French, Malian forces fight Islamist rebels in Gao

GAO, Mali (Reuters) - French and Malian troops fought Islamists on the streets of Gao and a car bomb exploded in Kidal on Thursday, as fighting showed little sign of abating weeks before France plans to start withdrawing some forces.

Reuters reporters in Gao in the country's desert north said French and Malian forces fired at the mayor's office with heavy machineguns after Islamists were reported to have infiltrated the Niger River town during a night of explosions and gunfire.

French Defense Minister Jean-Yves Le Drian told a news conference in Brussels that Gao was back under control after clashes earlier in the day.

"Malian troops supported by French soldiers killed five jihadists and the situation is back to normal," he said.

In Kidal, a remote far north town where the French are hunting Islamists, residents said a car bomb killed two. A French defense ministry source reported no French casualties.

French troops dispatched to root out rebels with links to al Qaeda swiftly retook northern towns last month. But they now risk being bogged down in a guerrilla conflict as they try to help Mali's weak army counter bombings and raids.

"There was an infiltration by Islamists overnight and there is shooting all over the place," Sadou Harouna Diallo, Gao's mayor, told Reuters by telephone earlier in the day, saying he was not in his office at the time.

Gao is a French hub for operations in the Kidal region, about 300 km (190 miles) northeast, where many Islamist leaders are thought to have retreated and foreign hostages may be held.

"They are black and two were disguised as women," a Malian soldier in Gao who gave his name only as Sergeant Assak told Reuters during a pause in heavy gunfire around Independence Square.

Six Malian military pickups were deployed in the square and opened fire on the mayor's office with the heavy machineguns. Two injured soldiers were taken away in an ambulance.

French troops in armored vehicles later joined the battle as it spilled out into the warren of sandy streets, where, two weeks ago, they also fought for hours against Islamists who had infiltrated the town via the nearby river.

Helicopters clattered over the mayor's office, while a nearby local government office and petrol station was on fire.

A Gao resident said he heard an explosion and then saw a Malian military vehicle on fire in a nearby street.

Paris has said it plans to start withdrawing some of its 4,000 troops from Mali next month. But rebels have fought back against Mali's weak and divided army, and African forces due to take over the French role are not yet in place.

Islamists abandoned the main towns they held but French and Malian forces have said there are pockets of Islamist resistance across the north, which is about the size of France.

CAR BOMB

Residents reported a bomb in the east of Kidal on Thursday.

"It was a car bomb that exploded in a garage," said one resident who went to the scene but asked not to be named.

"The driver and another man were killed. Two other people were injured," he added.

A French defense ministry official confirmed there had been a car bomb but said it did not appear that French troops, based at the town's airport, had been targeted.

Earlier this week, a French soldier was killed in heavy fighting north of Kidal, where French and Chadian troops are hunting Islamists in the Adrar des Ifoghas mountains, which border Algeria.

Operations there are further complicated by the presence of separatist Tuareg rebels, whose rebellion triggered the fighting in northern Mali last year but were sidelined by the better-armed Islamists.

Having dispatched its forces to prevent an Islamist advance south in January, Paris is eager not to become bogged down in a long-term conflict in Mali. But their Malian and African allies have urged French troops not to pull out too soon.

Why Twitter Makes Us Want to Add Extra Letterssss

For the March issue of The Atlantic, I spoke with linguists about this thingggg we’re doing with words — a growing habit in which otherwise reasonable people cavalierly add extra letters to the words in their texts, emails, tweets, and so forth — to find out why. One of the experts I met while working on that piece was Tyler Schnoebelen, a recent PhD from Stanford who wrote his dissertation on emotion in language and blogs about newsworthy word-findings at Corpus Linguistics. He’s been focusing lately on the phenomenon of word lengthening or “expressive lengthening” on Twitter. (He’s also one of the researchers behind a recent study about how men and women tweet.) For his dissertation, he analyzed data consisting of 3,775,174 tweets from 102,304 different English-speaking authors, tweeted in the six months between January to June of 2011 in the U.S. He was looking at the way people used emoticons in their tweets, but in that exploration he found something else: Along with those emoticons, people were adding letters to their words, too. Or toooooo. In the interest of learning more about why word lengthening exists, even on an inherently character-limited social media platform like Twitter, I turned to him with a few questions. 

