service says Central Park got about 4 inches of snow. Accumulations reached as much as 5 inches in northwest New Jersey.

Northeast storm to bring heavy snow

NEW YORK (Reuters)– A storm system moving up the East Coast is expected to bring areas of heavy snow and winds to New England on Friday, spreading into Maine late into the night.

Highs in the Northeast will be colder than average, ranging from the teens in the interior and northern New England to the 30s F along the coast from southern New England to Chesapeake Bay.

Snowfall in the north and east portions of the Plains hard red winter wheat region will help buoy soil moisture levels but dryness remains an overall concern in a large part of the western growing region.

Bitter cold temperatures may increase stress on the soft red winter crop in southern Illinois and northwest Ohio but no severe damage is expected.

Iceland may reverse Magma bid for HS Orka: Björk

OTTAWA (AFP)– Pop megastar Bjork told a Canadian newspaper Friday that Iceland's government is prepared to reverse Canada's Magma Energy Corp's takeover of geothermal energy producer HS Orka.

Bjork made the comments after last week presenting Iceland's prime minister and finance minister with a petition calling for a referendum on foreign ownership of the country's natural resources.

"They told us they want to reverse the (Magma) deal and make sure Iceland?s energy companies and the access to its energy stay in public property," Bjork told the daily National Post.

"They are serious," she added.

Magma said however that Bjork's comments were just"speculations and hearsay."

Bjork has since July headed a campaign to prevent the takeover of the Icelandic energy provider, announced in May, which has received regulatory approval in Iceland.

The petition welcomed by Iceland's Prime Minister Johanna Sigurdardottir was signed by nearly 50,000 people in a country with a population of just 320,000.

Bjork had held a three-day karaoke marathon in a bid to get more signatures for the petition, which is largely aimed at blocking the sale of Iceland's HS Orka energy group to Canadian company Magma Energy.

A committee appointed by the government to examine the deal, which would mark the largest foreign investment in Iceland since the country's economy all but collapsed in late 2008, has not yet presented its findings.

HS Orka produces about nine percent of Iceland?s electricity.

NASA's NanoSail-D Helps Promise Solar Sailing Ships

NanoSail-D, a small, solar sail,has unexpectedly ejected from the FASTSAT satellite, over a month after it was scheduled to. Now NASA is calling upon ham radio operators to confirm that NanoSail-D has deployed properly and is working.

NanoSail-D is about the size of a breadbox and massing 4.5 kilograms and the sails, if properly deployed on four extended booms, will be a hundred square feet. If successful, NanoSail-D will be the second vehicle to fly in space propelled by sunlight. The first, Ikaros, was launched by Japan in June, 2010.

Solar sails workby catching light particles from the sun on a reflective surface. Just like a regular sail boat propelled by the wind on Earth's oceans, a solar sailor would fly through the inner solar system propelled by the light of the sun. Beyond the orbit of Mars, a solar sailor would likely not be useful because of the dimness and distance of the sun.

Space visionaries imagine space craft, propelled by solar sails, voyaging, say, between Earth and Mars. The sails would be anywhere from the size of a football field to miles in diameter. Space ships with solar sails would be like the galleons or clippers of previous centuries, only flying the airless sea of space rather than the bounding ocean.

Ships with solar sails do not require rocket fuel and would accelerate constantly, slowly building up speed across great distances. They would decelerate the same way, shifting sails to use sunlight to slow down as they approached their destination. Solar Sailing ships could be used to move cargo to resupply Mars explorers, for example.

Solar sailing ships have been a stable of science fiction. Both Arthur C. Clarke and Poul Anderson wrote stories about solar sailing ships around the same time, ironically both entitled"Sunjammer." Solar sail ships were used in an episode of"Star Trek: Deep Space 9", in the film"Star Wars: The Attack of the Clones", in the James Cameron film"Avatar."

Some scientists envision solar sail ships being accelerated by a massive laser, sending it to hitherto unimaginable speeds to take it to the outer Solar System or even to other solar systems. Another idea for solar sailing star ships would be for the ship to accelerate while spiraling away from the Sun until it reaches solar escape velocity and then, when approaching the target star, decelerate in the same way.

Mark R. Whittington is the author of Children of Apollo and The Last Moonwalker. He has written on space subjects for a variety of periodicals, including The Houston Chronicle, The Washington Post, USA Today, the LA Times, and The Weekly Standard.

Giant crayfish found in Tennessee is new species

WASHINGTON (Reuters)– A new species of giant crayfish literally crawled out from under a rock in Tennessee, proving that large new species of animals can be found in highly populated and well-explored places, researchers said on Wednesday.

The new crayfish should not have been easily overlooked, as it is huge -- twice the size of other species, the team at the University of Illinois at Urbana-Champaign and Eastern Kentucky University said.

But the crustacean is also quite rare, they report in the Proceedings of the Biological Society of Washington.

"This isn't a crayfish that someone would have picked up and just said,'Oh, it's another crayfish,' and put it back," said University of Illinois aquatic biologist Chris Taylor, one of the researchers.

"You would have recognized it as something really, really different and you would have saved it," Taylor added in a statement.

Taylor and Guenter Schuster of Eastern Kentucky University found their first specimen of the new species under one of the biggest rocks in the deepest part of a commonly explored Tennessee creek.

The new species, called Barbicambarus simmonsi, is about 5 inches long and has antennae covered with a sensitive fringe of tiny, hair-like bristles, called setae.

More than half of the 600 known species of crayfish in the world are found in North America, Taylor said.

"This thing had not been seen by scientific eyes until last year," he said.

We spend millions of dollars every year on federal grants to send biologists to the Amazon, to Southeast Asia -- all over the world looking for and studying the biodiversity of those regions," Schuster said."But the irony is that there's very little money that is actually spent in our own country to do the same thing. And there are still lots of areas right here in the U.S. that need to be explored."

Feinberg discussing future pay for spill fund work

NEW ORLEANS– The administrator of the $20 billion compensation fund for Gulf oil spill victims and BP are discussing how much he will be paid for his services in the months ahead.

A spokeswoman for Ken Feinberg confirmed Tuesday the talks are happening. But she declined to say whether the Washington attorney is seeking a raise from the $850,000 a month his firm has been receiving.

That fee amount was valid through Saturday. Feinberg's contract with BP states that the two parties would discuss future fees on a quarterly basis. It also says that BP must approve any subcontractors Feinberg hires as part of the claims process.

