UK’s Prince Charles takes first “Tube” trip since 1986






LONDON (Reuters) – Four million Londoners cram onto the city’s Underground passenger railway nearly every day, but it is a rarer event for Prince Charles. He rode the British capital’s bustling commuter network on Wednesday for the first time since 1986.


The heir to the British throne and his wife Camilla took a one-stop journey from Farringdon to King’s Cross on the Metropolitan Line as part of celebrations to mark the 150th anniversary of a transport service affectionately known to Britons as the “Tube”.






The short journey was a rare enough event to cause some confusion at the prince’s press office, which initially said he had last ventured onto the Tube in 1979.


“This is just to let you know that it has come to our attention that The Prince of Wales has travelled on the London Underground more recently than 1979. In 1986 The Prince and Princess of Wales travelled by tube to Heathrow Airport to open Terminal 4,” a spokeswoman said in an email to media.


“We’re sorry that our previous information was incorrect. Our archives of Royal engagements prior to 1988 are not computerized and in this particular instance a search under ‘The Prince of Wales takes the Tube’ did not bring up an event which had been logged as the ‘official opening of Terminal 4′.”

Phys Ed: Helmets for Ski and Snowboard Safety

Phys Ed

Gretchen Reynolds on the science of fitness.

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.”

During Trial, New Details Emerge on DuPuy Hip





When Johnson & Johnson announced the appointment in 2011 of an executive to head the troubled orthopedics division whose badly flawed artificial hip had been recalled, the company billed the move as a fresh start.




But that same executive, it turns out, had supervised the implant’s introduction in the United States and had been told by a top company consultant three years before the device was recalled that it was faulty.


In addition, the executive also held a senior marketing position at a time when Johnson & Johnson decided not to tell officials outside the United States that American regulators had refused to allow sale of a version of the artificial hip in this country.


The details about the involvement of the executive, Andrew Ekdahl, with the all-metal hip implant emerged Wednesday in Los Angeles Superior Court during the trial of a patient lawsuit against the DePuy Orthopaedics division of Johnson & Johnson. More than 10,000 lawsuits have been filed against DePuy in connection with the device — the Articular Surface Replacement, or A.S.R. — and the Los Angeles case is the first to go to trial.


The information about the depth of Mr. Ekdahl’s involvement with the implant may raise questions about DePuy’s ability to put the A.S.R. episode behind it.


Asked in an e-mail why the company had promoted Mr. Ekdahl, a DePuy spokeswoman, Lorie Gawreluk, said the company “seeks the most accomplished and competent people for the job.”


On Wednesday, portions of Mr. Ekdahl’s videotaped testimony were shown to jurors in the Los Angeles case. Other top DePuy marketing executives who played roles in the A.S.R. development are expected to testify in coming days. Mr. Ekdahl, when pressed in the taped questioning on whether DePuy had recalled the A.S.R. because it was unsafe, repeatedly responded that the company had recalled it “because it did not meet the clinical standards we wanted in the marketplace.”


Before the device’s recall in mid-2010, Mr. Ekdahl and those executives all publicly asserted that the device was performing extremely well. But internal documents that have become public as a result of litigation conflict with such statements.


In late 2008, for example, a surgeon who served as one of DePuy’s top consultants told Mr. Ekdahl and two other DePuy marketing officials that he was concerned about the cup component of the A.S.R. and believed it should be “redesigned.” At the time, DePuy was aggressively promoting the device in the United States as a breakthrough and it was being implanted into thousands of patients.


“My thoughts would be that DePuy should at least de-emphasize the A.S.R. cup while the clinical results are studied,” that consultant, Dr. William Griffin, wrote.


A spokesman for Dr. Griffin said he was not available for comment.


The A.S.R., whose cup and ball components were both made of metal, was first sold by DePuy in 2003 outside the United States for use in an alternative hip replacement procedure called resurfacing. Two years later, DePuy started selling another version of the A.S.R. for use here in standard hip replacement that used the same cup component as the resurfacing device. Only the standard A.S.R. was sold in the United States; both versions were sold outside the country.


