Well: Ask Well: Swimming to Ease Back Pain

Many people find that recreational swimming helps ease back pain, and there is research to back that up. But some strokes may be better than others.

An advantage to exercising in a pool is that the buoyancy of the water takes stress off the joints. At the same time, swimming and other aquatic exercises can strengthen back and core muscles.

That said, it does not mean that everyone with a case of back pain should jump in a pool, said Dr. Scott A. Rodeo, a team physician for U.S.A. Olympic Swimming at the last three Olympic Games. Back pain can have a number of potential causes, some that require more caution than others. So the first thing to do is to get a careful evaluation and diagnosis. A doctor might recommend working with a physical therapist and starting off with standing exercises in the pool that involve bands and balls to strengthen the core and lower back muscles.

If you are cleared to swim, and just starting for the first time, pay close attention to your technique. Work with a coach or trainer if necessary. It may also be a good idea to start with the breaststroke, because the butterfly and freestyle strokes involve more trunk rotation. The backstroke is another good option, said Dr. Rodeo, who is co-chief of the sports medicine and shoulder service at the Hospital for Special Surgery in New York.

“With all the other strokes, you have the potential for some spine hyperextension,” Dr. Rodeo said. “With the backstroke, being on your back, you don’t have as much hyperextension.”

Like any activity, begin gradually, swimming perhaps twice a week at first and then progressing slowly over four to six weeks, he said. In one study, Japanese researchers looked at 35 people with low back pain who were enrolled in an aquatic exercise program, which included swimming and walking in a pool. Almost all of the patients showed improvements after six months, but the researchers found that those who participated at least twice weekly showed more significant improvements than those who went only once a week. “The improvement in physical score was independent of the initial ability in swimming,” they wrote.

Airbus Abandons Plan to Use Controversial Batteries

PARIS — Faced with a potentially prolonged investigation into what caused batteries on two Boeing 787 Dreamliner jets to catch fire or emit smoke last month, Boeing’s European rival, Airbus, said Friday that it had abandoned plans to use the same battery technology on its forthcoming wide-body jet, the A350-XWB.

Airbus said that it began informing airline customers on Thursday that it would not move ahead with an original plan to use the lightweight lithium-ion batteries to power a number of the A350’s onboard systems, and would revert instead to a conventional battery, made of nickel-cadmium, that is already used extensively on existing Airbus models.

“Airbus considers this to be the most appropriate way forward in the interest of program execution and reliability,” said Marcella Muratore, an Airbus spokeswoman.

Airbus completed the assembly of its first test version of the A350 late last year and initial ground tests of that plane using the lithium-ion batteries had already begun at its factory in Toulouse, France. By switching gears now, the company said it hoped to be able to stick to its schedule of delivering the first aircraft in the second half of 2014.

Investigators at the U.S. National Transportation Safety Board have not determined the root cause of two episodes in January involving fire or smoke from the 787’s lithium-ion batteries, which are made by a Japanese company, GS Yuasa. The incidents prompted the U.S. Federal Aviation Administration to ground all 787s on Jan 17.

In recent weeks Airbus executives had indicated their concern that the continued uncertainty about the cause of the 787 battery problems, as well as the nature of any fixes that might be ordered by the F.A.A. and its European counterpart, the European Aviation Safety Agency, might endanger the A350’s development schedule, leading to potentially significant compensation payments to airlines.

Airbus currently has 617 orders for the A350 from 35 airline customers.

Ms. Muratore, the Airbus spokeswoman, stressed that the company remained confident that the lithium-ion battery system that it had been developing with its French supplier, Saft, was “robust and safe,” and added that Airbus planned to use lithium-ion batteries on the A350s it will use for flight tests scheduled to begin this summer.

The decision to revert to nickel-cadmium batteries, she said, was made purely for commercial reasons.

“As a result of making this decision now, Airbus does not expect it to impact the entry into service schedule,” Ms. Muratore said.

The Boeing 787 is the first commercial airliner to make extensive use of lithium-ion batteries. Prior to the A350, Airbus had only used the technology to power a limited number of auxiliary functions on its twin-deck A380 superjumbo, which entered service in 2007.

