Leopards and humans peacefully coexist in India

By Becky Oskin, LiveScience

Leopards and humans peacefully share the same densely populated rural landscape in western India, a new camera trap survey shows.?

The cameras caught leopards and other jungle cats, as well as hyenas and jackals, prowling close to houses through the night in farmland in western Maharashtra, India. The carnivores and people shared the same paths ? so much so that the researchers had to turn off their camera traps during the day because of the human and livestock traffic.?

Yet the leopards went largely undetected by people, according to a statement from the Wildlife Conservation Society (WCS), which helped fund the study.?

"Human attacks by leopards were rare despite a potentially volatile situation considering that the leopard has been involved in serious conflict, including human deaths in adjoining areas," Ullas Karanth of the WCS, a study co-author, said in the statement. "The results of our work push the frontiers of our understanding of the adaptability of both humans and wildlife to each other's presence."?

The findings were published online March 6 in the journal PLOS One.?

The camera traps documented 10 large carnivores per 38 square miles (100 square kilometers) in the densely populated area ? five leopards and five hyenas. The human population density is more than 300 people per 38 square miles.

The discovery of so many large carnivores living in proximity to people highlights the need to focus on conservation outside of protected areas, the researchers said.?

The farming-intensive landscape lacks wilderness and wild herbivores for prey, and the region has only one protected area for wildlife, the Kalsubai Harishchandragarh Wildlife Sanctuary, the researchers said.?

Southampton beats Chelsea 2-1 in Premier League

Associated Press Sports

updated 2:02 p.m. ET March 30, 2013

SOUTHAMPTON, England (AP) -Rickie Lambert scored for the 14th time in his first Premier League season as Southampton beat Chelsea 2-1 on Saturday to edge closer to securing its status in the top flight.

The highest scoring Englishman in the league this season struck from a free kick in the 35th minute only two minutes after Chelsea captain John Terry had cancelled out Jay Rodriguez's 23rd-minute opening goal at St. Mary's Stadium.

After also beating Liverpool last round, Southampton rose two spots to 13th, four points above the relegation zone with seven matches left.

The result endangers Chelsea's bid to finish in the top four and qualify for the Champions League. The reigning European champions are only two points ahead of fifth-place Arsenal after their first league loss in five weeks.

Health Consumers Don't Give Back Online

People consulting the Internet for health information and advice take what's presented, but rarely give back by posting their own reviews or experiences, new research finds.

This pattern could be skewing the "wisdom of the crowds" about doctors, hospitals and treatment options, said study researcher Rosemary Thackeray of Brigham Young University.

"If more people are contributing to the dialogue, we have maybe better information," Thackeray told LiveScience. "Versus with fewer people, it might be less reliable, more biased."

An estimated 60 percent of people go online looking for health information, and social media is a part of that picture. Social sites include not just the big names like Facebook and Twitter, Thackeray said, but forums, discussion boards and health-specific sites such as PatientsLikeMe. [Read More: Health Insurance Reviews]

Thackeray and her colleagues analyzed data from the 2010 Health Tracking Survey, part of the Pew Internet & American Life Project. As part of the telephone survey, 1,745 adults who said they look up health information online answered questions about the sort of information they sought and posted.

The results revealed that 41 percent consulted consumer reviews of doctors, hospitals and treatments, and 32 percent used social media as part of their research. But only 10 percent posted health-care reviews of their own, and 15 percent posted comments, questions or information in response to others' queries.

"People were consuming information a lot more than they were actually contributing to the dialogue," Thackeray said.

Women were more likely than men to go online looking for health information, which is not surprising, as women tend to be the health-care decision makers in families, Thackeray said. Higher-income people, younger individuals and urban or suburban dwellers were also more likely than poorer, older and rural groups to go online. People with a regular health-care provider and health insurance were also more likely to seek health information online, probably because they have more health-care choices, Thackeray said.

"Some of those demographics mirror who is actually using social media anyway, so you're not finding a lot of older people posting online or consulting online even though they have more health conditions," she said.

Finally, people with chronic diseases were twice as likely as those without to seek health information online. The findings appear online in the Journal of Medical Internet Research.

Inaccurate and biased information is always a concern online, Thackeray said, but there are advantages to seeking out social media input about health ? and reasons to encourage more people to contribute.

