SpaceX launches to space station, but experiences problem in orbit

On an overcast morning, SpaceX's Falcon 9 rocket launched from Space Launch Complex 40 at Cape Canaveral Air Force Station and sped through the clouds Friday on its way to the International Space Station.

However, about 12 minutes into the NASA resupply mission, after the rocket had lifted its Dragon capsule packed with more than 1,200 pounds of cargo into orbit, there was an anomaly in the spacecraft.

"It appears that although it reached Earth orbit, Dragon is experiencing some type of problem right now," John Insprucker, Falcon 9 product director, told viewers on SpaceX's live webcast. "We'll have to learn the nature of what happened."

The live webcast was then shut down.

Elon Musk, SpaceX founder and chief executive, took to Twitter to describe the problem: "Issue with Dragon thruster pods. System inhibiting three of four from initializing. About to command inhibit override."

The company later issued a statement about the thrusters, which are crucial to the spacecraft successfully reaching the space station:

"One thruster pod is running. Two are preferred to take the next step which is to deploy the solar arrays. We are working to bring up the other two in order to plan the next series of burns to get to station."

The Hawthorne company's craft blasted off at 7:10 a.m. PST. The plan was that Dragon would reach and attach to the space station on Saturday, but it's unclear how the thruster issue will affect that.

There is a news conference slated for later in the day, when more information may be available.

SpaceX, formally known as Space Exploration Technologies Corp., has already performed successful NASA resupply missions to the space station. There was one official mission in October, and a demonstration mission took place in May.

Both of those missions also had problems.

In May, a problem with the Dragon's onboard sensors pushed back its capture by the station by about two hours later than planned.

In October, one of the nine engines on the massive Falcon 9 rocket experienced a problem and shut down shortly after launch. Because of the glitch, a satellite that the rocket was carrying didn't reach proper orbit, but the NASA resupply mission went on as planned and the Dragon capsule connected with the space station.

DNA science points to better treatment for acne

Ancient Egyptians were vexed by it, using sulfur to dry it out. Shakespeare wrote of its "bubukles, and whelks, and knobs, and flames o' fire."

Today, acne plagues us still. Doctors can cure some cancers and transplant vital organs like hearts, but they still have trouble getting rid of the pimples and splotches that plague 85% of us at some time in our lives — usually, when we're teenagers and particularly sensitive about they way we look.

But new research hints that there's hope for zapping zits in the future, thanks to advances in genetic research.

Using state-of-the-art DNA sequencing techniques to evaluate the bacteria lurking in the pores of 101 study volunteers' noses, scientists discovered a particular strain of Propionibacterium acnes bacteria that may be able to defend against other versions of P. acnes that pack a bigger breakout-causing punch.

As best as dermatologists can tell, zits occur when bacteria that reside in human skin, including P. acnes, feed on oils in the pores and prompt an immune response that results in red, sometimes pus-filled bumps. But the study subjects who had the newly discovered bacterial strain weren't suffering from whiteheads or blackheads, according to a report published Thursday in the Journal of Investigative Dermatology.

Someday, the realization that "not all P. acnes are created equal" might help dermatologists devise treatments that more precisely target bad strains while allowing beneficial ones to thrive, said Dr. Noah Craft, a dermatologist at the Los Angeles Biomedical Research Institute who conducted the study with colleagues from UCLA and Washington University in St. Louis.

Doctors might prescribe probiotic creams that deliver "good" P. acnes to the face the same way a daily serving of yogurt helps restore healthy bacteria in the digestive tract.

"There are healthy strains that we need on our skin," Craft said. "The idea that you'd use a nuclear bomb to kill everything — what we're currently doing with antibiotics and other treatments — just doesn't make sense."

The research is part of a broad effort backed by the National Institutes of Health to characterize the so-called human microbiome: the trillions of microbes that live in and on our bodies and evolve along with us, sometimes causing illness and often promoting good health.