RELATED: Exploring the Character of a Bad Word

What words get lengthened the most on Twitter, and why? The main ones are the expressive things you don’t think of as words — mmmm, oh, ah, aw. You can put as many letters on those as you want. That gets extended to words like hey, no, yes, and the letters that get extended are usually the ones you can hold onto, vowels or ns or ses. Then it gets even crazier — OMgggg or LMAOoo or LOLlll, though you’re not actually saying “laughing my ass off off off” or “laugh out loud loud loud loud.” From that there’s extending real words you can’t pronounce, shittttt or happppppy or amazinggggg. You start with these expressions that don’t have a proper spelling, things no one tells you how to write, and you add and go beyond that to make words more affective and expressive.

RELATED: David Cameron’s Semantic Chauvinism

You wrote a post about a friend who’d seen the word dumb tweeted as DUMBBB, which inspired you to take a look at which specific letters were added most frequently and why. Ooo was a big winner. Why do you think people pick the particular letters they do?  People love the o! I think it’s something about rounding your lips; it’s iconic of getting your mouth around something. Your lips, pursing forward, going out into the world … there’s something there. 

RELATED: The Ways in Which We Mistake Our Words

What about the more unusual added letters, like b or g? I think the gs are the most fun. People who use them are really taking this idea that you can extend things and going crazy with it. You can’t pronounce a word like Omgggg, but it’s been lifted away from the speech itself. In real speech, which is normally face to face, there are so many different ways to communicate — I’m not just happy but really happy — but we don’t have that in a tweet or text or email. Adding letters is a version of a big intonation, raised eyebrows. 

RELATED: Geoffrey Chaucer Coined ‘Twitter’

In terms of voicing, vowels make sense to lengthen because when we’re speaking that’s what we’re doing. Sometimes there are consonants, s or n, we do that in speech, too. But you don’t pronounce the b in dumb in English, so what does adding that letter mean? The end is a nice attractive spot, maybe, that gets across that you’re doing something. Clearly when people are doing this they’re being playful.  

RELATED: Embracing the Age of Autocorrect

So this is all about adding feeling to our too-brief 140-character missives? It’s not a waste of space, I guess, because of emotional layering gained? If you look at these words, a lot of them are from the expressive class. You’re already expressing some emotional state with them — aw — or you’re using them for augmentative purposes, like so and lots of affirmatives and negations: yeahhh, nooo, yesssss. But I think it’s telling that some of the other more frequent words that get extra letters are unpronounceable. People are trying to give some flavor to the communication. These additions really help get the point across and share intonation. That’s part of it: You can hear them in your ear.

Are specific usages unique to different people or subsets of Twitter? People using LMFAOOO tend to talk about Chris Brown and Nicki Minaj; there’s a hip-hop feel to that. People who write knowww with extra ws or youuu with extra us also use the word mum, they spell thankyou as one word, and they use xoxoxo.

Do you add letters to tweets or emails or texts? I’m a fond of adding extra ooos like most poeple. I don’t think I do it excessively. I tend to make my hms a single. 

There’s also a kind of a social meme-ing to these things. I’m tempted to use v. for very but I can’t help but associate that with Bridget Jones, who does that in her diary, and I have a problem with someone reading me as Bridget Jones. I tentatively aded a v. in a tweet the other day. I rearranged and deleted and put it back several times. Other people may not have a reference like this.

It makes you wonder how long the “curse of Bridget Jones” will hold. Speaking of things evolving and changing, this kind of behavior tends to inspire rants about how proper language and grammar is dying. What do you think about that?  As far as I understand, [the ranters] are full of it. This represents changing conventions; we’re not becoming impaired. We all have cues, while we’re talking on the phone, for instance, and we’d have even more if we were face to face. What we’re usually doing is negotiating what we know about a particular person and what we know about people in general. It has to do with expectations, my experience with you and everybody else. We generally accommodate each other. Over the course of a conversation, our vowels become more alike. Any of these things can be going on below our level of awareness, or they can come up to our level of awareness. We can tweak them, we can notice them.