Battery makers have promoted lithium-ion batteries as being significantly lighter and faster to recharge that nickel-cadmium batteries. Promotional materials from both Yuasa and Saft have also described the technology as requiring significantly less maintenance that conventional batteries, reducing operating costs for airlines.

But investigations by Japanese and U.S. regulators in recent weeks have revealed that airlines had experienced multiple problems with the 787's batteries before the overheating incidents in January, raising questions about their reliability.

Battery experts say that while lithium-ion batteries weigh 30 percent to 40 percent less than conventional batteries, their contribution to the overall weight of a jetliner is minimal: The empty weight of a Boeing 787, for example, is about 242,000 pounds or 110,000 kilograms; its two lithium-ion batteries weigh 63 pounds each.

Ms. Muratore of Airbus said that it was too early to say what, if any, impact the battery switch may have on the A350's fuel-efficiency or other performance targets. But she stressed that weight ''was not a factor'' in the decision. She added that the dimensions of the nickel-cadmium batteries were not expected to be significantly larger than those of the four lithium-ion batteries they will replace, reducing the design adjustments that will have to be made.

Airbus said it was too early to estimate the financial impact of making the battery switch. But analysts said it was likely to be minimal compared to the potential burden of hundreds of millions of dollars in penalty payments to customers in the event of a delivery delay.

“I think this probably gets lost in the wash,” said Nick Cunningham, an aerospace industry analyst at Agency Partners in London. “You’re probably only talking about a few million dollars.”

He estimated that the added weight of the nickel-cadmium battery was probably equivalent to losing one passenger seat of payload. “That’s likely to be well within the margin of guarantees” on performance that Airbus has made to airlines, he said. “This seems like the thoroughly sensible thing to do.”

Aviation regulators have long known about the risks of lithium-ion batteries, which are more prone to overheating if improperly charged or discharged. Because of their unique chemistry, a fire that begins in one cell of a lithium-ion battery is difficult to extinguish and can rapidly spread to neighboring cells — a condition known as thermal runaway.

The technology was nonetheless approved by the F.A.A., the E.A.S.A. and regulators in other countries for use on the 787 in 2007, with the provision that Boeing employ a series of additional safeguards to contain smoke and fire in the event of an incident.

Airbus that it would continue to study the lithium-ion technology as it moves forward with the A350’s development and would “take on board” any relevant findings that resulted from the ongoing investigation of the Boeing 787 incidents.

This article has been revised to reflect the following correction:

Correction: February 15, 2013

An earlier version of this article mischaracterized incidents in January involving lithium-ion batteries in Boeing 787 Dreamliners. In one case a battery caught fire, and in another a battery emitted smoke; both batteries did not catch fire.

Vintage piano given Valentine's Day deadline

HALF MOON BAY, Calif. — The piano was delivered to its bluff-top perch under cover of fog nearly two weeks ago. It is scheduled to leave this coastal enclave in a burst of flames on Sunday.

In between the fog and the fire, musician and sculptor Mauro Ffortissimo has been treating his neighbors to an illicit outdoor concert series grandly dubbed Sunset Piano. Chopin, Debussy, a tango or two. The performances are timed to end the moment the sun sinks below the horizon.

He plays to cyclists and dog walkers, babies in strollers, his landlady in a folding chair, the charmed, the perplexed. Every night the battered baby grand has sounded just a little bit worse as the elements erode the aging, al fresco instrument. Every night, the audience has grown.

Ffortissimo (not his real name, but you probably figured that out already) had hoped to serenade the residents of Half Moon Bay for a month. But it didn't take long for reality to intrude on the 50-year-old artist's well-laid plans.

Two days after Ffortissimo and friends rolled the piano out to a scenic spit of city land, a code enforcement officer sent a warning via email. Someone had complained.

No permit, no piano.

The 90-year-old Estey "appears to be an unauthorized encroachment onto public property," wrote Lamonte Mack. If you can't prove the installation is authorized, he told Ffortissimo, "please remove the piano — and platform — within 10 (ten) days."

That made the deadline Valentine's Day, an occasion to celebrate love, if not misplaced musical instruments.

