India Ink: Air Pollution in New Delhi Was Much Worse Than Beijing Thursday, But Indian Government Is Not Acting

Manish Swarup/Associated Press A thick blanket of smog over New Delhi on Thursday morning.

NEW DELHI—Beijing’s air pollution has reached such toxic levels recently that the Chinese government is finally acknowledging the problem – and acting on it.

But in New Delhi on Thursday, air pollution levels far exceeded those in Beijing, only without any government acknowledgement or action. It is not the first time pollution in India’s capital has outpaced that in China.

The level of tiny particulates known as PM 2.5, which lodge deep in the lungs and can enter the bloodstream, was over 400 micrograms per cubic meter in various neighborhoods in and around Delhi Thursday, according to a real-time air quality monitor. That compared to Beijing’s most-recent air quality reading of 172 micrograms per cubic meter. (The “Air Quality online” link to the left of the Delhi website gives you real-time monitoring of Delhi’s pollution levels.)

At the University of Delhi’s northern campus at 12:30 p.m., the reading for PM 2.5 was 402 micrograms per cubic meter; in the eastern suburb of Noida it was 411; at the Indira Gandhi International airport it was 421.

Beijing’s government on Wednesday introduced emergency measures to curb pollution, ordering cars off the roads and factories to shut down, and warning citizens to avoid activity outside. The measures came after two straight days that the readings were higher than 300, a level the United States Environmental Protection Agency considers “hazardous.”

The forecast for Delhi’s air pollution Friday is “critical,” according to the Ministry of Earth Sciences. So far, though, Delhi’s government has made no announcements about the city’s air pollution, nor introduced any emergency measures, a spokesman for chief minister’s office said. Sheila Dikshit, the chief minister, said in an interview in December that the city could not keep up with the factors that cause air pollution.

Beijing’s air quality is so bad that living there is like living in a smoking lounge, Bloomberg reported Wednesday. The levels of air pollution Bloomberg cited as Beijing’s average were half that of New Delhi early Thursday afternoon.

Dr. Phil says Manti Te’o hoaxer admits to love for linebacker

LOS ANGELES (Reuters) – A California man who has admitted to fabricating Notre Dame linebacker Manti Te‘o’s fake girlfriend in an elaborate hoax told talk show host Phil McGraw he felt a deep romantic love for the football player, McGraw said on Wednesday.

“Here we have a young man that fell deeply, romantically in love,” McGraw told the television morning show “Today” to discuss his two part interview with Ronaiah Tuiasosopo, which will air on “Dr. Phil” on Thursday and Friday.

“I asked him straight up, ‘Was this a romantic relationship with you?,’ and he says yes. I said, ‘Are you then therefore gay?’ And he said, ‘When you put it that way, yes.’ And then he caught himself and said, ‘I am confused,’” McGraw told “Today.”

Te’o has said in a previous media interview he is not gay.

The fake girlfriend hoax involving Te’o, who was a finalist for college football’s highest individual honor the Heisman trophy, caused a sensation when it was revealed earlier this month on news website Deadspin.com.

Tuiasosopo says he played the part over the phone of Lennay Kekua, the fictitious woman who was Te’o's girlfriend in the hoax. Te’o, 22, had spoken about the woman in media interviews, and reports described her surviving a car accident and then dying of leukemia in September.

Te’o has said since the hoax was exposed that he was the victim of an elaborate prank, that he never met Kekua and that his acquaintance Tuiasosopo admitted to him that he was the one who played the part of Lennay.

Dr. Phil said in a segment on “Today” on Wednesday that after an extensive interview with Tuiasosopo, he believes Te’o had no role in creating the hoax.

“Absolutely, unequivocally, no,” McGraw said, in pinning the blame for the scheme on Tuiasosopo.

The NBC morning program also showed some comments Tuiasosopo made in his interview for the “Dr. Phil” daytime program.

“There are many times where Manti and Lennay had broken up,” Tuiasosopo told “Dr. Phil.”

“But something would bring them back together, whether it was something going on in his life or in Lennay’s life, in this case in my life,” Tuiasosopo said.

Tuiasosopo, 22, is from southern California and played high school football in 2005 at Antelope Valley High north of Los Angeles, according to media reports. Tuaisosopo’s attorney had previously told reporters his client was behind the hoax.

Before the hoax was exposed, a photo of a woman who was described as Lennay Kekua was presented in media reports about Te’o and his struggles to overcome her death and that of his grandmother, who actually did pass away.

But the photo of Kekua was taken from a Facebook profile of a California woman who said she was unaware of the scheme, according to Deadspin.com.

Te’o told Katie Couric in a broadcast of her show “Katie” last week that he received a telephone call from the person claiming to be Kekua on December 6 – two days before the Heisman presentation. But he said he was not really certain she never existed until Tuiasosopo’s later confession to him.