Your research focused on tweets in which people had used emoticons. Do you think emoticon-users are more likely to add letters to the words they tweet?  They very much do exist together, emoticons and adding letters. It’s easy to call these habits nonstandard, but whether they’re really nonstandard …10 percent of tweets use emoticons. As for the percent of letters added to words, I don’t know. They’re clearly very frequent, especially the expressive sound ones. Emoticons and added letters are not warring with each other; in fact, they go together very well. It’s speculation, but my guess is, if you’re fine with lengthening, you’re probably fine adding emoticons.

What other things do people do on Twitter in order to convey emotion?  Other types of punctuation. You can underline, you can bold, you can do all caps. People do all caps all the time. Putting asterisks around words has existed for a long time, and tends to be used on the internet with verbs indicating what you are doing at the moment (*smiles*). Or you see underscore, word, underscore. Those punctuation techniques will give you a sense that this is important, but not a sense of how it’s said. The all-caps gives you a sense of how it’s said, but many people hear or read it as shouting, and you don’t always mean to do that. The awwwww (expressing condolences) is not something you shout. You can’t shout mmmm.

Mmmmm. Do you see an end to the “trend” of adding letters? Once we get to the point of digesting audio tweets, we won’t need to add letters.

Do the Hemsworth Brothers Have a Type?

Stylewatch
Style News Now

02/20/2013 at 04:30 PM ET

AKM-GSI (2)

Miley Cyrus has been very open about fiancé Liam Hemsworth’s fondness for her bold new do — and he’s obviously a fan of her increasingly funky ensembles as well.

And now that we’ve spotted Hemsworth’s brother Chris out with his wife, Elsa Pataky, who’s rocking a Cyrus-esque ensemble herself, we have to wonder: do the Hemsworth boys have a type?

Both of the Aussie hotties’ significant others share an affinity for shredded denim, chunky engineer boots and choppy, super-short blonde hair.

And when we spotted the tiny girls standing next to the bulky brothers, both clad in V-necks, slouchy jeans and aviators, we admit we had to do a double take to deduce which couple was which.

Fortunately, Chris travels with the ultimate accessory — his adorable baby daughter — which makes them a bit easier to tell apart. But we still have to guess there’s a lot of confusion around the Hemsworth household at holidays.

Tell us: Do you and your siblings go for the same “type?” Are you amused that the Hemsworth boys seem to?

Scientists use 3-D printing to help grow an ear

WASHINGTON (AP) — Printing out body parts? Cornell University researchers showed it's possible by creating a replacement ear using a 3-D printer and injections of living cells.

The work reported Wednesday is a first step toward one day growing customized new ears for children born with malformed ones, or people who lose one to accident or disease.

It's part of the hot field of tissue regeneration, trying to regrow all kinds of body parts. Scientists hope using 3-D printing technology might offer a speedier method with more lifelike results.

If it pans out, "this enables us to rapidly customize implants for whoever needs them," said Cornell biomedical engineer Lawrence Bonassar, who co-authored the research published online in the journal PLoS One.

This first-step work crafted a human-shaped ear that grew with cartilage from a cow, easier to obtain than human cartilage, especially the uniquely flexible kind that makes up ears. Study co-author Dr. Jason Spector of Weill Cornell Medical Center is working on the next step — how to cultivate enough of a child's remaining ear cartilage in the lab to grow an entirely new ear that could be implanted in the right spot.

Wednesday's report is "a nice advancement," said Dr. Anthony Atala, director of the Institute for Regenerative Medicine at Wake Forest Baptist Medical Center, who wasn't involved in the new research.

Three-dimensional printers, which gradually layer materials to form shapes, are widely used in manufacturing. For medicine, Atala said the ear work is part of broader research that shows "the technology now is at the point where we can in fact print these 3-dimensional structures and they do become functional over time."