Before the device recall in mid-2010, about 93,000 patients worldwide received an A.S.R., about a third of them in this country. Internal DePuy projections estimate that it will fail in 40 percent of those patients within five years; a rate eight times higher than for many other hip devices.


Mr. Ekdahl testified via tape Wednesday that he had been placed in charge of the 2005 introduction of the standard version of the A.S.R. in this country. Within three years, he and other DePuy executives were receiving reports that the device was failing prematurely at higher than expected rates, apparently because of problems related to the cup’s design, documents disclosed during the trial indicate.


Along with other DePuy executives, he also participated in a meeting that resulted in a proposal to redesign the A.S.R. cup. But that plan was dropped, apparently because sales of the implant had not justified the expense, DePuy documents indicate.


In the face of growing complaints from surgeons about the A.S.R., DePuy officials maintained that the problems were related to how surgeons were implanting the cup, not from any design flaw. But in early 2009, a DePuy executive wrote to Mr. Ekdahl and other marketing officials that the early failures of the A.S.R. resurfacing device and the A.S.R. traditional implant, known as the XL, were most likely design-related.


“The issue seen with A.S.R. and XL today, over five years post-launch, are most likely linked to the inherent design of the product and that is something we should recognize,” that executive, Raphael Pascaud wrote in March 2009.


Last year, The New York Times reported that DePuy executives decided in 2009 to phase out the A.S.R. and sell existing inventories weeks after the Food and Drug Administration asked the company for more safety data about the implant.


The F.D.A. also told the company at that time that it was rejecting its efforts to sell the resurfacing version of the device in the United States because of concerns about “high concentration of metal ions” in the blood of patients who received it.


DePuy never disclosed the F.D.A. ruling to regulators in other countries where it was still marketing the resurfacing version of the implant.


During a part of that period, Mr. Ekdahl was overseeing sales in Europe and other regions for DePuy. When The Times article appeared last year, he issued a statement, saying that any implication that the F.D.A. had determined there were safety issues with the A.S.R. was “simply untrue.” “This was purely a business decision,” Mr. Ekdahl stated at that time.


This article has been revised to reflect the following correction:

Correction: January 30, 2013

An earlier version of this article, in the summary, described the start of the DePuy trial incorrectly. It began last week, not this week.

LaHood will resign as Transportation secretary









WASHINGTON — Transportation Secretary Ray LaHood, a former lawmaker from Illinois and the last Republican left in President Obama's first-term Cabinet, announced Tuesday he was stepping down once a replacement was confirmed.


Among those mentioned as a possible successor is Los Angeles Mayor Antonio Villaraigosa, whose second and final term ends June 30. He has sought to establish himself as a national leader on transportation and made improving L.A.'s transit system a cornerstone of his tenure.


Villaraigosa played a key role in crafting a provision in last year's federal transportation bill designed to speed up projects around the country, including in Los Angeles. He was also one of the most prominent Latino supporters for Obama, who has been under pressure to appoint Latinos to his Cabinet. The former California Assembly speaker was chairman of the Democratic National Convention in Charlotte, N.C., last summer.





The mayor is traveling in South Korea; his office said he could not be reached for comment about the opening.


A longtime ally and another former Assembly speaker, Fabian Nuñez, would not confirm whether Villaraigosa had been approached about a Cabinet position but said he believed the mayor would, if one was offered, serve his full term.


"He has his two feet solidly placed on the ground," Nuñez said, adding that Villaraigosa feels he would "have an obligation to finish out his term as mayor. That's first and foremost."


The White House declined to discuss potential Cabinet nominees, but former Michigan Gov. Jennifer Granholm also has been mentioned as a replacement. Like Villaraigosa, Granholm was a key surrogate for Obama and a speaker at the last Democratic convention.


In a note to department staff, LaHood said he would remain until he was officially replaced to ensure "a smooth transition for the department and all the important work we still have to do."


The former seven-term congressman from Peoria, Ill., has led the department since 2009, but stated in 2011 that he did not plan to serve in the president's second term and would retire from public service. The president has another Republican on deck for his second term — former Sen. Chuck Hagel of Nebraska, whom Obama has nominated to lead the Pentagon. The other Republican in Obama's first-term Cabinet, Defense Secretary Robert M. Gates, left in 2011.


