Rihanna a rock star on Victoria's Secret catwalk

NEW YORK (AP) — Rihanna rocked the lingerie look at Wednesday night's Victoria's Secret fashion show in New York, providing the highlight of the live-music soundtrack and holding her own on the catwalk with some of the world's top models.

And those models even had props, including Adriana Lima's ringmaster wand, Doutzen Kroes' body cage and several pairs of the oversized wings that the retailer has made its signature. It would be a close contest who got the biggest wings: Toni Garrn's giant poppy pair or Miranda Kerr's swan-style feathered pouf. Only Lily Aldridge could boast star-spangled wings that shot out silver sparkles.

Alessandra Ambrosio's orchid-petal wings might have lacked a little grandeur, but she made up for it with a $2.5 million jeweled "floral fantasy bra."

Still, wearing a sheer pink mini that gave glimpses of her bra, Rihanna sang "Fresh Out the Runway" at the end of the corset-and-garter parade and she was the one to grab the audience's biggest applause.

The fashion show has become a pre-holiday season tradition for the retailer. CBS will turn it into a one-hour special, which also had performances from Justin Bieber and Bruno Mars, to be shown on Dec. 4.

This year's event had a slight twist. It started with an announcer noting that Victoria's Secret and CBS had each made a donation to relief efforts for Superstorm Sandy, and a thank you to the National Guard members who are based out of the Lexington Avenue Armory that has for years been home to the show.

Mostly, though, models are encouraged to smile, ham it up and show off the extra time at the gym that most admit to in the weeks beforehand. "It's highly televised, and you take that into consideration," said model Joan Smalls ahead of the show. "This is kind of not the same as other runways. You have to prepare your body: No. 1 is the wings are heavy, and No. 2 is you have to be comfortable with your body because the camera will pick up on it if you're not comfortable and confident."

There's an emphasis on glitz, skin and dramatic production here, not wearable undergarment trends for typical Victoria's Secret shoppers. It was divided into six sections: Circus, complete with acrobats, contortionists and a sword eater; Dangerous Liaisons; Pink Is Us; Silver Screen Angels; Angels in Bloom; and Calendar Girls, which allowed Bruno Mars to serenade a model for each month of the year.

For his first song, "Beauty and the Beat," Bieber, wearing low-slung white pants and a white leather studded vest, sat alone with his guitarist in the mellowest part of the show. For "As Long As You Love Me," however, he brought in backup dancers and interacted with the models while moving around a giant makeshift pinball machine.

"It's like a dream come true," said Bieber on the pink carpet before the show. "I would rather be here than anywhere in the world."

Experts raise concerns over superhuman workplace

LONDON (AP) — Performance-boosting drugs, powered prostheses and wearable computers are coming to an office near you — but experts warned in a new report Wednesday that too little thought has been given to the implications of a superhuman workplace.

Academics from Britain's leading institutions say attention needs to be focused on the consequences of technology which may one day allow — or compel — humans to work better, longer and harder. Here's their list of upgrades that might make their way to campuses and cubicles in the next decade:

BRAIN BOOSTERS

Barbara Sahakian, a Cambridge neuropsychology professor, cited research suggesting that 16 percent of U.S. students already use "cognitive enhancers" such as Ritalin to help them handle their course loads. Pilots have long used amphetamines to stay alert. And at least one study has suggested that the drug modafinil could help reduce the number of accidents experienced by shift workers.

But bioethicist Jackie Leach Scully of northern England's Newcastle University worries that the use of such drugs might focus on worker productivity over personal well-being.

"Being more alert for longer doesn't mean that you'll be less stressed by the job," she said. "It means that you'll be exposed to that stress for longer and be more awake while doing it."

WEARABLE COMPUTERS

The researchers also noted so-called "life-logging" devices like Nike Inc.'s distance-tracking shoes or wearable computers such as the eyeglasses being developed by Google Inc. The shoes can record your every step; the eyeglasses everything you see. Nigel Shadbolt, an expert in artificial Intelligence at southern England's University of Southampton, said such devices were as little as 15 years away from being able to record every sight, noise and movement over an entire human life.

So do you accept if your boss gives you one?

"What does that mean for employee accountability?" Shadbolt asked.

BIONIC LIMBS — AND BEYOND

The report also noted bionic limbs like the one used this week by amputee Zac Vawter to climb Chicago's Willis Tower or exoskeletons like the one used earlier this year by partially paralyzed London Marathon participant Claire Lomas. It also touched on the development of therapies aimed at sharpening eyesight or cochlear implants meant to enhance hearing.

