China takes steps to clean up 'cancer villages'

The Chinese government has acknowledged the existence of "cancer villages": areas where rates of cancer are unusually high, probably because of industrial and agricultural contamination of drinking and irrigation water.

The reference to the cancer clusters was in China's first ever five-year plan for environmental management of chemicals, released on 20 February. The Chinese media, translating parts of the report, said it links water pollution to "serious cases of health and social problems like the emergence of cancer villages in individual regions".

The term has caught on over the past few years as the media in China and elsewhere reported on apparent cancer hotspots. It gained prominence in 2009 when a journalist plotted 40 of them on a Google Map. Some reports have suggested there might be more than 450 such clusters.

According to recent data, deaths from cancer in China increased by 80 per cent between 1970 and 2004. The disease now accounts for 25 per cent of deaths in cities and 21 per cent in rural areas. However, people in China have an 18.9 per cent risk of getting cancer before the age of 75, compared with 29.9 per cent for people in the US and 26.3 per cent in the UK.

One "typical cancer village", as it was called by researchers from Dezhou University in Shandong province who studied it in 2008, had between 80 and 100 deaths from cancer over five years in a population of only 1200.

But proving a link between pollution and cancer requires more detailed evidence, says Tim Driscoll, an epidemiologist at the University of Sydney and science adviser to Cancer Council Australia. However, Driscoll also says it doesn't really matter – if there is dangerous pollution anywhere, it should be cleaned up.

And that is the plan. China's Ministry for Environmental Protection has drawn up a list of 58 chemicals that will be tracked with a registry, including known and suspected carcinogens and endocrine disrupters. Before the end of the 2015, they will subdivide the list into chemicals to be eliminated and those to be reduced.

Big shift

Creating a plan to eliminate some chemicals is a big shift, says Yixiu Wu, a Greenpeace East Asia campaigner based in Beijing, who says even committing to controlling these chemicals would have been a step forward.

The ministry's acknowledgement of the problem is "really important and it is another reflection of the government's shift towards more transparency in pollution information," says Sabrina Orlins from the Institute of Public and Environmental Affairs, a non-profit body in Beijing.

"Increased environmental information leads to increased public awareness where people can have the chance to exert pressure on big water polluters to adopt clean-up measures and be more accountable," she says.

That accountability is where the five-year plan is lacking, says Wu. "It is still a question whether the government is willing to release all the information about the factory locations and their environmental risk," she says. "It is very important for people who are living nearby."

Wu says the motivation to develop the plan comes from an increasing awareness of the human cost of pollution as well as the country signing up to several international conventions designed to curb pollution.

Mobile makers set sights on grandparents

BARCELONA: As smartphone giants Apple and Samsung battle for the wallets of tech-savvy youngsters, a growing number of manufacturers is trying to lure a fast-growing new market: their grandparents.

Handset makers at the world's biggest mobile fair in Barcelona, Spain, showed off a slew of new devices aimed at the hundreds of millions of older people put off by the complexity of the latest iPhones and Android-powered smartphones.

One of the leaders of the segment in Europe, Austrian firm Emporia, launched a new handset, the Emporia Connect, at the February 24-28 Mobile World Congress.

The sleek-looking black and silver flip phone is designed not to be "stigmatising" yet easy enough for older buyers to use, said Emporia's general manager for France, Christophe Yerolymos.

It has a keypad with larger numbers and an emergency button that will send an SOS along with data pinpointing the location of the phone.

The phone features a system called Emporia Me, with an array of remote control features for the owner's family, allowing a child or grandchild to check the device's location, battery status, or ensure the volume is up.

While it is not a smartphone and has no mapping service, it does have an orientation feature that lets a user push a single button to get turn-by-turn audible instructions for returning to a car while on a shopping trip, for example.

"Emporia is a company in growth, strong growth, even in the heart of the economic crisis we're in at the moment in Europe," said Yerolymos.

