Manti Te'o girlfriend's death apparently a hoax

SOUTH BEND, Ind. (AP) — Not long before Notre Dame played Michigan State last fall, word spread that Fighting Irish linebacker Manti Te'o had lost his grandmother and girlfriend within hours of each other.

Te'o never missed a practice and made a season-high 12 tackles, two pass breakups and a fumble recovery in a 20-3 victory against the Spartans. His inspired play became a stirring story line for the Fighting Irish as they made a run to the national championship game behind their humble, charismatic star.

Te'o's grandmother did indeed die. His girlfriend, Lennay Kekua, never existed.

In a shocking announcement Wednesday night, Notre Dame said Te'o was duped into an online relationship with a woman whose "death" from leukemia was faked by perpetrators of an elaborate hoax. The goal of the scam wasn't clear, though Notre Dame said it used an investigative firm to dig into the details after Te'o disclosed them three weeks ago.

The hoax was disclosed hours after Deadspin.com posted a lengthy story, saying it could find no record that Kekua ever existed. The story suggests a friend of Te'o may have carried out the hoax and that the football player may have been in on it — a stunning claim against a widely admired All-American who led the most famed program in college football back to the championship game for the first time since 1988.

"This is incredibly embarrassing to talk about, but over an extended period of time, I developed an emotional relationship with a woman I met online," Te'o said in a statement. "We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her. "

However, he stopped short of saying he had ever met her in person or correcting reports that said he had, though he did on numerous occasions talk about how special the relationship was to him.

"To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating," he said. "In retrospect, I obviously should have been much more cautious. If anything good comes of this, I hope it is that others will be far more guarded when they engage with people online than I was."

Word of the hoax spread quickly and raised questions about whether the school somehow played a role in pushing the tale.

Notre Dame athletic director Jack Swarbrick said at a news conference that Te'o told coaches on Dec. 26 that he had received a call from Kekua's phone number while at an awards ceremony during the first week of December.

"When he answered it, it was a person whose voice sounded like the same person he had talked to, who told him that she was, in fact, not dead. Manti was very unnerved by that, as you might imagine," Swarbrick said.

Swarbrick said the school hired investigators and their report indicated those behind the hoax were in contact with each other, discussing what they were doing.

The investigators "were able to discover online chatter among the perpetrators that was certainly the ultimate proof of this, the joy they were taking," Swarbrick said. "The casualness among themselves they were talking about what they accomplished."

Swarbrick said for Te'o "the pain was real."

"The grief was real. The affection was real," he said. "That's the nature of this sad, cruel game."

Swarbrick added: "Nothing about what I have learned has shaken my faith in Manti Te'o one iota."

Swarbrick said Notre Dame did not take the matter to the police, saying that the school left it up to Te'o and his family to do so. He added that Notre Dame did not plan to release the findings of its investigation.

"We had no idea of motive, and that was really significant to us. ... Was somebody trying to create an NCAA violation at the core of this? Was there somebody trying to impact the outcome of football games by manipulating the emotions of a key player? Was there an extortion request coming? When you match the lack of sort of detail we lacked until we got some help investigating it with the risk involved, it was clear to me until we knew more we had to just to continue to work to try to gather the facts," Swarbrick said.

The Deadspin report changed all that.

Friends and relatives of Ronaiah Tuiasosopo told Deadspin they believe he created Kekua. The website said Te'o and Tuiasosopo knew each other. Attempts by The Associated Press to reach Tuiasosopo by telephone were unsuccessful.

As for Kekua, Deadspin said she does not have a death certificate. Stanford, where she reportedly went to school, has no record of anybody by that name, the website said. Deadspin said a record search produced no obituary or funeral announcement. There is no record of her birth in the news.

There are a few Twitter and Instagram accounts registered to Lennay Kekua, but the website reported that photographs identified as Kekua online and in TV news reports are pictures from the social-media accounts of a 22-year-old California woman who is not named Lennay Kekua.

Te'o talked freely about their relationship after her supposed death and how much she meant to him.

In a story that appeared in The South Bend Tribune on Oct. 12, Manti's father, Brian, recounted an anecdote about how his son and Kekua met after Notre Dame had played at Stanford in 2009. Brian Te'o also told the newspaper that Kekua had visited Hawaii and met with his son. Brian Te'o told the AP in an interview in October that he and his wife had never met Manti's girlfriend but they had hoped to at the Wake Forest game in November. The father said he believed the relationship was just beginning to get serious when she died.

