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.

Chinese Hackers Infiltrate New York Times Computers





SAN FRANCISCO — For the last four months, Chinese hackers have persistently attacked The New York Times, infiltrating its computer systems and getting passwords for its reporters and other employees.







The New York Times published an article in October about the wealth of the family of China's prime minister, Wen Jiabao, in both English and Chinese.







After surreptitiously tracking the intruders to study their movements and help erect better defenses to block them, The Times and computer security experts have expelled the attackers and kept them from breaking back in.


The timing of the attacks coincided with the reporting for a Times investigation, published online on Oct. 25, that found that the relatives of Wen Jiabao, China’s prime minister, had accumulated a fortune worth several billion dollars through business dealings.


Security experts hired by The Times to detect and block the computer attacks gathered digital evidence that Chinese hackers, using methods that some consultants have associated with the Chinese military in the past, breached The Times’s network. They broke into the e-mail accounts of its Shanghai bureau chief, David Barboza, who wrote the reports on Mr. Wen’s relatives, and Jim Yardley, The Times’s South Asia bureau chief in India, who previously worked as bureau chief in Beijing.


“Computer security experts found no evidence that sensitive e-mails or files from the reporting of our articles about the Wen family were accessed, downloaded or copied,” said Jill Abramson, executive editor of The Times.


The hackers tried to cloak the source of the attacks on The Times by first penetrating computers at United States universities and routing the attacks through them, said computer security experts at Mandiant, the company hired by The Times. This matches the subterfuge used in many other attacks that Mandiant has tracked to China.


The attackers first installed malware — malicious software — that enabled them to gain entry to any computer on The Times’s network. The malware was identified by computer security experts as a specific strain associated with computer attacks originating in China. More evidence of the source, experts said, is that the attacks started from the same university computers used by the Chinese military to attack United States military contractors in the past.


Security experts found evidence that the hackers stole the corporate passwords for every Times employee and used those to gain access to the personal computers of 53 employees, most of them outside The Times’s newsroom. Experts found no evidence that the intruders used the passwords to seek information that was not related to the reporting on the Wen family.


No customer data was stolen from The Times, security experts said.


Asked about evidence that indicated the hacking originated in China, and possibly with the military, China’s Ministry of National Defense said, “Chinese laws prohibit any action including hacking that damages Internet security.” It added that “to accuse the Chinese military of launching cyberattacks without solid proof is unprofessional and baseless.”


The attacks appear to be part of a broader computer espionage campaign against American news media companies that have reported on Chinese leaders and corporations.


Last year, Bloomberg News was targeted by Chinese hackers, and some employees’ computers were infected, according to a person with knowledge of the company’s internal investigation, after Bloomberg published an article on June 29 about the wealth accumulated by relatives of Xi Jinping, China’s vice president at the time. Mr. Xi became general secretary of the Communist Party in November and is expected to become president in March. Ty Trippet, a spokesman for Bloomberg, confirmed that hackers had made attempts but said that “no computer systems or computers were compromised.”


Signs of a Campaign


The mounting number of attacks that have been traced back to China suggest that hackers there are behind a far-reaching spying campaign aimed at an expanding set of targets including corporations, government agencies, activist groups and media organizations inside the United States. The intelligence-gathering campaign, foreign policy experts and computer security researchers say, is as much about trying to control China’s public image, domestically and abroad, as it is about stealing trade secrets.


This article has been revised to reflect the following correction:

Correction: January 31, 2013

An earlier version of this article misstated the year that the United States and Israel were said to have started a cyber attack that caused damage at Iran’s main nuclear enrichment plant, and the article misstated the specific type of attack. The attack was a computer worm, not a virus, and it started around 2008, not 2012.

Israel to Transfer Tax Funds to Palestinians





JERUSALEM — Israel has decided to transfer tax and customs revenues collected last month on behalf of the Palestinian Authority to help ease the economic crisis there, a senior Israeli government official said on Wednesday.




This reverses an earlier decision to use the revenues to offset at least part of the Palestinian debts to Israeli utility companies as a punitive measure following the Palestinians’ successful bid to upgrade their status at the United Nations to that of a nonmember observer state in late November.