"Take what you find online from family and friends, combine that with what you know from your health-care provider," she said. "Together, with all that information, you can become a more informed health-care consumer and make the best decisions for your health."

Rematch! It's Kirk vs. Gorn in this 'Star Trek' game teaser

Captain Kirk and his infamous Gorn antagonist from the original series have it out again in this light-hearted ad for the new "Star Trek: The Video Game." Will they never bury the hatchet?

The Gorn are an alien species, reptilian and of great strength, one of which Kirk battled in an excellent demonstration of Starfleet martial superiority. It turns out Gorn aren't so great to have on your team, either, as the reprise of the match-up demonstrates.

While the game footage shown in the commercial looks like something out of the early 2000s, the ad is charming and may convince fans that "Star Trek: The Video Game" at least has its heart in the right place. The game arrives April 23 for Xbox 360 and PS3.

Hubble observes the hidden depths of Messier 77

Friday, March 29, 2013

Messier 77 is a galaxy in the constellation of Cetus, some 45 million light-years away from us. Also known as NGC 1068, it is one of the most famous and well-studied galaxies. It is a real star among galaxies, with more papers written about it than many other galaxies put together!

Despite its current fame and striking swirling appearance, the galaxy has been a victim of mistaken identity a couple of times; when it was initially discovered in 1780, the distinction between gas clouds and galaxies was not known, causing finder Pierre Mechain to miss its true nature and label it as a nebula. It was misclassified again when it was subsequently listed in the Messier Catalogue as a star cluster.

Now, however, it is firmly categorised as a barred spiral galaxy, with loosely wound arms and a relatively small central bulge. It is the closest and brightest example of a particular class of galaxies known as Seyfert galaxies -- galaxies that are full of hot, highly ionised gas that glows brightly, emitting intense radiation.

Strong radiation like this is known to come from the heart of Messier 77 -- caused by a very active black hole that is around 15 million times the mass of our Sun. Material is dragged towards this black hole and circles around it, heating up and glowing strongly. This region of a galaxy alone, although comparatively small, can be tens of thousands of times brighter than a typical galaxy.

Although no competition for the intense centre, Messier 77's spiral arms are also very bright regions. Dotted along each arm are knotty red clumps -- a signal that new stars are forming. These baby stars shine strongly, ionising nearby gas which then glows a deep red colour as seen in the image above. The dust lanes stretching across this image appear as a rusty, brown-red colour due to a phenomenon known as reddening; the dust absorbs more blue light than red light, enhancing its apparent redness.

DLink ships its AC1200 dualband 80211n router  coffee mug impersonator

True, D-Link's AC1200 may better resemble the container keeping your coffee hot at work than a traditional WiFi router, but it remains a rare take on networking design that's frankly appreciated. We're glad to report, then, that it's shipping to stores. The device (seen in the middle) is the more affordable of D-Link's two 2013-era 802.11ac routers at its $130 street price, keeping costs in check by peaking at at more modest 867Mbps speed with the new standard and 300Mbps on old-fashioned 802.11n. It still dishes out wireless on either the 2.4GHz or 5GHz bands, offers wired connections to four gigabit Ethernet devices and shares content from drives attached to its lone USB 3.0 port. When devices like the HTC One and Galaxy S 4 are arriving with 802.11ac built-in, we'd say the AC1200 is a timely solution -- just don't pack it with your office lunch.

New vaccine-design approach targets viruses such as HIV

Mar. 28, 2013 ? A team led by scientists from The Scripps Research Institute (TSRI) and the International AIDS Vaccine Initiative (IAVI) has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.

The report, which appears March 28, 2013, in Science Express, the early online edition of the journal Science, offers a step toward solving what has been one of the central problems of modern vaccine design: how to stimulate the immune system to produce the right kind of antibody response to protect against a wide range of viral strains. The researchers demonstrated their new technique by engineering an immunogen (substance that induces immunity) that has promise to reliably initiate an otherwise rare response effective against many types of HIV.

"We're hoping to test this immunogen soon in mice engineered to produce human antibodies, and eventually in humans," said team leader William R. Schief, who is an associate professor of immunology and member of the IAVI Neutralizing Antibody Center at TSRI.