The Tribune released a statement saying: "At the Tribune, we are as stunned by these revelations as everyone else. Indeed, this season we reported the story of this fake girlfriend and her death as details were given to us by Te'o, members of his family and his coaches at Notre Dame."

The week before Notre Dame played Michigan State on Sept. 15, coach Brian Kelly told reporters when asked that Te'o's grandmother and a friend had died. He said Kekua had told Te'o not to miss a game if she died. The linebacker turned in one of his best performances of the season and his playing through heartache became a prominent theme during the Irish's undefeated regular season. He finished second in Heisman voting.

"It further pains me that the grief I felt and the sympathies expressed to me at the time of my grandmother's death in September were in any way deepened by what I believed to be another significant loss in my life," Te'o said in his statement.

"I am enormously grateful for the support of my family, friends and Notre Dame fans throughout this year. To think that I shared with them my happiness about my relationship and details that I thought to be true about her just makes me sick. I hope that people can understand how trying and confusing this whole experience has been."

Te'o and the Irish lost the title game to Alabama, 42-14 on Jan. 7. He has graduated and was set to begin preparing for the NFL combine and draft at the IMG Academy in Bradenton, Fla., this week.

"Fortunately, I have many wonderful things in my life," he said in his statement, "and I'm looking forward to putting this painful experience behind me as I focus on preparing for the NFL draft."

Some With Autism Diagnosis Can Recover, Study Finds

Doctors have long believed that disabling autistic disorders last a lifetime, but a new study has found that some children who exhibit signature symptoms of the disorder recover completely.

The study, posted online on Wednesday by the Journal of Child Psychology and Psychiatry, is the largest to date of such extraordinary cases and is likely to alter the way that scientists and parents think and talk about autism, experts said.

Researchers on Wednesday cautioned against false hope. The findings suggest that the so-called autism spectrum contains a small but significant group who make big improvements in behavioral therapy for unknown, perhaps biological reasons, but that most children show much smaller gains. Doctors have no way to predict which children will do well.

Researchers have long known that between 1 and 20 percent of children given an autism diagnosis no longer qualify for one a few years or more later. They have suspected that in most cases the diagnosis was mistaken; the rate of autism diagnosis has ballooned over the past two decades, and some research suggests that it has been loosely applied.

The new study should put some of that skepticism to rest.

“This is the first solid science to address this question of possible recovery, and I think it has big implications,” said Sally Ozonoff of the MIND Institute at the University of California, Davis, who was not involved in the research. “I know many of us as would rather have had our tooth pulled than use the word ‘recover,’ it was so unscientific. Now we can use it, though I think we need to stress that it’s rare.”

She and other experts said the findings strongly supported the value of early diagnosis and treatment.

In the study, a team led by Deborah Fein of the University of Connecticut at Storrs recruited 34 people who had been diagnosed before the age of 5 and no longer had any symptoms. They ranged in age from 8 to 21 years old and early in their development were in the higher-than-average range of the autism spectrum. The team conducted extensive testing of its own, including interviews with parents in some cases, to gauge current social and communication skills.

The debate over whether recovery is possible has simmered for decades and peaked in 1987, when the pioneering autism researcher O. Ivar Lovaas reported that 47 percent of children with the diagnosis showed full recovery after undergoing a therapy he had devised. This therapy, a behavioral approach in which increments of learned skills garner small rewards, is the basis for the most effective approach used today; still, many were skeptical and questioned his definition of recovery.

Dr. Fein and her team used standardized, widely used measures and found no differences between the group of 34 formerly diagnosed people and a group of 34 matched control subjects who had never had a diagnosis.

“They no longer qualified for the diagnosis,” said Dr. Fein, whose co-authors include researchers from Queens University in Kingston, Ontario; Children’s Hospital of Philadelphia; the Institute of Living in Hartford; and the Child Mind Institute in New York. “I want to stress to parents that it’s a minority of kids who are able to do this, and no one should think they somehow missed the boat if they don’t get this outcome.”

On measures of social and communication skills, the recovered group scored significantly better than 44 peers who had a diagnosis of high-functioning autism or Asperger’s syndrome.

Dr. Fein emphasized the importance of behavioral therapy. “These people did not just grow out of their autism,” she said. “I have been treating children for 40 years and never seen improvements like this unless therapists and parents put in years of work.”