Despite his party affiliation, LaHood's views were often out of step with those of his former Republican colleagues, and his appointment did little to boost the president's standing with the opposition.


In his note, LaHood named among his top accomplishments his work to reduce distracted driving and combat pilot fatigue. He also listed his support for high-speed rail and more than $50 billion spent on transportation projects as part of the president's stimulus measure, a program reviled by Republicans, who see it as an example of wasteful federal spending.


"We helped jump-start the economy and put our fellow Americans back to work," LaHood wrote. "Our achievements are significant."


In an interview, LaHood said the biggest battle for his successor would not be over policy but money. The new secretary will have to find a way to fund highway construction and maintenance when the federal 18.4-cent-per-gallon gasoline tax isn't bringing in as much as it used to because vehicles are more fuel-efficient. There is strong opposition to raising the tax, which was last increased in 1993.


LaHood had pushed a five-year transportation funding bill, but had to settle for a two-year bill.


"The funding is the big question. Everyone knows what needs to be done in transportation in America. But the debate will be how to pay for it," LaHood said. "The American people are way, way ahead of the politicians on this. They're ready to have their potholes fixed … and they know it takes resources."

<em>The Hobbit</em> Earns More in Worldwide Box Office Than <em>Fellowship</em> or <em>Two Towers</em>



Movie critics of America, foreign audiences would just like to remind you that you’re not the boss of them, thank you very much. After all, not only did the critics complain when Peter Jackson expanded J.R.R. Tolkien’s The Hobbit into three movies (although, please remember: it could be worse), but the first of those movies failed to make the grade for many professional moviegoers, with this particular parish describing it as “attempting to recreate the Lord of the Rings trilogy with the nostalgic desperation of a college freshman trying to get back together with his high school girlfriend.”


So, you’d think that such a disappointing movie would be a flop at the box office, right? Guess again: As of this last weekend, The Hobbit: An Unexpected Journey has made more money worldwide than either Lord of the Rings: The Fellowship of the Ring or Lord of the Rings: The Two Towers managed in their entire time in movie theaters.


The international box office total for The Hobbit is currently $939,862,965, with almost 69 percent of that amount coming from non-U.S. audiences ($646,300,000, to be specific), continuing the upwards trend of Jackson’s Middle-earth movies. In comparison, The Fellowship of the Ring made $869,349,688 in terms of worldwide box office ($555,985,574 of which came from moviegoers outside of the U.S.; that’s 64 percent of the total for the less math-inclined amongst you), and The Two Towers collected a total of $923,285,627 from the world’s box office, with 63.2 percent of that amount ($583,495,746) coming from non-domestic release.


The only Tolkien movie to have made more money worldwide than The Hobbit is 2005′s Lord of the Rings: Return of the King, which grossed a total of $1,119,110,941 internationally during its time in theaters, with 66.3 percent of that – or $742,083,616 in practical terms – coming from non-American theaters.


In the U.S. alone, things are a little different. Currently, The Hobbit is lagging behind all three of Jackson’s earlier Tolkien movies, with “just” $293,562,965 in domestic box office, although there are all manner of reasons for that, not least of which is the fact that it is still in the middle of its theater run, only in release for 46 days versus the 243 days, 250 days and 170 days that Fellowship, Towers and Return enjoyed, respectively.


At current rate — it made $8,948,729 last week alone, and remains in the box office top 10 more than a month after release — it’s likely that The Hobbit will end up eclipsing The Fellowship of the Ring (Total domestic gross: $313,364,114) at least before leaving theaters, if not also The Two Towers (Total domestic gross: $339,789,881). Return of the King, however, can likely relax on its throne made of the $377,027,325 it brought in from American audiences during its time in theaters.


So, what can be learned from this? Perhaps we should chalk it up to the power of a recognizable brand; note that each successive Lord of the Rings movie was more financially successful than the one before, and that The Hobbit was seemingly unaffected by poor reviews ahead of release. In fact, it had the most impressive U.S. opening weekend, with $84,617,303 — significantly higher than even Return of the King‘s $72,629,713 and almost twice that of Fellowship of the Ring‘s $47,211,490.