Japan's Fujitsu rolled out a European version of a smart phone for seniors, the Stylistic S01, which first launched in mid-2012 in Japan where it lured buyers from a wider age range than the group anticipated, from 45 years upwards.

It is an Android-based smartphone with large, simplified icons, and a "family alert" button that will send a message along with geo-localisation data.

But it also has an unusual touch-screen that will only respond when the user presses a bit harder so as to avoid launching applications by mistake, said Fujitsu Europe-Middle East-Africa product marketing director James Maynard.

"You can actually pre-touch and then when you know which button you want to press, you can exert a little bit more pressure," he said.

"It's made to grow with you so as you become more confident you naturally will exert more pressure on to the device. It's a stepping stone from a feature phone to a smartphone and using a touch panel for the first time."

Kapsys, a French firm, showed off its SmartConnect handset aimed at seniors.

The firm is in discussions with operators including Orange and is hoping to launch the device for about 400 euros (US$520) in Europe in June and then in the United States by the end of 2013, said chief executive Aram Hekimian.

The SmartConnect boasts familiar features for the market: large icons, text in large characters, remote access for family members and also an SOS button with geo-localisation.

But it also incorporates a digital magnifier, enabling the user to roll the phone over text to facilitate reading, for example. The phone is rich in voice command functions, too, allowing the user to avoid fiddly buttons.

"Seniors today are used to having access to technology. As they get older they will want access to the same functions, the same technologies," Hekimian said.

Kapsys estimated the potential market for the telephone at 600 million people, he said. "Our goal is to capture one percent of that market by 2015."

Tablet Tuesday: Get a 10-inch Acer Iconia for $199.99 shipped

At just $199.99, the Acer Iconia Tab A210 offers considerable bang for the buck.

(Credit:
Acer)

Looking for a big tablet? The iPad famously (or infamously) starts at $499. The
Google Nexus 10: $399. Even the comparatively affordable Kindle Fire 8.9 will set you back $299.

For a limited time, and while supplies last, Acer (via Ebay) is selling the refurbished Iconia Tab A210 10.1-inch Android tablet for $199.99 shipped. Deal? More like steal.

The Iconia A210 features a 1.2GHz Tegra 3 processor, 16GB of storage (expandable via microSD cards), the aforementioned 10.1-inch screen (running at a competitive, if not spectacular, 1,280 x 800), and
Android 4.0. Acer will push out an Android 4.1 (Jelly Bean) update in the (presumably) not-too-distant future.

The
tablet weighs 1.5 pounds, so it's a bit on the heavy side, and it has only a front-facing camera. It also lacks an HDMI output, an issue only if you like to wire your tablet to a TV.

CNET hasn't reviewed this model, but over at Amazon (where it sells for $349.99), two dozen buyers collectively rated it 4.5 stars out of 5. Most of the reviews are positively gushing.

Because it's a refurb, you get only a 90-day warranty. If you can live with that, you stand to save a full $150 on this big beauty. Who's in?

While you're mulling that over, take my new poll: How do you use your tablet?

Bonus deal: Game time! Newegg has a BioShock/Elder Scrolls: Oblivion (PC) bundle for free after a $10 mail-in rebate (PDF). Also available: Star Wars: The Force Unleashed 2 (PC) for free after rebate (PDF).

Sharks Warn Off Predators By Wielding Light Sabers

Diminutive deep-sea sharks illuminate spines on their backs like light sabers to warn potential predators that they could get a sharp mouthful, a new study suggests.

Paradoxically, the sharks seem to produce light both to hide and to be conspicuous—a first in the world of glowing sharks. (See photos of other sea creatures that glow.)

"Three years ago we showed that velvet belly lanternsharks [(Etmopterus spinax)] are using counter-illumination," said lead study author Julien Claes, a biologist from Belgium's Catholic University of Louvain, by email.

In counter-illumination, the lanternsharks, like many deep-sea animals, light up their undersides in order to disguise their silhouette when seen from below. Brighter bellies blend in with the light filtering down from the surface. (Related: "Glowing Pygmy Shark Lights Up to Fade Away.")

