8:16 p.m. CST, January 9, 2013

Carlos Boozer is well on his way to his sixth straight double-double with 14 points and seven rebounds and Nate Robinson replaced an injured Kirk Hinrich with 13 points as the Bulls led the Bucks 57-50 at halftime Wednesday night at the United Center.

The Bulls shot 52.1 percent with 16 assists.

Hinrich missed his fifth game of the season, sitting with a right elbow injury.

"The next guy has to step up," coach Tom Thibodeau said. "We have more than enough. We've been down this road before. Nate, Marquis (Teague), everyone has to be ready."

The Bulls are shooting for their first four-game winning streak this season. The last time these two teams played, the Bulls blew a 27-point, third-quarter lead to lose at home on Nov. 26.

"Their dribble penetration is a big concern," Thibodeau said. "Their athletic bigs are a big factor."

Ersan Ilyasova's 11 points led the Bucks, who trailed by as many as 15 in the first quarter.

Hinrich suffered his injury diving for a loose ball during Monday's victory over the Cavaliers.

‘Smart’ potty or dumb idea? Wacky gadgets at CES

LAS VEGAS (AP) — From the iPotty for toddlers to the 1,600-pound mechanical spider and the host of glitch-ridden “smart” TVs, the International CES show is a forum for gadget makers to take big — and bizarre — chances.

Many of the prototypes introduced at the annual gadget show over the years have failed in the marketplace. But the innovators who shop their wares here are fearless when it comes to pitching new gizmos, many of which are designed to solve problems you didn’t know you had.

A search for this year’s strangest (and perhaps least useful) electronic devices yielded an extra-loud pair of headphones from a metal band, an eye-sensing TV that didn’t work as intended and more. Take a look:

—MOTORHEADPHONES

Bass-heavy headphones that borrow the names of hip-hop luminaries like Dr. Dre have become extremely popular. Rock fans have been left out of the party — until now. British metal band Motorhead, famous for playing gut-punchingly loud, is endorsing a line of headphones that “go to eleven” and are hitting U.S. stores now.

Says lead singer and bassist Lemmy Kilmister, explaining his creative input: “I just said make them louder than everybody else’s. So that’s the only criteria, and that it should reflect every part of the sound, not just the bass.”

The Motorheadphone line consists of three over-the-ear headphones and six in-ear models. The initiative came from a Swedish music-industry veteran, and distribution and marketing is handled by a Swedish company, Krusell International AB.

WHO IT’S FOR: People who don’t care about their hearing. According to Kilmister, the headphones are ideal for Motorhead fans. “Their hearing is already damaged, they better buy these.”

PRICE: Prices range from $ 50 to $ 130.

—EYE-SENSING TV

A prototype of an eye-sensing TV from Haier didn’t quite meet viewers eye-to-eye. An on-screen cursor is supposed to appear where the viewer looks to help, say, select a show to watch. Blinking while controlling the cursor is supposed to result in a click. In our brief time with the TV, we observed may quirks and comic difficulties.

For one, the company’s demonstrator Hongzhao Guo said the system doesn’t work that well when viewers wear eyeglasses. (That kind of defeats the purpose of TV, no?) But it turns out, one bespectacled reporter was able to make it work. But the cursor appeared a couple inches below where the viewer was looking. This resulted in Guo snapping his fingers to attract the reporter’s eye to certain spots. The reporter dutifully looked, but the cursor was always a bit low. Looking down to see the cursor only resulted in it moving further down the TV screen.

WHO IT’S FOR: People too lazy to move their arms.

“It’s easy to do,” Guo said, taking the reporter’s place at the demonstration. He later said the device needs to be recalibrated for each person. It worked fine for him, but the TV is definitely not ready for prime-time.

—PARROT FLOWER POWER

A company named after a bird wants to make life easier for your plants. A plant sensor called Flower Power from Paris-based Parrot is designed to update your mobile device with a wealth of information about the health of your plant and the environment it lives in. Just stick the y-shaped sensor in your plant’s soil, download the accompanying app and — hopefully — watch your plant thrive.

“It basically is a Bluetooth smart low-energy sensor. It senses light, sunlight, temperature, moisture and soil as well as fertilizer in the soil. You can use it either indoors or outdoors,” said Peter George, vice president of sales and marketing for the Americas at Parrot. The device will be available sometime this year, the company said.