The artist legally known as Mauro Dinucci has taken the bad news in stride. Asked about the end of the piano during Tuesday night's crowded concert, he crowed: "Woo, hoo! Valentine's Day! Bring chocolate!" and promised that "before we burn this baby, we give it one last boat ride."

Thursday will be the piano's last scheduled bluff-side concert along the Coastside Trail at the end of Kelly Avenue. Friday, Ffortissimo said, he has been invited to play the instrument at the Half Moon Bay Yacht Club.

Saturday he'll give a sunset performance on the water, a nod to the piano's earlier owners who once sent it from California to Panama and back by sea. Sunday he plans to set the piano ablaze in the flower-strewn field behind his studio.

"The idea of the burning," Ffortissimo said, "is a cremation, to liberate the piano from its physical form … I just hope it won't be a 'Spare the Air' day."

Not everyone is as happy as Ffortissimo about the piano's upcoming freedom.

Mayor Rick Kowalczyk, who has yet to hear the Sunset Piano himself, said he was trying to "see if I can't get something done in the short term to allow Mauro to stay." Kicking the Estey off of the bluff, he said, "feels a little bit like a child has a lemonade stand and the city shuts it down."

On Tuesday evening, more than 100 music lovers gathered round as the sun — and the temperature — dropped. Two women danced together on the grass. Wine was sipped and beer chugged. Children ate cold pizza. Shorebirds glided by.

Far away from Half Moon Bay, President Obama was preparing to give his State of the Union address. Christopher Dorner was thought to be shooting it out with police.

But here on a bluff overlooking the Pacific Ocean, Susan Swanson of Redwood City poured white wine from a blue metal flask as Ffortissimo played Albinoni's "Adagio in G Minor." She'd read about the piano performance in the local newspaper, she said, "and it's the kind of news I like to read — good news.

"This to me is everything," said the trying-to-retire office manager. "It's a perfect moment. Once in a lifetime maybe. It's so odd, isn't it?"

<cite>The Monitor</cite> Heads to a Galaxy Far, Far Away

Not sure if you noticed, but it’s Star Wars Week on Wired. We’ve already dealt with the old movies and what the new movies will need, but it’s time to leave the big screen and get a handle on the best of the ancillary Star Wars products out there. To that end, we’ve got a new comic book that takes place between installments of the Original Trilogy, and two analog (or at least analog-inspired) games to take you back to your childhood. Beware, because we are descending to levels of Deep Nerd heretofore unplumbed.

Tasting notes for this week’s show:

• Brian Wood, the writer of Dark Horse’s new Star Wars ongoing comic, is also the man behind The Massive — the trade paperback of which is coming out next month. Highly recommended.


• Game publisher Fantasy Flight, maker of X-Wing Miniatures, also has a card game that’s pretty great. It’s a “living” card game rather than a conventional collectible game, meaning that you don’t have to pay through the nose chasing the best cards (though expansion packs are released periodically).


• A minute isn’t really enough to get across a full description of all the tables in Zen Studios’ new Star Wars Pinball, so here’s a deeper rundown.

Working on the Play section and editing features, Peter handles Wired magazine‘s pop culture and entertainment coverage: movies, TV, music, videogames, comic books and anything else that is absolutely integral to the survival of our species.

The New Old Age Blog: A New Commission: Time to Cheer or Yawn?

The fate of the Class Act, which would have established the nation’s first voluntary public long-term care insurance program, was sealed in 2011 when the Obama administration shut it down, essentially calling it unworkable.

As long as the language remained part of the Affordable Care Act, supporters allowed themselves to hope, or perhaps fantasize, that the administration might return to the subject. How to care for an aging population, and who pays for that and how, are questions that won’t go away.

But Congress quietly administered the coup de grâce last month, during the fiscal cliff negotiations. The budget deal stripped the Class Act language from the Affordable Care Act. R.I.P.

In its place — thanks to the intervention of Senator Jay Rockefeller, Democrat of West Virginia — the negotiators created a Commission on Long-Term Care, charged with developing plans for “a comprehensive, coordinated and high-quality system” ensuring long-term care for older adults and people with disabilities.

