Video games take off as a spectator sport

Editorial: "Give video games a sporting chance"

EVERY sport has its idols and superstars. Now video gaming is getting them too. Professional gaming, or e-sports, exploded in popularity in the US and Europe last year.

The scene has been big in Asia - particularly South Korea - for about a decade, with top players such as Lim Yo-Hwan earning six-figure salaries and competing for rock-star glory in Starcraft tournaments that attract audiences in the hundreds of thousands.

The phenomenon is taking off in the West partly because of improved video-streaming technology and large financial rewards. Video games are becoming a spectator sport, with certain players and commentators drawing massive online audiences.

And where people go, money follows. The second world championship of League of Legends - a team-based game in which players defend respective corners of a fantasy-themed battle arena - was held in Los Angeles in October. The tournament had a prize pool of $5 million for the season, with $1 million going to winning team Taipei Assassins, the largest cash prize in the history of e-sports.

League of Legends has also set records for spectator numbers. More than 8 million people watched the championship finals either online or on TV - a figure that dwarfs audience numbers for broadcasts of many traditional sports fixtures.

But gamers don't need to compete at the international level to earn money. Video-streaming software like Twitch makes it easy for players to send live footage to a website, where the more popular ones can attract upwards of 10,000 viewers - enough for some to make a living by having adverts in their video streams. Gamers can go pro without leaving their homes.

Currently, e-sports productions are handled by gaming leagues - but that could soon change. Last November saw two moves that will make it even easier to reach a global online audience. First, Twitch announced it would be integrating with Electronic Arts's Origin service, a widely used gaming platform. This would let gamers stream their play at the click of a button, making it easy for people around the world to watch.

Also in November came the latest release from one of gaming's biggest franchises, Call of Duty: Black Ops 2, which has the ability to live-stream via YouTube built into the game itself. Another feature allows the broadcast of in-game commentary for multiplayer matches.

"I think we will reach a point, maybe within five years, where spectator features are a necessity for all big game releases," says Corin Cole of e-sports publishing company Heaven Media in Huntingdon, UK.

David Ting founded the California-based IGN Pro League (IPL), which hosts professional tournaments. He puts the popularity of e-sports down to the demand for new forms of online entertainment. "After 18 months, IPL's viewer numbers are already comparable to college sports in the US when there's a live event," he says. "The traffic is doubling every six months."

Ting sees motion detection, virtual reality and mobile gaming coming together to make physical exertion a more common aspect of video games, blurring the line between traditional sport and e-sports. "Angry Birds could be this century's bowling," says Ting.

Money talks at Obama's inauguration

WASHINGTON: As hundreds of thousands of Americans crowd the National Mall for President Barack Obama's second inauguration on January 21, the best seats will already be filled -- sold for a hefty price.

Obama limited individual donations to $50,000 for his first inaugural in 2009, and banned corporate donors as he sought to distance himself from special interests amid the historic swearing-in of the country's first black president.

His reticence over money did little to stop the flow of cash, however, and the new US leader racked up a record $53 million in private donations, much of it coming from the 1.8 million people who packed Washington for the event.

This second time around, such lofty intentions -- and Obama's pledge to have the most transparent US administration ever -- appear to have been shelved in advance, with companies invited to join in -- and fund -- the proceedings.

For the White House is throwing open the gates of largesse for supporters to contribute as much as $1 million for special access. The money could buy much more than a coveted seat near the president as he takes the oath of office.

"This is an avenue for special interests, especially wealthy corporations, to get their last chance to throw money at the feet of the president," Craig Holman, an expert on campaign finance reform, told AFP.

"The real intent is for the corporations to buy access and influence with the White House," added Holman, from consumer advocacy group Public Citizen.

In this year's invitations, copies of which were posted online by the Sunlight Foundation, an accountability group, the Presidential Inaugural Committee (PIC) formalized four different donation levels -- each with a name of one of the nation's founding fathers.

For $10,000 from individuals and $100,000 from business entities, "Madison" benefactors receive an invitation to a finance committee "road ahead" meeting, two tickets to a candlelight celebration on the eve of the inauguration, and a pair of tickets to the inaugural ball.

"Washington" contributors -- individuals who pay $250,000 and corporations that shell out $1 million -- gain "premium partner access" that also includes attendance at VIP receptions, seats for the inaugural parade, four ball tickets and passes to a concert with Stevie Wonder and Katy Perry.

Just who exactly will be buying in to such events, and how much will they be paying? Right now, it is a mystery.

In 2009, donors and their offerings were published on the Internet, but this year only the names are being disclosed in the short term. The amounts given will be published within 90 days of the inauguration.

A PIC spokesman said the lavish perks were offered to donors to get them to open their wallets one more time to help fund the inaugural festivities, after many of them contributed to the most expensive political race in US history.

The 2012 presidential campaign exceeded $2 billion, partly due to a Supreme Court case that lifted a cap on independent political spending by corporations.

Ironically, inauguration day will coincide with the second anniversary of the landmark Citizens United ruling, but funding fatigue may be setting in with the inaugural committee reportedly struggling to meet its $50 million target.

Private donations cover the party element of the inauguration, while taxpayers foot the bill for security.

According to a congressional report, more than 30,000 police were mobilized for the record inaugural crowd that jammed Washington's National Mall in 2009.

Authorities expect fewer people this year but security remains paramount -- dozens of streets will be closed to traffic and metal detectors will be used to scan the thousands ticketed guests.

