Chavez not in coma, responding well to treatment: brother

CARACAS Ailing Venezuelan President Hugo Chavez is not in a coma and is responding well to cancer treatment in Cuba, making daily progress, his brother said Saturday.

"Reports that the president is in a coma and that the family is discussing ending life support, are totally false," Adan Chavez, governor of the state of Barinas, said in a statement.

He "continues to respond well to his medical care and to make daily progress in his recovery."

Chavez has been out of public sight since undergoing surgery in Havana on December 11, the fourth such operation in the 18 months since his condition was made public.

Officials have said the fiery leftist leader is suffering from a severe pulmonary infection that has resulted in a "respiratory insufficiency," fueling speculation about his prospects for a full recovery -- and his political future.

The uncertainty surrounding Chavez's condition has rattled Venezuela, the nation with the world's largest proven oil reserves.

The government was forced to postpone the president's scheduled inauguration Thursday, as it became clear that he could not attend. Authorities insist the country's constitution allows Chavez to take the oath of office later on.

But the opposition has cried foul, calling for a medical board to review the absent leader's health -- a demand rejected by the Supreme Court, which said the delayed swearing-in was constitutional.

In Cuba on Saturday, President Raul Castro voiced his support for the Venezuelan leadership, his government's closest and most critical economic and political ally.

Castro made the comments during a meeting with Venezuelan Vice President Nicolas Maduro, who arrived in the Cuban capital late Friday to check on his ailing boss, who had a difficult fourth round of cancer surgery last month.

Raul Castro "expressed his confidence in the ability of the Venezuelan people and their institutions to address and overcome any challenge," a government statement said.

"Raul and Maduro shared their mutual satisfaction with the emotional demonstration of support for Venezuela and President Chavez on January 10 in Caracas," it added.

Two Chavez allies, Argentine President Cristina Kirchner and Peruvian President Ollanta Humala, also arrived in Havana on Friday.

"We all hope for a quick recovery," Humala said.

Kirchner refused to comment on Chavez's health when asked by reporters, saying it should be left to his family. She did, however, thank retired revolutionary icon Fidel Castro, 86, for hosting a luncheon for her in his home Friday.

Like Chavez, Castro has been sidelined by health problems and rarely appears in public since stepping aside as president of the communist country in 2006.

Throughout his illness, first detected in June 2011, Chavez -- in power for 14 years -- has refused to relinquish the powers of the presidency, even when leaving for Cuba for his latest surgery.

The Venezuelan constitution says new elections must be held within 30 days if the president-elect or president dies or is permanently incapacitated, either before he takes office or in the first four years of his six-year term.

CES postscript: The touch laptop, like it or not

Intel showing off touch laptops and desktops at CES.

The laptop was reinvented at CES.

Or maybe I should say there was a vigorous attempt to reinvent the laptop. Because we won't know how successful touch has been until next year this time.

Intel's
CES booth -- still a large presence in the CES Central Hall -- had one basic unmistakable message: touch has arrived.

Windows 8 convertibles, detachables, touch-screen laptops, and just plain
tablets from Hewlett-Packard, Dell, Samsung, Acer, Asus, Lenovo, Toshiba, Sony, and others blanketed Intel's booth.

And just to make sure the touch message was crystal clear, Intel issued an edict to PC partners during its CES keynote: all next-generation ultrabooks based on its "Haswell" chip must be touch.

What does that mean to consumers? Your next laptop will likely be touch, whether you like it or not.

And based on what I saw at the Intel booth (and other booths, like Samsung's), this is how it will break down:

Convertible: Convertibles, like the HP EliteBook Revolve and Lenovo Yoga, have swivel touch screens.

The important thing to remember here is that the Intel processor and related electronics are still under the keyboard, so these systems will tend to be higher performance because the design affords more opportunity to keep the processor cool.

Detachable: These are essentially tablets with well-integrated keyboard docks. They would include the new Lenovo ThinkPad Helix, HP's Envy x2, and Samsung ATIV Smart PC.

Detachables put the processor electronics behind the screen. And that usually forces PC makers to use a lower-performance, more power efficient chip like Intel's "Clover Trail" Atom.

One of the few exceptions to that rule is the ThinkPad Helix, which manages to cram a mainstream Intel Ivy Bridge chip into a tablet.

And, by the way, Intel is now trying to get more PC makers to do this. It has just begun shipping a new Y series Ivy Bridge processor that is more power efficient than the one in the Helix.

