2012 review: The year in health science

Read more: "2013 Smart Guide: 10 ideas that will shape the year"

The first half of 2012 will be remembered for the saga over whether or not to publish controversial research involving versions of the H5N1 bird flu virus engineered to spread more easily in mammals. In the end openness won out, and both contentious studies did finally see the light of day.

This was also the year that saw the battle to eradicate polio reach its crucial endgame – just as another problem, in the form of totally drug resistant tuberculosis, reared its head.

Away from infectious disease, 2012 brought us a theory on the link between Tutankhamun, epilepsy and the first monotheistic religion, and an insight into the perils of premature ageing in Italy's ominously named Triangle of Death. Here are 10 more of the year's memorable stories.

N.Korea leader vows "radical" economic shift

SEOUL: North Korea's young leader Kim Jong-Un called for a "radical turnabout" in the impoverished country's economy in a rare New Year's address Tuesday that also urged improved relations with the South.

While the heart of his lengthy speech was devoted to turning the North into an "economic giant" and raising living standards, Kim stressed that military power remained a national priority.

"The military might of a country represents its national strength. Only when it builds up its military might in every way can it develop into a thriving country," he said in a voiced message broadcast on state television.

The address will be closely parsed for meaning in South Korea which just elected its first woman president, the conservative Park Geun-Hye, who has signalled a willingness for greater engagement with Pyongyang.

The voiced message was the first of its kind since Kim's grandfather, the North's founding president Kim Il-Sung, delivered one in 1994, the year of his death.

Kim's comments on the economy are likely to fuel speculation that he might be set to implement economic reforms that observers have been predicting since he came to power a year ago after the death of his father Kim Jong-Il.

The year 2013 will be a year of "great creations and changes in which a radical turnabout will be effected," Kim said, adding that "the building of an economic giant is the most important task" facing the country.

Praising the success of the North's space scientists in launching a long-range rocket last month, Kim said a similar national effort was required on the economic front.

"The entire Party, the whole country and all the people should wage an all-out struggle this year to effect a turnaround in building an economic giant and improving the people's standard of living," he said.

When Kim Jong-Il died, he left a country in dire economic straits -- the result of a "military first" policy that fed an ambitious missile and nuclear programme at the expense of a malnourished population.

Despite a rise in staple food output, daily life for millions of Koreans is an ongoing struggle with under-nutrition and a lack of vital protein and fat, according to a recent World Food Programme report.

Some observers had seen a glimmer of reformist hope in the handover of power to the Swiss-educated Kim Jong-Un, only in his late 20s.

Instead, Kim focused on consolidating his power base with a series of high-profile personnel changes, notably within the military elite, while at the same time pursuing Kim Jong-Il's missile programme.

Tuesday's address called for a "radical" increase in output across the board, from light and heavy industry to agriculture, as well as an improved transport infrastructure.

But it offered no specific policy directives for how this might be achieved by the isolated state which relies on its sole major ally China for 70 per cent of its foreign trade.

Kim's address came as the UN Security Council is still considering how to punish Pyongyang for its recent rocket launch, which most of the world saw as a disguised ballistic missile test.

The speech lauded the launch as a historic national achievement and stressed the need to develop more "sophisticated military hardware" in order to bring about a "fundamental change" in combat preparedness.

On South Korea, Kim sounded a conciliatory note and urged a scaling down of tensions on the Korean peninsula.

"An important issue in putting an end to the division of the country and achieving its reunification is to remove confrontation between the North and the South," Kim said.

"The past records of inter-Korean relations show that confrontation between fellow countrymen leads to nothing but war," he said.

South Korean president-elect Park Geun-Hye has distanced herself from outgoing President Lee Myung-Bak's hardline policy towards Pyongyang and spoken of the need for greater engagement with the North.

But in her first post-election victory policy statement, Park made it clear she still viewed Pyongyang as a serious threat and would put the South's national security before any trust-building programme.

Reddit's visitors skyrocket in 2012 with 37 billion page views

Whether readers want to learn the complexities of how the Mars Curiosity rover was able to enter the Red Planet's atmosphere or just see photos of cats being weird, they can go to Reddit. The social news site announced today its end-of-year stats and it appears that users are frequenting the site at an ever-increasing rate.

Reddit revealed that in 2012 it received 37 billion page views, 400 million unique visitors, and 30 million posts -- not bad for one of the most simple Web sites on the Internet.

The site's user population has skyrocketed since its inception. According to The Next Web, Reddit achieved 1 billion monthly page views in February 2011 and by December of that year it more than doubled that number. By October 2012, the site recorded more than 3.8 billion monthly page views and more than 46 million unique visitors.

The huge increase in traffic means Reddit has had to add more servers and other equipment and bring in more staff to maintain its site. This growth has forced it to spend money to keep up with the flow, while also promoting paid subscriptions and advertising.