The exact number of VIP donors is unknown, but a Department of Homeland Security report indicated that four years ago at least 750 were transported to the west front of the Capitol, where seats were reserved near the podium.

One donor perk that the Washington Post identified as a security breach in 2009 and will likely not be repeated this time around: some VIPs arranged to have their photo taken near the presidential limousine.

Making job stress worth enduring

Defense Secretary Leon Panetta swears in reenlisting troops in Turkey. A survey found that military jobs tend to be the most stressful.

STORY HIGHLIGHTS

• Marci Alboher: Annual list of most stressful jobs drew attention


• She says the right issue is whether job rewards compensate for stress


• People who take on stressful jobs that help others report satisfaction, she says

Editor's note: Marci Alboher, is a Vice President of Encore.org, a nonprofit making it easier for people to pursue second acts for the greater good. Her latest book is, "The Encore Career Handbook: How to Make a Difference and a Living in the Second Half of Life" (Workman: January 2013).

(CNN) -- A recent study with a catchy headline about the most stressful jobs of 2013 found its way to the soft hour of news this week.

The annual study by careercast.com created some buzz in the online water cooler and I was asked to appear on the "Today" show to talk about it. Colleagues e-mailed me and posted on my Facebook page about where their chosen professions ranked. My media friends couldn't help noticing that public relations professionals, reporters and photojournalists all made it into the top 10 for stress.

The "study," referred to in quotes in some of the commentary, considered some logical criteria to come up with these rankings. Proximity to risk of death (yours or others'), travel, deadlines, working in the public eye and physical demands all racked up points on the stress scale. And there's no arguing that military personnel, firefighters and police officers -- all high-rankers on the most-stressed list -- are exposed to higher stakes than your typical seamstress (holder of the second-least stressful job slot).

Marci Alboher

The job that snagged the "least stressful" slot, according to the survey, was "university professor," a designation that caused outrage among people who actually hold that job. One commenter conceded that most academic jobs don't put you in personal danger (though you can argue that point), but anyone who's ever been around professors knows that faculty politics, difficult students and pressure to "publish or perish" can cause even the most calm character to crack.

We could debate whether these designations make any sense. And whether every police officer, firefighter and member of the military faces the same amount of stress.

But let's make sure we are having the right conversation. How many people choose a profession based on how high the stress level is? And how can you measure stress objectively? If you're prone to stress, perhaps you're just as likely to feel stressed out whether you work as a librarian, a massage therapist or a commercial airline pilot (No. 4 on the stress list).

People choose their line of work for a lot of reasons. For those who are committed to making our communities and the world safer and healthier for the rest of us, minimizing stress is probably not so high on their list of criteria. And it shouldn't be. Folks who choose helping jobs that may have a high level of stress are fueled by other motivators, like wanting their work to have meaning.

They aren't deterred by the fact that their job will likely come with stress. And some people are simply by their own nature and personalities drawn to work that may be to others, dauntingly stressful. How many FBI agents do you think would prefer a gig as an audiologist (sixth-least stressful job)?

When I talk to men and women in their 50s and 60s who've decided to take on encore careers as teachers, they tell me that the work is often exhausting and stressful. They are on their feet all day, often with inadequate resources, with kids who are themselves highly stressed; even those who come from leadership roles in other sectors say they've never worked harder. Yet they almost always tell me that doing something that matters to others -- and that puts them in touch with young people every day -- compensates for the added stress.

The same is true of those tackling some of the world's most intractable problems. When I talk to Stephen and Elizabeth Alderman, whose foundation trains health-care professionals around the world to work with victims of trauma, or Judith Broder, who founded The Soldiers Project, which works with returning veterans, they rarely talk about stress. Instead they talk about how they are compelled to do what they do, because moving the needle even a fraction is better than doing nothing.

Rather than discouraging people to take on jobs that might have a lot of stress, let's instead encourage those who are designed for those jobs to do them. And let's make sure to support our friends and family members who go down these paths.

It's hard to grab headlines in the crowded space of morning television, but a good survey with a catchy title will always do that. So let's use these kinds of surveys to have the right kinds of conversations. Like why so many jobs that keep us safe and healthy, and that care for our children and the environment rarely show up on lists of the most highly compensated jobs. Now there's a conversation I'd most like to be having.

Treasury: No $1 trillion coin

A Treasury Department spokesman announced today that the department will not mint a platinum coin to sidestep raising the federal government's borrowing limit, telling the Washington Post that "neither the Treasury Department nor the Federal Reserve believes that the law can or should be used to facilitate the production of platinum coins for the purpose of avoiding an increase in the debt limit."

The idea, which had gained traction among some congressional Democrats and political analysts as a way of defanging the debt ceiling as a bargaining chip, was that the Treasury Department could simply mint a platinum coin, declare the value at $1 trillion, and deposit it into the Federal Reserve to allow continued spending in the absence of a vote to raise the debt ceiling.

With the idea now buried by Treasury, the stage is set for a full-on fight about the debt ceiling. President Obama and congressional Democrats have signaled that they simply will not negotiate on a vote to raise the borrowing limit, saying that it is Congress's duty to pay bills it has already accrued.

But congressional Republicans have given every indication that they plan to use the debt limit as a bargaining chip to extract deep spending cuts from reluctant Democrats.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Lottery Winner Murdered: Widow Questioned By Police Watch Video

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

US study warns of extreme heat, more severe storms

WASHINGTON: A government report warned on Friday that the United States could face more frequent severe weather including heat waves and storms for decades to come as temperatures rise far beyond levels being planned for.

