Interactive Mailbox Project Shares Text-Message Secrets

Hello Lamp Post! is a new public art project that will let you communicate with post boxes and lamp posts without anyone questioning your mental health.

The public installation invites people to tune into secret conversations throughout the city and communicate through street furniture such as lamp posts, bus stops, bins and post boxes. The project will use the codes that city councils and public servants use to tell one object from another when a light bulb in a lamp post needs changing or a bus stop needs to be repaired or rerouted — for example, each post box in Bristol has a six-figure code, while storm drains have 14.

The idea is that people will be able to send a text message to these inanimate objects and watch them come to life. By sending an SMS to a certain phone number containing the word “Hello” + the name of the object + its code, the user will elicit a response from that object in the form of a question. This could be as simple as “where am I?” “What do I look like?” or “What’s the most exciting thing to do around here?” These conversation starters will encourage people to reply to the objects. People’s responses are then stored on an online database and fed back to others who text the same object. So the post box might say to a later texter, “someone once told me that the best place to get a falafel was on X street. Do you agree?”

The project, developed by London-based experience design studio PAN, was chosen from 93 applications as the winner of Bristol’s Playable City Award. It will be installed in Bristol in the summer before being toured internationally.

Ben Barker, co-founder of PAN Studio, told Wired that although the early stages will be pre-programmed, the idea is to keep the story quite slight and let people fill in the narrative themselves. “The biggest challenge is that first step. Once people are aware that they can interact in that way, the hope is that they could start building their own games and experiences.”

“We want to change the perception of a post box from something that might have become almost invisible to you in the street. Once you’ve talked to it you will always remember that conversation when you pass that specific location. We are really excited about that.”

In the studio’s pitch document, PAN explains that players are identified through their phone number (or email address or Twitter handle) so that the platform can acknowledge players who call again, offering new options for more experiences players or repeat callers to the same objects.

Barker says that the team will be engaging with the creative community through workshops to encourage people to set up their own games and treasure hunts using the platform. For example, someone might pick 10 objects in the city and seed each of them with clues to find the next one. There will also be an online platform that will visualize the objects and messages, to allow for non-Bristol residents to interact with the artwork.

The judging panel for the competition — who awarded the £30,000 prize — featured Imogen Heap, Google’s Tom Uglow and Claire Doherty of Situations.

Imogen Heap said of the winning entry: “I love this for its whispers on the street, guardians in dark corners, humanizing our cities’ appendages whose eyes and ears now have a voice. Vessels for an ever-evolving conversation, connecting us together. They were there all along!”

Tom Uglow added: “It points to a future made up of the physical objects already around us, the ‘internet of things’, and the underlying complexity is made simple and easy for people by just using SMS for this project. Poetry and technology combine to create subtle and playful reflections of the world we live in. It filled me with a childish delight.”

The piece will be built over the next few months and will be live in Bristol throughout July and August.

Beyonce lets others do talking on lip-synch drama

LOS ANGELES (Reuters) – Beyonce‘s lips remained sealed on Wednesday over her headline-making rendition of the U.S. national anthem at President Barack Obama‘s inauguration, leaving others to do the talking over whether she lip-synched to a pre-recorded track.

Celebrity magazine Us Weekly quoted a source saying the Grammy-winning artist was disappointed by the controversy she stirred by singing “The Star-Spangled Banner” at Monday’s solemn ceremony using a backing track – and drew a comparison to late Italian opera singer Luciano Pavarotti.

As some of America’s singing stars offered sympathy and understanding, an inaugural official, who declined to be identified, told CNN that Beyonce “did not sing live.”

“Because she didn’t have time to rehearse with the U.S. Marine Band, she decided to use her recording with the Marine Band,” the official told CNN on Wednesday.

The U.S. Marine band said in a statement on Tuesday that no one in the band “is in a position to assess whether it was live or pre-recorded.”

Us Weekly meanwhile quoted a different, also unidentified source, as saying “She did sing, but used a track.”

“She didn’t think there was anything wrong with it,” the source told the celebrity magazine‘s website on Wednesday.

“Pavarotti has done it! It was freezing out, and if she messed up just one note, that would have been the story … Everybody uses these tracks, and the music director advised it,” the Us Weekly source added.

Pavarotti lip-synched his last performance, at the 2006 Winter Olympics in Turin, because of the bitter weather and his failing health, according to orchestra conductor Leone Magiera in a 2008 book. The Italian tenor died in 2007 of pancreatic cancer at age 71.

