Robotic Autobot Transformer Shows Other 3D-Printed Gear Who's Boss

Forget scale models of the Aston Martin DB5 or personalized action figures. This is what 3D printers were meant to do: create real, robotic Transformers.

Or at least a version of a Transformer that would actually fit in your living room.

Brave Robotics developed a 1/12 scale Autobot transformer using a custom 3D printer, and it will be on display at Maker Faire Tokyo next week. Once fully morphed out of its initial automobile form, it takes the shape of a bipedal robot that moves about much like two-legged soccer-playing robots we’ve seen at Robocup and Robogames. This robot also has the ability to shoot some sort of dart from each of its arms.

A fully assembled and programed mini-Autobot, complete with remote control and housed in its own case, will be available for purchase, but a price has not yet been disclosed. Production is limited to 10 units, but you can choose the colors of your Decepticon fighting robot. Once you’ve placed your order, it’ll take about a month to produce.

Check out this Earth-defending, shape-shifting robot in action below.

Rihanna’s “Unapologetic” tops Billboard album chart

LOS ANGELES (Reuters) – R&B singer Rihanna shot straight to the top of the Billboard 200 album chart on Tuesday with her seventh record “Unapologetic,” scoring her first No. 1 album despite mixed reviews.

“Unapologetic,” which topped iTunes charts in 43 countries just hours after its release on November19, sold 238,000 copies according to Billboard, scoring the 24-year-old singer from Barbados her best opening sales week to date.

The album’s lead single “Diamonds” landed at the top of the Billboard Hot 100 chart last week, giving Rihanna her 12th No. 1 single and tying her with Madonna and The Supremes for the fourth-most chart-topping singles in Billboard history.

“Unapologetic” left some critics unsettled by the singer’s harder sound and close-to-home lyrics. One track in particular that had everyone talking is “Nobody’s Business,” Rihanna’s collaboration with ex-boyfriend Chris Brown, who was charged with assaulting her three years ago.

The album has been promoted extensively by Rihanna, who embarked on a seven day tour across seven cities around the world, accompanied by a plane full of fans and journalists.

The full Billboard charts will be released on Wednesday.

The New Old Age Blog: Doctor's Orders? Another Test

It is no longer news that Americans, and older Americans in particular, get more routine screening tests than they need, more than are useful. Prostate tests for men over 75, annual Pap smears for women over 65 and colonoscopies for anyone over 75 — all are overused, large-scale studies have shown.

Now it appears that many older patients are also subjected to too-frequent use of the other kind of testing, diagnostic tests.

The difference, in brief: Screening tests are performed on people who are asymptomatic, who aren’t complaining of a health problem, as a way to detect incipient disease. We have heard for years that it is best to “catch it early” — “it” frequently being cancer — and though that turns out to be only sometimes true, we and our doctors often ignore medical guidelines and ongoing campaigns to limit and target screening tests.

Diagnostic tests, on the other hand, are meant to help doctors evaluate some symptom or problem. “You’re trying to figure out what’s wrong,” explained Gilbert Welch, a veteran researcher at the Dartmouth Institute for Health Policy and Clinical Practice.

For these tests, medical groups and task forces offer many fewer guidelines on who should get them and how often — there is not much evidence to go on — but there is general agreement that they are not intended for routine surveillance.

But a study using a random 5 percent sample of Medicare beneficiaries — nearly 750,000 of them — suggests that often, that is what’s happening.

“It begins to look like some of these tests are being routinely repeated, and it’s worrisome,” said Dr. Welch, lead author of the study just published in The Archives of Internal Medicine. “Some physicians are just doing them every year.”

He is talking about tests like echocardiography, or a sonogram of the heart. More than a quarter of the sample (28.5 percent) underwent this test between 2004 and 2006, and more than half of those patients (55 percent) had a repeat echocardiogram within three years, most commonly within a year of the first.

Other common tests were frequently repeated as well. Of patients who underwent an imaging stress test, using a treadmill or stationery bike (or receiving a drug) to make the heart work harder, nearly 44 percent had a repeat test within three years. So did about half of those undergoing pulmonary function tests and chest tomography, a CAT scan of the chest.

Cytoscopy (a procedure in which a viewing tube is inserted into the bladder) was repeated for about 41 percent of the patients, and endoscopy (a swallowed tube enters the esophagus and stomach) for more than a third.