The team plans further research to learn more about those who are able to recover. No one knows which ingredients or therapies are most effective, if any, or if there are patterns of behavior or biological markers that predict such success.

“Some children who do well become quite independent as adults but have significant anxiety and depression and are sometimes suicidal,” said Dr. Fred Volkmar, the director of the Child Study Center at the Yale University School of Medicine. There are no studies of this group, he said.

That, because of the new study, is about to change.

Regulators Around the Globe Ground Boeing 787s

Kyodo News, via Reuters

The 787 that made an emergency landing in Japan on Wednesday. All 137 passengers and crew members were evacuated safely.

Regulators around the globe ordered the grounding of Boeing 787s on Thursday until they could determine what caused a new type of battery to catch fire on two planes in recent days.

The directives in Europe, India and Japan followed an order Wednesday by the U.S. Federal Aviation Administration grounding the planes operated by U.S. carriers.

The decisions are a result of incidents involving a plane that was parked in Boston and one in Japan that had to make an emergency landing Wednesday morning after an alarm warning of smoke in the cockpit.

In Japan on Thursday, the transportation ministry issued a formal order to ground all 787s indefinitely, until concerns over the aircraft’s battery systems are resolved. All Nippon Airways and Japan Airlines had already voluntarily grounded their 787s on Wednesday.

European safety regulators also said they would ground Dreamliners, affecting LOT of Poland, the only carrier that operates the jets in that region. In India, the aviation regulator grounded all six of the 787s operated by the state-owned carrier Air India.

LAN Airlines of Chile said it was following suit, acting in coordination with the Chilean Aeronautical Authority.

And on Thursday, Qatar Airways said it would follow the F.A.A.’s decision and ground its five 787s, effective immediately.

The F.A.A.’s emergency directive, issued Wednesday night, initially applies to United Airlines, the only American carrier using the new plane so far, with six 787s.

Boeing, based in Chicago, has a lot riding on the 787, and its stock dropped nearly 3.4 percent Wednesday to $74.34. The company has outlined ambitious plans to double its production rate to 10 planes a month by the end of 2013. It is also starting to build a stretch version and considering an even larger one after that.

“We are confident the 787 is safe and we stand behind its overall integrity,” Jim McNerney, Boeing’s chief executive, said in a statement.

The grounding — an unusual action for a new plane — focuses on one of the more risky design choices made by Boeing, namely to make extensive use of lithium-ion batteries aboard its airplanes for the first time.

Until now, much of the attention on the 787 was focused on its lighter composite materials and more efficient engines, meant to usher in a new era of more fuel-efficient travel, particularly over long distances. The batteries are part of an electrical system that replaces many mechanical and hydraulic ones that are common in previous jets.

The 787’s problems could jeopardize one of its major features, its ability to fly long distances at a lower cost. The plane is certified to fly 180 minutes from an airport. The U.S. government is unlikely to extend that to 330 minutes, as Boeing has promised, until all problems with the plane have been resolved.

For Boeing, “it’s crucial to get it right,” said Richard L. Aboulafia, an aviation analyst at Teal Group in Fairfax, Virginia. “They’ve got a brief and closing window in which they can convince the public and their flying customers that this is not a problem child.”

The 787 uses two identical lithium-ion batteries, each about one and a half to two times the size of a typical car battery. One battery, in the rear electrical equipment bay near the wings, is used to start the auxiliary power unit, a small engine in the tail that is used most often to provide power for the plane while it is on the ground. The other battery, called the main battery, starts the pilot’s computer displays and serves as a backup for flight systems.

The maker of the 787’s batteries, GS Yuasa of Japan, has declined to comment on the problems.

Boeing has defended the novel use of the batteries and said it had put in place a series of systems meant to prevent overcharging and overheating.

In a conference call last week with reporters, Boeing’s chief engineer for the 787, Mike Sinnett, said that the company had long been aware of possible problems with lithium-ion batteries but that it had built in numerous redundant features to keep any problems with the batteries from threatening the plane in flight. He said that the batteries had not had any problems in 1.3 million hours of flight and that Boeing was trying to understand what had caused the problems.

India Ink: India's Man Problem

As India grapples with what seems like a constant barrage of shocking acts of violence against women, one question is asked again and again: Why is this happening?

One answer, some experts say, is India’s gender ratio, distorted by the practice of sex selection in favor of baby boys.

