Google’s fourth quarter results shine after ad rate decline slows

SAN FRANCISCO (Reuters) – Revenue from Google Inc’s core Internet business outpaced many analysts’ expectations during the crucial holiday quarter and advertising rates fell less than in previous periods, pushing its shares up more than 4 percent.

The world’s largest Internet search company introduced new product listings during the fourth quarter – typically its strongest – and also benefited from business growth in international markets, analysts said.

Excluding traffic-acquisition costs, the business generated net revenue of $ 9.83 billion, up from $ 8.13 billion a year earlier, Google reported on Tuesday. That surpassed a $ 9.6 billion average forecast from six analysts polled by Reuters.

“Business looked really strong, especially from a profitability perspective. They really grew their margins in the core business,” said Sameet Sinha, an analyst with B. Riley Caris. “Most of that strength seems to be coming from international markets which grew revenues quite substantially: up 23 percent year over year, versus the 15 percent growth in the third quarter.”

Average cost-per-click, a critical metric that denotes the price advertisers pay Google, declined 6 percent from a year ago, the fifth consecutive quarter of decline.

Google executives told analysts on a conference call that the company had focused on improving the metric – shoring up margins – while lowering the overall growth rate of paid clicks in the holiday quarter.

“Click prices are still declining, but it’s better than expected,” said BGC Partners analyst Colin Gillis.

MOTOROLA MOBILITY “STILL LOSING MONEY”

Consolidated net income in the fourth quarter was $ 2.89 billion or $ 8.62 per share, compared with $ 2.71 billion, or $ 8.22 per share, in the year-ago period when Google had not yet acquired Motorola.

Excluding certain items, Google said it earned $ 10.65 per share in the fourth quarter.

“The core business is a great business and the fourth-quarter is always a time for Google to shine. However, Motorola is still losing money and click rates still declined. They only declined 6 percent, but go back four or five quarters and click prices were improving. So mobile is still pressuring click prices,” Gillis said.

The company posted consolidated revenue – which includes its Motorola Mobility mobile phone business but not the television set-top box business it recently agreed to sell – of $ 14.42 billion on Tuesday.

Motorola Mobility had an operating loss of $ 353 million during the quarter.

Shares of Google were up roughly 4.5 percent at $ 734.46 in after-hours trading on Tuesday.

Djokovic getting the hang of winning in Australia

MELBOURNE, Australia (AP) — Novak Djokovic is really starting to get the hang of how to handle himself at the Australian Open.

An expression often used Down Under — "Keep your shirt on" — is designed to discourage anyone from becoming unnecessarily overexcited.

Djokovic took it literally after his 6-1, 4-6, 6-1, 6-4 win Tuesday night over fifth-seeded Tomas Berdych, advancing to the semifinals at an 11th consecutive Grand Slam tournament.

The 2-hour, 31-minute victory took exactly half the time of his five-set, fourth-round win two nights previously against Stanislas Wawrinka. In the early hours of Monday morning, Djokovic ripped his sweat-drenched shirt off and flexed his muscles, mimicking his victory celebration after the 5:53 victory over Rafael Nadal in the 2012 Australian Open final.

That was acceptable at the time to the Rod Laver Arena crowd, which was still abuzz at 1:40 a.m. following five sets of high-level tennis.

After the Berdych match, however, he realized there was no need to raise the roof. Djokovic calmly pumped his fist once and walked to the net; he later joked about the ice baths he'd taken in between matches on the advice of local hero Lleyton Hewitt.

"It was a great performance. I was hoping to have a shorter match ... just not to go over 5 hours," Djokovic said, in a comparatively subdued mood after a considerably more routine victory. "It's always going to be tough against Tomas; he's an established player. He has a big game, big serve. He can compete against anyone on any surface."

In the semifinals, Djokovic will meet No. 4-seeded David Ferrer.

Ferrer survived a quarterfinal battle with fellow Spaniard Nicolas Almagro. Almagro had three chances to serve for the match, but Ferrer broke each time.

A usually mild-mannered pro, Ferrer showed his aggression at times when he threatened to spike his racket and even smashed his water bottle in the changeover after he'd dropped serve in a frustrating fourth set that featured eight breaks of serve.

He'd never lost to Almagro in 12 previous meetings and, as the No. 1 Spaniard in the draw in the absence of 11-time major winner Rafael Nadal, felt a responsibility to reach the semis.

