Alleged Cop-Killer Has Calif. Region on Edge

Police officers across Southern California are on the defensive and scaling back their public exposure today, no longer responding to "barking-dog calls" and donning tactical gear outside police stations as former-cop-turned-alleged-gunman Christopher Dorner, armed and apparently on the hunt for cops, remains at large.

Dorner is suspected of killing one cop and two civilians during a rampage that began Sunday, injuring two other officers along the way.

Police departments have stationed officers in tactical gear outside police departments, stopped answering low-level calls and pulled motorcycle patrols off the road in order to protect officers who might be a target of Dorner's alleged rampage.

"The person we suspect of doing this is mobile, and with California's interstate highway system, every hour that goes by that's another 60 or 70 or 80 miles or greater circumference, it is a very wide net," Chief of Police Sergio Diaz of the Riverside police department said.

"We've made certain modifications of our deployments, our deviations today and I want to leave it at that, and also to our responses. We are concentrating on calls for service that are of a high priority, threats to public safety, we're not going to go on barking dog calls today," Diaz said.

Sgt. Rudy Lopez of the Los Angeles police department said Dorner is "believed to be armed and extremely dangerous."

Police have also put Dorner's license plate number and car description on highway signs, although they warn Dorner might have changed his license plate.

A former Los Angeles police officer and Navy reservist, Dorner released an online manifesto before the shooting saying that he was targeting law enforcement and would be hard to capture because of his knowledge of police tactics.

The Los Angeles police department has sent dozens of patrols to guard specific targets named in Dorner's manifesto, which cops say he posted online.

Dorner wrote a long letter posted to his Facebook page in which he explained that he had been wrongly fired from the Los Angeles police department and would take revenge on those that wronged him.

The fired California cop went to a yacht club near San Diego overnight where police say he attempted to steal a boat and flee to Mexico.

He aborted the attempted theft when the boat's propeller became entangled in a rope, law enforcement officials said. It was at that point he is believed to have headed to Riverside, where he allegedly shot two police officers.

"He pointed a handgun at the victim [at the yacht club] and demanded the boat," Lt. David Rohowits of the San Diego Police Department said.

Police say the rifle marksman shot at four officers in two incidents overnight, hitting three of them: one in Corona, Calif., and the two in Riverside, Calif.

Lopez said two LAPD officers were in Corona on special detail to check on one of the individuals named in Dorner's manifesto and encountered Dorner. Dorner allegedly grazed one of them but missed the other.

"[This is an] extremely tense situation," Lopez said. "We call this a manhunt. We approach it cautiously because of the propensity of what has already happened."

After Dorner allegedly shot at LAPD officers in Corona, he fled and encountered two Riverside police officers stopped at a red light in their police car. Dorner used a rifle to shoot through their windshield, killing one officer and injuring the other.

The deceased officer was a 34-year-old, 11-year veteran of the police department. The injured officer, age 27, is expected to make a full recovery.

Diaz said that the names of the officers are being withheld to protect their families, who might be targeted by Dorner if the names are released.

"They were on routine patrol stopped at a stop light when they were ambushed," Lt. Guy Toussant of the Riverside police department said.

In the manifesto Dorner published online, he threatened at least 12 people by name, along with their families.

"Your lack of ethics and conspiring to wrong a just individual are over. Suppressing the truth will leave to deadly consequences for you and your family," Dorner wrote in his manifesto.

A badge and identification belonging to Dorner have been found in San Diego, according to San Diego police Sgt. Ray Battrick. Dorner's LAPD badge and ID were found by someone near the city's airport, and turned in to police overnight, The Associated Press reported.

Los Angeles Police Department Chief Charlie Beck said today that 40 protective details have been deployed to protect officers and their families.

"We are taking all measures possible to ensure safety of our officers and their families," he said.

Dorner is also believed to be responsible for the weekend slayings of an assistant women's college basketball coach and her fiancé in what cops believe are acts of revenge against the LAPD, as suggested in his online manifesto.

Lawrence was found slumped behind the wheel of his white Kia in the parking lot of their upscale apartment complex in Irvine Sunday and Quan was in the passenger seat.

"A particular interest at this point in the investigation is a multi-page manifesto in which the suspect has implicated himself in the slayings," Maggard said.

Police said Dorner's manifesto included threats against members of the LAPD. Police say they are taking extra measures to ensure the safety of officers and their families.