A rig explosion last April off Louisiana killed 11 workers and led to 200 million gallons of oil being released from BP's well a mile beneath the Gulf of Mexico.

BP shares edge higher on news of Rosneft tie-up

LONDON (AFP)– Shares in British energy giant BP edged higher on Monday as investors gave a very cautious welcome to its Arctic tie-up with Russian state firm Rosneft.

BP's stock gained just 0.24 percent to finish at 500.70 pence on London's FTSE 100 index of top companies, having earlier risen to 512.10 pence, as the market gave its first verdict on the deal that was unveiled late Friday.

The FTSE, meanwhile, closed 0.27 percent lower at 5,985.70 points. US financial markets were closed for a public holiday.

BP chief executive Bob Dudley and Rosneft President Eduard Khudainatov flew into London on Friday to sign the agreement, which allows them to jointly exploit the vast untouched oil and gas resources of Russia's Arctic region.

The deal comes just nine months after the Gulf of Mexico oil spill disaster which ravaged BP's finances and its international reputation and it sparked considerable critical comment in the United States.

"There has been quite a backlash in the United States to the BP/Rosneft deal," noted GFT analyst David Morrison.

"But I think investors are harking back to the TNK(-BP) deal back in 2003. That went bad and Robert Dudley was forced to flee Russia as a result.

"Exploration in the region will be high-risk and expensive, and there is a concern that if anything goes wrong, BP could be left high and dry."

Rosneft will hold five percent of BP's ordinary voting shares in exchange for about 9.5 percent of Rosneft's stock. The shares issued by BP are worth approximately $7.8 billion (5.9 billion euros) and Rosneft's will be similar.

BP already owns half of Russia's third biggest oil producer, TNK-BP, where Dudley served as chief executive for five years until he was expelled by BP's Russian partners during a shareholder dispute in 2008.

"Given last year's rather undignified political rhetoric from some US political leaders (over the oil spill disaster), it is not altogether surprising that BP have sought to look elsewhere to bolster future revenue streams," CMC Markets analyst Michael Hewson said.

"However, the tie-up with Rosneft is certain to ruffle a few political feathers in the United States.

"Given the events of last year, US politicians have only themselves to blame as the oil company seeks to diversify its global exposure in order to better safeguard its future revenues."

In a separate development on Monday, Australia gave BP permission to explore for oil and gas off its south coast, saying the company had agreed to integrate lessons learned from the Gulf of Mexico spill in its operations.

Gunbattles, food shortages temper Tunisians' joy

TUNIS, Tunisia– Major gunbattles erupted outside the palace of Tunisia's deposed president, in the center of the capital, in front of the main opposition party headquarters and elsewhere on Sunday as authorities struggled to restore order and the world waited to see if the North African nation would continue its first steps away from autocratic rule.

Police arrested dozens of people, including the top presidential security chief, as tensions appeared to mount between Tunisians buoyant over Zine El Abidine Ben Ali's departure and loyalists in danger of losing major perks.

There were cheers and smiles in much of Tunis, the capital, as residents tore down the massive portraits of Ben Ali, some of them several stories high, that hung from lampposts and billboards and were omnipresent during his 23-year reign.

Prime Minister Mohamed Ghannouchi said on state TV that a new national unity government will"most certainly"be announced Monday"to open a new page in the history of Tunisia."

There are three legal opposition parties that could be included in the government Ghannouchi has been directed to form by the interim president, Fouad Mebazaa. Negotiations are advanced, Ghannouchi said Sunday night.

Worries among Tunisians, however, grew with the violence and worsening shortages of essentials such as milk, bread and fresh fish.

"We're starting to feel it now,"said Imed Jaound at the Tunis port, which has been closed since Friday, when Ben Ali fled to Saudi Arabia.

A gunbattle broke out around the presidential palace late Sunday afternoon in Carthage on the Mediterranean shore, about 15 kilometers (10 miles) north of Tunis. The army and members of the newly appointed presidential guard fought off attacks from militias loyal to Ben Ali, said a member of the new presidential guard. Helicopters were surveying the zone.

The militias emerged from a forest to charge, the guard member said by telephone. He told The Associated Press the militia are"numerous"and are using various kinds of arms but gave no further details. He spoke on condition of anonymity because he was not authorized to be publicly named.

Residents of Carthage— a center of power in ancient times but now a Tunis suburb popular with tourists— said they have barricaded themselves inside their homes amid the shooting. Many soldiers were in the palace, but it was unclear whether any of the interim government's leaders were.

One Carthage resident said she saw four men in a taxi speed through a military checkpoint at the end of her street and toward the palace nearby. Soldiers shot at the taxi and the men inside returned fire.

The resident, who asked not to be named because of security concerns, said her neighbors saw other armed men break through checkpoints in civilian cars. The gunbattle lasted about four hours before calm returned in the evening, she said.

Other gunfights broke out near the PDP opposition party headquarters and a two-hour-long gunbattle raged behind the Interior Ministry, long feared during Ben Ali's reign as a torture site. Residents of the city center heard constant volleys of gunfire throughout much of the afternoon; they were ordered to stay away from windows and keep their curtains closed.

The prime minister said Sunday night that police and the army have arrested numerous members of armed groups, without saying how many.

"The coming days will show who is behind them,"Ghannouchi said. He added that arms and documents have been seized from those arrested.

"We won't be tolerant towards these people,"the prime minister said.

The security chief, Ali Seriati, and his deputy were charged with a plot against state security, aggressive acts and for"provoking disorder, murder and pillaging,"the TAP state news agency reported.

Police stopped vehicles as the city remained under a state of emergency. More than 50 people were arrested on suspicion of using ambulances, rental cars and government vehicles for random shootings, a police official told The Associated Press. A crowd of 200 in Tunis cheered one such arrest Sunday.

Before the gunbattle at the opposition party headquarters, police arrested a group of nine Swedish boar hunters traveling in taxis toward a nearby hotel after their flight home was canceled, one of the Swedes, Ove Oberg, said. Police roughed the men up and accused them of being terrorists, Oberg said, recounting his ordeal before a group of journalists.

"When they saw this gun, they went crazy,"he said, referring to a hunting rifle in the trunk of the taxi.

Six of the men were released, some with their clothes stained with blood, while three others remained in police custody Sunday evening.

Dozens of people have died in a month of clashes that were initially between police and protesters angry about repression and corruption but now appear to be between police and Ben Ali loyalists.