Still, battery life won't be terrific, and Ivy Bridge chips -- even the most power-efficient ones -- still require fans to keep them cool.

Touch-screen laptop: This is a traditional clamshell laptop with a touch screen. There are already lots of these out there, including the Sony Vaio T13 Series, the Acer Aspire S7, the Asus VivoBook X202E, and the HP Spectre XT TouchSmart.

And expect a lot more. Maybe by this time next year, the preponderance of laptops on display at your local Best Buy will have touch screens.

Tablet: And then there are devices that are marketed as standalone
Windows 8 tablets. These would include HP's ElitePad 900 and Dell's Latitude 10 tablet.

Tablets that can run the full version of Windows 8 (based on Intel chips) and Windows RT tablets (based on ARM chips) will offer good battery life and a lightweight, slim design but won't be very fast. That is, don't expect them to multitask Microsoft Office, Photoshop, and other demanding applications without bringing the device to its knees.

Not every laptop will go touch, of course. High-end gaming lappies and business laptops will be available with non-touch screens for the foreseeable future. But I suspect that, eventually, even these will go touch.

Dell's XPS 10 Windows RT detachable, based on a Qualcomm Snapdragon S4 processor, was on display at Qualcomm's CES booth. Intel's edict that all future 4th Generation Core-based 'Haswell' Windows 8 laptops be touch is already an imperative on Windows RT.

Pictures: Civil War Shipwreck Revealed by Sonar

A fishing net, likely only decades old, drapes over machinery that once connected the Hatteras' pistons to its paddle wheels, said Delgado.

From archived documents, the NOAA archaeologist learned that Blake, the ship's commander, surrendered as his ship was sinking. "It was listing to port, [or the left]," Delgado said. The Alabama took the wounded and the rest of the crew and put them in irons.

The officers were allowed to keep their swords and wander the deck as long as they promised not to lead an uprising against the Alabama's crew, he added.

From there, the Alabama dropped off their captives in Jamaica, leaving them to make their own way back to the U.S.

Delgado wants to dig even further into the crew of the Hatteras. He'd like see if members of the public recognize any of the names on his list of crew members and can give him background on the men.

"That's why I do archaeology," he said.

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.

Euro adds more gains on dollar

NEW YORK: The euro surged for a second day Friday, adding 0.7 US cents to Thursday's two cent gain, pushed by what one analyst said was short covering and sustained by poor US trade data.

The European currency traded roughly around the break-even line of $1.3261 but then took a leap to the $1.3350 levels the morning opening -- just 15 minutes before US trade data for November showed a wider-than-expected deficit that implied slower growth.

"While a rise in the euro isn't out of the ordinary lately, particularly after yesterday's European Central Bank monetary policy decision and press conference, many euro crosses had settled in to a range in the 18 hours before the spike occurred," said Neal Gilbert of GFT.

He said a Goldman Sachs recommendation with a target for $1.37 could have been the force, but also a squeeze on short sellers.

"Since the market had turned sideways in the Asian and European sessions, many investors were likely assuming a profit taking drop was about to take place."

Now that trade has been flushed out, he added, "the profit taking is more likely to take place."

At 2200 GMT, the euro was at $1.3341, off the day's high of $1.3366.

The yen sagged to its lowest level in more than 30 months, hitting 89.18 yen to the dollar from 88.64 late Thursday.

Against the euro, it hit 119.00 yen, compared to 117.53 Thursday; it was the yens lowest level in 20 months against the euro.

The pound slipped to $1.6129 from $1.6158, and the dollar moved to 0.9135 Swiss francs from 0.9145 francs.

The Chinese currency continued its push higher, to 6.2180 yuan per dollar from 6.2256 a day earlier and 6.2316 a week ago.

$100 to Facebook message Mark Zuckerberg? Bargain!

LAS VEGAS -- I woke up this morning wanting to tell the world about all the fun last night.

I wanted to tell Beyonce about how much one woman told me she had worked in order to get her man to put a ring on it.

I wanted to tell Britney Spears that there were still people in the world who adored her music and some of them are here in Nevada, worried that she's leaving "The X Factor."

And I wanted to tell Facebook CEO Mark Zuckerberg that I had met so many fine young people in Vegas who were simply desperate to be him.

Suddenly, I heard that if I wanted to use Facebook for any of these communications, it might cost me $100.

