SIA to recruit & train intern cabin crew from polys






SINGAPORE: Singapore Airlines (SIA) is working closely with three polytechnics to recruit and train cabin crew, as part of efforts to attract the best talent.

It has special programmes with Nanyang Polytechnic, Republic Polytechnic and Temasek Polytechnic, covering recruitment activities.

It's also starting an internship-recruitment programme to hire and train selected students to become full-time cabin crew.

These are provided under Memoranda of Understanding (MOUs) that the carrier signed with the three polytechnics on Thursday.

Besides recruitment, the MOUs also cover areas of potential cooperation such as curriculum development in service, operations, safety and security.

SIA will also work with the polytechnics on continued education programmes for cabin crew.

SIA employs about 7,500 cabin crew. New crew undergo an extensive 15-week training programme in areas such as service delivery, customer relations, deportment, security and safety.

Latino should have played lead in 'Argo'




Ben Affleck plays the lead role of Tony Mendez in "Argo," which he also directed.




STORY HIGHLIGHTS


  • Oscar nominations on Thursday, and Ben Affleck expected to get one for "Argo"

  • Affleck plays real-life Latino who helped diplomats escape in Iran hostage crisis

  • Ruben Navarrette: Affleck should have used a Latino actor to play role

  • He says it cheats actor out of a job, and the Latino community out of a hero's story




San Diego, California (CNN) -- The upcoming Oscars are no stranger to causes or controversy. And this year, there is a strong dose of both surrounding the film "Argo" -- and its star and director, Ben Affleck.


This controversy bubbled up when the buzz started that Affleck could get an Academy Award nomination for best director when the announcements are made Thursday.


"Argo" tells how an ingenious and daring CIA agent helped orchestrate the rescue of six U.S. diplomats from Tehran during the Iran hostage crisis of 1979-1980. In November 1979, about 300 Islamic students stormed the U.S. Embassy and 66 Americans were taken hostage. But six U.S. diplomats escaped and were hidden at the Canadian Embassy by the Canadian ambassador and his wife.

The CIA agent -- Antonio "Tony" Mendez, played by Affleck -- successfully led the mission to evacuate the Americans, which involved Mendez and his associates posing as a Canadian film crew that was eager to make a movie in Iran.


The real Tony Mendez was awarded the Intelligence Star for Valor, and other honors, for leading the rescue. He later wrote a memoir, detailing the events in Tehran.








"Argo" is loosely based on Mendez's book. Better make that, very loosely based. As movie critics and others have pointed out since the movie opened a few months ago, the filmmakers took lots of dramatic license with the story. Mendez's role is played up, while that of the Canadians who helped hide and protect the Americans is played down. Some scenes depicted in the film never happened. Some characters are composites of several real people.


In other words, it's what you would expect from a Hollywood feature film based on a historical event. It's not a documentary. It's meant to be taken with a grain of salt, and to be entertaining.


Still, there are some Latinos -- in and out of Hollywood -- who think that, in this case, the filmmakers, and especially Affleck, pushed the concept of creativity too far. They say Affleck missed an opportunity to put more Latinos on screen. Moreover, they say, Affleck improperly claimed, for himself, the choice role of Mendez when he should have cast a Latino actor instead. They insist that the director didn't just cheat a Latino out of an acting job but the Latino community out of a feel-good story about one of their own who won acclaim for a heroic deed.


The critics are right, and their cause is just. Affleck should have tried to cast a Latino to play Mendez. That's common sense, and it would have made "Argo" a better movie. Affleck also didn't do himself any favors by trying to dismiss the criticism with a glib remark that essentially said that it really doesn't matter that the actor playing Mendez isn't Latino since Mendez himself isn't, shall we say, overtly Latino.


At a recent forum intended to publicize the film, Affleck responded to a question from the audience about the controversy by noting that "Tony does not have, I don't know what you would say, a Latin/Spanish accent" and that "You wouldn't necessarily select him out of a line of 10 people and go 'This guy's Latino.' "


Ouch. At least Affleck didn't slip and say "line up."


"So I didn't feel as though I was violating something," he said, "where, here's this guy who's clearly ethnic in some way and it's sort of being whitewashed by Ben Affleck the actor."


