China Toughens Restrictions on Internet Use

How Hwee Young/European Pressphoto Agency

New measures by the Chinese government could chill some of the vibrant discourse on Twitter-like microblogs.

HONG KONG — The Chinese government issued new rules on Friday requiring Internet users to provide their real names to service providers, while assigning Internet companies greater responsibility for deleting forbidden postings and reporting them to the authorities.

The decision came as government censors have sharply stepped up restrictions on China’s international Internet traffic in recent weeks. The restrictions are making it harder for businesses to protect commercial secrets and for individuals to view overseas Web sites that the Chinese Communist Party deems politically sensitive.

The new regulations, issued by the Standing Committee of the National People’s Congress, allow Internet users to continue to adopt pseudonyms for their online postings, but only if they first provide their real names to service providers, a measure that could chill some of the vibrant discourse on the country’s Twitter-like microblogs. The authorities periodically detain and even jail Internet users for politically sensitive comments, such as calls for a multiparty democracy or accusations of impropriety by local officials.

Any entity providing Internet access, including over fixed-line or mobile phones, “should when signing agreements with users or confirming provision of services, demand that users provide true information about their identities,” the committee ordered.

In recent weeks, Internet users in China have exposed a series of sexual and financial scandals that have led to the resignations or dismissals of at least 10 local officials. International news media have also published a series of reports in recent months on the accumulation of wealth by the family members of China’s leaders, and some Web sites carrying such reports, including Bloomberg’s and the English- and Chinese-language sites of The New York Times, have been assiduously blocked, while Internet comments about them have been swiftly deleted.

The regulations issued Friday build on a series of similar administrative guidelines and municipal rules issued over the past year. China’s mostly private Internet service providers have been slow to comply with them, fearing the reactions of their customers. The committee’s decision has much greater legal force, and puts far more pressure on Chinese Internet providers to comply more quickly and more comprehensively, Internet specialists said.

In what appeared to be an effort to make the decision more palatable to the Chinese public, the committee also included a mandate for businesses in China to be more cautious in gathering and protecting electronic data.

“Nowadays on the Internet there are very serious problems with citizens’ personal electronic information being recklessly collected, used without approval, illegally disclosed, and even traded and sold,” Li Fei, a deputy director of the committee’s legislative affairs panel, said on Friday at a news conference in Beijing. “There are also a large number of cases of invasive attacks on information systems to steal personal electronic information, as well as lawbreaking on the Internet through swindles and through defaming and slandering others.”

Mr. Li denied that the government was seeking to prevent the exposure of corruption.

“When citizens exercise these rights according to the law, no organization or individual can use any reason or excuse to interfere, and cannot suppress them or exact revenge,” he said. “At the same time, when citizens exercise their rights, including through use of the Internet, they should stay within the bounds of the Constitution and the laws, and must not harm the legitimate rights and interests of the state, society, the collective or of other citizens.”

A spokesman for the National People’s Congress said that 145 members of the committee voted in favor of the new rules, with 5 abstaining and 1 voting against them.

The requirement for real names appeared to be aimed particularly at cellphone companies and other providers of mobile Internet access. At the news conference, an official from the Ministry of Industry and Information Technology, Zhao Zhiguo, said that nearly all fixed-line services now had real-name registration, but that only about 70 percent of mobile phones were registered under real names.

Media may argue against redactions in church files, judge rules

Media organizations will be allowed to argue against redactions in secret church files that are due to be made public as part of a historic $660-million settlement between the Los Angeles Archdiocese and alleged victims of sexual abuse by priests, a Los Angeles County Superior Court judge ruled Thursday.

Pursuant to Judge Emilie Elias' order, The Times and the Associated Press will be allowed to intervene in the case, in which attorneys are gearing up for the release of internal church personnel documents more than five years after the July 2007 settlement. The judge's ruling came after attorneys for the church and the plaintiffs agreed to the news organizations' involvement in the case.

The Times and the AP object to a portion of a 2011 decision by a retired judge overseeing the file-release process. Judge Dickran Tevrizian had ruled that all names of church employees, including Cardinal Roger M. Mahony and other top archdiocese officials, should be blacked out in the documents before they were made public. In a hearing, Tevrizian said he did not believe the documents should be used to "embarrass or to ridicule the church."