But the official emphasized that the decision was “a one-time event” and was “not an indication of what Israel might do next month.”


The decision to transfer the funds came after a meeting on Monday between Prime Minister Benjamin Netanyahu and Tony Blair, the envoy of the so-called quartet of Middle East peacemakers that groups the United States, the European Union, the United Nations and Russia. In a statement after the meeting, both men pledged to work on peace and security issues.


Nour Odeh, a spokeswoman for the Palestinian Authority, said that Palestinian and Israeli officials were scheduled to hold a regular technical meeting on Wednesday where they would calculate the amount of revenues collected and owed. Revenues usually amount to around $100 million a month.


The Palestinian Authority, a self-rule body with limited control over parts of the West Bank, has been in financial crisis for about two years, largely because of a drop in donor funds, and it has been struggling to pay its 150,000 government workers their full salaries on time, leading to growing restiveness and strikes.


Israel’s decision to withhold the transfers after the United Nations move was expected, but special funds pledged by Arab states to the authority as a so-called “safety net” after the diplomatic clash with Israel have not yet materialized.


Israel has withheld transfers of Palestinian tax revenues at least five times before, sometimes for weeks and, after the outbreak of the Palestinian uprising in 2000, for two years. But this was the first time that Israel had used the money, which constitutes about two-thirds of the authority’s income, to pay off Palestinian debts to the Israel Electric Corporation and other Israeli providers without the consent of the authority.


The prime minister of the Palestinian Authority, Salam Fayyad, called in December for a voluntary boycott of Israeli goods by Palestinian consumers in what he called a “logical response” to the Israeli measure because the tax revenues are accrued on Palestinian trade with Israel. The call did not appear have had much impact either in the Palestinian territories or on the Israeli economy.


Israel’s former foreign minister, Avigdor Lieberman, had said in December that it would take four months of tax revenues collected by Israel for the Palestinian Authority to repay its debts. He had threatened that no money would be transferred from Israel to the authority until the debts were paid.


In a statement released by the Palestinian Authority cabinet after a meeting on Tuesday, the withholding of tax revenues was described as “Israeli piracy.” The cabinet said that government workers would be paid the remaining half of their November salaries in the next two days, “if work is resumed in the ministries, at the least by those responsible for executing the salary payment procedures.”


The cabinet also “affirmed the urgency for our Arab brethren to accelerate the implementation of their commitments to support the state treasury,” according to the statement.


Israel is engaged in a delicate balancing act since it does not have an interest in seeing the Palestinian Authority collapse, officials there have said. In the weeks before the United Nations action, they said, Israel advanced money to the Palestinian Authority in response to calls for help and to provide some relief ahead of a Muslim holiday.

Critical, long-overdue BlackBerry makeover arrives






TORONTO (AP) — BlackBerry maker Research In Motion Ltd. will kick off a critical, long-overdue makeover when chief executive Thorsten Heins shows off the first phone with the new BlackBerry 10 system in New York on Wednesday.


Repeated delays have left the once-pioneering BlackBerry an afterthought in the shadow of Apple’s trend-setting iPhone and Google’s Android-driven devices. There has even been talk that the fate of the company that created the BlackBerry in 1999 is no longer certain.






Now, there’s some optimism. Previews of the BlackBerry 10 software have gotten favorable reviews on blogs. Financial analysts are starting to see some slight room for a comeback. RIM‘s stock has more than doubled to $ 15.66 from a nine-year low in September, though it’s still nearly 90 percent below its 2008 peak of $ 147.


RIM redesigned the system to embrace the multimedia, apps and touch-screen experience prevalent today. The company is promising a speedier device, a superb typing experience and the ability to keep work and personal identities separate on the same phone.


Most analysts consider a BlackBerry 10 success to be crucial for the company’s long-term viability. Doubts remain about the ability of BlackBerry 10 to rescue RIM.


“We’ll see if they can reclaim their glory. My sense is that it will be a phone that everyone says good things about but not as many people buy,” BGC Financial analyst Colin Gillis said.


Jefferies analyst Peter Misek called it a “great device” and said RIM does have some momentum just months after the Canadian company was written off for dead.