"It was (a) miracle I won this match," Ferrer said of his comeback 4-6, 4-6, 7-5, 7-6 (4), 6-2 win. "I tried to fight every point; that's my game. I always fight."

Ferrer survived once in the third set and twice in the fourth when Almagro was serving for the match, but held his nerve and finally advanced to his third semifinal in the last four Grand Slam events.

"In the important moments, I played more consistent in my game," Ferrer said. "Of course, in the next round, the semifinals, I need to play my best tennis, better than today."

Djokovic acknowledged Ferrer's work ethic, saying the 30-year-old Spaniard was "one of the most respected guys on the tour because he never gives up."

"He plays every single match of his career with 100 percent," Djokovic said.

"I'm expecting a long one," he added.

Ferrer has never been past a major semifinal.

There are only three men left in the draw who have won Grand Slam titles — Djokovic has won five, including the last two in Australia. He's aiming to be the first man in the Open era to win three consecutive Australian titles.

The other two are in action Wednesday, with 17-time Grand Slam winner Roger Federer against 2008 Australian finalist Jo-Wilfried Tsonga of France. Andy Murray, who broke the 76-year drought for British men at the major tournaments by winning the U.S. Open last year, will play Jeremy Chardy of France.

On the women's side, defending champion Victoria Azarenka faces Svetlana Kuznetsova, who has won the U.S. Open and the French Open, and 15-time major winner Serena Williams is against 19-year-old American Sloane Stephens, who is playing her first quarterfinal at a Grand Slam.

Maria Sharapova completed a career Grand Slam last year by winning the French Open, a few months after losing the Australian Open final to Azarenka. After her 6-2, 6-2 quarterfinal win over Ekatrina Makarova on Tuesday, she has conceded only nine games in five matches — a record in Australia.

"To be honest, those are not the stats you want to be known for," Sharapova said.

After opening with a pair of 6-0, 6-0 wins, Sharapova thrashed seven-time major winner Venus Williams 6-1, 6-3 in the third round and Belgian Kristen Flipkens 6-0, 6-1 in the fourth.

Li Na has reached the semifinals in three of the last four years at Melbourne Park after beating Agnieszka Radwanska 7-5, 6-3. The 30-year-old Chinese player lost the 2011 final in Australia to Kim Clijsters, then won her breakthrough Grand Slam at the French Open a few months later. She hasn't been back to a major final since.

Djokovic won his first major title in Australia in 2008, then didn't make another final in his next 11 Grand Slam events. He's won four since then and is the top-ranked man in tennis, crediting the lessons from his experiences back then.

"At the start of my career, I went through a lot of different kinds of challenges physically, mentally," he said. "Everybody makes mistakes. I was aware of the fact that I need to improve because I wasn't feeling well, especially in the heat. I had lots of health issues.

"I don't want to go through it again. I am aware of the importance of an everyday practice and recovery basis. So as long as it's like that, I think I'll be all right."

Medicaid Patients Could Face Higher Fees Under a Proposed Federal Policy

WASHINGTON — Millions of low-income people could be required to pay more for health care under a proposed federal policy that would give states more freedom to impose co-payments and other charges on Medicaid patients.

Hoping to persuade states to expand Medicaid, the Obama administration said state Medicaid officials could charge higher co-payments and premiums for doctors’ services, prescription drugs and certain types of hospital care, including the “nonemergency use” of emergency rooms. State officials have long asked for more leeway to impose such charges.

The 2010 health care law extended Medicaid to many childless adults and others who were previously ineligible. The Supreme Court said the expansion of Medicaid was an option for states, not a requirement as Congress had intended. The administration has been trying to persuade states to take the option, emphasizing that they can reconfigure Medicaid to hold down their costs and “promote the most effective use of services.”

In the proposed rule published Tuesday in the Federal Register, the administration said it was simplifying a complex, confusing array of standards that limit states’ ability to charge Medicaid beneficiaries. Under the proposal, a family of three with annual income of $30,000 could be required to pay $1,500 in premiums and co-payments.

As if to emphasize the latitude given to states, the administration used this heading for part of the new rule: “Higher Cost Sharing Permitted for Individuals With Incomes Above 100 Percent of the Federal Poverty Level” (that is, $19,090 for a family of three).