A much-cited 2002 study,“A Surplus of Men, a Deficit of Peace,” by Valerie M. Hudson and Andrea den Boer, contends that a gender imbalance in Asian countries, caused by a shortage of marriageable women, results in higher rates of crime, including rape, committed by young unmarried men.

“Internal instability is heightened in nations displaying exaggerated gender inequality, leading to an altered security calculus for the state,” the authors wrote in 2002, and reiterated in a book on the subject. Their conclusions are even more true today, Ms. Hudson said in an e-mail interview.

“Certainly the situation is, if anything, worse in both India and China than it was 10 years ago,” she wrote. “Certainly violent crime against women increases as the deficit of women increases. This will constrain the life chances of females far into the future.”

Right now, the statistics are worrying. India has 37 million more men than women, as of 2011 census data, and about 17 million excess men in the age group that commits most crimes, up from 7 million in 1991.

Violent crime in India rose nearly 19 percent from 2007 to 2011, while the kidnapping of women (much of which is related to forced marriage) increased 74 percent in that time. That’s a marked increase from the five years before 2007, when violent crime actually fell by 2.8 percent, and the kidnapping of women rose by 41 percent.

If the study’s conclusions are correct, India’s problems with rape and other forms of violence against women – recently seen in the gang rape and subsequent death of a 23-year-old woman on a bus in Delhi, the gang rape of a high school student in Bihar state and the rape of a young woman in Punjab, who committed suicide afterward – may only get worse, given the trend in India’s demographics.

The authors adopted a Chinese term, guang gun-er (“bare branches”), for unmarried men from age 15 to their mid-30s who have limited prospects for employment. This group, which is larger in countries where sex selection is prevalent, usually “commits the preponderance of violence within a society,” according to the report.

In a marriage market where women are scarce and thus able to “marry up,” certain characteristics of young surplus males are easily and accurately predicted. They are liable to come from the lowest socioeconomic class, be un- or underemployed, live a fairly nomadic or transient lifestyle with few ties to the communities in which they are working, and generally live and socialize with other bachelors. In sum, these young surplus males may be considered, relatively speaking, losers in societal competition.

Marital status affects more than just social standing for these men, the authors argued. Citing research indicating that levels of testosterone (referred to as “T” in the following quote) decline for married men, they said that marriage can thwart potentially antisocial male behavior.

When T falls, so does the propensity to engage in these behaviors. The more men in the society who are unable to marry, even though they would be willing to marry, the higher their circulating T and the greater amount of antisocial, violent and criminal behavior they will exhibit, generally speaking, than if they were able to marry.

A study on the sexuality of “bare branches” in China this year elaborated on the issues that arise with these carnally charged young men. The report said a “series of problems from sexual repression to sexual conflicts, from sexually transmitted diseases (including AIDS) to sexual crimes can arise.”

Intermingling and aggregation are key to understanding “bare branches,” according to Ms. Hudson and Ms. den Boer’s study. These men hang out together, befriend each other, compete with each other and legitimize each others’ “risky choices.” When clumped together and left to their own devices, they become a tool of social disorder, the authors said:

In this “least common denominator” theory, the behavior of men in groups — most particularly young, single, low-status males — will not rise above the behavior of the worst-behaved individual. Together, they will take larger risks and be more violent than they otherwise would individually.

The sheer number of bare branches, coupled with the distinctive outcast subculture that binds them together and their lack of “stake” in the existing social order, predispose them to organized social banditry. The potential for intrasocietal violence is increased when society selects for bare branches, as certain Asian societies do. It is possible that this intrasocietal violence may have intersocietal consequences as well.

According to the 2011 crime statistics in India, of all the people arrested for rape crimes, almost 60 percent were men between the ages of 18 to 30 years and nearly 30 percent were men between the ages of 30 to 45 years.

India’s total sex ratio — defined as the number of females per 1,000 males — has increased over the past 20 years, after dropping for the 80 years before that. As of 2011, there were 940 Indian women for every 1,000 men, up from 933 in 2001. But, thanks to population growth and a still-prevalent practice of female foeticide, the number of “extra men” is growing among India’s youth. There will be about 30 million extra men in India between the age of 15 and 35, the study estimates.

And among India’s youngest population, the gender ratio is still getting worse, perhaps setting the foundation for new generations of violent crime and attacks on women, experts say.

India’s child population, defined in the national census data as all children between the ages of zero and 6 years, was almost 160 million as of 2011. The overall sex ratio for this age group is 914 female children for every 1,000 male children, and it is even more skewed in the urban parts, at 902. These figures mark a severe decline from a decade ago.