WHOT IT’S FOR: ‘Brown-thumbed’ folk and plants with a will to live.

PRICE: Unknown.

—HAPIFORK

If you don’t watch what you put in your mouth, this fork will — or at least try to. Called HAPIfork, it’s a fork with a fat handle containing electronics and a battery. A motion sensor knows when you are lifting the fork to your mouth. If you’re eating too fast, the fork will vibrate as a warning. The company behind it, HapiLabs, believes that using the fork 60 to 75 times during meals that last 20 to 30 minutes is ideal.

But the fork won’t know how healthy or how big each bite you take will be, so shoveling a plate of arugula will likely be judged as less healthy than slowly putting away a pile of bacon. No word on spoons, yet, or chopsticks.

WHO IT’S FOR? People who eat too fast. Those who want company for their “smart” refrigerator and other kitchen gadgets.

PRICE: HapiLabs is launching a fundraising campaign for the fork in March on the group-fundraising site Kickstarter.com. Participants need to pay $ 99 to get a fork, which is expected to ship around April or May.

— IPOTTY

Toilet training a toddler is no picnic, but iPotty from CTA Digital seeks to make it a little easier by letting parents attach an iPad to it. This way, junior can gape and paw at the iPad while taking care of business in the old-fashioned part of the plastic potty. IPotty will go on sale in March, first on Amazon.com.

There are potty training apps out there that’ll reward toddlers for accomplishing the deed. The company is also examining whether the potty’s attachment can be adapted for other types of tablets, beyond the iPad.

“It’s novel to a lot of people but we’ve gotten great feedback from parents who think it’d be great for training,” said CTA product specialist Camilo Gallardo.

WHO IT’S FOR: Parents at their wit’s end.

PRICE: $ 39.99

—MONDO SPIDER, TITANOBOA

A pair of giant hydraulic and lithium polymer battery controlled beasts from Canadian art organization eatART caught some eyes at the show. A rideable 8-legged creature, Mondo Spider weighs 1,600 pounds and can crawl forward at about 5 miles per hour on battery power for roughly an hour. The 1,200-pound Titanoboa slithers along the ground at an as yet unmeasured speed.

Computer maker Lenovo sponsored the group to show off the inventions at CES.

Hugh Patterson, an engineer who volunteers his time to making the gizmos, said they were made in part to learn more about energy use. One lesson from the snake is that “side winding,” in which the snake corkscrews its way along the ground, is one of the most efficient ways of moving along soft ground, like sand.

Titanoboa was made to match the size of a 50-foot long reptile whose fossilized remains were dated 50 million years ago, when the world was 5 to 6 degrees warmer. The creature was built “to provoke discussion about climate change,” Patterson said.

The original version of Mondo Spider, meanwhile, first appeared at the Burning Man arts gathering in Nevada in 2006.

WHO IT’S FOR: Your inner child, Burning Man participants, people with extra-large living rooms.

PRICE: The spider’s parts cost $ 26,000. The Titanoboa costs $ 70,000. Engineers provided their time for free and both took “thousands of hours” to build, Patterson said.

“Homeland,” “Girls” win Directors Guild TV nominations

LOS ANGELES (Reuters) – The directors of hit television dramas “Homeland” and “Mad Men” were among those nominated for Directors Guild of America (DGA) awards on Wednesday.

They were joined by Lena Dunham for her coming-of-age HBO series “Girls” and actor Bryan Cranston for ABC’s “Modern Family” in the comedy category.

AMC’s “Breaking Bad” director Rian Johnson and Greg Mottola, director of HBO’s “The Newsroom,” rounded out the drama category, in which network television series were shut out.

Showtime’s terrorist-hunting thriller “Homeland” scored nominations for two separate episodes – one directed by Michael Cuesta and another by Lesli Linka Glatter.

Jennifer Getzinger garnered a nomination for boozy workplace period drama “Mad Men” on AMC.

The DGA honors the directors of individual episodes of TV shows, unlike the Emmy and Golden Globe awards that honor series as a whole.

Cranston, star of “Breaking Bad,” received his first DGA award nomination. Mark Cendrowski drew honors for geeky CBS comedy “The Big Bang Theory” and comedian Louis C.K. for his FX show “Louie.”

Beth McCarthy-Miller, a two-time DGA winner for her television work, was nominated for Tina Fey’s NBC comedy “30 Rock,” which will finish up its seven-season run on January 31.