Most of the microbiome attention so far has gone to studying species in the gut, said study leader Huiying Li, an assistant professor of molecular and medical pharmacology at UCLA's Geffen School of Medicine. But the NIH's Human Microbiome Project, which funds her research, also looks at microbial communities in the nasal passages, the mouth, the urogenital tract and the skin.

Li said she became interested in studying acne because the skin microbiome seemed particularly understudied.

The research team recruited 101 patients in their teens and 20s from dermatology clinics in Southern California. Among them, 49 had acne and 52 had "normal skin" and were not experiencing breakouts but had come to the clinics for other problems.

Doctors used adhesive pore strips to remove skin bacteria from patients' noses. The researchers then collected the waxy plugs — a combination of bacteria, oils, dead skin cells and other stuff — and used DNA to figure out which bacteria were present.

They found that the P. acnes species accounted for about 90% of the bacteria in pores, in both healthy patients and acne sufferers. Digging a little deeper into the DNA, they found that two particular strains appeared in about 20% of acne sufferers, while a third strain was found only in acne-free patients.

"Dogs are dogs, but a Chihuahua isn't a Great Dane," Craft said. "People with acne had pit bulls on their skin. Healthy people had poodles."

The team then sequenced the complete genomes — about 2.6 million base pairs apiece — of 66 of the P. acnes specimens to explore in more depth how the good and bad strains differed.

The two notable bad strains had genes, probably picked up from other bacteria or viruses, that are thought to change the shape of a microbe to make it more virulent. The researchers hypothesized that the foreign DNA, perhaps by sticking more effectively to human host tissues, may help trigger an inflammatory response in the skin: acne.

The good strain, on the other hand, contained an element known to work like an immune system in bacteria, Li said. Perhaps it allows this P. acne to fight off intruders and prevent pimples from forming.

Li said the researchers did not know why some people had the bad P. acnes strains and others did not, and whether genetics or environment played a bigger role.

Dr. Vincent Young, who conducts microbiome research at the University of Michigan Medical School but wasn't involved in the acne project, said advances in sequencing technology and analysis made the new study possible. In the past, he said, scientists wouldn't have tried to sequence dozens of genomes in a single species.

"They'd say, why waste the money?" he said. "Now you can do this in a couple of days."

Li and Craft — neither of whom suffered bad acne as teens — plan to keep up the work.

More research is needed to come up with super-targeted anti-microbial therapies, or to develop a probiotic cream for acne sufferers.

Craft continues collecting samples from patients' pores. He hopes to study whether twins share the same microbial profiles, how acne severity is reflected in bacteria populations, and how things change in a single patient over the course of a treatment regimen.

One of the study volunteers, 19-year-old UC Santa Cruz student Brandon Pritzker, said he would have loved to have treated his acne without affecting the rest of his body. When he took Accutane, he suffered back pain and mood shifts.

Now off the drug, Pritzker said he is at peace with his pimples. "I still have breakouts, but I figure I'm 19, that's the way it's going to be," he said.

But, he added, "it hindered my confidence at the time. Kids with clear skin are probably a little happier."

Donald Trump returns to the 'Apprentice' boardroom

NEW YORK (AP) — There is something Donald Trump says he doesn't know.

Trump has welcomed a reporter to his 26th-floor corner office in Trump Tower to talk about "All-Star Celebrity Apprentice." And here in person, this one-of-a-kind TV star, billionaire businessman, ubiquitous brand mogul and media maestro strikes a softer pose than he has typically practiced in his decades on public display.

Relaxed behind a broad desk whose mirror sheen is mostly hidden by stacks of paper that suggest work is actually done there, Trump is pleasant, even chummy, with a my-time-is-your-time easiness greeting his guest.

He even contradicts his status as a legendary know-it-all with this surprising admission: There's a corner of the universe he doesn't understand.

The ratings woes of NBC, which airs his show, are on Trump's mind at the moment, and as he hastens to voice confidence in the network's powers-that-be ("They will absolutely get it right"), he marvels at the mysteries of the entertainment world.

"If I buy a great piece of real estate and do the right building, I'm really gonna have a success," he says. "It may be MORE successful or LESS successful, but you can sort of predict how it's gonna do. But show business is like trial and error! It's amazing!"