Beyonce‘s publicist has declined to comment on the furor, but Aretha Franklin and Jennifer Lopez chimed in with their support.

“When I heard the news … that she was pre-recorded I really laughed,” Franklin, 70, who sang live at Obama‘s first inauguration in 2009, told ABC News.

“I thought it was funny because the weather down there was about 46 or 44 degrees and for most singers that is just not good singing weather … she did a beautiful job with the pre-record … next time I’ll probably do the same.”

Lopez told Jon Stewart on “The Daily Show” on Tuesday that many performers resort to using pre-recorded tracks.

“You know, sometimes it happens,” Lopez said. “When you’re in certain stadiums and in certain venues, they do pre-record things because you’re going to have that terrible slapback.”

Beyonce, 31, was giving her first major public performance since giving birth to a baby in January 2012. On Sunday, she had posted on Instagram photo of herself in a recording studio holding the sheet music for “The Star-Spangled Banner.”

She is due to take the spotlight again next month by performing, live, at the February 3 Super Bowl halftime show.

New Mutations Discovered in Melanomas

In a leap forward in understanding the basic science of one of the most lethal cancers, two groups of researchers have found mutations in most melanomas that are unlike any they have seen before in cancer. The changes are in regions that control genes, not in the genes themselves. The mutations are exactly the type caused by exposure to ultraviolet light, indicating they might be among the first DNA changes in a cell’s path to melanoma.

The discoveries, published online Thursday in two papers in the journal Science Express, do not immediately suggest new treatments or ways to prevent melanoma, researchers said. But the findings help explain how melanomas — and, possibly, other cancers — develop and what drives their growth, insights that may be critical to long-term efforts to develop ways to prevent or stop the cancer.

For years, cancer researchers have searched for mutations in genes, but this time, they looked for — and found — mutations in a region that regulates genes. They did it by examining the entire DNA of multiple tumors, studying not just genes but also what has been called the dark matter, the 99 percent of the DNA that includes regions that control genes.

“You could think of this as one glimmer in what has been called cancer’s dark matter,” said Dr. Levi A. Garraway of the Dana-Farber Cancer Institute and the Broad Institute of Harvard and M.I.T.

The complete DNA sequences of 70 malignant melanomas led to the new discovery. A small control region was mutated in 7 out of 10 of the tumors, and also, the investigators found, in liver and bladder cancers. The cancer cells had one of two tiny changes that together were more common than any mutation ever found in the genes of melanoma.

A team led by Rajiv Kumar of the German Cancer Research Center in Heidelberg and Dirk Schadendorf of the University of Essen looked for the mutations in a family whose members tended to get melanoma. Four relatives who developed melanoma had inherited one of them, while four who remained melanoma-free did not have it. They also found the mutation in a 36-year-old member of the family who had not developed melanoma but had had many moles, often a sign of risk in families prone to melanoma.

Their findings indicate that those who inherit the mutations might be born with cells that have taken a first step toward cancer.

The mutations spur cells to make an enzyme, telomerase, that keeps cells immortal by preventing them from gradually losing the ends of their chromosome, the telomeres. When telomeres erode, a cell dies. But the enzyme also has other, poorly understood functions that are thought to keep cancer cells alive, said Robert Weinberg, an M.I.T. researcher who studies telomerase and cancer and was not involved with the research. “The paradigm that it does nothing but extend telomeres is a gross oversimplification,” he said.

Abundant telomerase is so important to cancers that it occurs in 90 percent of them, said Immaculata De Vivo, a Harvard Medical School researcher who studies telomerase and cancer and directs a DNA sequencing program. She, too, was not involved with the research.

The results of the two studies presented in the papers “are like a court of law — it’s the preponderance of the evidence,” she said. “We all knew telomerase was important for cancer, but now we are finding the mechanisms, the machinery.”

Scientists were surprised that the mutations in the dark matter of melanoma tumors were so commonplace. Dr. Garraway and his colleagues had the entire DNA sequences for a collection of melanomas — genes as well as the rest of the DNA including areas that turn genes on and off.

“We said, ‘Let’s just take a look and see if there are any mutations in a regulatory region,” Dr. Garraway said.

At first, they looked at the DNA sequences of 19 tumors. They were amazed to find one or the other of the two mutations in 17 of them. So the researchers decided to look at 51 additional melanomas and a handful of bladder and liver cancers. The mutations popped up again.