“Six months ago we talked to developers and carriers, and everybody was just basically saying ‘We’re just waiting for this to go bust,’” Misek said. “It was bad.”


The BlackBerry has been the dominant smartphone for on-the-go business people and crossed over to consumers. But when the iPhone came out in 2007, it showed that phones can do much more than email and phone calls. Suddenly, the BlackBerry looked ancient. In the U.S., according to research firm IDC, shipments of BlackBerry phones plummeted from 46 percent of the market in 2008 to 2 percent in 2012.


RIM promised a new system to catch up, using technology it got through its 2010 purchase of QNX Software Systems. RIM initially said BlackBerry 10 would come by early 2012, but then the company changed that to late 2012. A few months later, that date was pushed further, to early 2013, missing the lucrative holiday season. The holdup helped wipe out more than $ 70 billion in shareholder wealth and 5,000 jobs.


Although executives have been providing a glimpse at some of BlackBerry 10′s new features for months, Heins will finally showcase a complete system at Wednesday’s event. Devices will go on sale soon after that. The exact date and prices are expected Wednesday.


Regardless of BlackBerry 10′s advances, though, the new system will face a key shortcoming: It won’t have as many apps written by outside companies and individuals as the iPhone and Android. RIM has said it plans to launch BlackBerry 10 with more than 70,000 apps, including those developed for RIM’s PlayBook tablet, first released in 2011. Even so, that’s just a tenth of what the iPhone and Android offer. Popular service such as Instagram and Netflix won’t have apps on BlackBerry 10.


Gillis said he’ll be looking to see when RIM releases a keyboard version of the new phone. The first BlackBerry 10 phone will have only a touch screen. RIM has said a physical keyboard version will be released soon after. He said a delay could alienate RIM’s 79 million subscribers.


“The No. 1 feature that they like is the physical keyboard,” Gillis said.

A-Rod implicated in PED use again as MLB probes


NEW YORK (AP) — Alex Rodriguez was ensnared in a doping investigation once again Tuesday when an alternative weekly newspaper reported baseball's highest-paid star was among a half-dozen players listed in records of a Florida clinic the paper said sold performance-enhancing drugs.


The Miami New Times said 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.


The newspaper 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 group 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."


David Sierra, who works in his aunt's real estate office in the same building, kept a picture of the flier on his iPhone. He recognized the doctor in the picture from passing him in the hallway.


Sierra said while he never recognized any of the clients at the clinic, "there were always really nice cars in front — I'm not talking just Mercedes. Range Rovers, Bentleys."


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.


The Yankees said "this matter is now in the hands of the commissioner's office" and said they will not comment further until MLB's investigation ends.


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."


Sam and Seth Levinson, the agents for Cabrera, Cruz and Gonzalez, did not respond to emails seeking comment. Greg Genske, Grandal's agent, also did not reply to an email.


Cruz and Gonzalez had not previously been linked to performance-enhancing drugs. Cruz hit 24 home runs last year for the Texas Rangers, who says they notified MLB last week after being contacted by the New Times.


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.


Rodriguez's cousin, Yuri Sucart, also is listed as having purchased HGH. Sucart was banned from the Yankees clubhouse, charter flights, bus and other team-related activities by MLB in 2009 after Rodriguez said Sucart obtained and injected PEDs for him.


Also listed among the records, according to the New Times, are tennis player Wayne Odesnik, Cuban boxer Yuriorkis Gamboa and Jimmy Goins, the strength and conditioning coach of the University of Miami baseball team.


Odesnik, who lost in the first round of qualifying for this year's Australian Open, is a former top-100 player who was suspended by the International Tennis Federation after Australian customs officers found eight vials containing HGH in his luggage when he arrived in that country ahead of a January 2010 tournament. He denied using HGH and never tested positive for it. What originally was a two-year ban was cut in half because the ITF said Odesnik cooperated with its anti-doping program.


"The statement about Wayne's relationship with Mr. Bosch is completely false, and Wayne has contacted the reporter and newspaper for a retraction," the tennis player's mother, Janice Odesnik, wrote in an email to The Associated Press.


Mia Ro, a spokeswoman for the federal Drug Enforcement Administration in Miami, said she could not confirm or deny the existence of an investigation into Bosch or the clinic.