A Paris-based photojournalist, Loucas Mebrouk von Zabiensky, 32, of the EPA photo agency, was in critical condition after being hit in the face Friday with a tear gas canister, according to a French consular official in Tunisia. The official, speaking on condition of anonymity because of embassy rules, did not provide other details or an explanation of an earlier announcement that the photographer had died.

Mebazaa, a former parliament speaker who was sworn in as interim president Sunday, has told Ghannouchi to create a national unity government and urged him to consult with the opposition, who were marginalized under Ben Ali. Presidential elections are to be held in 60 days.

The downfall of the 74-year-old Ben Ali, who had taken power in a bloodless coup in 1987, served as a warning to other autocratic leaders in the Arab world. His Mediterranean nation, a popular tourist destination known for its wide beaches, deserts and ancient ruins, had seemed more stable than many in the region before the uprising that began last month.

Hundreds of stranded tourists were still being evacuated from the country Sunday. The U.S. State Department issued a travel warning suggesting that U.S. citizens forgo travel to Tunisia and consider leaving if already there. It authorized the departure of nonessential U.S. Embassy personnel and of all family members of U.S. staff at government expense.

Tunisia's foreign minister will brief Arab leaders meeting in Egypt this week on the upheaval surrounding Ben Ali's ouster.

In Israel, Prime Minister Benjamin Netanyahu told his Cabinet that the unrest in Tunisia illustrated the widespread instability plaguing the region and underscored the need for strong security arrangements in any future peace deal with the Palestinians. Palestinians accused the Israeli leader of searching for excuses not to negotiate.

Many Tunisians were especially overjoyed at the prospect of life without Ben Ali's wife Leila Trabelsi and her family.

Leaked U.S. diplomatic cables released by WikiLeaks had discussed the high levels of nepotism and corruption displayed by Trabelsi's clan. But U.S. State Department spokesman P.J. Crowley rejected any notion that WikiLeaks disclosures led to the revolution in Tunisia, saying Sunday that Tunisians were already well aware of the graft, nepotism and lavish lifestyles of the former president and his relatives.

Tunisian media reported one brother-in-law of the president, Imed Trabelsi, was attacked by an angry mob at Tunis airport and died. The reports could not be immediately confirmed.

Ordinary Tunisians concentrated on two key needs Sunday— food and security.

Many scoured the capital for food as calm returned to some residential areas. Most shops remained closed Sunday, others were looted and bread and milk were running short.

Fish mongers were selling two- or three-day-old fish, said Ezzedine Gaesmi, a salesman at the indoor market in Tunis, where many stands were empty.

"There's no fresh fish. If it continues for two or three more days, we'll close,"he said.

Overnight citizen patrols armed with bats, sticks and golf clubs were being organized in both wealthy and working-class neighborhoods. Fatma Belaid stayed up late to serve rounds of coffee to patrols in her section of Tunis.

"Everyone participates as he can,"she said.

A well-known human rights advocate returned home to the embattled— but in many ways, hopeful— country. Souhayr Belhassen, president of the International Federation of Human Rights, said her long-repressed countrymen appear poised for unprecedented freedoms.

"We can start to hope,"agreed Nejib Chebbi, a founder of the opposition PDP party. But he said the key question is whether a new government will be pluralistic or again dominated by Ben Ali's RCD party.

"If the RCD is dominant, we're not out of the woods,"he said.

NASA Discusses Plan to Attach Bigelow Inflatable Module to ISS

NASA Space Flight is reportingthat a meeting took place at the Johnson Spaceflight Center to discuss the possibility of attaching a Bigelow inflatable module to the International Space Station.

The inflatable module would serve as a storage room for scientific equipment used in the Japanese Laboratory Module. NASA would provide funding, as well as equipment such as"--the Passive Common Berthing Mechanism (PCBM), Flight Releasable Grapple Fixture (FRGF), smoke detector, fan, and emergency lights." Bigelow would provide the inflatable and inner core structure.

Berthing the inflatable module at the ISS would require the addition of the currently unfunded Node 4 and the unfunded Advanced Rendezvous and Docking Vehicle. The module would be launched on an EELV, either a Delta IV or Atlas V.

If the Bigelow inflatable module is funded and deployed, it would constitute a curious full circle for NASA. NASA has originally studied using inflatable modules for the International Space Station under the Transhab program in the mid to late 1990s. The program was canceled, but Bigelow Aerospace bought the license for the technology, greatly refined it, and is now in the process of building its own private space station using inflatable modules, scheduled for sometime in the middle of this decade. Bigelow has successfully launched and deployed to inflatable prototypes.

Using a Bigelow inflatable module would be another example of the marrying of commercially developed technology to an important NASA project, much in the same way that NASA is promoting the development of commercial launch vehicles to resupply ISS. The difference is that Bigelow has developed its inflatable module technology under its own funding and will not need government subsidies to provide the product NASA is requesting.

If the funding is made available for the addition of a Bigelow module, the scheme promises to be a win/win situation for both NASA and Bigelow.

"Both NASA and Bigelow stand to gain from putting an inflatable module on the ISS. Given the fact that inflatable modules could play a major role in any future NASA interplanetary spacecraft or surface base, NASA could gain valuable in-flight data from an inflatable module on ISS, as well as much-needed stowage space.

"Bigelow would gain confidence in, and operational experience with, its inflatable modules in a crewed environment, confidence which would undoubtedly also be gained by any potential future customers to Bigelow. Given that the ISS is a permanently crewed operational environment, it is an ideal testbed to demonstrate these technologies."

This is very important as debates continue over how NASA is going to send astronaut/explorers beyond Low Earth Orbit. NASA plans envision commercial partnerships of various kinds. Bigelow, for instance, has suggested that with funding it could provide a ready-made lunar base with its inflatable modules ready to be occupied by people returning to the Moon. Such an arrangement would greatly enhance any program of lunar exploration and eventual settlement.

The question arises, of course, will the funding be made available? Considering the chaos that has descended upon NASA in the wake of the cancellation of the Constellation program and uncertainties about budgets, that is something that begs for an answer.

Obscure Full Moon Names of 2011

A bright full moon on a dark, clear night is always an impressive sight, but did you know that each full moon of the year has its own name? Sometimes, the full moon of each month even has more than one name, all of which originated in antiquity. 

Full moon names date back to Native Americans living in what is now the northern and eastern United States. Those tribes of a few hundred years ago kept track of the seasons by giving distinctive names to each recurring full moon. Their names were applied to the entire month in which each occurred.

