Disruptions: Disruptions: 3-D Printing Is on the Fast Track

Will the future be printed in 3-D?

At first glance, looking at past predictions about the future of technology, prognosticators got a whole lot wrong. The Web is a garbage dump of inaccurate guesses about the year 2000, 2010 and beyond. Flying cars, robotic maids and jet packs still are nowhere near a reality.

Yet the prediction that 3-D printers will become a part of our daily lives is happening much sooner than anyone anticipated. These printers can produce objects, even rather intricate ones, by printing thin layer after layer of plastic, metal, ceramics or other materials. And the products they make can be highly customized.

Last week, President Obama cited this nascent technology during his State of the Union address — as if everyone already knew what the technology was.

He expressed hope that it was a way to rejuvenate American manufacturing. “A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the 3-D printing that has the potential to revolutionize the way we make almost everything,” Mr. Obama said. He has pushed new technologies before, like solar and wind power, as remedies for our nation’s problems, and those attempts have only revived the debate about the limitations of government industrial policy.

But this one shows more promise. The question is, can the United States get a foothold in manufacturing one 3-D printer at a time?

Hod Lipson, an associate professor and the director of the Creative Machines Lab at Cornell, said “3-D printing is worming its way into almost every industry, from entertainment, to food, to bio- and medical-applications.”

It won’t necessarily directly create manufacturing jobs, except perhaps for the printers themselves. Dr. Lipson, the co-author of “Fabricated: The New World of 3D Printing,” said that the technology “is not going to simply replace existing manufacturing anytime soon.” But he said he believed that it would give rise to new businesses. “The bigger opportunity in the U.S. is that it opens and creates new business models that are based on this idea of customization.”

In addition to the lab that the president mentioned, a federally financed manufacturing innovation institute in Youngstown, Ohio, schools are embracing the technology. The University of Virginia has been working to introduce 3-D printers into some programs from kindergarten through 12th grade in Charlottesville to prepare students for a new future in manufacturing.

“We have 3-D printers in classrooms, and in one example, we’re teaching kids how to design and print catapults that they then analyze for efficiency,” said Glen L. Bull, professor and co-director of the Center for Technology and Teacher Education. “We believe that every school in America could have a 3-D printer in the classroom in the next few years.”

The education system may want to speed things up. The time between predictions for 3-D printers and the reality of what they can accomplish is compressing rapidly.

For example, in 2010, researchers at the University of Southern California said that another decade would pass before we could build a home using a 3-D printer. Yet last week, Softkill Design, a London architecture collective, announced that it planned to make the first such home — which it will assemble in a single day — later this year. The home isn’t that pretty, and will look more like a calcified spider web than a cozy house, but it will show it can be done. The price of 3-D printers has also dropped sharply over the last two years, with machines that once cost $20,000, now at $1,000 or less. That’s partly because Chinese companies are driving down prices. Yes, China sees the opportunity in these things, even though the technology may undermine some of its manufacturing advantages.

“When it costs you the same amount of manufacturing effort to make advanced robotic parts as it does to manufacture a paperweight, that really changes things in a profound way,” Dr. Lipson said.

This leaves us with one more question about the future: When will these 3-D printers be able to make us flying cars, robotic maids and jet packs?

IHT Rendezvous: Should Common Plastics Be Labeled Toxic?

THE HAGUE — Hoping to reduce one of the most ubiquitous forms of waste, a global group of scientists is proposing that certain types of plastic be labeled hazardous.

The group, led by two California scientists, wrote in this week’s issue of the scientific journal Nature:

We believe that if countries classified the most harmful plastics as hazardous, their environmental agencies would have the power to restore affected habitats and prevent more dangerous debris from accumulating.

While 280 million tons of plastic were produced globally last year, less than half of that plastic has ended up in landfills or was recycled, according to the scientists’ data. Some of the unaccounted for 150 million tons of plastic is still in use, but much of it litters roadsides, cities, forests, deserts, beaches and oceans. (Just think of the great floating garbage patches at sea).