The linebacker, during the Katie Couric interview, presented a voice mail he received from the person he said he thought was Kekua. “Doesn’t that sound like a girl?” Te’o told Couric.

Te’o also told Couric he is not gay. “No, far from it,” he said.

2 NFL seasons since agreement, still no HGH tests

NEW ORLEANS (AP) — Count Baltimore Ravens defensive end Arthur Jones among those NFL players who want the league and the union to finally agree on a way to do blood testing for human growth hormone.

"I hope guys wouldn't be cheating. That's why you do all this extra work and extra training. Unfortunately, there are probably a few guys, a handful maybe, that are on it. It's unfortunate. It takes away from the sport," Jones said.

"It would be fair to do blood testing," Jones added. "Hopefully they figure it out."

When Jones and the Ravens face the San Francisco 49ers in the Super Bowl on Sunday, two complete seasons will have come and gone without a single HGH test being administered, even though the league and the NFL Players Association paved the way for it in the 10-year collective bargaining agreement they signed in August 2011.

Since then, the sides have haggled over various elements, primarily the union's insistence that it needs more information about the validity of a test that is used by Olympic sports and Major League Baseball. HGH is a banned performance-enhancing drug that is hard to detect and has been linked to health problems such as diabetes, cardiac dysfunction and arthritis.

"If there are guys using (HGH), there definitely needs to be action taken against it, and it needs to be out of (the sport)," Ravens backup quarterback Tyrod Taylor said. "I'm pretty sure it'll happen eventually."

At least two members of Congress want to make it happen sooner, rather than later.

House Oversight and Government Reform Committee chairman Darrell Issa, a California Republican, and ranking Democrat Elijah Cummings of Maryland wrote NFLPA head DeMaurice Smith this week to chastise the union for standing in the way of HGH testing and to warn that they might ask players to testify on Capitol Hill.

Smith is scheduled to hold his annual pre-Super Bowl news conference Thursday.

"We have cooperated and been helpful to the committee on all of their requests," NFLPA spokesman George Atallah said. "If this is something they feel strongly about, we will be happy to help them facilitate it."

Several players from the Super Bowl teams said they would be willing to talk to Congress about the issue, if asked.

"I have nothing to hide. I can't speak for anyone else in football, but I would have no problem going," said Kenny Wiggins, a 6-foot-6, 314-pound offensive lineman on San Francisco's practice squad.

But Wiggins added: "There's a lot more problems in the U.S. they should be worried about than HGH in the NFL."

That sentiment was echoed by former New York Giants offensive lineman Shaun O'Hara, who now works for the NFL Network.

"Do I think there is an HGH problem in the NFL? I don't think there is. Are there guys who are using it? I'm sure there are. But is it something Congress needs to worry about? No. We have enough educated people on both sides that can fully handle this. And if they can't, then they should be fired," said O'Hara, an NFLPA representative as a player. "I include the union in that, and I include the NFL. There is no reason we would need someone to help us facilitate this process."

Issa and Cummings apparently disagree.

In December, their committee held a hearing at which medical experts testified that the current HGH test is reliable and that the union's request for a new study is unnecessary. Neither the league nor union was invited to participate in that hearing; at the time, Issa and Cummings said they expected additional hearings.

"We are disappointed with the NFLPA's remarkable recalcitrance, which has prevented meaningful progress on this issue," they wrote in their recent letter to Smith. "We intend to take a more active role to determine whether the position you have taken — that HGH is not a serious concern and that the test for HGH is unreliable — is consistent with the beliefs of rank and file NFL players."

Atallah questioned that premise.

"To us, there is no distinction between players and the union. ... The reason we had HGH in our CBA is precisely because our players wanted us to start testing for it," Atallah said. "We are not being recalcitrant for recalcitrance sake. We are merely following the direction of our player leadership."

Wiggins and other players said no one can know for sure how much HGH use there is in the league until there is testing — but that it's important for the union's concerns about the test to be answered.

"The union decides what is best for the players," said Ravens nose tackle Ma'ake Kemoeatu, who said he would be willing to go to Capitol Hill.

"I feel like some guys are on HGH," said 49ers offensive lineman Anthony Davis, who would rather not speak to Congress. "I personally don't care if there is testing. It's something they have to live with, knowing they cheated, and if they get (outplayed) while they're on it, it's a hit on their pride."

Well: Waiting for Alzheimer's to Begin

My gray matter might be waning. Then again, it might not be. But I swear that I can feel memories — as I’m making them — slide off a neuron and into a tangle of plaque. I steel myself for those moments to come when I won’t remember what just went into my head.

I’m not losing track of my car keys, which is pretty standard in aging minds. Nor have I ever forgotten to turn off the oven after use, common in menopausal women. I can always find my car in the parking lot, although lots of “normal” folk can’t.

