Algerian military launches raid to rescue hostages

CAIRO -- The Algerian military on Thursday launched a raid to retake a natural gas complex from Islamic militants who seized the compound a day earlier and took scores of hostages, including Americans, Britons and Japanese.

Conflicting reports of casualties emerged. The Algerian news agency reported that as many as 45 hostages, including Americans, escaped the site in the Sahara Desert near the Algerian-Libyan border. Algeria media reports later in the day said that only between four and six foreign hostages were freed and that were a number of "victims."

A Mauritanian news organization quoting an extremist spokesman suggested that gunfire from Algerian military helicopters at two vehicles attempting to flee the compound killed 35 foreigners and 15 kidnappers, including the militant group’s leader.

The militant assault on the Western-run gas compound reportedly was carried out as retaliation for French military strikes against Islamist rebels seeking to overthrow the government in neighboring Mali. The Al Qaeda-linked militants, who belonged to a group called the Signed-in-Blood Battalion, reportedly threatened to blow up the site if Algerian commandos attempted to free the hostages.

Hundreds of Algerian soldiers ringed the remote compound and helicopters skimmed above, reports said. Algerian officials had earlier said they would not negotiate with the extremists, who reportedly had asked for safe passage into neighboring Libya.

"The authorities do not negotiate, no negotiations," Algerian Interior Minister Daho Ould Kablia said on state television. "We have received their demands, but we didn't respond to them."

The Algerian military's raid on the complex marked a stunning twist in a drama that had raised fears of a long siege and highlighted the dangerous Islamist extremism stretching from Mali across the mountains and lawless deserts of North Africa.

The Algerian government was under pressure from the United States, Britain and other countries whose nationals were taken hostage to end the ordeal.

But the military raid appeared to have caught some by surprise. British Prime Minister David Cameron's office said that he would have preferred to have been told in advance of the operation.

In a phone interview with Al Jazeera, two European hostages urged the Algerian army to pull back from the site.

 "We are receiving care and good treatment from the kidnappers. The [Algerian] army did not withdraw and they are firing at the camp," said one of the hostages. "There are around 150 Algerian hostages. We say to everybody that negotiations is a sign of strength and will spare many any loss of life."

The natural gas field complex at In Amenas, which supplies Europe and Turkey, is a joint venture operated by BP, the Norwegian firm Statoil and Sonatrach, the Algerian national oil company.

Massacres Alter Social Structure of Africa's Elephants

By Virginia Morell, ScienceNOW

Poachers are slaughtering elephants across Africa at an unprecedented pace. But scientists tracking the animals’ carcasses—their faces and ivory hacked away—are seldom able to explain in detail what these deaths mean to the pachyderms’ populations and social structure. Now, a 14-year study of elephants in northern Kenya concludes that the adult behemoths are more likely to die at the hands of humans than from natural causes. At the same time, the elephants have responded to the heavy poaching with a baby boom, providing the researchers some hope for the jumbos’ survival.

“Clearly it is the most detailed and comprehensive demographic analysis undertaken for any elephant population, and perhaps any wildlife population, at least in Africa,” says Norman Owen-Smith, an ecologist at the University of the Witwatersrand in Johannesburg, South Africa. It provides a base “for modeling the potential impacts of increased poaching” on other African elephant populations, which are also suffering from illegal killing.

In 1997, the scientists began a study on elephant behavior in two adjacent national reserves, Samburu and Buffalo Springs, which together measure 220 square kilometers. The parks’ elephants were accustomed to vehicles and easy to study; they had also recovered from heavy poaching in the 1970s. At the beginning of the study, illegal killing was rare. “We might lose one big male a year,” says George Wittemyer, a wildlife biologist at Colorado State University, Fort Collins, and the study’s lead author. “We thought the population was stable.” That changed in 2009 as poachers began shooting elephants en masse. The scientists then shifted their study to look at the effects the poaching was having on the elephants they knew.