Is this too much testing? Without evidence of how much it harms or helps patients, it is hard to say — but the researchers were startled by the extent of repetition. “It’s inconceivable that it’s all important,” Dr. Welch said. “Unfortunately, it looks like it’s important for doctors.”

The evidence for that? The study revealed big geographic differences in diagnostic testing. Looking at the country’s 50 largest metropolitan areas, it found that nearly half the sample’s patients in Miami had an echocardiogram between 2004 and 2006, and two thirds of them had another echocardiogram within three years — the highest rate in the nation.

In fact, for the six tests the study included, five were performed and repeated most often in Florida cities: Miami, Jacksonville and Orlando. “They’re heavily populated by physicians and they have a long history of being at the top of the list” of areas that do a lot of medical procedures and hospitalizations, Dr. Welch said.

But in Portland, Ore., where “the physician culture is very different,” only 17.5 percent of patients had an echocardiogram. The places most prone to testing were also the places with high rates of repeat testing. Portland, San Francisco and Sacramento had the lowest rates.

We often don’t think of tests as having a downside, but they do. “This is the way whole cascades can start that are hard to stop,” Dr. Welch said. “The more we subject ourselves, the more likely some abnormality shows up that may require more testing, some of which has unwanted consequences.”

Properly used, of course, diagnostic tests can provide crucial information for sick people. “But used without a good indication, they can stir up a hornet’s nest,” he said. And of course they cost Medicare a bundle.

An accompanying commentary, sounding distinctly exasperated, pointed out that efforts to restrain overtesting and overtreatment have continued for decades. The commentary called it “discouraging to contemplate fresh evidence by Welch et al of our failure to curb waste of health care resources.”

It is hard for laypeople to know when tests make sense, but clearly we need to keep track of those we and our family members have. That way, if the cardiologist suggests another echocardiogram, we can at least ask a few pointed questions:

“My father just had one six months ago. Is it necessary to have another so soon? What information do you hope to gain that you didn’t have last time? Will the results change the way we manage his condition?”

Questions are always a good idea. Especially in Florida.

Ex-NASA Scientist’s Data Fears Come True

In 2007, Robert M. Nelson, an astronomer, and 27 other scientists at the Jet Propulsion Laboratory sued NASA arguing that the space agency’s background checks of employees of government contractors were unnecessarily invasive and violated their privacy rights.

Privacy advocates chimed in as well, contending that the space agency would not be able to protect the confidential details it was collecting.

The scientists took their case all the way to the Supreme Court only to lose last year.

This month, Dr. Nelson opened a letter from NASA telling him of a significant data breach that could potentially expose him to identity theft.

The very thing he and advocates worried about had occurred. A laptop used by an employee at NASA’s headquarters in Washington had been stolen from a car parked on the street on Halloween, the space agency said.

Although the laptop itself was password protected, unencrypted files on the laptop contained personal information on about 10,000 NASA employees — including details like their names, birth dates, Social Security numbers and in some cases, details related to background checks into employees’ personal lives.

Millions of Americans have received similar data breach notices from employers, government agencies, medical centers, banks and retailers. NASA in particular has been subject to “numerous cyberattacks” and computer thefts in recent years, according to a report from the Government Accountability Office, an agency that conducts research for Congress.

Even so, Dr. Nelson, who recently retired from the Jet Propulsion Laboratory, a research facility operated by the California Institute of Technology under a contract with NASA, stands out as a glaring example of security lapses involving personal data, privacy advocates say.

“To the extent that Robert Nelson looks like millions of other people working for firms employed by the federal government, this would seem to be a real problem,” said Marc Rotenberg, the executive director of the Electronic Privacy Information Center, an advocacy group which filed a friend-of-the-court brief for Dr. Nelson in the Supreme Court case.

In a 2009 report titled “NASA Needs to Remedy Vulnerabilities in Key Networks,” the Government Accountability Office noted that the agency had reported 1,120 security incidents in fiscal 2007 and 2008 alone.

It also singled out an incident in 2009 in which a NASA center reported the theft of a laptop containing about 3,000 unencrypted files about arms traffic regulations and wind tunnel tests for a supersonic jet.