Rather, I suddenly can’t remember the name of someone with whom I’ve worked for years. I cover by saying “sir” or “madam” like the Southerner I am, even though I live in Vermont and grown people here don’t use such terms. Better to think I’m quirky than losing my faculties. Sometimes I’ll send myself an e-mail to-do reminder and then, seconds later, find myself thrilled to see a new entry pop into my inbox. Oops, it’s from me. Worse yet, a massage therapist kicked me out of her practice for missing three appointments. I didn’t recall making any of them. There must another Nancy.

Am I losing track of me?

Equally worrisome are the memories increasingly coming to the fore. Magically, these random recollections manage to circumnavigate my imagined build-up of beta-amyloid en route to delivering vivid images of my father’s first steps down his path of forgetting. He was the same age I am now, which is 46.

“How old are you?” I recall him asking me back then. Some years later, he began calling me every Dec. 28 to say, “Happy birthday,” instead of on the correct date, Dec. 27. The 28th had been his grandmother’s birthday.

The chasms were small at first. Explainable. Dismissible. When he crossed the street without looking both ways, we chalked it up to his well-cultivated, absent-minded professor persona. But the chasms grew into sinkholes, and eventually quicksand. When we took him to get new pants one day, he kept trying on the same ones he wore to the store.

“I like these slacks,” he’d say, over and over again, as he repeatedly pulled his pair up and down.

My dad died of Alzheimer’s last April at age 73 — the same age at which his father succumbed to the same disease. My dad ended up choosing neurology as his profession after witnessing the very beginning of his own dad’s forgetting.

Decades later, grandfather’s atrophied brain found its way into a jar on my father’s office desk. Was it meant to be an ever-present reminder of Alzheimer’s effect? Or was it a crystal ball sent to warn of genetic fate? My father the doctor never said, nor did he ever mention, that it was his father’s gray matter floating in that pool of formaldehyde.

Using the jarred brain as a teaching tool, my dad showed my 8-year-old self the difference between frontal and temporal lobes. He also pointed out how brains with Alzheimer’s disease become smaller, and how wide grooves develop in the cerebral cortex. But only after his death — and my mother’s confession about whose brain occupied that jar — did I figure out that my father was quite literally demonstrating how this disease runs through our heads.

Has my forgetting begun?

I called my dad’s neurologist. To find out if I was in the earliest stages of Alzheimer’s, he would have to look for proteins in my blood or spinal fluid and employ expensive neuroimaging tests. If he found any indication of onset, the only option would be experimental trials.

But documented confirmation of a diseased brain would break my still hopeful heart. I’d walk around with the scarlet letter “A” etched on the inside of my forehead — obstructing how I view every situation instead of the intermittent clouding I currently experience.

“You’re still grieving your father,” the doctor said at the end of our call. “Sadness and depression affect the memory, too. Let’s wait and see.”

It certainly didn’t help matters that two people at my father’s funeral made some insensitive remarks.

“Nancy, you must be scared to death.”

“Is it hard knowing the same thing probably will happen to you?”

Maybe the real question is what to do when the forgetting begins. My dad started taking 70 supplements a day in hopes of saving his mind. He begged me to kill him if he wound up like his father. He retired from his practice and spent all day in a chair doing puzzles. He stopped making new memories in an all-out effort to preserve the ones he already had.

Maybe his approach wasn’t the answer.

Just before his death — his brain a fraction of its former self — my father managed to offer up a final lesson. I was visiting him in the memory-care center when he got a strange look on his face. I figured it was gas. But then his eyes lit up and a big grin overtook him, and he looked right at me and said, “Funny how things turn out.”

An unforgettable moment?

I can only hope.

Royal Dutch Shell Posts $5.6 Billion Profit

LONDON — Royal Dutch Shell, Europe’s largest oil company, disappointed the markets Thursday with fourth-quarter earnings of $5.6 billion after one-time items and inventory changes.

The results were 15 percent above the previous year but well below analysts’ expectation of around $6.3 billion.

Stuart Joyner, an analyst at Investec Securities in London, described the results as “a substantial miss.” Shell’s stock price was down about 1 percent in morning trading in London.

The company’s earnings for the year were $25.1 billion, up 2 percent over 2011.

The disappointment was largely due to lower earnings in Shell’s core exploration and production business, mainly because of weak performance in the Americas, where Shell’s multibillion Alaska drilling program has encountered multiple snafus and delays.

Exploration and production earnings were $4.4 billion compared to $5.1 billion the previous year, with the U.S. exploration and production business reporting a $69 million loss, partly due to low natural gas prices.

In another disappointment Shell estimated that it only replaced 44 percent of the reserves of oil and gas that it produced in 2012. That indicated that the company’s exploration effort, despite increased emphasis and spending in recent years, is still not performing well.