Unlike other forms of solid waste, such as uneaten food, scrap metal or last year’s clothes, plastics take an especially long time to break down. And when they finally do, they create hazardous, even toxic particles that can harm wildlife, ecosystems and humans.

For now, the group — led by Chelsea M. Rochman of the School of Veterinary Medicine at the University of California, Davis, and Mark Anthony Browne at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California — is calling for the reclassification of plastics that are particularly difficult to recycle and that are most toxic when degrading: PVC, polystyrene, polyurethane and polycarbonate.

The scientists say these types of plastics — used in construction, food containers, electronics and furniture — make up an estimated 30 percent of all plastics produced.

Join our sustainability conversation. Does it make sense to re-classify common plastics as hazardous, or are there better ways to reduce the amount of plastics we throw out?

No. 2 Duke falls to Maryland 83-81

COLLEGE PARK, Md. (AP) — As the final horn sounded and Maryland fans rushed the court to celebrate a rare victory over its bitter rival, weary Duke had just enough energy left to escape the mayhem for the safety of its locker room.

Seth Allen broke a tie by making two free throws with 2.8 seconds left, and the Terrapins stunned the second-ranked Blue Devils 83-81 Saturday night to end a six-game skid in the series.

Coming off a five-day break, Maryland notched its most significant win of the season at the expense of a tired Duke playing its fourth game in 10 days.

The Blue Devils were worn out, and it showed.

Duke was outrebounded 40-20, never led in the second half and got only four points and three rebounds from 6-foot-10 senior center Mason Plumlee.

"This has been an exhausting schedule for our team," coach Mike Krzyzewski said. "We're playing on fumes and I think you could tell that with Mason. I thought he looked exhausted the whole game. He's been great. Obviously not good tonight."

The Terrapins (18-7, 6-6 Atlantic Coast Conference) did not trail after halftime but never could pull away.

Duke (22-3, 9-3) was down by 10 with 3:39 left but pulled even when Rasheed Sulaimon made three foul shots with 16.7 seconds to go. Quinn Cook then fouled Allen as the freshman guard drove through the lane, and Allen made both shots.

After a Duke timeout, Cook's desperation 30-footer bounced off the back rim. Chaos ensued as the fans immediately rushed the court.

"I thought it was in when I got it off," Cook said of his final attempt.

Alex Len had 19 points and nine rebounds for Maryland, and Allen scored 16. The Terrapins had lost 12 of 13 against Duke, including a 20-point embarrassment last month.

"I told our players before the game, there's a lot of pride in Maryland basketball," coach Mark Turgeon said. "There's also a lot of passion about Maryland basketball. We talked about playing with those two things for us and for our fans. Our fans were just tremendous."

From the end of the Star Spangled Banner to the final buzzer, the crowd never stopped shouting for the Terps, who rewarded their fans with a memorable victory in a rivalry that appears destined to end when Maryland leaves for the Big Ten in 2014.

"I have a great deal of respect for Maryland," Krzyzewski said. "If it was such a rivalry they'd still be in the ACC. Obviously they don't think it's that important or else they wouldn't be in the Big Ten."

Oh, but it's very important to Maryland and its coach.

"This win was for my family and the fans," Turgeon said. "I know what this win means for our fan base, and I really wanted to beat Duke."

The Blue Devils had their six-game winning streak end. Seth Curry scored 25 and Cook added 18. But Plumlee was completely outplayed by the 7-1 Len, who went 6 for 8 from the field and 7 for 8 at the foul line.

"There's so much pressure for Mason to play outstanding," Krzyzewski said. "That wears on you as the season goes on. He just didn't look fresh tonight."

Said Plumlee: "I didn't show up to play today and I let my teammates down. It's all on me."

Maryland committed a whopping 26 turnovers, eight by Allen. The Terrapins shot an impressive 60 percent from the floor and finished with a 40-20 rebounding advantage.

Maryland played without reserve guard Pe'Shon Howard, who was suspended for violating team rules. Despite being demoted from his starting role last month, Howard still leads the Terrapins in assists.

