Herbal Viagra actually contains the real thing

IF IT looks too good to be true, it probably is. Several "herbal remedies" for erectile dysfunction sold online actually contain the active ingredient from Viagra.

Michael Lamb at Arcadia University in Glenside, Pennsylvania, and colleagues purchased 10 popular "natural" uplifting remedies on the internet and tested them for the presence of sildenafil, the active ingredient in Viagra. They found the compound, or a similar synthetic drug, in seven of the 10 products – cause for concern because it can be dangerous for people with some medical conditions.

Lamb's work was presented last week at the American Academy of Forensic Sciences meeting in Washington DC.

Chavez working amid chemotherapy: VP

CARACAS: Venezuelan President Hugo Chavez is still in charge and mulling political, social and economic policies even as he receives a new round of chemotherapy, his vice president said Saturday.

Vice President Nicolas Maduro said that the socialist leader, who is convalescing in seclusion at a Caracas military hospital, sent "guidance" to his Cabinet as recently as Friday.

"He is staying informed and in charge as chief who was ratified by our people various times," Maduro said during an event broadcast on state-run television. "Comandante Chavez is the supreme leader of the Bolivarian revolution."

The opposition says the government is lying about Chavez's condition and has voiced doubts that the 58-year-old president held a five-hour meeting with his Cabinet on February 22 as the government claims.

But Maduro repeated that the meeting took place and that the president sent more instructions the next day with Science Minister Jorge Arreaza, his son-in-law, before giving more guidance on Friday.

The leftist leader's chosen successor showed a dossier containing "political, social and economic actions" that Chavez has requested "to continue strengthening the economy to face the economic war of the parasitic bourgeoisie."

The "central document" will be sent to Chavez, he said, adding that the government was "respecting his treatment, we are not acting in an invasive way in his treatment."

Chavez, who was first diagnosed with cancer in June 2011, underwent a fourth round of surgery in Cuba in December.

Maduro disclosed for the first time late Friday that Chavez began a new cycle of chemotherapy in January and decided to return to Caracas last month to continue a "more intense" phase of treatment.

The world is better off with Best Buy alive than dead

Despite all the flak Best Buy gets from consumers and financial analysts, the world is probably a better place with it than without it.

For those who don't follow Best Buy as a business, existential questions have been dogging it for years. The word "Titanic" often comes up.

Not all that surprising, considering brick-and-mortar electronics retail stalwarts CompUSA and Circuit City have all but disappeared.

Here's what the new CEO, Hubert Joly, said Friday during the earnings conference call, via a transcript provided by Seeking Alpha.

"In fiscal '13, we permanently closed 49 large-format stores and expected to close an additional 5 to 10 large-format stores in fiscal 2014."

That's a lot of store closings.

"People who thought we were dead have to go through the painful process of revisiting that point of view," Mr. Joly told The Wall Street Journal on Friday.

I've wondered many times if my regular weekly visit to the local Best Buy would be my last. And still do.

But I like knowing the store is there.

Best Buy is really the only electronics specialty store besides Fry's Electronics (mostly a West Coast phenomenon) that packs lots of PCs, Macs,
tablets, and phones into relatively small abutting areas, allowing you to easily comparison shop.

And Best Buy carries a good cross section of the most popular gadgets. It had Microsoft's Surface tablet pretty soon after the device came out, despite some initial display hiccups (see photo below), and it has decent stock of
Windows 8 touch-screen laptops and tablets,
Android stuff, and of course Apple products.

Of course, there's plenty to complain about. But those same gripes apply to Fry's and to just about any big box electronics retailer that's ever existed, including Circuit City and CompUSA.

What's ahead for Best Buy? Who knows? But Apple stores and now Microsoft's expanding retail presence aren't making it any easier. And during Friday's call, Best Buy executives kept talking about expanding/improving the store's online presence.

Problem is, online is often the last gasp for physical big box retailers.

Nothing to see here. Not that atypical for a Best Buy display. I went to my local Los Angeles store looking for Microsoft's Surface tablet the other day and I found this mess.

We Didn’t Domesticate Dogs. They Domesticated Us.