The capital investment forecast for 2013 was increased by 10 percent to $33 billion — another worry for the markets, as it suggests that Shell may be having trouble controlling costs.

On the positive side, Shell’s huge Pearl gas-to-liquids plant in Qatar is now fully operational and adding a hefty 235,000 barrels per day of oil equivalent to Shell’s production for the quarter.

Shell said that it was likely to increase its dividend in the first quarter of 2013 to 45 cents a share, a 4.7 percent increase over the first quarter of 2012.

“Shell is competitive and innovative,” the company’s chief executive, Peter Voser, said in a statement. “We are delivering on a strategy that others can’t easily repeat.”

Shell also had cause for relief on Wednesday when a court in The Hague dismissed most aspects of lawsuits brought against it by Nigerian farmers and fishermen seeking damages for pollution from oil spills in the Niger Delta.

French Forces Pressing Mali Campaign Seize Rebel Stronghold

BAMAKO, Mali — French troops took control overnight of the airport at the last major northern Mali town still in rebel hands, officials said on Wednesday, after Islamist militants abandoned two other principal settlements in the vast, desert region where residents’ relief and elation has given way to some measure of reprisal and frustration.

A French military spokesman in Paris, Col. Thierry Burkhard, said French troops reached the airport at Kidal, in the remote northeast of Mali, in an ongoing operation that is ongoing.

Haminy Maiga, a local official, told news agencies that French forces met no resistance when they arrived aboard four airplanes that landed late on Tuesday. France also sent helicopters, he said.

Kidal is the capital of a desert region of the same name. Secular Tuareg rebels claim to be in control of the town after Islamists fled. A newly formed Islamist splinter group that broke with the main Ansar Dine Islamist force also claims to have a power base there.

The new group calls itself the Islamic Movement for the Azawad and is led by Alghabass Ag Intalla, a prominent leader of the Tuareg ethnic group from the Kidal region who has said he wants to negotiate a settlement with the central government in Bamako, 800 miles to the southwest. Azawad is a Tuareg term for northern Mali.

Mali has been in turmoil since early 2012, when junior officers in the south staged a coup to protest the government’s tepid response to an uprising in the north by Tuareg separatists who were subsequently pushed to the side by Islamic extremists bent on imposing an extreme form of Shariah law.

Earlier this month, the Islamists suddenly advanced toward the capital, threatening to engulf the south, topple the weak central government and destabilize a vast area of northern Africa.

After a series of punishing French airstrikes in recent days, French and Malian troops launched a lightning campaign on the ground, entering the northern towns of Gao and Timbuktu as Islamist rebels seemed to melted away to far-flung hide-outs, possibly in the Kidal Province.

In Gao, groups of residents were reported on Tuesday to be hunting down suspected fighters who had not fled ahead of the French-Malian military forces who took control of the town over the weekend. Other residents expressed concern that Gao remained unsafe and was acutely short of food and fuel after a prolonged isolation.

“The city is free, but I think the areas close by are still dangerous,” said Mahamane Touré, a Gao resident reached by telephone from Bamako, the capital. “These guys are out there.”

Mr. Touré, who spent the evening watching soccer on television and listening to music with friends, said that although everyone was enjoying the new freedoms, the legacy of Islamist occupation was evident in the hardship of everyday life.

“The price of gasoline is almost double, and the price of food is very high,” Mr. Touré said. “There are still things in the market, but no one has any money and there is no aid.”

Reporters and photographers in Timbuktu, the storied desert oasis farther north that the French-Malian forces secured on Monday, saw looters pillaging shops and other businesses, with some saying the merchants were mainly Arabs, Mauritanians and Algerians who had supported the Islamist radicals who summarily executed, stoned and mutilated people they suspected of being nonbelievers during their 10-month occupation.

Alex Crawford, a television correspondent for Britain’s Sky News, said, “This is months and months of frustration and repression finally erupting.”

The rapidly shifting developments came less than three weeks into the military effort led by France, the former colonial power whose helicopters and warplanes began arriving here at the Malian government’s invitation on Jan. 11. Since then other West African countries have started to send troops. Britain is preparing to send more than 300 military trainers, and the United States is providing aerial cargo and refueling help.

In Washington, Pentagon officials said that as of Tuesday 17 sorties by United States Air Force C-17 cargo jets had flown 500 French troops and 390 tons of equipment into Bamako. In addition, there has been one aerial refueling operation by an American KC-135 tanker aircraft, which provided 33,000 pounds of fuel to several French warplanes, the officials said.

At the same time, a meeting of international donors was getting under way on Tuesday in Addis Ababa, Ethiopia, as part of an effort to provide more than $450 million in long-term financing for the military intervention in Mali.

The French-led effort has met surprisingly little resistance from the array of Islamist militias that occupied the northern part of Mali, an area about twice the size of Germany, in the spring of 2012 in the midst of a national political crisis.