Scully said any technology that could help disabled people re-enter the workforce should be welcomed but society needs to keep an eye out for unintended consequences.

"One of the things that we know about technology hitting society is that most of the consequences were not predicted ahead of time and a lot of things that we worry about ahead of time turn out not to be problems at all," she said. "We have very little idea of how these technologies will pan out."

THE PRESSURIZED WORKPLACE

The report was drawn up by scientists from The Academy of Medical Sciences, the British Academy, the Royal Academy of Engineering and the Royal Society.

"We're not talking science fiction here," said Genevra Richardson, the King's College law professor who oversaw the report. "These technologies could influence our ability to learn or perform tasks, they could influence our motivation, they could enable us to work in more extreme conditions or in old age, or they could facilitate our return to work after illness or disability .... Their use at work also raises serious ethical, political and economic questions."

Scully said workers may come under pressure to try a new memory-boosting drug or buy the latest wearable computer.

"In the context of a highly pressurized work environment, how free is the choice not to adopt such technologies?" she said.

Union representatives appeared taken aback by some of the experts' predictions. One expressed particular disquiet at the possibility raised by the report that long-distance truck drivers might be asked to take alertness drugs for safety reasons.

"We would be very, very against anything like that," said James Bower, a spokesman for Britain's United Road Transport Union. "We can't have a situation where a driver is told by his boss that he needs to put something in his body."

How did America become so polarized?

WASHINGTON (AP) — The election laid bare a dual — and dueling — nation, politically speaking, jaggedly split down the middle on the presidency and torn over much else. It seems you can please only half of the people nearly all of the time.

Americans retained the fractious balance of power in re-electing President Barack Obama, a Republican House and a Democratic Senate, altogether serving as guarantors of the gridlock that voters say they despise. Slender percentages separated winner and loser from battleground to battleground, and people in exit polls said yea and nay in roughly equal measure to some of the big issues of the day.

Democracy doesn't care if you win big, only that you win. Tuesday was a day of decision as firmly as if Obama had run away with the race. Democrats are ebullient and, after a campaign notable for its raw smackdowns, words of conciliation are coming from leaders on both sides, starting with the plea from defeated Republican rival Mitt Romney that his crestfallen supporters pray for the president.

But after the most ideologically polarized election in years, Obama's assertion Wednesday morning that America is "more than a collection of red states and blue states" was more of an aspiration than a snapshot of where the country stands.

"It's going to take a while for this thing to heal," said Ron Bella, 59, a Cincinnati lawyer who lives in Alexandria, Ky. He is relieved Obama won, but some of his co-workers are in a "sour mood" about it.

"They feel like the vast majority of the country wanted Romney, and the East and the West coasts wanted Obama," he said. "I'm not sure exactly why that is, but there just seems to be such hatred for Obama out there."

Compromise was a popular notion in the hours after Obama's victory and an unavoidable one, given the reality of divided government. But the familiar contours of partisan Washington were also in evidence, especially the notion that compromise means you do things my way.

As Democratic Rep. Steve Israel of New York put it, "If you refuse to compromise, we are going to beat you." Israel, chairman of the Democratic Congressional Campaign Committee, said the election showed "if you are an extremist tea party Republican, you are going to lose."

Senate Republican Leader Mitch McConnell of Kentucky said pointedly that Republicans will meet Obama halfway "to the extent he wants to move to the political center" and propose solutions "that actually have a chance of passing."

In New York's bustling Times Square, hope, skepticism and the usual polarities were all to be found when people talked about the president. "He may not have done a great job in my mind but I kinda trust him," said Jerry Shul. "I have faith he will get with the Republicans and get something done."

A less-flattering George Dallemand called this "a moment of truth" for the country. "I guess we have to wish for the best now, but I still think he is socialism."

In Miami, Karen Fitzgerald, 55, wore a black dress and said she was in mourning over Romney's defeat.

"It's an upsetting day," she said. But she took some comfort from her Democratic friends on Facebook, who have stopped chiding the other side in their posts. "Now they're all saying we need to work together and be united," she said. "Maybe we can."

In Springfield, Ohio, an "elated" Frank Hocker, 67, hoped Republicans would get the message to get out of Obama's way. "There was a backlash," he said. "For this obstructionist House and those tea party people, I hope they learned their lesson. I hope they learned their lesson: Don't stop the progress of this country."