There were some variations in thefull moon names, but in general the same ones were current throughout the Algonquin tribes from New England on west to Lake Superior. European settlers followed their own customs and created some of their own names. {Gallery: Our Changing Moon}

Since the lunar ("synodic") month is roughly 29.5 days in length on average, the dates of the full moon shift from year to year.

Here is a look at of the full moon names for 2011, as well as the dates and times for peak moon observing . Unless otherwise noted, all times are for the Eastern Time Zone:

Jan. 19, 4:21 p.m. EST– Full Wolf Moon:Amid the zero cold and deep snows of midwinter, the wolf packs howled hungrily outside Indian villages. The Full Wolf Moon was also known as the Old Moon or the Moon After Yule. In some tribes, this was also known as the Full Snow Moon; most applied that name to the next moon. 

Feb. 18, 3:36 a.m. EST– Full Snow Moon:Usually the heaviest snows fall in this month. Hunting becomes very difficult, and hence to some tribes this was known as the Full Hunger Moon. 

Mar. 19, 2:10 p.m. EDT– Full Worm Moon:In this month, the ground softens and the earthworm casts reappear, inviting the return of the robins. 

The more northern tribes knew this as the Full Crow Moon, when the cawing of crows signals the end of winter, or the Full Crust Moon because the snow cover becomes crusted from thawing by day and freezing at night. TheFull Sap Moon, marking the time of tapping maple trees, is another variation.

The moon will also arrive at perigee only 50 minutes later at 3:00 p.m. EDT at a distance of 221,565 miles (356,575 kilometers) from Earth. So this is thebiggest full moonof 2011. Very high ocean tides can be expected during the next two or three days, thanks to the coincidence of perigee with full moon. 

Apr. 17, 10:44 p.m. EDT– Full Pink Moon:The grass pink or wild ground phlox is one of the earliest widespread flowers of the spring. Other names were the Full Sprouting Grass Moon, the Egg Moon andamong coastal tribesthe Full Fish Moon, when the shad come upstream to spawn.

In 2011, this is also the Paschal Full Moon; the first full moon of the spring season. The first Sunday following the Paschal Moon is Easter Sunday, which indeed will be observed one week later on Sunday, April 24. This, incidentally, is just one day shy of the latest date that Easter can fall.

May 17, 7:09 a.m. EDT– Full Flower Moon:Flowers are now abundant everywhere. This moon was also known as the Full Corn Planting Moon or the Milk Moon.

Jun. 15, 4:14 p.m. EDT– Full Strawberry Moon:Strawberry picking season peaks during this month.  Europeans called this the Rose Moon. There will be also be atotal lunar eclipsethat will be visible across much of South America, Europe, Africa and Asia. Totality will last an unusually long length of time: 1 hour 40 minutes.

Jul. 15, 2:40 a.m. EDT– Full Buck Moon:when the new antlers of buck deer push out from their foreheads in coatings of velvety fur. It was also often called the Full Thunder Moon, thunderstorms being now most frequent. Sometimes it's also called the Full Hay Moon. 

Aug. 13, 2:57 p.m. EDT– Full Sturgeon Moon:When this large fish of the Great Lakes and other major bodies of water like Lake Champlain is most readily caught. A few tribes knew it as the Full Red Moon because when the moon rises it looks reddish through sultry haze, or the Green Corn Moon or Grain Moon.

The occurrence of this full moon on this particular date is rather poor timing for those who enjoy the annual performance of thePerseid meteor shower; this display will peak on this very same day and the brilliant light of the moon will likely wash out all but the very brightest of these swift streaks of light.

Sep. 12, 5:27 a.m. EDT– Full Harvest Moon:Traditionally, this designation goes to the full moon that occurs closest to the autumnal (fall) equinox. TheHarvest Moonusually comes in September in the Northern Hemisphere, but (on average) once or twice a decade it will fall in early October. 

At the peak of the harvest, farmers can work into the night by the light of this moon. Usually the moon rises an average of 50 minutes later each night, but for the few nights around the Harvest Moon, the moon seems to rise at nearly the same time each nightjust 25 to 30 minutes later across the U.S., and only 10 to 20 minutes later for much of Canada and Europe. Corn, pumpkins, squash, beans and wild ricethe chief Indian staplesare now ready for gathering.

Oct. 11, 10:06 p.m. EDT– Full Hunters' Moon:With the leaves falling and the deer fattened, it's now time to hunt. Since the fields have been reaped, hunters can ride over the stubble, and can more easily see the fox, as well as other animals, which can be caught for a Thanksgiving banquet after the harvest. 

Since the moon arrives at apogee about 10 hours later, this will also be thesmallestfull moon of 2011.  In terms of apparent size, it will appear 12.3 percent smaller than the full moon of Mar.19.

Nov. 10, 3:16 p.m. EST– Full Beaver Moon:At this point of the year, it's time to set beaver traps before the swamps freeze to ensure a supply of warm winter furs. Another interpretation suggests that the name Full Beaver Moon come from the fact that the beavers are now active in their preparation for winter.  It's also called the Frosty Moon.

Dec. 10, 9:36 a.m. EST– Full Cold Moon:On occasion, this moon was also called the Moon Before Yule. December is also the month the winter cold fastens its grip.

Sometimes this moon is referred to as the Full Long Nights Moon, and the term"Long Night" Moon is a very appropriate name because the nights are now indeed long and the moon is above the horizon a long time. This particular full moon makes its highest arc across the sky because it's diametrically opposite to the low sun.

Last, but certainly not least, this will also be the night of a total lunar eclipse.Viewers across the western United States and Western Canada can catch the total phase before the moon sets. Alaska and Hawaii can see the entire event from start to finish. Central and Eastern Asia and Australia are also well placed for viewing this eclipse (where the calendar date will read Dec. 11). Totality lasts 51 minutes.

Japanese carmakers in push for hydrogen vehicles

TOKYO (AFP)– Japan's top three automakers Toyota, Honda and Nissan have united with Japanese energy firms in a push to commercialise greener hydrogen fuel cell cars and build a network of fuelling stations.

Along with 10 Japanese energy groups including natural gas refiners and distributors, the companies are aiming to build 100 filling stations by 2015 in Tokyo, Nagoya, Osaka and Fukuoka, the companies said in a statement Thursday.

The automakers are making a renewed push behind Fuel Cell Vehicles (FCVs), which covert hydrogen into electricity and emit nothing more harmful than water vapour.