He loves to recall the iffy prospects for "The Apprentice" when it debuted in January 2004. With show biz, he declares, "You NEVER know what's gonna happen."

Except, of course, when you do.

"I do have an instinct," he confides. "Oftentimes, I'll see shows go on and I'll say, 'That show will never make it,' and I'm always right. And I understand talent. Does anybody ask me? No. But if they did, I would be doing them a big service. I know what people want."

So maybe he does know it all. In any case, lots of people wanted "The Apprentice." In its first season, it averaged nearly 21 million viewers each week.

And it gave Trump a signature TV platform that clinched his image as corporate royalty. He presided in a mood-lit stagecraft boardroom where celebrity subjects addressed him as "Mr. Trump" and shrank at that dismissive flick of his wrist and dreaded catchphrase, "You're fired."

The two-hour premiere of "All-Star Celebrity Apprentice" (Sunday at 9 p.m. EST) starts by rallying its 14 veteran contenders in the even more evocative setting of the 2,000-year-old Egyptian Temple of Dendur at the Metropolitan Museum of Art.

There, grandly, Trump receives such returning players as Gary Busey, Stephen Baldwin, LaToya Jackson and reality mean queen Omarosa.

Soon, teammates are chosen by team leaders Bret Michaels and Trace Adkins. Their first assignment: concoct a winning recipe for meatballs, then sell more of them than the rival team.

This is the 13th edition of the "Apprentice" franchise, which has now slipped to less than one-third its original viewership, according to Nielsen Co. figures. But even an audience matching last season's 6.26 million viewers would be pleasant news for NBC, which has recently fallen to fifth place in prime time, behind even Spanish-language Univision.

"I could probably do another show when I don't enjoy 'The Apprentice' anymore," says the 66-year-old Trump, mulling his TV future. "I have been asked by virtually every network on television to do a show for them. But there's something to sticking with what you have: This is a good formula. It works."

Years before "The Apprentice," Trump had hit on a winning formula for himself: Supercharge his business success with relentless self-promotion, putting a human face — his! — on the capitalist system, and embedding his persona in a feedback loop of performance and fame.

Since then, he has ruled as America's larger-than-life tycoon and its patron saint of material success. Which raises the question: Does he play a souped-up version of himself for his audience as Donald Trump, a character bigger and broader than its real-life inspiration?

He laughs, flashing something like a you-got-me smile.

"Perhaps," he replies. "Not consciously. But perhaps I do. Perhaps I do."

It began as early as 1987, when his first book, "Trump: The Art of the Deal," became a huge best-seller.

And even without a regular showcase, he was no stranger to TV. For instance, in the span of just 10 days in May 1997, Trump not only was seen on his "Miss Universe Pageant" telecast on CBS, but also made sitcom cameo appearances as himself on NBC's "Suddenly Susan" and ABC's "Drew Carey Show."

Meanwhile, as a frequent talk-show guest then (as now), he publicized his projects and pushed his brand.

"I'll be on that show for 20 or 30 or 60 minutes, and it costs me nothing," he notes. "When you have an opportunity for promotion, take it! It's free."

No one has ever accused Trump of hiding his light under a bushel. But his promotional drive (or naked craving for attention) has taken him to extremes that conventional wisdom warns against: saying and doing things that might hurt your bottom line.

Item: Trump's noisy, even race-baiting challenge to President Barack Obama to prove his American citizenship. This crusade has earned Trump the title from one editorialist as "birther blowhard."

For an industrialist and entertainer, where's the profit in voicing political views that could tick off a segment of your market or your audience?

"It's a great question, and a hard question to answer, because you happen to be right," Trump begins. "The fact is, some people love me, and some people the-opposite-of-love me, because of what I do and because of what I say. But I'm a very truthful person. By speaking out, it's probably not a good thing for me personally, but I feel I have an obligation to do it."

But isn't he being divisive with some of his pronouncements?