At the study’s outset, the researchers focused on 934 individuals (509 females and 425 males). The team used a standard method for identifying each elephant, noting each animal’s unique markings on its ears and face, as well as the shape of its tusks. Then each week, from 1997 to 2011, the researchers drove along five, 20-kilometer routes inside the reserves and recorded the presence or absence of the study elephants. They considered any animals that they didn’t spot for more than 3 years to be dead. The scientists seldom found the carcasses of these animals, but they investigated any dead elephants reported by tourists or rangers that were inside the parks or within 10 kilometers of the reserves’ boundaries.

Although the elephant population was increasing when the study began, it began to decline as poachers targeted the animals. The older elephants, which have larger tusks, were especially hard hit. In 2000, there were 38 males over 30 years old in the study population. By 2011, their number had dropped to 12—and of those, seven had matured into this age class. Older females also suffered huge losses, with almost half of those 30 years old dying between 2006 and 2011. By 2011, 56% of the elephants that were found dead had been poached, the team reports online today in PLOS ONE.

The poaching spree has also altered the elephants’ social organization, the study shows. When the work began, males made up 42% of the population; by 2011, they had been cut down to only 32%. And 10 of the 50 elephant family groups that the scientists were studying were effectively wiped out. “They no longer have any breeding females,” Wittemyer explains. “And so, the family group has disappeared, leaving surviving juveniles on their own.” These youngsters may join other families, or, without a leader to guide them, try to survive in sibling groups typically led by the oldest sister.

“Some elephants died from a bad drought that hit the region between 2009 and 2010,” Wittemyer adds. “But at least half of these deaths were due to poaching.” The poaching took place outside the reserves on lands that are largely unpatrolled. In addition to the reserve, the elephants roam over a vast area of more than 3500 square kilometers.

As grim as the data are, Wittemyer says they are “more representative of elephant populations across the continent today” than data collected in areas such as Kenya’s Amboseli National Park, where scientists have studied elephants since 1972. The Amboseli elephants are better protected than those in Samburu, although, they, too, have suffered significant losses from poachers. Long-term studies of elephants in South Africa’s Kruger National Park, where elephants have been culled but not poached, have focused more on the animals’ population dynamics than on individuals. The new Samburu study provides “a good comparison” with these studies, Wittemyer says, and is particularly useful these days because nearly all elephant populations are facing similarly high rates of poaching.

Wittemyer and his colleagues also suggest that their data show that the Samburu elephants have responded to the pressure from poaching with a baby boom. “There was a big jump in births in 2012,” Wittemyer says, “and a hiatus for a few months in the killings. So it looked like we were on the up-and-up.”

“Any evidence that contributes to understanding how or if elephant populations will be able to recover from these extreme mortality events is highly significant—and this paper does that,” says Phyllis Lee, an animal behaviorist at the University of Stirling in the United Kingdom.

But, Owen-Smith says, the Samburu elephants’ super reproductive performance is likely nothing more than a sign that their population is “well below the carrying capacity limits” of the region—meaning that a landscape that was once dense with elephants is now largely empty. And the killing has started again: Poachers shot 20 elephants in recent weeks in the Samburu region. As Joyce Poole, an ethologist and expert on elephant behavior in Nairobi, who directs the conservation organization ElephantVoices, puts it: “The study’s interesting population dynamics are overshadowed by a gruesome reality.”

Singer Elton John a father for second time

LONDON (Reuters) – British pop star Elton John announced on Wednesday he had become a father for the second time after the birth via a surrogate mother of Elijah Joseph Daniel Furnish-John.

The “Rocket Man” and “Candle in the Wind” singer and his partner David Furnish confirmed the news in a short statement on John‘s official website, which also provided a link to an article in Hello! magazine.

“Both of us have longed to have children, but the reality that we now have two sons is almost unbelievable,” said the couple, who entered a civil partnership in 2005.

“The birth of our second son completes our family in a most precious and perfect way,” they told Hello!.

John, 65, and Furnish, 50, are already parents to Zachary, who is two. Elijah was born in Los Angeles on January 11.