Its 15 members — three picks each for the president, the Senate majority and minority leaders, and the House speaker and minority leader — face a tight deadline. Within six months, they are supposed to recommend legislative or administrative actions, including actual legislative language. Then bills are to be introduced in both houses of Congress on the very next day they are in session.

Which sounds like urgency, but is it? Even Connie Garner, the longtime Kennedy staff member who directs the advocacy group called Advance Class, was skeptical. “What can you really do in six months?” she said. Actuaries and policy types had been working on the Class plan for 19 months before the plug was pulled. “And so what if you introduce a bill?” she went on. “You can introduce stuff and nothing happens.”

So when Advance Class held its monthly board meeting a few days after the Class Act officially bit the dust, Ms. Garner figured this push for a national long-term care approach was dead, along with her organization. She had prepared a valedictory, praising the group for at least putting the issue on the national agenda.

“But they said, ‘No, we’re going to keep Advance Class going; we’re going to fight the long fight,’ ” she recalled. So on we go.

Discouragingly, the commission has already hit delays: Its members were to be named within 30 days of the budget deal’s enactment, but only the Congressional Democrats have made appointments.

Senator Harry Reid, the majority leader, nominated a veteran health policy scholar, Judy Feder, who is now at the Georgetown University Public Policy Institute; the labor executive Laphonza Butler, who heads California’s United Long-Term Care Workers Union; and Javaid Anwar, a Nevada internist.

Representative Nancy Pelosi, the House minority leader, appointed Bruce Chernof, chief executive of the SCAN Foundation, which promotes quality care for the elderly; Judith Stein, founder of the Center for Medicare Advocacy; and George Vrandenburg, a retired corporate lawyer who has put his philanthropic muscle behind Alzheimer’s causes.

We have heard nothing yet from the White House or the Republican Congressional leadership.

Maybe that barely matters. “I can’t imagine anything coming out of this commission that won’t be totally forgotten a year from now,” said Jesse Slome, executive director of the American Association for Long-Term Care Insurance. “How many commissions have there been?”

Yet one thing that he and the proponents at Advance Class can agree on — maybe the only thing — is that this issue demands attention.

Otherwise, Mr. Slome says, we are stuck with what we have when it comes to older people who might need expensive care for 30 years, and disabled people who might need care for even longer. And what we have, he said, amounts to “a little here, a little there, a little Medicare, a lot of Medicaid, a little long-term care insurance and a lot of unpaid family caregiving.” (I would say very little long-term care insurance, and a vast amount of unpaid family care.)

Discussing the future of Medicare and Medicaid without including long-term care is pointless, Mr. Slome added. Ms. Garner notes that she meets frequently with Republicans and that they never dismiss the issue as unimportant.

Well, there’s a start.

DealBook: American and US Airways Announce Merger Deal

6:35 a.m. | Updated

Ending a yearlong courtship by US Airways, American Airlines agreed to merge with the smaller carrier, paving the way for the creation of the nation’s largest airline.

The boards of the companies have unanimously approved the deal, valued at $11 billion, according to a news release Thursday morning. A merger would bolster American’s domestic footprint, strengthen its presence in the Northeast and give it a bigger network to attract business travelers and corporate accounts.

Under the terms of the deal, US Airways’ shareholders will own 28 percent of the combined airline, while 72 percent of the stake will be held by AMR shareholders, creditors, labor unions and American employees.

The merger would create a rival with the size and breadth to compete against United Airlines and Delta Air Lines, which have grown through mergers of their own in recent years and are currently the biggest.

But while United and Delta went through bankruptcies and mergers over the last decade, American has been steadily losing ground while racking up losses that have totaled more than $12 billion since 2001. It was the last major airline to seek court protection to reorganize its business when it filed for bankruptcy in November 2011.

The wave of big mergers in the industry has created healthier and more profitable airlines that are now better able to invest in new planes and products, including Wi-Fi, individual entertainment screens and more comfortable seats for business passengers. But some consumer advocates said they worried that reducing the number of airlines would lead to higher fares over the long run and allow airlines to increase revenue by imposing new or higher fees.