Today, people who need a new ear often turn to prosthetics that require a rod to fasten to the head. For children, doctors sometimes fashion a new ear from the stiffer cartilage surrounding ribs, but it's a big operation. Spector said the end result seldom looks completely natural. Hence the quest to use a patient's own cells to grow a replacement ear.

The Cornell team started with a 3-D camera that rapidly rotates around a child's head for a picture of the existing ear to match. It beams the ear's geometry into a computer, without the mess of a traditional mold or the radiation if CT scans were used to measure ear anatomy.

"Kids aren't afraid of it," said Bonassar, who used his then-5-year-old twin daughters' healthy ears as models.

From that image, the 3-D printer produced a soft mold of the ear. Bonassar injected it with a special collagen gel that's full of cow cells that produce cartilage — forming a scaffolding. Over the next few weeks, cartilage grew to replace the collagen. At three months, it appeared to be a flexible and workable outer ear, the study concluded.

Now Bonassar's team can do the process even faster by using the living cells in that collagen gel as the printer's "ink." The 3-D technology directly layers the gel into just the right ear shape for cartilage to cover, without having to make a mold first.

The next step is to use a patient's own cells in the 3-D printing process. Spector, a reconstructive surgeon, is focusing on children born without a fully developed external ear, a condition called microtia. They have some ear cartilage-producing cells in that tissue, just not enough. So he's experimenting with ways to boost those cells in the lab, "so we can grow enough of them from that patient to make an ear," he explained.

That hurdle aside, cartilage may be the tissue most amenable to growing with the help of 3-D printing technology, he said. That's because cartilage doesn't need blood vessels growing inside it to survive.

Homebuilding takes a breather; wholesale prices up

WASHINGTON (Reuters) - U.S. builders broke ground on fewer homes last month but a jump in permits for future construction to a 4-1/2-year high indicated the housing market recovery remains on track.

Another report on Wednesday showed wholesale prices rose in January for the first time in four months. However, the gain was smaller than expected and left scope for the Federal Reserve to keep buying bonds to stimulate the economy.

Housing starts dropped 8.5 percent in January to an 890,000-unit annual rate, pulled down by a sharp drop in the volatile multi-family unit category, the Commerce Department said.

Starts for single-family homes hit their highest level since July 2008, and permits for future construction, which lead starts by at least a month, were at their highest level since June 2008.

The drop in starts followed an outsized gain in December and was confined to the Northeast and Midwest, suggesting winter weather likely contributed to the pullback.

"The fundamentals are there and the drivers are looking good," said Patrick Newport, an economist at IHS Global Insight in Lexington, Massachusetts. "We see more new construction this year. The only question is whether it will be in the multi-family or single-family segment."

Housing has shifted from being a headwind for the economy to being a pillar of support, although mortgage rates have crept higher in recent weeks, cooling loan demand.

Luxury homebuilder Toll Brothers on Wednesday reported disappointing quarterly results, hurt in part by lower selling prices, but other homebuilders have been able to take advantage of the recovering market.

A separate report from the Labor Department showed producer prices rose 0.2 percent last month as rebounding food costs offset declining gasoline prices. Wholesale prices had slipped 0.3 percent in December, and economists had expected them to rise 0.4 percent in January.

Food prices accounted for more than 75 percent of the rise in wholesale prices last month.

INFLATION PRESSURES MUTED

Away from the spike in food prices, the producer price report showed inflation pressures were generally muted.

In the 12 months through January, wholesale prices were up 1.4 percent and data on Thursday is expected to show consumer inflation below the U.S. central bank's goal of 2 percent.

"Inflationary pressures remain well contained," said Diane Swonk, chief economist at Mesirow Financial in Chicago. "The Federal Reserve would rather see inflation slightly higher in response to stronger economic conditions than benign because the recovery remains tepid."

In an effort to drive down borrowing costs and spur stronger growth, the Fed last year launched an open-ended bond buying program and said it would keep it up until it saw a substantial improvement in the outlook for the labor market.