“I know when he goes to school there’s going to be an awful lot of pressure, and I know he’s going to have people saying, ‘You don’t have a mummy,’” John said of his decision to have another baby.

“It’s going to happen. We talked about it before we had him. I want someone to be at his side and back him up. We shall see.”

Ask Well: Help for the Deskbound

One of the problems with office work is that many of us are using chairs that don’t fit our bodies very well or give adequate support to the back, said Jack Dennerlein, a professor at Northeastern’s Bouvé College of Health Sciences in Boston who specializes in ergonomics and safety. If you are experiencing back pain, you may be able to adjust your chair to increase its lumbar support. A good office chair will have an adjustable seat pan that you can slide back and forth as well as adjustable back and height features. First, sit in the chair so the lumbar region of your back, your lower back, is resting on the back support. At the same time, your feet should be resting comfortably on the ground and the back of your knees should be about three-finger widths from the edge of the chair, said Dr. Dennerlein.

Some high-end chair brands have adjustable seat pans, including the Steelcase Leap chair, which retails for between $800 and $900 and offers an adjustable seat and plenty of lumbar support.

The Steelcase Criterion chair sells anywhere from $350 to $850 online, depending on the model, and boasts seven different adjustments “to offer support through the full range of dynamic seating postures.”

The HumanScale Freedom chair is the winner of several design awards and also has an adjustable seat pan as well as “weight-sensitive recline, synchronously adjustable armrests, and dynamically positioned headrest.” ($400 to $1,400)

The Herman Miller Aeron chair is also popular because it comes in small, medium and large sizes and claims a PostureFit design that “supports the way your pelvis tilts naturally forward, so that your spine stays aligned and you avoid back pain.” ($680 to $850)

If all that sounds really wonderful and really too expensive, there may be a simpler solution to ease your back pain at work. Invest $15 to $30 in a lumbar chair pillow to make sure your back is getting the support it needs even when you are not sitting in a $900 chair.

Lawmakers Seek Data on Energy Drinks

Three Democratic lawmakers on Thursday sent letters to 14 marketers of high-caffeinated energy drinks requesting data about the products’ ingredients and any company studies showing their risks and benefits to children and young people.

In recent months, the Food and Drug Administration has begun examining the safety of energy drinks following reports of several deaths and numerous injuries potentially associated with the products. The number of annual hospital emergency visits involving the drinks doubled from 2007 to 2011, according to a federal report released last week.

In addition, claims by drink producers that their proprietary “energy” formulations provide consumers with a physical and mental edge are coming under scrutiny. There is little scientific evidence, researchers say, that the drinks provide anything more than a high dose of caffeine similar to that found in a cup of strong coffee.

The letters were sent by Senators Richard J. Durbin of Illinois and Richard Blumenthal of Connecticut and Representative Edward J. Markey of Massachusetts to companies including Monster Beverage, Rockstar, Red Bull and Living Essentials, the distributor of 5-Hour Energy, a small, concentrated energy “shot” drink. Letters were also sent to PepsiCo, which sells Amp; Coca-Cola, which sells NOS; and Dr Pepper Snapple, which sells Venom Energy.

Among other questions in the letter, the lawmakers asked the companies to specify the total amount of caffeine in the energy beverages. Products like 5-Hour Energy that are marketed as supplements do not list the amount of caffeine used and producers use caffeine from a variety of sources such as synthetic caffeine, the guarana plant and tea extracts.

They also asked why the companies chose to market their energy product as either a beverage or a dietary supplement. The two regulatory categories have separate rules about ingredient disclosures and reporting of potential health risks.

The lawmakers also asked the companies to provide any studies that they have run or underwritten that examine the effect of energy drink use in children or young adults.

The few studies cited by energy drink companies to back their marketing claims have taken place among adults and have compared the effect of an energy drink to that of a placebo like flavored water.

Other public officials are looking into marketing claims of energy drink makers, including the attorney general of New York State and the city attorney for San Francisco.