The University of Miami said it was conducting "an intensive review" of the matter but did not identify Goins by name.


Goins was "very surprised" to learn of the allegations raised by the New Times, according to a statement from Michelle A. White, of the Coral Gables law firm of Fenderson & Hampton, which said it was representing him.


White would not comment on whether Goins was a patient of Bosch but added that Goins "has done nothing improper either personally or as a representative of the University of Miami," and denies any allegation or inference of wrongdoing.

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.

IHT Rendezvous: Regulating the British Press

LONDON — News doesn’t just travel fast here. It happens fast, too. And once it has happened, new news overtakes the old: the dogs bark, as the old Middle Eastern adage has it, but the caravan moves on.

So it has seemed in the almost two months since the publication of the bulky Leveson Report into the culture and behavior of the British press. The land has been swamped by a procession of other front-page stories — British hostages in Algeria! Referendum on Europe! — and the urgency of Lord Justice Sir Brian Leveson’s call for statutory oversight of the rambunctious press here seems to have dissipated.

But a couple of developments in recent days have recalled some of the issues — quite apart from a steady trickle of arrests linked to the phone hacking and allied scandals that prompted the Leveson inquiry in the first place.

Page Two

Posts written by the IHT’s Page Two columnists.

One was the return from duty in Afghanistan of Prince Harry, the third in line to the British throne, who, as I describe in my latest column on Page Two of The International Herald Tribune, stirred a media frenzy by acknowledging that — no real surprise here — as the gunner co-pilot of an Apache attack helicopter, he was expected to fire on Taliban insurgents.

But there was a sub-plot.

Prince Harry’s aversion to the British media — equally unsurprising in light of the tangled relationship between his mother, Princess Diana, and the world’s newspapers, photographers and broadcasters — appears to be growing to the extent that he accused the British press of always writing “rubbish” about him.

A video report from Britain’s Channel 4 News shot during Prince Harry’s recent deployment to Afghanistan.

And yet, for the 20 weeks of Prince Harry’s deployment in Afghanistan, most news outlets in Britain had largely agreed with Buckingham Palace and the Ministry of Defense not to cover closely his role in the war, in return for guaranteed access at the end of his tour — a gesture of what the authorities would doubtless call responsibility on the part of that same press the prince dismissed.

The prince’s comments drew a tart response from Peter Barron, the editor of the regional Northern Echo. “It would have been nice if Prince Harry had resisted getting out his huge tar brush to blacken the entire British press and acknowledged that there are good and bad in every profession — including the armed forces,” he said.

The broader issue of how Britain regulates its media is still the object of closed-door talks among editors and executives and between politicians. But it could well resurface publicly next month.

“This is not about politicians determining what journalists do or do not write. The freedom of the press is essential,” Harriet Harman, the spokeswoman on media affairs for the opposition Labour Party, told a gathering in Oxford, England, last week. “But so is that other freedom: the freedom of a private citizen to go about their business without harassment, intrusion or the gross invasion of their grief and trauma. Those two freedoms are not incompatible.”

She challenged the government directly to set out its own proposals for the future regulation of the press.

“It is now time for the government to have the courage of its convictions,” she said, adding: “The public must be able to scrutinize the proposals. And Parliament — to whom Lord Justice Leveson trusted a key role in setting up the new system — must be able to decide.”

Cómo se desarrolló el Linux de las netbooks educativas






La elección de un sistema operativo para una computadora es una situación que, en situaciones cotidianas al ingresar a una tienda de venta de artículos electrónicos, está marcada por la presencia de la plataforma Windows de Microsoft. Nada de esto impide que los usuarios puedan optar por software libre, sin costo alguno al momento de realizar la descarga e instalación, con propuestas como Ubuntu, Fedora o Mint , por mencionar sólo algunas de las alternativas disponibles en Internet.


Esto mismo ocurrió con el plan Conectar Igualdad, que busca desarrollar su propia plataforma basada en GNU-Linux adaptada a las necesidades de la comunidad educativa, tanto para los docentes como para los alumnos.