“It was really quite striking,” Dr. Garraway said.

But it’s not clear how to reverse the mutations’ cancer-causing effects, Dr. Garraway said. And although people have long wanted to block telomerase production in cancer cells, they have not found a drug to do it.

Still, the findings are highly significant, experts said.

“We have always known that just looking at genes alone would provide a limited number of answers about why cancer develops,” said Elaine Mardis of Washington University, who was not involved with the research. “The brakes or the gas that control the genes that cause cancer are as important as gene mutations,” she said. The new papers, Dr. Mardis added, “show where additional answers may lie.”

DealBook: Choice for S.E.C. Is Ex-Prosecutor, in Signal to Wall St.

2:48 p.m. | Updated President Obama tapped Mary Jo White, a former United States attorney turned white-collar defense lawyer, to be the next chairwoman of the Securities and Exchange Commission.

Mr. Obama announced the nomination at the White House on Thursday afternoon. As part of the event, the White House also renominated Richard Cordray to lead the Consumer Financial Protection Bureau, a role he has held for the last year under a recess appointment.

In its choice of Ms. White and Mr. Cordray, the White House is sending a signal about the importance of holding Wall Street accountable for wrongdoing. Both picks are former prosecutors.

Regulatory chiefs are often market experts or academics. But Ms. White spent nearly a decade as United States attorney in New York, the first woman named to this post. Among her prominent cases, she oversaw the prosecution of the mafia boss John Gotti as well as the people responsible for the 1993 World Trade Center bombing. She is now working the other side, defending Wall Street firms and executives as a partner at Debevoise & Plimpton.

As the attorney general of Ohio, Mr. Cordray made a name for himself suing Wall Street companies in the wake of the financial crisis. He undertook a series of prominent lawsuits against big names in the finance world, including Bank of America and the American International Group.

The White House expects Ms. White, 65, and Mr. Cordray, 53, to draw on their prosecutorial backgrounds while carrying out a broad regulatory agenda under the Dodd-Frank Act. Congress enacted the law, which mandates a regulatory overhaul, in response to the 2008 financial crisis.

Jay Carney, the White House press secretary, said Ms. White has “an incredibly impressive resume” and that her appointment along with the renomination of Mr. Cordray sends an important signal.

“The president believes that appointment and the renomination he’s making today demonstrate the commitment he has to carrying out Wall Street reform, making sure we have the rules of the road that are necessary and that are being enforced in a way” to avoid a crisis like that of 2008, Mr. Carney said.

Another White House official added that Ms. White and Mr. Cordray will “serve in top enforcement roles” in part so that “Wall Street is held accountable and middle-class Americans never again are harmed by the abuses of a few.”

Ms. White will succeed Elisse B. Walter, a longtime S.E.C. official, who took over as chairwoman after Mary L. Schapiro stepped down as the agency’s leader in December. Mr. Cordray joined the consumer bureau in 2011 as its enforcement director.

The nominations could face a mixed reception in Congress. The Senate already declined to confirm Mr. Cordray, with Republicans vowing to block any candidate for the consumer bureau, a new agency created to rein in the financial industry’s excesses. It is unclear whether the White House and Mr. Cordray will face another standoff the second time around.

Mr. Carney argued that there were no substantive objections to Mr. Cordray’s confirmation, only political ones. “He is absolutely the right person for the job,” Mr. Carney said.

Ms. White is expected to receive broader support on Capitol Hill. Senator Charles E. Schumer, a New York Democrat, declared that Ms. White was a “tough-as-nails prosecutor” who “will not shy away from enforcing the laws to ensure that markets operate fairly.”

But she could face questions about her command of arcane financial minutiae. She was a director of the Nasdaq stock market, but has otherwise built her career on the law-and-order side of the securities industry.

People close to the S.E.C. note, however, that her husband, John W. White, is a veteran of the agency. From 2006 through 2008, he was head of the S.E.C.’s division of corporation finance, which oversees public companies’ disclosures and reporting.

Some Democrats also might question her path through the revolving door, in and out of government. While seen as a strong enforcer as a United States attorney, she went on in private practice to defend some of Wall Street’s biggest names, including Kenneth D. Lewis, a former head of Bank of America. She also represented JPMorgan Chase and the board of Morgan Stanley. Last year, the N.F.L. hired her to investigate allegations that the New Orleans Saints carried out a bounty system for hurting opponents.