Johnny Depp set a better example. Several months ago, Depp turned down the role of Mexican revolutionary Francisco "Pancho" Villa in another film. He said that the role should go to a Latino. I praised Depp at the time for showing that, besides being a great actor, he is also a person of character.


The exclusion of Latinos from Hollywood is an old story. This is still a black and white world, where Latinos rarely get cast in the leading role. We're the gardeners and housekeepers, the gang leader and drug dealers, the nannies and farm workers. That's it. There has been some progress, of course. But not enough -- not when you have a Latina in the Supreme Court, three Latinos in the U.S. Senate, and Latinos heading Fortune 500 companies.


I could blame the environment of Southern California, in which most Hollywood writers, producers and directors live and spend most of their time. When they get up in the morning and drive to work, most Latinos they encounter are subservient. We clean their homes, cook their breakfast, trim their hedges, park their cars and otherwise help them get through the day.


Still, you can push this argument too far, and wind up going down a dangerous path -- one that ultimately sets back the greater cause of trying to get television networks and film studios to create a broader range of meatier roles for Latino actors and actresses.


After all, it's a short walk from saying that a director should have cast a Latino to play a Latino to arguing that only Latinos can play Latinos. And, if that's the argument, then on what moral high ground do Latinos stand to also push -- as we should -- for Latino actors and actresses to be considered for generic and mainstream roles that could have gone to white actors? We can't have it both ways.


Even if Latinos succeed in making their point about this one director and this one movie, it could backfire. We could win this battle, and still lose the war.


But before Latinos can be fully integrated into America and not considered outsiders, we have to take every opportunity to push for inclusion and fairness. And acknowledging that Latinos have the skills to play themselves is a good start.

FBI probes cyber threats against Steubenville sheriff

Jefferson County Sheriff Fred Abdalla talks about how the FBI is investigating cyber threats in the eastern Ohio city that include a death threat received by the sheriff in his office on Wednesday, Jan. 9, 2013, in Steubenville, Ohio. / AP Photo/Keith Srakocic

STEUBENVILLE, OhioThe FBI is investigating cyber threats in an eastern Ohio city that include death threats against the local sheriff's family and an email that apparently shut down the police chief's computer.

Leaked video shows teens joking about Ohio rape case



The threats are part of a series of online messages that have targeted individuals and authorities in Steubenville amid increased attention over two high school football players who are facing rape charges.

Jefferson County Sheriff Fred Abdalla said Wednesday he'd provided the FBI a copy of an anonymous Facebook post in which someone threatened to kill his family.

Steubenville Police Chief William McCafferty said he gave the FBI an email that he had opened Wednesday morning, which then disabled his computer.

FBI spokesman Todd Lindgren said he could not immediately comment.



The two teenage boys are set for trial next month in juvenile court on charges they raped a 16-year-old in August. Their attorneys have denied the charges in court.



Much of the evidence in the case played out on social media, in which the photos of the seemingly unconscious girl were posted online. A video published and then deleted from YouTube shows a third freshman, Michael Nodianos, joking about the alleged rape.



The hacking collective Anonymous has staged rallies in support of the alleged victim, and hackers were able to dig up and re-post the deleted YouTube video online.



According to the Steubenville Herald Star, Nodianos' attorney said someone hacked into his client's email and social media accounts, as well as the email accounts of his family members. He has since dropped out of Ohio State University, where he was slated to attend on a scholarship.

Pruney fingers give us better grip underwater









































WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.












Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.












To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.












With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.












So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Football: Liga-dominated FIFPro World XI raises eyebrows






LONDON: With Spanish clubs having supplied all 11 members of the FIFPro World XI for 2012, La Liga's claim to be considered the world's best league appears stronger than ever.

Barcelona and Real Madrid may have missed out in last season's Champions League, losing to Chelsea and Bayern Munich respectively, but they still supplied 10 of the players voted into FIFA's all-star team by over 55,000 professional footballers around the world.

Atletico Madrid's Colombian striker Radamel Falcao completed the line-up, meaning that for the first time in the eight-year history of the selection, all 11 players were drawn from teams playing in the same country.

In recent years, coinciding with Spain's dominance of both club and international football, the make-up of the FIFPro World XI has crystallised around a small coterie of players.