Overall, the Indian average gender ratio is far behind the global average of 984 for every 1,000 men, and is the second lowest in the world, before China. Urban India is on par with China though, with 926 women per 1,000 men.

India’s Planning Commission, in a report on women’s rights and child rights released last year, called the gender imbalance in the sex ratio “a silent demographic disaster in the making.”

The report said that the heavily patriarchal areas in the north and northwest have shown a mild improvement in the gender ratio for children, but that most of India has seen it decline. The number of female children relative to male children is expected to remain very low, according to the report.

The Indian government has tried to mend this deteriorating ratio through cash incentive programs that began in 2007. The idea, officials said, was to “force the families to look upon the girl as an asset rather than a liability since her very existence has led to cash inflow to the family.”

However, a recent evaluation of these various programs shows that they have way too many muddled conditions and imprecise focus groups.

“I think it is true that unless the government is willing to enforce its own laws against dowry and sex-selective abortion, not much will change,”  Professor Hudson said.

Apple scoops PBS on “Downton Abbey” episodes, but PBS is cool with it

NEW YORK (TheWrap.com) – Apple is making the entire third season of “Downton Abbey” available on iTunes before every episode airs on PBS – and that’s just fine with PBS.

Fans who buy a season pass on iTunes beginning January 29 will get to see three episodes before they air on PBS. The Season 3 finale airs February 17.

But PBS CEO Paula Kerger isn’t worried that viewers will watch the show online, then tune out PBS. In fact, she says, Apple isn’t the only place Americans can see “Downton” before they can see it on her network.

“You can also buy the DVD sets. They’re being shipped at the end of January, and the DVD sets and Apple are going up at the same time,” Kerger told TheWrap. “I think that for people who are really passionate and want to have it, it’s a great thing.”

Kerger says she hopes more viewers will discover “Downton” on whatever format they like best – and then watch it on PBS next season.

“At the end of the day, my interest is just in seeing it get to the widest possible audience, and there are people that would pick it up on Apple that may not pick it up anywhere else,” she said.

The first episode of the third season premiered to a record 7.9 million viewers earlier this month. Many of those viewers, no doubt, caught up on the previous seasons online or through DVD viewing.

“Downton” airs in the U.K. in the fall but on PBS in January, which means PBS viewers must shield themselves from spoilers. That has led to some grumbling from American fans.

But Kerger said airing the show in January allows the show to get more attention domestically than it might otherwise receive in the crowded fall season.

Lance Armstrong may not be done confessing

Lance Armstrong may not be done confessing.

His interview with Oprah Winfrey hasn't aired yet, but already some people want to hear more — under oath — before Armstrong is allowed to compete in elite triathlons, a sport he returned to after retiring from cycling in 2011. In addition to stripping him of all seven of his Tour de France titles last year, anti-doping officials banned Armstrong for life from sanctioned events.

"He's got to follow a certain course," David Howman, director general of World Anti-Doping Agency, told the AP. "That is not talking to a talk show host."

Armstrong already has had conversations with U.S. Anti-Doping Agency officials, touching off speculation that the team leader who demanded loyalty from others soon may face some very tough choices himself: whether to cooperate and name those who aided, knew about or helped cover up a sophisticated doping ring that Armstrong ran on his tour-winning U.S. Postal Service squads. Former teammate Frankie Andreu, one of several riders Armstrong cast aside on his ride to the top of the sport, said no one could provide a better blueprint for cleaning up the sport.

"Lance knows everything that happened," Andreu told The Associated Press. "He's the one who knows who did what because he was the ringleader. It's up to him how much he wants to expose."

World Anti-Doping Agency officials said nothing short of "a full confession under oath" would even cause them to reconsider the ban. Although Armstrong admitted to Winfrey on Monday that he used performance-enhancing drugs, Howman said that is "hardly the same as giving evidence to a relevant authority." The International Cycling Union also urged Armstrong to tell his story to an independent commission it has set up to examine claims that the sport's governing body hid suspicious samples, accepted financial donations, and helped Armstrong avoid detection in doping tests.

Winfrey wouldn't detail what Armstrong said during their interview at a downtown Austin hotel. In an appearance on "CBS This Morning," she said she was "mesmerized and riveted by some of his answers." What had been planned as a 90-minute broadcast will be shown as a two-part special, Thursday and Friday, on Winfrey's OWN network.