“NASA had not installed full-disk encryption on its laptops at all three centers,” the report said. “As a result, sensitive data transmitted through the unclassified network or stored on laptop computers were at an increased risk of being compromised.” Other federal agencies have had similar problems. In 2006, for example, the Department of Veteran’s Affairs reported the theft of an employee laptop and hard drive that contained personal details on about 26.5 million veterans. Last year, the G.A.O. cited the Internal Revenue Service for weaknesses in data control that could “jeopardize the confidentiality, integrity, and availability of financial and sensitive taxpayer information.”

Also last year, the Securities and Exchange Commission warned its employees that their confidential financial information, like brokerage transactions, might have been compromised because an agency contractor had granted data access to a subcontractor without the S.E.C.’s authorization.

In a phone interview, Dr. Nelson, the astronomer, said he planned to hold a news conference on Wednesday morning in which he would ask members of Congress to investigate NASA’s data collection practices and the recent data breach.

Robert Jacobs, a NASA spokesman, said the agency’s data security policy already adequately protected employees and contractors because it required computers to be encrypted before employees took them off agency premises. “We are talking about a computer that should not have left the building in the first place,” Mr. Jacobs said. “The data would have been secure had the employee followed policy.”

The government argued in the case Dr. Nelson filed that a law called the Privacy Act, which governs data collection by federal agencies, provided the scientists with sufficient protection. The case reached the Supreme Court, which upheld government background checks for employees of contractors. The roots of Dr. Nelson’s case against NASA date back to 2004 when the Department of Homeland Security, under a directive signed by President George Bush, required federal agencies to adopt uniform identification credentials for all civil servants and contract employees. As part of the ID card standardization process, the department recommended agencies institute background checks.

Several years later, when NASA announced it intended to start doing background checks at the Jet Propulsion Laboratory, Dr. Nelson and other scientists there objected.

Those security checks could have included inquiries into medical treatment, counseling for drug use, or any “adverse” information about employees such as sexual activity, or participation in protests, said Dan Stormer, a lawyer representing Dr. Nelson.

But Dr. Nelson and other long-term employees of the lab challenged the legality of those checks, arguing that they violated their privacy rights. NASA, they said, had not established a legitimate need for such extensive investigations about low-risk employees like themselves who did not have security clearances or handle confidential information. Dr. Nelson, for example, specializes in solar system science — concerning, for example, Jupiter’s moon Io and Titan, a moon of Saturn — and publishes his work in scientific journals

“It was an invitation to an open-ended fishing expedition,” Dr. Nelson said of the background checks.

In friend of the court briefs for Dr. Nelson, privacy groups cited many data security problems at federal agencies, arguing that there was a risk that NASA was not equipped to protect the confidential details it was collecting about employees and contractors.

In 2008, the United States Court of Appeals for the Ninth Circuit in San Francisco temporarily halted the background checks, saying that the case had raised important questions about privacy rights. But last year, the Supreme Court upheld the background investigations of employees of government contractors.

Dr. Nelson said he retired from the Jet Propulsion Laboratory last June rather than submit to a background check. He now works as a senior scientist at the Planetary Science Institute of Tucson.

NASA has contracted with ID Experts, a data breach company, to help protect employees whose data was contained on the stolen laptop against identity theft. Mr. Jacobs, the NASA spokesman, said the agency has encrypted almost 80 percent of its laptops and plans to encrypt the rest by Dec. 21. He added that he too received a letter from NASA warning that his personal information might have been compromised by the laptop theft.

Former baseball union head Miller dead at 95

Marvin Miller, the union leader who created free agency for baseball players and revolutionized professional sports with multimillion dollar contracts, died Tuesday. He was 95.

Miller died at his home in Manhattan at 5:30 a.m., said his daughter Susan Miller. He had been diagnosed with liver cancer in August.

In his 16 years as executive director of the Major League Players Association, starting in 1966, Miller fought owners on many fronts, winning free agency for the players in December 1975. He may best be remembered, however, as the man who made the word "strike" stand for something other than a pitched ball.

Miller, who retired and became a consultant to the union in 1982, led the first walkout in the game's history 10 years earlier. On April 5, 1972, signs posted at major league parks simply said "No Game Today." The strike, which lasted 13 days, was to be followed by a walkout during spring training in 1976 and a midseason job action that darkened the stadiums for seven weeks in 1981.