Serial Ballon d'Or-winner Lionel Messi has been a mainstay of the side since 2007, Iker Casillas and Xavi since 2008, and Andres Iniesta and Cristiano Ronaldo have been included in the team for the past four years.

In fact, so enduring is the appeal of the players at Spain's top two clubs that there were only two changes to the 11 voted into the FIFPro World XI in 2011.

Manchester United pair Wayne Rooney and Nemanja Vidic were the men to make way, for Falcao and Madrid's Brazilian left-back Marcelo, as the English Premier League had its grip on the team prised away finger by finger.

England has at least mustered representation in recent years, which is more than can be said for the German Bundesliga and France's Ligue 1, while the leading lights from Italy's Serie A have been ignored since 2010.

Amid criticism that the FIFPro selection amounts to nothing more than a glorified popularity contest, dissenting voices have emerged.

Germany captain Lothar Matthaus, present at the Ballon d'Or ceremony in Zurich, claims "people were shaking their heads" when the line-up was announced, while Chelsea left-back Ashley Cole jokingly tweeted: "#iwantspanishpassport."

Given the Spanish national team's stellar achievements in 2012 and the enduring brilliance of Messi and Ronaldo, it is difficult to quibble with much of the team, but there is room for conjecture.

Xabi Alonso won the league with Madrid and scored twice against France in the Euro 2012 quarter-finals, but his performances in Poland and Ukraine were eclipsed by those of Italy's Andrea Pirlo.

The elegant Juventus midfielder narrowly missed out to Iniesta in the voting for the player of the tournament and UEFA technical director Andy Roxburgh described his displays as "magnificent".

His Italy and Juve team-mates Gianluigi Buffon and Giorgio Chiellini also enjoyed excellent years, including success in Serie A, although both were members of the back line pierced four times by Spain in the Euro 2012 final.

In attack, Manchester United striker Robin van Persie, Zlatan Ibrahimovic of Paris Saint-Germain and Chelsea's Champions League hero Didier Drogba all presented strong cases for inclusion as well, albeit not with a Spanish accent.

FIFPro World XI 2012:

Iker Casillas (ESP/Real Madrid); Dani Alves (BRA/Barcelona), Gerard Pique (ESP/Barcelona), Sergio Ramos (ESP/Real Madrid), Marcelo (BRA/Real Madrid); Xabi Alonso (ESP/Real Madrid), Xavi (ESP/Barcelona), Andres Iniesta (ESP/Barcelona); Lionel Messi (ARG/Barcelona), Radamel Falcao (COL/Atletico Madrid), Cristiano Ronaldo (POR/Real Madrid)

Why 'Django' stirs race debate






STORY HIGHLIGHTS


  • Gene Seymour: Spike Lee, Quentin Tarantino spatting over "Django Unchained"

  • Seymour says film, which upends slavery narrative, is classic comic-book Tarantino

  • He says debate is over whether white artists have right to tell any part of black American story

  • Seymour notes James Baldwin's sound advice: "If you don't like their alternative, write yours"




Editor's note: Gene Seymour is a film critic who has written about music, movies and culture for The New York Times, Newsday, Entertainment Weekly and The Washington Post.


(CNN) -- Spike Lee says he's never going to see Quentin Tarantino's "Django Unchained" because he's certain it is "disrespectful of my ancestors." Tarantino says he doesn't need to waste time responding to Lee's accusation. That, as they say, is that.


So why do we insist on staring at two egomaniacs staring down each other?


Race. Again. The subject that never fails to provoke, antagonize, alienate -- and fascinate rubber-necking onlookers from sea to shining sea. Fixating on race is an absurdity that has no rational reason to exist, yet no one quite knows how to eliminate it from humankind. The only thing dumber than race is underestimating its importance.



Gene Seymour

"Django Unchained" is Tarantino's latest exercise in genre-bending audacity, an antic ripsnorter folding in most of what its director knows and loves about spaghetti westerns, 1970s blaxploitation thrillers and his own ribald, recklessly violent body of work. Its title character, played by Jamie Foxx, is a slave bought and freed by a drolly effective German bounty hunter (Christoph Waltz), who agrees to help Django emancipate his wife, Broomhilda (Kerry Washington), from a decadent plantation owner (Leonardo DiCaprio).