The deal, which was completed in recent days, could be formalized as American leaves bankruptcy. W. Douglas Parker, the chairman and chief executive of US Airways, will take over as American’s chief executive. Thomas W. Horton, American’s current chairman and chief executive, will be chairman, though his tenure could be limited.

The merger still needs to pass several steps. It must be approved by American’s bankruptcy judge in New York. US Airways shareholders, who will also have to approve the deal.

In addition, it will be reviewed by the Justice Department’s antitrust division, though analysts expect regulators to clear the deal.

If approved, the nation’s top four airlines — American, United, Delta and Southwest Airlines — would control nearly 70 percent of the domestic market.

The merger is a victory for Mr. Parker. Over the last year, he has convinced American’s creditors that the carrier needed to expand its network to compete. In April, he won the critical backing of American’s three labor groups, which defied American’s management and publicly endorsed a deal with US Airways.

The biggest challenge for the merged company, which will be called American Airlines, will be to integrate operations over the next couple of years. That is no easy task since airline mergers are often rocky — involving complex technological systems, big reservation networks as well as large labor groups with different corporate cultures that all need to be seamlessly combined.

United angered passengers last year after a series of merger-related computer and reservation mistakes, and late and delayed flights.

Mr. Parker has done this before. In 2005, when he was the head of America West, he engineered a merger with the larger US Airways.

In this case, the merged American Airlines will still be based in Fort Worth and have a combined 94,000 employees, 950 planes, 6,500 daily flights, eight major hubs and total sales of nearly $39 billion. It would be the market leader on the East Coast, the Southwest and South America. But it would remain a smaller player in Europe, where United and Delta are stronger. The merger does little to bolster American’s presence in Asia, where it trails far behind its rivals.

American has major hubs in Dallas, Miami, Chicago, Los Angeles and New York. US Airways has hubs in Phoenix, Philadelphia and Charlotte, N.C., and has a big presence at Ronald Reagan National Airport in Washington.

In reviewing previous mergers, federal regulators have not focused on the overall size of the combined airline but instead looked at whether a merger would decrease competition in individual cities. To do so, regulators examine specific routes, or city-pairs, and look at whether a merger reduces the number of airlines there.

The last time the Justice Department challenged a merger was the proposed combination between United Airlines and US Airways in 2001. It rejected that on the ground that it would reduce consumer choice and possibly lead to higher fares.

Since then, the department has allowed a wave of big mergers that have reshaped the industry, said Alison Smith, a former antitrust official and now a partner in the law firm McDermott Will & Emery.

American and US Airways only have about 12 overlapping routes, a figure that is unlikely to set off regulatory opposition, she said. One problem, however, could come up at National Airport, where the combined carriers hold a market share of about 60 percent. There, regulators might request that American give up some takeoff and landing rights before approving the merger.

Regulators sought similar concessions from United at Newark Liberty International Airport after its merger with Continental Airlines.

It is also unclear whether American needs all of its combined hubs. Analysts pointed out that Phoenix was at risk because of its proximity to Dallas, since it makes little sense to have two big hubs so close to each other.

Despite the increased concentration, consumers can still expect to find vibrant competition, said William S. Swelbar, a research engineer at the Massachusetts Institute of Technology’s International Center for Air Transportation.

“We will have four very big, very vigorous competitors in the market,” he said.

Travelers are better served by bigger airlines offering more connecting flights and more destinations, analysts said. Consumers today can easily compare fares and shop for the cheapest flight online, which keeps airfares in check.

But Kevin Mitchell, chairman of the Business Travel Coalition, disagreed. He said that consumers would see few benefits to offset the merger’s negative impact — including “reduced competition, higher fares and fees and diminished service to small and midsize communities.”

Michael J. de la Merced contributed reporting.

Charred human remains found in burned cabin

Charred human remains
have been found in the burned cabin where police believe fugitive ex-cop
Christopher Dorner was holed up after trading gunfire with law enforcement, authorities
said.

If the body is identified
to be Dorner’s, the standoff would end a weeklong manhunt for the ex-LAPD
officer and Navy reserve lieutenant, who is accused of going on a
revenge-fueled spree following his firing by the Los Angeles Police Department several
years ago. Four people have died allegedly at Dorner’s hands.