Maryland led 66-63 before Allen scored on a drive. Dez Wells then stole the ball from Cook and went in for a dunk for a seven-point lead with 5:20 left. After the Blue Devils closed to 71-63, James Padgett made a layup for Maryland and Wells made two foul shots for a 10-point cushion.

The crowd increased its volume with every subsequent basket by the Terrapins, whose previous win over Duke came in March 2010, when Greivis Vasquez celebrated Senior Night with a 20-point performance.

In this one, it was 80-72 before Curry made two straight 3-pointers to bring Duke to 80-78 with just under a minute left. After Wells was called for a charge, Curry had a 15-footer bounce in and out of the basket.

It was that kind of night for the Blue Devils.

This score was 39 all before Allen hit a 3-pointer to spark a 10-2 run that included five points from freshman Shaquille Cleare. It was 53-43 before Curry bagged a 3-pointer, Alex Murphy made a layup and Curry drove the lane following Maryland's third turnover in a 60-second span.

That cut the gap to three points, and seconds after a 3-pointer by Cook got the Blue Devils to 55-53.

After the Terrapins went up by six, they committed turnovers on three straight possessions. That enabled Duke to close to 59-57 on a dunk by Murphy, but four straight free throws by Len gave Maryland a 64-59 advantage with 7:20 remaining.

The first half featured two ties, 10 lead changes and ended with the Terrapins up 35-34. Curry (14 points) was one of only four Duke players to score before halftime.

Cuomo Bucks Tide With Bill to Lift Abortion Limits

ALBANY — Bucking a trend in which states have been seeking to restrict abortion, Gov. Andrew M. Cuomo is putting the finishing touches on legislation that would guarantee women in New York the right to late-term abortions when their health is in danger or the fetus is not viable.

Mr. Cuomo, seeking to deliver on a promise he made in his recent State of the State address, would rewrite a law that currently allows abortions after 24 weeks of pregnancy only if the pregnant woman’s life is at risk. The law is not enforced, because it is superseded by federal court rulings that allow late-term abortions to protect a woman’s health, even if her life is not in jeopardy. But abortion rights advocates say the existence of the more restrictive state law has a chilling effect on some doctors and prompts some women to leave the state for late-term abortions.

Mr. Cuomo’s proposal, which has not yet been made public, would also clarify that licensed health care practitioners, and not only physicians, can perform abortions. It would remove abortion from the state’s penal law and regulate it through the state’s public health law.

Abortion rights advocates have welcomed Mr. Cuomo’s plan, which he outlined in general terms as part of a broader package of women’s rights initiatives in his State of the State address in January. But the Roman Catholic Church and anti-abortion groups are dismayed; opponents have labeled the legislation the Abortion Expansion Act.

The prospects for Mr. Cuomo’s effort are uncertain. The State Assembly is controlled by Democrats who support abortion rights; the Senate is more difficult to predict because this year it is controlled by a coalition of Republicans who have tended to oppose new abortion rights laws and breakaway Democrats who support abortion rights.

New York legalized abortion in 1970, three years before it was legalized nationally by the Supreme Court in Roe v. Wade. Mr. Cuomo’s proposal would update the state law so that it could stand alone if the broader federal standard set by Roe were to be undone.

“Why are we doing this? The Supreme Court could change,” said a senior Cuomo administration official, who spoke on the condition of anonymity because the governor had not formally introduced his proposal.

But opponents of abortion rights, already upset at the high rate of abortions in New York State, worry that rewriting the abortion law would encourage an even greater number of abortions. For example, they suggest that the provision to allow abortions late in a woman’s pregnancy for health reasons could be used as a loophole to allow unchecked late-term abortions.

“I am hard pressed to think of a piece of legislation that is less needed or more harmful than this one,” the archbishop of New York, Cardinal Timothy M. Dolan, wrote in a letter to Mr. Cuomo last month. Referring to Albany lawmakers in a subsequent column, he added, “It’s as though, in their minds, our state motto, ‘Excelsior’ (‘Ever Upward’), applies to the abortion rate.”