La inciativa comenzó a tomar forma en 2010, cuando Javier Castrillo comenzó a trabajar en Conectar Igualdad, el programa del gobierno nacional que distribuye computadoras portátiles para alumnos y docentes de escuelas públicas. Desde aquel momento, con el antecedente de haber coordinado la implementación de estas iniciativas en el ambiente educativo, impulsó con su equipo el desarrollo de Huayra, el sistema operativo libre basado en GNU-Linux de las netbooks escolares.


“Debido al porte de este programa era necesaria una plataforma estable, libre, un estándar y sobre todo con soberanía tecnológica, para no depender de ninguna corporación. Con nuestro sistema nos aseguramos que va a ser constante en el tiempo, que va a ser gratuito para todos aquellos que lo quieran descargar y, por sobre todas las cosas, libre. Todo el código está publicado a disposición para que cualquiera que tenga los conocimientos lo pueda auditar y modificar”, asegura Javier Castrillo, coordinador del Proyecto Huayra.


En una entrevista exclusiva con LA NACIÓN , Javier Castrillo habla sobre la plataforma, sus características y los prejuicios que aún existen sobre el software libre.


¿Qué es Huayra?


Es el sistema operativo libre que las netbooks del Programa Conectar Igualdad van a traer instaladas a partir de este año. Además cualquier persona puede descargarlo en su máquina desde huayra.conectarigualdad.gob.ar


Está basado en Debian GNU/Linux, es seguro, ágil y con un desarrollo realizado en la Argentina, teniendo en cuenta las necesidades tanto de estudiantes como de docentes, y manteniendo nuestra identidad nacional.


¿En qué instancia se encuentra el desarrollo?


Está en fase Beta pero ya se puede bajar y utilizar.


Un mito presente en este tipo de plataformas es que muchas personas creen que no hay virus porque no se conoce mucho. Esto no es verdad, no hay virus porque el sistema no admite virus porque, como dije, está todo a la vista. Los servidores de la bases de datos de los bancos, las grandes bases de datos importantes son de código libre, Google es libre, por ejemplo.


¿Por qué pensaron que era necesario desarrollar un sistema operativo basado en software libre?


Porque se estaban dejando tres millones y medio de máquinas en manos de una corporación, que tiene intereses económicos y sus tiempos. Asimismo, por ejemplo, si queríamos hacer un procesador de texto para las comunidades aborígenes no podíamos hacerlo porque no es posible traducir el Word o si necesitábamos adaptar la placa de red, según el tipo de servicio de determinada zona también teníamos inconvenientes. Tener un software de una empresa es como comprarte un auto y tener el capó soldado.


¿Cuáles son las ventajas que presenta utilizar Huayra frente a Windows?


Es libre y puede ser utilizado por cualquier persona de la comunidad; es gratuito, y ofrece la libertad de poder administrar ese código y hacer las reformas que queremos. Uno de los problemas que veíamos era que los profesores traían un programa para compartir con los chicos y ponían el pendrive en cada computadora y lo bajaban, sin darse cuenta que podían utilizar la red de la escuela. Lo que sucede es que configurar una red no es algo trivial. Huayra, en cambio, autoconfigura la red entonces el profesor deja el programa directamente en una carpeta especial que comparte y los alumnos entran allí para utilizar el programa.


¿En qué se benefician los alumnos al utilizar Huayra?


Que el Estado les brinde su propio sistema operativo libre es un beneficio implícito es más seguro y mucho más rápido. Además, está pensado para que corra en las máquinas más livianas y también funciona bien en las máquinas más viejas.


Otra gran ventaja para los chicos es que tienen una herramienta que sale de la propia escuela, con las necesidades y el aporte de su institución. Hay cientos de aplicaciones del equipo de Huayra y aportadas por las comunidades escolares. En total son casi 30.000 piezas de software.


¿La interfaz es similar a la de Windows o los usuarios verán muchos cambios?


Es similar y además encontrarán programas que no tenían en Windows porque son muy caros. En Huayra, por ejemplo, hay un software para hacer animaciones en 3D que si tuviéramos que comprarlo saldría muy caro. También hay editores de fotos similares a Photoshop.


El procesador de textos de Huayra permite guardarlo en un formato de Word. En el pasado había grandes problemas de compatibilidad entre el software libre y el licenciado pero ahora todo ha evolucionado y ya no existen esos inconvenientes.