Fishing the 2-foot-long (60-centimeter-long) lanternsharks up from Norwegian fjords and placing them in darkened aquarium tanks, the researchers noticed that not only do the sharks' bellies glow, but they also had glowing regions on their backs.

The sharks have two rows of light-emitting cells, called photophores, on either side of a fearsome spine on the front edges of their two dorsal fins.

Study co-author Jérôme Mallefet explained how handling the sharks and encountering their aggressive behavior hinted at the role these radiant spines play.

"Sometimes they flip around and try to hit you with their spines," said Mallefet, also from Belgium's Catholic University of Louvain. "So we thought maybe they are showing their weapon in the dark depths."

To investigate this idea, the authors analyzed the structure of the lanternshark spines and found that they were more translucent than other shark spines.

This allowed the spines to transmit around 10 percent of the light from the glowing photophores, the study said.

For Predators' Eyes Only

Based on the eyesight of various deep-sea animals, the researchers estimated that the sharks' glowing spines were visible from several meters away to predators that include harbor seals (Phoca vitulina), harbor porpoises (Phocoena phocoena), and blackmouth catsharks (Galeus melastomus).

"The spine-associated bioluminescence has all the characteristics to play the right role as a warning sign," said Mallefet.

"It's a magnificent way to say 'hello, here I am, but beware I have spines,'" he added.

But these luminous warning signals wouldn't impede the sharks' pursuit of their favorite prey, Mueller's bristle-mouth fish (Maurolicus muelleri), the study suggested. These fish have poorer vision than the sharks' predators and may only spot the sharks' dorsal illuminations at much closer range.

For now, it remains a mystery how the sharks create and control the lights on their backs. The glowing dorsal fins could respond to the same hormones that control the belly lights, suggested Mallefet, but other factors may also be involved.

"MacGyver" of Bioluminescence

Several other species use bioluminescence as a warning signal, including marine snails (Hinea brasiliana), glowworms (Lampyris noctiluca) and millipedes (Motyxia spp.).

Edith Widder, a marinebiologist from the Ocean Research and Conservation Association who was not involved in the current study, previously discovered a jellyfish whose bioluminescence rubs off on attackers that get too close.

"It's like paint packages in money bags at banks," she explained.

"Any animal that was foolish enough to go after it," she added "gets smeared all over with glowing particles that make it easy prey for its predators."

Widder also points out that glowing deep-sea animals often put their abilities to diverse uses. (Watch: "Why Deep-Sea Creatures Glow.")

"There are many examples of animals using bioluminescence for a whole range of different functions," she said.

Mallefet agrees, joking that these sharks are the "MacGyver of bioluminescence."

"Just give light to this shark species and it will use it in any possible way."

And while Widder doesn't discount the warning signal theory, "another possibility would be that it could be to attract a mate."

Lead author Julien Claes added by email, "I also discovered during my PhD thesis that velvet belly lanternsharks have glowing organs on their sexual parts."

And that, he admits, "makes it very easy, even for a human, to distinguish male and female of this species in the dark!"

The glowing shark study appeared online in the February 21 edition of Scientific Reports.

First Lady Sees 'Movement' in Childhood Obesity

As she celebrates the third anniversary of her Let's Move! initiative, first lady Michelle Obama told "Good Morning America" co-anchor Robin Roberts that the country is seeing real "movement" on the issue of childhood obesity.

"We've really changed the conversation in this country. When we started, there were a lot of people in this country who would have never thought that childhood obesity was a health crisis. But now we're starting to see some movement on this issue," the first lady told Roberts. "Our kids are eating better at school. They're moving more. And we're starting…to see a change in the trends. We're starting to see rates of obesity coming down like never before."

"What we're seeing is that there's hope, and when a nation comes together, and everyone is thinking about this issue and trying to figure out what role they can play, then we can see changes," she said.