But minutes of the U.S. central bank's January 29-30 meeting showed a number of policymakers believed the Fed might have to slow or stop asset purchases before seeing an acceleration in job growth because of concerns over the costs.

U.S. stocks fell on the minutes, with the Standard & Poor's 500 index posting its biggest one day percentage decline since mid-November.

The dollar rose against a basket of currencies. Prices for U.S. Treasury debt ended higher.

Wholesale prices excluding volatile food and energy costs edged up 0.2 percent last month after gaining 0.1 percent in December. In the 12 months through January, those so-called core prices rose 1.8 percent, the smallest gain since February 2011.

A surge in the cost of fresh and dried vegetables pushed up food prices in January. Gasoline prices surprisingly recorded another substantial decline last month, even though prices at the pump have been rising almost every week this year.

The core PPI was lifted by a jump in the cost of drugs, while passenger car and light truck prices fell.

French general urges EU to equip "impoverished" Mali army

BAMAKO, Mali (Reuters) - The European Union should complement a mission to train Mali's army, routed by rebels last year, by providing equipment from uniforms to vehicles and communications technology, a French general said on Wednesday.

General Francois Lecointre, appointed to head the EU training mission to Mali (EUTM) that was formally launched this week, said in Bamako equipping the "very impoverished" and disorganized Malian army was as important as training it.

Europe, along with the United States, has backed the French-led military intervention in Mali which since January 11 has driven al Qaeda-allied Islamist insurgents out of the main northern towns into remote mountains near Algeria's border.

European governments have ruled out sending combat troops to join French and African soldiers pursuing the Islamist rebels.

But the EU is providing a 500-strong multinational training force that will give military instruction to Malian soldiers for an initial period of 15 months at an estimated cost of 12.3 million euros ($16.45 million).

While hailing what he called the EU's "courageous, novel, historic" decision to support Mali, Lecointre told a news conference the Malian army's lack of equipment was a problem.

"I know the Malian state is poor, but the Malian army is more than poor," the French general told a news conference, adding that it urgently needed everything from uniforms and weapons to vehicles and communications equipment.

Last year, when Tuareg separatist forces swelled by weapons and fighters from the Libyan conflict swept out of the northern deserts, a demoralized and poorly-led Malian army collapsed and fled before them, abandoning arms and vehicles.

Mali's military was further shaken by a March 22 coup by junior officers who toppled President Amadou Toumani Toure, sowing division among rival army factions. Islamist radicals allied to al Qaeda later hijacked the victorious Tuareg rebellion to occupy the northern half of the country.

In a fast-charging military campaign led by Paris, French and African troops have driven the jihadists out of principal northern towns like Gao and Timbuktu, and are fighting the rebels in the Adrar des Ifoghas mountains.

HUMAN RIGHTS INSTRUCTION

Flanked by Mali's armed forces chief, General Ibrahima Dembele, Lecointre said he was disappointed that a meeting of international donors last month pledged funds for an African military force, known as AFISMA, being deployed in Mali, but included "very few" contributions for the Malian army itself.

"The European Union needs to invest today in the equipping of the Malian army and not just in its training," the general said, adding he would make this point strongly in a report to EU member state representatives early next month.

Asked how much re-equipping the army would cost, he said it would be "much more" than the 12 million euros of EU financing for the training mission, but could not give a precise estimate.

Starting early in April, the EU mission will start instructing Malian soldiers with a plan to train four new battalions of 600-700 members each, formed from existing enlisted men and new recruits.

Lecointre said the EU training would include instruction in human rights. Demands for this increased after allegations by Malian civilians and international human rights groups that Malian soldiers were executing Tuaregs and Arabs accused of collaborating with Islamist rebels.

The European training contingent is drawn from a range of European countries, but the main contributors would be France, Germany, Italy, Spain and Britain, EUTM officers said.

Mali's army has received foreign training before - several battalions that fled before the rebels last year were trained by the U.S. military and the leader of the March 22 coup, Captain Amadou Sanogo, attended training courses in the United States.

Dembele said U.S. training failed to forge cohesion among Malian units and he hoped the EU training would achieve this.