The draft Third National Climate Assessment, a scientific study legally mandated to advise US policymakers, made few bones that carbon emissions have been causing climate change -- a source of controversy among some lawmakers.

"Evidence for climate change abounds, from the top of the atmosphere to the depths of the oceans," the study said. "The sum total of this evidence tells an unambiguous story: The planet is warming."

The study, which was submitted for public and expert review and could be revised, said there was "strong evidence" that human activity had already roughly doubled the probability of extreme heat of the kind seen in Texas and Oklahoma in the summer of 2011.

The assessment expected temperatures to keep rising and offered different scenarios for the future -- including temperatures rising between 2.8 and 5.6 degrees Celsius (5 and 10 degrees Fahrenheit) after 2050 if emissions climb further.

Such a rise would be far beyond the level anticipated by world leaders in UN-backed climate change negotiations, which have committed to holding warming to no more than two degrees Celsius above pre-industrial levels.

The report warned that climate change "threatens human health and well-being in many ways," including through more frequent storms, wildfires, diseases and worse air quality.

Rising sea levels have already damaged infrastructure and climate change could increasingly reduce the reliability of water supplies, particularly in the southern half of the United States and Great Plains, the report said.

While US agriculture will likely remain resilient in the next 25 years, yields of major crops could start declining by mid-century and warming oceans could threaten fish, the study said.

The draft assessment said that some additional climate change was "now unavoidable" but said that the United States still could decide how much to allow.

The draft assessment was released three days after the National Oceanic and Atmospheric Administration said that 2012 was easily the warmest year on record in the continental United States and ranked second for extreme weather.

Environmental advocates hoped that the release of the draft report would bring fresh momentum to efforts to tackle climate change.

"Climate change is taking its toll on people and their economies, and will only become more intense without a strong and rapid response here in the United States and around the globe," Andrew Steer, president of the World Resources Institute, said in a statement.

President Barack Obama has hinted he will make a new effort on climate change in the wake of his November 6 re-election and massive storm Sandy, which killed at least 120 people in the US Northeast.

Efforts by Obama's Democratic Party to mandate cuts in carbon emissions failed in 2010 in the Senate. Lawmakers of the rival Republican Party said that legislation would be too costly and voiced doubt over climate science.

Since then, the Obama administration has ordered higher standards for power plants. US emissions dropped in 2011, largely due to increased use of natural gas instead of coal.

World Bank president Jim Yong Kim, who released a report in November that warned of potentially catastrophic 4.0 degree Celsius warming if no action is taken, said that evidence is "overwhelming" on climate change.

Speaking on Friday at a luncheon honouring Korean Americans, Kim voiced fear that his three-year-old son would live "a world that looks completely different from the world we have today" when he nears his father's age in 2060.

"If you have a three-year-old child, or if you have a three-year-old grandchild, what you've got to understand is, if we don't act aggressively on climate change, the world they live in will be daily fights over access to water, daily fights over access to food," he said.

Why death comes sooner in America

A report finds that Americans have "shorter lives and poorer health," coming in last in key areas behind 16 other rich nations

STORY HIGHLIGHTS

• Aaron Carroll: New study shows U.S. health and lifespan worst of 17 rich countries


• He says it's because of personal choices, systemic woes. Poverty high, health care uneven


• He says this particularly affects youth, plagued by sickness, violence, high mortality


• Carroll: Don't make it political. The richest country in the world must improve public health

Editor's note: Dr. Aaron E. Carroll is an associate professor of pediatrics at the Indiana University School of Medicine and the director of the university's Center for Health Policy and Professionalism Research. He blogs about health policy at The Incidental Economist and tweets at @aaronecarroll.

(CNN) -- A just-released report from the Institute of Medicine and National Research Council is making news by clearly illustrating that Americans have "shorter lives and poorer health." This is somewhat shocking, given how much we spend on health care each year — more than any of the 16 other rich countries surveyed in the study. What's even more upsetting is that this report focused quite heavily on people who are young. In the United States, even that group fared poorly.

Aaron Carroll

Why is this?

Some of the reasons involve choices make at a personal level. We eat too much, abuse drugs too often, wear seat belts too rarely and commit violence against each other to often.

Systemic issues are also to blame. We have higher levels of poverty than comparable countries, and our safety net programs are less capable of catching people when they fall. And too many also have too much trouble accessing the health care system, resulting in inefficient, ineffective and often absent care.

It's far too easy to let these dreadful statistics become obscured in a politically charged argument. Let's avoid that. This report is so stark that it's going to take a concerted effort on the part of the government, the media, the health care system and everyday citizens to turn things around. Our personal choices are bad. Our safety nets are bad. Our health care system is bad. It's all bad. How bad?

When compared with peer countries, the United States was the absolute worst with respect to still births, infant mortality and low birth weight. Some have tried to blame this on "coding" differences. In other words, they will claim that other countries will refuse to define a premature birth as we do, resulting in artificially high numbers in the United States. But when this report recalculated the rates to exclude such births equally in all countries, we still ranked last.

Things don't get better after birth. The chance that a child in the United States will die before age 5 is higher than in any of the other 16 peer countries. Injuries are the most common cause of death, but the United States also has the highest rate of deaths caused by negligence or abuse.

And violence is decidedly an American problem. Homicide is the third most common cause of death in children age 1-4.