One of the ways Reddit has driven more traffic to its site this past year is by hosting high-level AMAs, or "ask me anything" sessions. In August, Reddit hosted President Barack Obama, whose impromptu hour-long interview crippled the site's servers. Reddit has also done AMAs with the Mars Curiosity rover team, Gangnam Style's PSY, and U.S. Rep. Zoe Lofgren who asked users for ideas on a bill to protect Web sites accused of copyright violations.

Here are Reddit's top 10 posts of 2012 by page view:

1. I am Barack Obama, President of the United States -- AMA (5,598,171 page views)


2. What's your "picture you can't see without laughing"? (2,450,140 page views)


3. What's your favorite picture on the whole Internet? (2,148,400 page views)


4. Reddit, what do you look like before and after makeup? Is there a real difference? (2,142,071 page views)


5. Today, a homeless looking man handed me $50 and this note. Do any of you have any idea what it means? (1,756,748 page views)


6. What GIF makes you laugh every single time? (1,749,185 page views)


7. I've been playing the same game of Civilization II for almost 10 years. This is the result. (1,651,956 page views)


8. I am South Korean Singer, Rapper, Composer, Dancer and Creator of Gangnam Style PSY. AMA (1,514,034 page views)

  NASA's Solar Dynamics Observatory snapped this extreme ultraviolet view of an active region on the sun as it rotated into view from December 16 to December 18. Ultraviolet light makes it easier to trace the whorls and loops created by superheated gas, or plasma, and the sun's magnetic field lines.

  Active solar regions such as this create space weather that, when aimed at Earth, can disrupt satellite communications and electronics. (See more pictures of solar activity and space weather.)

  The Moshniy glacier, located on the Russian archipelago Novaya Zemlya in the Arctic Ocean, calves chunks of ice and debris into a pattern reminiscent of broccoli in an image released December 20.

  Novaya Zemlya was a sensitive military area during the Cold War, and was also the site of the most powerful nuclear device ever detonated. The energy released by the 50-megaton "Tsar" bomb was ten times that of all the explosions set off during World War II.

Fiscal Cliff Deal Vote Likely in Senate

The so-called "fiscal cliff" came tonight -- but now there is a specific deal on the table to try to soften it after the fact, according to congressional sources.

Senate Majority Leader Harry Reid, D-Nev., said the deal -- brokered by Vice President Joe Biden and Senate Minority Leader Mitch McConnell -- would get a vote in the Senate tonight. The House would not vote before Tuesday, having adjourned for the evening before word of the agreement spread.

"I feel really very, very good about this vote," Biden told reporters leaving the meeting with Senate Democrats, "but having been in the Senate for as long as I have there's two things you shouldn't do: You shouldn't predict how the Senate is going to vote before they vote....[and] you surely shouldn't predict about how the House is going to vote."

The proposal would extend Bush-era tax cuts permanently for people making less than $400,000 per year and households making less than $450,000, the sources said.

The steep "sequester" budget cuts scheduled to go into effect with the New Year would be postponed two months, said sources. They said half the money would come from cuts elsewhere, and the other half from new revenue.

The deal also would affect taxes on investment income and estates, and extend unemployment benefits for a year, the congressional sources added.

"The end is in sight," said a Democratic aide with Senate Majority Leader Harry Reid's office. "If everyone cooperates, it's possible things can move pretty quickly."

After the Biden meeting, Sen. Charles Schumer, D-N.Y., said there was "strong" support for the plan among Senate Democrats.

"There is a feeling that it's not that this proposal is regarded as great or as loved in any way, but it's a lot better than going off the cliff," he said.

Sen. Dianne Feinstein, D-Calif., called the compromise the "best" that could be done.

Even with progress in the Senate tonight, the "cliff" deadline will pass without action by the House, where Republican leaders said they would "consider" the deal starting tomorrow.

'Fiscal Cliff': Lawmakers Scramble for Last-Minute Deal Watch Video

"Decisions about whether the House will seek to accept or promptly amend the measure will not be made until House members -- and the American people -- have been able to review the legislation," said House Speaker John Boehner, Majority Leader Eric Cantor, Majority Whip Kevin McCarthy, and Republican Conference Chair Cathy McMorris Rodgers in a statement.

The failure of a deal to pass Congress by Jan. 1 technically triggers an income tax hike on all Americans and automatic spending cuts, though lawmakers could still prevent a tax hike by making retroactive any legislation that passes in the weeks ahead, experts said.

The deal at hand will not entirely solve the problem of the "fiscal cliff," however. In fact, it could set up a new showdown over the same spending cuts in just two months that would be amplified by a brewing fight over how to raise the debt ceiling beyond $16.4 trillion. That new fiscal battle has the potential to eclipse the "fiscal cliff" in short order.