Attorneys for the news organizations argued in court filings that the redactions would "deny the public information that is necessary to fully understand the church's knowledge about the serial molestation of children by priests over a period of decades." The personnel files of priests accused of molestation, which a church attorney has said were five or six banker's boxes of documents, could include internal memos about abuse claims, Vatican correspondence and psychiatric reports.

Contending that the secrecy was motivated by "a desire to avoid further embarrassment" for the church rather than privacy concerns, the media attorneys wrote: "That kind of self-interest is not even remotely the kind of 'overriding interest' that is needed to overcome the public's presumptive right of access, nor does it establish 'good cause' for ongoing secrecy."

An archdiocese attorney said Thursday that the church had spent a "great deal of effort" in redacting the files to comply with Tevrizian's order, and said the media attorneys misunderstand the legal process that both parties in the settlement agreed would be binding.

"We agree with Judge Tevrizian that enough time has passed and enough reforms have been made that it's time to get off this and move onto another subject," attorney J. Michael Hennigan said.

An attorney representing the victims also filed papers Thursday arguing that the church was "too broadly construing" Tevrizian's redaction orders, and asking Elias to release the files with church officials' names unredacted.

"Each of the higher-ups in the Los Angeles Archdiocese who recklessly endangered generations of this community's children by protecting pedophile priests will themselves be protected," wrote Ray Boucher, lead attorney for the plaintiffs.

A hearing on the release of church documents is scheduled for Jan. 7. At the hearing, Elias will also hear objections from an attorney representing individual priests, who contend that their constitutional privacy rights will be violated if the files are made public. In a court filing this month, the priests' attorney, Donald Steier, said Tevrizian was "dead wrong" to rule that the documents can be disclosed because the public interest outweighs the clerics' rights.

"Under California law, it is the employees who own the information in the files, and the Archdiocese is merely the custodian who has a legal duty to defend the contents of the files and has no legal right to agree to disclose them," Steier wrote.

Surgery Returns to NYU Langone Medical Center

Chang W. Lee/The New York Times

Senator Charles E. Schumer spoke at a news conference Thursday about the reopening of NYU Langone Medical Center.

NYU Langone Medical Center opened its doors to surgical patients on Thursday, almost two months after Hurricane Sandy overflowed the banks of the East River and forced the evacuation of hundreds of patients.

While the medical center had been treating many outpatients, it had farmed out surgery to other hospitals, which created scheduling problems that forced many patients to have their operations on nights and weekends, when staffing is traditionally low. Some patients and doctors had to postpone not just elective but also necessary operations for lack of space at other hospitals.

The medical center’s Tisch Hospital, its major hospital for inpatient services, between 30th and 34th Streets on First Avenue, had been closed since the hurricane knocked out power and forced the evacuation of more than 300 patients, some on sleds brought down darkened flights of stairs.

“I think it’s a little bit of a miracle on 34th Street that this happened so quickly,” Senator Charles E. Schumer of New York said Thursday.

Mr. Schumer credited the medical center’s leadership and esprit de corps, and also a tour of the damaged hospital on Nov. 9 by the administrator of the Federal Emergency Management Agency, W. Craig Fugate, whom he and others escorted through watery basement hallways.

“Every time I talk to Fugate there are a lot of questions, but one is, ‘How are you doing at NYU?’ ” the senator said.

The reopening of Tisch to surgery patients and associated services, like intensive care, some types of radiology and recovery room anesthesia, was part of a phased restoration that will continue. Besides providing an essential service, surgery is among the more lucrative of hospital services.

The hospital’s emergency department is expected to delay its reopening for about 11 months, in part to accommodate an expansion in capacity to 65,000 patient visits a year, from 43,000, said Dr. Andrew W. Brotman, its senior vice president and vice dean for clinical affairs and strategy.

In the meantime, NYU Langone is setting up an urgent care center with 31 bays and an observation unit, which will be able to treat some emergency patients. It will initially not accept ambulances, but might be able to later, Dr. Brotman said. Nearby Bellevue Hospital Center, which was also evacuated, opened its emergency department to noncritical injuries on Monday.

Labor and delivery, the cancer floor, epilepsy treatment and pediatrics and neurology beyond surgery are expected to open in mid-January, Langone officials said. While some radiology equipment, which was in the basement, has been restored, other equipment — including a Gamma Knife, a device using radiation to treat brain tumors — is not back.

The flooded basement is still being worked on, and electrical gear has temporarily been moved upstairs. Mr. Schumer, a Democrat, said that a $60 billion bill to pay for hurricane losses and recovery in New York and New Jersey was nearing a vote, and that he was optimistic it would pass in the Senate with bipartisan support. But the measure’s fate in the Republican-controlled House is far less certain.

