2013 Smart Guide: Curiosity to reach Mars mother lode

NASA'S Curiosity rover is about to have its cake and eat it too. Around September, the rover should get its first taste of layered sediments at Aeolis Mons, a mountain over 5 kilometres tall that may hold preserved signs of life on Mars.

Previous rovers uncovered ample evidence of ancient water, a key ingredient for life as we know it. With its sophisticated on-board chemistry lab, Curiosity is hunting for more robust signs of habitability, including organic compounds - the carbon-based building blocks of life as we know it.

Observations from orbit show that the layers in Aeolis Mons - also called Mount Sharp - contain minerals thought to have formed in the presence of water. That fits with theories that the rover's landing site, Gale crater, was once a large lake. Even better, the layers were probably laid down quickly enough that the rocks could have held on to traces of microorganisms, if they existed there.

If the search for organics turns up empty, Aeolis Mons may hold other clues to habitability, says project scientist John Grotzinger of the California Institute of Technology in Pasadena. The layers will reveal which minerals and chemical processes were present in Mars's past. "We're going to find all kinds of good stuff down there, I'm sure," he says.

Curiosity will explore a region called Glenelg until early February, and then hit the gas. The base of the mountain is 10 kilometres away, and the rover can drive at about 100 metres a day at full speed. The journey should take between six and nine months, but will include stops to check out any interesting landmarks. After all, some of the most exciting discoveries from Mars rovers were a result of serendipity.

"It's a discovery-driven mission," Grotzinger says. "We picked this site because we wanted to go to Mount Sharp. But we'll kind of follow our nose, and see where it leads us off on side trails."

India's trauma turns to anger at gang-rape killing

NEW DELHI: Horror at a deadly gang-rape that appalled India has turned to anger in New Delhi, where a leaden-footed government is accused of being out of touch and out of ideas in handling its latest crisis.

On Sunday evening, as dusk descended on an area of the Indian capital where protesters have assembled daily since the December 16 rape of a 23-year-old medical student, a group ran through the crowd with an effigy.

It depicted Sheila Dikshit, the 74-year-old chief minister of New Delhi blamed by many for failing to prevent Delhi becoming known as India's "rape capital".

The victim was repeatedly raped and violated with an iron bar on a bus before being thrown off the moving vehicle. She suffered horrific injuries and died on Saturday.

"Tomorrow it could be my sister or me," Soumya Tandon, a 26-year-old marketing executive, told AFP. "I take a bus from near my office and every day my mother is worried if I will reach home safely. Why should we live in constant fear?"

Under the watchful eye of hundreds of riot police, Dikshit's effigy was burnt to cheers, underlining the ugly mood among young urban voters who are increasingly vocal in denouncing their leaders as too old and too complacent.

"We are the future of this nation, they need to connect with us," said 32-year-old Mayuri Goswami, a chartered accountant carrying a banner that read "Time to engage, not disconnect. Wake up, leaders".

"They need to involve us more, try and understand our emotions and anger," he said.

Dikshit, who once said a female journalist murdered in Delhi should not have been so "adventurous" as to be out on her own late at night, is not the only target amid a chorus of calls for change.

Prime Minister Manmohan Singh, an 80-year-old former academic who struggles to connect with voters, called for "dispassionate debate" in a brief statement after the woman's death as the nation was consumed by grief.

As politicians of all stripes struggled to measure the mood and find the right language, the Minister for Women Krishna Tirath failed to make herself heard.

Heavy-handed policing and insensitive comments only stirred more anger.

The president's son, Abhjit Mukherjee, called the protesters "painted ladies", while others blamed provocative clothing and suggested withdrawing skirts at school to curb harassment.

Another protester's poster took aim at Rahul Gandhi, the 41-year-old "youth leader" of the ruling Congress party who is expected to be a prime ministerial candidate in 2014 national elections.

The aloof Oxford graduate -- the latest in the Gandhi political dynasty -- has made few public comments on the crime, which brought simmering anger over widespread abuse of women to boiling point.

"I am not Rahul Gandhi. I have guts to save my sisters," read one banner.