The companies say that the creation of a hydrogen supply infrastructure network is crucial as manufacturers work to reduce the production cost of hydrogen-powered vehicles in order to make them commercially viable.

"Japanese automakers are continuing to drastically reduce the cost of manufacturing such systems and are aiming to launch FCVs in the Japanese market -- mainly in the country's four major metropolitan areas -- in 2015," they said.

"With an aim to significantly reduce the amount of CO2 emitted by the transportation sector, automakers and hydrogen fuel suppliers will work together to expand the introduction of FCVs and develop the hydrogen supply network throughout Japan."

The companies did not say how much they planned to invest in the project.

While all-electric vehicles such as Nissan's Leaf or hybrids like Toyota's Prius have hogged the limelight recently, fuel cells are seen as a more powerful alternative, but expensive production and a lack of a comprehensive fuelling network has been seen as prohibitive.

Toyota, pioneer of hybrids powered by a petrol engine and an electric motor, has said it plans to launch a fuel-cell car by 2015. It is applying its hybrid technology to the vehicles, swapping the petrol engine for a fuel-cell stack.

Honda in 2008 began delivering about 200 FCX Clarity hydrogen-powered cars on lease to customers in the United States, Japan and later in Europe.

2010 ties 2005 for warmest year on record: US

WASHINGTON (AFP)– Last year tied with 2005 as the warmest year on record for global surface temperature, US government scientists said in a report on Wednesday that offered the latest data on climate change.

The Earth in 2010 experienced temperatures higher than the 20th century average for the 34th year in a row, the National Oceanic and Atmospheric Administration said.

Overall, 2010 and 2005 were 1.12 degrees Fahrenheit (0.62 Celsius) above the 20th century average when taking a combination of land and water surface temperatures across the world, it said.

Those two years were also the highest in temperature since record-keeping began in 1880.

"If the warming trend continues, as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long," said James Hansen, the director of NASA's Goddard Institute for Space Studies (GISS).

Last year was the wettest on record, NOAA said citing Global Historical Climatology Network which made the calculation based on global average precipitation, even though regional patterns varied widely.

When it came to hurricanes and storms, the Pacific Ocean saw the fewest number of hurricanes and named storms, three and seven respectively, since the 1960s.

But the Atlantic Ocean told a different story, with 12 hurricanes and 19 named storms, which include tropical storms and depressions, marking the second highest number of hurricanes on record and third highest for storms.

The analysis also tracked weather changes that contributed to massive floods in Pakistan and a heat wave in Russia, saying an"unusually strong jet stream" from June to August was to blame.

"The jet stream remained locked in place for weeks, bringing an unprecedented two-month heat wave to Russia and contributing to devastating floods in Pakistan at the end of July," it said.

Expert Bob Ward at the Grantham Research Institute on Climate Change and the Environment at London School of Economics and Political Science said the US data shows proof of climate change.

"These new figures show unequivocally that the Earth is warming and its temperature is at record levels," Ward said.

Last year's data"also showed that the amount of carbon dioxide in the atmosphere had reached 390 parts per million, its highest level for at least 800,000 years and almost 40 per cent higher than the level before the start of the Industrial Revolution when humans started to burn fossil fuels in increasing amounts," he said.

"The evidence is overwhelming that human activities are driving climate change."

In the United States alone, 2010 marked the 14th year in a row with higher annual average temperatures when compared to the long term average since 1895, NOAA said.

Record snowfalls at the start of the year in the northeast including Washington and Philadelphia were part of a winter pattern driven by El Nino and the Arctic Oscillation, NOAA said.

A separate report by Canada's Environment Ministry said that last year was the warmest in Canada since it began keeping meteorological records 63 years ago.

NASA analysts said the shrinking sea ice in the Arctic may have made winters in Europe and Canada warmer than usual.

"Winter weather patterns are notoriously chaotic, and the GISS analysis finds seven of the last 10 European winters warmer than the average from 1951 to 1980," NASA said in a statement.

"The unusual cold in the past two winters has caused scientists to begin to speculate about a potential connection to sea ice changes," it said.

"Arctic sea ice acts like a blanket, insulating the atmosphere from the ocean's heat. Take away that blanket, and the heat can escape into the atmosphere, increasing local surface temperatures. Regions in northeast Canada were more than 18 degrees (F) warmer than normal in December.

Ohio ex-NASA worker charged over military exports

CLEVELAND– The Department of Justice says a former NASA employee in Ohio has been charged with illegally shipping infrared military technology to South Korea.

Sixty-six-year-old Kue Sang Chun of Avon Lake was charged Monday with one count of exporting defense articles on the U.S. munitions list without getting an export license or written authorization from the federal government.

Authorities say Chun exported infrared focal-plane array detectors and infrared camera engines.

They say Chun is a former employee at the NASA Glenn Research Center but is not accused of taking technology from the center.

He's also charged with making a false individual income tax return.

Chun's attorney said his client is cooperating with authorities.

What Does It Take to Survive a Bullet to the Brain?

Doctors at Arizona University Medical Center are"cautiouslyoptimistic" about Representative Gabrielle Giffords' recovery from thegunshot that struck her on Saturday.

Rep. Giffords (D-Ariz.) was shot in the left side of her head, wasresponsive to voice commands after the shooting and was in the operatingroom within 38 minutes, according to a statement from the MedicalCenter.

A person's chances of surviving such a trauma to the brain depend onthe areas of the brain that are struck, the velocity of the bullet andwhether the bullet exits the brain, said Dr. Keith Black, chairman ofneurosurgery at Cedars-Sinai Medical Center in Los Angeles.

If a bullet passes through both the right and left hemispheres of thebrain, instead of being confined to one side, as it was in the case ofRep. Giffords, then the damage is likely to be much worse, Black said.

"Thebrain is somewhat redundant- it can sometimes tolerate losing one half," Black said. Like atwin-engine plane that has lost one engine, he said, a person whosebrain was pierced by a bullet on only one side has a better chance thansomeone who has suffered injury to both sides.

It's also a positive sign if the bullet misses the brain's"high-value real estate," such as the brain stem and the thalamus, Blacksaid. These deepbrain structuresare crucial to consciousness and basic functions such as controllingbreathing and the heartbeat. And a person has a better chance ofrecovering if the bullet misses the major blood vessels that bringoxygen to areas where it's needed.