Earlier, during a midday news conference, Obama said he was optimistic about compromise in the short-term.

"It appears that an agreement to prevent this New Year's tax hike is within sight, but it's not done," he said. "There are still issues left to resolve, but we're hopeful that Congress can get it done."

In addition to extending current tax rates for households making $450,000 or less, the latest plan would raise the estate tax from 35 to 40 percent for estates larger than $5 million; and prevent the alternative minimum tax from hammering millions of middle-class workers, according to sources familiar with the talks.

Capital gains taxes would rise to 20 percent from 15, according to a senior White House official.

The deal would also extend for one year unemployment insurance benefits set to expire Tuesday, and avert a steep cut to Medicare payments for doctors, congressional sources said.

"I can report that we've reached an agreement on the all the tax issues," said Senate Minority Leader Mitch McConnell in an afternoon speech on the Senate floor.

At the time, McConnell said that federal spending cuts remained a sticking point. That hurdle later appeared to be cleared by postponing the debate two more months, though it is unclear whether House Republicans will go along.

"In order to get the sequester moved, you're going to have to have real, concrete spending cuts," said Rep. Mike Rogers, R-Mich. Without that, he said, "I don't know how it passes the House."

Some Republicans also said Obama unduly complicated progress toward an agreement by seeming to take a victory lap on taxes at his campaign-style event at the White House.

"Keep in mind that just last month Republicans in Congress said they would never agree to raise tax rates on the wealthiest Americans," Obama said, raising the ire of several Republicans. "Obviously, the agreement that's currently discussed would raise those rates, and raise them permanently."

Those words drew a sharp retort from Republican Sen. John McCain.

Rather than staging a "cheerleading rally," McCain said, the president should have been negotiating the finishing touches of the deal.

"He comes out and calls people together and has a group standing behind him, laughs and jokes and ridicules Republicans. Why?" said McCain.

Several Democrats also voiced disappointment with the president and the emerging deal.

Swimmer Hackett sues lawyers over pre-nup: report

SYDNEY: Australian swimming great Grant Hackett is suing his lawyers over a costly pre-nuptial agreement after his marriage ended with a drunken rampage, reports said.

After five years together, Hackett and Candice Alley split in May. He had trashed his apartment the previous October in an alcohol-fuelled blowout, prompting his wife to call the police.

Police photographs of the damage were published after which Hackett was dumped as an ambassador for a children's anti-violence charity. He had upended a piano and furniture, smashed a door and put holes in the walls.

The 1,500m freestyle champion at both the 2000 and 2004 Olympics and dominant force in the event for a decade accused his former solicitors of drawing up a "defective" pre-nuptial agreement.

"As a result of the breaches... the Plaintiff (Hackett) has suffered loss including legal costs," legal documents lodged by Hackett in the Supreme Court of Victoria said, according to News Limited newspapers.

"The Plaintiff's loss is continuing."

The newspapers said Hackett's personal fortune was estimated at some A$8 million (US$8.3 million) and he was seeking a finding of negligence against his solicitors along with compensation.

In June, Hackett said he was working to restore his reputation and did not blame alcohol for his actions.

"I will be defined by my actions moving forward and I hope people take the time to judge me on that and I'm very, very determined to turn that around," he said.

"I was drunk, I think the alcohol exaggerated or exacerbated the emotions of that night and made it worse. But I don't blame that, I blame myself."

Yahoo completes withdrawal from South Korean market

As it promised earlier this year, Yahoo has completed its exit from the South Korean market before the end of the year, according to a brief report by the Yonhap News Agency.

Yahoo announced its intention in October to withdraw from the country, saying that the move was a response to "efforts to streamline operations and focus our resources on building a stronger global business that's set up for long-term growth and success."

The South Korean unit, which had been in operation since 1997, consisted of about 200 employees, delivered editorial content and handled the company's advertising efforts in that country. Yahoo's market share in South Korea has been on the decline as users increasingly used competing Web portals, like Naver and Daum.

"The Korean operation has faced growing challenges over the past few years that now make scaling our business very difficult," Yahoo said in a statement in October.

Yahoo isn't the only company having trouble competing in South Korea. Motorola Mobility plans to close "most" of its operations in the country by 2013, according to a leaked internal memo. After long struggling with low handset sales in the Asian country, phone maker HTC closed its doors in South Korea in July.

How to Banish That New Year's Eve Hangover

For those of us who enjoy the occasional cocktail, the holiday season would be incomplete without certain treats of the liquid variety. Some look forward to the creamy charms of rum-laced eggnog; others anticipate cupfuls of high-octane punch or mugs of warm, spiced wine.

No matter what's in your glass, raising one as the year winds down is tradition. What could be more festive? The problem is, one drink leads to two, then the party gets going and a third is generously poured. Soon, the music fades and the morning arrives—and with it, the dreaded hangover. (Explore a human-body interactive.)