"I think 'divisive' would be a fair word in some cases, not in all cases," he replies. "But I think 'truthful' is another word."

The publicity he got from his political activism reached a fever pitch during his months-long, media-blitzed flirtation with running for president that seemed conveniently to dovetail with the Spring 2011 season of his TV show.

That May, he announced he would not run. For some, it was the final scene of nothing more than political theatrics.

"They weren't," Trump says quietly. "I was very seriously considering running. It was a race that the Republicans should have won. I made a mistake in not running, because I think I would have won."

He says he has no designs on this year's race for mayor of New York. But his politicizing continues apace. In his Twitter feed, with 2 million followers, he continues to bash China and rant about Washington. He phones in to Fox News Channel's "Fox & Friends" each Monday morning to vent his spleen.

"I believe in speaking my mind," he says, "and I don't mind controversy, as you probably noticed. I think sometimes controversy is a good thing, not a bad thing."

Last summer saw the opening in Aberdeen, Scotland, of Trump International Golf Links after a bitter, yearslong fight waged by environmentalists and local residents against government leaders and, of course, Trump.

A man for whom it seems no publicity is bad publicity, Trump insists the controversy helped the project.

"If there wasn't controversy surrounding it, I don't think anybody would even know it exists," he says, laying out the alternative: "I could take an ad: 'Golf course opening.'"

Trump even seems to profit from the harsh attention focused on his hair.

"I get killed on my hair!" he says, with no trace of remorse. But he wants everyone to know, "It's not a wig!" Nor is it an elaborately engineered coif to hide a hairline in retreat, as many Trump-watchers imagine.

To prove it, Trump does a remarkable thing: He lifts the flaxen locks that flop above his forehead to reveal, plain as day, a normal hairline.

"I wash my hair, I comb it, I set it and I spray it," he says. "That's it. I could comb it back and I'd look OK. But I've combed it this way for my whole life. It's become almost a trademark. And I think NBC would be very unhappy if I combed it back, 'cause — you know what? — maybe I wouldn't get as high a rating."

Phys Ed: What Housework Has to Do With Waistlines

Phys Ed

Gretchen Reynolds on the science of fitness.

One reason so many American women are overweight may be that we are vacuuming and doing laundry less often, according to a new study that, while scrupulously even-handed, is likely to stir controversy and emotions.

The study, published this month in PLoS One, is a follow-up to an influential 2011 report which used data from the U.S. Bureau of Labor Statistics to determine that, during the past 50 years, most American workers began sitting down on the job. Physical activity at work, such as walking or lifting, almost vanished, according to the data, with workers now spending most of their time seated before a computer or talking on the phone. Consequently, the authors found, the average American worker was burning almost 150 fewer calories daily at work than his or her employed parents had, a change that had materially contributed to the rise in obesity during the same time frame, especially among men, the authors concluded.

But that study, while fascinating, was narrow, focusing only on people with formal jobs. It overlooked a large segment of the population, namely a lot of women.

“Fifty years ago, a majority of women did not work outside of the home,” said Edward Archer, a research fellow with the Arnold School of Public Health at the University of South Carolina in Columbia, and lead author of the new study.

So, in collaboration with many of the authors of the earlier study of occupational physical activity, Dr. Archer set out to find data about how women had once spent their hours at home and whether and how their patterns of movement had changed over the years.

He found the information he needed in the American Heritage Time Use Study, a remarkable archive of “time-use diaries” provided by thousands of women beginning in 1965. Because Dr. Archer wished to examine how women in a variety of circumstances spent their time around the house, he gathered diaries from both working and non-employed women, starting with those in 1965 and extending through 2010.

He and his colleagues then pulled data from the diaries about how many hours the women were spending in various activities, how many calories they likely were expending in each of those tasks, and how the activities and associated energy expenditures changed over the years.