Seeking a Better Way

For highly variable viruses such as HIV and influenza, vaccine researchers want to elicit antibodies that protect against most or all viral strains -- not just a few strains, as seasonal flu vaccines currently on the market. Vaccine researchers have identified several of these broadly neutralizing antibodies from long-term HIV-positive survivors, harvesting antibody-producing B cells from blood samples and then sifting through them to identify those that produce antibodies capable of neutralizing multiple strains of HIV. Such broadly neutralizing antibodies typically work by blocking crucial functional sites on a virus that are conserved among different strains despite high mutation elsewhere.

However, even with these powerful broadly neutralizing antibodies in hand, scientists need to find a way to elicit their production in the body through a vaccine. "For example, to elicit broadly neutralizing antibodies called VRC01-class antibodies that neutralize 90 percent of known HIV strains, you could try using the HIV envelope protein as your immunogen," said Schief, "but you run into the problem that the envelope protein doesn't bind with any detectable affinity to the B cells needed to launch a broadly neutralizing antibody response."

To reliably initiate that VRC01-class antibody response, Schief and his colleagues therefore sought to develop a new method for designing vaccine immunogens.

From Weak to Strong

Joseph Jardine, a TSRI graduate student in the Schief laboratory, evaluated the genes of VRC01-producing B cells in order to deduce the identities of the less mature B cells -- known as germline B cells -- from which they originate. Germline B cells are major targets of modern viral vaccines, because it is the initial stimulation of these B cells and their antibodies that leads to a long-term antibody response.

In response to vaccination, germline B cells could, in principle, mature into the desired VRC01-producing B cells -- but natural HIV proteins fail to bind or stimulate these germline B cells so they cannot get the process started. The team thus set out to design an artificial immunogen that would be successful at achieving this.

Jardine used a protein modeling software suite called Rosetta to improve the binding of VRC01 germline B cell antibodies to HIV's envelope protein. "We asked Rosetta to look for mutations on the side of the HIV envelope protein that would help it bind tightly to our germline antibodies," he said.

Rosetta identified dozens of mutations that could help improve binding to germline antibodies. Jardine then generated libraries that contained all possible combinations of beneficial mutations, resulting in millions of mutants, and screened them using techniques called yeast surface display and FACS. This combination of computational prediction and directed evolution successfully produced a few mutant envelope proteins with high affinity for germline VRC01-class antibodies.

Jardine then focused on making a minimal immunogen -- much smaller than HIV envelope -- and so continued development using the "engineered outer domain (eOD)" previously developed by Po-Ssu Huang in the Schief lab while Schief was at the University of Washington. Several iterative rounds of design and selection using a panel of germline antibodies produced a final, optimized immunogen -- a construct they called eOD-GT6.

A Closer Look

To get a better look at eOD-GT6 and its interaction with germline antibodies, the team turned to the laboratory of Ian A. Wilson, chair of the Department of Integrative Structural and Computational Biology and a member of the IAVI Neutralizing Antibody Center at TSRI.

Jean-Philippe Julien, a senior research associate in the Wilson laboratory, determined the 3D atomic structure of the designed immunogen using X-ray crystallography -- and, in an unusual feat, also determined the crystal structure of a germline VRC01 antibody, plus the structure of the immunogen and antibody bound together.

"We wanted to know whether eOD-GT6 looked the way we anticipated and whether it bound to the antibody in the way that we predicted -- and in both cases the answer was 'yes'," said Julien. "We also were able to identify the key mutations that conferred its reactivity with germline VRC01 antibodies."

Mimicking a Virus

Vaccine researchers know that such an immunogen typically does better at stimulating an antibody response when it is presented not as a single copy but in a closely spaced cluster of multiple copies, and with only its antibody-binding end exposed. "We wanted it to look like a virus," said Sergey Menis, a visiting graduate student in the Schief laboratory.

Menis therefore devised a tiny virus-mimicking particle made from 60 copies of an obscure bacterial enzyme and coated it with 60 copies of eOD-GT6. The particle worked well at activating VRC01 germline B cells and even mature B cells in the lab dish, whereas single-copy eOD-GT6 did not.

"Essentially it's a self-assembling nanoparticle that presents the immunogen in a properly oriented way," Menis said. "We're hoping that this approach can be used not just for an HIV vaccine but for many other vaccines, too."