The bill includes $1.2 billion for damage and lost revenue at NYU Langone, including some money from the National Institutes of Health to restore research projects. It would also cover Long Beach Medical Center in Nassau County, Bellevue, Coney Island Hospital and the Veterans Affairs hospital in Manhattan.

Unemployment Deepens the Loss from Hurricane Sandy

In the Rockaways, none of the 450 employees of the Madelaine Chocolate Company will receive a paycheck this week. Until a few days ago, the floor of the company’s 200,000-square-foot complex was a muddy, sludgy, chocolaty mess, and its factory has temporarily closed. Outside, foiled Santas and candy roses lay victim to the hurricane.

Not far away, the cash register at Fast Break, a local deli, is silent, its employees out of work. Next door, Browns Hardware will be shut until at least February.

The story is much the same throughout the region, where residents who lost their jobs as a result of Hurricane Sandy are streaming into career centers in New York and New Jersey, desperate for a paycheck.

“Here, it’s like anyone who didn’t lose his home lost his job,” said Juan Colon, 57, who worked at Madelaine for 26 years.

The devastating storm, which destroyed many businesses, left tens of thousands of New York and New Jersey residents unemployed. How long they will remain jobless is uncertain. In some cases, they may be able to resume their old jobs as their employers get back on their feet, assuming those businesses reopen.

The latest jobs reports from New York and New Jersey, for November, suggested the toll the storm took on the local labor force — New York State lost 29,100 private jobs, while New Jersey lost 8,100.

In the same month, New Jersey processed an unprecedented number of first-time claims for unemployment insurance: 138,661, surpassing the previous record of 83,518 established in December 2009, which came at the height of the recession. And in New York, 158,204 individuals filed initial claims for unemployment, nearing the record set in January 2009, also at the height of the recession.

The unemployment problem has eased a bit as “Grand Reopening” signs have popped up at mattress stores, gas stations and other businesses. And the number of people filing for unemployment for the first time has slowed significantly in recent weeks.

But there are still many people struggling to pay their bills, finding themselves out of a job at a time when the overall unemployment picture remains bleak.

“We were spared the storm, but not the repercussions,” said Hector Valle, 57, who lives on Staten Island. The hurricane left Mr. Valle’s home untouched, but dealt his family a mighty blow: His wife worked at Bellevue Hospital Center as a nurse’s assistant for the last 25 years. When the hurricane shuttered Bellevue, she was transferred to Woodhull Medical Center — a move that caused her to lose her overtime work, as well as part of her night differential pay.

The couple’s income fell to $1,400 a month from $2,200 a month.

“There’s nobody coming to my house to help,” said Mr. Valle, who has been unemployed for three years, “because they’re like, ‘You’re fine.’ We’re not fine.”

Those most affected are the people who already have trouble finding jobs: older workers, single parents with child-care concerns and immigrants who speak little English.

And the storm has further handicapped many of those looking for new work: Interview outfits lie moldy in Dumpsters; computers have been destroyed, résumé files gone forever. Many lack access to transportation. “There are a lot of barriers to employment, from no phone to no home,” said Thomas Munday, director of a city-run Workforce 1 Career Center on Staten Island.

When they do get jobs, many residents will face new, longer commutes, and fewer benefits.

At the Madelaine chocolate company this month, Jorge Farber, the president and chief executive, shuffled past ribbons of ruined Reese’s foil, wearing yellow rubber shoe covers slicked with slime. He intends to reopen, but could not estimate a date.

The company is the largest employer in the Rockaways, and normally pumps out 100,000 pounds of chocolate a day. It was started 64 years ago by two men fleeing the Holocaust, and about a quarter of its employees are Haitian immigrants. Many had family members who died in the 2010 Haitian earthquake.

Some of the laid-off employees have packaged chocolate here for decades. For them, Mr. Farber said, the company is a good provider: Line workers, many of whom do not speak English, make about $15 an hour, plus benefits. It would be difficult for them to find new jobs with the same salary and benefits.

Over nearly three decades, Mr. Colon rose to a supervisor position, earning about $900 a week.

When the storm left him without a job, he signed up for unemployment benefits. But he is getting only $325 a week, he said.

“I don’t know what I will do,” said Mr. Colon, who lives in a fourth-floor apartment in Far Rockaway with his wife, 22-year-old daughter and a grandchild. “Nobody can survive on $300.”