Commentary on the victim's ordeal has tended to place the assault at the centre of forces churning up one of the world's most diverse countries.

Economic growth of nearly 10 percent over the last decade has led to hectic urbanisation that has brought changed moral codes and lifestyles, a more global outlook and globalised trends, as well as simmering class and gender tensions.

Many reasons have been posited for the assault, a commonplace crime in India. A recent poll found it to be the worst in the G20 group of nations for women because of infanticide, child marriage and abuse.

Analysis has focused on India's deeply patriarchal society, in which misogyny runs deep and women are at best second-class citizens and at worst mere objects to be owned, enjoyed or abused by men.

But did the country's gender imbalance as a result of female foeticide play a role? And what about frustration among young Indians in an increasingly sexualised society?

"In our attitudes to sex, we are midway between the liberal democracies of the West and fundamentalist Islamic societies," wrote Palash Krishna Mehrotra, author of "The Butterfly Generation", this week.

In the "old versus new" narrative, most analysts agree that the scandal highlighted the growing battle line between young middle-class urban India -- the future of the country -- and a government still run by men of pensionable age.

Madhuresh Kumar of the non-profit National Alliance of People's Movement, says the protesters represent a new kind of movement which is urban and rooted in globalised, aspirational India.

"This class was till now complacent in its material prosperity," Kumar told AFP.

The millions who protested last year, when anti-corruption campaigner Anna Hazare ignited a national campaign against graft, had a similar profile.

Then as now, a political class seen as unable or unwilling to improve India was widely pilloried as failing to respond to a young population yearning for wealth and security.

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.”

Russia probes Moscow plane crash

MOSCOW: Russian medics began Sunday identifying the bodies of four crew killed when a passenger jet careened off the runway of a Moscow international airport and smashed into a highway.

Rescue workers recovered the flight recorders from the four-year-old Tu-204 of tycoon Alexander Lebedev's Red Wings airlines late Saturday as Russia began mourning its latest post-Soviet crash.

"The plane touched down in the proper landing area but for some reason was unable to stop on the strip," Federal Air Transport Agency chief Alexander Neradko said in televised remarks.

A bigger loss of life was only averted because the 210-seat liner was empty except for eight crew on their return from a charter flight to the Czech Republic.

Cell phone footage of the accident posted on the Internet showed large chunks of debris hurtling over the highway and smashing into cars speeding on the highway whose drivers had to make sudden emergency stops,

The jet split into three pieces and required the temporary shutdown of both the Kiev Highway and Vnukovo -- Moscow's third largest airport and the site of a special terminal for Kremlin officials.

A security source said investigators had brushed aside poor weather conditions or pilot error and were focusing on technical problems with the Tupolev as the most likely cause.

"According to preliminary information, the Vnukovo catastrophe may have been caused by problems with the plane, which became exposed in difficult weather conditions," the unnamed official told the Interfax news agency.

Witnesses said heavy gusts accompanying a light snowfall were swirling over the airport at the time the plane came in for landing on Saturday at 4:45 pm (1245 GMT).

Red Wings owner Lebedev -- a billionaire famous for his critical view of the Kremlin and his ownership of the London Evening Standard and The Independent in Britain -- said the jet had recently passed a meticulous check.

"Plane number 47 had accumulated 8,500 flight hours and underwent its last serious check on November 23," Lebedev tweeted.

He also suggested that traffic controllers' initial refusal to authorise landing -- requiring the plane to complete several circles over Vnukovo -- may have been a contributing factor.

"All machinery has its limits, even when it is new," Lebedev wrote.

Windows 8 wrestles with PC's legacy

I spend precious little time in Metro when using a traditional laptop.

(Credit:
Microsoft)

I'm by no means the first one to say this but
Windows 8 and older PCs make an odd couple.

But let me back up for a second. Before the release of Windows 8 on October 26, I tested Windows 8 on
tablets only, such as the Intel-based Samsung slate that Microsoft sold in its stores. And I was impressed with Metro.

That was then. Windows 8 Pro 64-bit is now installed on my Dell Adamo laptop. And I rarely venture into the Metro UI unless if I'm forced to.