It remains unclear how long the foreign military occupation will last. Most of the Islamist fighters have melted into the desert and could be regrouping to fight again.

In a bid to consolidate the gains, troops from Mali and neighboring Niger arrived Tuesday in the small town of Ansongo, about 50 miles south of Gao, one day after President François Hollande of France urged African countries to take a more prominent role in the operations.

Just as in Gao two days before, residents filled the streets there to greet the arrival of the African troops as they toured Ansongo and its environs.

“Everyone is very, very, very happy,” said Ibrahim Haidara, an Ansongo resident reached by phone. “They chanted, ‘Vive la France!’ and ‘Long live African armies!’ ”

But like his counterparts in Gao, he worried that the fighters might not have gone very far.

“They are in the bush. They are hiding,” he said. “One must be careful.”

Peter Tinti reported from Bamako, Rick Gladstone from New York, and Alan Cowell from London. Scott Sayare contributed reporting from Paris, John F. Burns from London, and Elisabeth Bumiller from Washington.

Facebook Graph Search Still Doesn’t Speak Human

Despite hiring a couple of linguists to get its new search engine to move “beyond ‘Robospeak” and actually understand how people talk, Facebook hasn’t actually taught Graph Search how to do that very well just yet. And that’s a problem, no matter which way the social network spins it. Unlike Google‘s pattern-matching search engine, Facebook’s new recommendation-based social search platform tries to understand full sentences. And that takes context, something that’s very hard to teach even the smartest computers, as one of the linguists that worked on the project, Amy Campbell, told The New York Times‘s Somini Sengupta. 

RELATED: Why Facebook’s Graph Search Can’t Give Users What They’re Looking for… Yet

In order to think more like a person the Graph Search team taught the engine 25 synonyms for “student” so that when someone types in “Stanford Academics that work at Facebook” the engine knows to look for “students” — 275,000 different ways in fact. But it turns out that an English class isn’t the future of machine learning: a grammar and vocabulary lesson proves a lot easier than complex sentient thoughts, and that’s where Facebook’s new product breaks down in practice.

RELATED: Why Google Isn’t Scared of Facebook’s Graph Search

For example, Graph Search doesn’t get vague pronouns. My query today for “photos Elle Reeve likes that she commented on” confuses Facebook’s beyond-robo engine. Instead, Graph Search results track down photos that my Atlantic Wire colleague “likes” but that I commented on:

RELATED: The Bad News-Good News of Tech Trademark Infringement

But Facebook’s ambiguity problem extends beyond “I” and “she.” Graph Search also has problems with double entendres, or sentences with nuance. The phrase “sports fans that like Lady Gaga play” has multiple meanings, notes the Times, especially because the word “fan” has its own special meaning on Facebook. (People with “Pages” have “fans.”) 

It’s not impossible to fix these specific issues. Facebook can add more relevant “context” to Graph Search as more people use it (beta testing rolled out over the last week). But never once has a machine perfectly understood our natural language. IBM’s Watson has come close, but it still made an embarrassing mistake every so often, and newer robots like Georgia Tech’s Simon are still getting there. Messups are okay (and entertaining) for a computer on a gameshow, or robots that might end up really helping bridge the computer-human divide. But, if I’m really going to use Graph Search as a way to find things in my day-to-day life, right now, those kind of hiccups should happen rarely to never — and Facebook’s slow phase-in excuse isn’t cutting it. If Graph Search can’t understand what humans want, it’s simply not doing its job.

A-Rod implicated in PED use again as MLB probes

NEW YORK (AP) — Alex Rodriguez is in the middle of Major League Baseball's latest doping investigation after an alternative weekly newspaper reported baseball's highest-paid star was among the big leaguers listed in the records of a Florida clinic the paper said sold performance-enhancing drugs.

The Miami New Times said Tuesday that the three-time AL MVP bought human growth hormone and other performance-enhancing substances during 2009-12 from Biogenesis of America LLC, a now-closed anti-aging clinic in Coral Cables, Fla., near Rodriguez's offseason home.

The new public relations firm for the New York Yankees third baseman issued a statement denying the allegations.

New Times said it obtained records detailing purchases by Rodriguez, 2012 All-Star game MVP Melky Cabrera, 2005 AL Cy Young Award winner Bartolo Colon and 2011 AL championship series MVP Nelson Cruz of Texas.

Cabrera left San Francisco after the season to sign with Toronto, while Oakland re-signed Colon.

Other baseball players the newspaper said appeared in the records include Washington pitcher Gio Gonzalez, who finished third in last year's NL Cy Young Award voting, and San Diego catcher Yasmani Grandal.