There is no telling when the company will be able to bring him back.

Some may find work related to hurricane recovery. New York State qualified for a federal grant that will allow it to hire 5,000 temporary cleanup workers for jobs that last about six months and pay $11 to $15 an hour. The city has already hired 788 people to fill some of those temporary jobs, according to Angie Kamath, deputy commissioner of work force development for the city’s Department of Small Business Services. And it will hire 400 more in the coming weeks, she said.

“We hope and expect that that number will continue to grow,” Ms. Kamath said. “The state has every intention to go after additional funding.”

The storm’s aftermath has also created private jobs. Areas hit by hurricanes almost always see a temporary boost in employment because of rebuilding activities, said Allison Plyer, chief demographer at the Greater New Orleans Community Data Center, which tracked employment after Hurricane Katrina. “There will be no doubt billions of dollars of private and flood insurance to rebuild homes and businesses,” she said.

But few of those jobs will last. Many will go to out-of-state contractors. And not everyone who is out of work can fill labor-intensive cleanup positions.

Ms. Plyer also cautioned against using the experience of Hurricane Katrina to predict what will happen after Hurricane Sandy.

After Hurricane Katrina, residential areas were destroyed, while New Orleans’s business district remained relatively intact. Businesses bounced back, but the housing stock and the area’s population did not, leaving employers seeking workers. “Unemployment rates sunk to their lowest level,” Ms. Plyer said, continuing: “All the McDonald’s were offering signing bonuses. You couldn’t find anyone to work for them.”

“Katrina entailed a massive population displacement that basically emptied out the city,” she added.

On Staten Island, unemployed residents inundated a city-operated career center in St. George after the storm. About 500 people showed up during two days to apply for 240 storm cleanup jobs. (Normally 350 individuals will seek employment assistance during a five-day week.)

Mr. Valle, who once worked as a customer service representative, waited outside the center hoping to land one of those cleanup jobs. He left when all the positions had been filled.

“That was like an audition for ‘American Idol,’ ” he said. “I have never been in line with 500, 600 people for a job in my life.”

His wife, he said, had been their support for the last three years. “Sandy just yanked that from under us,” he said.

Toyota to pay big to settle suits

Toyota Motor Corp., moving to put years of legal problems behind it, has agreed to pay more than $1 billion to settle dozens of lawsuits relating to sudden acceleration.

The proposed deal, filed Wednesday in federal court, would be among the largest ever paid out by an automaker. It applies to numerous suits claiming economic damages caused by safety defects in the automaker's vehicles, but does not cover dozens of personal injury and wrongful-death suits that are still pending around the nation.

The suits were filed over the last three years by Toyota and Lexus owners who claimed that the value of their vehicles had been hurt by the potential for defects, including floor mats that could cause the vehicles to surge out of control.

ROAD TO RECALL: Read The Times' award winning coverage

In addition, Toyota said it is close to settling suits filed by the Orange County district attorney and a coalition of state attorneys general who had accused the automaker of deceptive business practices. The costs of those agreements would be included in a $1.1-billion charge the Japanese automaker said it will take against earnings to cover the actions.

"We concluded that turning the page on this legacy legal issue through the positive steps we are taking is in the best interests of the company, our employees, our dealers and, most of all, our customers," Christopher Reynolds, Toyota's chief counsel in the U.S., said in a statement.

Toyota's lengthy history of sudden acceleration was the subject of a series of Los Angeles Times articles in 2009, after a horrific crash outside San Diego that took the life of an off-duty California Highway Patrol officer and his family.

Under terms of the agreement, which has not yet been approved in court, Toyota would install brake override systems in numerous models and provide cash payments from a $250-million fund to owners whose vehicles cannot be modified to incorporate that safety measure.

In addition, the automaker plans to offer extended repair coverage on throttle systems in 16 million vehicles and offer cash payments from a separate $250-million fund to Toyota and Lexus owners who sold their vehicles or turned them in at the end of a lease in 2009 or 2010. The total value of the settlement could reach $1.4 billion, according to Steve Berman, the lead plaintiff attorney in the case.

The lawsuits, filed over the last several years, had been seeking class certification.

News of the agreement comes scarcely a week after Toyota agreed to pay a record $17.35-million fine to the National Highway Traffic Safety Administration for failing to report a potential floor mat defect in a Lexus SUV. Those come on top of almost $50 million in fines paid by Toyota for other violations related to sudden acceleration since 2010.