As it turned out, their findings broadly echoed those of the occupational time-use study. Women, they found, once had been quite physically active around the house, spending, in 1965, an average of 25.7 hours a week cleaning, cooking and doing laundry. Those activities, whatever their social freight, required the expenditure of considerable energy. (The authors did not include child care time in their calculations, since the women’s diary entries related to child care were inconsistent and often overlapped those of other activities.) In general at that time, working women devoted somewhat fewer hours to housework, while those not employed outside the home spent more.

Forty-five years later, in 2010, things had changed dramatically. By then, the time-use diaries showed, women were spending an average of 13.3 hours per week on housework.

More striking, the diary entries showed, women at home were now spending far more hours sitting in front of a screen. In 1965, women typically had spent about eight hours a week sitting and watching television. (Home computers weren’t invented yet.)

By 2010, those hours had more than doubled, to 16.5 hours per week. In essence, women had exchanged time spent in active pursuits, like vacuuming, for time spent being sedentary.

In the process, they had also greatly reduced the number of calories that they typically expended during their hours at home. According to the authors’ calculations, American women not employed outside the home were burning about 360 fewer calories every day in 2010 than they had in 1965, with working women burning about 132 fewer calories at home each day in 2010 than in 1965.

“Those are large reductions in energy expenditure,” Dr. Archer said, and would result, over the years, in significant weight gain without reductions in caloric intake.

What his study suggests, Dr. Archer continued, is that “we need to start finding ways to incorporate movement back into” the hours spent at home.

This does not mean, he said, that women — or men — should be doing more housework. For one thing, the effort involved is such activities today is less than it once was. Using modern, gliding vacuum cleaners is less taxing than struggling with the clunky, heavy machines once available, and thank goodness for that.

Nor is more time spent helping around the house a guarantee of more activity, over all. A telling 2012 study of television viewing habits found that when men increased the number of hours they spent on housework, they also greatly increased the hours they spent sitting in front of the TV, presumably because it was there and beckoning.

Instead, Dr. Archer said, we should start consciously tracking what we do when we are at home and try to reduce the amount of time spent sitting. “Walk to the mailbox,” he said. Chop vegetables in the kitchen. Play ball with your, or a neighbor’s, dog. Chivvy your spouse into helping you fold sheets. “The data clearly shows,” Dr. Archer said, that even at home, we need to be in motion.

Freddie Mac: Mortgage rates ease, with 30-year fixed at 3.51%

By E. Scott Reckard

February 28, 2013, 8:32 a.m.

Mortgage rates eased a bit early this week, Freddie Mac said, with 30-year fixed loans available for solid borrowers at an average 3.51%, down from 3.56% last week.

The 15-year fixed loan edged down from an average 2.77% to 2.76%. Borrowers would have been dinged for an average 0.8% of the loan amount in upfront lender fees and discount points to obtain the rates, Freddie Mac said in its weekly report, issued Thursday.

Start rates for popular types of adjustable mortgages also fell slightly, according to Freddie Mac. The big housing finance company surveys lenders each week about the terms they are offering to borrowers who have good credit scores, 20% down payments or home equity, and the financial wherewithal to afford payments.

Quiz: How much do you know about mortgages?

The average fixed rate for a 30-year loan bottomed out late last year at a record low of 3.31% as calculated by Freddie Mac. It has since risen to the 3.5% range, compared to 3.9% last year at this time, 5% for all of 2009 and 6% for all of 2008.

This week’s decline was influenced by the February consumer price index, said Freddie Mac’s chief economist, Frank Nothaft.  The index held steady for the second month in a row, soothing concerns that inflation might set in and push rates higher.

Race for L.A. city controller heats up

A previously low-profile race for Los Angeles city controller has begun to heat up as opponents of City Councilman Dennis Zine accuse him of "double dipping" the city's payroll and question why he is considering lucrative tax breaks for a Warner Center developer.

Zine, who for 12 years has represented a district in the southeast San Fernando Valley, is the better known of the major candidates competing to replace outgoing Controller Wendy Greuel.

The others are Cary Brazeman, a marketing executive, and lawyer Ron Galperin. Zine has raised $766,000 for his campaign, more than double that of Galperin, the next-highest fundraiser, and has the backing of several of the city's powerful labor unions.