The document, allegedly posted on an Internet message board this week, apparently blames Quan's father, retired LAPD Capt. Randy Quan, for his firing from the department.

One passage from the manifesto reads, "I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty."

"I never had the opportunity to have a family of my own," it reads. "I'm terminating yours."

Dorner was with the department from 2005 until 2008, when he was fired for making false statements.

Randy Quan, who became a lawyer in retirement, represented Dorner in front of the Board of Rights, a tribunal that ruled against Dorner at the time of his dismissal, LAPD Capt. William Hayes told The Associated Press Wednesday night.

According to documents from a court of appeals hearing in October 2011, Dorner was fired from the LAPD after he made a complaint against his field-training officer, saying in the course of an arrest she had kicked a suspect who was a schizophrenic with severe dementia.

After an investigation, Dorner was fired for making false statements.

Euro slips ahead of ECB meeting

NEW YORK: The euro slipped against the US dollar on Wednesday ahead of the European Central Bank's policy meeting, expected to keep monetary policy on hold.

Meanwhile, the Japanese currency pulled higher after hitting three-year lows on Tuesday.

The euro fell to $1.3519 at 2200 GMT, from $1.3582 late Tuesday, nearly two cents below its 14-month high of $1.3710 hit on Friday.

The slip came a day before ECB policymakers were to meet, with most analysts saying they will not undertake any more easing of monetary conditions despite worries about slow growth and the strengthening euro.

On Tuesday French President Francois Hollande urged a more managed euro, saying it should not be allowed to "fluctuate depending on the markets' mood."

"A single currency zone must have a foreign exchange policy, otherwise it will see an exchange rate imposed on it (by the markets) which is out of line with its real competitive position," he told the European parliament.

Also weighing on the euro was concerns about political instability in Spain, where the government is under attack over corruption allegations, and Italy, where former prime minister Silvio Berlusconi, much distrusted by markets and Europe's technocrats, was gaining in election polls.

"There is enough uncertainty around Spanish and Italian politics to ensure that the next leg higher for the euro is delayed," said Kit Juckes of Societe Generale.

Hollande's plea came amid increased worries from around the world over a global currency war.

A key target of those worries, the Japanese yen, pulled higher on Wednesday a day after hitting three-year lows.

The yen sagged further on Tuesday following the announcement by Bank of Japan chief Masaaki Shirakawa that he would step down three weeks before his term ends, after butting heads with the new Japanese Prime Minister Shinzo Abe over monetary policy.

Abe wants the central bank to undertake more easing to reinflate the slumping economy.

But the yen edged higher Wednesday, with a dollar buying 93.57 yen, compared with 93.61 yen a day earlier.

The euro slipped to 126.46 yen from 127.13 yen.

The British pound was virtually unchanged at $1.5658; the dollar rose to 0.9101 Swiss francs from 0.9077 francs.

Rajnath Singh will contest again from Ghaziabad Lok Sabha seat

GHAZIABAD: Quelling speculations over its choice of candidate for the Ghaziabad Lok Sabha seat, the BJP in a meeting on Wednesday clarified that party president and sitting MP Rajnath Singh will contest the 2014 general elections from the constituency. The announcement has been made in the light of recent conjectures by rival political parties - particularly after Singh was elevated to the post of party president - that BJP would field a fresh candidate from Ghaziabad.

Singh, a former chief minister of Uttar Pradesh, had been elected to the Lok Sabha from Ghaziabad in the 2009 general elections after defeating his nearest rival, the Congress candidate Surendra Prakash Goel, by a margin of over 90,000 votes.

The BJP unit in Ghaziabad informed that ever since Singh was elected national president in January, rival political parties had launched systematic campaigns against him, fabricating theories that he would no longer contest from Ghaziabad.

"These rumours have been floated to wean away his vote base from the region. Opponents have developed cold feet over the prospect of Singh playing a major role at the centre if BJP forms the government after the general elections," said SP Singh, BJP (Mahanagar), Ghaziabad. "That's why Singh's name has been sealed for Ghaziabad well ahead of formally declaring the list for Uttar Pradesh," he added.

The BJP said chances of Singh moving out from Ghaziabad are even more remote because the party is looking ahead to increase its tally in western UP, including re-gaining the parliamentary seat of Gautam Budh Nagar, which had remained in the party's kitty continuously from 1991 to 2009. In 2009, BSP candidate Surendra Nagar had trounced BJP's Dr Mahesh Sharma to win the Gautam Budh Nagar seat.