The lifetime ban was imposed after a 1,000-page report by USADA last year outlined a complex, long-running doping program led by Armstrong. The cyclist also lost nearly all of his endorsements and was forced to cut ties with the Livestrong cancer charity he founded in 1997. The damage to Armstrong's reputation was just as severe.

The report portrayed him as well-versed in the use of a wide range of performance-enhancers, including steroids and blood boosters such as EPO, and willing to exploit them to dominate. Nearly a dozen teammates provided testimony about that drug regimen, among them Andreu and his wife, Betsy.

"A lot of it was news and shocking to me," Andreu said. "I am sure it's shocking to the world. There's been signs leading up to this moment for a long time. For my wife and I, we've been attacked and ripped apart by Lance and all of his people, and all his supporters repeatedly for a long time. I just wish they wouldn't have been so blind and opened up their eyes earlier to all the signs that indicated there was deception there, so that we wouldn't have had to suffer as much.

"And it's not only us," he added, "he's ruined a lot of people's lives."

Armstrong was believed to have left for Hawaii. The street outside his Spanish-style villa on Austin's west side was quiet the day after international TV crews gathered there hoping to catch a glimpse of him. Meanwhile, members of his legal team mapped out a strategy on how to handle at least two pending lawsuits against Armstrong, and possibly a third.

Former teammate Floyd Landis, who was stripped of the 2006 Tour de France title for doping, alleges in one of the lawsuits that Armstrong defrauded the U.S. government by repeatedly denying he used performance-enhancing drugs. The False Claims Act lawsuit could require Armstrong to return substantial sponsorship fees and pay a hefty fine. The AP reported earlier Tuesday that Justice Department officials were likely to join the whistleblower lawsuit before a Thursday deadline.

Well: Boosting Your Flu Shot Response

Phys Ed

Gretchen Reynolds on the science of fitness.

As this year’s influenza season continues to take its toll, those procrastinators now hurrying to get a flu shot might wish to know that exercise may amplify the flu vaccine’s effect. And for maximal potency, the exercise should be undertaken at the right time and involve the right dosage of sweat, according to several recent reports.

Flu shots are one of the best ways to lessen the risk of catching the disease. But they are not foolproof. By most estimates, the yearly flu vaccine blocks infection 50 to 70 percent of the time, meaning that some of those being inoculated gain little protection. The more antibodies someone develops, the better their protection against the flu, generally speaking. But for some reason, some people’s immune systems produce fewer antibodies to the influenza virus than others’ do.

Being physically fit has been found in many studies to improve immunity in general and vaccine response in particular. In one notable 2009 experiment, sedentary, elderly adults, a group whose immune systems typically respond weakly to the flu vaccine, began programs of either brisk walking or a balance and stretching routine. After 10 months, the walkers had significantly improved their aerobic fitness and, after receiving flu shots, displayed higher average influenza antibody counts 20 weeks after a flu vaccine than the group who had stretched.

But that experiment involved almost a year of dedicated exercise training, a prospect that is daunting to some people and, in practical terms, not helpful for those who have entered this flu season unfit.

So scientists have begun to wonder whether a single, well-calibrated bout of exercise might similarly strengthen the vaccine’s potency.

To find out, researchers at Iowa State University in Ames recently had young, healthy volunteers, most of them college students, head out for a moderately paced 90-minute jog or bike ride 15 minutes after receiving their flu shot. Other volunteers sat quietly for 90 minutes after their shot. Then the researchers checked for blood levels of influenza antibodies a month later.

Those volunteers who had exercised after being inoculated, it turned out, exhibited “nearly double the antibody response” of the sedentary group, said Marian Kohut, a professor of kinesiology at Iowa State who oversaw the study, which is being prepared for publication. They also had higher blood levels of certain immune system cells that help the body fight off infection.

To test how much exercise really is required, Dr. Kohut and Justus Hallam, a graduate student in her lab, subsequently repeated the study with lab mice. Some of the mice exercised for 90 minutes on a running wheel, while others ran for either half as much time (45 minutes) or twice as much (3 hours) after receiving a flu shot.

Four weeks later, those animals that, like the students, had exercised moderately for 90 minutes displayed the most robust antibody response. The animals that had run for three hours had fewer antibodies; presumably, exercising for too long can dampen the immune response. Interestingly, those that had run for 45 minutes also had a less robust response. “The 90-minute time point appears to be optimal,” Dr. Kohut says.