Barbara K. Tomar, director of federal affairs at the American College of Emergency Physicians, said the administration had not adequately defined the “nonemergency services” for which low-income people could be required to pay. In many cases, she said, patients legitimately believe they need emergency care, but the final diagnosis does not bear that out.

“This is just a way to reduce payments to physicians and hospitals” from the government, Ms. Tomar said.

With patients paying more, the federal government and states would pay less than they otherwise would. Medicaid covers 60 million people, and at least 11 million more are expected to qualify under the 2010 law. The federal government pays more than half of Medicaid costs and will pay a much larger share for those who become eligible under the law.

In the proposed rule, the administration said it had discovered several potential problems in its efforts to carry out the law.

First, it said, it has not found a reliable, comprehensive and up-to-date source of information about whether people have employer-sponsored health insurance. The government needs such information to decide whether low- and middle-income people can obtain federal subsidies for private insurance.

The subsidies can be used to buy coverage in competitive marketplaces known as insurance exchanges. Under the law, people can start enrolling in October for coverage that starts in January 2014, when most Americans will be required to have health insurance. People who have access to affordable coverage from employers will generally be ineligible for subsidies.

In applying for subsidies, people must report any employer-sponsored insurance they have. But the administration said it could be difficult to verify this information because the main sources of data reflect only “whether an individual is employed and with which employer, and not whether the employer provides health insurance.”

Since passage of the health care law, the administration has often said that people seeking insurance would use a single streamlined application for Medicaid and the subsidies for private coverage. Moreover, the state Medicaid agency and the exchange are supposed to share data and issue a “combined eligibility notice” for all types of assistance.

But the administration said this requirement would be delayed to Jan. 1, 2015, because more time was needed to establish electronic links between Medicaid and the exchanges.

Leonardo D. Cuello, who represents Medicaid beneficiaries as a lawyer at the National Health Law Program, expressed concern.

“Under the proposed rule,” Mr. Cuello said, “many people will be funneled into health insurance exchanges even though they have special needs that are better met in Medicaid. And if you asked the right questions, you would find out that they are eligible for Medicaid.”

The federal government will have the primary responsibility for running exchanges in more than half the states. About 20 states are expected to expand Medicaid; governors in other states are opposed or uncommitted.

The proposed rule allows hospitals to decide, “on the basis of preliminary information,” whether a person is eligible for Medicaid. States must provide immediate temporary coverage to people who appear eligible.

Kenneth E. Raske, president of the Greater New York Hospital Association, said this could be a boon to low-income people. “Currently,” he said, “only children and pregnant women are presumed eligible for inpatient admissions under Medicaid in New York.”

The public has until Feb. 13 to comment on the proposed rule. Comments can be submitted at www.regulations.gov.

More Questions Are Raised in Boeing 787 Battery Fires

Investigators in the United States and Japan indicated on Tuesday that many questions remained unanswered in their search for the cause of two incidents in which lithium-ion batteries burned on Boeing 787 aircraft.

In Washington, the National Transportation Safety Board said on Sunday that the battery on a Japanese plane that suffered a fire at a gate at Logan airport in Boston on Jan. 7 had not been charged beyond its maximum design voltage, 32 volts.

But on Tuesday, Kelly Nantel, a spokeswoman for the board, said that while the flight recorder had not indicated excessive voltage, that did not eliminate the possibility of charging problems. Experts in lithium-ion batteries said the batteries may have been charged too quickly, a possibility cited last week by Hideyo Kosugi, an investigator general for aircraft accidents in Japan.

In Japan, officials said on Wednesday that air safety investigators had asked the national space agency, JAXA, to examine the battery from the Air Nippon Airlines 787 that made the emergency landing last week. JAXA will conduct a scan of the battery. Experts from the company that built it, GS Yuasa, intend to take it apart afterward and examine each cell.

Ms. Nantel said her agency had given information to the Japanese on the progress in examining the Logan battery. It underwent CT scans and X-rays. “We’re sharing our experience,” she said. “They’re several days behind us.”

Senate aides in Washington are organizing a hearing to examine how the plane was certified by the Federal Aviation Administration. The administrator of the F.A.A. and the secretary of transportation, are expected to speak on Wednesday about progress of the inquiry.

The safety board is leading the American part of the investigation, but the F.A.A. will decide what fix is required and whether to let the plane return to service.