The last burst of
gunfire Tuesday came after the suspect, attempting to flee law enforcement
officials, shot to death one San Bernardino County sheriff’s deputy and
seriously injured another. He then barricaded himself in a wooden cabin outside
Big Bear, not far from ski resorts in the snow-capped San Bernardino Mountains
east of Los Angeles, according to police.

PHOTOS: Manhunt for ex-LAPD officer

Just before 5 p.m., authorities smashed the cabin's windows, pumped in tear
gas and called for the suspect to surrender. They got no response. Then, using
a demolition vehicle, they tore down the cabin's walls one by one. When they
reached the last wall, they heard a gunshot. Then the cabin burst into flames.

Los Angeles Police Chief Charlie Beck said he would not consider the manhunt
over until a body was identified as Dorner.

TIMELINE: Manhunt for ex-LAPD officer

"It is a bittersweet night," said Beck as he drove to the hospital
where the injured deputy was located. He is expected to survive, but is expected to need several surgeries. "This could have ended
much better, it could have ended worse. I feel for the family of the deputy who
lost his life."

According to a manifesto Dorner allegedly posted on Facebook, he felt the LAPD
unjustly fired him several years ago, when a disciplinary panel determined that he lied
in accusing his training officer of kicking a mentally ill man during an
arrest. Beck has promised to review the case.

INTERACTIVE MAP: Searching for suspected shooter

Dorner, 33, vowed to wage "unconventional and asymmetrical
warfare" against law enforcement officers and their families, the
manifesto said. "Self-preservation is no longer important to me. do not
fear death as I died long ago."

Last week, authorities had tracked Dorner to a wooded area near Big Bear
Lake. They found his torched gray Nissan Titan with several weapons inside. The
only trace of Dorner was a short trail of footprints in newly fallen snow.

On Tuesday morning two maids entered a cabin in the 1200 block of Club View
Drive and ran into a man who they said resembled the fugitive, a law
enforcement official said. The cabin was not far from where Dorner's singed
truck had been found and where police had been holding press conferences about
the manhunt.

FULL COVERAGE: Sweeping manhunt for ex-cop

The man tied up the maids, and he took off in a purple Nissan parked near
the cabin. About 12:20 p.m., one of the maids broke free and called police.

Nearly half an hour later, officers with the California Department of Fish
and Wildlife spotted the stolen vehicle and called for backup. The suspect
turned down a side road in an attempt to elude the officers but crashed the
vehicle, police said.

A short time later, authorities said the suspect carjacked a light-colored
pickup truck. Allan Laframboise said the truck belonged to his friend Rick
Heltebrake, who works at a nearby Boy Scout camp.

Heltebrake was driving on Glass Road with his Dalmatian, Suni, when a
hulking African American man stepped into the road, Laframboise said.
Heltebrake stopped. The man told him to get out of the truck.

DOCUMENT: Read the manifesto

"Can I take my dog?" Heltebrake asked, according to his friend.

"You can leave and you can take your dog," the man said. He then
sped off in the Dodge extended-cab pickup — and quickly encountered two
Department of Fish and Wildlife trucks.

As the suspect zoomed past the officers, he rolled down his window and fired
about 15 to 20 rounds. One of the officers jumped out and shot a high-powered
rifle at the fleeing pickup. The suspect abandoned the vehicle and took off on
foot.

Police said he ended up at the Seven Oaks Mountain Cabins, a cluster of
wood-frame buildings about halfway between Big Bear Lake and Yucaipa. The
suspect exchanged gunfire with San Bernardino County sheriff's deputies as he
fled into a cabin that locals described as a single-story, multi-room
structure.

The suspect fired from the cabin, striking one deputy, law enforcement
sources said. Then he ducked out the back of the cabin, deployed a smoke bomb
and opened fire again, hitting a second deputy. Neither deputy was identified
by authorities. The suspect retreated back into the cabin.

The gun battle was captured on TV by KCAL-TV Channel 9 reporter Carter Evans, who said
he was about 200 feet from the cabin. As Evans described on air how deputies
were approaching the structure, he was interrupted by 10 seconds of gunfire.