Mrs. Obama is set to embark on a star studded national tour this week to promote and celebrate her Let's Move! initiative. Her first stop will be in Clinton, Miss. on Wednesday when she appears at an event highlighting healthy school lunches with Rachael Ray.

"I'm going back to Mississippi because when I first went there, Mississippi was considered one of the most unhealthy states in the nation," Mrs. Obama said.

"If we could fry water in Mississippi, we would, we would do that," Roberts, who grew up in Pass Christian, Mississippi, said. "Food is a culture."

"But the good news in Mississippi is that they've seen a decline in childhood obesity of 13 percent, so we're gonna go celebrate and highlight what has been going on there. There's still work to do," the first lady said.

On Thursday, the first lady will travel to her hometown of Chicago, where she will be joined by Olympic gymnasts and tennis star Serena Williams to promote more physical activity in schools. Later in the day, Mrs. Obama will discuss healthy food choices at a Wal-Mart store in Springfield, Mo.

Mrs. Obama said she will announce a new initiative called the "My Plate Recipe Partnership," which will provide families with online access to healthy recipes that meet the My Plate guidelines, the U.S. Department of Agriculture's replacement of the food pyramid.

"More and more chefs, more and more food companies are understanding that they have to find ways to help families do this in a way that's gonna taste good, that kids are gonna like it," she said.

The first lady, Roberts and Chef Marcus Robert Samuelsson, who owns Red Rooster Harlem in New York City, cooked a healthy meal of beef stir fry and broccolini together on the "Good Morning America" set. Mrs. Obama admitted "it's been a while" since she's cooked for her family, but said she looks forward to the day she can whip up meals for her husband and daughters.

"I walk in the kitchen every day, every day," she joked.

But cooking for her family isn't the only thing Mrs. Obama said she misses since becoming first lady.

"Going to Target for me is like a dream, you know? That one time I went, you noticed it created a stir. I'm gonna do it again, doggone it. Next four years, I'm going out. I'm breaking out. I'm gonna disguise Bo. I'm gonna put on a coat. I'm gonna take a walk, and my agents won't know a thing. Don't tell 'em," she joked.

Armband adds a twitch to gesture control

And you thought depth-sensing cameras were cool: well, now there's a gesture control device that looks like a sweatband. It lets you control everything from computers to flying drones just by moving the muscles in your forearm.

The Myo, built by Canadian startup firm Thalmic Labs, based in Kitchener, Ontario, aims to bring gestural interfaces right into the mainstream. Electrodes embedded in the band read electrical activity in a user's muscles as they contract or relax to make gestures with their hand and arm, and transmit it wirelessly to software that interprets the movements into commands.

"We really have this belief that technology can be used to enhance our abilities," says Stephen Lake, co-founder of Thalmic Labs. "This is a way of using natural actions that we've evolved to intuitively control the digital world."

Lake and his team built Myo using electrodes that work without making direct contact with the skin, unlike medical electrodes. The first generation can recognise around 20 gestures, some as subtle as the tap of a finger – and it is programmed to ignore random noise generated by other body movements.

Myo's creators envision it as an easy way to interact with everything from web browsers to video games to small drones. The first generation of the product, is expected to cost $149 and ship later this year. It will come with software that will allow any Windows or Apple Mac machine to recognise the gestures we use on touchscreens – like a vertical swipe to scroll down a page, or a pinch to zoom.

"It's not very often that a new, affordable and convenient interface technology comes along, so I think a lot of programmers are going to want to try it," says Trevor Blackwell, founder of robotics company Umbrella Research and a partner in Y Combinator. This startup incubator programme is based in Mountain View, California and has provided Thalmic Labs with funding in exchange for a 7 per cent stake in the company. "I think so far we've only thought of around 1 per cent of its potential applications."

Thalmic Labs is not the first firm to try making a device that recognises gestures by sensing muscle activity. In 2008, Microsoft created a prototype called MUCI that worked in a similar fashion to Myo, but needed medical electrodes, which are not feasible outside of a laboratory setting.