Miller's ascension to the top echelon among sports labor leaders was by no means free from controversy among those he would represent. Players from the Los Angeles Dodgers, Atlanta Braves, California Angels and San Francisco Giants opposed his appointment as successor to Milwaukee Circuit Court Judge Robert Cannon, who had counseled them on a part-time but unpaid basis.

Miller overcame the opposition, however, due in part to his demeanor.

"Some of the player representatives were leery about picking a union man," Hall of Fame pitcher and U.S. Senator Jim Bunning, a member of the screening committee that recommended Miller, recalled in a 1974 interview. "But he was very articulate ... not the cigar-chewing type some of the guys expected."

Munich Subway Photos Resemble Abandoned Kubrickian Spacecraft

Nick Frank likes to summarize his approach to photography with one phrase: “Reduce to the max.”

Get to the point. Remove all distractions. It’s a framework that lends itself well to Frank’s series on subway stations in Munich, Germany, where he lives.

“Pictures are often overloaded with information so what I’m doing is trying to flatten the image until you see the essence of the main subject,” he says.

The Munich subway, or U-Bahn, began running in 1971 right before the 1972 Olympics and is known for the bright color schemes and artistic designs that line many of the subway’s 100 stations. In a 1997 book by Christoph Hackelsberger, a member of the city’s subway planning council is quoted as saying that transit stations should “radiate a positive mood” and purposefully “help make a passenger’s wait more pleasant.”

Many of the stations are designed by well-known German architects and the subways themselves are used by hundreds of millions of people each year.

To avoid the crowds and get the kind of clean, empty shots that make up the series, Frank says he has to show up between 5:30 and 6 a.m. on a Sunday morning because that’s the only time the subways aren’t packed. Even then, he says he only has about an hour before things get busy.

Frank is also not shy about using Photoshop to clean things up even further. The gist of the photo is still present, but he’s not afraid to remove trash from the floors or cut a stray person from the background, all with the end goal of trying to create the kind of singular focus that makes his photos pop.

“My photos are not about reality,” he says. “It’s about what I’m seeing.”

He says he was originally drawn to subways not only because many of them are architecturally interesting but also because they tend to be places of creativity. Like many people who ride the trains to work, Frank says he does some of his best thinking on his morning and afternoon commute.

“You usually use the time in the subway to reflect on your day,” he says. “It’s not about talking to other people, it’s all about yourself. Most of my advertising ideas are developed in the subway.”

He hopes his photos, with their sharp lines, symmetry and clear focus, help people call up a similar visceral experience to the one they have while on the trains.

“I want to transport you back,” he says.

Frank will be starting a Kickstarter campaing to fund more subway shoots around the globe so please check his website in early December for more information

New Jersey’s Christie, more popular than ever, seeks re-election

NEW YORK (Reuters) – New Jersey Governor Chris Christie, a Republican star who has enjoying record-high popularity for his hands-on approach to Superstorm Sandy, on Monday filed papers announcing his intention to seek a second term next November.

Christie, a popular surrogate on Republican Mitt Romney‘s failed presidential campaign, delivered the keynote address at the Republican National Convention this summer and is considered a popular choice to run for president in 2016.

Despite his popularity on the national stage, Christie – known for his blunt, sometimes over-the-top style – has sometimes struggled to win over his constituents in liberal New Jersey, where Democrats control both houses of the legislature.

Since Sandy tore through the state on October 29, laying waste to large stretches of the Jersey Shore, Christie’s approval rating has jumped 19 percentage points.

Christie appeared to set politics aside, touring the damage with Democratic President Barack Obama days before November 6 Election Day, and showing a personal touch with residents who lost their homes or loved ones in the storm.

Christie has a 67 percent favorability rating among registered voters, up from 48 percent in October, according to the Rutgers-Eagleton poll.

Since taking office three years ago, Christie’s signature achievement has been a 2011 law that made sweeping changes to the state’s pensions and health benefits for state workers.

Clearing the Fog Around Personality Disorders

For years they have lived as orphans and outliers, a colony of misfit characters on their own island: the bizarre one and the needy one, the untrusting and the crooked, the grandiose and the cowardly.

Their customs and rituals are as captivating as any tribe’s, and at least as mystifying. Every mental anthropologist who has visited their world seems to walk away with a different story, a new model to explain those strange behaviors.