More Technically Incorrect

Mashable had reported the quite frightening news that some people were being asked to pay such an amount in order to send a Facebook message to the exalted.

Thankfully, the Wall Street Journal had mustered an explanation from Facebook. It appears that the site is concerned about the amount of spam that wafts about its pages. Especially the amount of spam directed at those who have vast and emotional numbers of subscribers.

Facebook is also experimenting with allowing only one message per week to be sent to these immensely popular people whose Facebook pages are probably manned by flunkies, rather than the deities themselves.

I know that many might be outraged at the idea that Facebook might charge such an enormous amount for what might truly amount to painfully meaningless access to the rich, the famous and the notorious. Yet think about what real human beings are prepared to do in order to experience the very slightest proximity -- however much imagined -- with their heroes.

By charging $100, Facebook may not merely be expressing its deep desperation for revenue. It may also tapping into a bottomless and lucrative well of adoration.

There are people who will travel hundreds, if not thousands, of miles in order to (hope to) catch a glimpse of some famous being. There are those who think nothing of paying vast money for a lock of hair that purported to come from some starlet's fur coat.

There are even people who will go out of their way to visit Facebook's own headquarters in Menlo Park, just to be photographed with the company's "like" logo.

Think of the pride people would feel in the sure knowledge that their message to Mark would get through. Think of how they could show off in their status updates: "I just paid $100 to message Mark Zuckerberg." And think how Facebook could then use these status updates to create ads for this $100 message capability.

Once upon a time, Facebook was a place where the masses would congregate and mill. Now, it can be a place where you can genuflect and venerate as you communicate -- and pay good money to do it.

Obama Promises Faster Transition in Afghanistan

President Obama and Afghan President Hamid Karzai said today that most U.S. combat operations in Afghanistan would end this spring, signaling a quickening troop drawdown that will bring the decade-long war to a close at the end of 2014.

"Our troops will continue to fight alongside Afghans when needed, but let me say it as plainly as I can: Starting this spring, our troops will have a different mission -- training, advising, assisting Afghan forces," Obama announced at an East Room news conference in Washington.

"It will be a historic moment and another step toward full Afghan sovereignty, something I know that President Karzai cares deeply about, as do the Afghan people," he said.

Administration officials said Afghan forces were "exceeding initial expectations" in their capabilities. Afghan security forces are expected to lead 90 percent of security operations across the country in February.

"By the end of next year -- 2014 -- the transition will be complete," Obama said. "Afghans will have full responsibility for their security, and this war will come to a responsible end."

The rosy assessments belied the serious political, economic and security challenges that remain.

Left unanswered by Obama and Karzai: How many U.S. troops might stay after 2014; what their mission would be and whether they could be effective; and whether the forces would have immunity from prosecution in Afghan courts.

Obama said he was still reviewing recommendations from the Pentagon and will make an announcement in the coming weeks after penning an anticipated bilateral security agreement with Afghanistan. Karzai said the exact number would be up to the United States to decide.

Both leaders confirmed in a statement that the United States "does not seek permanent bases in Afghanistan."

They also agreed today to turn over battlefield combatants held by the U.S. military in Afghanistan to Afghan government control, which has been long-sought by Karzai.

Roughly 66,000 U.S. troops are serving in Afghanistan. The military has proposed keeping several thousand troops in the country after 2014 as advisers, trainers and logistical support for Afghan forces; the White House has said it remains open to pulling out all troops entirely.

Obama's visit with Karzai was the first face-to-face encounter since the November election and since last year's dramatic increase in so-called green-on-blue attacks, when U.S. and NATO soldiers have been killed by the Afghans they are training or working alongside.

There were 45 insider attacks in 2012 that resulted in 62 deaths among coalition forces, including 35 Americans. There has been one attack already in the first 11 days of 2013.

The White House summit included a private Oval Office meeting between Obama, Karzai and Vice President Joe Biden. The trio also attended a private lunch in the Old Family Dining Room.

Karzai Thursday attended meetings with Defense Secretary Leon Panetta and top military brass at the Pentagon, where he was afforded all the pomp and circumstance accorded a head of state: a 21-gun salute, and marching bands and honor guards from the Army, Navy, Air Force, Marines and Coast Guard.

Karzai's relationship with the United States has at times been a rocky one as he has sometimes made critical statements about the allied troop presence in his country. U.S. officials believe he has made those comments out of political expediency to improve his standing with Afghans and show his independence.

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.