L.A. councilman seeks ban on large-capacity gun magazines

Los Angeles City Councilman Paul Krekorian wants the city to explore the feasibility of banning the possession of high-capacity gun magazines, the first step toward instituting stricter city gun and ammunition laws.

Although the California penal code now prohibits the manufacture and sale of magazines that hold more than 10 bullets, Krekorian said in a council motion Tuesday that a ban on the possession of the magazines within city limits could further improve public safety.

"The element missing from the state prohibition on high-capacity magazines is possession," Krekorian said in an interview with The Times

---

FOR THE RECORD:
High-capacity gun magazines: An earlier online version of this article, and its headline, incorrectly stated that Councilman Paul Krekorian has asked the city to consider banning ammunition for high-capacity gun magazines. Krekorian has requested that the city research a ban on the high-capacity magazines themselves, not their ammunition.

---

Although gun rights advocates frequently describe high-capacity magazine bans as "feel-good" steps, Krekorian said prohibiting their possession would give police a way to stop potential mass shooters before a tragedy can take place.

"I'm not interested in doing something that will have no effect," Krekorian said. "I'm interested in doing something that will prevent the kinds of slaughters we experience too often -- whether it's school shootings, shootouts with the police or drive-bys by gangbangers."

Krekorian's motion cited the 1997 North Hollywood shootout -- during which two bank robbers fired thousands of automatic weapon rounds at responding officers -- as well as the recent Sandy Hook Elementary School shootings in Newtown, Conn.

The motion asks that the Los Angeles Police Department, the city attorney and the city legislative analyst look into the feasibility, effectiveness and benefits of such a ban.

It marks the first formal request by a council member to look into a potential ban, according to Krekorian's spokesperson.

Second Amendment advocates have widely decried city, state and federal high-capacity magazine bans. Representatives from both the Gun Owners of America and National Rifle Assn. have previously said the bans restrict the ability of law-abiding gun owners from defending themselves.

"If the city of Los Angeles is looking to find new ways to waste taxpayer money, a proposal along the lines of banning the possession of instruments currently legal to own would certainly be one way to do it," said Brandon Combs, executive director of Calguns Foundation, a California-based 2nd Amendment advocacy group.

Although Combs said it's reasonable to consider bans on "true high-capacity magazines" holding more than 30 bullets, bans on 10- to 20-bullet magazines being pushed into law across the country are infringing on the rights of gun owners to protect themselves.

Meanwhile, a ban would do nothing to curb the behavior of criminals, who probably will continue to use high-capacity magazines even where they are illegal, he said.

"These criminals who commit mass shootings are not interested in listening to the Los Angeles City Council," Combs said. "I'd like to see some evidence that suggests a ban on high-capacity magazines has any effect on crime at all."

He noted that other California cities -- including San Francisco and San Jose -- have also pushed new gun and ammunition restrictions in the wake of the Sandy Hook shooting.

While other Los Angeles City Council members have supported a national ban on assault weapons and called for city investment funds to sell any stock they might hold in companies that make or sell such guns, the request for this report is the first step toward curbing high-capacity magazine possession at the city level since the mass shooting in Connecticut.

The December shooting in Newtown, which left 27 dead, including 20 children and the gunman, and last week's shooting at Taft Union High School in Kern County have re-energized discussions of gun control measures among Los Angeles politicians.

Mayor Antonio Villaraigosa and LAPD Chief Charlie Beck bumped up the annual gun buyback program and have increased the police presence in schools. The mayor has also scheduled a news conference Wednesday to further address gun violence.

Meanwhile, all four mayoral hopefuls -- including current council members Jan Perry and Eric Garcetti -- have called for the renewal of the federal assault weapons ban.

Combs said if there was going to be a renewed conversation about gun control, he hopes the politicians who have added gun safety measures to their platforms and stump speeches open the discussion to 2nd Amendment advocates.

"Are these city officials going to invite us to the table? Or is this just going to be them passing restrictive gun laws they've already decided they want to see pass?" Combs said. "Hopefully, our elected officials are reaching out to gun rights organizations if they're truly interested in having a conversation."

