Megan Fox struggles with Twitter

The pain. The anguish.

Twitter is an acquired taste.

There are some who bathe in its immediacy and randomness. Others raise an eyebrow in condescending contemplation.

Hundreds of thousands of sentient beings were recently uplifted when Megan Fox, she of many wonderful movies whose names one doesn't always remember -- decided to plunge into Twitter's dark waters.

She set up an account. She offered some unrehearsed lines.

Then on Wednesday, her fifth day tweeting, she hit a wall: "5 days on Twitter and I have yet to discern it's purpose. #WhatIsThePoint ???"

Some of her more than 260,000 followers implored her to keep going. They suggested she offer her "thoughts." Some merely begged her to tell them how much she loved them.

One, @FechoX, replied wisely: "@meganfox there's no such thing as a point on Twitter... but you if you want I'll explain you over dinner.

Fox seemed unmoved.

Worse, she turned to the pages of a deadly competitor -- yes, Facebook -- to make a horrific announcement:

Some of you may, or may not have noticed by now that my Twitter account has been shut down...I thought that 2013 might be the year that I finally blossomed into a social networking butterfly... but as it turns out I still hate it. Love you guys but I will just never be that girl. Facebook is as much as I can handle.#I'm Sorry

More Technically Incorrect

In an astonishing act of misguided support, 87,744 of her Facebook fans clicked the "like" button in support of these words.

But I bring news. Fox's Twitter account has not (yet) been shut down. I just opened it. It is very much alive, though barely wriggling.

Is this the time for the 266,964 who follow her on Twitter to stand up against the 314,497 who are talking about her Facebook page -- which has received a quite blockbusterish 39,386,101 "likes"?

Megan, Twitter is about spontaneity, bad spelling, and the occasional regret.

It isn't like Facebook. Facebook is for the ponderous, the dull, the ancient. All the teens say so.

And you know you need to take the teens with you, don't you?

Pictures: Civil War Shipwreck Revealed by Sonar

Photograph by Jesse Cancelmo

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.

Rockefeller to retire from US Senate

WASHINGTON: Veteran Democrat Jay Rockefeller of West Virginia announced Friday that he will not seek re-election to the US Senate next year, providing Republicans a prime opportunity to pick up a seat.

The lawmaker has been a longtime defender of the rights of laborers and the poor, and was an initial supporter of using US military force against the regime of Iraq's Saddam Hussein before becoming a fierce critic of US president George W. Bush and his war policies.

"As I approach 50 years of public service in West Virginia, I've decided that 2014 will be the right moment for me to find new ways to fight for the causes I believe in," Rockefeller said in a statement released as he spoke to supporters and media in state capital, Charleston.

"Championing those most in need has been my life's calling, and I will never stop fighting to make a difference for the people who mean so much to me."

Rockefeller, 75, a two-term West Virginia governor, was first elected to the Senate in 1984.

He is a great-grandson of oil tycoon John Rockefeller, and the only Democrat in the Republican family dynasty to serve in national politics.

Rockefeller is chairman of the Senate Committee on Commerce, Science and Transportation, where he said he has led "exhilarating fights... to make our cars more efficient, our phone bills more truthful, our Coast Guard more agile, and the Internet more safe."

He also served as chairman of the powerful Senate Intelligence Committee in the wake of the terror attacks of September 11, 2001 and helped implement reform of the intelligence community.

President Barack Obama lauded Rockefeller's "lifetime of service" and said his fellow Democrat would be missed on Capitol Hill.

"From his time in the state legislature to the governor's office to the Senate floor, Jay has built an impressive legacy, one that can be found in the children who have better schools, the miners who have safer working conditions (and) the seniors who have retired with greater dignity," Obama said in a statement.

Rockefeller stressed that he would not shy away from the challenges facing lawmakers in the next two years, notably a looming series of fiscal battles.

"We've got a really rough debt ceiling in several weeks coming up," he said, referring to the debate over extending US borrowing authority. "I want to be part of that fight."

Rockefeller's departure sets up a succession scramble, with Republicans eager to chip away at the Democrats' 55-45 hold of the 100-seat Senate.

House Republican Shelley Capito has announced in November that she would run for Rockefeller's seat in 2014.

Since his first Senate victory Rockefeller has mostly coasted to re-election, but with Obama deeply unpopular in West Virginia, no one doubts the difficulty the senator would have faced in winning a sixth term.

West Virginia, among the poorest states in the nation, voted Democratic in presidential elections from 1988 to 1996, but from 2000 onward it has been reliably Republican.

Although a West Virginia Republican has not served in the Senate since 1958, Capito has cited the recent political shift as a sign that Republicans now have a strong shot.