The left side of the brain, where Giffords was struck, controlslanguage and speech, so the fact that Giffords was responding to thosespeaking to her after her injuryshows that she may be able to understand and process language - a very good sign for her recovery, Black said.

A bullet that misses the brain's ventricles - the cavities within thecenter of the brain that are filled with cerebrospinal fluid - alsoleaves a person in better shape than one that strikes these regions. Ifstruck, the cavities may fill with blood, which may lead tocomplications such as hydrocephalus (a swelling of the brain), which canfurther endanger the victim.

The speed of the bullet as it travels through the brain makes a difference as well.

"A high-velocity bullet does more damage than a low-velocity bullet,"Black said. High-speed bullets, such as those fired by an AK-47 orother military weapon, do more peripheral damage to theregions of the brainaround their path as they pass through than slower-moving bullets, such as those fired by handguns.

And,"if it stays in the brain, it does more damage," Black said,than a bullet that exits the brain, as it did in Rep. Giffords' case.

A shooting victim stands a better chance if they don't stop breathingand if their blood pressure remains high enough - both functions areneeded to maintain an adequate oxygen supply to the brain. Arriving at aLevel 1 trauma center - the highest level and most prepared to providecare for such injuries - shortly after such a trauma can help maintainor sometimes restore these functions, Black said.

The medical team treating Giffords removed part of her skull, andBlack said this allows the brain to swell without becoming compressed.

"Inside the skull, the brain is like jello in a jar," Black toldMyHealthNewsDaily."If it doesn't have any place to expand, there can beeven more damage. Confinement can prevent blood flow."

Later, when the swelling subsides, the part of the skull that wasremoved is replaced, he said. Swelling often peaks on the third dayafter such an injury, but in Rep. Giffords' case, doctors may wait aslong as several months to replace the bone, he said.

"With a gunshot wound, they may be worried that the bullet brought inbacteria. They may want to make sure there's no evidence of infectionbefore they replace the skull," Black said.

Q&A: The'Snowman'Talks Wild Winter Weather

When snow hits the ground, New Jersey's state climatologistgets calls from the morning news shows about the best packing snow conditionsand snowman fashion accessories. But David Robinson also runs an internationalsnow-cover database that includes satellite data from the past five decades.

That data on snow cover comes from the National Oceanic andAtmospheric Administration (NOAA), butRobinson cleans up the data and updates a map so that people cancomparepresent snowfallwith that of past years. Such information, hosted byRutgers University in New Jersey, endedup in the executive summary of the most recent report by the IntergovernmentalPanel on Climate Change.

LiveScience caught up with Robinson while reporting from thefall meeting of the American Geophysical Union in December to talk about all thingssnow-related.

Q: Thanks fortaking the time to talk.

A: You know, I'vedone thewhiteChristmas storiesbefore. I've actually done two interviews over my yearsas a snow scientist, although both may have come at me - I'm the stateclimatologist in New Jersey - and they may have just come from reporters on howto build a snowman.

They call,"Oh, what's the best snow, and what do yousay to do this?" I've gotten such a kick out of those,"Well, NewJersey can have good snow because it's not real powdery and it's often wetenough." One time I talked to a fashion person about how to decorate thesnowman after it was built, so I had to help them construct it ... the point isyou have to have fun with this sometimes.

Q: Right.Speaking of snow, what about all thosestrange snowfall eventswe hear about?

A: You can findsnow in some odd places at somewhat unusual times of the year, and it's afortuitous alignment of cold and moisture. It doesn't signify the coming iceage, nor is it indicative of global warming. In the short term, while it's an extreme,and climate change is likely to lead to more extremes, you know as well as I dothat one extreme doesn't cut it.

Then there's always the fact with all of these {events} thatthey may have happened before, and not all that far into the past. In this CNNworld, things get reported quickly. That biases the reporting record {towardthe present}. It snows in Miami, you're going to get tweets and blogs andeverybody's going to know. So you have to filter that these days.

Q: Does that meanwe shouldn't be surprised by these unusual weather patterns?

Interestingly enough, in the first half of November, thesnow cover in the western half of Eurasia was well below average. I wasstarting to think we were headed toward satellite record period lows, and thenthe last two weeks of the month, just ... bam! And North America was low untilmid-November, and then it just exploded. If you wait around long enough ... Ialways say the difference is that meteorologists get the instant feedback. Climatologistshave to be patient. And you can't jump to conclusions on the 15th of the monthand say,"Oh, we're going to have a record for the month," because assoon as you say that, it flips around.

Now somebody was telling me ... Phil Jones, poor Phil Jonesfrom East Anglia who made all the news {aboutClimategate}.Phil and I were talking this morning, and he said that some spot in England hadthe warmest day on record in November, last month, and the coldest day onrecord last month.

But that's the beauty of the climate system. When it getsinto a hyperactive state you go to extremes, you go from warmth to cold. Asopposed to ... you get these periods of zonal flow, where the cold stays where itbelongs and the warmth stays where it belongs. But if you get that jet streamin what we call meridional pattern - big buckles - and you can go from oneextreme {to another}. {A meridional pattern is an atmospheric system that flowsalong a meridian, or a large imaginary circle on Earth's surface that crossesboth poles.}

Syracuse {in New York} had about 66 inches of snow thismonth {December} so far. The first day of December they were 63 degrees F withtwo inches of rain. They just had an amazing month. On TV this morning, theytried to point out that it's half their winter snow and it's not even winteryet! Well, climatologically, it's winter. Syracuse gets impacted by lake-effectsnows, and lake-effect snows are most prominent when the lakes are still warmearly in the season, so it's not unusual to front-end load Syracuse's snow.

Q: Have therebeen any changes in snowfall or snow cover over the past years?

A: I've looked attrends in extent of snow cover. Fall and winter over the 45-year satelliterecord don't show a trend in snow cover (that's snow on the ground, notsnowfall). But the spring{s} of each decade, the 70s, 80s, 90s, the past decade,have had decreasing amounts of spring snow cover. In other words, fall snowsaren't coming later from what we've seen in the record in recent decades, butsnows are melting earlier starting in mid- to late winter and working their wayup.

Even last winter, North America had record extensive snowcover in February. Skeptics were out there saying,"Ooh, climate changeisn't so bad." I said,"Wait until spring." Spring had the leastamount of snow cover on record. We went from the most amount of snow to theleast amount of snow cover. For reasons yet to be fully understood ... we'restill working on whether the snow packs are thinner going into the spring,whether we're bringing warm air up into the snow-covered regions earlier, or whetherthe background is warm enough and primed, because all you need to get is to thefreezing point.