The massive settlement does not, however, put Toyota's legal woes to rest. The automaker still faces numerous injury and wrongful death claims around the country, including a group of cases that have been consolidated in federal court in Santa Ana, and other cases awaiting trial in Los Angeles County.

The first of the federal cases, involving a Utah man who was killed in a Camry that slammed into a wall in 2010, is slated for trial in mid-February.

The California cases are set to begin in April, among them a suit involving a 66-year-old Upland woman who was killed after her vehicle allegedly reached 100 miles per hour and slammed into a tree.

Edgar Heiskell III, a West Virginia attorney who has a dozen pending suits against Toyota, said he is preparing to go to trial this summer in a case that involved a Flint, Mich., woman who was killed when her 2005 Camry suddenly accelerated near her home.

"We are proceeding with absolute confidence that we can get our cases heard on the merits and that we expect to prove defects in Toyota's electronic control system," he said.

Toyota spokesman Mike Michels said the settlement would have no bearing on the personal injury cases.

"All carmakers face these kinds of suits," he said. "We'll defend those as we normally would."

The giant automaker's sudden acceleration problems first gained widespread attention after the August 2009 crash of a Lexus ES outside San Diego.

That accident set off a string of recalls, an unprecedented decision to temporarily stop sales of all Toyota vehicles and a string of investigations, including a highly unusual apology by Toyota President Akio Toyoda before a congressional committee. Eventually Toyota recalled more than 10 million vehicles worldwide and has since spent huge sums — estimated at more than $2 billion, not including Wednesday's proposed settlement — to repair both its automobiles and public image.

Google Music Self-Censoring Naughty Lyrics for Some Users

Cee-Lo’s F*#$ You has a great beat and all, but it’s not the type of thing you want queuing up with grandma in the room. No worries. Google’s got you covered. Some Google Music users complain the service is randomly replacing expletive-intensive songs with the duller, cleaner versions.

The Google Music Scan and Match feature has earned the wrath of some users by replacing explicit versions of songs with the kid-friendly clean versions. Even less fun, Droid Life reports that some people are seeing clean versions of songs replaced with explicit versions. That’s bad news when you expect to hear the sanitized version of Radiohead’s Creep while hanging out with your kids. Now you have to spend the rest of winter vacation explaining to them why they can’t sing how so f’ing special they are on the playground.

Google Music isn’t the first service to experience trouble determining which version of a song is being matched. Apple’s iTunes Match experienced the same issue when it launched. The problem stems from a few issues. First, the metadata for a particular song might not be correct, or it might be missing vital information. Like which version of the album the song was ripped or purchased from.

Also, it’s tougher for Google Music and other song-matching services to determine if a song is clean or explicit if a curse word only appears once or twice during the song. Cee-Lo’s F*#$ You is easier to rate because the change takes place throughout the entire song.

If you find that your favorite 2 Live Crew songs are completely unlistenable, Google told Wired that listeners could change the version of the song from within the Google Music player. In the Google Music Player, right-click the track with the incorrect version. Select “Fix incorrect match” from the contextual menu. The actual song file will be uploaded to the service instead of using Google’s matching system.

Not exactly user friendly, but better than listening to beeps over your favorite swear words. Everyone knows all the best music is full of swear words.

DC police investigating ‘Meet the Press’ incident

WASHINGTON (AP) — District of Columbia police say they are investigating an incident in which NBC News journalist David Gregory displayed what he described as a high-capacity ammunition magazine on “Meet the Press.”

Gun laws in the nation’s capital generally restrict the possession of high-capacity magazines, regardless of whether the device is attached to a firearm. Gregory held up the magazine as a prop for Sunday’s segment, apparently to make a point during an interview, even though D.C. police say NBC had already been advised not to use it in the show.

“NBC contacted (the Metropolitan Police Department) inquiring if they could utilize a high capacity magazine for their segment. NBC was informed that possession of a high capacity magazine is not permissible and their request was denied. This matter is currently being investigated,” police spokeswoman Gwendolyn Crump said in a written statement. She declined to comment further.

While interviewing National Rifle Association CEO Wayne LaPierre for Sunday’s program, Gregory held up an object that he said was a magazine that could hold 30 rounds.