See a Real-Life <em>Mario Kart</em> Race Complete With RFID Bananas, Power-Ups

What Mario Kart fan hasn’t secretly dreamed of playing a real-life version of the Mario Bros-themed racing game? But while most people would be content with renting regular go-karts and using their imaginations really, really hard, two Texas engineers, Hunter Smith and Ben James, decided to make the dream a reality by creating an ingenious live-action version of the Mario Bros-themed racing game.

Where things really get amazing, however, are the RFID-embedded power-up item boxes suspended over the track by pieces of rope, which allow the player to collect items like bananas and turtle shells modeled on the original Mario Kart game — and actually affect their performance in the race. The mushroom item, for example, wirelessly activates tiny Servo motors that enable go-karts to speed up by accessing 100 percent of their throttle power.

“Ben and I grew up playing Mario Kart on Super Nintendo and Nintendo 64 so we’re both big fans,” Smith, the co-founder of Austin Texas-based Waterloo Labs, told Wired. We got the idea for the real-life Mario because we work with First Robotics Competition and they use same controller, software and motors. We got a few extra kits so we asked ourselves ‘What can we do with these competition kits that would be fun?”

The system details and source code for the project are available on the Waterloo Labs website, which volunteers that while there is no permanent set-up for Real-Life Mario Kart for enthusiasts to visit, “we would be happy to help you build your own!”

Arnold Schwarzenegger is back, but can he flex Box-Office muscle?

LOS ANGELES (TheWrap.com) – Arnold Schwarzenegger is back at the box office, but will anyone notice? We’ll find out on Friday, when he debuts as a kick-ass small-town sheriff in “The Last Stand,’ his first starring role in nine years.

When Schwarzenegger famously delivered his “I’ll be back” line in 1984, it was as a time-traveling android in “The Terminator.” Following his stint as California governor and a very messy divorce from Maria Shriver complete with love child, his return as a box-office force seems almost as unlikely as his role as a time-traveling android.

But Hollywood has embraced the return of California’s 65-year-old former “Governator.” He has three films coming out in the next 12 months and Universal is developing “Triplets,” a sequel to the Danny DeVito-Schwarzenegger comedy “Twins,” as well as another “Conan the Barbarian” movie.

But whether the movie going public is as excited as Hollywood about Arnold‘s return is an open question.

Lionsgate is distributing “The Last Stand,” an action film with a reported $ 50 million budget.

Directed by Korean director Kim Jee-woon and written by Andrew Knauer and Jeffrey Nachmanoff, “The Last Stand” is the tale of an aging border-town lawman drawn into a showdown with a drug cartel kingpin. Johnny Knoxville, Forrest Whitaker and Eduardo Noriega co-star. It was produced by Leonardo Di Bonaventura and was acquired by Lionsgate back in 2009 before Schwarzenegger was involved. Liam Neeson was attached to star at one point.

Lionsgate has proven adept at marketing genre films, including “The Expendables” and Tyler Perry franchises, and last year’s “The Possession,” and that will help “The Last Stand.” Distribution chief Richie Fay tells TheWrap he’s confident Schwarzenegger‘s return will connect with the public.

“I’ve been in a number of screenings and at the premiere,” Fay told TheWrap Tuesday, “and the reaction to the film has been great. People are laughing at his one-liners, they seem very comfortable with Arnold back on the screen in his action mode.”

Fay has reason to be bullish. Schwarzenegger‘s most recent screen appearance was in another Lionsgate entry, the ensemble action film “The Expendables 2,” last August. That one has taken in more than $ 300 million worldwide. And he’ll be back – there we go, again – with Sylvester Stallone in “The Tomb,” for Lionsgate‘s Summit Entertainment in September.

Others aren’t so sure.

“I can’t see this film opening to more than the mid-teen millions,” Exhibitor Relations senior analyst Jeff Bock told TheWrap. “There’s not a lot of negative buzz, but people aren’t dying to see him come back, either. Bottom line, I don’t think he’ll inspire anywhere the level of passion he once did at the box office.”