Previous DGA winner Jay Roach will compete again in the television movies and mini-series category for the HBO film “Game Change,” a behind-the-scenes drama about John McCain’s and Sarah Palin’s 2008 run for the White House.

The annual DGA Awards, to be hosted by actor Kelsey Grammer in Hollywood on February 2, will also hand out trophies to the directors of movies, children’s TV, commercials, reality shows and documentaries.

AMC is owned by AMC Networks, CBS and Showtime are divisions of CBS Corp, HBO is part of Time Warner Inc, NBC is owned by Comcast Corp, ABC is part of Walt Disney Co and FX is a division of News Corp.

Pap Test May Prove Useful at Detecting More Types of Cancer, Study Suggests

The Pap test, which has prevented countless deaths from cervical cancer, may eventually help to detect cancers of the uterus and ovaries as well, a new study suggests.

For the first time, researchers have found genetic material from uterine or ovarian cancers in Pap smears, meaning that it may become possible to detect three diseases with just one routine test.

But the research is early, years away from being used in medical practice, and there are caveats. The women studied were already known to have cancer, and while the Pap test found 100 percent of the uterine cancers, it detected only 41 percent of the ovarian cancers. And the approach has not yet been tried in women who appear healthy, to determine whether it can find early signs of uterine or ovarian cancer.

On the other hand, even a 41 percent detection rate would be better than the status quo in ovarian cancer, particularly if the detection extends to early stages. The disease is usually advanced by the time it is found, and survival rates are poor. About 22,280 new cases were expected in the United States in 2012, and 15,500 deaths. Improved tests are urgently needed.

Uterine cancer has a better prognosis, but still kills around 8,000 women a year in the United States.

These innovative applications of the Pap test are part of a new era in which advances in genetics are being applied to the detection of a wide variety of cancers or precancerous conditions. Scientists are learning to find minute bits of mutant DNA in tissue samples or bodily fluids that may signal the presence of hidden or incipient cancers.

Ideally, the new techniques would find the abnormalities early enough to cure the disease or even prevent it entirely. But it is too soon to tell.

“Is this the harbinger of things to come? I would answer yes,” said Dr. Bert Vogelstein, director of the Ludwig Center for Cancer Genetics and Therapeutics at Johns Hopkins University, and a senior author of a report on the Pap test study published on Wednesday in the journal Science Translational Medicine. He said the genomes of more than 50 types of tumors had been sequenced, and researchers were trying to take advantage of the information.

Similar studies are under way or are being considered to look for mutant DNA in blood, stool, urine and sputum, both to detect cancer and also to monitor the response to treatment in people known to have the disease.

But researchers warn that such tests, used for screening, can be a double-edged sword if they give false positive results that send patients down a rabbit hole of invasive tests and needless treatments. Even a test that finds only real cancers may be unable to tell aggressive, dangerous ones apart from indolent ones that might never do any harm, leaving patients to decide whether to watch and wait or to go through surgery, chemotherapy and radiation with all the associated risks and side effects.

“Will they start recovering mutations that are not cancer-related?” asked Dr. Christopher P. Crum, a professor at Harvard Medical School who was not involved in the research.

But he also called the study a “great proof of principle,” and said, “Any whisper of hope to women who suffer from endometrial or ovarian cancer would be most welcome.”

DNA testing is already performed on samples from Pap tests, to look for the human papillomavirus, or HPV, which causes cervical cancer. Dr. Vogelstein and his team decided to try DNA testing for cancer. They theorized that cells or DNA shed from cancers of the ovaries and the uterine lining, or endometrium, might reach the cervix and turn up in Pap smears.

The team picked common mutations found in these cancers, and looked for them in tumor samples from 24 women with endometrial cancer and 22 with ovarian cancer. All the cancers had one or more of the common mutations.

Then, the researchers performed Pap tests on the same women, and looked for the same DNA mutations in the Pap specimens. They found the mutations in 100 percent of the women with endometrial cancer, but in only 9 of the 22 with ovarian cancer. The test identified two of the four ovarian cancers that had been diagnosed at an early stage.

Finally, the team developed a test that would look simultaneously for cancer-associated mutations in 12 different genes in Pap samples. Used in a control sample of 14 healthy women, the test found no mutations — meaning no false-positive results.