Consumer advocates generally praised her appointment on Thursday. “Mary Jo White was a tough, smart, no-nonsense, broadly experienced and highly accomplished prosecutor,” said Dennis Kelleher, head of Better Markets, the nonprofit advocacy group. “She knew who the bad guys were, went after them and put them in prison when they broke the law.”

The appointment comes after the departure of Ms. Schapiro, who announced she would step down from the S.E.C. in late 2012. In a four-year tenure, she overhauled the agency after it was blamed for missing the warning signs of the crisis.

Since her exit, Washington and Wall Street have been abuzz with speculation about the next S.E.C. chief. President Obama quickly named Ms. Walter, then a Democratic commissioner at the agency, but her appointment was seen as a short-term solution. It is unclear if she will shift back to the commissioner role if Ms. White is confirmed.

In the wake of Ms. Schapiro’s exit, several other contenders surfaced, including Sallie L. Krawcheck, a longtime Wall Street executive. Richard G. Ketchum, chairman and chief executive of the Financial Industry Regulatory Authority, Wall Street’s internal policing organization, was also briefly mentioned as a long-shot contender.

House approves short-term suspension of debt ceiling

WASHINGTON – House Republicans approved a temporary suspension of the $16.4-trillion ceiling on the nation’s debt Wednesday, allowing the federal government to continue borrowing through spring while Washington shifts to more ambitious budget battles.

Speaker John A. Boehner (R-Ohio) convinced his rebellious majority to go along with the new strategy by promising them the opportunity in the months ahead to extract deep spending cuts to Medicare and other domestic programs.

The approach was a seismic political shift for Republicans who in the past had pressed for simultaneous cuts, which House Democrats dismissed as “irresponsible” and a “gimmick.”

The vote was 285-144, and despite the robust support it would not have passed without Democrats -- 33 Republicans opposed it.

QUIZ: Test your knowledge about the debt limit

“We know with certainty that a debt crisis is coming to America,” said Rep. Paul D. Ryan (R-Wis.), the former vice presidential nominee, who helped lead the debate on the House floor as chairman of the House Budget Committee. “We have a moral obligation to fix that.”

Republicans are preparing an extraordinary fiscal plan, due in April, that would bring federal budgets into balance in 10 years – an austerity measure far more severe than last year's budget from Ryan that slashed the safety net.

After President Obama won modest tax hikes on the wealthy in the year-end "fiscal cliff" deal, Republicans say the next round of savings must come from the spending side of the ledger.

“Whatever new taxes the president is going to get, he got,” Senate Minority Leader Mitch McConnell, the Kentucky Republican, said this week. “We’re now going to focus on the real problem, which is not that we tax too little, but that we spend too much.”

The White House, and Democrats in Congress, disagree and say more tax hikes – especially closing corporate tax loopholes – must be part of the equation. Two deadlines in March will force the issue.

Complete coverage of the 2013 inauguration

“Democrats are eager to contrast our pro-growth, pro-middle class-budget priorities with the House Republicans,” said Sen. Patty Murray (D-Wash.), the chairman of the Senate Budget Committee. She said the GOP budget under Ryan “would end Medicare as we know it, gut investments in jobs and programs middle-class families depend on, and cut taxes for the wealthiest Americans and biggest corporations.”

The vote Wednesday puts the White House and Congress on another collision course in the budget battles that are expected to consume the first months of Obama’s second term.

On March 1, the federal budget faces $1.2 trillion in automatic spending cuts that both sides want to alter. Later, on March 27, Congress will need to approve funding for routine government operations, or risk a shutdown.

By May 18, the debt ceiling would need to be raised again after this suspension expires, though the Treasury Department could take measures to extend borrowing into summer.

Failure to raise the debt limit to cover the nation’s already accrued bills would send the country into a large-scale default – what Obama has compared to dining and dashing out on the bill.

PHOTOS: President Obama’s second inauguration

Democrats in the House complained that Republicans were simply setting up another "fiscal cliff."

“House Republicans continue to play with economic fire,” said Rep. Sander Levin (D-Mich.)

The bill approved Wednesday now goes to the Senate, and the White House has said the president would not oppose it.