Some things may simply be critic-proof, which likely comes as a relief to Warner Bros. with two more Hobbits waiting in the wings for 2013 and 2014 respectively. If the box office returns hold up, maybe talk of a final trilogy based upon material in The Silmarillion won’t seem as outlandish after all.

Muse to play anniversary gig for War Child charity






LONDON (Reuters) – British rock band Muse will headline a gig in London next month to mark the 20th anniversary of War Child, a charity that aims to protect young victims of conflicts around the world.


The gig on February 18 at the Shepherd’s Bush Empire will be the fifth time War Child has staged a concert in association with the BRIT Awards, Britain’s top pop honors which take place this year at the O2 Arena on February 20.






War Child is to receive the inaugural Special Recognition Award at the ceremony, while Muse has been nominated for best British group and best British live act.


Muse’s song “Survival” was chosen as the official song for the Olympic Games in London last year.


The BRIT Awards Concerts at the 2,000-capacity Empire have raised more than 600,000 pounds ($ 945,000) for War Child and included performances from Coldplay, The Killers, Blur and Kasabian.


“We are proud to have a continuing association with War Child, who have been doing amazing work over the last 20 years,” said Muse lead singer Matt Bellamy.


“It’s great to see their efforts being recognized at this year’s BRITs and we are really looking forward to playing this special show for them,” he added in a statement.


War Child UK says it has changed and saved the lives of some 800,000 children in war-affected countries including Bosnia, Rwanda, Afghanistan and Iraq.

Super Bowl — At Media Day, Spotlight on Head Injuries Grows





NEW ORLEANS — It has become a staple of Super Bowl week, as much a part of the pregame to the N.F.L.’s biggest event as the annual media day: a discussion of how football is being affected by head injuries and the mounting evidence that long-term brain damage can be linked to injuries sustained on the field.




Years ago, players rarely spoke about the issue and league officials dismissed suggestions that on-field injuries could lead to life-altering health problems. Now, however, the league is facing lawsuits from thousands of former players, rules are being instituted in an attempt to diminish injuries on the field and even President Obama has said that the way football is played will have to change. This week, Bernard Pollard, a hard-hitting safety for the Baltimore Ravens, created a stir by saying that the N.F.L. would not exist in 30 years because of the rules changes designed with safety in mind, but that he also believed there would be a death on the field at some point.


At media day Tuesday, players reacted to the comments made by Pollard and Obama, with some agreeing with Pollard that recent rules changes would change the sport to such an extent that it would be less entertaining and lead to a loss of popularity. Pollard stood by his comments. He added, however, that while he was comfortable with the physical risk he was taking by playing football, he was not sure he would want future generations, including his 4-year-old son, to follow his example.


“My whole stance right now is that I don’t want him to play football,” Pollard said. “Football has been good to me. It has been my outlet. God has blessed me with a tremendous talent to be able to play this game. But we want our kids to have things better than us.”


He said he did not want his son to go through the aches and pains caused by the physicality of the game.


“You keep playing football, you’re going to have your injuries, no one is exempt from that,” he said. “You’re going to have concussions. You’re going to have broken bones. That’s going to happen. But I think for the most part, we know what we signed up for.”


The sentiment was echoed by Baltimore quarterback Joe Flacco. “I play the game and I understand that I’m going to get hit,” Flacco said. “Just because they fine the guys is not going to stop them from hitting me. I find it tough to fine people who are doing their job.”


In a recent interview with The New Republic, Obama expressed concern about on-field injuries, though he added that N.F.L. players were grown men who are “well-compensated for the violence they do to their bodies.”


The president added: “I think that those of us who love the sport are going to have to wrestle with the fact that it will probably change gradually to try to reduce some of the violence. In some cases, that may make it a little bit less exciting, but it will be a whole lot better for the players, and those of us who are fans maybe won’t have to examine our consciences quite as much.”