"Django" makes no pretense of being anything other than a phantasmagoric pseudo-western, rife with calculated vulgarity, anachronism and impropriety. Its body count rivals that of Tarantino's 2003 martial-arts epic, "Kill Bill Vol. 1" (to whose messily operatic set pieces of slaughter "Django" bears an uncanny resemblance).


Marquee blog: What's the verdict on "Django Unchanied"?






The movie has so far grossed more than $100 million since its Christmas Day nationwide release. Critics' reactions have ranged from wild-eyed enthusiasm (The Boston Globe's Wesley Morris: "Corkscrewed, inside-out, upside-down, simultaneously clear-eyed and out of its mind") to wary detachment (The Detroit News' Tom Long: "(Y)ou may leave ... wishing for both more and less") to borderline outrage (Slate's Dana Stevens: "There's something about (Tarantino's) directorial delectation in all these acts of racial violence that left me not just physically, but morally queasy.")


Given advance hype for the movie as extravagant as its violence, I doubt that audience members, whatever their race or age, bought tickets with the expectation of seeing some historically faithful saga of antebellum life, and neither did I. We were buying a comic book. Many people have a grievance against the very notion of comic books, but I don't. Expect a movie or a comic book to explain everything about anything and all you earn is surplus sadness that you don't really need.


Nevertheless, there are many who, unlike Lee, have seen the movie and carry the same grievances as he does. The most scathing attack came from that novelist-satirist-poet Ishmael Reed, writing in The Wall Street Journal: "To compare this movie to a spaghetti western and a blaxploitation film is an insult to both genres. It's a Tarantino home movie with all the racist licks of his other movies." He aimed this laser shot at the Oscar-nominated actor who plays the treacherous "house slave" to DiCaprio's character: "Samuel L. Jackson ... plays himself."


I doubt Jackson felt the blow. He has, in fact, further provoked the movie's antagonists by running straight at an interviewer asking about the movie's prolific use of the "N-word," refusing to answer the question unless the reporter, who is white, actually says the dread epithet aloud. (He didn't.)


Still, Reed's condemnation discloses what may lie at the heart of Lee's objection: the debate over whether white artists have the right to tell any part of the black American story -- which, as Reed writes, is as old as Harriet Beecher Stowe's 1852 abolitionist novel, "Uncle Tom's Cabin."


It is also as recent as 1967 when the white Southern novelist William Styron published, "The Confessions of Nat Turner," a Pulitzer Prize-winning novel told in the first-person voice of the brilliant-but-doomed leader of an 1838 slave rebellion. The outcry from African-American novelists was so intense that a collection of essays, "William Styron's Nat Turner: Ten Black Writers Respond" was published a year later. James Baldwin, a friend of Styron's who was one of the few African-American authors speaking out on the book's behalf, put his position as succinctly as possible: "I will not tell another writer what to write. If you don't like their alternative, write yours."


It's still sound advice -- and in the intervening years, black authors have taken it, from Alex Haley's 1976 blockbuster, "Roots," to Toni Morrison's haunting "Beloved" from 1987. Both were adapted for the screen, and while "Roots," the television miniseries, delivered a resounding national impact, the 1998 movie adaptation of "Beloved," even with Oprah Winfrey as producer and co-star, earned about $26 million, roughly half of its $50 million budget.


I remember many of my African-American relatives and friends who told me they were not going to see "Beloved," no matter how good it was or who was in it, because they simply did not want to watch a movie about slavery's legacy. Some of these same folks, on the other hand, tell me they were psyched about seeing a movie, however "incorrect" on several levels, in which a black ex-slave secures freedom for his wife, kills every white man who stands in his way -- and gets away with it.


Exasperated? If you're not, you should be.

USADA head: I got death threats during Armstrong probe

(CBS News) Travis Tygart is the head of the U.S. Anti-Doping Agency, which polices U.S. Olympic sports. Lance Armstrong won the world's most grueling event, the Tour de France, seven times. But after Tygart's investigation, Armstrong lost all of his titles. In his first interview, Tygart spoke with us for the premier of a new program, "60 Minutes Sports" on Showtime. Tygart says Armstrong was doping in his very first win at the Tour de France in 1999. The drug was EPO, which boosts endurance.