Even though conservatives off Capitol Hill remain divided over raising the debt limit, Boehner sweetened the legislation to attract Republican support by attaching a provision that would temporarily withhold the pay of senators or representatives if their chamber fails to produce an annual budget by the mid-April deadline.

The “no budget, no pay” provision was particularly popular with conservatives, and was aimed squarely at Senate Democrats, who have declined to approve a formal budget in recent years.

Coming This Year to Afghanistan: Way More Artillery Strikes

As the U.S. tries to hand over responsibility for the Afghan war to the new Afghan military it’s built, some very old weapons systems are poised to become crucial: the mortar and the howitzer.

The plan for 2013 is for the 66,000 U.S. troops in Afghanistan to draw down to an as-yet-undecided size at an as-yet-undecided pace. Those that remain will take a back seat to Afghans by the spring, as the Afghans plan and execute their own operations, a subtle shift from the “partnered” patrols the U.S. emphasized in 2012. Only the Afghans don’t yet have some of the crucial equipment, particularly fighter aircraft and attack helicopters, to help units that come under fire.

With the Afghans’ relative absence of close air support, “what we must do, then, is bring the surface fire capability to fruition, and that’s the indirect fire, observed indirect fire,” Army Lt. Gen. James L. Terry, the day-to-day commander of the war, told reporters at the Pentagon on Wednesday. Chief among them: the D-30 howitzer, a Russian-built 12 mm gun, and 60 mm mortars.

“So now instead of calling back up into the air, they have those organic capabilities inside those formations,” Terry said.

Pentagon officials cautioned that that doesn’t mean the U.S. air war is going to come to an end in 2013. But it’s on a downward trajectory. According to U.S. Air Force statistics, in 2012, U.S. warplanes fired their weapons 4,095 times, the lowest level recorded since 2009′s pre-surge 4,165 weapons releases. Close air support sorties in total were down to 28,471 last year — higher than in 2009, but still lower than their 2010 and 2011 levels.

But the whole idea is to shift the burden of the war onto the nascent Afghan forces. And with Afghan air power running behind Afghan ground forces, protecting Afghan forces under attack is going to be largely a ground responsibility. Terry praised “Afghan solutions” like the rise of a “mobile strike force, an armored wheeled-based platform” that seven Afghan battalions will use. As of now, it’s unarmed, so its purpose is to help Afghan troops survive an attack rather than repel one, but “potentially we’ll look at if we need to put a gun system on one of those platforms.”

Less clear is what the smaller complement of U.S. troops in Afghanistan in 2013 will do in their forthcoming “security force assistance” formations, of which there will be over 400. Their mission will be to train, advise and assist the Afghans as the Afghan troops plan and execute their own fights. But Terry signaled that U.S. forces won’t just be sitting on their bases and advising headquarters staffs.

“This is not simply about doing less,” Terry said, but rather about giving the “right resources” to the Afghans, at the battalion-level and above, so they can hold territory from insurgents.

“Those [U.S.] organizations are not purely headquarters focused, but they are focused, then, on increasing the capability with the Afghans. It doesn’t mean they won’t be going out on patrol with them, either,” Terry said, adding that “some of this training will obviously have to be done in contact” with insurgents — especially providing some of the “enabling capabilities,” like the air support that only the U.S. can provide for now.

Until the Afghans build up their own air force and air-attack specialties, Afghanistan’s soldiers are about to launch a lot more artillery strikes.

Shia LaBeouf’s “Charlie Countryman” finds love in gritty Romania

Park City, Utah (Reuters) – Shia LaBeouf and Evan Rachel Wood spin a twist on classic fairytales in their new film “The Necessary Death of Charlie Countryman,” a modern day love story that swaps castles in the sky for the underbelly of Romania’s capital, Bucharest.

The film, which premiered at Sundance Film Festival this week, is a dark story of love unfolding between two unlikely people against the backdrop of a violent and crime-filled eastern European city.

Charlie (LaBeouf), an American, finds himself on a journey of self-discovery that takes him to Bucharest, where he meets the mysterious and captivating Gabi (Evan Rachel Wood), and puts his life on the line for love.

“Love is always the easiest answer, but somehow it’s the hardest place to get for some people. I love the contrast of this world, which is filled with violence and hatred and crime, and above all there’s love,” Wood said.

Director Fredrick Bond picked Bucharest because he was looking for a place that has not been captured in film prominently, and would compliment the complex nature of Charlie and Gabi’s story.