If Lionsgate is to make money on “The Last Stand,” it appears foreign will be critical; analysts see the film topping out at $ 30 million domestically.

“Schwarzenegger is still a big deal overseas,” Bock said, “and that’s where this movie will make or break itself.

I could easily see it doing double whatever it does in the U.S.”

At this point in his career, the stakes for Schwarzenegger may be higher than they are for the studios. His paycheck for “The Last Stand” is reportedly in the $ 8 million to $ 10 million range, with some potential profit participation. That’s about half of what he commanded in his heyday for the “Terminator” films, “True Lies” and “Total Recall.”

Schwarzenegger‘s box-office clout was beginning to fade prior to his heading to Sacramento in 2003. His last film, “Terminator 3: Rise of the Machines” made $ 150 million domestically for Warner Bros. in 2003, but his two previous movies, “Collateral Damage” and “The Sixth Day,” topped out at $ 40 million and $ 34 million respectively.

Hollywood’s expectations have changed, too. Most of Schwarzenegger‘s hits were big summer movies, with budgets well over $ 100 million. “The Last Stand” cost half that, and its release on a moderate 2,800 screens in January, typically a soft time for new releases, is no accident. “Ten,” Schwarzenegger‘s third film, is scheduled for release on January 24, 2014, by Open Road Films.

“The Last Stand” is the first of three upcoming openings for action movies with older stars. Warner Bros. is opening “Bullet to the Head,” starring Stallone, on February 1. Bruce Willis stars in “A Good Day to Die Hard” from Fox on February 15.

The New Old Age: In Flu Season,Use a Mask. But Which One?

Face masks help prevent people from getting the flu. But how much protection do they provide?

You might think the answer to this question would be well established. It’s not.

In fact, there is considerable uncertainty over how well face masks guard against influenza when people use them outside of hospitals and other health care settings. This has been a topic of discussion and debate in infectious disease circles since the 2009 H1N1 flu pandemic, also known as swine flu.

As the government noted in a document that provides guidance on the issue, “Very little information is available about the effectiveness of facemasks and respirators in controlling the spread of pandemic influenza in community settings.” This is also true of seasonal influenza — the kind that strikes every winter and that we are experiencing now, experts said.

Let’s jump to the bottom line for older people and caregivers before getting into the details. If someone is ill with the flu, coughing and sneezing and living with others, say an older spouse who is a bit frail, the United States Centers for Disease Control and Prevention recommends the use of a face mask “if available and tolerable” or a tissue to cover the nose and mouth.

If you are healthy and serving as a caregiver for someone who has the flu — say, an older person who is ill and at home — the C.D.C. recommends using a face mask or a respirator. (I’ll explain the difference between those items in just a bit.) But if you are a household member who is not in close contact with the sick person, keep at a distance and there is no need to use a face mask or respirator, the C.D.C. advises.

The recommendations are included in another document related to pandemic influenza — a flu caused by a new virus that circulates widely and ends up going global because people lack immunity. That is not a threat this year, but the H3N2 virus that is circulating widely is hitting many older adults especially hard. So the precautions are a good idea, even outside a pandemic situation, said Dr. Ed Septimus, a spokesman for the Infectious Diseases Society of America.

The key idea here is exposure, Dr. Septimus said. If you are a caregiver and intimately exposed to someone who is coughing, sneezing and has the flu, wearing a mask probably makes sense — as it does if you are the person with the flu doing the coughing and sneezing and a caregiver is nearby.

But the scientific evidence about how influenza is transmitted is not as strong as experts would like, said Dr. Carolyn Bridges, associate director of adult immunization at the C.D.C. It is generally accepted that the flu virus is transmitted through direct contact — when someone who is ill touches his or her nose and then a glass that he or she hands to someone else, for instance — and through large droplets that go flying through the air when a person coughs or sneezes. What is not known is the extent to which tiny aerosol particles are implicated in transmission.