Euro Official, in New Role, Aims to Mend Rift Over Austerity

BRUSSELS — Jeroen Dijsselbloem, the newly elected president of the group of ministers overseeing the euro, said on Monday he wanted to heal the rift over austerity policies that had bred mistrust between southern and northern nations using the currency.

Mr. Dijsselbloem, 46, the Dutch finance minister, also said he wanted to improve the stature of the group, and the image of the currency, after three years of near-constant crises and moments of deep division.

The only opposition during the vote to elect Mr. Dijsselbloem, held late Monday, came from Luis de Guindos, the Spanish economy minister. Mr. Dijsselbloem, whose term lasts two-and-a-half years, told a news conference that Mr. de Guindos offered no explanation for the decision but he said the Spanish move should not “lead to dramatic consequences.”

Spain is among the countries in southern Europe to have been hardest hit by the austerity policies that northern nations like Finland, Germany and the Netherlands have insisted on as an important solution to the euro crisis.

Spanish officials have been irritated by the preponderance of representatives from so-called Triple-A rated countries, which pay less to borrow than countries with weaker ratings, in top economy jobs in Europe. Spanish officials were particularly angered by a decision last year not to select a Spaniard for a seat on the executive board of the European Central Bank.

In a sign of his concern about fractures in the euro zone, Mr. Dijsselbloem pledged to do what he could to assuage those tensions in his new role coordinating meetings of finance ministers when they make decisions like giving political approval for bailouts and pressing governments to shore up their finances.

“If we are going to approach the euro zone and the euro area as a zone with a harsh line in the middle between Triple-A and non-Triple-A, between the north and the south, there’s no way we’re going to move forward and no way are we going to reach decisions that are so much needed,” Mr. Dijsselbloem said. “So that will definitely not be my approach,” he said.

The French also had concerns about putting a representative from the Netherlands in charge of the group and they insisted that Mr. Dijsselbloem explain to the other 16 finance ministers in the Eurogroup how he intended to carry out the job before the vote was held.

But the French finance minister, Pierre Moscovici, told a news conference that he was satisfied with the outcome because he expected Mr. Dijsselbloem to act fairly. “It’s a Dutchman who is president; it’s not a Dutch presidency,” Mr. Moscovici said.

Mr. Moscovici said he expected other top finance jobs, including the job of overseeing a new banking supervisor based at the European Central Bank, would be allocated to French candidates. But he insisted that was not a reason he voted in favor of Mr. Dijsselbloem’s appointment.

Allies of Mr. Dijsselbloem also have sought to ease fears that his presidency would be divisive, saying that his membership of a left-leaning social democratic party could help him mediate between nations like France with different views to many in the Netherlands on how to stabilize the euro.

“Jeroen should be able, within financial sound limits, to bridge the debate between those who criticize budget cuts and those who emphasize the need to enforce the treaties on budgetary controls,” Thijs Berman, the leader of the Dutch social democrats in the European Parliament, said Monday.

Another goal of Mr. Dijsselbloem is to reform the way the group operates to cut down on the need for emergency sessions and all-night meetings.

In a letter sent to ministers on the eve of the vote, Mr. Dijsselbloem suggested that the group hash out their views in “discussion papers” to make decision-making smoother. He also said he wanted a “clear mandate” to represent the Eurogroup “on an international stage,” including at Group of 20 meetings and in international financial institutions.

“Our focus needs to shift from crisis management to delivering and implementing sound medium-term policies,” Mr. Dijsselbloem said in his letter to ministers.

Sony to sell new Xperia tablet in Japan: Nikkei

(Reuters) – Sony Corp’s Sony Mobile Communications Inc said it will sell the new version of its Xperia tablet in Japan this spring, the Nikkei reported, citing Kyodo News.

The Xperia Tablet Z, whose price has not been announced, has a 10.1-inch display, is 6.9 mm thin and weighs 495 grams, according to the company’s website.

Rival Google Inc’s Nexus 10 tablet is 8.9 mm thick, while Apple Inc’s iPad mini measures 7.9 mm.

Sony halted sales of Xperia in October, a month after launch, after discovering gaps between the screen and the case that made some of the machines susceptible to water damage.

The Nikkei reported on Sunday that Japanese smartphone makers seem to be regaining some market share they lost to companies like Apple and Samsung Electronics Co.