Dr. Luis A. Diaz, the other senior author of the report and an associate professor of oncology at Johns Hopkins, called the research a step toward a screening test that at first blush appears very effective at detecting endometrial cancer, though obviously less so at finding ovarian cancer.

“Probably one of the most exciting features of this approach,” Dr. Diaz said, “is that we wanted a test that would seamlessly integrate with routine medical practice that could be utilized with the same test that women get every day all over the world, the Pap smear.”

But, he added: “We can’t say it’s ready for prime time. Like all good science, it needs to be validated.”

He and other members of the team said it might be possible to improve the detection rate for ovarian cancer by looking for more mutations and by changing the technique of performing Pap tests to increase the likelihood of capturing cells from the ovary. The change might involve timing the test to a certain point in a woman’s monthly cycle, using a longer brush to collect cells from deeper within the cervix or prescribing a drug that would raise the odds of cells being shed from the ovary.

The technique also needs to be tested in much larger groups of women, including healthy ones, to find out whether it works, particularly at finding cancers early enough to improve survival. And studies must also find out whether it generates false positive results, or identifies cancers that might not actually need to be treated.

Michael H. Melner, a program director in molecular genetics and biochemistry for the American Cancer Society, called the research “very promising,” in part because it is based on finding mutations.

“It tells you not just that cancer is there, but which mutation is there,” Dr. Melner said. “As we learn more and more about which mutations are associated with more or less severe forms of cancer, it’s more information, and possibly more diagnostic.”

Walgreen defends Express Scripts, Alliance Boots moves

Coming off a tumultuous year in which Walgreen lost millions of customers in a contract dispute with a pharmacy benefits manager, executives of the Deerfield-based pharmacy chain sought to reassure shareholders on Wednesday of better days ahead.

At its annual meeting at Navy Pier, Walgreen leaders told a lively crowd of about 2,000 that its new international footprint, a loyalty card and other initiatives, including an enhanced selection of fresh foods and a continued expansion of health care services, have positioned the company for long-term success.

Walgreen Chief Executive Greg Wasson defended its controversial decision a year ago to walk away from a contract with the pharmacy benefit manager Express Scripts Holding Co., whose customers accounted for nearly 11 percent of the total prescriptions Walgreen's filled in 2011. As a result, Walgreen hemorrhaged sales throughout much of the year and its share price tanked.

Shareholders peppered Wasson about the decision, which analysts and others have said could result in the permanent loss of some of its customers.

Nonetheless, Wasson said, "I believe we're a much stronger company today ... it was absolutely the right thing for our shareholders in the long term."

Wasson also faced heat for its decision last June to shell out $6.7 billion for a 45 percent stake in a European pharmacy chain.

Investors sent Walgreen shares down more than 9 percent after the announcement that it would acquire a portion of Alliance Boots GmbH, pushing its stock price below $29, a level not seen for nearly two years.

Michael Pryce-Jones, a senior governance researcher for CtW Investment Group, an activist group that works on behalf of union pension funds, said Walgreen entered into the deal at the wrong time and paid too much.

"The fact is, this is too big a bet going on in a very troubled part of the world," Pryce-Jones said of the deal.

Pryce-Jones implored Walgreen's board to consider bringing the measure to a vote at its 2014 annual meeting, a year before the company is expected to acquire the remaining 55 percent of Alliance Boots.

Walgreen Chief Financial Officer Wade Miquelon said the company conducted "a tremendous amount of due diligence" before agreeing to the pact, which he said remains a "compelling strategic opportunity."

2 shot in strip mall parking lot on Southwest Side

One man was shot to death and another seriously wounded in the Old Town neighborhood this evening, among at least four people shot since this afternoon in the city, authorities said.

A man, age 31, was shot and a man, age 20, was shot in the back in an attack about 6:15 p.m. in the 1300 block of North Sedgwick Avenue.The 31-year-old was taken to Advocate Illinois Masonic Medical Center, where he was declared dead, said Chicago Police News Affairs Officer Daniel O'Brien, citing preliminary information.

The other victim was taken to Northwestern Memorial Hospital in serious-to-critical condition, said Chicago Fire Department spokesman Chief Joe Roccasalva.

The shooting took place in front of a convenience store, police said.

Earlier, two people were shot and seriously wounded, apparently in the parking lot of a small strip mall on the Southwest Side this afternoon, authorities said.