There are also devices that use cameras to precisely track users' hand motions, but they are either in early stages of development, or not portable. "Maybe this couldn't have been foreseen by early researchers working with cameras, but people don't like having cameras watching them all the time," Blackwell says. "Thalmic solves that problem nicely." Though the first generation of Myo is only just launching, the team is already imagining ways to integrate their rigs with augmented reality devices like the head-mounted display, Google Glass.

"If they combined with Google's Project Glass, I think it would be huge," says computer scientist Shahzad Malik, who co-founded the software company CognoVision of Toronto. "Something like Thalmic's technology is super-useful since you can do interactions in a subtle way, which is important when you're in a public venue."

"We're interested in seeing just how closely we can integrate technology into our daily lives and give people superpowers, if you like," says Lake.

Wear tech... look great?

Making wearable technology fashionable is tough – think belt-mounted cellphones, beepers, and bluetooth ear pieces. But iPod earbuds and headphones seem to work.

How do you get the mix right? Google is working hard to make Project Glass rigs look hip, even convincing clothing designer Diane von Fürstenberg and her models to wear prototypes of the head-mounted displays at Fashion Week in New York last year.

Myo bands (see main story) could be an easier sell , says computer scientist Shahzad Malik. "I could see these bands becoming smaller and smaller, or are made in different colours. Or there could be clothing with it built in," he says.

Syria opposition threat clouds first Kerry overseas tour

LONDON: New US Secretary of State John Kerry met British Prime Minister David Cameron on Monday at the start of a get-acquainted tour of Europe and the Middle East, but the Syrian conflict threatened to taint the trip.

US officials were trying to persuade the Syrian opposition to reconsider its threat to boycott an international meeting in Rome on Thursday, which was to be the centrepiece of Kerry's first overseas tour since he took over from Hillary Clinton.

The Syrian National Council has said it will pull out of the 11-nation Friends of Syria talks in protest at the international community's inability to halt the bloodshed.

Kerry is due to meet his Russian counterpart Sergei Lavrov in Berlin on Tuesday and is expected to push Moscow to put pressure on the Syrian regime to allow a "political transition".

Lavrov held talks in Moscow on Monday with President Bashar al-Assad's foreign minister, who said the Syrian regime was ready for talks with the rebels and anyone who favours dialogue, in the first such offer by a top Syrian official.

Russia is one of the few major powers who still maintain ties with Assad's regime.

A senior US official said on Sunday: "We feel that Russia can play a key role in convincing the (Syrian) regime that there is need for political transition."

Kerry, a former US presidential candidate, made a gentle start to his marathon tour of close US allies by enjoying a traditional English breakfast with Cameron at Downing Street on Monday.

The two men discussed Syria and also talked of how to achieve a trade deal between the United States and the European Union.

They agreed that the G8 summit in Northern Ireland in June "will be an important moment to inject further momentum into this", according to a statement from Cameron's office.

Kerry then went into talks with British Foreign Secretary William Hague which will be followed by a joint news conference later before Kerry heads to the German capital.

The trip will also include stops in France, Italy, Turkey, Egypt, Saudi Arabia, the United Arab Emirates and Qatar.

Kerry is also expected to address issues including Iran, Mali and North Korea during the two-week tour.

US officials were privately optimistic that they could persuade the Syrian opposition to attend the talks on Thursday.

Publicly, a State Department official said: "We are stressing... that they (the opposition) have an opportunity in Rome, to see the countries that have been their greatest supporters and to present to all of us how they see the situation on the ground in security, humanitarian, political and economic terms.

"This meeting is also an opportunity for them to meet our new secretary of state and to speak directly to him," he added.

Syria will also dominate Kerry's talks in Ankara and Cairo, where he is due to meet with the Secretary General of the Arab League, Nabil al-Arabi.