This weekend the Board of Trustees of the American Psychiatric Association will vote on whether to adopt a new diagnostic system for some of the most serious, and striking, syndromes in medicine: personality disorders.

Personality disorders occupy a troublesome niche in psychiatry. The 10 recognized syndromes are fairly well represented on the self-help shelves of bookstores and include such well-known types as narcissistic personality disorder, avoidant personality disorder, as well as dependent and histrionic personalities.

But when full-blown, the disorders are difficult to characterize and treat, and doctors seldom do careful evaluations, missing or downplaying behavior patterns that underlie problems like depression and anxiety in millions of people.

The new proposal — part of the psychiatric association’s effort of many years to update its influential diagnostic manual — is intended to clarify these diagnoses and better integrate them into clinical practice, to extend and improve treatment. But the effort has run into so much opposition that it will probably be relegated to the back of the manual, if it’s allowed in at all.

Dr. David J. Kupfer, a professor of psychiatry at the University of Pittsburgh and chairman of the task force updating the manual, would not speculate on which way the vote might go: “All I can say is that personality disorders were one of the first things we tackled, but that doesn’t make it the easiest.”

The entire exercise has forced psychiatrists to confront one of the field’s most elementary, yet still unresolved, questions: What, exactly, is a personality problem?

Habits of Thought

It wasn’t supposed to be this difficult.

Personality problems aren’t exactly new or hidden. They play out in Greek mythology, from Narcissus to the sadistic Ares. They percolate through biblical stories of madmen, compulsives and charismatics. They are writ large across the 20th century, with its rogues’ gallery of vainglorious, murderous dictators.

Yet it turns out that producing precise, lasting definitions of extreme behavior patterns is exhausting work. It took more than a decade of observing patients before the German psychiatrist Emil Kraepelin could draw a clear line between psychotic disorders, like schizophrenia, and mood problems, like depression or bipolar disorder.

Likewise, Freud spent years formulating his theories on the origins of neurotic syndromes. And Freudian analysts were largely the ones who, in the early decades of the last century, described people with the sort of “confounded identities” that are now considered personality disorders.

Their problems were not periodic symptoms, like moodiness or panic attacks, but issues rooted in longstanding habits of thought and feeling — in who they were.

“These therapists saw people coming into treatment who looked well put-together on the surface but on the couch became very disorganized, very impaired,” said Mark F. Lenzenweger, a professor of psychology at the State University of New York at Binghamton. “They had problems that were neither psychotic nor neurotic. They represented something else altogether.”

Several prototypes soon began to emerge. “A pedantic sense of order is typical of the compulsive character,” wrote the Freudian analyst Wilhelm Reich in his 1933 book, “Character Analysis,” a groundbreaking text. “In both big and small things, he lives his life according to a preconceived, irrevocable pattern.”

Others coalesced too, most recognizable as extreme forms of everyday types: the narcissist, with his fragile, grandiose self-approval; the dependent, with her smothering clinginess; the histrionic, always in the thick of some drama, desperate to be the center of attention.

In the late 1970s, Ted Millon, scientific director of the Institute for Advanced Studies in Personology and Psychopathology, pulled together the bulk of the work on personality disorders, most of it descriptive, and turned it into a set of 10 standardized types for the American Psychiatric Association’s third diagnostic manual. Published in 1980, it is a best seller among mental health workers worldwide.

These diagnostic criteria held up well for years and led to improved treatments for some people, like those with borderline personality disorder. Borderline is characterized by an extreme neediness and urges to harm oneself, often including thoughts of suicide. Many who seek help for depression also turn out to have borderline patterns, making their mood problems resistant to the usual therapies, like antidepressant drugs.

Today there are several approaches that can relieve borderline symptoms and one that, in numerous studies, has reduced hospitalizations and helped aid recovery: dialectical behavior therapy.

This progress notwithstanding, many in the field began to argue that the diagnostic catalog needed a rewrite. For one thing, some of the categories overlapped, and troubled people often got two or more personality diagnoses. “Personality Disorder-Not Otherwise Specified,” a catchall label meaning little more than “this person has problems” became the most common of the diagnoses.

It’s a murky area, and in recent years many therapists didn’t have the time or training to evaluate personality on top of everything else. The assessment interviews can last hours, and treatments for most of the disorders involve longer-term, specialized talk therapy.