TRAVIS TYGART: Six samples that were taken from Lance Armstrong were retested in '05. And they were positive.

SCOTT PELLEY: In '99, when the tests were originally taken, was it reported that they were negative?

TYGART: There was no test for EPO. They were not tested for EPO at that time.

PELLEY: And when you tested for them in 2005, you discovered that they were --

TYGART: All six were flaming positive.

PELLEY: Flaming positive?

TYGART: Flaming positive.

Armstrong allegedly offered large "donation" to doping agency
Atty. denies report Lance Armstrong will admit doping
Lance Armstrong sued for more than $1.5M by U.K. newspaper over libel case

Tygart told Pelley that throughout the investigation, witnesses were intimidated to try to keep the code of silence from breaking.

PELLEY: Was Lance Armstrong personally involved in intimidating these other riders to keep them quiet?

TYGART: He was. It was tough. All -- all these witnesses were -- were scared of the repercussions of them simply telling the truth.

PELLEY: What could Lance Armstrong do to them?

TYGART: Incinerate them.

Former teammate Levi Leipheimer felt the heat. In his sworn affidavit, he says he came to a cycling dinner after he testified to the grand jury. Leipheimer says Armstrong was there and sent Leipheimer's wife a text that read, "Run don't walk."

PELLEY: What did she take it to mean?

TYGART: It's a veiled threat. Knowing her husband had just testified, truthfully, in front of the grand jury and had told citizens of this country about this great fraud. It was a message: You better run.

PELLEY: Your investigation showed that there were personal threats made against riders who had decided to come clean. I wonder if there were any threats against you.

TYGART: There were, Scott.

PELLEY: These threats came from where?

TYGART: Emails, letters.

PELLEY: Anonymous?

TYGART: Yeah.

PELLEY: Can you remember any of the lines from the emails or the letters?

TYGART: The worst was probably putting a bullet in my head.

PELLEY: Did you take that seriously?

TYGART: Absolutely.

To hear the rest of Travis Tygart's story, tune into the premiere edition of "60 Minutes Sports" tomorrow at 10:00 p.m. on the Showtime Network.

Menu Calorie Counts: How Accurate Are They?













They are supposed to help America's obesity problem: calorie counts boldly displayed on restaurant menus across the country and important information, considering Americans now eat one-third of their meals outside the home.


Two states and nine counties require them today, and by the middle of next year, a federal law is expected to force chain restaurants, convenience stores and vending machines nationwide to post calorie counts.


But how accurate are those numbers that so affect your waistline?


A 2011 study by Tufts University sampling food from 42 restaurants says it depends.


Fast food restaurants were the most accurate because of the uniform recipes and portions, but there were wide variations found in sit-down restaurants.


"We found that 20 percent of the foods we tested had 100 calories or more over what was stated on the menu," Lorien Urban, a postdoctoral associate in the energy metabolism lab at Tufts University and first author of the study, told ABC News. "We would consider that to be a considerable amount."


Urban explained that consuming an extra 100 calories per day can lead to an extra 10 pounds in one year.


Most concerning was that a majority of the errors Urban and her colleagues found were made on the diet side of the menu.








Calorie Check: How Many Servings Are You Eating? Watch Video









"These were the foods that people who are trying to manage their weight would gravitate towards and they may be getting more calories than they expect," she said.


ABC News sent producers in three cities that already require posting menu calories to major chains to do a sampling under the direction of a nationally known lab and found that more than half of the low-cal meals tested had more calories than listed on the menu.


In total 24 food samples from four sit-down restaurants and one McDonald's were collected and the results were surprising.


McDonald's did the best. Its Big Mac Meal (posted: 930) and its Premium Chicken Sandwich (posted: 400) tested 30 calories below the menu posting.


But the sit-down restaurants had results sometimes wildly different than advertised.


In all, only one calorie count was accurate -- a Skinnylicious chicken salad sandwich from the Cheesecake Factory.


Eleven meals had more calories than on the menu and 10 had fewer calories. Some were over by only 40 calories; another was over by as much as 420 calories, again at the Cheesecake Factory: This time an order of the fish and chips dinner.