While many current players seem focused on rules changes and how they will affect the nature of the game, more than 4,000 former N.F.L. players have filed a lawsuit against the league, contending that it knew hits to the head could lead to long-term brain damage but did not share that information with players. The judge in the case said Tuesday that she would hear oral arguments April 9 regarding the league’s motion to dismiss the lawsuit. The family of Junior Seau, a former star linebacker who shot and killed himself last year, has also sued the N.F.L., claiming it failed to inform players about the risks of brain injury.


Pollard’s counterparts on the San Francisco 49ers, safeties Dashon Goldson and Donte Whitner, considered one of the hardest-hitting tandems in the N.F.L., thought the key was not removing big hits, but making sure the hits that are delivered are legal.


“You can be vicious and you can hit people hard, but do it the right way,” Whitner said. “For the most part, you know what you can and cannot do. Do you want to go out there and do the right things or do you want to make that big hit to gain a big name? That’s what it comes down to.”


Ravens guard Marshal Yanda said he thought the topic was so personal for Pollard because of the unique nature of being a hard-hitting defensive back, one of the positions most affected by the league’s attempts to increase player safety.


“I think Bernard is frustrated because he plays a tough position where it’s a bang-bang play and he’s getting fined,” Yanda said. “That’s a tough deal as far as him playing football his whole life knowing how to play one way and then all of a sudden you have to change.”


One of the few people to disagree entirely with Pollard’s view that skewing the rules to protect offensive players would harm the league was Warren Sapp, a retired defensive tackle who at one point went by the Twitter handle @QBKilla. He said a desire for points would always result in defenses being limited.


“They like points,” Sapp said. “I like it too. You’re going to have to make some key stops here and there but it’s an offensive game, no doubt about it.”

Media Decoder Blog: CNN President Tries to Repeat Success in A.M. News

Two decades ago, a young producer named Jeff Zucker helped a down-on-its-luck “Today” show regain its ratings mojo and start what became a 16-year winning streak. More recently, he was a sounding board for Ben Sherwood, the president of ABC News, as Mr. Sherwood’s “Good Morning America” finally ended the “Today” show’s streak.

Now, Mr. Zucker is assembling a new morning show for CNN, the first of several building blocks for the ailing cable news channel. On Tuesday, he hired Chris Cuomo, a former news anchor on “G.M.A.,” to be a co-anchor of the new unnamed show, and is expected to begin in the spring. Mr. Zucker wants to pair Mr. Cuomo with Erin Burnett, another veteran of the morning shift.

Mr. Zucker, who formally took over CNN Worldwide last week after his appointment as president last November, declined an interview request. But his decision to scrap “Starting Point,” CNN’s morning show, and start over turned heads in the television industry on Tuesday. Agents and anchors said it conveyed the message that “he’s not wasting any time.”

CNN is one of the most valuable brands in the world, but its ratings in the United States have collapsed in the face of competition from other cable channels and the Internet. “Starting Point,” for example, had just 234,000 viewers on a typical morning in 2012, the channel’s lowest total viewer number in that time slot in more than a decade. Of those, just 96,000 were between the ages of 25 and 54, the group that cable news advertisers try to reach.

For Mr. Zucker, who rose from “Today” to run all of NBC Universal in the 2000s, before being replaced when Comcast took control of the company two years ago, the chance to turn around CNN’s morning ratings represents a test: long after leaving “Today,” can he revitalize another morning show for another network?

TMZ first reported Mr. Cuomo’s impending move on Monday night. He wrote on Twitter on Tuesday, “I have a great chance to be the first word on what matters to you every morning.”

His brother, Gov. Andrew M. Cuomo of New York, said in a radio interview that CNN was a better fit than ABC. “He’ll be on every day, so there will be a certain relevance to what he’s doing,” Governor Cuomo said.

Chris Cuomo has been a co-anchor of the weekly ABC newsmagazine “20/20” for the last three years. David Muir, the anchor of ABC’s weekend “World News,” will add “20/20” to his duties now. Mr. Cuomo, who previously spent three years as the news anchor on “G.M.A.,” was in the running for the co-host job on that show when Diane Sawyer left for the evening newscast “World News” in 2009. But the job went instead to George Stephanopoulos.

At CNN, a unit of Time Warner, Mr. Cuomo will have a new opportunity to lead a morning newscast. As it seeks a bigger audience in the mornings, however, CNN risks irritating the audience it already has by making sweeping changes. That happened 12 months ago when it gave up on a 10-year-old show, “American Morning,” and created “Starting Point.”