Unless, that is, you work out before you are inoculated, another set of studies intimates, and use a dumbbell. In those studies, undertaken at the University of Birmingham in England, healthy, adult volunteers lifted weights for 20 minutes several hours before they were scheduled to receive a flu shot, focusing on the arm that would be injected. Specifically, they completed multiple sets of biceps curls and side arm raises, employing a weight that was 85 percent of the maximum they could lift once. Another group did not exercise before their shot.

After four weeks, the researchers checked for influenza antibodies. They found that those who had exercised before the shot generally displayed higher antibody levels, although the effect was muted among the men, who, as a group, had responded to that year’s flu vaccine more robustly than the women had.

Over all, “we think that exercise can help vaccine response by activating parts of the immune system,” said Kate Edwards, now a lecturer at the University of Sydney, and co-author of the weight-training study.

With the biceps curls, she continued, the exercises probably induced inflammation in the arm muscles, which may have primed the immune response there.

As for 90 minutes of jogging or cycling after the shot, it probably sped blood circulation and pumped the vaccine away from the injection site and to other parts of the body, Dr. Kohut said. The exercise probably also goosed the body’s overall immune system, she said, which, in turn, helped exaggerate the vaccine’s effect.

But, she cautions, data about exercise and flu vaccines is incomplete. It is not clear, for instance, whether there is any advantage to exercising before the shot instead of afterward, or vice versa; or whether doing both might provoke the greatest response – or, alternatively, be too much and weaken response.

So for now, she says, the best course of action is to get a flu shot, since any degree of protection is better than none, and, if you can, also schedule a visit to the gym that same day. If nothing else, spending 90 minutes on a stationary bike will make any small twinges in your arm from the shot itself seem pretty insignificant.

Rights Group Reports on Abuses of Surveillance and Censorship Technology

A Canadian human rights monitoring group has documented the use of American-made Internet surveillance and censorship technology by more than a dozen governments, some with harsh human rights policies like Syria, China and Saudi Arabia.

Morgan Marquis-Boire led the research with Mr. Dalek.

The Citizen Lab Internet research group, based at the Munk School of Global Affairs at the University of Toronto, used computer servers to scan for the distinctive signature of gear made by Blue Coat Systems of Sunnyvale, Calif.

It determined that Egypt, Kuwait, Qatar, Saudi Arabia and the United Arab Republic employed a Blue Coat system that could be used for digital censorship. The group also determined that Bahrain, China, India, Indonesia, Iraq, Kenya, Kuwait, Lebanon, Malaysia, Nigeria, Qatar, Russia, Saudi Arabia, South Korea, Singapore, Thailand, Turkey and Venezuela used equipment that could be used for surveillance and tracking.

The authors said they wanted to alert the public that there was a growing amount of surveillance and content-filtering technology distributed throughout the Internet. The technology is not restricted from export by the State Department, except to countries that are on embargo lists, like Syria, Iran and North Korea.

“Our findings support the need for national and international scrutiny of the country Blue Coat implementations we have identified, and a closer look at the global proliferation of dual-use information and communications technology,” the group noted. “We hope Blue Coat will take this as an opportunity to explain their due diligence process to ensure that their devices are not used in ways that violate human rights.”

A spokesman for Blue Coat Systems said the firm had not seen the final report and was not prepared to comment.

In 2011, several groups, including Telecomix and Citizen Labs, raised concerns that Blue Coat products were being used to find and track opponents of the Syrian government. The company initially denied that its equipment had been sold to Syria, which is subject to United States trade sanctions.

Shortly afterward, Blue Coat reversed itself and acknowledged that the systems were indeed in Syria, but it said that the devices had been shipped to a distributor in Dubai, and said that it thought that they had been destined for the Iraqi Ministry of Communications.

The Citizen Lab research project was led by Morgan Marquis-Boire and Jakub Dalek. Mr. Marquis-Boire, a Google software engineer, has during the last year been involved in a variety of research projects aimed at exposing surveillance tools used by authoritarian regimes. He said that he carefully segregated his work at Google from his human rights research.

Last year, Mr. Marquis-Boire used computer servers to identify the use of an intelligence-oriented surveillance software program, called FinSpy, which was being used by Bahrain to track opposition activists.

On a hunch last month, the researchers used the Shodan search engine, a specialized Internet tool intended to help identify computers and software services that were connected to the Internet. They were able to identify a number of the Blue Coat systems that are used for content filtering and for “deep packet inspection,” a widely used technology for detecting and controlling digital content as it travels through the Internet.