The next step for the eOD-GT6 immunogen project, said Schief, is to test its ability to stimulate an antibody response in lab animals that are themselves engineered to produce human germline antibodies. The difficulty with testing immunogens that target human germline antibodies is that animals typically used for vaccine testing cannot make those same antibodies. So the team is collaborating with other researchers who are engineering mice to produce human germline antibodies. After that, he hopes to learn how to drive the response, from the activation of the germline B cells all the way to the production of mature, broadly neutralizing VRC01-class antibodies, using a series of designed immunogens.

Schief also hopes they will be able to test their germline-targeting approach in humans sooner rather than later, noting "it will be really important to find out if this works in a human being."

The first authors of the paper, "Rational HIV immunogen design to target specific germline B cell receptors," were Jardine, Julien and Menis. Co-authors were Takayuki Ota and Devin Sok of the Nemazee and Burton laboratories at TSRI, respectively; Travis Nieusma of the Ward laboratory at TSRI; John Mathison of the Ulevitch laboratory at TSRI; Oleksandr Kalyuzhniy and Skye MacPherson, researchers in the Schief laboratory from IAVI and TSRI, respectively; Po-Ssu Huang and David Baker of the University of Washington, Seattle; Andrew McGuire and Leonidas Stamatatos of the Seattle Biomedical Research Institute; and TSRI principal investigators Andrew B. Ward, David Nemazee, Ian A. Wilson, and Dennis R. Burton, who is also head of the IAVI Neutralizing Center at TSRI.

The project was funded in part by IAVI; the National Institutes of Health (AI84817, AI081625 and AI33292); and the Ragon Institute.

Recyclable organic solar cells: a clean fuel future made possible by trees

Solar cells are made from trees

You don't have to know Shel Silverstein to know that trees are exceptionally giving. They're responsible for our homes, paper, air, furniture and, now, energy -- the "clean" kind, that is. Researchers from the Georgia Institute of Technology and Purdue University have jointly devised a patent-pending method to build organic solar cells using plant-derived substrates. Known as cellulose nanocrystal substrates (or CNC), these solar cells benefit from being truly disposable, eliminating the waste that results from the use of alternative materials like petroleum or glass. The CNC-made cells are not only transparent enough to allow light to pass into an embedded semiconductor, but they also dissolve when submerged into water, thus earning the esteemed recyclable distinction.

Although this is undoubtedly a breakthrough for clean energy tech, it's by no means a near-future reality. Apparently, current cells can only yield a 2.7-percent conversion efficiency rate, which falls far below the 10-percent threshold met by rival fabrication methods (i.e., petroleum and glass). So, there's still significant work to be done before the team can improve production and achieve parity with those less "recyclable" options. Until that time, consider this a comforting reassurance that a clean fuel era is well within reach.

NKorean defector groups report computer attacks

(AP) ? Websites and organizations run by North Korean defectors in South Korea say they have suffered cyberattacks, one week after computer systems at some South Korean banks and TV networks were widely disrupted.

Daily NK, which posts news about North Korea, says it experienced a cyperattack Tuesday, while South Korea's Yonhap news agency says that Free North Korea Radio was also attacked.

Daily NK says its site was temporarily paralyzed by a cyberattack that was routed through the United States. It says some access was restored about an hour later but the attacks were continuing.

Yonhap says a computer network used by seven local governments was also briefly attacked, as was a network belonging to broadcaster YTN.

Authorities have not confirmed who was behind last week's cyberattack but suspect North Korea.

(AP Photo/Carolyn Kaster)

(AP) ? In a major gay rights case, the Supreme Court indicated Wednesday it could strike down the law that prevents legally married gay couples from receiving a range of federal benefits that go to other married people.

Justice Anthony Kennedy, often the decisive vote in close cases, joined the four more liberal justices in raising questions about a provision of the federal Defense of Marriage Act that is being challenged at the court.

Kennedy said the law appears to intrude on the power of states that have chosen to recognize same-sex marriages. Other justices said the law creates what Justice Ruth Bader Ginsburg called two classes of marriage, full and "skim-milk marriage."

The federal law affects a range of benefits available to married couples, including tax breaks, survivor benefits and health insurance for spouses of federal employees.