Though BJP functionaries remained tight-lipped about the choice of their candidate for Gautam Budh Nagar, party sources informed that Rajnath's son, Pankaj Singh, is being considered to make his electoral debut from this seat.

As per sources, Pankaj Singh might be fielded in Gautam Buddh Nagar to consolidate on the overwhelming Thakur vote bank in the constituency.

"Besides, the party is also trying to cash in on the youth appeal of Pankaj Singh in Noida and Greater Noida," said a senior BJP member.

Confirmed: Couch Potatoes Have Lower Sperm Counts

Men, here's another reason to work up a sweat: It boosts your sperm count.

According to new research, couch potatoes who watch lots of TV have fewer sperm than men who exercise moderately or vigorously each week.

Sperm count is a measure of semen quality, which has mysteriously declined in U.S. men in recent decades. Low sperm count is linked to infertility as well as testicular cancer, prostate cancer, and cardiovascular problems later in life.

(Related: "Deep-Voiced Men Have Lower Sperm Counts, Study Says.")

That's why scientists have been searching for ways that men can improve their sperm—including changing daily behaviors.

"We know little about how lifestyle may impact semen quality," said study leader Audrey Jane Gaskins, a doctoral student in nutrition at the Harvard School of Public Health.

Her discovery that two changeable behaviors—exercise and TV watching—"could have a big impact on sperm count is pretty exciting," she said.

"Impressive" Sperm Finds

For the study, Gaskins and colleagues asked 189 young men, mostly college students from the University of Rochester in New York, to fill out questionnaires on their physical activity, diet, stress, and other lifestyle factors.

Each man then provided a semen sample in a medical clinic. (See "Sperm Recognize 'Brothers,' Team Up for Speed.")

The results showed that the men who reported exercising more than 15 hours a week had 73 percent higher sperm counts than men who exercised fewer than 5 hours a week. And men who watched more than 20 hours of TV had 44 percent lower sperm counts than men who watched little to no TV.

These are "pretty impressive differences," said Gaskins, whose study appeared February 4 in the British Journal of Sports Medicine.

The team also ruled out smoking and being overweight—two clinical causes of low sperm counts—as contributing factors among participants in its study.

Why couch potatoes produce less sperm is unknown, although there are two theories, Gaskins said. One is that exercise produces more antioxidant enzymes that can prevent a natural process called oxidative stress from damaging cell membranes in the body. This damage can disrupt the creation of new sperm cells. (Find out how a man produces 1,500 sperm a second.)

The other reason is somewhat controversial: That when men watch TV, their scrotums get squished against their bodies, making that region hotter and possibly preventing new sperm from being made.

Some research has shown that sperm production slows if the scrotum temperature rises 1.8 to 3.6ºF (1 to 2ºC) above normal body temperature, Gaskins said. But other studies have also shown that warmer scrotums have no bearing on sperm creation.

Get Moving, Men

But the study also raises some more questions about sperm count, experts noted.

Oddly, the sedentary subjects' sperm didn't show any changes in their physical structures or in how well they swam—two soft indicators of sperm health, noted Phillip Mucksavage, a urologist at Pennsylvania Hospital in Philadelphia who was not involved in the study. (See "Sperm Tracked in 3-D-A First.")

Though there are fewer of them, "the sperm that are there still look good."

Mucksavage added that the study's results would have been stronger if the scientists had found other sedentary activities—such as sitting at a computer or reading a book—had the same affect on sperm count as did watching TV.

What's more, said T. Mike Hsieh, a urologist at the University of California, San Diego, the study doesn't have any implications for fertility, one of the main reasons men are concerned about sperm count.

That's because one semen sample is not enough to determine fertility. That requires a more thorough analysis, including multiple semen samples and blood work, said Hsieh, who wasn't involved in the study.

It's not like if you "stop watching TV you'd go from infertile to fertile," he said.

But all the experts agreed on one thing: you should get active if you aren't already.

Said Hsieh: "I would use this as a piece of evidence to motivate my patients to get off the couch and start working out."

Galaxy May Be Full of 'Second Earths'

You may look out on a starry night and get a lonely feeling, but astronomers now say our Milky Way galaxy may be thick with planets much like Earth -- perhaps 4.5 billion of them, according to the Harvard-Smithsonian Center for Astrophysics.