Jim, John Harbaugh ready for rematch at Super Bowl

SANTA CLARA, Calif. (AP) — Jim and John Harbaugh have exchanged a handful of text messages, and plan to leave it at that. No phone conversations necessary while the season's still going. No time for pleasantries, even for the friendly siblings.

There is work to be done to prepare for the Super Bowl, prepare for each other, prepare for a history-making day already being widely hyped as "Harbowl" or "Superbaugh" depending which nickname you prefer.

"It doesn't matter who the coach is, what relationship you have with the person on the other side," 49ers coach Jim Harbaugh said so matter-of-factly Monday afternoon.

Their parents sure aren't picking sides for the Feb. 3 matchup in New Orleans.

These days, the Harbaughs' longtime coaching father, Jack, stays away from game-planning chatter or strategy sessions with his Super Bowl-bound coaching sons. Baltimore's John Harbaugh and little brother Jim have been doing this long enough now to no longer need dad's input.

Yet, they still regularly seek it. And, their father does offer one basic mantra: "Get ahead, stay ahead."

"Probably the greatest advice that I've ever been given and the only advice that I've ever found to be true in all of coaching, I think we mentioned it to both John and Jim ... the coaching advice is, 'Get ahead, stay ahead,'" Jack Harbaugh said.

"If I'm called upon, I'll repeat that same message."

His boys still call home regularly to check in with the man who turned both on to the coaching profession years ago, and the mother who has handled everything behind the scenes for decades in a highly competitive, sports-crazed family — with all the routine sports clichés to show for it.

The Harbaugh brothers will become the first siblings to square off from opposite sidelines when their teams play for the NFL championship at the Superdome.

Not that they're too keen on playing up the storyline that has no chance of going away as hard as they try.

"Well, I think it's a blessing and a curse," Jim Harbaugh said Monday. "A blessing because that is my brother's team. And, also, personally I played for the Ravens. Great respect for their organization. ... The curse part would be the talk of two brothers playing in the Super Bowl and what that takes away from the players that are in the game. Every moment that you're talking about myself or John, that's less time that the players are going to be talked about."

Both men love history, just not the kind with them making it.

"I like reading a lot of history ... I guess it's pretty neat," John Harbaugh offered Monday. "But is it really going to be written about? It's not exactly like Churchill and Roosevelt or anything. It's pretty cool, but that's as far as it goes."

Nice try, guys.

John watched the end of Jim's game from the field in Foxborough, Mass., as Baltimore warmed up for the AFC championship game. Jim called his sister's family from the team plane before takeoff after a win at Atlanta and asked how his big brother's team was doing against New England.

The improbable Super Bowl features a set of brothers known around the NFL as fierce competitors unafraid to make a bold move during the season. Unafraid to upset anyone who stands in their way.

In fact, each one made a major change midseason to get this far — John fired his offensive coordinator, while Jim boosted his offense with a quarterback switch from Alex Smith to Colin Kaepernick.

Leading up to Sunday's games, parents Jack and Jackie said they would wait to decide whether to travel to New Orleans if both teams advanced or stick to what has been working so well — watching from the comfort of their couch in Mequon, Wis.

"We enjoy it very much. We get down in our basement, turn on the television and just have a fantastic day watching outstanding football," Jack said last week. "We share our misery with no one but ourselves. Not only the misery, but the ups and downs, the ins and outs of an outstanding professional game."

And, no, the Harbaughs weren't looking ahead to a potential big trip to the Big Easy.

Jack insists his wife is quick to pull out that old sports cliche: "It's one game at a time. I think it's very appropriate," he said.

Jim figures they won't possibly miss this history-making game.

"I think they'll be there," he said with a smile.

The brothers, separated in age by 15 months, have taken different paths to football's biggest stage — years after their intense games of knee football at the family home. They tried to beat each other at cards, or whatever other game it was at the time. Sometimes, they tried to beat each other up. Sister, Joani Crean, often got in on the fun, too.

The 49-year-old Jim never reached a Super Bowl, falling a last-gasp pass short during a 15-year NFL career as a quarterback. The 50-year-old John never played in the NFL.

Still, both will tell you, "Who's got it better than us? No-body!" — one catchphrase they got from their dad.