From age 5-19, the trend continues. Kids this age in the United States have the worst health ranking of the 17 studied countries. More than one-third of U.S. children age 5-17 are obese or overweight, the highest of any peer country. The adolescent pregnancy rate in the United States is about 3.5 times the average of others. Additionally, the rates of sexually transmitted infections, including syphilis, gonorrhea and chlamydia are the worst compared to peer countries.

Nor are these children exempt from death. Injury deaths are more common in 15- to 19-year-olds in the United States than in any other studied country. Homicide claims the second highest number of lives in 15- to -24-year-olds, and 4 in 5 of those deaths involve guns. Males between the ages of 15 and 19 are five times as likely to die from violence in the United States than in other countries.

Even as young adults, ages 25-34, mortality remains consistently upsetting and preventable. Unintentional injuries remain the No. 1 cause of death. The risk of dying by violence remains seven times higher for males in the United States ages 20-24 than in other countries.

We have to work together to make these numbers better. Some of them can be improved with public health measures. We need to help Americans be less obese, to have fewer accidents and to commit less violence. There are lots of local studies and initiatives that propose ways to fix these things, but our public health system is woefully underfunded, and translating any promising findings to meaningful societal change poses a huge challenge.

We also need to improve our safety nets to help children at the lowest end of the socioeconomic ladder do better, even before they are born. Pregnant women, babies and children suffer from hunger and malnutrition far too often in the richest country in the world. Yet we still debate the merits of the federally funded WIC (Womens, Infants and Children) program, school lunches and food assistance to needy families.

Finally, we need to find a way to improve access to the health care system. The Medicaid program covers one in every three births and one in every three children in the United States, and it's still not enough. As some states balk at expanding Medicaid to cover many of the poorest uninsured, some are still talking about reducing funding to the already stretched program. There's no question that we have the capability, the knowledge and the resources to care for people. It's just a matter of doing it better.

There will be some who deny these results. Others will try to use them for political gain. That would be a mistake. We have to accept these findings and begin to work holistically to improve them. Being last just isn't the American way.

U.S. tells computer users to disable Java software

WASHINGTON The U.S. Department of Homeland Security is advising people to temporarily disable the Java software on their computers to avoid potential hacking attacks.

The recommendation came in an advisory issued late Thursday, following up on concerns raised by computer security experts.

Experts believe hackers have found a flaw in Java's coding that creates an opening for criminal activity and other high-tech mischief.

CNET's Topher Kessler writes:

"The malware has currently been seen attacking Windows, Linux and Unix systems, and while so far has not focused on OS X, may be able to do so given OS X is largely similar to Unix and Java is cross-platform.

Even though the exploit has not been seen in OS X, Apple has taken steps to block it by issuing an update to its built-in XProtect system to block the current version of the Java 7 runtime and require users install an as of yet unreleased version of the Java runtime.

Luckily with the latest versions of Java, users who need to keep it active can change a couple of settings to help secure their systems. Go to the Java Control Panel that is installed along with the runtime, and in the Security section uncheck the option to "Enable Java content in the browser," which will disable the browser plug-in. This will prevent the inadvertent execution of exploits that may be stumbled upon when browsing the Web, and is a recommended setting for most people to do. If you need to see a Java applet on the Web, then you can always temporarily re-enable the plug-in.

The second setting is to increase the security level of the Java runtime, which can also be done in the same Security section of the Java Control Panel. The default security level is Medium, but you can increase this to High or Very High. At the High level, Java will prompt you for approval before running any unsigned Java code, and at the Very High level all Java code will require such approval, regardless of whether or not it is signed."

Java is a widely used technical language that allows computer programmers to write a wide variety of Internet applications and other software programs that can run on just about any computer's operating system.

Oracle Corp. bought Java as part of a $7.3 billion acquisition of the software's creator, Sun Microsystems, in 2010.

Oracle, which is based in Redwood Shores, Calif., had no immediate comment late Friday.

Muscle mimic pulls electricity from wet surface

Electricity has been squeezed from a damp surface for the first time, thanks to a polymer film that curls up and moves – a bit like an artificial muscle – when exposed to moisture. The film could be used to run small, wearable devices on nothing but sweat, or in remote locations where conventional electricity sources aren't available.

When a dry polymer absorbs water, its molecular structure changes. This can, in principle, be converted into larger-scale movement, and in turn electricity. But previous attempts at creating a material powered by a moisture gradient – the difference in chemical potential energy between a wet region and a dry region - failed to produce a useful level of force.

These unsuccessful tries used a polymer called polypyrrole. Now Robert Langer and colleagues at the Massachusetts Institute of Technology have turned to the material again, embedding chains of it within another material, polyol-borate. This more complex arrangement mimics structures found in muscles as well as in plant tissues that bend in response to changes in humidity.

Flipping film

The result looks like an ordinary piece of thin black plastic, but when placed on a wet surface, something extraordinary happens. As the material absorbs water, its end curls away from the surface and the film becomes unstable, so it flips over. The ends have now dried out, so they are ready to absorb more water, and the whole process repeats itself. This continuous flipping motion lets the film travel across a suitably moist surface unaided.

Langer found that a 0.03-millimetre-thick strip, weighing roughly 25 milligrams, could curl up and lift a load 380 times its mass to a height of 2 millimetres. It was also able to move sideways when carrying a load about 10 times its mass.

To extract energy from this effect, Langer's team added a layer of piezoelectric material – one which produces electricity when squeezed. When this enhanced film, weighing about 100 milligrams, flipped over, it generated an output of 5.6 nanowatts – enough to power a microchip in sleep mode.