Astronomers looked at data from NASA's Kepler space telescope in orbit, and conclude that 6 percent of the red dwarf stars in the Milky Way probably have Earth-like, habitable planets. That's a lot by space standards, and since red dwarfs are very common -- they make up three out of four stars in our part of the galaxy -- we may have a lot more neighbors than we thought.

The nearest of them, astronomers said today, could be 13 light-years away -- not exactly commuting distance, since a light-year is six trillion miles, but a lot closer than most yellow stars like Earth's sun.

Video: Are We Alone? Kepler's Mission

David A. Aguilar/Harvard-Smithsonian Center for Astrophysics

"We thought we would have to search vast distances to find an Earth-like planet. Now we realize another Earth is probably in our own backyard, waiting to be spotted," said Courtney Dressing, an astronomer at the Harvard-Smithsonian Center, in announcing the findings today. The results will be published in The Astrophysical Journal.

David Charbonneau, a co-author, said, "We now know the rate of occurrence of habitable planets around the most common stars in our galaxy. That rate implies that it will be significantly easier to search for life beyond the solar system than we previously thought."

Red dwarfs are older, smaller and dimmer than our sun, but a planet orbiting close to one could be sufficiently warmed to have liquid water. Dressing and her colleagues cited three possible planets that were spotted by Kepler, which was launched in 2009. One is 90 percent as large as Earth, and orbits its red sun in just 20 of our days.

There is no saying what such a world would actually be like; the Kepler probe can only show whether distant stars have objects periodically passing in front of them. But based on that, scientists can do some math and estimate the mass and orbit of these possible planets. So far, Kepler has spotted more than 2,700 of them in the small patch of sky it has been watching.

There are estimated to be 200 to 400 billion stars in the Milky Way -- which is probably a pretty average galaxy. So the new estimate implies a universe with tremendous numbers of Earth-like planets, far beyond our ability to count.

Pictures: Final Frontier: Images From the Distant Universe

Could they be friendly to life? There's no way to know yet, but space scientists say that if you have the right ingredients -- a planet the right size, temperatures that allow for liquid water, organic molecules and so forth -- and the chances may be good, even on a planet that is very different from ours.

"You don't need an Earth clone to have life," said Dressing.

Strengthening security at the nation’s airports

Most people think of airport security as their walk through the metal detector and the eyeballing by transportation security officers (TSOs). Dan Liddell, whose job it is to protect the flying public at seven airports in central New York, instead sees 17 zones of worker responsibility and hundreds of different tasks.

In pursuit of safeguarding the public, Liddell, a federal security director based in Syracuse, has written a book that is now used to train TSOs. It’s called the “National Standardization Guide to Improving Security Effectiveness.” Tasks at each duty area have been inventoried and cataloged, and the “knowledge, values and skills” associated with the airport security jobs have been identified under what Liddell describes as a systems approach to training.

As important as it is to use X-ray machines and explosive trace-detection equipment and to have the correct rules and procedures in place, Liddell said transportation security relies on the skills of the people responsible for it.

“People performance is the cornerstone,” he said. “When I set out to improve things, I look at the people. I look at their proficiency, their skill in doing something and how well they’re doing that job.”

Even when people have the skills to do their jobs, they don’t necessarily do them well each time, especially when conditions can vary with each day and every passenger. To keep performance high, TSOs are tested covertly at unexpected times. A banned item will be sent through a checkpoint and the reaction and activities that take place are monitored.

Whether or not TSOs spot contraband, everyone at that checkpoint during the test participates in an “after-action” review. “It’s the learning experience that’s relevant,” Liddell said. “We’re doing a review of actual performance and you can always improve.”

Liddell is sensitive to the pressure that airport security personnel face. TSOs have the tough of performing multiple tasks under constant camera surveillance and public scrutiny, often interacting with tired or irritated travelers. The testing and training helps them continually up their game.

Thirty airports around the country that helped test the training system and now use a version of it. Paul Armes, federal security director at Nashville International Airport, was interested in creating such a system with a colleague when they both worked in Arizona, but it “never got traction.”

When he learned about what Liddell was doing, he was eager to participate. “Typical of Dan, he built it himself and practiced it so he had hard metric results, and then he started reaching out to some of us, working with his counterparts around the country to get a good representative sample,” Armes said. “He sees things others don’t see sometimes and he has the capability to drill down into the details.”