It still is possible the court could dismiss the case for procedural reasons, though that prospect seemed less likely than it did in Tuesday's argument over gay marriage in California.

The motivation behind the 1996 federal law, passed by large majorities in Congress and signed by President Bill Clinton, was questioned repeatedly by Justice Elena Kagan.

She read from a House of Representatives report explaining that the reason for the law was "to express moral disapproval of homosexuality." The quote produced an audible reaction in the courtroom.

Paul Clement, representing the House Republican leadership in defending the law, said the more relevant question is whether Congress had "any rational basis for the statute." He supplied one, the federal government's interest in treating same-sex couples the same no matter where they live.

Clement said the government does not want military families "to resist transfer from West Point to Fort Sill because they're going to lose their benefits." The U.S. Military Academy at West Point is in New York, where same-sex marriage is legal, and Fort Sill is in Oklahoma, where gay marriages are not legal.

Opposing Clement was the Obama administration's top Supreme Court lawyer, Donald Verrilli, who said the provision of DOMA at issue, Section 3, impermissibly discriminates against gay people.

"This statute is not called the Federal Uniform Benefits Act," Verrilli said. The administration wants the court to apply a level of scrutiny it applies to discrimination against other disadvantaged groups and that makes it harder for governments to justify those laws.

Both Verrilli and Roberta Kaplan, the lawyer for the 83-year-old New Yorker who sued over DOMA, told the court that views about gay people and marriage have shifted dramatically since 1996.

"Why are you so confident in that judgment? How many states" allow same-sex unions? Justice Antonin Scalia asked Kaplan.

Nine, she said.

"So there's been a sea change since 1996," Scalia said, doubtfully.

But Chief Justice John Roberts jumped on the idea of a rapid shift in opinion to suggest that perhaps gays and lesbians do not need special protection from the court.

"As far as I can tell, political leaders are falling all over themselves to endorse your side of the case," Roberts said.

The justices stepped into the dispute after lower federal courts ruled against the measure.

The DOMA argument followed Tuesday's case over California's ban on same-sex marriage, a case in which the justices indicated they might avoid a major national ruling on whether America's gays and lesbians have a right to marry. Even without a significant ruling, the court appeared headed for a resolution that would mean the resumption of gay and lesbian weddings in California.

Marital status is relevant in more than 1,100 federal laws that include estate taxes, Social Security survivor benefits and health benefits for federal employees. Lawsuits around the country have led four federal district courts and two appeals courts to strike down the law's Section 3, which defines marriage. In 2011, the Obama administration abandoned its defense of the law but continues to enforce it.

Same-sex marriage is legal in nine states and the District of Columbia. The states are Connecticut, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont and Washington. It was legal in California for less than five months in 2008.

The justices chose for their review the case of Edith Windsor, 83, of New York, who sued to challenge a $363,000 federal estate tax bill after her partner of 44 years died in 2009.

Windsor, who goes by Edie, married Thea Spyer in 2007 in Canada after doctors told them that Spyer would not live much longer. She suffered from multiple sclerosis for many years. Spyer left everything she had to Windsor.

There is no dispute that if Windsor had been married to a man, her estate tax bill would have been zero.

The U.S. 2nd Circuit Court of Appeals in New York agreed with a district judge that the provision of DOMA deprived Windsor of the constitutional guarantee of equal protection of the law.

Like the Proposition 8 case from California, Windsor's lawsuit could falter on a legal technicality without a definitive ruling from the high court.

The House Republicans, the Obama administration and a lawyer appointed by the court especially to argue the issue spent the first 50 minutes Wednesday discussing whether the House Republican leadership can defend the law in court because the administration decided not to, and whether the administration forfeited its right to participate in the case because it changed its position and now argues that the provision is unconstitutional.

If the Supreme Court finds that it does not have the authority to hear the case, Windsor probably would still get her refund because she won in the lower courts. But there would be no definitive decision about the law from the nation's highest court, and it would remain on the books.

Roberts and Scalia seemed most interested in this sort of outcome.

On Tuesday, the justices weighed a fundamental issue: Does the Constitution require that people be allowed to marry whom they choose, regardless of either partner's gender? The fact that the question was in front of the Supreme Court at all was startling, given that no state recognized same-sex unions before 2003 and 40 states still don't allow them.