Biogenesis, which the New Times said was run by Anthony Bosch, was located in a beige, nondescript office park. The former clinic is no longer listed as a business in its directory,

"There was a flier put out by the building management a couple weeks ago. It was put on all the doors and windows of all the offices," said Brad Nickel, who works in a cruise planning company on the floor above where the clinic was located. "It just said this guy's not really a doctor, he doesn't belong here, he's no longer allowed here, call the police or the building management if you see him."

The New Times posted copies of what it said were Bosch's handwritten records, obtained through a former Biogenesis employee it did not identify.

Bosch's lawyer, Susy Ribero-Ayala, said in a statement the New Times report "is filled with inaccuracies, innuendo and misstatements of fact."

"Mr. Bosch vehemently denies the assertions that MLB players such as Alex Rodriguez and Gio Gonzalez were treated by or associated with him," she said.

Rodriguez appears 16 times in the documents New Times received, the paper said, either as "Alex Rodriguez," ''Alex Rod" or the nickname "Cacique," a pre-Columbian Caribbean chief.

Rodriguez admitted four years ago that he used PEDs from 2001-03. Cabrera, Colon and Grandal were suspended for 50 games each last year by MLB following tests for elevated testosterone. Responding to the testosterone use, MLB and the players' union said Jan. 10 they were authorizing the World Anti-Doping Agency laboratory outside Montreal to store each major leaguer's baseline testosterone/epitestosterone (T/E) ratio in order to detect abnormalities.

"We are always extremely disappointed to learn of potential links between players and the use of performance-enhancing substances," MLB said in a statement. "Only law enforcement officials have the capacity to reach those outside the game who are involved in the distribution of illegal performance-enhancing drugs. ... We are in the midst of an active investigation and are gathering and reviewing information."

A baseball official, speaking on condition of anonymity because he was not authorized to make public statements, said Monday that MLB did not have any documentation regarding the allegations. If MLB does obtain evidence, the players could be subject to discipline. First offenses result in a 50-game suspension and second infractions in 100-game penalties. A third violation results in a lifetime ban.

Rodriguez is sidelined for at least the first half of the season after hip surgery Jan. 16. A 50-game suspension would cost him $7.65 million of his $28 million salary.

"The news report about a purported relationship between Alex Rodriguez and Anthony Bosch are not true," Rodriguez said in a statement issued by a publicist. "He was not Mr. Bosch's patient, he was never treated by him and he was never advised by him. The purported documents referenced in the story — at least as they relate to Alex Rodriguez — are not legitimate."

Jay Reisinger, a lawyer who has represented Rodriguez in recent years, said the three-time AL MVP had retained Roy Black, an attorney from Rodriguez's hometown of Miami. Black's clients have included Rush Limbaugh and William Kennedy Smith.

Bosch did not return a phone message seeking comment.

MLB hopes to gain the cooperation of Bosch and others connected with the clinic, another baseball official said, also on condition of anonymity because no public statements on the matter were authorized. In order to successfully discipline players based on the records, witnesses would be needed to authenticate them, the official said.

Players could be asked to appear before MLB for interviews, but the official said MLB would be reluctant to request interviews before it has more evidence.

Rodriguez spent years denying he used PEDs before Sports Illustrated reported in February 2009 that he tested positive for two steroids in MLB's anonymous survey while with the Texas Rangers in 2003. Two days later, he admitted in an ESPN interview that he used PEDs over a three-year period. He has denied using PEDs after 2003.

If the new allegations were true, the Yankees would face high hurdles to get out of the final five years and $114 million of Rodriguez's record $275 million, 10-year contract. Because management and the players' union have a joint drug agreement, an arbitrator could determine that any action taken by the team amounted to multiple punishments for the same offense.

But if Rodriguez were to end his career because of the injury, about 85 percent of the money owed by the Yankees would be covered by insurance, one of the baseball officials said.

Gonzalez, 21-8 for the Washington Nationals last season, posted on his Twitter feed: "I've never used performance enhancing drugs of any kind and I never will, I've never met or spoken with tony Bosch or used any substance provided by him. anything said to the contrary is a lie."

Colon was not issuing a statement, agent Adam Katz said through spokeswoman Lisa Cohen.

"We are aware of certain allegations and inferences," Cruz's law firm, Farrell & Reisinger, said in a statement. "To the extent these allegations and inferences refer to Nelson, they are denied."

Cruz and Gonzalez had not previously been linked to performance-enhancing drugs. Cruz hit 24 home runs last year for the Rangers.

The New Times report said it obtained notes by Bosch listing the players' names and the substances they received. Several unidentified employees and clients confirmed to the publication that the clinic distributed the substances, the paper said. The employees said that Bosch bragged of supplying drugs to professional athletes but that they never saw the sports stars in the office.

The paper said the records list that Rodriguez paid for HGH; testosterone cream; IGF-1, a substance banned by baseball that stimulates insulin production; and GHRP, which releases growth hormones.