Liddell began the “pretty long process” of analyzing how people were performing at checkpoints in 2009. He sat down with subject-matter experts to produce the task inventory he now uses. In 2010, he improved the review and reporting process that occurs after covert tests events and instituted the security practices he refined at the other New York airports he oversees, including Greater Binghamton, Ithaca and four others. “I love breaking it down,” he said. “I’ve got a quest for improvement.”

In a less sneaky version of the television show, “Undercover Boss,” Liddell went through the new-hire training program for his employees to understand as much as he could about the jobs and the training provided for them, he said.

If pursuing knowledge is in Liddell’s genes, it may be because his parents were both in education. His father was a high school principal and his mother was a fifth-grade teacher. His teaching manifested itself instead in the training realm, where he strives to educate security employees as effectively as possible, inside the classroom and out.

“It’s always a challenge to meet that right balance of really great effectiveness and really great efficiency,” he said. “There are always challenges. It’s what gets me up in the morning, trying to improve.”

Dell unveils private equity buyout worth US$24.4b

NEW YORK: Dell unveiled plans to go private Tuesday in a $24.4 billion deal giving founder Michael Dell a chance to reshape the former number one PC maker away from the spotlight of Wall Street.

"I believe this transaction will open an exciting new chapter for Dell, our customers and team members," Michael Dell said in unveiling the deal with equity investment firm Silver Lake, and backed by a $2 billion loan from Microsoft.

The company said it had signed "a definitive" agreement to give shareholders $13.65 per share in cash -- a premium of 25 percent over Dell's closing share price on January 11, before reports of the deal circulated.

The move, which would delist the company from stock markets, could ease some pressure on Dell, which is cash-rich but has seen profits slump, as it tries to reduce dependence on the slumping market for personal computers.

The plan is subject to several conditions, including a vote of unaffiliated stockholders.

It calls for a "go shop" period to allow shareholders to seek a better offer.

The company founder said Dell has made progress in its turnaround strategy "but we recognize that it will still take more time, investment and patience, and I believe our efforts will be better supported by partnering with Silver Lake in our shared vision."

"I am committed to this journey and I have put a substantial amount of my own capital at risk together with Silver Lake," he added.

Under terms of the deal, Michael Dell, who currently owns some 14 percent of Dell's common shares, would remain chairman and chief executive and boost his stake with "a substantial additional cash investment," a company statement said.

Additional cash for the deal will come from Silver Lake, a major tech investment group, and MSD Capital, a fund created to manage Michael Dell's investments.

The plan also calls for a $2 billion loan from Microsoft, rollover of existing debt, and financing committed by Bank of America-Merrill Lynch, Barclays, Credit Suisse and RBC Capital Markets.

Analysts have said the deal may give the company a chance to regain some footing in a market in which smartphones and tablets are overtaking laptop and desktop computers.

"Michael has been trying to turn Dell into a supplier of enterprise solutions for a long time," said Roger Kay, analyst with Endpoint Technologies.

"He has pleaded with Wall Street to give him time."

Kay told AFP that going private would make a transition easier by avoiding the spotlight of "ugly results," which could come from scaling back the PC business.

"The commodity PC business has been suffering," Kay said.

"Dell may probably keep the higher margin consumer lines, but maybe look at rest of the portfolio."

Kay added that Microsoft's participation in the deal suggests that Dell would remain in PCs and the Windows-based ecosystem.

Deutsche Bank's Chris Whitmore in a research note this week that Dell "would be free to execute his turnaround without the scrutiny of the public market" with "flexibility to do what he sees fit in order to drive long-term value."

The analyst added that Dell "could get more aggressive" in its enterprise software and cloud services, to make the company less dependent on PCs.

The Texas-based computer maker, which Dell started in his college dormitory room, once topped a market capitalization of $100 billion as the world's biggest PC producer.

Dell is now the number three global PC maker, behind Hewlett-Packard and Lenovo, according to the latest report from market tracker IDC, showing Dell's market share of 10.6 percent in the fourth quarter.

Rival HP said in a statement that Dell "has a very tough road ahead" with "an extended period of uncertainty and transition that will not be good for its customers," adding that HP "plans to take full advantage of that opportunity."

Microsoft's participation further clouds the role of the Windows software maker, which has begun its own hardware efforts with the Surface tablet.

Microsoft said in a statement it "is committed to the long-term success of the entire PC ecosystem and invests heavily in a variety of ways to build that ecosystem for the future."