But it was clear from the start of that argument in a packed courtroom that the justices, including some liberals who seemed open to gay marriage, had doubts about whether they should even be hearing the challenge to California's Proposition 8, the state's voter-approved gay marriage ban.

Kennedy suggested the justices could dismiss the case with no ruling at all.

Such an outcome would almost certainly allow gay marriages to resume in California but would have no impact elsewhere.

There was no majority apparent for any particular outcome, and many doubts were expressed by justices about the arguments advanced by lawyers for the opponents of gay marriage in California, by the supporters and by the Obama administration, which is in favor of same-sex marriage rights. The administration's entry into the case followed President Barack Obama's declaration of support for gay marriage.

Reflecting the high interest in the cases, the court released an audio recording of Wednesday's argument, just as it did Tuesday.

A somewhat smaller crowd gathered outside the court Wednesday, mainly gay marriage supporters who held American and rainbow flags. "Two, four, six, eight, we do not discriminate," a group chanted at one point. "If this isn't the time, when is the time? When does equality come into play?" asked Laura Scott, 43, of Columbia, Md.

Woods back on top in golf

(AP) ? The moment was vintage Tiger Woods, and so was his reaction.

Seconds after Rickie Fowler made a 40-foot birdie putt on the 12th hole to pull within two shots of the lead, Woods posed over his 25-foot birdie putt until he swept the putter upward in his left hand and marched toward the cup as it dropped for a birdie.

Fowler, standing on the edge of the green, turned with a slight smile as if to say, "What else can I do?"

Woods won the Arnold Palmer Invitational on Monday and returned to No. 1 in the world for the first time since October 2010, the longest spell of his career. After all that time, after so much turmoil with his personal life and his health, Woods looks as good as ever.

Maybe better.

"It's a byproduct of hard work, patience and getting back to winning golf tournaments," Woods said.

He essentially wrapped up his eighth title at Bay Hill with an 8-iron out of a fairway bunker on the par-5 16th that easily cleared the water and landed safely on the green for a two-putt birdie. Woods dangled his tongue out of his mouth as the ball was in the air, another sign of his swagger.

Just like his other two wins this year, Woods never let anyone get closer than two shots in the final round. With a conservative bogey he could afford on the final hole, he closed with a 2-under 70 for a two-shot win over Justin Rose.

Woods walked off the 18th green waving his putter over his head ? truly a magic wand at Bay Hill ? to acknowledge the fans who have seen this act before. His eighth win in the Arnold Palmer Invitational tied a PGA Tour record that had not been touched in 48 years.

This win had extra significance. He's back to No. 1.

"If I get healthy, I know I can play this game at a high level," Woods said. "I know I can be where I'm contending in every event, contending in major championships and being consistent day in and day out ? if I got healthy. That was the first step in the process. Once I got there, then my game turned."

A year ago, he came to Bay Hill without having won in more than 2? years. He left this year having won six times in his last 20 starts on the PGA Tour.

Next up is the Masters, where Woods will try to end his five-year drought in the majors.

"I'm really excited about the rest of this year," Woods said.

Woods fell as low as No. 58 in the world as he coped with the collapse of his marriage, a loss of sponsors and injuries to his left leg. One week after he announced he was dating Olympic ski champion Lindsey Vonn, Woods returned to the top of golf.

"Number 1 !!!!!!!!!!!!!" Vonn tweeted moments after his win.

Asked if there was any correlation to his winning right after going public with his relationship, Woods smiled and said, "You're reading way too much into this."

Like so many other victories, this one was never really close.

Fowler pulled to within two shots with a 25-foot birdie putt on the 14th hole, but after he and Woods made bogey on the 15th, Fowler went at the flag on the par-5 16th and came up a few yards short and into the water. Fowler put another ball into the water and made triple bogey.

"I was swinging it well. I made a few putts, and trying to put a little pressure on them, let them know I was there," Fowler said. "Just would like to have that 7-iron back on 16. Just kind of a touch heavy."

Woods played it safe on the 18th, and nearly holed a 75-foot par putt that even drew a big smile from the tournament host.