“Charlie has to go through quite a tough journey and a very romantic journey, so I needed a city that had an edge,” he said.

Wood, 25, said the connection that Charlie and Gabi feel the moment they meet resonated with her because that is what she felt for her husband, actor Jamie Bell, when they first met at Sundance and started dating in 2005.

“It’s almost this karmic connection, this kindred spirit, this soulmate of some sort, where he looks at her and he immediately falls in love. He’s never said a word to her – that really happens. That’s how I met my husband,” Wood said.

“We fell in love immediately, because it was almost meant to be, it was fate.”

FINDING TRUTH IN LOVE

“Charlie Countryman” is the feature film debut from Swedish director Bond, an award-winning creator of commercials. Bond said he was eager to work with LaBeouf and Wood, calling them the “most talented young actors of their generation.”

“They have such a sense of truthfulness,” Bond said. “It’s a wild, crazy journey, I needed actors who could ground their performances … Evan and Shia are about truth.”

LaBeouf, a former child star who became a box office staple as the lead in the “Transformers” franchise, has been taking on grittier roles more recently, such as a bootlegger in gangster drama “Lawless.”

The 26-year-old actor said he had been drawn to the role of Charlie when he read the script three years ago.

“It spoke honestly to me, it was really original. It had a Zsa Zsa Gabor narrative and it just read like ‘The Graduate’ with a bloody nose,” he said.

Wood, who shot to fame as the troubled young lead of teen drama “Thirteen” in 2003, said she had wanted to work with LaBeouf for a long time.

For the role of Gabi, a complex Romanian cellist who has a penchant for bad boys, Wood had to perfect a Romanian accent without the help of a dialect coach, turning to her surroundings in Bucharest to draw inspirations.

“It’s very stressful because you want to do it justice, and I wanted it to be spot-on because a lot of times, it can be very distracting. You can overdo the accent,” the actress said.

The film co-stars Mads Mikkelsen and Til Schweiger as Romanian mobsters, with British actors Rupert Grint, best known as Ron Weasley in the “Harry Potter” movies, and James Buckley as Charlie’s errant friends.

Bond said the biggest filming challenges were the action-packed fight scenes, especially because LaBeouf did his own stunts.

“Shia wants to do everything for real, so he takes hits for real … which is fantastic, because it gives a reality to it, but you also have only so many takes, you have to be really well prepared to do it,” Bond said.

“Charlie Countryman” may defy the archetype of a traditional love story with its fierce characters in a harsh yet beautiful setting, but LaBeouf and Wood said they hoped audiences would take away messages of honesty in love from the film.

Well: Can You Read the Face of Victory?

Picture a tennis player in the moment he scores a critical point and wins a tournament. Now picture his opponent in the instant he loses the point that narrowly cost him the title. Can you tell one facial expression from the other, the look of defeat from the face of victory?

Try your hand at the images below, of professional tennis players at competitive tournaments. All were included in a new study that suggests that the more intense an emotion, the harder it is to distinguish it in a facial expression.

The researchers found that when overwhelming feelings set in, the subtle cues that convey emotion are lost, and facial expressions tend to blur. The face of joy and celebration often appears no different from the look of grief and devastation. Winning looks like losing. Pain resembles pleasure.

But that is not the case when it comes to body language. In fact, the new study found, people are better able to identify extreme emotions by reading body language than by looking solely at facial expressions. But even though we pick up on cues from the neck down to interpret emotion, we instinctively assume that it is the face that tells us everything, said Hillel Aviezer, a psychologist who carried out the new research with colleagues at Princeton University.

“When emotions run high, the face becomes more malleable: it’s not clear if there’s positivity or negativity going on there,” he said. “People have this illusion that they’re reading all this information in the face. We found that the face is ambiguous in these situations and the body is critical.”

Dr. Aviezer and his colleagues, who published their work in the journal Science, carried out four experiments in which subjects were asked to identify emotions by looking at photographs of people in various situations. In some cases, the subjects were shown facial expressions alone. In others, they looked at body language, either alone or in combination with faces. The researchers chose photographs taken in moments when emotions were running high – as professional tennis players celebrated or agonized, as loved ones grieved at funerals, as needles punctured skin during painful body piercings.

According to classic behavioral theories, facial expressions are universal indicators of mood and emotion. So the more intense a particular emotion, the easier it should be to identify in the face. But the study showed the exact opposite. As emotions peaked in intensity, expressions became distorted, similar to the way cranking up the volume on a stereo makes the music unrecognizable.