The shooting took place just after 4 p.m. near 65th Street and Western Avenue, said Chicago Police News Affairs Officer Daniel O'Brien. Photos from the scene showed police checking the pavement of a strip mall on the southwest corner of 65th and Western for shell casings following the shooting.

Two men were wounded in the shooting and both were in serious condition, said Chicago Fire Department spokesman Chief Joe Roccasalva. One was taken to Advocate Christ Medical Center in Oak Lawn for treatment, the other to John H. Stroger Jr. Hospital, he said.

On the scene, one victim was shot in the leg was considered in serious condition, and the other man, age 19, shot in the leg, was considered in good condition, O'Brien said.

U.S. Franciscan friars go digital, accept prayer requests via text

NEW YORK (Reuters) – The largest group of Franciscan friars in the United States is offering the faithful a new way to pray in the digital age by accepting prayer requests via text messages.

The Friars of Holy Name Province, who staff 40 parishes and have colleges, soup kitchens and food centers along the eastern seaboard, as well as groups in Peru and Tokyo, are among a few religious groups offering this type of digital service.

Its “Text a Prayer Intention to a Franciscan Friar” initiative, which is described as faith at your fingertips, is a novel way for Roman Catholics to connect.

“People are always saying to friars, ‘Can you say a prayer for me?’ Or ‘Can you remember my mother who has cancer?’” Father David Convertino, the New York-based executive director of development for the Franciscan Friars of the Holy Name Province, said in an interview.

“I was thinking that a lot of people text everything now, even more than email, so why not have people have the ability to ask us to pray for them … by texting.”

The faithful simply text the word ‘prayer’ to 306-44, free of charge. A welcome message from the friars comes up along with a box to type in the request. When the it is sent, the sender receives a reply.

The intentions are received on a website and will be included collectively in the friars’ prayers twice a day and at Mass.

It is one of several ways the friars hope to reach a younger audience, increase the number of faithful and spread the faith. They have already renovated their website and the next step is moving into Facebook and tweeting.

“If the Pope can tweet, friars can text,” said Father David.

The friars also have a presence on LinkedIn and have been streaming some of their church services.

“We’re trying,” said Father David when asked if the friars are well into the digital age, adding that they were “rushing madly into the 19th century.”

Most of the 325 friars, whose average age is about 60, are comfortable with the technology.

“We have a friar who is 80 who was texting today,” said Father David.

The friars are following the example of 85-year-old Pope Benedict, the leader of the world’s 1.2 billion Roman Catholics, whom the Vatican said had 2.1 million followers on Twitter just eight days after sending his first tweet.

The Pontiff tweets in several languages, including Arabic, and plans to add Latin and Chinese to them.

“We’re really excited about this working,” said Father David, about the new program. “I think we’ll be able to keep up (with all the intentions). That’s what we do, we pray for people.”

“Idol” judges Mariah Carey, Nicki Minaj play nice after feud

LOS ANGELES (Reuters) – New “American Idol” judges Mariah Carey and Nicki Minaj shrugged off their widely publicized feud on Tuesday as a “trumped-up thing” that was merely a passionate difference of opinion over the TV talent show‘s contestants.

In their first big media appearance ahead of the hit show’s return to Fox television on January 16, the two pop stars showered each other with praise while barely looking at each other.

A day after the airing of an ABC TV interview in which Carey said she hired extra security following threats reportedly made against her by Minaj last year, the “Hero” singer told reporters it was time to focus on the aspiring “Idol” stars.

“This is a very passionate panel. There are a lot of strong personalities,” said Carey, who is reportedly being paid $ 18 million to be an “American Idol” judge.

“The fighting is what it is. This is ‘American Idol.’ It is bigger than some stupid trumped-up thing. It’s about the next superstar … The whole thing is convoluted. It’s a distraction from the show and the contestants,” Carey said.

Minaj, an outspoken 30-year-old rapper, called Carey one of her “favorite artists of all time.”

“She has really shaped a generation of singers and to be on a panel with her where (contestants) all aspire to be Mariah Carey … I feel excited to see them, see someone they look up to so much,” Minaj said.

Carey, 42, recalled working with Minaj in 2009 on an album track, and knowing at the time that the rapper would be successful.

“Nothing to write about now!” quipped “American Idol” host Ryan Seacrest.

REVIVING AGING ‘IDOL’ FORMAT

Carey, Minaj and country singer Keith Urban joined “Idol” as judges in September for the upcoming 12th season after the departures of Jennifer Lopez and Aerosmith frontman Steven Tyler.