Evidence suggests that these tiny particles may play a more important part than previously suspected. For example, a November 2010 study in the journal PLoS One found that 81 percent of flu patients sent viral material through air expelled by coughs, and 65 percent of the virus consisted of small particles that can be inhaled and lodge deeper in the lungs than large droplets.

That is a relevant finding when it comes to masks, which cover much of the face below the eyes but not tightly, letting air in through gaps around the nose and mouth. As the C.D.C.’s advisory noted, “Facemasks help stop droplets from being spread by the person wearing them. They also keep splashes or sprays from reaching the mouth and nose of the person wearing them. They are not designed to protect against breathing in the very small particle aerosols that may contain viruses.”

In other words, you will get some protection, but it is not clear how much. In most circumstances, “if you’re caring for a family member with influenza, I think a surgical mask is perfectly adequate,” said Dr. Carol McLay, an infection control consultant based in Lexington, Ky.

By contrast, respirators fit tightly over someone’s face and are made of materials that filter out small particles that carry the influenza virus. They are recommended for health care workers who are in intimate contact with patients and who have to perform activities like suctioning their lungs. So-called N95 respirators block at least 95 percent of small particles in tests, if properly fitted.

Training in how to use respirators is mandated in hospitals, but no such requirement applies outside, and consumers frequently put them on improperly. One study of respirator use in New Orleans after Hurricane Katrina, when mold was a problem, found that only 24 percent of users put them on the right way. Also, it can be hard to breathe when respirators are used, and this can affect people’s willingness to use them as recommended.

Unfortunately, research about the relative effectiveness of masks and respirators is not robust, and there is no guidance backed by scientific evidence available for consumers, Dr. Bridges said. Nor is there any clear way of assessing the relative merits of various products being sold to the public, which differ in design and materials used.

“Honestly, some of the ones I’ve seen are almost like a paper towel with straps,” Dr. McLay said. Her advice: go with name-brand items used by your local hospital.

Meanwhile, it is worth repeating: The single most important thing that older people and caregivers can do to prevent the flu is to be vaccinated, Dr. Bridges said. “It’s the best tool we have,” she said, noting that preventing flu also involves vigilant hand washing, using tissues or arms to block sneezing, and staying home when ill so people do not transmit the virus. And it is by no means too late to get a shot, whose cost Medicare will cover for older adults.

Conversation: A Founder of the Soap Maker Method Discusses Its Sale

For Eric Ryan and Adam Lowry, the quest began in 2001 in what they call a “dirty little flat” in San Francisco, where the two childhood buddies from Detroit first plotted to disrupt the all-but-impenetrable cleaning products industry long dominated by giants like SC Johnson and Procter & Gamble.

They started by mixing soap formulas in beer pitchers labeled “Do Not Drink” and wound up creating Method, an irreverent, design-driven, environmentally minded company that outsourced manufacturing. The company grew to $34 million in revenue and 39 employees in 2005, and more than $100 million and 100 employees in 2012. Those numbers remain modest compared to those of Big Soap, but a walk down the cleaning aisle in almost any supermarket reveals not just Method’s reach (Ginger Yuzu dish soap, Pink Grapefruit hand wash) but its impact on competitors (Clorox Green Works).

“We showed up at the party with a very different proposition,” Mr. Ryan said. “We’re superproud that we’ve had an influence.”

That influence will continue, Mr. Ryan and Mr. Lowry suggest, even though Method was acquired for an undisclosed price in September by the Belgian company Ecover, creating what they claim is now the largest green cleaning company in the world, with revenue “north of $200 million.”

In a conversation that has been edited and condensed, we recently asked Mr. Ryan why he and Mr. Lowry chose to sell, how they identified the right suitor, and what will happen to the Method brand.

Q. Was selling the company always a primary goal?

A. When we started the company, we knew we had two choices. One was to grow organically, which a lot of businesses do, and you control the business and grow slowly and steadily. We fundamentally believed that we would not have success in this competitive space unless we went after it fast and aggressively. So we had to take outside capital. And when we took that outside capital — at some point, you have to give it back with a return.