Woods tied the tour record of eight wins in a single tournament. Sam Snead won the Greater Greensboro Open eight times from 1938 to 1965 at two golf courses. Woods tied his record for most wins at a single golf course, having also won eight times at Torrey Pines, including a U.S. Open.

"I don't really see anybody touching it for a long time," Palmer said while Woods made his way up the 18th fairway. "I had the opportunity to win a tournament five times, and I knew how difficult that was."

Rose, who played the first two rounds with Woods, closed with a 70 to finish alone in second.

He pulled to within two shots of Woods with a birdie on the 16th. Woods was in the group behind him in the fairway bunker on the par 5, and hit 8-iron over the water and onto the middle of the green for a two-putt birdie to restore his margin.

"He plays every shot like he plays them on Sunday," Rose said. "His intensity is the same on Thursday often as it is on Sunday, and that makes Sunday a lot less different for him. He plays in that kind of atmosphere far more regularly than a lot of guys do, and it's an adjustment for most of us. It's a known for him."

Fowler had to settle for a 73 and a tie for third with Mark Wilson (71), Keegan Bradley (71) and Gonzalo Fernandez-Castano (72).

Rory McIlroy had been No. 1 since he won the PGA Championship last August. He can reclaim the No. 1 ranking by winning the Houston Open this week. Woods heads home to south Florida for two weeks before the Masters.

Asked the last time he felt this good going to Augusta National, Woods replied, "It's been a few years."

This was the fourth time in his career that he already had three PGA Tour wins before the Masters ? he didn't win a green jacket in any of the previous years (2000, 2003 and 2008). More telling, perhaps, is that Woods has won back-to-back starts for the first time since the Buick Open and Bridgestone Invitational in August 2009.

"I think it shows that my game is consistent," he said. "It's at a high level."

Woods finished at 13-under 275 and won for the 77th time on the PGA Tour, moving to within five of Snead's record.

Fowler, his first time playing with Woods in the final group, opened with eight pars when he needed to be making up ground. And when he finally had a few openings on the back nine, Woods refused to let him through.

Woods salvaged a two-putt par with a 7-footer on the 11th hole to keep a three-shot lead. On the next hole, Fowler looked to gain some momentum when he made a 40-foot birdie putt only for Woods to match him with that 25-foot birdie.

Woods produced some absurd statistics with the putter this week, making 19 of 28 putts from between 7 feet and 20 feet.

He walked off the green to share a handshake with Palmer, along with a big smile and some words that Woods said were best kept private. He left the course in that familiar blue blazer that goes to the winner.

And he left as the No. 1 player in the world.

It's the 11th time that Woods has gone back to No. 1, tied with Greg Norman since the ranking began in 1986. Still to be determined is how long Woods stays there this time.

Uber lands on Windows Phone, expands its on-demand car service dominance

Uber lands on Windows Phone, expands its ondemand car service dominance

Windows Phone owners can finally enjoy all the benefits of Uber and order cabs on demand through their own native app. The basic features are all present, just presented in the stark color blocks and straight lines Microsoft favors. You'll need to have either version 7.5 or 8 of the OS installed to download the app and, of course, you'll need to live in a city where the service is available to take advantage. The expansion to Windows Phone follows last week's quiet debut on BlackBerry (which the company only announced today), though it's currently only available on older devices and not compatible with BlackBerry 10. It was also just last week that Uber launched a redesigned Android client that was rebuilt from the ground up with improved performance, Foursquare integration and a fare estimator. It seems like Uber is looking to establish an insurmountable lead in the market before any competitors get any grand ideas.

Crowds pray with Pope Francis at start of holy week

Alessandra Tarantino / AP

Pope Francis arrives in St. Peter's Square at the Vatican on Sunday.

By F. Brinley Bruton, Staff Writer, NBC News

Crowds gathered in the Vatican to witness Pope Francis's first Palm Sunday celebration marking the start of the holy week of Easter in celebration of the crucifixion and resurrection of Jesus Christ.?

Tens of thousands of pilgrims gathered in St. Peter's Square to be part of the Catholic Church's most important liturgical season. Sprigs of olive trees were distributed to the faithful in remembrance of Jesus' triumphant entry into Jerusalem before his crucifixion.