"We can't put into words what it means to see John and Jim achieve this incredible milestone," their brother-in-law, Indiana basketball coach Tom Crean, said on Twitter. "We talked to Jim (before) his team plane left. All he wanted to know was how was John doing? How were they playing? One incredible family who puts the care, well-being and love for each other at the forefront like most families do. Again, we are very proud of them. Going to be exciting to watch it unfold."

John worked his way up from the bottom of the coaching ranks, while Jim was the star college quarterback at Michigan, a first-round draft pick and eventual Pro Bowler who made coaching his career once he retired.

John already has the one-up, while Jim's team is the early favorite. John's Ravens beat the 49ers 16-6 on Thanksgiving night 2011, in Jim's rookie season as an NFL coach — though both know that means nothing now.

"I just want everybody to know, that was a four-day deal and every story has been told," John said. "We're not that interesting. There's nothing more to learn. The tape across the middle of the room story, OK, you got it? It's OK. It was just like any other family, really. I really hope the focus is not so much on that. We get it, it's really cool and it's exciting and all that."

Said Jim, "Completely new business."

In spite of his efforts to avoid the topic, Jim did take the opportunity to express how proud he is of John.

"He's a great football coach, a real grasp of all phases — offense, defense, special teams. I think he could coordinate at least two of those phases and do it as well as anyone in the league," Jim said. "I've got half the amount of coaching experience he does. Again, it's not about us. I keep coming back to that. I'm really proud of my brother. I love him. That's the blessing part, that this is happening to him."

And, fittingly for the big brother, John feels the exact same way.

The Week: A Roundup of This Week’s Science News

“Science,” a colleague once said at a meeting, “is a mighty enterprise, which is really rather quite topical.” He was so right: as we continue to enhance our coverage of the scientific world, we always aim to keep the latest news front and center.

His observation seemed like a nice way to introduce this column, which will highlight the week’s developments in health and science news and glance at what’s ahead. This past week, for instance, the mighty enterprise of science addressed itself to such newsy topics as the flu (there’s still time to get vaccinated!), and mental illness and gun control.

In addition to the big-headline stories that invite wisdom from scientists, each week there is a drumbeat of purely scientific and medical news that emerges from academic journals, fieldwork and elsewhere. These developments, from the quirky to the abstruse, often make their way into the daily news cycle, depending on the strength of the research behind them. (Well, that’s how we judge them, anyway.)

Many discoveries are hard to unravel. “In a way, science is antithetical to everything that has to do with a newspaper,” the same colleague observed. “You couldn’t imagine anything less consumer-friendly.”

Let’s aim to fix that. Below, a selection of the week’s stories.

DEVELOPMENTS

Health

Strange, but Effective

People with a bacterial infection called Clostridium difficile — which kills 14,000 Americans a year — have a startling cure: a transplant of someone else’s feces into their digestive system, which introduces good bacteria that the gut needs to fight off the bad. For some people, antibiotics don’t fix this problem, but an infusion of diluted stool from a healthy person seems to do the trick.

Genetics

Dig We Must

Hillery Metz and Hopi Hoekstra/Harvard University

Evolutionary biologists at Harvard took a tiny species of deer mice, known for building elaborate burrows with long tunnels, and bred it with another species of deer mice, which builds short-tunneled burrows. Comparing the DNA of the original mice with their offspring, the biologists pinpointed four regions of genetic code that help tell the mice what kind of burrow to construct.

Aerospace

Launch, Then Inflate

Uncredited/Bigelow Aerospace, via Associated Press

NASA signed a contract for an inflatable space habitat — roughly pineapple-shaped, with walls of floppy cloth — that will ideally be appended to the International Space Station in 2015. NASA aims to use the pod to test inflatable technology in space, but the company that builds these things, Bigelow Aerospace, has bigger ambitions: think of a 12-person apartment and laboratory in the sky, with two months’ rent at north of $26 million.

Biology

What’s Green and Flies?

Jodi Rowley/Australian Museum

National Geographic reported on an Australian researcher working in Vietnam who discovered a great-looking new species of flying frog. Described as having flappy forearms (the better for gliding), the three-and-a-half-inch-long frog likes to “parachute” from tree to tree, Jodi Rowley, an amphibian biologist at the Australian Museum in Sydney, told the magazine. She named it Helen’s Flying Frog, for her mother.

Privacy

That’s Joe’s DNA!