Q. You make soap, you sell it, you make more soap, you sell more of it. Why couldn’t you grow without being acquired?

A. Two primary reasons. One is just economies of scale. In the early years, we lost money on every product we sold. We were competing against companies that not only have a 100-year head start but have just built incredible efficiencies. They own their own plants. When you walk in a grocery store and that bottle of dish soap sells for $1.99, we could not make it for $1.99 in the beginning. We needed capital to accelerate growth, to get our volume to a place where the business would be profitable. Two is that the cost of doing business in the mass channel is really expensive. When you sell in a grocery store, you have to pay an upfront fee called slotting charges. And that takes a fair amount of capital. So growing organically is possible, but it’s really, really tough.

Q. You’ve built a brand that seems to resonate with consumers. Are you concerned about their reaction to the sale?

A. It was something that was heavy in our minds for a lot of years. The typical script for a socially driven company like ours is you get acquired by a major strategic. So look at Honest Tea, acquired by Coke. Kashi by Kellogg. Burt’s Bees by Clorox. Even Mrs. Meyer’s, in our space, by SC Johnson. I always justified it by saying, “Well, if that happens, it’ll give us the chance to work from a bigger, global stage, and we’ll try to change those companies from the inside out.” And once we did this deal, I was just so thankful we never had to go down that path. We recognized we had a partner at the table with identical mission statements, identical values and a real long-term commitment. It was just an opportunity too good to pass up.

Q. Did you say no to other offers because you didn’t see that cultural fit?

A. We can’t name names, but we did have, over the years, conversations with those usual suspects. And the movie looked pretty similar — full integration, we go from being a company to being an operating unit within a larger organization. The culture, the team, “the Method Method” that we spent the last 10 years building would have been nonexistent within 12 months.

Q. Will the Method brand continue to exist?

A. Very much so. We’ll be building our own plant in North America. We’re turning on TV advertising for the first time in our history. We’re expanding more aggressively in Europe and Asia than we would have done otherwise. We’re creating a company with a long-term focus on the future. When you’re private equity-backed, it’s a much more short-term focus in how you invest and build the organization. The big thing that’s changing now, we’re a house of brands, which is Method and Ecover. And we have to set up a business where they coexist in a way that they don’t cannibalize each other and reach a broader audience collectively.

Q. Obviously, you’re in the honeymoon phase. How do you protect against something going wrong?

A. At the end of the day, it’s like a marriage — there is a leap of faith. And the way that you can protect yourself the most is just really trusting your instincts of who you’re jumping in bed with. It’s just like a job interview or any other relationship. If you’re getting to a point where you’re having to lean on a lot of legalities or other ways to try to protect yourself, it’s probably not the right relationship. It just comes back again to, are these people you trust, who share the same vision?

Q. While this was developing, how open were you with your employees?

A. You just can’t talk openly. It can do damage to the deal, but also, it’s a roller coaster, and you don’t want everyone riding the roller coaster with you. It’s incredibly distracting. There was a very small group that was in the know, and those were only the ones that were needed for due diligence. People knew we were looking and we were upfront about that, but they didn’t know to what extent, because we didn’t know to what extent. So when we did the announcement, there was initial shock, but over all it went well. And then for the next week, it was really challenging because what happened — what we were completely blindsided by — was how many people in their careers had been through a bad M.& A. transaction. There were a lot of bad movies that started being replayed. What I told everybody was, “Look, I’ve never been through a bad merger in my life, and I’m not about to start now.”

Q. Things have been tough in Europe. Any concerns about partnering with a European company and expanding there?

A. I like the idea of investing when something is at its lowest. [Laughs.] No, we have not had too many concerns about it. This business is firing on all cylinders. I was definitely, in the back of my head, concerned that things would get derailed by the European crisis, but who we’re dealing with is very long-term focused and they’re also very globally minded. Europe is a big part of their business, but they’re also expanding aggressively in Asia — we are as well — and North America.

Q. And everyone needs soap.

A. And everybody needs soap. It’s a dirty world out there.