Psychiatry was failing the sort of patients that no other field could possibly help, many experts said.

“The diagnoses simply weren’t being used very much, and there was a real need to make the whole system much more accessible,” Dr. Lenzenweger said.

Resisting Simplification 

It was easier said than done.

The most central, memorable, and knowable element of any person — personality — still defies any consensus.

A team of experts appointed by the psychiatric association has worked for more than five years to find some unifying system of diagnosis for personality problems.

The panel proposed a system based in part on a failure to “develop a coherent sense of self or identity.” Not good enough, some psychiatric theorists said.

Later, the experts tied elements of the disorders to distortions in basic traits.

News Analysis: St. Jude Medical Suffers for Redacting a Product Name

Peter Muhly for The New York Times

Dr. Ernest Lau holds a Durata lead from a St. Jude Medical Fortify ICD, an implanted heart defibrillator.

IS covering a product’s name in a public document a sign that a company has something to hide? And how should doctors, patients and investors react if the product at issue is one on which peoples’ lives and a company’s fortunes depend?

Such questions now loom over St. Jude Medical after the disclosure last week that its executives had blacked out the name of a heart device component when they released a critical federal report involving the product. The value of St. Jude has since plummeted more than $1 billion, or 12 percent. But the company’s actions may have a more lasting impact on its reputation and the health of patients, some experts say.

Last week’s incident was the latest development in a controversy involving the component, an electrical wire that connects an implanted defibrillator to a patient’s heart. St. Jude officials say the wire, which is known as the Durata, is safe. But uncertainty about the company’s statements is growing, underscored by its handling of the report, which involved a Food and Drug Administration inspection of a plant that makes the Durata.

St. Jude released that report in October as part of a filing with the Securities and Exchange Commission. The F.D.A. provides device makers with the reports in an unaltered form, and they may contain criticisms of a company’s procedures.

But the version of the report that St. Jude filed with the S.E.C. left some doctors and analysts uncertain about which company product or products were at issue for a simple reason — St. Jude had redacted, or blocked out, all 20 references to the Durata in it.

Company executives said they had done so based on their “good faith” interpretation of how the F.D.A. would act if it publicly released the report under the Freedom of Information Act. But both an F.D.A spokeswoman and a lawyer who specializes in medical devices took exception with that view, saying that names of approved products typically do not qualify as the type of confidential business information that the F.D.A. would redact.

Among other things, F.D.A. inspectors found significant flaws in the company’s testing and oversight of the Durata. It was those revelations and the implications that the problems could lead to further F.D.A. action against St. Jude that led to the sharp fall last week in its stock price.

In 2005, Guidant, a device maker that no longer exists, also found itself under scrutiny. Back then, its executives decided not to tell doctors that one of its defibrillators could short-circuit when a patient needed an electrical jolt to save a life. The expert who brought the Guidant problem to light, Dr. Robert Hauser, a heart specialist in Minnesota, has also raised concerns about the St. Jude wires, adding that he believes that its executives have been less than forthright.

“Patients and physicians would appreciate more information,” Dr. Hauser said.

In an earlier interview, St. Jude’s chief executive, Daniel J. Starks, said the company had hidden nothing about the Durata or another heart wire named the Riata, which it stopped selling in 2010.

“We’ve been more transparent than others,” said Mr. Starks, referring to company competitors like Medtronic.

Still, some Wall Street analysts share Dr. Hauser’s view. And if one St. Jude executive can claim credit for shaping their opinion, it would be Mr. Starks.

Earlier this year, he sought, among other things, to have a medical journal retract an article written by Dr. Hauser that was critical of the Riata. The publication refused.

Now, after St. Jude’s latest misfire, Wall Street analysts, who usually agree more than disagree, are placing wildly differing bets on St. Jude, with some valuing it at $48 a share and others at $30. On Monday, St. Jude closed at $31.86 on the New York Stock Exchange.

One of those bearish analysts, Matthew Dodds of Citigroup, said he thought the Food and Drug Administration might act soon on Durata. “I believe that a lot of their actions have made the situation worse, ” he said of the company’s executives.