National abortion rights groups have sought for years to persuade state legislatures to adopt laws guaranteeing abortion rights as a backup to Roe. But they have had limited success: Only seven states have such measures in place, including California, Connecticut and Maryland; the most recent state to adopt such a law is Hawaii, which did so in 2006.

“Pretty much all of the energy, all of the momentum, has been to restrict abortion, which makes what could potentially happen in New York so interesting,” said Elizabeth Nash, state issues manager at the Guttmacher Institute, a research group that supports abortion rights. “There’s no other state that’s even contemplating this right now.”

In most statehouses, the push by lawmakers has been in the opposite direction. The past two years has seen more provisions adopted at the state level to restrict abortion rights than in any two-year period in decades, according to the Guttmacher Institute; last year, 19 states adopted 43 new provisions restricting abortion access, while not a single significant measure was adopted to expand access to abortion or to comprehensive sex education.

“It’s an extraordinary moment in terms of the degree to which there is government interference in a woman’s ability to make these basic health care decisions,” said Andrea Miller, the president of NARAL Pro-Choice New York. “For New York to be able to send a signal, a hopeful sign, a sense of the turning of the tide, we think is really important.”

Abortion rights advocates say that even though the Roe decision supersedes state law, some doctors are hesitant to perform late-term abortions when a woman’s health is at risk because the criminal statutes remain on the books.

“Doctors and hospitals shouldn’t be reading criminal laws to determine what types of health services they can offer and provide to their patients,” said M. Tracey Brooks, the president of Family Planning Advocates of New York State.

For Mr. Cuomo, the debate over passing a new abortion law presents an opportunity to appeal to women as well as to liberals, who have sought action in Albany without success since Eliot Spitzer made a similar proposal when he was governor. But it also poses a challenge to the coalition of Republicans and a few Democrats that controls the State Senate, the chamber that has in the past stood as the primary obstacle to passing abortion legislation in the capital.

The governor has said that his Reproductive Health Act would be one plank of a 10-part Women’s Equality Act that also would include equal pay and anti-discrimination provisions. Conservative groups, still stinging from the willingness of Republican lawmakers to go along with Mr. Cuomo’s push to legalize same-sex marriage in 2011, are mobilizing against the proposal. Seven thousand New Yorkers who oppose the measure have sent messages to Mr. Cuomo and legislators via the Web site of the New York State Catholic Conference.

A number of anti-abortion groups have also formed a coalition called New Yorkers for Life, which is seeking to rally opposition to the governor’s proposal using social media.

“If you ask anyone on the street, ‘Is there enough abortion in New York?’ no one in their right mind would say we need more abortion,” said the Rev. Jason J. McGuire, the executive director of New Yorkers for Constitutional Freedoms, which is part of the coalition.

Members of both parties say that the issue of reproductive rights was a significant one in November’s legislative elections. Democrats, who were bolstered by an independent expenditure campaign by NARAL, credit their victories in several key Senate races in part to their pledge to fight for legislation similar to what Mr. Cuomo is planning to propose.

Republicans, who make up most of the coalition that controls the Senate, have generally opposed new abortion rights measures. Speaking with reporters recently, the leader of the Republicans, Dean G. Skelos of Long Island, strenuously objected to rewriting the state’s abortion laws, especially in a manner similar to what the governor is seeking.

“You could have an abortion up until the day the child would be born, and I think that’s just wrong,” Mr. Skelos said. He suggested that the entire debate was unnecessary, noting that abortion is legal in New York State and saying that is “not going to be changed.”

The Senate Democratic leader, Andrea Stewart-Cousins of Yonkers, who is the sponsor of a bill that is similar to the legislation the governor is drafting, said she was optimistic that an abortion measure would reach the Senate floor this year.

“New York State’s abortion laws were passed in 1970 in a bipartisan fashion,” she said. “It would be a sad commentary that over 40 years later we could not manage to do the same thing.”