Soledad O’Brien, the anchor for the last 12 months, has been widely praised for her political interviews despite the program’s relatively low ratings. The show’s defenders say it never received the internal support and the external marketing it had been promised. They imply that it was not given a chance to succeed. Its detractors, however, say it was a bland copy of MSNBC’s “Morning Joe,” a show that, coincidentally, Mr. Zucker supported when he ran NBC Universal.

A CNN spokeswoman said in an e-mail Tuesday, “Soledad is very important to the network, and we’re discussing various options with her.”

Pairing Ms. Burnett with Mr. Cuomo would create another hole in CNN’s weekday schedule. Ms. Burnett is best known for her years at CNBC, where she and Mark Haines were at the helm of the midmorning markets newscast “Squawk on the Street” from 2005 to 2011. She is now the anchor of the 7 p.m. hour on CNN. But the hour has suffered like “Starting Point” and the rest of the channel’s schedule. CNN declined to comment on Ms. Burnett’s status on Tuesday.

Mr. Cuomo is the third prominent name from ABC to be hired by CNN in the last year. The first was John Berman, a longtime ABC correspondent, who now co-hosts “Early Start,” the predawn newscast that precedes “Starting Point.” The second was Jake Tapper, the chief White House correspondent for ABC.

Mr. Zucker had a role in signing Mr. Tapper, who will begin anchoring a daily program for CNN this year. Now Mr. Zucker is figuring out where Mr. Tapper and CNN’s other hosts belong on the schedule. Associates say Mr. Zucker wants both the daytime and prime time programs to be more entertaining and less dependent on the daily drip-drip-drip of stories about politics and overseas conflicts.

On Tuesday, Mark Whitaker, the managing editor of CNN Worldwide, stepped down, stating in an e-mail to staff members that Mr. Zucker “deserves his own team and management structure and the freedom to communicate one clear vision to the staff.” Mr. Whitaker was a top lieutenant of Jim Walton, Mr. Zucker’s predecessor.

The announcement last week of the hiring of the sports reporter Rachel Nichols from ESPN was a hint of what is to come under Mr. Zucker. He said in a statement then that Ms. Nichols would host a weekend sports program and called her hiring “an important step in expanding the range of programming and storytelling on CNN.”

Supernova Remnants: Dazzling Entrails of Violent Stellar Death

Even in death, there can be great beauty. Consider supernova remnants, the results of massive stars dying in great explosions, creating some of the most spectacular cosmic objects around.


Every 50 years or so, a star in our galaxy with more than 10 times the mass of our sun will expire. When such stars die, they go supernova, one of the most violent events in our universe. These explosions shoot off tons of material from the central star at up to 10 percent the speed of light.


Though the area surrounding stars seems empty, it is usually home to vast amounts of interstellar gas and dust. The supernova’s outburst runs into this surrounding material, creating a shockwave and heating it to temperatures greater than 10,000 Celsius. Over thousands of years, the local structure of the gas and dust shapes the stellar outpouring into shells, filaments, and other diffuse forms. Astronomers call these objects supernova remnants.


Supernova explosions and the remnants they leave behind have wide-ranging effects. They heat up the interstellar medium, creating complex chemistry out in space, and are responsible for accelerating protons and other atomic nuclei, which go zipping around the universe as cosmic rays. Perhaps most importantly, supernova explosions generate and liberate heavy elements, such as oxygen, carbon, and all metals, distributing them out into the wider cosmos. These elements eventually find their way into planetary systems, making life possible on at least one world that we know of.


Here, we take a look at some of the most famous and beautiful supernova remnants, giving you a chance to contemplate life, death, and cycles of renewal in the universe.

The supernova remnant N186 D appears as a bright pink spot at the top of this new image released by NASA on Jan. 28, spewing off tremendous amounts of X-rays. Located in the Large Magellanic Cloud about 160,000 light-years away, the remnant is blowing a huge bubble (the giant structure below the bright spot) as hot wind carves out a shock wave in the surrounding material.