Rain, snow continues to disrupt life across northern Himalayan region

DEHRADUN/SHIMLA/SRINAGAR: Rescuers were on Tuesday rushed to rescue around 300 pilgrims and tourists stranded en route to Gangotri and Yamnotri in Uttarakhand due to the closure of roads following heavy snowfall across the region.

"We have sent teams to shift these stranded pilgrims and tourists to safer places and hope to rescue them speedily,'' an official said.

Elsewhere in the state, uninterrupted rain and snowfall triggered massive landslides and paralyzed normal life in Garhwal and Kumaon divisions. Reports said the landslides forced closure of 280-km Rishikesh-Gangotri road along with Rishikesh-Badrinath and Kedarnath yatra routes.

In Uttarkashi, the plunge in the mercury forced authorities to close schools for two days. Authorities in Pauri, Chamoli, Tehri and Pithoragarh are likely to follow suit.

Day temperatures dropped by 8 to 10 degrees in places likes Dehradun, Haridwar and Haldwani.

Dehradun Met director Anand Sahrma told TOI that more rain and snowfall was expected for next two days. ``We have sounded an alert urging people to move carefully especially while driving or trekking in hills due to possibility of more landslides.''

Normal life remained disrupted in Himachal Pradesh, where remote areas remained cut off from the outside world due to heavy snowfall. Intermittent rains and sleet along with icy winds lashed the state's lower reaches.

Authorities have sounded an avalanche threat in high altitude areas and advised people to stay indoors.

Manali experienced 60cm and was cut off while the Rohtang Pass recorded 150cm snow.

In Jammu & Kashmir, the lifeline Jammu-Srinagar National Highway remained closed for the third day due to heavy snowfall and landslides. Over 400 vehicles and hundreds of passengers were stranded along the only surface route connecting the Valley with the outside world due to heavy snowfall and landslides.

Life Found Deep Under Antarctic Ice For First Time?

For the first time, scientists believe they have collected life-forms from deep under the Antarctic ice.

Last week, a team found and collected microbes in a lake hidden under more than a half-mile of ice. (Related: "Race Is On to Find Life Under Antarctic Ice.")

Among other things, the discovery may shed light on what lies under the icy moons of Jupiter and Saturn.

The newfound life-forms have little connection to life on the earth's surface and many apparently survive by "eating rocks," team member Brent Christner said in an interview from the U.S. McMurdo Station, after spending several weeks working at a remote field site at Lake Whillans.

That may explain how life on other celestial objects—such as on the moons of Jupiter and Saturn—survive in the absence of carbon.

"The conditions faced by organisms in Lake Whillans are quite parallel to what we think it would be like on those icy moons," Christner said.

"What we found tells us a lot about extreme life on Earth, and also how similar life might make a living beyond Earth."

Making a Living in Ice

A 50-member U.S. team broke through to the 20-square-mile (50-square-kilometer) subglacial lake on January 28, and had two days of 24-hour sunlight to bring up samples before the borehole began to close. A day of reaming the hole was followed by two more days of sample collection.

The scientists are now returning with a four-day haul of lake water, lake bottom sediments, and hundreds of dishes of living organisms that are being cultured for intensive study in the United States.

An early task will be to make sure the newfound microbes were not introduced while drilling through the ice into the lake, which involved a hot-water drilling technique designed to greatly reduce or eliminate any contamination that might come from other kerosene-based drilling technology, Christner said.

Christner said that a commonly used dye was added to the water to illuminate the DNA of the microscopic organisms, and a substantial green glow told scientists that microbes were indeed present. Many of the organisms are likely chemolithotrophs, which rely on inorganic compounds of iron, sulfur, and other elements for nourishment.

Montana State's John Priscu, chief biologist of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) program, said lab work at the drill site determined that microbial cells were present—and that they were alive. (Take an Antarctic quiz.)

"I believe it is safe to say that subglacial lake beneath the Whillans Ice Stream supports a microbial assemblage that is growing within this dark and cold habitat" of 31 degrees Fahrenheit (-0.5 Celsius), he wrote in an email.

DNA sequencing in the U.S. "will tell us who they are and, together with other experiments, tell us how they make a living."

Hidden Lakes

The U.S. team is one of three digging into what is now known to be a vast system of lakes and streams deep below the surface of Antarctica. (See "Chain of Cascading Lakes Discovered Under Antarctica.")

A British team attempting to drill into much deeper Lake Ellsworth had to return home in December because of equipment failure, but a Russian team is also at work now retrieving a core of water from Lake Vostok.