Deputies drew their weapons and sprinted toward Evans. Someone yelled for
him to move — then about 20 more seconds of shooting erupted.

"Hey! Get … out of here, pal," someone shouted. Evans was
unharmed.

The gunfire gave way to a tense standoff. Mountain residents locked their
doors and hunkered down.

Holly Haas, 52, who lives about a mile from where the shootout unfolded,
said she heard helicopters buzzing on and off until about 3:30. One dipped so
close to her home, she said, "I could throw a rock and hit it."

Others watched the standoff unfold on television. At her home, Candy Martin
sat down to watch TV when, to her surprise, she spotted her rental cabin
on-screen — where the suspect was believed to be holed up.

She contacted police and told them that the furnished, 85-year-old cabin had
no cable, telephone or Internet service. No one had booked it for Monday.

"There should have been nobody," she recalled saying. "Nobody
in any way."

Within hours, authorities moved in on the cabin. The fire broke out, setting
off ammunition that had apparently been inside. On TV, viewers saw only the
orange flames and curls of black smoke.

LAPD Chief Beck said his officers have been providing
around-the-clock protection for more than 50 people thought to be Dorner's
targets since the manifesto was discovered.

Police say Dorner's first victims were the daughter of the retired LAPD
official who represented him at his disciplinary hearing and her fiance. Monica Quan and Keith Lawrence were
found shot to death Feb. 3 in their car in their condo complex's parking structure.

Days later, Dorner allegedly attempted to steal a boat in San Diego in a
failed bid to escape to Mexico. By Feb. 7, authorities said, he had fled to the
Inland Empire. In Corona, police said, he fired at an LAPD officer searching
for him at a gas station. About half an later, he allegedly opened fire on two
Riverside officers, killing Michael Crain, 34, and injuring his partner.

Early on in the manhunt, officers mistakenly fired on three people in the
Torrance area — two Latina women and a white man — while searching for Dorner,
who is 6 feet tall and 270 pounds.

After his truck was found in Big Bear, authorities swarmed the area, where
many cabins sit empty during the winter.

At the height of the search, more than 200 officers scoured the mountain,
while others sifted through more than 1,000 tips that poured in after officials
offered a $1-million reward.

Just as some officials began to speculate that the former cop had failed to
survive in the wilderness, Dorner apparently surfaced.

Why Netflix has “no motivation” to release ratings for “House of Cards”

NEW YORK (TheWrap.com) – Netflix has ‘no motivation’ to disclose viewership numbers for its original shows regardless of their success, chief creative officer Ted Sarandos said on Tuesday. Speaking at AllThingsD’s conference in Laguna Beach, Sarandos both mocked Nielsen numbers and insisted that Netflix has no need to toot its own horn.

“I honestly have no motivation to do it,” Sarandos said of releasing numbers. “I don’t sell ads, so ratings don’t matter in that way.”

The question has surfaced repeatedly since Netflix released “House of Cards,” an expensive and well-received original show created by Beau Willimon and starring Kevin Spacey. While Sarandos said the show has been the most watched show on Netflix in every country where the service is available, he would not go much further.

Entertainment executives are particularly curious about the show’s performance to gauge Netflix’s foray into original programming and to compare its audience to that of shows on regular TV. Netflix will soon release other new series from successful Hollywood talent, including a new season of “Arrested Development.” The show’s creator Mitch Hurwitz and cast member Will Arnett joined Sarandos on stage during the session as well.

Sarandos gave several explanations for why Netflix has no reason to get into the numbers game. For one, they don’t sell advertisements against specific shows, so ratings have no impact on their bottom line. They don’t sell their shows to cable operators either, so they don’t need ratings to justify charging a certain fee. They make money from subscriptions and ratings have no impact on those numbers.

Netflix customers also watch the shows differently than they do normal television since they can watch them at any time on many devices. Sarandos said comparing Netflix ratings and TV ratings would be like apples and oranges.

When a reporter pressed Sarandos on the issue, he remarked that actors don’t believe in Nielsen numbers anyways. Arnett then commented that creative people just want to tell stories and welcome a new way of doing so.