In the story of how the dog came in from the cold and onto our sofas, we tend to give ourselves a little too much credit. The most common assumption is that some hunter-gatherer with a soft spot for cuteness found some wolf puppies and adopted them. Over time, these tamed wolves would have shown their prowess at hunting, so humans kept them around the campfire until they evolved into dogs. (See "How to Build a Dog.")

But when we look back at our relationship with wolves throughout history, this doesn't really make sense. For one thing, the wolf was domesticated at a time when modern humans were not very tolerant of carnivorous competitors. In fact, after modern humans arrived in Europe around 43,000 years ago, they pretty much wiped out every large carnivore that existed, including saber-toothed cats and giant hyenas. The fossil record doesn't reveal whether these large carnivores starved to death because modern humans took most of the meat or whether humans picked them off on purpose. Either way, most of the Ice Age bestiary went extinct.

The hunting hypothesis, that humans used wolves to hunt, doesn't hold up either. Humans were already successful hunters without wolves, more successful than every other large carnivore. Wolves eat a lot of meat, as much as one deer per ten wolves every day-a lot for humans to feed or compete against. And anyone who has seen wolves in a feeding frenzy knows that wolves don't like to share.

Humans have a long history of eradicating wolves, rather than trying to adopt them. Over the last few centuries, almost every culture has hunted wolves to extinction. The first written record of the wolf's persecution was in the sixth century B.C. when Solon of Athens offered a bounty for every wolf killed. The last wolf was killed in England in the 16th century under the order of Henry VII. In Scotland, the forested landscape made wolves more difficult to kill. In response, the Scots burned the forests. North American wolves were not much better off. By 1930, there was not a wolf left in the 48 contiguous states of America.  (See "Wolf Wars.")

If this is a snapshot of our behavior toward wolves over the centuries, it presents one of the most perplexing problems: How was this misunderstood creature tolerated by humans long enough to evolve into the domestic dog?

The short version is that we often think of evolution as being the survival of the fittest, where the strong and the dominant survive and the soft and weak perish. But essentially, far from the survival of the leanest and meanest, the success of dogs comes down to survival of the friendliest.

Most likely, it was wolves that approached us, not the other way around, probably while they were scavenging around garbage dumps on the edge of human settlements. The wolves that were bold but aggressive would have been killed by humans, and so only the ones that were bold and friendly would have been tolerated.

Friendliness caused strange things to happen in the wolves. They started to look different. Domestication gave them splotchy coats, floppy ears, wagging tails. In only several generations, these friendly wolves would have become very distinctive from their more aggressive relatives. But the changes did not just affect their looks. Changes also happened to their psychology. These protodogs evolved the ability to read human gestures.

As dog owners, we take for granted that we can point to a ball or toy and our dog will bound off to get it. But the ability of dogs to read human gestures is remarkable. Even our closest relatives-chimpanzees and bonobos-can't read our gestures as readily as dogs can. Dogs are remarkably similar to human infants in the way they pay attention to us. This ability accounts for the extraordinary communication we have with our dogs. Some dogs are so attuned to their owners that they can read a gesture as subtle as a change in eye direction.

With this new ability, these protodogs were worth knowing. People who had dogs during a hunt would likely have had an advantage over those who didn't. Even today, tribes in Nicaragua depend on dogs to detect prey. Moose hunters in alpine regions bring home 56 percent more prey when they are accompanied by dogs. In the Congo, hunters believe they would starve without their dogs.

Dogs would also have served as a warning system, barking at hostile strangers from neighboring tribes. They could have defended their humans from predators.

And finally, though this is not a pleasant thought, when times were tough, dogs could have served as an emergency food supply. Thousands of years before refrigeration and with no crops to store, hunter-gatherers had no food reserves until the domestication of dogs. In tough times, dogs that were the least efficient hunters might have been sacrificed to save the group or the best hunting dogs. Once humans realized the usefulness of keeping dogs as an emergency food supply, it was not a huge jump to realize plants could be used in a similar way.

So, far from a benign human adopting a wolf puppy, it is more likely that a population of wolves adopted us. As the advantages of dog ownership became clear, we were as strongly affected by our relationship with them as they have been by their relationship with us. Dogs may even have been the catalyst for our civilization.