With much fanfare, the Lake Vostok core was pulled up last year from more than 2.5 miles (4 kilometers) below the frigid surface. Vostok is much deeper and larger than any other Antarctic lake, and both it and Ellsworth lie under much colder ice and are believed to have less deep subsurface water flowing in and out than does Whillans.

The existence of subglacial lakes and streams in Antarctica is a relatively new discovery, and the size of this wet world under the ice has only been grasped in recent years. (See Antarctic pictures by National Geographic readers.)

Helen Fricker, a glaciologist at the Scripps Institution of Oceanography and a principal investigator of the Whillans team, first described Lake Whillans in 2007.

Using satellite data, she and her colleagues discovered a periodic rising and falling of the ice surface above the Whillans Ice Stream between 2003 and 2006, and concluded that a lake was likely underneath.

The dynamics of Antarctic ice has taken on a much greater significance in the era of global warming, since some 90 percent of Earth's fresh water sits on the continent.

Although the lakes themselves are not affected by warming, how they interact with the region's ice is important to predicting the future behavior of the ice sheets.

For instance, understanding whether the ice is moving more quickly toward the surrounding ocean is a key goal of the WISSARD project, which is part of a larger U.S. National Science Foundation project to understand the ice movements, glaciers, and biology of the ice sheet of West Antarctica.

More Work to Be Done

For Christner, a specialist in Antarctic biology at Louisiana State University, the work has only just begun. (Also see "Pictures: 'Extreme' Antarctic Science Revealed.")

Two labs were brought to the Whillans site by a caravan of trucks from McMurdo: One to perform a quick analysis of the lake water, and the other to examine sediment.

Christner's team is charged with culturing samples in dishes so they can be studied more extensively later. He said some of the microbe species, including bacteria and archaea, may be unique, but many may well be found elsewhere—at great ocean depths and deep underground.

Sierra's Family Selling Photos to Cover Funeral, Kids

The family of Sarai Sierra, an amateur New York photographer slain while on a trip to Turkey, put her photos up for sale today and quickly sold enough photographs to pay forher funeral, the woman's brother said today.

The photos remain on sale and the profits will now be going to her two young sons, the family said.

Sierra, 33, was found bludgeoned to death near a highway in Istanbul on Saturday. Her iPhone and iPad, the tools she used to share her photos with her thousands of Instagram followers were reportedly missing.

The Staten Island mother of two traveled to Turkey alone on Jan. 7 after a friend had to cancel. It was Sierra's first overseas trip, and she kept in contact with her family the entire time, they said, sharing stories of her journey and posting photos online.

"Sarai's passion for photography and love for capturing the beauty we see in culture, architecture and scenery was her reason for traveling to Istanbul," her brother, David Jimenez, wrote on a website set up to sell his sister's photography.

Among the photos for sale are Istanbul sunsets, and shots of Sierra's beloved New York City.

By this afternoon, Jimenez put out another message saying, "Hey Instacanvas, Thank you for all the support in purchasing Sarai's pictures. Quick update, all expenses for Sarai's funeral have been paid for! From here on out any picture of hers that you purchase will NOT be going towards her funeral. All funds will be going to her children. Thank you for your support. David"

Sierra had been scheduled to arrive home at Newark Liberty International Airport on Jan. 22. When her husband, Steven Sierra, called the airline, he was told his wife never boarded the flight from Istanbul.

Steven Sierra and Jimenez traveled to Istanbul to aid in the search.

An intense two week search for for Sarai Sierra ended when her battered body was found.

An autopsy was completed Sunday, but results aren't expected for three months. Turkish officials however said Sierra was killed by at least one fatal blow to her head.

A casket holding the Staten Island mother was taken to a Istanbul church Monday where it remains as Sierra's family makes arrangements to bring her home.

Turkish police hope DNA samples from 21 people being questioned in the case will be key to finding the perpetrators, state media reported. A motive is not yet clear.

"They're still investigating so they might think it might be a robbery, but they're not sure," said Betsy Jimenez, Sierra's mother, said Monday.

The family also faces the heartbreaking task of telling Sierra's two sons, ages 11 and 9, that their mother is dead.

The boys have been under the impression that their father has gone to Turkey to bring their mother home - alive.

"It's going to be the hardest thing he's ever going to have to do in his life," said Rep. Michael Grimm, (R-NY) who added that the Staten Island family isn't sure when Steven Sierra will be able to bring his wife's body home.