Congressman Nick Rahall, a 19-term Democrat, hailed Rockefeller as a lawmaker who "pledged his heart, mind and strength" to West Virginians ever since he first went to the state as an anti-poverty worker in the early 1960s.

John McAfee brings his `Where's Waldo' act to Portland

CBS News)

Last time we checked, John McAfee was on the lam from -- well, whoever it was that he said was after him in Belize. But the former software mogul, who was deported to the United States after fleeing to Guatemala, has decided to pitch his tent in Portland for a while. (Assuming, of course, that he's not yanking the media's chain for kicks and giggles.)

Willamette Week snagged an interview with McAfee who said he was "looking for a home here and plans to live Portland for the next year and a half while he collaborates with local artist Chad Essley on a graphic novel about his life."

"I like the weather. I don't like the sun," he told his interviewer. "This is perfect. I've got enough sun for a while. I had five years of everyday sunny..Nothing wrong with rain, rain is good...it cleans the streets. It makes for a new ambiance, a little bit darker. I'm in a darker mood these days.

In November Police in Belize searched for McAfee, one of the pioneers of antivirus software, for questioning about the murder of his neighbor, American expat Gregory Faull. That began a month-long case of hide-and-seek as McAfee went on the lam from the authorities, all the while telling his story to a transfixed media that he was being wrongfully persecuted by officials in Belize and that he feared for his life if was arrested.

Biggest Thing in Universe Found—Defies Scientific Theory

Talk about a whopper—astronomers have discovered a structure in the universe so large that modern cosmological theory says it should not exist, a new study says. (Also see "Giant 'Blob' Is Largest Thing in Universe [2006].")

Using data from the Sloan Digital Sky Survey, an international team of researchers has discovered a record-breaking cluster of quasars—young active galaxies—stretching 4 billion light-years across.

"This discovery was very much a surprise, since it does break the cosmological record as the largest structure in the known universe," said study leader Roger Clowes, an astronomer at University of Central Lancashire in England.

For comparison, our own galaxy, the Milky Way, is just a hundred thousand light-years across, while the local supercluster of galaxies in which it's located, the Virgo Cluster, is only a hundred million light-years wide.

Giant Quasar a Head-Scratcher

Astronomers have known for years that quasars can form immense clusters that stretch to more than 700 million light-years across, said Clowes. But the epic size of this group of 73 quasars, sitting about 9 billion light-years away, has left them scratching their heads.

That's because current astrophysical models appear to show that the upper size limit for cosmic structures should be no more than 1.2 billion light years.

"So this represents a challenge to our current understanding and now creates a mystery—rather than solves one," Clowes said. (Also see "Dark Galaxies Discovered—May Be Cosmic 'Missing Links.'")

The titanic structure, known simply as the Large Quasar Group (LQG), also appears to break the rules of a widely accepted cosmological principle, which  says that the universe would look pretty much uniform when observed at the largest scales.

"It could mean that our mathematical description of the universe has been oversimplified-and that would represent a serious difficulty and a serious increase in complexity," Clowes said.

Decoding Early-Galaxy Evolution

Significant not only for its record-breaking size, the massive structure could possibly shed light on the evolution of galaxies like our own Milky Way. Quasars, which pump out powerful jets of energy, are among the brightest and most energetic objects from when the universe was still young. They represent an early, but brief, stage in the evolution of most galaxies. (See "Earliest Known Galaxies Spied in Deep Hubble Picture.")

One theory holds that this type of colossal collection of quasars may be precursors to galaxy superclusters in the modern universe—but the exact nature of their connection is still a mystery.

The discovery, a prime target for computer modeling, also needs to be mapped out more thoroughly with telescopes, said Gerard Williger, an astronomer at the University of Louisville in Kentucky not connected with the study.

"This structure is bigger than we expect based on the shockwaves formed in the universe after the big bang," said Williger.

"There is very likely some mechanism [that] is turning on quasars over a large scale like this—and in a short time—which could relate to some condition in the early universe."

Th quasar study was published this week in the Monthly Notices of the Royal Astronomical Society.

Poisoned Lottery Winner's Exhumation Approved

A judge has approved the exhumation of the Chicago lottery winner who died of cyanide poisoning.

Judge Susan Coleman of the Probate Division of the Cook County Circuit Court in Illinois today approved the county medical examiner's request to exhume the body of Urooj Khan at Rosehill Cemetery in Chicago.

Khan, 46, died July 20, 2012, from what was initially believed to be natural causes. But a family member whose identity has yet to be revealed asked the medical examiner's office to re-examine the cause of death, which was subsequently determined to be cyanide poisoning.

The office did so by retesting fluid samples that had been taken from Khan's body, including tests for cyanide and strychnine.