In Chicago, Obama supporter Scherita Parrish, 56, predicted the president will reach out to Republicans but may not get much back.

"But the people have spoken," she said. "They need to lick their wounds, get on with it and start working with the president."

Unity is a challenge not just for Obama but for the Republicans, who won less than 30 percent of the growing Hispanic vote and not even one in 10 black voters. Obama built a strong Electoral College majority, if only a narrow advantage in the popular vote, despite losing every age group of non-Hispanic white voters.

Surveys of voters found Obama's health care law to be as divisive as ever, with just under 50 percent wanting it repealed in whole or part, and 44 percent liking it as is or wanting more of it.

But democracy doesn't care about exit polls, either, and the election almost certainly means Republicans can forget about trying to roll it back now.

In reaffirming divided government, though, Americans all but ensured colossal fights are ahead over the shape of government and Obama's agenda. He is out to break a wall of Republican opposition to tax increases on the wealthy — a move that about half the voters in exit polls thought was a good idea. And extraordinarily difficult negotiations are imminent as the president and Congress try to make a deal to avoid the "fiscal cliff" — steep spending cuts and a variety of tax increases in January.

In the end, voters split about equally on whether Obama or Romney would be better at handling the economy.

Then again, they were divided down the middle on whether Obama or his predecessor, George W. Bush, deserves most of the blame for the economy's problems.

So it goes in the 50-50 nation, give or take.

Quiet media night explodes suddenly, Rove protests

NEW YORK (AP) — Careful media coverage of a close presidential election Tuesday exploded so suddenly Tuesday that it left the bizarre spectacle of Fox News Channel analyst Karl Rove, a major fundraiser for Republican Mitt Romney, publicly questioning his network's declaration that President Barack Obama had been re-elected.

ABC News was also frantically trying to repair a power outage that left much of its set inoperable precisely at the time the election was being decided.

For several hours, election coverage resembled the run-up to a Super Bowl, with plenty of talk signifying little. Then NBC News, at 11:12 p.m. ET, was the first to declare Obama had won by virtue of winning the battleground state of Ohio. "He remains president of the United States for a second term," said anchor Brian Williams.

Other networks followed suit, including Fox five minutes later. But Rove, the former top political aide to President George W. Bush whose on-air presence on Fox this campaign raised some eyebrows because of his prominent role supporting Romney, suggested the call was premature.

"We've got to be careful about calling things when we have like 991 votes separating the candidates and a quarter of the vote left to count ... I'd be very cautious about intruding in this process," said Rove, a behind-the-scenes player in the wild 2000 election between Bush and Al Gore that took weeks to decide. (Gore was on TV Tuesday, too, as anchor of Current TV's election coverage).

It left Rove's colleagues struggling for words.

"That's awkward," said co-anchor Megyn Kelly. She then went backstage to interview on camera two men who were part of Fox's team in charge of making election calls. They had concluded that based on the precincts where votes were left to be counted, Romney couldn't beat Obama.

Later, Rove tried to make light of the encounter. "This is not a cage match," he said. "This is a light intellectual discussion."

As the evening had progressed for Fox and it became clear that Romney, the clear favorite of most of its audience, would find it hard to win, commentators like Sarah Palin and Peggy Noonan looked stricken.

"This was the referendum that Mitt Romney wanted on Barack Obama," said Huffington Post's Howard Fineman on MSNBC. "And guess what? Barack Obama won the referendum. And that's pretty darned emphatic."

Much of ABC's New York election studio was left powerless for about 20 minutes at the height of Tuesday's coverage. The network didn't inform viewers, and tried to compensate by taking anchors Diane Sawyer and George Stephanopoulos away from their desks, and cutting away to crowd shots at Times Square.

Sawyer's relaxed, folksy delivery in her first presidential election night as anchor drew considerable social media attention. The rock group They Might Be Giants tweeted: "and Diane Sawyer declares tonight's winner is ... chardonnay!"

Sawyer and Stephanopoulos were a new election anchor team for ABC, and Scott Pelley led the CBS coverage. Of the three anchors for the biggest broadcast networks, only NBC's Williams was a returnee from 2008.

But it was a far different media world anyway. 2012 was notable for the vast array of outlets that an interested consumer could command to create their own media experience on multiple screens. Web sites offered deep drill-downs in data and social media hosted raucous conversations.