He also has been endorsed by Mayor Antonio Villaraigosa and several of his council colleagues. Galperin is backed by the Service Employees International Union, one the city's largest labor groups, and Brazeman is supported by retired Rep. Diane Watson and several neighborhood council representatives.

With the primary ballot less than a week away, Brazeman and Galperin have turned up the heat on Zine, hoping to push the race beyond the March 5 vote. If no one wins more than 50% of the ballots cast, the top two vote-getters will face a runoff in the May general election.

In a recent debate, Zine's opponents criticized him for receiving a $100,000 annual pension for his 33 years with the Los Angeles Police Department and a nearly $180,000 council salary. Brazeman and Galperin called it an example of "double dipping" that should be eliminated.

That brought a forceful response from Zine, who shot back that he gives a big portion of his police pension check to charities.

"I am so tired of hearing 'double dipping,' " he said. "I worked 33 years on the streets of Los Angeles. I have given over $300,000 to nonprofits that need it.... That's what's happened with that pension."

In the same debate, Brazeman accused Zine of cozying up to a Warner Center developer by pushing for tax breaks on a project that already has been approved. The nearly 30-acre Village at Westfield Topanga project would add 1 million square feet of new shops, restaurants, office space and a hotel to a faded commercial district on Topanga Canyon Boulevard.

"The councilman proposed to give developers at Warner Center tens of millions of dollars in tax breaks even though it's a highly successful project," he said. "He wants to give it away."

City records show that less than a month after the development was approved in February 2012, Zine asked the council for a study looking at possible "economic development incentives" that could be given to Westfield in return for speeding up street and landscaping enhancements to the project's exterior.

The motion's language notes that similar tax breaks have been awarded to large projects in the Hollywood and downtown areas, and that "similar public investment in the Valley has been lacking." Westfield is paying for the $200,000 study.

Zine defended his decision before the debate audience, saying if the study finds that the city will not benefit, no tax breaks will be awarded. "If there's nothing there, then they get nothing," Zine said.

The controller serves as a public watchdog over the city's $7.3-billion annual operation, auditing the general fund, 500 special fund accounts and the performance of city departments. Those audits often produce recommendations for reducing waste, fraud and abuse.

But the mayor and the council are not obligated to adopt those recommendations, and as a result the job is part accountant, part scolder in chief. All the candidates say they will use their elective position not only to perform audits but also to turn them into action.

Their challenge during the campaign has been explaining how they will do that.

Zine, 65, says his City Hall experience has taught him how to get things done by working with his colleagues. He won't be afraid to publicly criticize department managers, he said, but thinks collaboration works better than being combative.

"You can rant and rave and people won't work with you," he said. "Or you can sit down and talk it out, and you can accomplish things."

Galperin, 49, considers himself a policy wonk who relishes digging into the details to come up with ways to become more efficient with limited dollars and to find ways to raise revenue using the city's sprawling assets. For instance, the city owns two asphalt plants that could expand production and sell some of its material to raise money to fix potholes, he said.

He's served on two city commissions, including one that found millions of dollars in savings by detailing ways to be more efficient. Zine is positioning himself as a "tough guy for tough times," but the controller should be more than that, Galperin said.

"What we really need is some thoughtfulness and some smarts and some effectiveness," he said. "Just getting up there and saying we need to be tough is not going to accomplish what needs to be done."

Brazeman, 46, started his own marketing and public relations firm in West Los Angeles a decade ago and became active in city politics over his discontent with a development project near his home. He has pushed the council to change several initiatives over the last five years, including changes to the financing of the Farmers Field stadium proposal that will save taxpayer dollars, he said.

As controller, he would pick and choose his battles, and, Brazeman said, be "the right combination of constructive, abrasive and assertive."

Global Health: After Measles Success, Rwanda to Get Rubella Vaccine

Rwanda has been so successful at fighting measles that next month it will be the first country to get donor support to move to the next stage — fighting rubella too.