Well: Helmets for Ski and Snowboard Safety

Recently, researchers from the department of sport science at the University of Innsbruck in Austria stood on the slopes at a local ski resort and trained a radar gun on a group of about 500 skiers and snowboarders, each of whom had completed a lengthy personality questionnaire about whether he or she tended to be cautious or a risk taker.

The researchers had asked their volunteers to wear their normal ski gear and schuss or ride down the slopes at their preferred speed. Although they hadn’t informed the volunteers, their primary aim was to determine whether wearing a helmet increased people’s willingness to take risks, in which case helmets could actually decrease safety on the slopes.

What they found was reassuring.

To many of us who hit the slopes with, in my case, literal regularity — I’m an ungainly novice snowboarder — the value of wearing a helmet can seem self-evident. They protect your head from severe injury. During the Big Air finals at the Winter X Games in Aspen, Colo., this past weekend, for instance, 23-year-old Icelandic snowboarder Halldor Helgason over-rotated on a triple back flip, landed head-first on the snow, and was briefly knocked unconscious. But like the other competitors he was wearing a helmet, and didn’t fracture his skull.

Indeed, studies have concluded that helmets reduce the risk of a serious head injury by as much as 60 percent. But a surprising number of safety experts and snowsport enthusiasts remain unconvinced that helmets reduce overall injury risk.

Why? A telling 2009 survey of ski patrollers from across the country found that 77 percent did not wear helmets because they worried that the headgear could reduce their peripheral vision, hearing and response times, making them slower and clumsier. In addition, many worried that if they wore helmets, less-adept skiers and snowboarders might do likewise, feel invulnerable and engage in riskier behavior on the slopes.

In the past several years, a number of researchers have attempted to resolve these concerns, for or against helmets. And in almost all instances, helmets have proved their value.

In the Innsbruck speed experiment, the researchers found that people whom the questionnaires showed to be risk takers skied and rode faster than those who were by nature cautious. No surprise.

But wearing a helmet did not increase people’s speed, as would be expected if the headgear encouraged risk taking. Cautious people were slower than risk-takers, whether they wore helmets or not; and risk-takers were fast, whether their heads were helmeted or bare.

Interestingly, the skiers and riders who were the most likely, in general, to don a helmet were the most expert, the men and women with the most talent and hours on the slopes. Experience seemed to have taught them the value of a helmet.

Off of the slopes, other new studies have brought skiers and snowboarders into the lab to test their reaction times and vision with and without helmets. Peripheral vision and response times are a serious safety concern in a sport where skiers and riders rapidly converge from multiple directions.

But when researchers asked snowboarders and skiers to wear caps, helmets, goggles or various combinations of each for a 2011 study and then had them sit before a computer screen and press a button when certain images popped up, they found that volunteers’ peripheral vision and reaction times were virtually unchanged when they wore a helmet, compared with wearing a hat. Goggles slightly reduced peripheral vision and increased response times. But helmets had no significant effect.

Even when researchers added music, testing snowboarders and skiers wearing Bluetooth-audio equipped helmets, response times did not increase significantly from when they wore wool caps.

So why do up to 40 percent of skiers and snowboarders still avoid helmets?

“The biggest reason, I think, is that many people never expect to fall,” says Dr. Adil H. Haider, a trauma surgeon and associate professor of surgery at Johns Hopkins University in Baltimore and co-author of a major new review of studies related to winter helmet use. “That attitude is especially common in people, like me, who are comfortable on blue runs but maybe not on blacks, and even more so in beginners.”

But a study published last spring detailing snowboarding injuries over the course of 18 seasons at a Vermont ski resort found that the riders at greatest risk of hurting themselves were female beginners. I sympathize.

The takeaway from the growing body of science about ski helmets is in fact unequivocal, Dr. Haider said. “Helmets are safe. They don’t seem to increase risk taking. And they protect against serious, even fatal head injuries.”

The Eastern Association for the Surgery of Trauma, of which Dr. Haider is a member, has issued a recommendation that “all recreational skiers and snowboarders should wear safety helmets,” making them the first medical group to go on record advocating universal helmet use.

Perhaps even more persuasive, Dr. Haider has given helmets to all of his family members and colleagues who ski or ride. “As a trauma surgeon, I know how difficult it is to fix a brain,” he said. “So everyone I care about wears a helmet.”

BlackBerry 10’s Debut Is a Critical Day for Research in Motion

OTTAWA — Research in Motion’s introduction on Wednesday of a new BlackBerry phone will be the most important event in the company’s history since 1996, when its founders showed investors a small block of wood and promised that a wireless e-mail device shaped like that would change business forever.

Now with just 4.6 percent of the global market for smartphones in 2012, according to IDC, RIM long ago exchanged dominance for survival mode. On Wednesday, the company will introduce a new line of smartphones called the BlackBerry 10 and an operating system of the same name that Thorsten Heins, the president and chief executive of RIM, says will restore the company to glory.