That's the neat thing about snow. It's not this linear thing- it's all about the freezing point. We had an incredibly mild winter last yearin the higher latitudes, but it was still plenty cold enough to have snow. Itwas just a little cooler in the mid-latitudes, and that was just enough to makeit snow.

Q: Have youenjoyed keeping the climate records and tracking snow cover?

A: It's beenwonderful. It's something I latched onto, and I've not been a day without sometype of research support since I was a grad student to look at it. Right now,when you go onto our website, you can find the daily product NOAA created. Butwe actually took the long-term weeklies and made a daily climatology.

So now when you go onto this website, you not only see wherethe snow is today, but I believe we're the only place in the world where youcan hit the next button and see where it's anomalously low, or how extensive orbelow average. Because you look at the map and think,"Oh well, that'sinteresting," but then you think,"Should there be snow or shouldn'tthere be snow?" I hardly ever look at the map, I go right to the anomalymap. I'm real pleased and proud of that one. So it's been fun. Like I said, yougot to have some fun with this. It's serious stuff - this is a key climateindicator, it integrates temperature, precipitation, weather patterns andextremes - but everybody loves to talk about snow.

GOP bills would curb EPA on global warming battle

WASHINGTON– House Republicans wasted no time Thursday in trying to block the Obama administration from acting to stem global warming. On their second day in power, GOP lawmakers introduced several bills that would hamstring the Environmental Protection Agency from moving forward with regulations to reduce heat-trapping pollution from factories and other sources that they say contributes to global warming.

The bills are part of an effort by House Republicans to reverse what they consider job-killing policies of the administration. The bills introduced by Rep. Ted Poe of Texas, Rep. Marsha Blackburn of Tennessee and Rep. Shelley Moore Capito of West Virginia would stymie the EPA in different ways.

Poe's measure would prohibit the EPA from using any money to implement or enforce regulations to impose a limit on global warming gases. Blackburn's bill would change the Clean Air Act so the EPA could no longer use the law to control greenhouse gases.

A 2007 Supreme Court decision said the EPA had the authority to regulate carbon dioxide and other global warming gases under the statute.

Capito's measure would delay for two years any effort by the EPA to regulate carbon dioxide under the Clean Air Act.

In a statement, Capito called the EPA's actions a power grab that would have devastating effects on the economy.

"Without congressional action to say otherwise, the EPA will continue to dismantle energy and manufacturing industries through regulation,"she said.

Meanwhile, a top Democrat in the Senate on environmental issues, Sen. Barbara Boxer of California, said Thursday she would use every tool to block the Republicans efforts and ensure that the EPA was allowed to follow the law.

A bill that would have placed a limit on heat-trapping gases died in the Senate last year, after it passed the then Democratic-led House. Boxer said there are no plans to pursue another one because there are not enough votes.

UK lawmakers: No need to stop deepwater drilling

LONDON– A major oil spill at a deepwater well in the North Sea would be more difficult to handle than the Gulf of Mexico disaster, but a moratorium on drilling isn't necessary because Britain has tougher safety standards, a committee of lawmakers said Thursday.

Legislators also stressed that a ban on drilling would leave Britain too reliant on imported energy as they backed the government's decision not to impose a moratorium.

After hearing weeks of testimony on the U.S. spill from regulators and oil executives, including BP's former CEO Tony Hayward, Energy and Climate Change Committee chairman Tim Yeo said his panel was satisfied Britain has a tougher safety regime than that in place in the gulf at the time of the Apr. 20 explosion.

However, the panel criticized the energy industry for complacency in preparing for unlikely, but potentially catastrophic events, and urged Britain's government not to rely on"controversial conclusions"in BP's internal report as it seeks to draw lessons from the spill.

Environmental groups including Greenpeace had urged Britain's government to suspend deepwater extraction until the full implications were understood of the explosion at the BP-operated Deepwater Horizon platform on April 20 that killed 11 people and sparked the biggest oil spill in U.S. history.

Yeo said his committee had concluded that a moratorium"would undermine the U.K.'s energy security and isn't necessary."

Britain tightened regulation in the North Sea after the country's worst offshore accident, a 1988 explosion on the Occidental Oil-owned North Sea Piper Alpha rig that killed 167 workers. Since April, the U.K. government has increased the number of rig inspectors in the North Sea, where there are 24 drilling rigs and 280 oil and gas installations.

The panel said any spill in the North Sea would pose more serious difficulties than those encountered in the Gulf. The remote location means there are only a limited supply of rigs that could be deployed to drill relief wells, while lower sea surface temperatures means the process of natural evaporation would be slower than in the U.S. incident.

"There are serious doubts about the ability of oil spill response equipment to function in the harsh environment of the open Atlantic in the West of Shetland,"the committee's report said.

In his testimony in September, Hayward— who has since been replaced by Bob Dudley— told legislators that deepwater extraction would continue to be necessary to meet current energy demands. He also said BP was not solely to blame for the Gulf disaster.

Though pressed on BP's safety record, there was no repeat in Britain of the onslaught of criticism Hayward endured when he appeared before the U.S. House Energy and Commerce Committee in June.

Robert Smith, a lawmaker from government coalition partner the Liberal Democrats and a member of the British committee, said the panel accepted that any restrictions on North Sea deepwater drilling would undermine the country's energy independence."If there was a moratorium, it would stop new development of gas supplies at a time when we are seeing concerns about winter reserves. It is important not to overreact,"he told The Associated Press.

Ministers argue that Britain must exploit its domestic oil and gas reserves— particularly until the country is able to produce more energy from renewable sources.

"Oil and gas are set to remain a key part of our energy system for years to come and it is vital that we search for and produce the U.K.'s own resources as safely as possible,"Energy minister Charles Hendry said in a statement.

The government estimates there are still around 20 billion barrels of oil equivalent to be discovered and produced from British waters in the North Sea. But overall oil production is expected to drop to around 1 million barrels per day within five years, from 1.36 million barrels per day in the 2009/10 financial year.

The committee's report also called on regulators to consider whether additional safety measures are required on deep water rigs.

"Requiring oil rigs to fit an extra fail-safe device, to cut and seal the pipes if a blowout occurs, is an option that must now be considered,"Yeo said.

Lawmakers warned that current legislation could lead to confusion over who would pick up the bill following any major U.K. spill.