Electricity from sweat

Though the output is small, it is proof that electricity can be extracted from a water gradient. "To the extent of our knowledge, we are the first to utilise a water gradient, without a pressure gradient, to generate electricity," says Langer.

Large-scale energy harvesting is unlikely as the size of the device needed would be impractical, but it could be used to power small devices such as environmental monitoring systems in remote locations. "It will be interesting for applications where the amount of energy needed may be low but where access to energy may be difficult," says Peter Fratzl at the Max-Planck Institute of Colloids and Interfaces in Potsdam, Germany, who was not involved in the work.

Another application, Langer suggests, would be to place the film inside the clothing of joggers or athletes. The evaporation of sweat could generate enough electricity to power sensors monitoring blood pressure and heart rate.

US flu outbreak claims at least 18 lives

WASHINGTON: The United States was in the grip Thursday of a deadly influenza outbreak that has hit harder and earlier than in previous years, and has claimed the lives of at least 18 children.

"It looks like the worst year we had since 2003-2004," said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

Fauci said this year's influenza strain, which has sickened thousands across the country, is particularly severe.

"The type of flu is one that generally is more serious. It's the H3N2 variety, which is historically more serious than we see with other types of virus," he said.

The epidemic, which broke out at the beginning of December, has caused some 2,200 hospitalizations across the United States, federal health officials said.

Particularly hard hit has been the northeastern city of Boston, where officials have declared a public health emergency.

City officials there said there so far have been about 700 confirmed cases of flu, almost 10 times the number from this time last year.

"This is the worst flu season we've seen since 2009, and people should take the threat of flu seriously," Boston Mayor Thomas Menino said in a statement.

"I'm urging residents to get vaccinated if they haven't already. It's the best thing you can do to protect yourself and your family. If you're sick, please stay home from work or school," he said.

Joe Bresee, chief of the Epidemiology and Prevention Branch of the Centers for Disease Control and Prevention's Influenza division, said officials don't yet know how much worse this year's outbreak will get.

"While we can't say for certain how severe this season will be, we can say that a lot of people are getting sick with influenza and we are getting reports of severe illness and hospitalizations," he said.

US states, particularly in the northeast of the country, have seen a sharp spike in emergency room visits from patients reporting flu-like symptoms, according to the federal CDC in Atlanta.

In Allentown, Pennsylvania, one hospital had to erect a large outdoor tent to admit and treat the large number of flu sufferers.

Health officials said that the flu vaccine is a good match for the strain of influenza circulating around the nation, and confers about 60 per cent to 65 per cent protection against the illness.

"You might get the flu but it will likely be less severe if you are vaccinated," Fauci said.

Beheading exposes exploitation

(File photo) Sri Lankan women protest outside the Saudi Arabia embassy in Colombo on November 9, 2010.

STORY HIGHLIGHTS

• Saudi authorities beheaded Rizana Nafeek, a Sri Lankan woman


• She was convicted of killing a baby of the family employing her as a housemaid


• This was despite Nafeek's claims that the baby died in a choking accident


• Becker says her fate "should spotlight the precarious existence of domestic workers"

Jo Becker is the Children's Rights Advocacy Director for Human Rights Watch and author of 'Campaigning for Justice: Human Rights Advocacy in Practice.' Follow Jo Becker on Twitter.

(CNN) -- Rizana Nafeek was a child herself -- 17 years old according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system, and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system, or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay, and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.

Student shot at Calif. high school by classmate

Updated at 8:33 p.m. ET

TAFT, Calif. A 16-year-old student armed with a shotgun walked into class in a rural California high school on Thursday and shot one student, fired at another but missed, and then was talked into surrendering by a teacher and another staff member, officials said.

The teen victim was in critical but stable condition, Kern County Sheriff Donny Youngblood told a press conference. The sheriff said the teacher suffered a minor pellet wound to the head but declined treatment.

The gunman had as many as 20 rounds of ammunition in his pocket, the sheriff said.

The attack there came less than a month after a gunman massacred 20 children and six women at Sandy Hook Elementary School in Newtown, Connecticut, then killed himself.

That shooting prompted President Barack Obama to promise new efforts to curb gun violence. Vice President Joe Biden, who was placed in charge of the initiative, said he would deliver new policy proposals to the president by next week.

Sen. Dianne Feinstein, a California Democrat, said in a statement that her father had attended Taft Union and she has visited the school over the years.

"At this moment my thoughts and prayers are with the victims, and I wish them a speedy recovery," Feinstein said. "But how many more shootings must there be in America before we come to the realization that guns and grievances do not belong together?"

When the shots were fired, the teacher tried to get the more than two dozen students out a back door and also engaged the shooter in conversation to distract him, Youngblood said. A campus supervisor responding to a call of shots fired also began talking to the gunman.

"They talked him into putting that shotgun down. He in fact told the teacher, `I don't want to shoot you,' and named the person that he wanted to shoot," Youngblood said.

"The heroics of these two people goes without saying. ... They could have just as easily ... tried to get out of the classroom and left students and they didn't," the sheriff said. "They knew not to let him leave the classroom with that shotgun."

The shooter didn't show up for first period then interrupted the class of 28 students.

Investigators had not yet had a chance to interview the student and so had no immediate word on a motive or whether the attacker had a previous disciplinary record. Nor did they know where he got the shotgun.

The wounded student was flown to a hospital in Bakersfield. Officials said a female student was hospitalized with possible hearing damage because the shotgun was fired close to her ear, and another girl received minor injuries during the scramble to flee when she fell over a table.