The Kerry-Lavrov meeting on Tuesday will take place at the same time as talks in Kazakhstan between the so-called 5+1 world powers -- US, China, Russia, France, Britain and Germany -- and Iran over the issue of Tehran's nuclear policy.

A US official said strengthened sanctions were having a "real effect" in Iran and welcomed the "common" position among the group.

The trip sees Kerry, the son of a diplomat, back on familiar ground. He spent part of his childhood in Berlin and has family in France.

India is now the latest country to get BlackBerry's Z10 handset.

The company today announced that it has launched the smartphone in India for 43,490 rupees ($800). The device is already available in the U.K. and Canada.

According to BlackBerry, the handset will be offered in over 2,000 retail locations across 50 cities around India. The handset will support carriers running 3G or HSPA+ networks, and the handsets will fully support global roaming.

BlackBerry is taking its time offering its new line of handsets around the world: The U.S. is expected to get the Z10 towards the middle of next month. However, when it launches in the States, it won't come with the massive unsubsidized price tag that Indian consumers will confront, since carriers here will subsidize the price.

Picture Archive: Dorothy Lamour and Jiggs, Circa 1938

Dorothy Lamour, most famous for her Road to ... series of movies with Bing Crosby and Bob Hope, never won an Oscar. In her 50-plus-year career as an actress, she never even got nominated.

Neither did Jiggs the chimpanzee, pictured here with Lamour on the set of Her Jungle Love in a photo published in the 1938 National Geographic story "Monkey Folk."

No animal has ever been nominated for an Oscar. According to Academy Award rules, only actors and actresses are eligible.

Uggie, the Jack Russell terrier from last year's best picture winner, The Artist, didn't rate a nod. The equines that portrayed Seabiscuit and War Horse, movies that were best picture contenders in their respective years, were also snubbed.

Even the seven piglets that played Babe, the eponymous star of the best picture nominee in 1998, didn't rate. And the outlook seems to be worsening for the animal kingdom's odds of ever getting its paws on that golden statuette.

This year, two movies nominated in the best picture category had creatures that were storyline drivers with significant on-screen time. Neither Beasts of the Southern Wild (which featured extinct aurochs) or Life of Pi (which featured a CGI Bengal tiger named Richard Parker) used real animals.

An Oscar's not the only way for animals to get ahead, though. Two years after this photo was published, the American Humane Association's Los Angeles Film & TV Unit was established to monitor and protect animals working on show business sets. The group's creation was spurred by the death of a horse during the filming of 1939's Jessie James.

Today, it's still the only organization that stamps "No Animals Were Harmed" onto a movie's closing credits.

Editor's note: This is part of a series of pieces that looks at the news through the lens of the National Geographic photo archives.

Best Moments From the Academy Awards

Host Seth MacFarlane took the stage at the 2013 Oscars with an opening monologue revealing he was ready to poke fun at the star-studded audience.

"The quest to make Tommy Lee Jones laugh begins now," he said.

But it wasn't too long before MacFarlane was interrupted. William Shatner, dressed as his iconic character Captain Kirk from "Star Trek," descended on the stage to warn MacFarlane that he was about to ruin the Oscars and be branded the worst host ever.

"The show is a disaster. I've come back in time … to stop you from ruining the Academy Awards," Shatner said.

Seth MacFarlane's Boobs Tribute

Shatner tried to steer MacFarlane away from singing an "incredibly offensive song that upsets a lot of women in the audience."

Cue MacFarlane's medley "We Saw Your Boobs," a laundry list set to music of acclaimed actresses in Hollywood who all bared their breasts in film.

MacFarlane was joined by the Gay Men's Chorus of Los Angeles to call out Meryl Streep, Anne Hathaway, Naomi Watts, Jodie Foster, Hilary Swank and countless others who we've seen nude in film.

Not every joke funnyman Seth MacFarlane made landed with the A-list crowd at the 85th annual Academy Awards.

The host elicited gasps from the crowd when he introduced "Django Unchained" as "the story of a man fighting to get back his woman, who's been subjected to unthinkable violence. Or, as Chris Brown and Rihanna call it, a date movie."