"If you started a drinking game with the words 'exit poll' in it, please stop now. You will die!" tweeted TV critic Tim Goodman.

Obama's Twitter account tweeted a picture of the president hugging First Lady Michelle Obama, and within 45 minutes it was retweeted more than 300,000 times.

Earlier in the evening, journalists took special care not to rely too heavily on exit polls. Perhaps they remembered how misleading exit polls in 2004 led TV networks astray then or perhaps, in CBS' Bob Schieffer's words, its results this year were too contradictory.

News outlets carefully parsed information and sometimes used the same facts for contradictory conclusions.

Fox News analyst Brit Hume noted an exit poll finding that 42 percent of voters said Superstorm Sandy was an important factor in their vote, suggesting that was a positive for Obama since he was widely considered to have been effective in his response. With the same information, the web site Politico headlined: "Exit Survey: Sandy Not a Factor."

There was a certain amount of vamping time, too. Glenn Beck's online network, The Blaze, had a blackboard straight out of the 1960s as a tote board. Beck killed time on the air by asking for cookie dough ice cream from the on-set food bar.

"Waffle cone, please," Beck said.

When Sawyer asked David Muir for the latest news from the Romney campaign, he reported the family had pasta for dinner and the candidate indulged in his favorite peanut butter and honey sandwich.

The media personality with perhaps the most on the line was Nate Silver of The New York Times, whose FiveThirtyEight blog was sought out by 20 percent of the people who visited the newspaper's website on Monday. He has used statistical data throughout the campaign to predict an Obama victory and by Tuesday, had forecast a 90.9 percent chance that Obama would win.

After Obama's victory became clear, Gavin Purcell, producer of "Late Night with Jimmy Fallon," tweeted that "Nate Silver is the only white male winning tonight." CNN's Piers Morgan tweeted Silver an invitation to appear on his show Wednesday.

Study: Stem cells from strangers can repair hearts

LOS ANGELES (AP) — Researchers are reporting a key advance in using stem cells to repair hearts damaged by heart attacks. In a study, stem cells donated by strangers proved as safe and effective as patients' own cells for helping restore heart tissue.

The work involved just 30 patients in Miami and Baltimore, but it proves the concept that anyone's cells can be used to treat such cases. Doctors are excited because this suggests that stem cells could be banked for off-the-shelf use after heart attacks, just as blood is kept on hand now.

Results were discussed Monday at an American Heart Association conference in California and published in the Journal of the American Medical Association.

The study used a specific type of stem cells from bone marrow that researchers believed would not be rejected by recipients. Unlike other cells, these lack a key feature on their surface that makes the immune system see them as foreign tissue and attack them, explained the study's leader, Dr. Joshua Hare of the University of Miami.

The patients in the study had suffered heart attacks years earlier, some as long as 30 years ago. All had developed heart failure because the scar tissue from the heart attack had weakened their hearts so much that they grew large and flabby, unable to pump blood effectively.

Researchers advertised for people to supply marrow, which is removed using a needle into a hip bone. The cells were taken from the marrow and amplified for about a month in a lab at Baltimore's Johns Hopkins University, then returned to Miami to be used for treatment, which did not involve surgery.

The cells were delivered through a tube pushed through a groin artery into the heart near the scarred area. Fifteen patients were given cells from their own marrow and 15 others, cells from strangers.

About a year later, scar tissue had been reduced by about one-third. Both groups had improvements in how far they could walk and in quality of life. There was no significant difference in one measure of how well their hearts were able to pump blood, but doctors hope these patients will continue to improve over time, or that refinements in treatment will lead to better results.

The big attraction is being able to use cells supplied by others, with no blood or tissue matching needed.

"You could have the cells ready to go in the blood bank so when the patient comes in for a therapy — there's no delay," Hare said. "It's also cheaper to make the donor cells," and a single marrow donor can supply enough cells to treat as many as 10 people.

Dr. Elliott Antman of Harvard-affiliated Brigham and Women's Hospital in Boston who heads the heart conference, praised the work.

"That opens up an entire new avenue for stem cell therapy, like a sophisticated version of a blood bank," he said. There's an advantage in not having to create a cell therapy for each patient, and it could spare them the pain and wait of having their own marrow harvested, he said.

The study was sponsored by the National Institutes of Health. Hare owns stock in a biotech company working on a treatment using a mixture of cells.