The new pontiff arrived in an uncovered car to start the ceremonies. Wearing bright red robes over a white cassock, Francis then walked along St. Peter's holding a palm frond and presided over the Mass from an altar sheltered by a canopy on the steps of St. Peter's Basilica.?

After Sunday's Mass, the Pope Francis will lead six more liturgies during the week, culminating with the Easter Sunday Mass and Urbi et Orbi blessing

On Saturday, Pope Francis and his predecessor Benedict prayed together before having lunch in a historic meeting.

The new pontiff had flown to the papal residence at Castel Gandolfo in the Alban Hills outside of Rome by helicopter. Pope Benedict XVI has been living there since he resigned Feb. 28, becoming the first pope to step down in 600 years.Both men wore white papal outfits.

Father Federico Lombardi, a Vatican spokesman, said that Benedict and Francis had embraced at the helipad, then went to a private chapel to pray.

March Madness App Brings Its 'A' Game

US, Afghanistan OK detention center transfer

WASHINGTON (AP) ? The U.S. has reached an agreement with the Afghanistan government to transfer the Parwan Detention Facility to Afghan control, the Pentagon said Saturday, two weeks after negotiations broke down over whether the U.S. would have the power to block the release of some detainees.

According to a senior U.S. official, a key element to the agreement is that the Afghans can invoke a procedure that insures prisoners considered dangerous would not be released. The agreement also includes a provision that allows the two sides to work together to resolve any differences. The official lacked authorization to discuss the details of the agreement publicly and spoke on condition of anonymity.

Transfer of the Parwan detention center is critical to the ongoing effort to gradually shift control of the country's security to the Afghans as the U.S. and allies move toward the full withdrawal of combat troops by the end of 2014.

Afghans demanded control of the center, but U.S. officials have worried that the most threatening detainees would be freed once the U.S. transferred control. Defense Secretary Chuck Hagel spoke with Afghan President Hamid Karzai Saturday as officials finalized the agreement after days of intense negotiations.

The senior official said U.S. and Afghan officials who are familiar with the detainees would meet to assess the potential danger of their release to coalition forces. The official said that more senior level officials could be brought in if there are disagreements but that to date the two sides have been able to agree without bringing in those higher authorities.

Disagreements over the detention facility, which also included whether Afghans can be held without trial, had thrown a pall over the ongoing negotiations for a bilateral security agreement that would govern the presence of U.S. forces in Afghanistan after 2014.

Currently, there is an Afghan administrator of the Parwan prison, but the Americans have power to veto the release of detainees. The prisoners held under American authority do not have the right to a trial because the U.S. considers them part of an ongoing conflict.

Pentagon press secretary George Little said Hagel "welcomed President Karzai's commitment that the transfer will be carried out in a way that ensures the safety of the Afghan people and coalition forces by keeping dangerous individuals detained in a secure and humane manner in accordance with Afghan law."

Last weekend Hagel spoke with Karzai, and officials said the two men agreed to resolve the thorny issue within a week.

The top U.S. commander in Afghanistan, Marine Gen. Joseph Dunford, has also been working to resolve the matter ? one of several divisive issues that soured relations between the U.S., its allies and the Afghans in recent weeks.

The U.S. had been scheduled to hold a ceremony marking the transfer of control two weeks ago, during Hagel's first visit to Afghanistan as defense secretary. That ceremony was called off after negotiations broke down.

In addition to disputes over the Parwan facility, the U.S.-led coalition and Afghans have wrangled over several other difficult issues. Last month, Karza insisted that the coalition forces cease all airstrikes, after a NATO assault caused civilian casualties.

More recently, Karzai demanded that U.S. special operations forces leave Wardak province after allegations that U.S. commandos and their Afghan partners abused local citizens. Dunford has denied the charges.

Earlier this week, the two sides reached an agreement on the Warkak issue. Dunford agreed to remove a team of commandos from Wardak's Nirkh district and transition security of that area to the Afghans as soon as possible.

U.S. special operations forces would remain in other parts of the restive province, while the coalition continues to work to transition those areas also to the Afghans.

U.S. officials have made no final decision on how many troops might remain in Afghanistan after 2014, although they have said as many as many as 12,000 U.S. and coalition forces could remain.

There currently are 66,000 U.S. troops in Afghanistan, down from a 2010 peak of 100,000.