A St. Jude spokeswoman, Amy Jo Meyer, reiterated the company’s stance that it had interpreted agency rules in “good faith” when releasing the redacted report about the Durata. An F.D.A. spokeswoman, Mary Long, said the agency did not consider the names of approved products to be confidential. And a lawyer, William Vodra, said that while device makers try to make a confidentiality argument for product data they consider embarrassing, like injury reports, they rarely succeed.

“In my experience, the F.D.A. consistently rejects” such arguments, Mr. Vodra wrote in an e-mail.

For patients, the dilemma may become more excruciating. The company’s earlier heart wire, the Riata, has begun failing prematurely in some of the 128,000 patients worldwide who received it. And those patients and their doctors face a difficult decision: whether to leave it in place or have it surgically removed, a procedure that carries significant risks.

St. Jude executives say that the Durata, which uses a different type of insulation than the Riata, is not prone to such problems.

And with the Durata already implanted in 278,000 people, many heart specialists certainly hope they are right.

Sex, love, surrogacy and 'Sessions'

BERKELEY, Calif. — Cheryl Cohen Greene likes to spend weekends close to home with her husband, Bob, a former postal worker. Often, they go hiking in the Berkeley Hills that surround their neighborhood, or watch movies in the living room of their modest duplex.

At 68, Greene is trim for her age and says she'd lose 10 pounds if she didn't love food so much. She's a devoted grandmother who frequently visits with her two children and grandchildren.

No one would guess that more than 900 people have paid to have sex with her.

Greene has worked as a surrogate partner therapist for 40 years. During one-on-one sessions at her home, which doubles as an office, she uses sensual touch to guide those who struggle with sex and intimacy issues. She almost always removes her clothes. And — yes — she sleeps with her patients. In the bed, by the way, that she shares with her spouse.

VIDEO | The Envelope Screening Series: 'The Sessions'

"For a long time, I didn't bring it up at cocktail parties," says Greene, who keeps hand-carved wooden statues of genitalia in the nooks and crannies of her home. A close look at her bookshelves reveals "The Guide to Getting It On" and hundreds of other sex-related titles, along with "Calorie Counting" and "The Big Book of Jewish Humor." A big Tupperware container labeled "Cheryl's Vitamins" rests on a coffee table.

"If people have an attitude about my job," she says, "I just feel sorry for them for not understanding that there's a difference between me and a prostitute."

Greene's career choice is getting newfound attention from "The Sessions," a movie based on the true story of Mark O'Brien, a journalist and poet paralyzed from the neck down. Greene, played in the film by Helen Hunt, was hired by the late O'Brien when he wanted to lose his virginity at age 38.

Not all of the attention is positive. Although some in the country's small community of sex surrogates are hopeful that "The Sessions" might inspire more people to join the profession, others say the movie does not accurately depict the career path and its therapeutic worth.

"I would never get naked in my first session with someone like Cheryl's character does in the movie," says Shai Rotem, a 43-year-old male surrogate, who began his career in his native Israel and now practices in Los Angeles. "We have to get to know one another first and develop a safe rapport."

Greene is one of fewer than 40 practicing partner therapists in the U.S. certified by the International Professional Surrogates Assn., a governing body for the industry.

Two decades ago, there were hundreds of surrogates working in the U.S. after sex researchers William Masters and Virginia Johnson popularized the idea in their 1970 book "Human Sexual Inadequacy." With the rise of AIDS in the mid-1980s, many spouses of surrogates insisted their partners quit the profession.

"There's no law against it because the intent is not to exchange sex for money," says IPSA president Vena Blanchard. "These clients are paying tons of money to sit and talk and do breathing exercises and learn about their body. So much of the work has nothing to do with intercourse or arousal."

Greene, who speaks with a thick Boston accent, was born in Salem, Mass., grew up Catholic and converted to Judaism after marrying her first husband, Michael Cohen. She and Cohen had an open marriage, which in the 1970s wasn't unusual among their Bay Area peers. She also worked as a nude art model and walked around her home naked, even with her children in the room.

THE ENVELOPE: Coverage of the awards season

She first considered becoming a surrogate after a friend handed her a copy of the pseudonymous "Surrogate Wife: The Story of a Masters & Johnson Sexual Therapist and the Nine Cases She Treated." The friend told her, "I think you would be good at this work."

She learned to practice conjoint therapy — where two or more people work through issues together — from two therapists who trained with Masters and Johnson.