US Seeks to Confirm Report of Terror Leader's Death

American military and intelligence officials said today they are attempting to confirm a report from the Chadian military of the death of al Qaeda leader Mokhtar Belmokhtar, the alleged mastermind of the deadly attack on an Algerian natural gas facility in January.

If the new report is confirmed, Belmokhtar's death would be a significant victory against a growing al Qaeda threat in northern Africa.

Belmokhtar's killing was announced on Chadian national television by armed forces spokesperson Gen. Zacharia Gobongue, who said Chadian troops "operating in northern Mali completely destroyed a terrorist base."

"The [death] toll included several dead terrorists, including their leader, Mokhtar Belmokhtar," he said.

However, an unidentified elected official in Mali told The Associated Press he doubted Belmokhtar had actually been killed and said he suspected the Chadian government of pushing the story to ease the loss of dozens of Chadian troops in operations in northern Africa.

Belmokhtar is known as Mr. Marlboro because of the millions he made smuggling cigarettes across the Sahara, but in the last few months the one-eyed terrorist leader has become one of the most sought after terrorists in the world. The attack on the plant near In Amenas in eastern Algeria left dozens of Westerns and at least three Americans dead.

Belmokhtar had formed his own al Qaeda splinter group and announced he would use his wealth to finance more attacks against American and Western interests in the region and beyond.

The U.S. has badly wanted Belmokhtar stopped and actively helped in the search by French and African military units to find him, as well as another top al Qaeda leader who was reported killed yesterday.

After the Chadian announcement, House Foreign Affairs Committee Chairman Rep. Ed Royce (R-Calif.) said Belmokhtar's death, if confirmed, "would be a hard blow to the collection of jihadists operating across the region that are targeting American diplomats and energy workers."

Steve Wysocki, a plant worker who survived the attack in In Amenas thanked "military forces from around the world," especially the Chadian military, for bringing "this terrorist to an expedient justice."

"My family and I continue to mourn for our friends and colleagues who didn't make it home and pray for their families," Wysocki told ABC News.

The CIA has been after Belmokhtar since the early 1990s, Royce's statement said.

ABC News' Clayton Sandell contributed to this report.

Chilling documentary accuses Sri Lanka of war crimes

GENEVA: The Sri Lankan military committed numerous war crimes during the final months of the country's 26-year civil war, according to a documentary aired for the first time on Friday, amid vigorous protests from Colombo.

Using graphic video and pictures taken both by retreating Tamil Tiger rebels, civilians and victorious Sri Lankan troops, "No Fire Zone -- The Killing Fields of Sri Lanka" presents a chilling picture of the final 138 days of the conflict that ended in May 2009.

Filmmaker Callum Macrae insisted before the screening that the film at the UN headquarters in Geneva that it should be seen as "evidence" of the "war crimes and crimes against humanity" committed by government troops.

"The real truth is coming out," he said.

Sri Lanka's ambassador in Geneva, Ravinatha Aryasinha, strongly protested the screening of the film on the sidelines of the ongoing UN Human Rights Council.

He described it as "part of a cynical, concerted and orchestrated campaign" to influence the debate in the council about his country.

Human Rights Watch and Amnesty International, which hosted the screening, are calling for the council to order an international probe.

They charge that Sri Lanka's domestic Lessons Learnt and Reconciliation Commission (LLRC) has glossed over the military's role.

The film for instance alleges that a "no fire zone" set up by the government in January, 2009, basically functioned as a trap for the hundreds of thousands of civilians who flooded into it in the hope of finding safety.

The area was heavily shelled, and in the film maimed and bloodied bodies, of men, women and children, lay strewn.

The UN has estimated that some 40,000 people were killed in the final months of the war, most of them due to indiscriminate shelling by the Sri Lankan military.

Peter Mackay, a UN worker who was trapped inside the zone for two weeks, questioned in the film why the government would set up the "no fire zone" within range of all of their artillery.

"Either you don't care if you kill the people in that safe zone or you are actively targeting them," he said, adding that he believed the latter was true.

He and others describe how aid-centres and make-shift hospitals were shelled soon after UN or Red Cross workers informed the government of their coordinates, which is ironically standard practice to ensure that such places are spared in bombing campaigns.