Officials said there's usually an armed officer on campus but the person wasn't there because he was snowed in. Taft police officers arrived within 60 seconds of first reports.

The shooting happened on the second floor of the school's science building around 9 a.m., according to CBS affiliate KBAK in Bakersfield.

As word spread, Dayna Hopper rushed to the school to pick up her son Joseph Sorensen, 16, and daughter, Cheryle Pryor, 15, who had called from Cheryle's cellphone.

"I panicked. I wanted to puke and just get here," Dayna Hopper told The Bakersfield Californian.

KERO-TV Bakersfield reported that the station received phone calls from people inside the school who hid in closets.

The bell had just rung at a nearby school when teachers began shouting for students to get inside buildings, and the principal used an intercom to tell students to stay inside, Felicity Reich, 13, a student at Lincoln Junior High School, told the newspaper.

Shaken, she held the hand of her mother, Ellie Reich, as she spoke.

About 900 students are enrolled at the high school, which includes 9th through 12th grades. Authorities went room by room through the school and expected to spend the day checking backpacks to make sure no other weapons were on campus.

Masses of parents headed to the school football field to find their children, and officials at other schools took action to protect their students as well, the newspaper said.

Wilhelmina Reum, whose daughter Alexis Singleton is a fourth-grader at a nearby elementary school, got word of the attack while she was about 35 miles away in Bakersfield and immediately sped back to Taft.

"I just kept thinking this can't be happening in my little town," she told The Associated Press.

"I was afraid I was going to get hurt," Alexis said. "I just wanted my mom to get here so I could go home."

The Taft shooting came less than a month after a gunman massacred 20 children and six women at Sandy Hook Elementary School in Newtown, Conn., then killed himself.

That shooting prompted President Barack Obama to promise new efforts to curb gun violence. Vice President Joe Biden, who was placed in charge of the initiative, said he would deliver new policy proposals to the president by next week.

At the state Capitol, Assembly Speaker John Perez, D-Los Angeles, said the thoughts and prayers of legislators were with the people at the Taft school.

"It really is just another very sad moment as we deal with the ongoing reality of gun violence that has captured so much of our attention this last year," Perez said.

Hero Teacher Talks Shooter into Dropping Gun

A California high school teacher is being hailed a hero for talking a 16-year-old shooter into putting down his gun and turning himself in after opening fire on a classroom and wounding another student, police said.

The student victim was taken to a nearby hospital and remains in critical but stable condition, Kern County Sheriff Donny Youngblood told reporters on Thursday.

The teacher, whose name has not yet been officially released by authorities, helped evacuate nearly two dozen students out a door at Taft Union High School in Taft, Calif., while calmly engaging the young gunman, who is a student at Taft Union, in conversation.

The teacher and a campus supervisor, who responded to the gunfire and arrived at the classroom, helped convince the teenager to stop shooting.

"They talked him into putting the shotgun down," Youngblood said.

The shooting began around 9 a.m. in the school's science building and sheriff's deputies were on the scene within one minute of the call. An armed security guard who is typically at the school was not on campus because he had been snowed in, the sheriff said.

Two other students received minor injuries: One reported hearing loss and the other fell over a table. The teacher was shot with a pellet, but refused medical treatment, according to police.

The school's 900 students were evacuated from the building and many of them were met by parents within minutes of the first 911 calls.

Today's shooting comes less than month after 20-year-old Adam Lanza opened fire on an elementary school in Newtown, Conn. killing 20 children and six adults.

Hints of new dark force seen in galactic smash-ups

Colliding clusters of galaxies may hold clues to a mysterious dark force at work in the universe. This force would act only on invisible dark matter, the enigmatic stuff that makes up 86 per cent of the mass in the universe.

Dark matter famously refuses to interact with ordinary matter except via gravity, so theorists had assumed that its particles would be just as aloof with each other. But new observations suggest that dark matter interacts significantly with itself, while leaving regular matter out of the conversation.

"There could be a whole class of dark particles that don't interact with normal matter but do interact with themselves," says James Bullock of the University of California, Irvine. "Dark matter could be doing all sorts of interesting things, and we'd never know."

Some of the best evidence for dark matter's existence came from the Bullet cluster, a smash-up in which a small galaxy cluster plunged through a larger one about 100 million years ago. Separated by hundreds of light years, the individual galaxies sailed right past each other, and the two clusters parted ways. But intergalactic gas collided and pooled on the trailing ends of each cluster.

Mass maps of the Bullet cluster showed that dark matter stayed in line with the galaxies instead of pooling with the gas, proving that it can separate from ordinary matter. This also hinted that dark matter wasn't interacting with itself, and was affected by gravity alone.

Musket shot

Last year William Dawson of the University of California, Davis and colleagues found an older set of clusters seen about 700 million years after their collision. Nicknamed the Musket Ball cluster, this smash-up told a different tale. When Dawson's team analysed the concentration of matter in the Musket Ball, they found that galaxies are separated from dark matter by about 19,000 light years.

"The galaxies outrun the dark matter. That's what creates the offset," Dawson said. "This is fitting that picture of self-interacting dark matter." If dark matter particles do interact, perhaps via a dark force, they would slow down like the gas.

This new picture could solve some outstanding mysteries in cosmology, Dawson said this week during a meeting of the American Astronomical Society in Long Beach, California. Non-interacting dark matter should sink to the cores of star clusters and dwarf galaxies, but observations show that it is more evenly distributed. If it interacts with itself, it could puff up and spread outward like a gas.