A First Step on Continent for Google on Use of Content

PARIS — Publishers in France say they have struck an innovative agreement with Google on the use of their content online. Their counterparts elsewhere in Europe, however, say the French gave in too easily to the Internet giant.

The deal was signed this month by President François Hollande of France and Eric E. Schmidt, the executive chairman of Google, who called it a breakthrough in the tense relationship between publishers and Google, and as a possible model for other countries to follow.

Under the deal, Google agreed to set up a fund, worth €60 million, or $80 million, over three years, to help publishers develop their digital units. The two sides also pledged to deepen business ties, using Google’s online tools, in an effort to generate more online revenue for the publishers, who have struggled to counteract dwindling print revenue.

But the French group, representing newspaper and magazine publishers with an online presence, as well as a variety of other news-oriented Web sites, yielded on its most important demand: that Google and other search engines and “aggregators” of news should start paying for links to their content.

Google, which insists that its links provide a service to publishers by directing traffic to their sites, had fiercely resisted any change in the principle of free linking.

The agreement dismayed members of the European Publishers Council, a lobbying group in Brussels, which has been pushing for a fundamental change in the relationship between publishers and Google. The group criticized the French publishers for breaking ranks and striking a separate business agreement that has no statutory standing.

The deal “does not address the continuing problem of unauthorized reuse and monetization of content, and so does not provide the online press with the financial certainty or mechanisms for legal redress which it needs to build sustainable business models and ensure its continued investment in high-quality content,” Angela Mills Wade, executive director of the publishers council, said in a statement.

German publishers were also scornful, with Anja Pasquay, a spokeswoman for the German Newspaper Publishers’ Association, saying: “Obviously the French position isn’t one that we would favor. This is not the solution for Germany.”

Germany has been in the forefront of the push to get Google to share with online news publishers some of the billions of euros that the company earns from the sale of advertising. A proposed law, endorsed by the government of Chancellor Angela Merkel and working its way through the federal legislature, would grant a new form of copyright to digital publishers. If enacted, it could allow publishers to charge search engines or aggregators for displaying even snippets of news articles alongside links to other Web sites.

Mr. Hollande had vowed to introduce similar legislation this winter if Google and the publishers did not come to terms. It appears that Google, which had threatened to stop indexing French Web sites’ content if it had to pay for links, has sidelined the threat of legislation, at least for now; the agreement will be reviewed after three years, Mr. Hollande has said.

Under the deal, Google says it will help the publishers use several of its digital advertising services, including AdSense, AdMob and Ad Exchange, more effectively.

Publishers are already free to use these services, and it was not immediately clear how they would be able to generate more revenue from them; this part of the accord remains confidential, both sides say, because they are still negotiating the fine print.

“This agreement can help accelerate the move toward greater advertising revenues in the digital world,” said Marc Schwartz of Mazars, a consulting firm, who is serving as an independent mediator in the talks. “I’m not saying we have done everything, but it’s a first step in the right direction.”

More has been said about the planned innovation fund. Publishers will submit proposals to the fund, which will select ideas to finance and develop, with the involvement of Google engineers.

“The idea is that it would inject innovation into the sector in France,” said Simon Morrison, copyright policy manager at Google.

US teen Mikaela Shiffrin wins world slalom title

SCHLADMING, Austria (AP) — American teenager Mikaela Shiffrin became the youngest women's slalom world champion in 39 years on Saturday.

At the age of 17 years, 340 days, Shiffrin beat all of her more experienced rivals to earn the U.S. team its fourth gold and fifth medal overall at the worlds, more than any other nation.

"It's such a crazy day," Shiffrin said. "It's so emotional ... I don't know yet, I can't feel yet. It's amazing."

The 17-year-old Shiffrin was third after the opening run but finished in a combined time of 1 minute, 39.85 seconds to beat Michaela Kirchgasser of Austria by 0.22 and Frida Hansdotter of Sweden by 0.26.

After the race in front of a crowd of 30,000 had ended, Shiffrin looked around in disbelief before hugging second-place Kirchgasser several times. Shiffrin's parents Jeff and Eileen embraced each other at the stands.