Another joke that somehow earned a too-soon nod? A throw to President Abraham Lincoln's assassination.

"I'd argue that the actor who really got inside Lincoln's head was John Wilkes Booth," MacFarlane said.

MacFarlane's jab at Mel Gibson didn't land too smoothly either. MacFarlane said the N-word laden "Django Unchained" screenplay was "loosely based on Mel Gibson's voicemails."

Oscars' Movie Musical Tribute

The theme of the 85 annual Academy Awards was celebrating music in film, and the tributes to movie musicals didn't disappoint.

Featured performers included Catherine Zeta-Jones belting "All That Jazz" from 2002's Best Picture winner "Chicago," Jennifer Hudson's show-stopping "And I'm Telling You I'm Not Going" from 2006's "Dreamgirls," and the cast of this year's Best Picture nominee "Les Miserables" reuniting on stage for "One Day More."

Introducing the Von Trapp Family

To introduce Christopher Plummer to the stage to present the award for Best Supporting Actress, MacFarlane couldn't help but make a joke out of the actor's infamous role as Captain Von Trapp in "The Sound of Music."

MacFarlane came out to announce the Von Trapp family singers, but no one came out. Instead, a man dressed in a Nazi uniform ran in to tell him that they were gone.

Kristen Stewart Hobbles on Stage to Present

When Daniel Radcliffe took the stage to present the award for Achievement in Production Design, he was joined by his hobbling co-presenter Kristen Stewart, who was seen crutching along the red carpet during the pre-show.

The "Twilight" star's makeup artist told People magazine that the actress "cut the ball of her foot, quite severely, on glass two days ago."

The Associated Press reported that backstage, Best Supporting Actress winner Anne Hathaway told Stewart to "break a leg."

Jennifer Lawrence's Unstable Victory

Jennifer Lawrence was so shocked to take home the Oscar for Best Actress that she lost her footing on her way up to the stage to accept her award.

"You guys are just standing up because I fell and that's really embarrassing," she said to the audience.

Lawrence regained her composure to give her acceptance speech, extending a special thank you to "the women this year," who she called "so magnificent and so inspiring."

Daniel Day-Lewis a Three-Peat Best Actor Winner

It was a highly anticipated win for Daniel Day-Lewis, who took home the award for Best Actor for his portrayal of Abe Lincoln in Steven Spielberg's "Lincoln."

Lewis cracked a joke in his acceptance speech, saying he was supposed to be cast as Margaret Thatcher and presenter Meryl Streep was the first choice for Lincoln.

"Meryl Streep was Steven's first choice to play Lincoln… I'd like to see that version," Lewis said.

Michelle Obama Announces Best Picture Winner

In one of the biggest surprises of the night, the Academy brought out First Lady Michelle Obama to help Jack Nicholson introduce the nominees for Best Picture.

Rocking her new bangs and a silver gown, the first lady, live from the White House, announced "Argo" as this year's Best Picture.

"It was a thrill to announce the #Oscars2013 best picture winner from the @WhiteHouse! Congratulations Argo!" FLOTUS tweeted afterwards.

Ben Affleck Triumphs at Oscars

Ben Affleck was flabbergasted by his win for Best Picture for "Argo." His frenzied, heartfelt acceptance speech resonated as he thanked his wife, Jennifer Garner, and ended on an inspirational high note.

"I want to thank my wife, who I don't normally associate with Iran. I want to thank you for working on our marriage. It is work, but it is the best kind of work," he said.

"I was here 15 years ago or something and you know I had no idea what I was doing. I stood out here in front of you all, really just a kid. I went out and I never thought I'd be back here and I am because of so many of you who are here tonight …. I want to thank them for what they taught me, which is that you have to work harder than you think you possibly can, you can't hold grudges. It's hard, but you can't hold grudges. And it doesn't matter how you get knocked down in life because that's going to happen. All that matters is that you got to get up."