In explaining the request for exhumation, Chief Medical Examiner Stephen Cina has said, "If or when this goes to court, it would be nice to have all the data possible."

The Chicago businessman had won a $1 million lottery jackpot -- before taxes -- the month before he died.

In the latest legal twist, 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 "receives her proper share." Khan reportedly did not have a will.

He left behind a widow, Shabana Ansari, 32, and a teenage daughter from his first marriage. Ansari and Khan reportedly married 12 years ago in India.

Authorities questioned Ansari in November and searched the home she shared with Khan. She and her attorney, Al Haroon Husain, say she had nothing to do with his death.

"It's sad that I lost my husband," she told ABC News. "I love him and I miss him. That's all I can say."

The siblings of the poisoned lottery winner have pursued legal action to protect their niece's share of her late father's estate. They also questioned whether he and Ansari were legally married, but Ansari's attorney said she has a marriage certificate from India that is valid in the United States.

ImTiaz Khan, 56, Khan's brother, and Meraj Khan, 37, their sister, had won a court order to freeze the lottery winnings after Ansari cashed the check.

Husain said Ansari cashed the lottery check after it was mailed to the home, which she did not request.

The lottery check, about $425,000 in cash, was issued July 19 by the Illinois Comptroller's Office, then mailed, according to Brad Hahn, spokesman for the Comptroller's Office. Hahn said it was cashed Aug. 15, nearly a month after Khan's death, but he did not know who cashed it.

The judge later approved Ansari's competing claim as an administrator of the estate.

"I don't care what they talk [sic]," Ansari told ABC News of what her in-laws are saying.

Ansari said she was married to Khan but declined to comment to ABC News about cashing the check after his death, although The Associated Press has reported that she denied removing any of the assets.

Meraj Khan filed in September to become the legal guardian of her niece. After the judge asked the 17-year old daughter with whom she wished to live, she chose her aunt and has been there since November, Husain said.

Neither sibling has petitioned to obtain a share of the dead man's estate, which is estimated to be $1.2 million in lottery winnings, real estate, Khan's laundry business and automobiles.

Neither the attorney for ImTiaz Khan nor the two siblings has responded to requests for comment.

A status hearing on the future of the estate is scheduled for Jan. 24, according to the AP.

ABC News' Alex Perez and Matthew Jaffe contributed to this report.

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 focused on Syria's chemical arms after Assad: Panetta

WASHINGTON: The United States is increasingly focused on how to secure Syria's chemical weapons if President Bashar al-Assad falls from power but is not considering sending ground troops into the war-torn country, Defense Secretary Leon Panetta said Thursday.

While the US government has issued stern warnings to Damascus against resorting to such arms in its war with rebel forces, Panetta said that a more likely scenario might be a chaotic vacuum if Assad is toppled, with uncertainty over who controls the lethal weapons.

"I think the greater concern right now is what steps does the international community take to make sure that when Assad comes down, that there is a process and procedure to make sure we get our hands on securing those sites," Panetta told a news conference. "That I think is the greater challenge right now."

The US government was discussing the issue with Israel and other countries in the region, he said, but ruled out deploying American ground forces in a "hostile" setting.

"We're not talking about ground troops," Panetta added.

The US military's top officer, General Martin Dempsey, told the same news conference that if Assad chose to use his chemical stockpiles against opposition forces, it would be virtually impossible to stop him.

Preventing the launch of chemical weapons "would be almost unachievable... because you would have to have such clarity of intelligence, you know, persistent surveillance, you would have to actually see it before it happened," he said. "And that's unlikely, to be sure."

He said that clearly worded warnings to Assad from President Barack Obama have served as a deterrent.

Even if the regime chooses not to employ the weapons, the Obama administration worries that Islamist militants allied with rebel forces might gain control of some chemical sites.

Syria's chemical weapons stockpile, which dates back to the 1970s, is the biggest in the Middle East, but its precise scope remains unclear, according to analysts.

The country has hundreds of tons of various chemical agents, including sarin and VX nerve agents, as well as older blistering agents such as mustard gas, dispersed in dozens of manufacturing and storage sites, experts say.

But it remains unclear if the chemical weapons are mounted and ready to be launched on Scud missiles, if the chemical agents are maintained effectively, and whether the regime is able to replenish its chemical stocks.

Damascus has said it might use its chemical weapons if attacked by outsiders, although not against its own people.

Panetta's comments came as prospects for international diplomacy to halt the violence in Syria appeared bleak.

The regime blasted the UN-Arab League envoy, Lakhdar Brahimi, a day before he was due to hold talks with US and Russian officials, accusing him of "flagrant bias."

The 21-month civil war has claimed more than 60,000 lives, according to the United Nations.