Urban said that fast food restaurants tended to be more accurate than sit-down because of the formulaic preparation that fast food restaurants use.


"Things are arriving already packaged into the restaurants and it's just a matter of warming it up and serving it to the consumer," she said. "A sit-down restaurant, things are being prepared on [the] spot [and] by chance some extra butter gets into the pan."


That can change the calorie amount.


All the restaurants and their trade association say that most calorie counts are as accurate as possible and tested extensively to make sure.


They conceded that there are variations, mostly due to portion size and individual restaurant preparation, and that the menus warn actual calories may vary.


What can you do? Take control of what is put on top of the entree by asking for everything fattening -- such as cheeses, sauces or dressings -- on the side.

World's oldest pills treated sore eyes








































In ancient Rome, physicians treated sore eyes with the same active ingredients as today. So suggests an analysis of pills found on the Relitto del Pozzino, a cargo ship wrecked off the Italian coast in around 140 BC.













"To our knowledge, these are the oldest medical tablets ever analysed," says Erika Ribechini of the University of Pisa in Italy, head of a team analysing the relics. She thinks the disc-shaped tablets, 4 centimetres across and a centimetre thick, were likely dipped in water and dabbed directly on the eyes.












The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite, echoing the widespread use of zinc-based minerals in today's eye and skin medications. Ribechini says there is evidence that Pliny the Elder, the Roman physician, prescribed zinc compounds for these uses almost 250 years after the shipwreck in his seminal medical encyclopaedia, Naturalis Historia.












The tablets were also rich in plant and animal oils. Pollen grains from an olive tree suggest that olive oil was a key ingredient, just like it is today in many medical and beauty creams, says Ribechini.












The tablets were discovered in a sealed tin cylinder called a pyxis (see image above). The tin must have been airtight to protect its contents from oxygen corrosion.












"Findings of such ancient medicines are extremely rare, so preservation of the Pozzino tablets is a very lucky case," says Ribechini.












The cargo of the wreck, discovered in 1989, is rich in other medical equipment, including vials and special vessels for bloodletting. This suggests that one of the passengers may have been a physician.

"17 billion" Earth-sized planets in Milky Way: study






WASHINGTON: The Milky Way contains at least 17 billion planets the size of Earth, and likely many more, according to a study out Monday that raises the chances of discovering a sister planet to ours.

Astronomers using NASA's Kepler spacecraft found that about 17 per cent of stars in our galaxy have a planet about the size of Earth in a close orbit.

The Milky Way is known to host about 100 billion stars, meaning that about one of every six has an Earth-sized planet around it.

The finding does not mean that all those planets beyond our solar system, or exoplanets, could be habitable, though it increases the chances of finding planets similar to Earth.

In order to host life, and allow water to flow in liquid form, a planet must be at a distance from its star that allows surface temperatures to be neither too hot nor too cold.

The Kepler craft detected possible exoplanets when they passed in front of their star, creating a mini-eclipse that dims the star slightly.

During the first 16 months of the survey, Kepler identified about 2,400 candidates.

Francois Fressin, of the Harvard-Smithsonian Center for Astrophysics, and his colleagues used the results to determine which signals were true and to list the exoplanets by size.

They found that 17 percent of stars have a planet 0.8 to 1.25 times the size of Earth in an orbit of 85 days or less.

About a fourth of stars have a super Earth (1.25 to twice the size of Earth) in an orbit of 150 days or less, with a same fraction having a mini Neptune (two to four times Earth) in orbits up to 250 days long.

Larger planets are a much rarer occurrence. Only about three percent of stars have a large Neptune (four to six times Earth) and only five percent have a gas giant (six to 22 times Earth) in an orbit of 400 days or less.

The researchers presented the analysis at a meeting of the American Astronomical Society in Long Beach, California.

Separately, NASA's Kepler mission announced it had discovered 461 new possible planets.

Four of them are less than twice the size of Earth and orbit their sun's "habitable zone," where liquid water might exist on the planet's surface and thus make life possible.

The findings, based on observations conducted from May 2009 to March 2011, showed the number of smaller-size planet candidates and the number of stars with more than one candidate steadily rising.