"I keep saying it, I keep thinking it. It doesn't make sense. It's just me," Shiffrin said when asked how it felt to be world champion.

In the first run, Shiffrin said she didn't feel quite right.

"I just tried to find my legs. They popped up out of nowhere," she said. "I was in the starting gate and I was like, 'Oh, there they are, I can go now!'"

After finish in first, Shiffrin thought, "I hope it holds. I was thinking so many things and I just can't even remember it. It's one of those things where everything is a blur and that's how you know it was good."

Shiffrin said she was inspired by teammate Ted Ligety, who won the men's super-G, super-combined and GS titles.

"Oh yeah! For sure," she said. "I think everyone was. That was amazing."

Julia Mancuso won the United States' first medal by taking bronze in the event-opening super-G.

Shiffrin is the youngest women's world champion in any discipline since fellow American Diann Roffe-Steinrotter, who was 21 days younger when she won the giant slalom title in 1985.

The only slalom world champions younger than Shiffrin were Hanni Wenzel of Liechtenstein in 1974 and Esme Mackinnon of Britain in 1931.

Shiffrin had already had a breakthrough year, winning three World Cup slaloms this season to lead the discipline standings.

By winning in Zagreb, Croatia, in early January, she became the first American woman to win two World Cup races before the age of 18. In Flachau, Austria, she added a third victory to match a record set by legend Annemarie Moser-Proell, was in 1971 at exactly the same age of 17 years, 308 days when she won her third of 62 races.

Hansdotter led the race after the opening run but could not match Shiffrin's pace in the final. The Swede had finished runner-up to Shiffrin in each of the American's World Cup wins.

"I am super happy," Hansdotter said. I had two good runs and now I have a medal. I wasn't nervous. I have to be happy because I have got a medal."

Kirchgasser, who was part of the Austrian team that won gold in the mixed team event Tuesday, earned her first individual medal at a major championship.

"It's just great. I thought, all or nothing," said Kirchgasser, who just missed the podium in fourth during the super-combined last week. "I didn't want to end up in fourth again."

Olympic slalom champion Maria Hoefl-Riesch of Germany, who won the super-combined world title last week, had 0.20 to make up in the final run but straddled a gate and failed to finish.

The fans cheered loudly for Schild on her return less than two months after picking up what initially appeared to be a season-ending knee injury in December. The World Cup champion hadn't raced since the slalom 83 days ago in Aspen, Colo., and placed ninth, 1.58 behind Shiffrin.

The men's slalom Sunday is the final event of the world championships.

Livestrong Tattoos as Reminder of Personal Connections, Not Tarnished Brand

As Jax Mariash went under the tattoo needle to have “Livestrong” emblazoned on her wrist in bold black letters, she did not think about Lance Armstrong or doping allegations, but rather the 10 people affected by cancer she wanted to commemorate in ink. It was Jan. 22, 2010, exactly a year since the disease had taken the life of her stepfather. After years of wearing yellow Livestrong wristbands, she wanted something permanent.

A lifelong runner, Mariash got the tattoo to mark her 10-10-10 goal to run the Chicago Marathon on Oct. 10, 2010, and fund-raising efforts for Livestrong. Less than three years later, antidoping officials laid out their case against Armstrong — a lengthy account of his practice of doping and bullying. He did not contest the charges and was barred for life from competing in Olympic sports.

“It’s heartbreaking,” Mariash, of Wilson, Wyo., said of the antidoping officials’ report, released in October, and Armstrong’s subsequent confession to Oprah Winfrey. “When I look at the tattoo now, I just think of living strong, and it’s more connected to the cancer fight and optimal health than Lance.”

Mariash is among those dealing with the fallout from Armstrong’s descent. She is not alone in having Livestrong permanently emblazoned on her skin.

Now the tattoos are a complicated, internationally recognized symbol of both an epic crusade against cancer and a cyclist who stood defiant in the face of accusations for years but ultimately admitted to lying.