Las netbooks de Conectar Igualdad son de diez fabricantes distintos, y tuvimos que trabajar bastante para el desarrollo del sistema operativo, cuenta Javier Castrillo, responsable del proyecto Huayra


Todavía nos falta un buen programa de Autocad 3D, pero tenemos Autocad en 2D. Pero tenemos son muchas herramientas de programación y de robótica incluidas dentro de Hayra.


¿Cómo se realizará la capacitación?


Las netbooks de nuestro programa, a partir de 2012, incluyen TV Digital abierta y allí incluye un montón de tutoriales y paso a paso para poder aprender a utilizarla.


Por otro lado, todas las instancias de capacitación que tiene Educar y el Ministerio de Educación van a tener cursos de Huayra tanto para alumnos como para docentes. Y ya se han formado comunidades de Huayra en Facebook y en Twitter que hacen su propia formación y su aporte a la comunidad.


¿Qué obstáculos tuvieron que sortear?


La principal fue la compatibilidad de hardware. Las netbooks de Conectar Igualdad son de diez fabricantes distintos y tuvimos que trabajar bastante para hacer funcionar nuestro sistema en todos los equipos. Después debimos luchar con los prejuicios que difunden los propios monopolios, que dicen que Linux es difícil, por ejemplo.


Pero ahora estamos muy entusiasmados porque las pruebas están saliendo bien y estamos dentro de los tiempos previstos.


¿Cuáles son los principales proyectos?


La primera etapa de Huayra es que funcione bien en todas las netbooks y en eso estamos abocados. Luego estamos pensando en que funcione en tablets y celulares.


También queremos trabajar para que la TV digital no sirva sólo para ver canales sino que podamos interactuar y brindarle, a través de ella, información útil para el ciudadano.


Y queremos fomentar el desarrollo para que los chicos programen, dándoles herramientas para que puedan programar aunque no sepan hacerlo, para que puedan, por ejemplo, hacer sus propios juegos con las características de su región, de su lenguaje, sus costumbres y que lo compartan con la comunidad.


El software libre en Conectar Igualdad


Huayra toma su nombre del vocablo quechua que significa viento, una analogía que los responsables del proyecto buscan reflejar con la filosofía del proyecto, relacionada con la independencia tecnológica y la libertad que ofrece el software libre. “Es una práctica habitual dentro de la comunidad para que cada programa esté ser representado por un animal. Linux eligió el pingüino, nosotros una vaca”, explica Javier Castrillo.


El equipo de trabajo de Huayra consta de 13 personas, divididos en tres áreas: Desarrollo (programadores), Diseño (artistas, historiadores del arte, diseñadores gráficos) y Sistematización (Sociólogos y estadísticos).


Además de Huayra existe la iniciativa de la comunidad de software libre Tuquito, con sendas versiones para las computadoras de las iniciativas OLPC y Conectar Igualdad .

Woods wins at Torrey Pines for 8th time


SAN DIEGO (AP) — Tiger Woods was so good for so long at Torrey Pines that it didn't matter how bad it looked at the end.


In a finish that was fitting for such a long and exasperating week, Woods built an eight-shot lead with five holes to play on Monday until he lost patience with the slow play and started losing shots that only determined the margin of victory.


Despite two bogeys and a double bogey in the final hour, he closed with an even-par 72 for a four-shot victory in the Farmers Insurance Open.


"I'm excited the way I played all week," Woods said. "I hit the ball well — pretty much did everything well and built myself a nice little cushion. I had some mistakes at the end, but all my good play before that allowed me to afford those mistakes."


He won for the 75th time in his PGA Tour career, seven behind the record held by Sam Snead.


Woods won this tournament for the seventh time, and he set a PGA Tour record by winning at Torrey Pines for the eighth time, including his 2008 U.S. Open. Woods also has won seven times at Bay Hill and at Firestone.


Torrey Pines is a public course that he has turned into his private domain.


"I don't know if anybody would have beaten him this week," said Nick Watney, who got within five shots of Woods when the tournament was still undecided until making three bogeys on his next five holes. "He's definitely on his game."