Carey, with more than 200 million album sales, and Minaj, one of the most exciting voices in rap, are expected to revive the contest, which last year lost its eight-year crown as the most-watched show on U.S. television to “Saturday Night Football” on rival NBC.

Video of the pair arguing was leaked online from early auditions in last fall, and Minaj was reported to have said, “If I had a gun, I would shoot that bitch.”

“American Idol” executive producer Trish Kinane said the new panel was chosen after fans said they wanted to see judges who were current and talented in their own right.

“They (fans) also wanted honesty, and we very much took that into consideration. They (the judges) are not shrinking violets. They say what they think, and we encourage that,” Kinane said.

“American Idol“, which has produced stars like Kelly Clarkson and Carrie Underwood, faces growing competition for TV audiences from a slew of rivals like “The Voice,” “The X Factor,” and “America’s Got Talent.” Last year, “Idol” attracted under 20 million viewers, down from the more than 30 million who watched on a regular basis five or six years ago.

But Mike Darnell, reality programming chief for Fox, said the new panel had “re-invigorated the show.”

“Yes, there are too many (talent) shows on the air and they are all taking each other down a bit. But this is still the king of the shows and the only one that makes stars,” Darnell said.

Fox is a unit of News Corp.

Gaps Seen in Therapy for Suicidal Teenagers

Most adolescents who plan or attempt suicide have already received at least some mental health treatment, raising questions about the effectiveness of current approaches to helping troubled youths, according to the largest in-depth analysis to date of suicidal behaviors in American teenagers.

The study, in the journal JAMA Psychiatry, found that 55 percent of suicidal teenagers had received some therapy before they thought about suicide, planned it or tried to kill themselves, contradicting the widely held belief that suicide is due in part to a lack of access to treatment.

The findings, based on interviews with a nationwide sample of more than 6,000 teenagers and at least one parent of each, linked suicidal behavior to complex combinations of mood disorders like depression and behavior problems like attention-deficit and eating disorders, as well as alcohol and drug abuse.

The study found that about one in eight teenagers had persistent suicidal thoughts at some point, and that about a third of those who had suicidal thoughts had made an attempt, usually within a year of having the idea.

Previous studies have had similar findings, based on smaller, regional samples. But the new study is the first to suggest, in a large nationwide sample, that access to treatment does not make a big difference.

The study suggests that effective treatment for severely suicidal teenagers must address not just mood disorders, but also behavior problems that can lead to impulsive acts, experts said. According to the Centers for Disease Control and Prevention, 1,386 people between the ages of 13 and 18 committed suicide in 2010, the latest year for which numbers are available.

“I think one of the take-aways here is that treatment for depression may be necessary but not sufficient to prevent kids from attempting suicide,” said Dr. David Brent, a professor of psychiatry at the University of Pittsburgh, who was not involved in the study. “We simply do not have empirically validated treatments for recurrent suicidal behavior.”

The report said nothing about whether the therapies given were state of the art or carefully done, said Matt Nock, a professor of psychology at Harvard and the lead author, and it is possible that some of the treatments prevented suicide attempts. “But it’s telling us we’ve got a long way to go to do this right,” Dr. Nock said. His co-authors included Ronald C. Kessler of Harvard and researchers from Boston University and Children’s Hospital Boston.

Margaret McConnell, a consultant in Alexandria, Va., said her daughter Alice, who killed herself in 2006 at the age of 17, was getting treatment at the time. “I think there might have been some carelessness in the way the treatment was done,” Ms. McConnell said, “and I was trusting a 17-year-old to manage her own medication. We found out after we lost her that she wasn’t taking it regularly.”

In the study, researchers surveyed 6,483 adolescents from the ages of 13 to 18 and found that 9 percent of male teenagers and 15 percent of female teenagers experienced some stretch of having persistent suicidal thoughts. Among girls, 5 percent made suicide plans and 6 percent made at least one attempt (some were unplanned).

Among boys, 3 percent made plans and 2 percent carried out attempts, which tended to be more lethal than girls’ attempts.

(Suicidal thinking or behavior was virtually unheard-of before age 10.)

Over all, about one-third of teenagers with persistent suicidal thoughts went on to make an attempt to take their own lives.