The Internet abounds with epidermal reminders of the power of the Armstrong and Livestrong brands: the iconic yellow bracelet permanently wrapped around a wrist; block letters stretching along a rib cage; a heart on a foot bearing the word Livestrong; a mural on a back depicting Armstrong with the years of his now-stripped seven Tour de France victories and the phrase “ride with pride.”

While history has provided numerous examples of ill-fated tattoos to commemorate lovers, sports teams, gang membership and bands that break up, the Livestrong image is a complex one, said Michael Atkinson, a sociologist at the University of Toronto who has studied tattoos.

“People often regret the pop culture tattoos, the mass commodified tattoos,” said Atkinson, who has a Guns N’ Roses tattoo as a marker of his younger days. “A lot of people can’t divorce the movement from Lance Armstrong, and the Livestrong movement is a social movement. It’s very real and visceral and embodied in narrative survivorship. But we’re still not at a place where we look at a tattoo on the body and say that it’s a meaningful thing to someone.”

Geoff Livingston, a 40-year-old marketing professional in Washington, D.C., said that since Armstrong’s confession to Winfrey, he has received taunts on Twitter and inquiries at the gym regarding the yellow Livestrong armband tattoo that curls around his right bicep.

“People see it and go, ‘Wow,’ ” he said, “But I’m not going to get rid of it, and I’m not going to stop wearing short sleeves because of it. It’s about my family, not Lance Armstrong.”

Livingston got the tattoo in 2010 to commemorate his brother-in-law, who was told he had cancer and embarked on a fund-raising campaign for the charity. If he could raise $5,000, he agreed to get a tattoo. Within four days, the goal was exceeded, and Livingston went to a tattoo parlor to get his seventh tattoo.

“It’s actually grown in emotional significance for me,” Livingston said of the tattoo. “It brought me closer to my sister. It was a big statement of support.”

For Eddie Bonds, co-owner of Rabbit Bicycle in Hill City, S.D., getting a Livestrong tattoo was also a reflection of the growth of the sport of cycling. His wife, Joey, operates a tattoo parlor in front of their store, and in 2006 she designed a yellow Livestrong band that wraps around his right calf, topped off with a series of small cyclists.

“He kept breaking the Livestrong bands,” Joey Bonds said. “So it made more sense to tattoo it on him.”

“It’s about the cancer, not Lance,” Eddie Bonds said.

That was also the case for Jeremy Nienhouse, a 37-year old in Denver, Colo., who used a Livestrong tattoo to commemorate his own triumph over testicular cancer.

Given the diagnosis in 2004, Nienhouse had three rounds of chemotherapy, which ended on March 15, 2005, the date he had tattooed on his left arm the day after his five-year anniversary of being cancer free in 2010. It reads: “3-15-05” and “LIVESTRONG” on the image of a yellow band.

Nienhouse said he had heard about Livestrong and Armstrong’s own battle with the cancer around the time he learned he had cancer, which alerted him to the fact that even though he was young and healthy, he, too, could have cancer.

“On a personal level,” Nienhouse said, “he sounds like kind of a jerk. But if he hadn’t been in the public eye, I don’t know if I would have been diagnosed when I had been.”

Nienhouse said he had no plans to have the tattoo removed.

As for Mariash, she said she read every page of the antidoping officials’ report. She soon donated her Livestrong shirts, shorts and running gear. She watched Armstrong’s confession to Winfrey and wondered if his apology was an effort to reduce his ban from the sport or a genuine appeal to those who showed their support to him and now wear a visible sign of it.

“People called me ‘Miss Livestrong,’ ” Mariash said. “It was part of my identity.”

She also said she did not plan to have her tattoo removed.

“I wanted to show it’s forever,” she said. “Cancer isn’t something that just goes away from people. I wanted to show this is permanent and keep people remembering the fight.”

The Lede: Spectacular Video of Meteor Over Siberia

Video posted on YouTube Friday appeared to catch an explosion caused by a meteor streaking over the Russian city of Chelyabinsk.