The United States, which halted direct support for the Malian military after last year's coup, could eventually resume aid if planned national elections in July fully restore democracy to the West African country.

Washington is providing airlift, refuelling and intelligence support to the French-led military intervention in Mali. ($1 = 0.7479 euros)

Jodi Arias Testifies: I Don't Remember Stabbing My Lover 27 Times

Update

By Howard Breuer

UPDATED
02/20/2013 at 05:45 PM EST

• Originally published 02/20/2013 at 05:00 PM EST

Jodi Arias

Charlie Leight/The Arizona Republic/AP

Nearly two months into her murder trial in a Phoenix courtroom, Jodi Arias told jurors Wednesday morning that she killed Travis Alexander in self-defense – but doesn't remember stabbing him nearly 30 times.

"I just remember dropping the knife and being very freaked out and screaming," Arias, 32, said after two weeks of explicit direct testimony about her sex life with Alexander, including their kinky sex shortly before his death. She says the knife was the same one Alexander had used that afternoon when he tied her up for sex.

Facing the death penalty if convicted, Arias says her memory of June 4, 2008, clears up when she put the knife in the dishwasher. Driving off barefoot, she brought with her the rope she said Alexander had used to tie her up and a gun that she pulled from the top of his walk-in closet before shooting him.

"I was very scared and very upset. ... I just wanted to die," Arias testified. "I thought, 'My life is probably done now.'"

She says she decided to bury those feelings and try to act normal as she drove north into Utah to visit another man with whom she already had plans to see.

She says she tossed the gun in the desert, dropped the rope in a Dumpster near St. George, Utah, washed the blood from her hands with a case of bottled Costco water she kept in her trunk and put on a spare pair of work shoes.

The man she met, Ryan Burns, earlier testified that Arias was frisky and affectionate when she visited on June 5. Arias testified that she kissed Burns and cuddled with him the day after killing Alexander because, "I felt safe right there and, I figured, I just wanted to seem normal, like I didn't just do what I just did."

Centerpiece of Defense

Arias's testimony was the long-anticipated centerpiece of her defense. Once that's done, prosecutors are expected to spend several days trying to pick apart her story.

Arias also talked about how she and Alexander, a charismatic Mormon motivational speaker, had an off-and-on relationship in which he sometimes become violent or sadistic.

She says she had arrived at his Mesa, Ariz. home at 5 a.m. and although they took photos and video of themselves having sex, Alexander repeatedly became enraged with her – first for giving him badly scratched CDs of photographs of their trips together, then for dropping his camera.

She says that as Alexander chased her through a walk-in closet "like a linebacker," she grabbed a gun that she knew he kept on a top shelf. She says that she held up the gun, expecting that Alexander would stop charging at her, but he didn't.

"The gun went off, I didn't even mean to shoot, I didn't know my hand was on the trigger," Arias testified. She says that, as they wrestled on the ground, she assumed that she'd shot a hole in the wall, not that she'd hit Alexander. After that, she says, "there's a lot of that day that I don't remember, there's a lot of gaps.

"I have no memory of stabbing him," Arias told jurors, who have heard graphic testimony that Alexander was shot in the head and repeatedly stabbed, and that his throat was slashed ear to ear.

Arias testified she remembers standing in his bathroom, dropping the knife on the hard floor, and thinking, "that I just couldn't believe what had just happened and I couldn't rewind the clock and take it back." She did not recall dragging him to the bathroom or placing him in the shower, she said.

Arias also testified that she still loves Alexander – "It's a different love but yes, I do."

Since the slaying, Arias has changed her story, first saying she had no connection to the crime, then saying two masked intruders killed Alexander and almost killed her. "I basically told everyone what I could remember of the day, and that the intruder story was all B.S.," Arias said Wednesday afternoon at the close of her testimony.

Prosecutors suggest Arias killed Alexander out of jealousy after he pushed her out of his life and started dating someone else, and that the gun was actually a pistol that she stole from her grandparents' home in Yreka, Calif., weeks earlier.