The researchers stressed that they were aware that there were both benign and harmful uses for the Blue Coat products identified as ProxySG, which functions as a Web filter, and a second system, PacketShaper, which can detect about 600 Web applications and can be used to control undesirable Web traffic.

“I’m not trying to completely demonize this technology,” Mr. Marquis-Boire said.

The researchers also noted that the equipment does not directly fall under the dual-use distinction employed by the United States government to control the sale of equipment that has both military and civilian applications, but it can be used for both political and intelligence applications by authoritarian governments.

“Syria is subject to U.S. export sanctions,” said Sarah McKune, a senior researcher at the Citizen Lab. “When it comes to other countries that aren’t subject to U.S. sanctions it’s a more difficult situation. There could still be significant human rights impact.”

The researchers also noted that a large number of American and foreign companies supplied similar gear in what Gartner, the market research firm, described as a $1.02 billion market in a report issued in May 2012.

The researchers said that some American security technology companies, like Websense, had taken strong human rights stands, but had declined to grapple with the issue of the possible misuse of the technology.

Pakistan High Court Orders Arrest of Prime Minister

Supporters of Muhammad Tahir ul Qadri, who addressed protesters outside parliament on Tuesday, repeated calls for the ouster of the government.

ISLAMABAD, Pakistan – Pakistan’s supreme court ordered the arrest of Prime Minister Raja Pervez Ashraf in a corruption case on Tuesday afternoon, dramatically raising the stakes in a tense standoff between the government and its opponents.

The court order came as an enigmatic preacher turned politician, Muhammad Tahir ul Qadri, addressed thousands of supporters outside parliament and repeated calls for the ouster of the government. In earlier speeches, he said it should be replaced by caretaker administration led by technocrats. 

The confluence of the two events stoked growing speculation that Pakistan’s powerful military was quietly supporting moves that would delay general elections that are due to take place this spring, mostly likely through the imposition of a military-backed caretaker administration. 

“Victory, victory, victory. By the grace of God,” Mr. Qadri said at the conclusion of a speech to his supporters who were camped outside the parliament. Others, however, suggested that the court, led by the independent-minded chief justice Iftikhar Muhammad Chaudhry, was simply taking advantage of anti-government sentiment generated by Mr. Qadri as part of its long-standing grudge match against President Asif Ali Zardari’s government.

Whatever the motivations, the court’s actions added to the chaos in Pakistan, with the stock market dropping 3 percent after word of the court’s order came down.

In the order issued Tuesday, the Supreme Court told the National Accountability Bureau, a government body that investigates graft, to arrest Mr. Ashraf and 15 other senior serving or former officials, including a former finance minister and a former finance secretary.

The case relates to long-standing allegations that Mr. Ashraf took kickbacks from a deal to build electricity power plants while serving as minister for water and power between March 2008 and February 2011. Pakistan’s energy crisis, which has seen severe electricity rationing across the country, is one of the main sources of complaints against the government.

Mr. Ashraf has denied the accusations, while Mr. Zardari’s supporters have painted the prosecution as part of a politically-tinged drive by Justice Chaudhry to unseat Mr. Zardari. Mr. Ashraf came to power last summer after the supreme court forced his predecessor, Yousaf Raza Gilani, to resign from office over another corruption-related case.

Whether there was any link between the court order and Mr. Qadri’s march on

Islamabad – billed by the preacher as a “million man march” but in reality far smaller – the timing was certainly striking.

In his speech Mr. Qadri – who returned barely one month to Pakistan from Canada, where he also holds citizenship – demanded the immediate resignation of the government, and painted the country’s elected politicians as “criminals” who deserved to be prosecuted for corruption.

While stressing that he did not want a “derailment of democracy,” Mr. Qadri described the parliament as “fake” and vowed to bring a “green revolution, a peaceful revolution” in Pakistan.

“There is no Parliament. There is a group of looters, thieves and dacoits!” he said in a  thundering voice,  pointing to the building behind him. “Our lawmakers are the law breakers.

In contrast Mr. Qadri offered fulsome support for the military and the supreme court, both of which have been at odds with Mr. Zardari’s government at various points in recent years.  “Now only two institutions are there – the judiciary and the armed forces,” he said.

There was no immediate response from the government, whose term ends in mid-March. Under the constitution, elections are due to take place within the following 60 days.