The footage provided by the retreating Tamil Tigers and civilians is devastating, showing parents wailing over their dying and dead children, but the images provided by the government forces are perhaps even more shocking.

Video of a Tamil Tigers commander first being interrogated, and then a picture of his mutilated body in the dirt; naked and bound prisoners coldly executed; dead, naked women, who have clearly been sexually abused filmed amid degrading comments by onlooking soldiers.

And then there is footage of the 12-year-old son of Tamil Tiger leader Velupillai Prabhakaran, Balachandran, whose body is seen with five bullet holes in his chest.

He was not caught in cross-fire: a separate video shot two hours earlier, shows him sitting in military custody in a bunker eating a biscuit.

The Sri Lankan government has cast doubt on the authenticity of the footage, with Aryasinha insisting on Friday it was of "dubious origin".

Macrae however insisted that all the footage had been carefully checked and analysed to ensure none of it had been tampered with.

"All of it is, I'm afraid, genuine," he said.

Black Hole Spins at Nearly the Speed of Light

A superfast black hole nearly 60 million light-years away appears to be pushing the ultimate speed limit of the universe, a new study says.

For the first time, astronomers have managed to measure the rate of spin of a supermassive black hole—and it's been clocked at 84 percent of the speed of light, or the maximum allowed by the law of physics.

"The most exciting part of this finding is the ability to test the theory of general relativity in such an extreme regime, where the gravitational field is huge, and the properties of space-time around it are completely different from the standard Newtonian case," said lead author Guido Risaliti, of the Harvard-Smithsonian Center for Astrophysics (CfA) and INAF-Arcetri Observatory in Italy. (Related: "Speedy Star Found Near Black Hole May Test Einstein Theory.")

Notorious for ripping apart and swallowing stars, supermassive black holes live at the center of most galaxies, including our own Milky Way. (See black hole pictures.)

They can pack the gravitational punch of many million or even billions of suns—distorting space-time in the region around them, not even letting light to escape their clutches.

Galactic Monster

The predatory monster that lurks at the core of the relatively nearby spiral galaxy NGC 1365 is estimated to weigh in at about two million times the mass of the sun, and stretches some 2 million miles (3.2 million kilometers) across-more than eight times the distance between Earth and the moon, Risaliti said. (Also see "Black Hole Blast Biggest Ever Recorded.")

Risaliti and colleagues' unprecedented discovery was made possible thanks to the combined observations from NASA's high-energy x-ray detectors on its Nuclear Spectroscopic Telescope Array (NuSTAR) probe and the European Space Agency's low-energy, x-ray-detecting XMM-Newton space observatory.

Astronomers detected x-ray particle remnants of stars circling in a pancake-shaped accretion disk surrounding the black hole, and used this data to help determine its rate of spin.

By getting a fix on this spin speed, astronomers now hope to better understand what happens inside giant black holes as they gravitationally warp space-time around themselves.

Even more intriguing to the research team is that this discovery will shed clues to black hole's past, and the evolution of its surrounding galaxy.

Tracking the Universe's Evolution

Supermassive black holes have a large impact in the evolution of their host galaxy, where a self-regulating process occurs between the two structures.

"When more stars are formed, they throw gas into the black hole, increasing its mass, but the radiation produced by this accretion warms up the gas in the galaxy, preventing more star formation," said Risaliti.

"So the two events—black hole accretion and formation of new stars—interact with each other."

Knowing how fast black holes spin may also help shed light how the entire universe evolved. (Learn more about the origin of the universe.)

"With a knowledge of the average spin of galaxies at different ages of the universe," Risaliti said, "we could track their evolution much more precisely than we can do today."

Obama Signs Order to Begin Sequester Cuts

President Obama and congressional leaders today failed to reach a breakthrough to avert a sweeping package of automatic spending cuts, setting into motion $85 billion of across-the-board belt-tightening that neither had wanted to see.

President Obama officially initiated the cuts with an order to agencies Friday evening.

He had met for just over an hour at the White House Friday morning with Republican leaders House Speaker John Boehner and Senate Minority Leader Mitch McConnell and his Democratic allies, House Minority Leader Nancy Pelosi, Senate Majority Leader Harry Reid and Vice President Joe Biden.