On March 11, it will hold a nationwide three-day vaccination campaign with a combined measles-rubella vaccine, hoping to reach nearly five million children up to age 14. It will then integrate the dual vaccine into its national health service.

Rwanda can do so “because they’ve done such a good job on measles,” said Christine McNab, a spokeswoman for the Measles and Rubella Initiative. M.R.I. helped pay for previous vaccination campaigns in the country and the GAVI Alliance is helping financing the upcoming one.

Rubella, also called German measles, causes a rash that is very similar to the measles rash, making it hard for health workers to tell the difference.

Rubella is generally mild, even in children, but in pregnant women, it can kill the fetus or cause serious birth defects, including blindness, deafness, mental retardation and chronic heart damage.

Ms. McNab said that Rwanda had proved that it can suppress measles and identify rubella, and it would benefit from the newer, more expensive vaccine.

The dual vaccine costs twice as much — 52 cents a dose at Unicef prices, compared with 24 cents for measles alone. (The MMR vaccine that American children get, which also contains a vaccine against mumps, costs Unicef $1.)

More than 90 percent of Rwandan children now are vaccinated twice against measles, and cases have been near zero since 2007.

The tiny country, which was convulsed by Hutu-Tutsi genocide in 1994, is now leading the way in Africa in delivering medical care to its citizens, Ms. McNab said. Three years ago, it was the first African country to introduce shots against human papilloma virus, or HPV, which causes cervical cancer.

In wealthy countries, measles kills a small number of children — usually those whose parents decline vaccination. But in poor countries, measles is a major killer of malnourished infants. Around the world, the initiative estimates, about 158,000 children die of it each year, or about 430 a day.

Every year, an estimated 112,000 children, mostly in Africa, South Asia and the Pacific islands, are born with handicaps caused by their mothers’ rubella infection.

Thanks in part to the initiative — which until last year was known just as the Measles Initiative — measles deaths among children have declined 71 percent since 2000. The initiative is a partnership of many health agencies, vaccine companies, donors and others, but is led by the American Red Cross, the United Nations Foundation, the Centers for Disease Control and Prevention, Unicef and the World Health Organization.

Correction: February 27, 2013

An earlier version of this article misstated the source of the financing for the upcoming vaccination campaign in Rwanda. It is being financed by the GAVI Alliance, not the Measles and Rubella Initiative.

Pending home sales rise in January, industry group reports

Pending home sales rose in January in every U.S. region except the West, according to new data.

The National Assn. of Realtors said that its index of pending sales — based on the number of home purchase contracts signed — rose 4.5% in January from the previous month and 9.5% from January 2012.

The index, at 105.9, is at it hits highest reading since April 2010, the month a popular tax credit for buyers was driving the market up.

 “Favorable affordability conditions and job growth have unleashed a pent-up demand,” Lawrence Yun, chief economist for the group, said in a news release.

The group expects higher home sales in the short term but sales growth will be muted because there are not enough homes available for sale, Yun said.

An index level of 100 is equal to the average level of contract activity during 2001, which was the first year to be studied and also considered historically a healthy year of sales volume.

Month over month, pending sales were up 8.2% in the Northeast, 4.5% in the Midwest and 5.9% in the South. They were essentially flat, up just 0.1%, in the West, according to the index data.

Gaza militants break cease-fire with rocket attack into Israel

JERUSALEM -- Palestinian unrest spread Tuesday to the Gaza Strip, where militants fired a rocket into southern Israel, shattering one of the longest periods of quiet along that border in recent memory.

It was the first rocket fired since the signing of a November cease-fire agreement between Israel and the Palestinian militant group Hamas, ending their eight-day clash.

The morning attack came as Palestinians in the West Bank protest the death of 30-year-old Arafat Jaradat, a gas station attendant who died suddenly in Israeli custody after being arrested for throwing rocks at an Israeli settler.

Palestinians claim Jaradat was tortured to death. Israelis say the exact cause of his Feb. 23 death has not yet been determined.

The Grad rocket fired early Tuesday landed in an open area near the Israeli city of Ashkelon, causing no damage or injuries.