So why doesn't the Bullet cluster show the same separation between dark matter and galaxies? Dawson thinks it's a question of age – dark matter in the younger Bullet simply hasn't had time to separate.

New window

The idea complements a previous study that saw evidence for dark forces at work in the Bullet cluster. In 2007 Glennys Farrar of New York University and colleagues said that the smaller cluster was moving too fast for gravity alone to be responsible. They suggested that some mysterious force related to dark matter might be hurrying it along.

Still, two clusters is not a lot to go on. Dawson, Bullock and colleagues are following up with about 20 more galactic collisions to see if they show any unusual behaviours. "I really think that we're almost to the point where we have enough observational data in hand," Dawson said. "We could close the book on self-interacting dark matter."

If the new force does exist, we might soon be able to see its effects on things influenced by dark matter, such as the behavior of black holes or the masses of the first stars, says Douglas Finkbeiner of Harvard University in Cambridge, Massachusetts, who was not involved in the new study.

"The simple thing isn't always the right thing, so I really appreciate that Will is trying to look into these other possibilities," he says.

Louis Strigari of Stanford University in California agrees. "Self-interacting dark matter is worth pursuing because we're still very ignorant," he said. "We're desperate to understand what dark matter is, so any new window is welcome."

Latino should have played lead in 'Argo'

Ben Affleck plays the lead role of Tony Mendez in "Argo," which he also directed.

STORY HIGHLIGHTS

• Oscar nominations on Thursday, and Ben Affleck expected to get one for "Argo"


• Affleck plays real-life Latino who helped diplomats escape in Iran hostage crisis


• Ruben Navarrette: Affleck should have used a Latino actor to play role


• He says it cheats actor out of a job, and the Latino community out of a hero's story

San Diego, California (CNN) -- The upcoming Oscars are no stranger to causes or controversy. And this year, there is a strong dose of both surrounding the film "Argo" -- and its star and director, Ben Affleck.

This controversy bubbled up when the buzz started that Affleck could get an Academy Award nomination for best director when the announcements are made Thursday.

"Argo" tells how an ingenious and daring CIA agent helped orchestrate the rescue of six U.S. diplomats from Tehran during the Iran hostage crisis of 1979-1980. In November 1979, about 300 Islamic students stormed the U.S. Embassy and 66 Americans were taken hostage. But six U.S. diplomats escaped and were hidden at the Canadian Embassy by the Canadian ambassador and his wife.

Ruben Navarrette Jr.

The CIA agent -- Antonio "Tony" Mendez, played by Affleck -- successfully led the mission to evacuate the Americans, which involved Mendez and his associates posing as a Canadian film crew that was eager to make a movie in Iran.

The real Tony Mendez was awarded the Intelligence Star for Valor, and other honors, for leading the rescue. He later wrote a memoir, detailing the events in Tehran.

"Argo" is loosely based on Mendez's book. Better make that, very loosely based. As movie critics and others have pointed out since the movie opened a few months ago, the filmmakers took lots of dramatic license with the story. Mendez's role is played up, while that of the Canadians who helped hide and protect the Americans is played down. Some scenes depicted in the film never happened. Some characters are composites of several real people.

In other words, it's what you would expect from a Hollywood feature film based on a historical event. It's not a documentary. It's meant to be taken with a grain of salt, and to be entertaining.

Still, there are some Latinos -- in and out of Hollywood -- who think that, in this case, the filmmakers, and especially Affleck, pushed the concept of creativity too far. They say Affleck missed an opportunity to put more Latinos on screen. Moreover, they say, Affleck improperly claimed, for himself, the choice role of Mendez when he should have cast a Latino actor instead. They insist that the director didn't just cheat a Latino out of an acting job but the Latino community out of a feel-good story about one of their own who won acclaim for a heroic deed.

The critics are right, and their cause is just. Affleck should have tried to cast a Latino to play Mendez. That's common sense, and it would have made "Argo" a better movie. Affleck also didn't do himself any favors by trying to dismiss the criticism with a glib remark that essentially said that it really doesn't matter that the actor playing Mendez isn't Latino since Mendez himself isn't, shall we say, overtly Latino.

At a recent forum intended to publicize the film, Affleck responded to a question from the audience about the controversy by noting that "Tony does not have, I don't know what you would say, a Latin/Spanish accent" and that "You wouldn't necessarily select him out of a line of 10 people and go 'This guy's Latino.' "

Ouch. At least Affleck didn't slip and say "line up."

"So I didn't feel as though I was violating something," he said, "where, here's this guy who's clearly ethnic in some way and it's sort of being whitewashed by Ben Affleck the actor."

Johnny Depp set a better example. Several months ago, Depp turned down the role of Mexican revolutionary Francisco "Pancho" Villa in another film. He said that the role should go to a Latino. I praised Depp at the time for showing that, besides being a great actor, he is also a person of character.

The exclusion of Latinos from Hollywood is an old story. This is still a black and white world, where Latinos rarely get cast in the leading role. We're the gardeners and housekeepers, the gang leader and drug dealers, the nannies and farm workers. That's it. There has been some progress, of course. But not enough -- not when you have a Latina in the Supreme Court, three Latinos in the U.S. Senate, and Latinos heading Fortune 500 companies.

I could blame the environment of Southern California, in which most Hollywood writers, producers and directors live and spend most of their time. When they get up in the morning and drive to work, most Latinos they encounter are subservient. We clean their homes, cook their breakfast, trim their hedges, park their cars and otherwise help them get through the day.