But the parties emerged from their first face-to-face meeting of the year resigned to see the cuts take hold at midnight.

"This is not a win for anybody," Obama lamented in a statement to reporters after the meeting. "This is a loss for the American people."

READ MORE: 6 Questions (and Answers) About the Sequester

Officials have said the spending reductions immediately take effect Saturday but that the pain from reduced government services and furloughs of tens of thousands of federal employees would be felt gradually in the weeks ahead.

Sequestration Deadline: Obama Meets With Leaders Watch Video

Sequester Countdown: The Reality of Budget Cuts Watch Video

Federal agencies, including Homeland Security, the Pentagon, Internal Revenue Service and the Department of Education, have all prepared to notify employees that they will have to take one unpaid day off per week through the end of the year.

The staffing trims could slow many government services, including airport screenings, air traffic control, and law enforcement investigations and prosecutions. Spending on education programs and health services for low-income families will also get clipped.

"It is absolutely true that this is not going to precipitate the crisis" that would have been caused by the so-called fiscal cliff, Obama said. "But people are going to be hurt. The economy will not grow as quickly as it would have. Unemployment will not go down as quickly as it would have. And there are lives behind that. And it's real."

The sticking point in the debate over the automatic cuts -- known as sequester -- has remained the same between the parties for more than a year since the cuts were first proposed: whether to include more new tax revenue in a broad deficit reduction plan.

The White House insists there must be higher tax revenue, through elimination of tax loopholes and deductions that benefit wealthier Americans and corporations. Republicans seek an approach of spending cuts only, with an emphasis on entitlement programs. It's a deep divide that both sides have proven unable to bridge.

"This discussion about revenue, in my view, is over," Boehner told reporters after the meeting. "It's about taking on the spending problem here in Washington."

Boehner: No New Taxes to Avert Sequester

Boehner says any elimination of tax loopholes or deductions should be part of a broader tax code overhaul aimed at lowering rates overall, not to offset spending cuts in the sequester.

Obama countered today that he's willing to "take on the problem where it exists, on entitlements, and do some things that my own party doesn't like."

But he says Republicans must be willing to eliminate some tax loopholes as part of a deal.

"They refuse to budge on closing a single wasteful loophole to help reduce the deficit," Obama said. "We can and must replace these cuts with a more balanced approach that asks something from everybody."

Can anything more be done by either side to reach a middle ground?

The president today claimed he's done all he can. "I am not a dictator, I'm the president," Obama said.

Mystery ring of radiation briefly encircled Earth

What were you doing last September? The charged particles that dance around Earth were busy. Unbeknown to most earthlings, a previously unseen ring of radiation encircled our planet for nearly the whole month – before being destroyed by a powerful interplanetary shock wave.

We already knew that two, persistent belts of charged particles, called the Van Allen radiation belts, encircle Earth. The discovery of a third, middle ring by NASA's twin Van Allen probes, launched in August 2012, suggests that these belts, which have puzzled scientists for over 50 years, are even stranger than we thought. Working out what caused the third ring to develop could help protect spacecraft from damaging doses of radiation.

Charged particles get trapped by Earth's magnetic field into two distinct regions, forming the belts. The inner belt, which extends from an altitude of 1600 to 12,900 kilometres, is fairly stable. But the outer belt, spanning altitudes ranging from 19,000 to 40,000 kilometres, can vary wildly. Over the course of minutes or hours, its electrons can be accelerated to close to the speed of light, and it can grow to 100 times its usual size.

Mystery acceleration

No one is sure what causes these "acceleration events", although it seems to have something to do with solar activity interacting with the Earths' magnetic field.

"That's one of the key things the probes are in place to understand," says Dan Baker of the University of Colorado, Boulder. "How does this cosmic accelerator, operating just a few thousand miles above our head, accelerate electrons to such extraordinarily high energies?"

When the Van Allen probes started taking data on 1 September 2012, one of these mysterious events was already under way. "We came in the middle of the movie there," Baker says. But otherwise, he says, "What we expected was what we saw when we first turned on: two distinct belts, separated."