People who volunteer their genetic information for the betterment of science — and are assured anonymity — may find that their privacy is not a slam dunk. A researcher who set out to crack the identities of a few men whose genomes appeared in a public database was able to do so using genealogical Web sites (where people upload parts of their genomes to try to find relatives) as well as some simple search tools. He was trying to test the database’s security, but even he did not expect it to be so easy.

Genetics

An On/Off Switch for Disease

Geneticists have long puzzled over what it is that activates a disease in one person but not in another — even in identical twins. Now researchers from Johns Hopkins and the Karolinska Institute in Sweden who studied people with rheumatoid arthritis have identified a pattern of chemical tags that tell genes whether to turn on or not. In rheumatoid arthritis, the immune system attacks the body, and it is thought the tags enable the attack.

Planetary Science

That Red Planet

Everybody loves Mars, and we’re all secretly hoping that NASA’s plucky little rover finds evidence of life there. Meanwhile, a separate NASA craft — the Mars Reconnaissance Orbiter, which has been looping the planet since 2006 — took some pictures of a huge crater that looks as if it once held a lake fed by groundwater. It is too soon to say if the lake held living things, but NASA’s news release did include the happy phrase “clues to subsurface habitability.”

COMING UP

Animal Testing

Retiring Chimps

Emily Wabitsch/European Pressphoto Agency

A lot of people have strong feelings about the use of chimpanzees in biomedical and behavioral experiments, and the National Institutes of Health has been listening. On Tuesday, the agency is to release its recommendations for curtailing chimp research in a big way. This will be but a single step in a long process and it will apply only to the chimps the agency owns, but it may well stir big reactions from many constituencies.

Employers’ Social Media Policies Come Under Regulatory Scrutiny

As Facebook and Twitter become as central to workplace conversation as the company cafeteria, federal regulators are ordering employers to scale back policies that limit what workers can say online.

Employers often seek to discourage comments that paint them in a negative light. Don’t discuss company matters publicly, a typical social media policy will say, and don’t disparage managers, co-workers or the company itself. Violations can be a firing offense.

But in a series of recent rulings and advisories, labor regulators have declared many such blanket restrictions illegal. The National Labor Relations Board says workers have a right to discuss work conditions freely and without fear of retribution, whether the discussion takes place at the office or on Facebook.

In addition to ordering the reinstatement of various workers fired for their posts on social networks, the agency has pushed companies nationwide, including giants like General Motors, Target and Costco, to rewrite their social media rules.

“Many view social media as the new water cooler,” said Mark G. Pearce, the board’s chairman, noting that federal law has long protected the right of employees to discuss work-related matters. “All we’re doing is applying traditional rules to a new technology.”

The decisions come amid a broader debate over what constitutes appropriate discussion on Facebook and other social networks. Schools and universities are wrestling with online bullying and student disclosures about drug use. Governments worry about what police officers and teachers say and do online on their own time. Even corporate chieftains are finding that their online comments can run afoul of securities regulators.

The labor board’s rulings, which apply to virtually all private sector employers, generally tell companies that it is illegal to adopt broad social media policies — like bans on “disrespectful” comments or posts that criticize the employer — if those policies discourage workers from exercising their right to communicate with one another with the aim of improving wages, benefits or working conditions.

But the agency has also found that it is O.K. for employers to act against a lone worker ranting on the Internet.

Several cases illustrate the differing standards.

At Hispanics United of Buffalo, a nonprofit social services provider in upstate New York, a caseworker threatened to complain to the boss that others were not working hard enough. Another worker, Mariana Cole-Rivera, posted a Facebook message asking, “My fellow co-workers, how do you feel?”

Several of her colleagues posted angry, sometimes expletive-laden, responses. “Try doing my job. I have five programs,” wrote one. “What the hell, we don’t have a life as is,” wrote another.

Hispanics United fired Ms. Cole-Rivera and four other caseworkers who responded to her, saying they had violated the company’s harassment policies by going after the caseworker who complained.

In a 3-to-1 decision last month, the labor board concluded that the caseworkers had been unlawfully terminated. It found that the posts in 2010 were the type of “concerted activity” for “mutual aid” that is expressly protected by the National Labor Relations Act.

“The board’s decision felt like vindication,” said Ms. Cole-Rivera, who has since found another social work job.

The N.L.R.B. had far less sympathy for a police reporter at The Arizona Daily Star.