It was the 23rd time Woods has won by at least four shots on the PGA Tour. Defending champion Brandt Snedeker (69) and Josh Teater (69) tied for the second. Watney had a 71 and tied for fourth with Jimmy Walker.


It was a strong statement for Woods, who was coming off a missed cut last week in Abu Dhabi. This was the second time in his career that Woods won in his next tournament after missing the cut, but this was the first time it happened the following week.


Abu Dhabi is now a distant memory. The question how is what kind of season is shaping up for Woods.


"I think he wanted to send a message," said Hunter Mahan, who shares a swing coach with Woods. "I think deep down he did. You play some games to try to motivate yourself. There's been so much talk about Rory (McIlroy). Rory is now with Nike. That would be my guess."


The last time Woods won at Torrey Pines also was on a Monday, when he beat Rocco Mediate in a playoff to capture the U.S. Open for his 14th major.


Of all his wins on this course along the Pacific, this might have been the most peculiar.


Thick fog cost the tournament an entire day of golf on Saturday, forcing the first Monday finish in tournament history. Woods effectively won the tournament during his 25 holes on Sunday, when he turned a two-shot lead into a six-shot margin with only 11 holes to play. CBS Sports wanted to televise the final day in late afternoon on the East Coast, but it still went long because of the pace of play.


It took Woods about 3 hours, 45 minutes to finish his 11 holes on Monday. His 19-hole win over Mediate lasted 4½ hours.


As much as Woods got off to a good start, equal attention was given to slow play, an increasing problem on the PGA Tour.


"It got a little ugly toward the end," Woods said. "I started losing patience a little bit with the slow play. I lost my concentration a little bit."


He made bogey from the bunker on No. 14. He hooked a tee shot off the eucalyptus trees and into a patch of ice plant on the 15th, leading to double bogey. After another long wait on the 17th tee, he popped up his tee shot and made another bogey. With a four-shot lead on the 18th — Kyle Stanley blew a three-shot lead a year ago — he hit wedge safely behind the hole for a two-putt par.


Woods finished on 14-under 274 for his 14th win in California, and 11th in San Diego County.


"I think a win always makes it special, especially the way I played," Woods said. "To have not won would have been something else because I really played well. Playing the way I did for most of this tournament, until the very end, the last five holes, I felt like I should have won this tournament. I put myself in a position where I had a big enough lead, and that's basically how I felt like I played this week.


"I know I can do that, and it was nice to be able to do it."


Like so many of his big wins, the only drama was for second place.


Brad Fritsch, the rookie from Canada, birdied his last two holes for a 75. That put him into a tie for ninth, however, making him eligible for the Phoenix Open next week. Fritsch had been entered in the Monday qualifier that he had to abandon when the Farmers Insurance Open lost Saturday to a fog delay.


Woods was so far ahead that he would have had to collapse for anyone to have a chance, and that never looked possible.


Even so, the red shirt seemed to put him on edge. It didn't help that as he settled over his tee shot on the par-5 ninth, he backed off when he heard a man behind the ropes take his picture.


Woods rarely hits the fairway after an encounter with a camera shutter, and this was no different — it went so far right that it landed on the other side of a fence enclosing a corporate hospitality area.


Woods took his free drop, punched out below the trees into the fairway and then showed more irritation when his wedge nicked the flag after one hop and spun down the slope 30 feet away instead of stopping next to the hole.


He didn't show much reaction on perhaps his most memorable shot of the day — with his legs near the edge of a bunker some 75 feet to the left of the 11th green, he blasted out to the top shelf and watched the ball take dead aim until it stopped a foot short. A two-putt birdie on the 13th gave him an eight-shot lead, and then it was only a matter of time — a lot of time — until the trophy presentation.


Before anyone projects a monster year for Woods based on one week, especially when that week is at Torrey Pines, remember that no one else in golf — not even McIlroy — is the subject of more snap judgments.


Woods, however, likes the direction he is headed, especially with his short game.


"I'm excited about this year. I'm excited about what I'm doing with Sean (Foley) and some of the things that I've built," he said. "This is a nice way to start the year."


Woods is not likely to return to golf until the Match Play Championship next month.