Drug overdose deaths up for 11th consecutive year

CHICAGO (AP) — Drug overdose deaths rose for the 11th straight year, federal data show, and most of them were accidents involving addictive painkillers despite growing attention to risks from these medicines.

"The big picture is that this is a big problem that has gotten much worse quickly," said Dr. Thomas Frieden, head of the Centers for Disease Control and Prevention, which gathered and analyzed the data.

In 2010, the CDC reported, there were 38,329 drug overdose deaths nationwide. Medicines, mostly prescription drugs, were involved in nearly 60 percent of overdose deaths that year, overshadowing deaths from illicit narcotics.

The report appears in Tuesday's Journal of the American Medical Association.

It details which drugs were at play in most of the fatalities. As in previous recent years, opioid drugs — which include OxyContin and Vicodin — were the biggest problem, contributing to 3 out of 4 medication overdose deaths.

Frieden said many doctors and patients don't realize how addictive these drugs can be, and that they're too often prescribed for pain that can be managed with less risky drugs.

They're useful for cancer, "but if you've got terrible back pain or terrible migraines," using these addictive drugs can be dangerous, he said.

Medication-related deaths accounted for 22,134 of the drug overdose deaths in 2010.

Anti-anxiety drugs including Valium were among common causes of medication-related deaths, involved in almost 30 percent of them. Among the medication-related deaths, 17 percent were suicides.

The report's data came from death certificates, which aren't always clear on whether a death was a suicide or a tragic attempt at getting high. But it does seem like most serious painkiller overdoses were accidental, said Dr. Rich Zane, chair of emergency medicine at the University of Colorado School of Medicine.

The study's findings are no surprise, he added. "The results are consistent with what we experience" in ERs, he said, adding that the statistics no doubt have gotten worse since 2010.

Some experts believe these deaths will level off. "Right now, there's a general belief that because these are pharmaceutical drugs, they're safer than street drugs like heroin," said Don Des Jarlais, director of the chemical dependency institute at New York City's Beth Israel Medical Center.

"But at some point, people using these drugs are going to become more aware of the dangers," he said.

Frieden said the data show a need for more prescription drug monitoring programs at the state level, and more laws shutting down "pill mills" — doctor offices and pharmacies that over-prescribe addictive medicines.

Last month, a federal panel of drug safety specialists recommended that Vicodin and dozens of other medicines be subjected to the same restrictions as other narcotic drugs like oxycodone and morphine. Meanwhile, more and more hospitals have been establishing tougher restrictions on painkiller prescriptions and refills.

One example: The University of Colorado Hospital in Aurora is considering a rule that would ban emergency doctors from prescribing more medicine for patients who say they lost their pain meds, Zane said.

M&A deals lift Wall Street shares nearer a record high

NEW YORK (Reuters) - U.S. stocks rose on Tuesday as this year's ongoing surge in merger activity suggested investors were still finding value in the market even as indexes closed in on all-time highs.

Office Depot Inc surged 9.4 percent to $5.02 after a person familiar with the matter said the No. 2 U.S. office supply retailer was in advanced talks to merge with smaller rival OfficeMax Inc , which jumped more than 20 percent.

News of the potential move came just days after Berkshire Hathaway and a partner agreed to acquire H.J. Heinz Co for $23 billion, and following a revised $20 billion takeover of Mexican brewer Grupo Modelo by Anheuser-Busch InBev .

Deal activity has helped equities resist a pullback as investors use dips in stocks as buying opportunities. The S&P is up about 7 percent so far in 2013 and has climbed for the past seven weeks in its longest weekly winning streak since January 2011, though most of the weekly gains have been slim.

The Dow industrials closed 0.9 percent away from their record high while S&P 500 was 2.2 percent off its peak.

"Deals are good for the market," said Frank Lesh, a futures analyst and broker at FuturePath Trading LLC in Chicago. "The fact that they're being done is a positive."

More than $158 billion in deals has been announced so far in 2013, more than double the activity in the same period last year and accounting for 57 percent of global deal volumes, according to Thomson Reuters Deals Intelligence.