Of course if you're one of the relative few who have a tablet like the Samsung slate or Microsoft's Surface or a touch-screen laptop like Acer's Aspire S7, yeah, then Metro is front and center, as it should be.

But on a traditional laptop it's problematic. That's why Apple, probably the biggest single force behind the rise of the touch interface, hasn't done something similar with its OSes.

Making iOS the launch point and default interface on Macs would not go over well, Steve Job's edict nixing the idea of touch on laptops notwithstanding.

So, Microsoft is going where Apple won't. Intel -- still Microsoft's single most important hardware partner -- is going there too, by the way. The chipmaker said recently that it has chosen Windows 8 "as the standard operating system for Ultrabooks and tablets in our enterprise environment."

But I don't think -- despite Microsoft's upbeat announcement about Windows 8 licenses -- the hundreds of millions of users out there with plain old PCs will warm to the concept of a touch-based launch UI.

Acer's president, Jim Wong, stated this concern rather bluntly to Digitimes this week. The Windows 8 interface could "dramatically delay adoption by consumers," he said.

I'll expand on that by saying that until touch-based laptops and hybrids are both plentiful and cheap, Windows 8 may not gain much traction. And that may take a while.

Let me close on a positive note, though. I like Windows 8. It's faster than
Windows 7 on my Dell and more stable. That's good enough for me.

And Microsoft should spend more time pitching these straightforward Windows 8 merits until touch becomes mainstream.

Woman Charged With Murder in NYC Subway Push

A woman who allegedly told New York City police she pushed a man onto the subway tracks because she hated Hindus and Muslims has been charged with murder as a hate crime.

Erica Menendez, 31, allegedly told police that she "pushed a Muslim off the train tracks because I hate Hindus and Muslims ever since 2001 when they put down the twin towers I've been beating them up."

Menendez was taken into custody this morning after a two-day search, and when detectives were interviewing her she allegedly made the statements implicating herself in Thursday night's subway-platform death.

"The defendant is accused of committing what is every subway commuter's worst nightmare -- being suddenly and senselessly pushed into the path of an oncoming train," Queen District Attorney Richard A. Brown said. "The victim was allegedly shoved from behind and had no chance to defend himself. Beyond that, the hateful remarks allegedly made by the defendant and which precipitated the defendant's actions can never be tolerated by a civilized society."

Menendez was due to be arraigned this evening. She could face 25 years to life in prison if convicted of the second degree murder charge.

On Thursday night, a woman shoved a man from a subway platform at Queens Boulevard, and the man was crushed beneath an oncoming train. Police had searched the area for her after the incident.

New York City Subway Pusher Charged With Murder Watch Video

The victim was Sunando Sen, identified by several media outlets as a graphic designer and Indian immigrant who opened a print shop, Amsterdam Copy, on Manhattan's Upper West Side. Sen was struck by the No. 7 train after the unidentified woman allegedly pushed him from the northbound platform at 40th Street and Queens Boulevard at 8:04 p.m. on Thursday.

Witnesses told police they had seen the woman mubling to herself, pacing along the platform. She gave Sen little time to react, witnesses said.

"Witnesses said she was walking back and forth on the platform, talking to herself, before taking a seat alone on a wooden bench near the north end of the platform. When the train pulled into the station, the suspect rose from the bench and pushed the man, who was standing with his back to her, onto the tracks into the path of the train," NYPD Deputy Commissioner Paul J. Browne said earlier today. "The victim appeared not to notice her, according to witnesses."

Police released brief surveillance video of the woman fleeing the subway station, and described the suspect as a woman in her 20s, "heavy set, approximately 5'5" with brown or blond hair."

It was New York's second death of this kind in less than a month. On Dec. 3, 58-year-old Ki-Suck Han of Queens was shoved onto the tracks at New York's Times Square subway station. Two days later, police took 30-year-old Naeem Davis into custody.

On Friday, New York City Mayor Michael Bloomberg was asked whether the attack might be related to the increase of mentally ill people on the streets following closures of institutions over the past four decades.

"The courts or the law have changed and said, no, you can't do that unless they're a danger to society. Our laws protect you," Bloomberg said on his weekly radio show.