Almost all of the suicidal adolescents in the study qualified for some psychiatric diagnosis, whether depression, phobias or generalized anxiety disorder. Those with an added behavior problem — attention-deficit disorder, substance abuse, explosive anger — were more likely to act on thoughts of self-harm, the study found.

Doctors have tested a range of therapies to prevent or reduce recurrent suicidal behaviors, with mixed success. Medications can ease depression, but in some cases they can increase suicidal thinking. Talk therapy can contain some behavior problems, but not all.

One approach, called dialectical behavior therapy, has proved effective in reducing hospitalizations and suicide attempts in, among others, people with borderline personality disorder, who are highly prone to self-harm.

But suicidal teenagers who have a mixture of mood and behavior issues are difficult to reach. In one 2011 study, researchers at George Mason University reduced suicide attempts, hospitalizations, drinking and drug use among suicidal adolescent substance abusers. The study found that a combination of intensive treatments — talk therapy for mood problems, family-based therapy for behavior issues and patient-led reduction in drug use — was more effective than regular therapies.

“But that’s just one study, and it’s small,” said Dr. Brent of the University of Pittsburgh. “We can treat components of the overall problem, but that’s about all.”

Ms. McConnell said that her daughter’s depression had seemed mild and that there was no warning that she would take her life. “I think therapy does help a lot of people, if it’s handled right,” she said.

Dreamliner glitches giving Boeing a black eye

Boeing's 787 Dreamliner could become a public relations nightmare for Chicago-based Boeing Co. and some of its airline customers.

Electrical problems and fuel leaks have plagued the new Boeing plane model recently. On Monday, an empty Japan Airlines 787 in Boston caught fire. On Tuesday, a fuel leak forced a different Japan Airlines 787 to cancel takeoff and return to the gate before ultimately completing its trip to Tokyo.

"We're getting to a tipping point, where they go from needing to rectify problems to doing major damage control to the image of the company and the plane," said Richard Aboulafia, a defense and aerospace analyst with Teal Group, a consulting firm based in Fairfax, Va. "While they delivered a large and unexpected number of 787s last year, it's possible that they should have instead focused on identifying glitches and flaws, rather than pushing ahead with volume production."

The fire, in particular, prompted Chicago-based United Airlines — it's the only North American carrier so far to operate 787s — to inspect its six new Boeing 787 airplanes overnight.

United reportedly found improperly installed wires in one plane's auxiliary power unit, the same system involved in the Japan Airlines electrical fire Monday, said The Wall Street Journal, citing an unnamed source.

But United would not confirm that finding.

"We continue to work closely with Boeing on the reliability of our 787s," United spokeswoman Mary Ryan said.

The rash of recent incidents, including those this week and inspections for fuel leaks ordered by the Federal Aviation Administration last month, add to the problems of Boeing, which had already endured criticism for delivering 787s to customers more than three years late because of design and production problems.

Investors were not pleased. Boeing's stock price dropped 2 percent Monday and an additional 2.6 percent Tuesday.

Boeing said in a statement it was premature to discuss details of Monday's fire but "nothing that we've seen in this case indicates a relationship to any previous 787 power system events."

Boeing said it is cooperating with the National Transportation Safety Board in investigating the fire, which was discovered when Japan Airlines reported smoke coming from the 787 at Boston's Logan International Airport, where passengers had disembarked and the plane was being cleaned. The fire was traced to the battery used to start the auxiliary power unit.

"Before providing more detail, we will give our technical teams the time they need to do a thorough job and ensure we are dealing with facts, not speculation," Boeing said.

Aviation experts say glitches are to be expected early in an aircraft's life cycle, especially one as revolutionary as the 787. The highly anticipated Dreamliner is touted as offering greater passenger comforts and fuel efficiency, largely because of its construction of light composite materials rather than metals.

"These types of issues are not uncommon," said Timothy O'Neil-Dunne, managing partner of aviation and travel consulting firm T2Impact. "The electrical (systems) on a 787 are incredibly complex." He cited early production problems with other aircraft models, including the Airbus A380, "when they basically had to rewire the whole plane."

"I won't want people to rush to conclusions that the aircraft is not safe," he said. "However, the level of complexity and the early production problems suffered by Boeing … reflects on the company's eagerness to ramp up production to a very fast rate."

Aboulafia said there is no indication the plane itself is flawed.

"It's just a question of how quickly they can get all the onboard technologies right, and whether or not the 787 and Boeing brands will be badly damaged," he said.