Juan Lopez received his own cells in the study, and said it improved his symptoms so much that at age 70, he was able to return to his job as an engineer and sales manager for a roofing manufacturer and ride an exercise bike.

"It has been a life-changing experience," said Lopez, who lives in Miami. "I can feel day by day, week by week, month by month, my improvement. I don't have any shortness of breath and my energy level is way up there. I don't have any fluid in my lungs."

And, he said happily, "My sex drive has improved!"

'We remain more than a collection of red states and blue states'

President Barack Obama handily defeated Gov. Mitt Romney and won himself a second term on Tuesday after a bitter and historically expensive race that was primarily fought in just a handful of battleground states. Obama beat Romney after nabbing almost every one of the 12 crucial battleground states.

The Romney campaign's last-ditch attempt to put blue-leaning Midwestern swing states in play failed as Obama's Midwestern firewall sent the president back to the White House for four more years. Obama picked up the swing states of New Hampshire, Michigan, New Mexico, Iowa, Virginia, Wisconsin, Colorado, Nevada, Pennsylvania, Minnesota and Ohio. Of the swing states, Romney picked up only North Carolina. Florida is still too close to call, but even if Romney wins the state, Obama still beat him in the Electoral College vote. The popular vote will most likely be narrower than the president's decisive Electoral College victory.

In a sweeping victory speech early Wednesday morning, Obama thanked every American who voted, and vowed to work with leaders from both parties to tackle the country's challenges.

"Our economy is recovering, a decade of war is ending, a long campaign is now over," he told a crowd of cheering supporters in Chicago. "And whether I earned your vote or not, I have listened to you, I have learned from you and you have made me a better president." Obama added he has "never been more hopeful about America. ... We're not as divided as our politics suggest. We remain more than a collection of blue states and red states."

In his speech, he offered clues to the policy goals of his second term, which included a deficit reduction plan that combines tax increases with spending cuts, a comprehensive overhaul of the nation's federal immigration laws and tax reform. He called on Republicans to join him in achieving those goals.

The battle for the White House between Obama and Romney divided the nation, causing, at times, bitter disputes between the parties. Obama urged his supporters to look beyond fight of the past several months and defended the process of choosing a president.

"I know that political campaigns can sometimes seem small, even  silly," Obama said. "And that provides plenty of fodder for the cynics who tell us  that politics is nothing more than a contest of evils or the domain of  special interests. If you ever get the chance to talk to folks who  turned out to our rallies and along the rope lines of high school gyms,  or saw folks working late at campaign office or some tiny county a long  way from home, you'll discover something else."

Romney conceded in Boston in a speech around 1 a.m. ET. "Like so many of you, Paul [Ryan] and I have left everything on the field. We have given our all to this campaign," Romney said. "I so wish that I had been able to fulfill your hopes to lead your country in another direction. But the nation chose another leader." Romney congratulated the president and his campaign on their victory.

The Obama victory marks an end to a years-long campaign that saw historic advertisement spending levels, countless rallies and speeches, and three much-watched debates.

The Romney campaign cast the election as a referendum on Obama's economic policies, frequently comparing him to former President Jimmy Carter and asking voters the Reagan-esque question of whether they are better off than they were four years ago. But the Obama campaign pushed back, blanketing key states such as Ohio early on with ads painting him as a multimillionaire more concerned with profits than people. The Obama campaign also aggressively attacked Romney on reproductive rights issues, tying Romney to a handful of Republican candidates who made controversial comments about rape and abortion.

The ads were one reason Romney faced a steep likeability problem for most of the race, until his expert performance at the first presidential debate in Denver in October. After that debate, and a near universal panning of Obama's performance, Romney caught up with Obama in national polls, and almost closed his favorability gap with the president. In polls, voters consistently gave him an edge over Obama on who would handle the economy better and create more jobs, even as they rated Obama higher on caring about the middle class.

But the president's Midwestern firewall—and the campaign's impressive grassroots operation—carried him through. Ohio tends to vote a bit more Republican than the nation as a whole, but Obama was able to stave off that trend and hold an edge there over Romney, perhaps due to the president's support of the auto bailout three years ago. Romney and his running mate, Paul Ryan, all but moved to Ohio in the last weeks of the campaign, trying and ultimately failing to erase Obama's lead there.