Last Updated, 11:08 a.m. As our colleagues Ellen Barry and Andrew Kramer report, Russians recorded video of bright objects, apparently debris from a meteor, “streaking through the sky in western Siberia early on Friday, accompanied by a boom that damaged buildings across a vast area of territory.” Hundreds of injuries were reported, mainly from breaking glass.

Video recorded from the dashboard camera of a car in the Russian city of Chelyabinsk on Friday.

Video said to have been recorded on Friday in the Russian city of Chelyabinsk as a meteor passed low overhead. An explosion can be heard clearly at the 7-minute mark of the video.

The video clips, many recorded from cars on the dashboard cameras that are popular in Russia, quickly spread from social networks to Russian news sites. While it was not possible to confirm the authenticity of these clips, they track closely with witness accounts and each other.

Video uploaded to YouTube on Friday was said to have been recorded over the Russian city of Chelyabinsk (although the camera’s time stamp displays an earlier date).

Several clips showed a flaming object streaking through the sky and a burst of blinding light followed by a smoke trail. One, shot by a driver named Alexander Mezentsev, showed a bright light over a city street in Chelyabinsk, a city of 1 million about 900 miles east of Moscow.

One clip, recorded on a street in Chelyabinsk, appeared to capture the chaotic aftermath of the event, as glass shattered following the shock wave and people shouted and tried to make sense of what was happening.

A very loud explosion could be heard about 25 seconds into another video, apparently recorded on a phone in the same city by a blogger named Sergey Hametov.

Video said to have been recorded on Friday in Chelyabinsk appeared to capture a loud explosion.

“There was panic. People had no idea what was happening,” Mr. Hametov told The Associated Press. “We saw a big burst of light, then went outside to see what it was and we heard a really loud, thundering sound.”

Another video, shot from the window of a building, seemed to capture the long trail of smoke after the object passed through the sky.

Video posted on YouTube Friday appeared to show the trail of a meteorite fragment in the sky.

Several clips also showed what bloggers said was the damage caused by the sonic boom.

Some of the numerous videos that quickly emerged of the incident highlighted a distinctly Russian phenomenon: the dashboard cam. As the blogger Marina Galperina explained last year, they are commonplace in Russia partly because of the dangerous driving conditions that lead to so many accidents, and with an unreliable police force such cameras can provide valuable evidence following a crash.

The conditions of Russian roads are perilous, with insane gridlock in cities and gigantic ditches, endless swamps and severe wintry emptiness on the backroads and highways. Then there are large, lawless areas you don’t just ride into, the police with a penchant for extortion and deeply frustrated drivers who want to smash your face.

Psychopaths are abundant on Russian roads. You best not cut anyone off or undertake some other type of maneuver that might inconvenience the 200-pound, six-foot-five brawling children you see on YouTube hopping out of their SUVs with their dukes up. They will go ballistic in a snap, drive in front of you, brake suddenly, block you off, jump out and run towards your vehicle. Next thing you start getting punches in your face because your didn’t roll up your windows, or getting pulled out of the car and beaten because you didn’t lock the doors.

These fights happen all the time and you can’t really press charges. Point to your broken nose or smashed windows all you want. The Russian courts don’t like verbal claims. They do, however, like to send people to jail for battery and property destruction if there’s definite video proof.

Yankees razz Youkilis for Red Sox remarks

TAMPA, Fla. (AP) — Kevin Youkilis' new teammates were waiting to razz him when the third baseman walked into the New York Yankees clubhouse.

Youkilis made the back page of two New York newspapers Friday for telling reporters at the first day of spring training that "I'll always be a Red Sox."

"I was basically defining that, as a player, I'll be a Red Sox, and a White Sox, and a Yankee for life," Youkilis said Friday. "Three storied franchises. I'm excited to be part of this, and be with the Yankees. Trust me, there's no way that was meant to say my heart is in Boston or anything like that. My heart is here with the Yankees."

Youkilis took part in his first workout with the Yankees on Thursday after flying from California to Tampa.

"I think guys are having fun with it, joking around," Youkilis said.