“Here is a magazine for ammunition that carries 30 bullets. Now, isn’t it possible that if we got rid of these, if we replaced them and said, ‘Well, you can only have a magazine that carries five bullets or ten bullets,’ isn’t it just possible that we could reduce the carnage in a situation like Newtown?’” Gregory asked, referring to the December 14 shooting in which a gunman massacred 20 children and 6 adults at Sandy Hook Elementary School in Connecticut.

LaPierre replied: “I don’t believe that’s going to make one difference. There are so many different ways to evade that even if you had that” ban.

It was not clear how or where Gregory obtained the magazine, and an NBC News spokeswoman declined to comment Wednesday.

“Meet the Press” is generally taped in Washington.

Elwood V. Jensen, Pioneer in Breast Cancer Treatment, Dies at 92

Elwood V. Jensen, a medical researcher whose studies of steroid hormones led to new treatments for breast cancer that have been credited with saving or extending hundreds of thousands of lives, died on Dec. 16 in Cincinnati. He was 92.

The cause was complications of pneumonia, his son, Thomas Jensen, said.

In 2004 Dr. Jensen received the Albert Lasker Basic Medical Research Award, one of the most respected science prizes in the world.

When Dr. Jensen started his research at the University of Chicago in the 1950s, steroid hormones, which alter the functioning of cells, were thought to interact with cells through a series of chemical reactions involving enzymes.

However, Dr. Jensen used radioactive tracers to show that steroid hormones actually affect cells by binding to a specific receptor protein inside them. He first focused on the steroid hormone estrogen.

By 1968, Dr. Jensen had developed a test for the presence of estrogen receptors in breast cancer cells. He later concluded that such receptors were present in about a third of those cells.

Breast cancers that are estrogen positive, meaning they have receptors for the hormone, can be treated with medications like Tamoxifen or with other methods of inhibiting estrogen in a patient’s system, like removal of the ovaries. Women with receptor-rich breast cancers often go into remission when estrogen is blocked or removed.

By the mid-1980s, a test developed by Dr. Jensen and a colleague at the University of Chicago, Dr. Geoffrey Greene, could be used to determine the extent of estrogen receptors in breast and other cancers. That test became a standard part of care for breast cancer patients.

Scientists like Dr. Pierre Chambon and Dr. Ronald M. Evans, who shared the 2004 Lasker prize with Dr. Jensen, went on to show that many types of receptors exist. The receptors are crucial components of the cell’s control system and transmit signals in an array of vital functions, from the development of organs in the womb to the control of fat cells and the regulation of cholesterol.

Dr. Jensen’s work also led to the development of drugs that can enhance or inhibit the effects of hormones. Such drugs are used to treat prostate and other cancers.

Elwood Vernon Jensen was born in Fargo, N.D., on Jan. 13, 1920, to Eli and Vera Morris Jensen. He majored in chemistry at what was then Wittenberg College in Springfield, Ohio, and had begun graduate training in organic chemistry at the University of Chicago when World War II began.

Dr. Jensen wanted to join the Army Air Forces, but his poor vision kept him from becoming a pilot. During the war he synthesized poison gases at the University of Chicago, exposure to which twice put him in the hospital. His work on toxic chemicals, he said, inspired him to pursue biology and medicine.

Dr. Jensen studied steroid hormone chemistry at the Swiss Federal Institute of Technology on a Guggenheim Fellowship after the war. While there, he climbed the Matterhorn, one of the highest peaks in the Alps, even though he had no mountaineering experience. He often equated his successful research to the novel approach taken by Edward Whymper, the first mountaineer to reach the Matterhorn’s summit. Mr. Whymper went against conventional wisdom and scaled the mountain’s Swiss face, after twice failing to reach the summit on the Italian side.

Dr. Jensen joined the University of Chicago as an assistant professor of surgery in 1947, working closely with the Nobel laureate Charles Huggins. He became an original member of the research team at the Ben May Laboratory for Cancer Research (now the Ben May Department for Cancer Research) in 1951, and became the director after Dr. Huggins stepped down.

He came to work at the University of Cincinnati in 2002, and continued to do research there until last year.

His first wife, the former Mary Collette, died in 1982. In addition to his son, Dr. Jensen is survived by his second wife, the former Hiltrud Herborg; a daughter, Karen C. Jensen; a sister, Margaret Brennan; two grandchildren; and three great-grandchildren.

Dr. Jensen’s wife was found to have breast cancer in 2005. She had the tumor removed, he said in an interview, but tested positive for the estrogen receptor and was successfully treated with a medication that prevents estrogen synthesis.