Still, you can push this argument too far, and wind up going down a dangerous path -- one that ultimately sets back the greater cause of trying to get television networks and film studios to create a broader range of meatier roles for Latino actors and actresses.

After all, it's a short walk from saying that a director should have cast a Latino to play a Latino to arguing that only Latinos can play Latinos. And, if that's the argument, then on what moral high ground do Latinos stand to also push -- as we should -- for Latino actors and actresses to be considered for generic and mainstream roles that could have gone to white actors? We can't have it both ways.

Even if Latinos succeed in making their point about this one director and this one movie, it could backfire. We could win this battle, and still lose the war.

But before Latinos can be fully integrated into America and not considered outsiders, we have to take every opportunity to push for inclusion and fairness. And acknowledging that Latinos have the skills to play themselves is a good start.

Leaked video shows teens joking about Ohio rape case

The threats are part of a series of online messages that have targeted individuals and authorities in Steubenville amid increased attention over two high school football players who are facing rape charges.

Jefferson County Sheriff Fred Abdalla said Wednesday he'd provided the FBI a copy of an anonymous Facebook post in which someone threatened to kill his family.

Steubenville Police Chief William McCafferty said he gave the FBI an email that he had opened Wednesday morning, which then disabled his computer.

FBI spokesman Todd Lindgren said he could not immediately comment.

The two teenage boys are set for trial next month in juvenile court on charges they raped a 16-year-old in August. Their attorneys have denied the charges in court.

Much of the evidence in the case played out on social media, in which the photos of the seemingly unconscious girl were posted online. A video published and then deleted from YouTube shows a third freshman, Michael Nodianos, joking about the alleged rape.

The hacking collective Anonymous has staged rallies in support of the alleged victim, and hackers were able to dig up and re-post the deleted YouTube video online.

According to the Steubenville Herald Star, Nodianos' attorney said someone hacked into his client's email and social media accounts, as well as the email accounts of his family members. He has since dropped out of Ohio State University, where he was slated to attend on a scholarship.

Pruney fingers give us better grip underwater

WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.

Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.

To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.

With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.

So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Football: Liga-dominated FIFPro World XI raises eyebrows

LONDON: With Spanish clubs having supplied all 11 members of the FIFPro World XI for 2012, La Liga's claim to be considered the world's best league appears stronger than ever.

Barcelona and Real Madrid may have missed out in last season's Champions League, losing to Chelsea and Bayern Munich respectively, but they still supplied 10 of the players voted into FIFA's all-star team by over 55,000 professional footballers around the world.

Atletico Madrid's Colombian striker Radamel Falcao completed the line-up, meaning that for the first time in the eight-year history of the selection, all 11 players were drawn from teams playing in the same country.

In recent years, coinciding with Spain's dominance of both club and international football, the make-up of the FIFPro World XI has crystallised around a small coterie of players.

Serial Ballon d'Or-winner Lionel Messi has been a mainstay of the side since 2007, Iker Casillas and Xavi since 2008, and Andres Iniesta and Cristiano Ronaldo have been included in the team for the past four years.

In fact, so enduring is the appeal of the players at Spain's top two clubs that there were only two changes to the 11 voted into the FIFPro World XI in 2011.

Manchester United pair Wayne Rooney and Nemanja Vidic were the men to make way, for Falcao and Madrid's Brazilian left-back Marcelo, as the English Premier League had its grip on the team prised away finger by finger.

England has at least mustered representation in recent years, which is more than can be said for the German Bundesliga and France's Ligue 1, while the leading lights from Italy's Serie A have been ignored since 2010.

Amid criticism that the FIFPro selection amounts to nothing more than a glorified popularity contest, dissenting voices have emerged.

Germany captain Lothar Matthaus, present at the Ballon d'Or ceremony in Zurich, claims "people were shaking their heads" when the line-up was announced, while Chelsea left-back Ashley Cole jokingly tweeted: "#iwantspanishpassport."

Given the Spanish national team's stellar achievements in 2012 and the enduring brilliance of Messi and Ronaldo, it is difficult to quibble with much of the team, but there is room for conjecture.

Xabi Alonso won the league with Madrid and scored twice against France in the Euro 2012 quarter-finals, but his performances in Poland and Ukraine were eclipsed by those of Italy's Andrea Pirlo.

The elegant Juventus midfielder narrowly missed out to Iniesta in the voting for the player of the tournament and UEFA technical director Andy Roxburgh described his displays as "magnificent".

His Italy and Juve team-mates Gianluigi Buffon and Giorgio Chiellini also enjoyed excellent years, including success in Serie A, although both were members of the back line pierced four times by Spain in the Euro 2012 final.

In attack, Manchester United striker Robin van Persie, Zlatan Ibrahimovic of Paris Saint-Germain and Chelsea's Champions League hero Didier Drogba all presented strong cases for inclusion as well, albeit not with a Spanish accent.

FIFPro World XI 2012:

Iker Casillas (ESP/Real Madrid); Dani Alves (BRA/Barcelona), Gerard Pique (ESP/Barcelona), Sergio Ramos (ESP/Real Madrid), Marcelo (BRA/Real Madrid); Xabi Alonso (ESP/Real Madrid), Xavi (ESP/Barcelona), Andres Iniesta (ESP/Barcelona); Lionel Messi (ARG/Barcelona), Radamel Falcao (COL/Atletico Madrid), Cristiano Ronaldo (POR/Real Madrid)