That changed a day later when, to the team's surprise, an extra ring developed between the inner and outer ones. "We watched it develop right before our eyes," Baker says. The new, middle ring was relatively narrow, and its electrons had energies between 4 and 7.5 megaelectronvolts - about the same as in the outer Van Allen belt during an acceleration event.

Although the outer ring displayed its characteristic inconstancy, the new middle ring barely budged for nearly four weeks. Then a shock wave, probably linked to a burst of solar activity, wiped it out in less than an hour on 1 October.

Spacecraft malfunctions

It's not clear where the middle ring came from, Baker says, although it was probably related to the acceleration event. The electrons could have been stripped from the outer Van Allen belt, funnelled back towards the Earth and got trapped in the middle on the way, or they could have been energised from closer to Earth and shot up to higher altitudes.

Figuring out what happened could be important to protecting spacecraft from radiation damage, says Yuri Shprits of the University of California in Los Angeles, who was not involved in the observations but is crafting a theoretical explanation that he hopes to publish soon. "It truly presents us with a very important question, and very important puzzles," he says.

There were no specific spacecraft malfunctions during September that can be directly linked to the new belt, says Shprits. However satellite operators will want to know if such belts are common and if they pose more of a risk.

With no other examples of a transient belt caught so far, it's too soon to answer all those questions, Baker says. "We only have one in captivity," he says. "We're still trying to figure out exactly how it works."

Needy families on public assistance scheme to get higher payouts

SINGAPORE: From April, Public Assistance (PA) recipients can look forward to a higher level of assistance that is flexible and customised to their needs.

The Ministry of Social and Family Development (MSF) will enhance the PA scheme by providing additional assistance, other than a higher direct cash handout.

The change will mainly benefit those with special or once-off needs.

For example, additional assistance will be given to those who need healthcare and hygiene products such as adult diapers and nutritional milk supplements, or those who need once-off purchase or replacement of equipment such as a commode.

The ministry expects about one-third of existing PA households to benefit from the additional forms of assistance.

There are currently over 3,000 households on public assistance.

The cash assistance for all PA households will also be increased. The increase will range from S$50 per month for a one-person PA household to S$130 per month for a four-person PA household.

PA families with dependent children will continue to receive additional cash assistance of S$150 per child.

The ministry also added that the revision is part of the regular review of basic cash assistance rates to ensure that they are adequate to meet the needs of PA households.

Do Not Track privacy bill reintroduced in Senate

Senator Jay Rockefeller

A new bill intended to grant more privacy protections to Internet users was introduced today by U.S. Sen. Jay Rockefeller.

Dubbed "Do-Not-Track Online Act of 2013," the bill would make it law for all Web browsers, online companies, and app makers to give users a choice of opting out of being tracked online, according to The New York Times. Advertisers and data brokers commonly track users to collect information on sites visited, search queries, purchasing patterns, and more.

"The privacy of Americans is increasingly under assault as more and more of their daily lives are conducted online," Rockefeller told The New York Times.

The senator proposed a similar bill in 2011 but then dropped it after industry groups said they would voluntarily develop ways for users to opt out. However, the industry groups were unable to come to an agreement with consumer rights groups about how to create such mechanisms.

"Industry made a public pledge to develop do-not-track standards that will truly protect consumer privacy -- and it has failed to live up to that commitment," Rockefeller told the Times. "They have dragged their feet long enough."

According to The New York Times, these industry groups argue that tracking is necessary because it helps advertisers show users pertinent ads, which pay for the sites. Also, tracking is more or less anonymous -- since data trackers follow IP addresses rather than users directly; so, industry groups say, no significant information about users is revealed.

Several Web browsers and tech companies have already given users Do Not Track options. Google built Do Not Track support into its Chrome Web browser in February 2012; and Yahoo implemented a Do Not Track service across its entire global network last March. Mozilla, Microsoft, and AOL have also committed to working with Do Not Track technology.

However, without a law, browsers and companies aren't required to comply with user wishes to opt out. Therefore, Rockefeller has decided to push his new bill to Congress.