Frustrated by a lack of news, the reporter posted several Twitter comments. One said, “What?!?!?! No overnight homicide. ... You’re slacking, Tucson.” Another began, “You stay homicidal, Tucson.”

The newspaper fired the reporter, and board officials found the dismissal legal, saying the posts were offensive, not concerted activity and not about working conditions.

The agency also affirmed the firing of a bartender in Illinois. Unhappy about not receiving a raise for five years, the bartender posted on Facebook, calling his customers “rednecks” and saying he hoped they choked on glass as they drove home drunk.

Labor board officials found that his comments were personal venting, not the “concerted activity” aimed at improving wages and working conditions that is protected by federal law.

N.L.R.B. officials did not name the reporter or the bartender.

Bomb Attacks in Greece Raise Fear of Revived Radicalism

Angelos Tzortzinis for the International Herald Tribune

Riot police were stationed in front of Villa Amalia, a gathering point in central Athens that has long been home to antiauthoritarian youth and some anarchists. Violence flared after police raids there.

ATHENS — When alarms jolted Christos Konstas awake at 4 a.m. recently, he thought a neighbor’s apartment had caught fire. But as he made his way to the building’s lobby, it was clear something more nefarious had taken place.

The remnants of a crude bomb lay smoldering at the front door.

A police officer, recognizing Mr. Konstas as a television commentator who had often defended the Greek government’s efforts to cope with the financial crisis, pulled him aside. “Another journalist was also just hit,” the officer told him in a low voice. Within minutes, reports emerged of explosions at the homes of three more journalists.

Greece has been dealing with an outbreak of violence in recent weeks, following several months in which such activity seemed to have calmed. On Sunday, a crude bomb exploded at the country’s largest shopping mall in a middle-class suburb of Athens, injuring two security guards and escalating a wave of attacks that have gripped the nation’s attention. No immediate claim of responsibility was made.

The government, which just secured $60 billion in aid from its international creditors, says it is determined to crack down on lawless behavior and to press a safety agenda that, as a candidate, Prime Minister Antonis Samaras had vowed to undertake.

The problem, his opponents say, is that in its bid to restore order the government is provoking exactly the violence it says it is trying to quash. They say the government’s true aim is to distract public attention from a growing tax scandal that threatens the stability of the shaky governing coalition.

They point to a police raid on Dec. 20 on the Villa Amalia, a gathering point in central Athens that has been home to antiauthoritarian youth and some anarchists for two decades. While the Greek authorities called the Villa an “anarchist stronghold,” its occupants described it as a cultural center offering free concerts, an occasional children’s nursery and a space for publishing antiauthoritarian literature.

The police evicted the squatters, arrested eight people and confiscated gas masks, propane gas and hundreds of empty beer bottles that they said could be used to make explosives and firebombs. They conducted a second raid on Jan. 9, arresting 92 squatters who had moved back in and padlocked the building.

Within days of the second raid, violence flared. Attacks were carried out on Greek government offices, banks, businesses and other establishment symbols, including the simultaneous explosions at Mr. Konstas’s building and the homes of the other journalists. The home of the government spokesman’s brother was firebombed. On Monday, unidentified gunmen strafed Mr. Samaras’s party headquarters with an AK-47.

The bomb that was ignited Sunday went off at 11 a.m. inside a shopping center run by a company belonging to one of Greece’s wealthiest men, Spiros Latsis. About 200 people were inside when news organizations received calls warning that a bomb would explode in half an hour. The police evacuated the building and said that an investigation was under way.

So far, no one has been seriously hurt in any of the attacks, which seemed intended more for effect than harm. But they raised questions, Greek antiterrorism officials said, about whether new groups of radical left militants are reviving in the wake of the Villa Amalia eviction, perpetuating a turbulent history of violent episodes that have plagued Greece since the collapse of the military junta in 1974.

To its opponents, the timing of the raids raised questions about the government’s motives. They say that Mr. Samaras’s coalition partners are trying to disentangle themselves from the so-called Lagarde list scandal, involving accusations that they failed to pursue rampant tax evasion by the wealthy and well connected. The publication of the list of more than 2,000 Greeks with bank accounts in Switzerland, which the government was given two years ago but did little with, has threatened his coalition — though on Friday the Greek Parliament voted to investigate the role played by a former finance minister, George Papaconstantinou.