Whether it's a pounding headache, a queasy stomach, sweating, or just general misery, the damage has been done. So now it's time to remedy the situation. What's the quickest way to banish the pain? It depends who you ask.

Doctors typically recommend water for hydration and ibuprofen to reduce inflammation. Taking B vitamins is also good, according to anesthesiologist Jason Burke, because they help the body metabolize alcohol and produce energy.

Burke should know a thing or two about veisalgia, the medical term for hangover. At his Las Vegas clinic Hangover Heaven, Burke treats thousands of people suffering from the effects of drinking to excess with hydrating fluids and medications approved by the U.S. Food and Drug Administration.

"No two hangovers are the same," he said, adding that the unfavorable condition costs society billions of dollars-mostly from lost productivity and people taking sick days from work.

Hot Peppers for Hangovers?

So what's the advice from the nonmedical community? Suggestions range from greasy breakfasts to vanilla milkshakes to spending time in a steamy sauna. A friend insists hot peppers are the only way to combat a hangover's wrath. Another swears by the palliative effects of a bloody mary. In fact, many people just have another drink, following the old "hair of the dog that bit you" strategy.

Whether such "cures" actually get rid of a hangover is debatable, but one thing's for sure: the sorry state is universal. The only people immune to hangovers are the ones who avoid alcohol altogether.

So for those who do indulge, even if it's just once in awhile, see our interactive featuring cures from around the world (also above). As New Year's Eve looms with its attendant excuse to imbibe, perhaps it would be wise to stock your refrigerator with one of these antidotes. Pickled herring, anyone?

Hillary Clinton Hospitalized With Blood Clot

(MICHAL CIZEK/AFP/Getty Images)

By DANA HUGHES and DEAN SCHABNER

Secretary Hillary Clinton was hospitalized today after a doctors doing a follow-up exam discovered a blood clot had formed, stemming from the concussion she sustained several weeks ago.

She is being treated with anti-coagulants and is at NewYork-Presbyterian Hospital so that they can monitor the medication over the next 48 hours, Deputy Assistant Secretary Philippe Reines said.

Her doctors will continue to assess her condition, including other issues associated with her concussion. They will determine if any further action is required, Reines said.

Clinton, 65, originally fell ill from a stomach virus following a whirlwind trip to Europe at the beginning of the month, which caused such severe dehydration that she fainted and fell at home, suffering a concussion. No ambulance was called and she was not hospitalized, according to a state department official.

The stomach virus had caused Clinton to cancel a planned trip to North Africa and the United Arab Emirates, and also her scheduled testimony before Congress at hearings on the attack on the U.S. consulate in Benghazi, Libya.

According to a U.S. official, the secretary had two teams of doctors, including specialists, examine her after the fall.  They also ran tests to rule out more serious ailments beyond the virus and the concussion. During the course of the week after her concussion, Clinton was on an IV drip and being monitored by a nurse, while also recovering from the pain caused by the fall.

Medical experts consulted by ABC News said that it was impossible to know for sure the true nature or severity of Clinton’s condition, given the sparse information provided by the State Department. However, most noted that the information available could indicate that Clinton had a deep venous thrombosis,which is a clot in the large veins in the legs.

“A concussion (traumatic brain injury) in itself increases risk of this clot. Likely the concussion has increased her bed rest,” said Dr. Brian D. Greenwald, Medical Director JFK Jonson Rehabilitation Center for Head Injuries. “Immobility is also a risk for DVT. Long flights are also a risk factor for DVT but the recent concussion is the most likely cause.

“Anticoagulants are the treatment,” he said. “If DVT goes untreated it can lead to pulmonary embolism (PE). PE is a clot traveling from veins in legs to lungs which is life threatening. Many people die each year from this.

“Now that she is being treated with blood thinners her risks of PE are decreased,” he said. “Blood thinners carry risk of bleeding but are common and can be safely used.”

Dr. Allen Sills, associate professor of Neurological Surgery at Vanderbilt University Medical Center, said it was most likely that the clot was not located in Clinton’s brain, since she is being treated with anticoagulants.

“This is certainly not a common occurrence after a concussion, and is most likely related to either inactivity or some other injury suffered in the fall,” he said.

Dr. Neil Martin, the head of Neurovascular Surgery at the University of California, Los Angeles, Medical Center, said blood thinners are often given for blood clots in the legs, and it is “very unusual” for anticoagulants to be given for blood clots in the head.

But he cautioned about speculating too much about Clinton’s condition before more information is available.

“If we don’t know where it is, there is the possibility of several different indications,” he said. “I don’t know if there is any connection between what she’s got now and the concussion. All I can tell you is, at this point, it’s almost impossible to speculate unless we know what’s going on there.”