But Frank Mersch, who became one of RIM’s earliest investors after seeing the block of wood, is far less excited by what he sees this time around.

“You’re in a very, very competitive market and you’re not the leader,” Mr. Mersch, now the chairman and a vice president at Front Street Capital in Toronto, said of RIM. “You have to ask: ‘At the end of the day are we really going to win?’ I personally think the jury’s out on that.”

The main elements of the new phones and their operating system are already well known. Mr. Heins and other executives at RIM have been demonstrating the units for months to a variety of audiences. App developers received prototype versions as far back as last spring.

While analysts and app developers may be divided about the future of RIM, there is a consensus that BlackBerry 10, which arrives more than year behind schedule, was worth the wait.

Initially RIM will release two variations of the BlackBerry 10, one a touch-screen model that resembles many other phones now on the market. The other model is a hybrid with a keyboard similar to those now found on current BlackBerrys as well as a small touch screen.

The real revolution, though, may be in the software that manages a person’s business and personal information. It is clearly designed with an eye toward retaining and, more important, luring back, corporate users.

Corporate and government information technology managers will be able to segregate business-related apps and data on BlackBerry 10 handsets from users’ personal material through a system known as BlackBerry Balance. It will enable an I.T. manager to, among other things, remotely wipe corporate data from fired employees’ phones while leaving the newly jobless workers’ personal photos, e-mails, music and apps untouched. The system can also block users from forwarding or copying information from the work side of the phone.

Messages generated by e-mail, Twitter, Facebook, instant messaging and LinkedIn accounts are automatically consolidated into a single in-box that RIM calls BlackBerry Hub.

Charles Golvin, an analyst with Forrester Research, called the new phones “beautiful” and described the operating system as “a giant leap forward” from RIM’s current operating system. Ray Sharma, who followed RIM’s glory years as a financial analyst but who now runs XMG Studio, a mobile games developer in Toronto, has been similarly impressed.

But both men are among many analysts who question the ability of BlackBerry 10, whatever its merits, to revive RIM’s fallen fortunes.

“If it’s good, it will help inspire the upgrade cycle,” Mr. Sharma said. “But it has to be great in order to inspire touch-screen users to come back. If it’s good, not great, I will be concerned.”

Mr. Golvin was more blunt. “They’ll need to prove themselves in the face of a simultaneous onslaught of marketing from Microsoft, not to mention the continued push from Apple plus Google and its Android partners,” he wrote. “This is a gargantuan challenge for a company of RIM’s size.”

In the year since he took over from the founders, Jim Balsillie and Mike Lazaridis, Mr. Heins has certainly remade RIM. He cut 5,000 jobs in a program to reduce operating costs by about $1 billion a year. Along the way, he also replaced RIM’s senior management and straightened out its balance sheet. While unprofitable, RIM remains debt-free and holds $2.9 billion in cash.

With BlackBerry 10, RIM not only started over with its operating system, it also rebuilt the company through acquisitions. Its core operating system comes from QNX Software Systems, the design of the user interface is largely the work of the Astonishing Tribe in Sweden while other main components, like the touch-screen technology, came from smaller companies that are now part of RIM.

Integrating all of those acquisitions, analysts and former RIM employees say, added to the delays that plagued BlackBerry 10.

Now that the new phones are finally here, Mr. Heins is counting on RIM’s remaining base of 79 million users globally to eagerly upgrade. But where those customers reside may be as important in their numbers in determining the success of that plan.

In the United States, which leads the world in setting smartphone trends, about 11 million BlackBerry users switched to other phones between 2009 and the middle of last year, according to an analysis by Horace Dediu on Asymco, a wireless industry blog he founded.

Until the final months of 2012, RIM continued to increase its subscriber base through sales of low-cost handsets to less developed countries like Nigeria and Indonesia. Although BlackBerry 10 will be made available worldwide, the initial phones will be too expensive for a majority of BlackBerry fans in those regions.

RIM may also have confused its loyalists, particularly in North America and Europe, in the run-up to the BlackBerry 10 debut. Many of those users stuck with BlackBerrys because of their physical keyboards. But public demonstrations for BlackBerry 10 were centered on the touch-screen-only version and its virtual keyboard.

While some corporations have remained loyal to BlackBerry, RIM not only has to sell them on the new handsets, it also must persuade them to upgrade server software to accommodate the new operating system, a costly and time-consuming process. Companies whose employees continue to use older BlackBerrys will have to run two separate BlackBerry servers.

Mr. Heins’s pitch to those corporations is that the BlackBerry 10 server software will also allow them to manage and control data on employees’ Android phones and iPhones. But any corporation or organization that allows those phones to connect with its systems long ago installed mobile device management software from other companies, including Good Technology and SAP. RIM is likely to find that the competition in device management software is as severe as it is in the handset business.