Energy companies presently have their liability limited to $250 million per incident, which lawmakers said is too little. It is also unclear whether they would need to pay compensation for damage to wildlife and habitats.

Smog Contributes to Dangerous Heart Rhythm Disorders

TUESDAY, Jan. 4 (HealthDay News) -- The role that air pollution plays in heart rhythm disorders (arrhythmias) that can cause sudden death may be underestimated, according to researchers.

A small study of 25 healthy people without heart disease found detectable changes in the heart's electrical system when the participants were exposed to polluted air.

The findings suggest that air pollution may interfere with the heart's ability to reset its electrical properties in an orderly manner, said the researchers. This can lead to arrhythmias, which can cause sudden cardiac death in some people.

The fact that air pollution can have this effect on healthy people indicates that people with heart disease may be at even greater risk from air pollution than previously believed, the study authors said.

They called for more research into the link between air pollution and arrhythmias, along with greater physician awareness and participation in efforts to increase public knowledge about the danger and to reduce air pollution.

The study appears in the Jan. 11 issue of theJournal of the American College of Cardiology.

US lets some companies resume Gulf drilling

WASHINGTON (AFP)– Thirteen oil companies have been authorized to resume deepwater drilling in the Gulf of Mexico without submitting new plans for environmental review, the US Department of the Interior said.

But the companies will still have to comply with tougher safety rules on offshore drilling that were put in place last year to try to avoid a repeat of the April 2010 accident on a BP rig, which killed 11 workers and sparked a massive oil spill, the Interior Department said.

Companies that were already drilling in the Gulf when a deepwater moratorium was imposed may be allowed to resume their activities without submitting new exploration or development plans for scrutiny.

"We are taking into account the special circumstances of those companies whose operations were interrupted by the moratorium and ensuring that they are able to resume previously approved activities," Michael Bromwich, director of the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) said.

"For those companies that were in the midst of operations at the time of the deepwater suspensions, today?s notification is a significant step toward resuming their permitted activity," he said.

The BOEMRE is the Interior Department agency responsible for overseeing the safe and environmentally responsible development of offshore energy and mineral resources on the US outer continental shelf.

The 13 companies the BOEMRE notified are ATP Oil and Gas, BHP Billiton Petroleum, Chevron USA, Cobalt International Energy, ENI US, Hess, Kerr-McGee Oil and Gas, Marathon Oil, Murphy - USA, Noble Energy, Shell Offshore, Statoil, and Walter Oil and Gas.

The ban on deepwater drilling was lifted in October, five months after it had been imposed to allow the Interior Department and an expert panel commissioned by President Barack Obama to craft new safety rules for offshore drilling.

US, UK scientists draw up list of world's plants

LONDON– British and U.S. scientists say they've compiled the most comprehensive list of land plant species ever published— a 300,000-species strong compendium that they hope will boost conservation, trade and medicine.

The list, drawn up by researchers at Kew Gardens in London and the Missouri Botanical Garden in St. Louis, is intended to help resolve one of botany's most basic problems: Figuring out which plants go by what name.

Some plants have been labeled differently by researchers operating in different countries over the past century, while in other cases the different variants of the same plant have been erroneously identified as belonging to different species. There are also cases in which plants names' have been applied mistakenly, or just misspelled.

Although a rose by any other name may still smell as sweet, scientists say that attaching different labels to the same plant can rob researchers of the chance to get the information they need.

"If you only know it by one of its many names you only get part of the story,"said Eimear Nic Lughadha, the senior scientist at Kew responsible for the list.

It's a problem that frustrates everyone from agricultural regulators to pharmaceutical researchers.

"Imagine trying to find everything that's ever been published about a plant: Which chemicals are in it, whether it's poisonous or not, where is it found,"said Alan Paton, one of Nic Lughadha's colleagues at the Royal Botanic Gardens at Kew."To find that information, you need to know all of the different scientific names that have been used for it."

The plant compendium aims to clear up that confusion by putting all the various names in one place— and sorting out which ones apply to which plant. To that end researchers in the U.S. and Britain have been scooping up existing databases— with names such as GrassBase and iPlants— and combining them with checklists from organizations such as the World Checklist of Selected Plant Families and The International Legume Database and Information Service.

Kew's final list carries more than 1 million scientific names, of which 300,000 are accepted names for plant species. Another 480,000 are additional names, or synonyms, for those species. The rest are unresolved— they could apply to a previously identified plant, or they could describe a different organism altogether.

Botanists are still working their way through the backlog of unassigned names.

"Finishing that list will be a long task,"Nic Lughadha said."And, of course, new species are being described all the time."

Japan agency warned not to accept whale meat gifts

TOKYO– The Japanese fisheries agency has warned its officials against accepting whale meat as gifts from whalers, just weeks after Japan's whaling expedition left for the Antarctic Ocean for its annual hunts.

The agency reprimanded five officials for accepting whale meat from a fisheries company that operates the government-funded whaling programs from 1999 to 2008, agency official Koji Hamada said Friday.

The whale meat gifts totaled some 25 kilograms (55 pounds), worth more than 270,000 yen ($3,260) at market value, he said.

The officials were suspected of violating public servants' ethical standards. They acknowledged accepting the gifts after returning from each whaling expedition they accompanied separately as a supervisor. The punishment was announced Wednesday.

Earlier this month, Japanese whalers left for the Antarctic Ocean for their annual hunts, and the Sea Shepherd Conservation Society boats have also left New Zealand in pursuit.

Clashes between the whalers and opponents have escalated in recent years, and a Sea Shepherd boat sunk after a collision with a whaling ship last January. Each hunting season runs from about December through February.

The agency's investigation followed media allegations last year that whalers and officials were siphoning off meat from the tax-funded whaling programs, Hamada said. Two Greenpeace activists in 2008 stole a package containing whale meat, claiming it was proof of wrongdoing.

A Japanese court in September convicted them of trespassing and theft, ordering suspended prison terms while acknowledging murky gift-giving practices among whaling officials.

Hamada said whaling operators Kyodo Senpaku Kaisha and the Institute of Cetacean Research have been asked to stop sending whale meat gifts to officials. He denied the punishment had anything to do with the ruling.

"The point is, whether it is whale meat or not, we should not accept any gifts that invite suspicion from the public,"he said.

Japan hunts whales under the research exemption to a 1986 worldwide ban on commercial hunts. Critics say there is no reason to kill the animals, and that the research program amounts to commercial whaling in disguise because surplus meat from the hunt is sold domestically.