A shrinking electoral battleground this year meant that only 12 states were really seen as in play, and both candidates spent most of their time and money there. Though national polls showed the two candidates in a dead heat, Obama consistently held a lead in the states that mattered. That, and his campaign's much-touted get-out-the-vote efforts and overall ground game, may be what pushed Obama over the finish line.

Now, Obama heads back to office facing what will most likely be bitterly partisan negotiations over whether the Bush tax cuts should expire. The House will still be majority Republican, with Democrats maintaining their majority in the Senate.

The loss may provoke some soul searching in the Republican Party. This election was seen as a prime opportunity to unseat Obama, as polls showed Americans were unhappy with a sluggish economy, sky-high unemployment and a health care reform bill that remained widely unpopular. Romney took hardline positions on immigration, federal spending and taxes during the long Republican primary when he faced multiple challenges from the right. He later shifted to the center in tone on many of those issues, but it's possible the primary painted him into a too-conservative corner to appeal to moderates during the general election. The candidate also at times seemed unable to effectively counter Democratic attacks on his business experience and personal wealth.

"In the coming weeks and months I am looking forward to reaching out to leaders of both parties," Obama said.

He won't have much time to fulfill that promise. With tax hikes looming and a sequestration deal that will make enormous , automatic cuts in government funding, Congress and the White House must move quickly to find a compromise and put Obama's high minded rhetoric into action.

Elephant in South Korean zoo imitates human speech

SEOUL, South Korea (AP) — An elephant in a South Korean zoo is using his trunk to pick up not only food, but also human vocabulary.

An international team of scientists confirmed Friday what the Everland Zoo has been saying for years: Their 5.5-ton tusker Koshik has an unusual and possibly unprecedented talent.

The 22-year-old Asian elephant can reproduce five Korean words by tucking his trunk inside his mouth to modulate sound, the scientists said in a joint paper published online in Current Biology. They said he may have started imitating human speech because he was lonely.

Koshik can reproduce "annyeong" (hello), "anja" (sit down), "aniya" (no), "nuwo" (lie down) and "joa" (good), the paper says.

One of the researchers said there is no conclusive evidence that Koshik understands the sounds he makes, although the elephant does respond to words like "anja."

Everland Zoo officials in the city of Yongin said Koshik also can imitate "ajik" (not yet), but the researchers haven't confirmed the accomplishment.

Koshik is particularly good with vowels, with a rate of similarity of 67 percent, the researchers said. For consonants he scores only 21 percent.

Researchers said the clearest scientific evidence that Koshik is deliberately imitating human speech is that the sound frequency of his words matches that of his trainers.

Vocal imitation of other species has been found in mockingbirds, parrots and mynahs. But the paper says Koshik's case represents "a wholly novel method of vocal production" because he uses his trunk to reproduce human speech.

In 1983, zoo officials in Kazakhstan reportedly claimed that a teenage elephant named Batyr could reproduce Russian to utter 20 phrases, including "Batyr is good." But there was no scientific study on the claim.

Researchers believe Koshik learned to reproduce words out of a desire to bond with his trainers after he was separated from two other elephants at age 5.

Koshik emerged as a star among animal enthusiasts and children in South Korea after Everland Zoo claimed in 2006 that he could imitate words, two years after his trainers noticed the phenomenon. His growing reputation prompted Austrian biologist Angela Stoeger-Horwath and German biophysicist Daniel Mietchen to study him in 2010, zoo officials said.

Oh Suk-hun, a South Korean veterinarian who co-authored the research paper with Stoeger-Horwath and Mietchen, said the elephant apparently started imitating human speech to win the trust of his trainers.

In April, a children's science book called "Joa Joa, Speaking Elephant" was published. The cover photo showed Koshik opening his mouth wide while raising a trunk over his trainer's head.

Researchers said Koshik was trained to obey several commands and "exposed to human speech intensively" by trainers, veterinarians and zoo visitors.

Shin Nam-sik, a veterinary professor at Seoul National University who has seen Koshik, agreed with researchers' finding that the elephant was able to mimic human speech.

"In Koshik's case, the level of intimacy between him and his trainer was the key factor that made the elephant want to sound like a human," Shin said.

Kim Jong-gab, Koshik's chief trainer, said the elephant was timid for a male when he first came to Everland Zoo, so trainers often slept in the same area with him. Kim thinks that contact helped Koshik feel closer to humans.

Kim said he has another phrase he wants to teach Koshik: "Saranghae," or "I love you."