When asked what he does when Spacey calls to ask about numbers, Sarandos replied, “I don’t tell him. I just tell him I’m thrilled.”

Well: Getting the Right Dose of Exercise

Phys Ed

Gretchen Reynolds on the science of fitness.

A common concern about exercise is that if you don’t do it almost every day, you won’t achieve much health benefit. But a commendable new study suggests otherwise, showing that a fairly leisurely approach to scheduling workouts may actually be more beneficial than working out almost daily.

For the new study, published this month in Exercise & Science in Sports & Medicine, researchers at the University of Alabama at Birmingham gathered 72 older, sedentary women and randomly assigned them to one of three exercise groups.

One group began lifting weights once a week and performing an endurance-style workout, like jogging or bike riding, on another day.

Another group lifted weights twice a week and jogged or rode an exercise bike twice a week.

The final group, as you may have guessed, completed three weight-lifting and three endurance sessions, or six weekly workouts.

The exercise, which was supervised by researchers, was easy at first and meant to elicit changes in both muscles and endurance. Over the course of four months, the intensity and duration gradually increased, until the women were jogging moderately for 40 minutes and lifting weights for about the same amount of time.

The researchers were hoping to find out which number of weekly workouts would be, Goldilocks-like, just right for increasing the women’s fitness and overall weekly energy expenditure.

Some previous studies had suggested that working out only once or twice a week produced few gains in fitness, while exercising vigorously almost every day sometimes led people to become less physically active, over all, than those formally exercising less. Researchers theorized that the more grueling workout schedule caused the central nervous system to respond as if people were overdoing things, sending out physiological signals that, in an unconscious internal reaction, prompted them to feel tired or lethargic and stop moving so much.

To determine if either of these possibilities held true among their volunteers, the researchers in the current study tracked the women’s blood levels of cytokines, a substance related to stress that is thought to be one of the signals the nervous system uses to determine if someone is overdoing things physically. They also measured the women’s changing aerobic capacities, muscle strength, body fat, moods and, using sophisticated calorimetry techniques, energy expenditure over the course of each week.

By the end of the four-month experiment, all of the women had gained endurance and strength and shed body fat, although weight loss was not the point of the study. The scientists had not asked the women to change their eating habits.

There were, remarkably, almost no differences in fitness gains among the groups. The women working out twice a week had become as powerful and aerobically fit as those who had worked out six times a week. There were no discernible differences in cytokine levels among the groups, either.

However, the women exercising four times per week were now expending far more energy, over all, than the women in either of the other two groups. They were burning about 225 additional calories each day, beyond what they expended while exercising, compared to their calorie burning at the start of the experiment.

The twice-a-week exercisers also were using more energy each day than they had been at first, burning almost 100 calories more daily, in addition to the calories used during workouts.

But the women who had been assigned to exercise six times per week were now expending considerably less daily energy than they had been at the experiment’s start, the equivalent of almost 200 fewer calories each day, even though they were exercising so assiduously.

“We think that the women in the twice-a-week and four-times-a-week groups felt more energized and physically capable” after several months of training than they had at the start of the study, says Gary Hunter, a U.A.B. professor who led the experiment. Based on conversations with the women, he says he thinks they began opting for stairs over escalators and walking for pleasure.

The women working out six times a week, though, reacted very differently. “They complained to us that working out six times a week took too much time,” Dr. Hunter says. They did not report feeling fatigued or physically droopy. Their bodies were not producing excessive levels of cytokines, sending invisible messages to the body to slow down.

Rather, they felt pressed for time and reacted, it seems, by making choices like driving instead of walking and impatiently avoiding the stairs.

Despite the cautionary note, those who insist on working out six times per week need not feel discouraged. As long as you consciously monitor your activity level, the findings suggest, you won’t necessarily and unconsciously wind up moving less over all.

But the more fundamental finding of this study, Dr. Hunter says, is that “less may be more,” a message that most likely resonates with far more of us. The women exercising four times a week “had the greatest overall increase in energy expenditure,” he says. But those working out only twice a week “weren’t far behind.”