“When emotions are extremely high, it’s as if the speakers are blaring and the signal is degraded,” said Dr. Aviezer, who is now at Hebrew University in Jerusalem. “When the volume is that high, it’s hard to tell what song is playing.”

In one experiment, three groups of 15 people were shown photographs of professional tennis players winning and losing points in critical matches. When the subjects were shown the players’ expressions alone — separated from their bodies — they correctly identified their emotion only half of the time, which was no better than chance. When they looked at images of just the body with the face removed — or the body with the face intact — they were far more accurate at identifying emotions. Yet when asked, 80 percent said they were relying on the facial expressions alone. Twenty percent said they were going by body and facial cues together, and not a single one said they were looking only for gestures from the neck down.

Then, the researchers scrambled the photos, mixing faces and bodies together. The upset faces of players were randomly spliced onto the bodies of celebrating players, and vice versa.

When asked to judge the emotions, the subjects answered according to the body language. The facial expression did not seem to matter. If a losing face was spliced onto a celebrating body, the subjects tended to guess victory and jubilation. If they were looking at the face of an exuberant player placed on the body of an anguished player, the subjects guessed defeat and disappointment.

Although they were not aware of it, the subjects were clearly looking at body language, Dr. Aviezer said. Clenched fists, for example, suggested victory and celebration, while open or outstretched hands indicated a player’s disappointment.

In another experiment, the researchers looked at four other emotional “peaks.” For pain, they used the faces of men and women undergoing piercings. Grief was captured in images of mourners at a funeral. For joy, they used images of people on the reality television show “Extreme Makeover: Home Edition,” capturing their impassioned faces at the very moment they were shown their beautiful, brand new homes. And for pleasure, they went with a rather risqué option: images from an erotic Web site that showed faces at the height of orgasm.

Once again, the subjects could not correctly guess the emotions by looking at facial expressions alone. In fact, they were more likely to interpret “positive” faces as being “negative” more than the actual negative ones. When faces showing pleasure were spliced onto the body of someone in pain, for example, the subjects relied on body language and were often unaware that the facial expression was conveying the opposite emotion.

“There’s this point on ‘Extreme Makeover’ where people see their new house for the first time and the camera is on their face, so we have these wonderful photos of their expressions,” Dr. Aviezer said. “At that moment, they look like the most miserable people in the world. For a few seconds, it’s as if they are seeing their house burn down. They don’t look like you would expect.”

The researchers noted that they were not suggesting that facial expressions never indicate specific feelings – only that when the emotion is intense and at its peak, for those first few seconds, the expression is ambiguous. Dr. Aviezer said the facial musculature simply might not be suited for accurately conveying extremely intense feelings – in part because in the real world, so much of that is conveyed through situational context.

And this may not be limited to facial cues.

“Consider intense vocal expressions of grief versus joy or pleasure versus pain,” the researchers wrote in their paper. For example, imagine sitting in a coffee shop and hearing someone behind you shriek. Is it immediately obvious whether the emotion is a positive or negative one?

“When people are experiencing a very high level of excitation,” Dr. Aviezer said, “then we see this overlap in expressions.”

Shooting reported at Houston college, at least two wounded

Shooting at Lone Star College Raw

By Matt Pearce

January 22, 2013, 11:37 a.m.

At least two people were wounded in a Tuesday shooting at Lone Star College in north Houston, according to initial reports.

Helicopter video, carried by CNN, showed at least one victim wearing a neck brace being wheeled on a stretcher to an ambulance.

CNN reported that a suspect was in custody but that could not be immediately confirmed.

TIMELINE: U.S. mass shootings 

Students were shown jogging away, with their hands up, as police entered a building on or near the campus. Students were later shown walking calmly as police vehicles remained massed around the campus.

KTRK-TV reported that officials were focusing on the campus' library. The station showed a victim being wheeled into Ben Taub General Hospital after the shooting.

"We know that shots have been fired and we are in a shelter-in-place situation on the campus," Vicki Cassidy, manager of media relations for Lone Star College System, told the Houston Chronicle. "It's a pretty chaotic scene at this point in time."

An alert posted on the school's website at 12:47 p.m. advised students, faculty and staff "to take immediate shelter where you are."

The Harris County Sheriff's Office said it would post more information on its Facebook account as it becomes available.