In addition to giving users an opt-out choice, the Do-Not-Track Online Act of 2013 would also allow the Federal Trade Commission to go after those companies that aren't complying with the law. The FTC would also be required to create the mechanisms that would let users say whether or not they want to be tracked.

Despite many attempts to introduce legislation, federal Internet privacy laws are scarce. The last major law to be passed that regulated online companies was 15 years ago with the Children's Online Privacy Protection Act.

Scarred Duckbill Dinosaur Escaped T. Rex Attack

A scar on the face of a duckbill dinosaur received after a close encounter with a Tyrannosaurus rex is the first clear case of a healed dinosaur wound, scientists say.

The finding, detailed in the current issue of the journal Cretaceous Research, also reveals that the healing properties of dinosaur skin were likely very similar to that of modern reptiles.

The lucky dinosaur was an adult Edmontosaurus annectens, a species of duckbill dinosaur that lived in what is today the Hell Creek region of South Dakota about 65 to 67 million years ago. (Explore a prehistoric time line.)

A teardrop-shaped patch of fossilized skin about 5 by 5 inches (12 by 14 centimeters) that was discovered with the creature's bones and is thought to have come from above its right eye, includes an oval-shaped section that is incongruous with the surrounding skin. (Related: "'Dinosaur Mummy' Found; Have Intact Skin, Tissue.")

Bruce Rothschild, a professor of medicine at the University of Kansas and Northeast Ohio Medical University, said the first time he laid eyes on it, it was "quite clear" to him that he was looking at an old wound.

"That was unequivocal," said Rothschild, who is a co-author of the new study.

A Terrible Attacker

The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History in Florida, speculate the creature was attacked by a T. rex.

It's likely, though still unproven, that both the skin wound and the skull injury were sustained during the same attack, the scientists say. The wound "was large enough to have been a claw or a tooth," Rothschild said.

Rothschild and DePalma also compared the dinosaur wound to healed wounds on modern reptiles, including iguanas, and found the scar patterns to be nearly identical.

It isn't surprising that the wounds would be similar, said paleontologist David Burnham of the University of Kansas Biodiversity Institute, since dinosaurs and lizards are distant cousins.

"That's kind of what we would expect," said Burnham, who was not involved in the study. "It's what makes evolution work—that we can depend on this."

Dog-Eat-Dog

Phil Bell, a paleontologist with the Pipestone Creek Dinosaur Initiative in Canada who also was not involved in the research, called the Edmontosaurus fossil "a really nicely preserved animal with a very obvious scar."

He's not convinced, however, that it was caused by a predator attack. The size of the scar is relatively small, Bell said, and would also be consistent with the skin being pierced in some other accident such as a fall.

"But certainly the marks that you see on the skull, those are [more consistent] with Tyrannosaur-bitten bones," he added.

Prior to the discovery, scientists knew of one other case of a dinosaur wound. But in that instance, it was an unhealed wound that scientists think was inflicted by scavengers after the creature was already dead.

It's very likely that this particular Edmontosaurus wasn't the only dinosaur to sport scars, whether from battle wounds or accidents, Bell added.

"I would imagine just about every dinosaur walking around had similar scars," he said. (Read about "Extreme Dinosaurs" in National Geographic magazine.)

"Tigers and lions have scarred noses, and great white sharks have got dings on their noses and nips taken out of their fins. It's a dog-eat-dog world out there, and [Edmontosaurus was] unfortunately in the line of fire from some pretty big and nasty predators ... This one was just lucky to get away."

Mysterious Escape

Just how Edmontosaurus survived a T. rex attack is still unclear. "Escape from a T. rex is something that we wouldn't think would happen," Burnham said.

Duckbill dinosaurs, also known as Hadrosaurs, were not without defenses. Edmontosaurus, for example, grew up to 30 feet (9 meters) in length, and could swipe its hefty tail or kick its legs to fell predators.

Furthermore, they were fast. "Hadrosaurs like Edmontosaurus had very powerful [running] muscles, which would have made them difficult to catch once they'd taken flight," Bell said.

Duckbills were also herd animals, so maybe this one escaped with help from neighbors. Or perhaps the T. rex that attacked it was young. "There's something surrounding this case that we don't know yet," Burnham said.

Figuring out the details of the story is part of what makes paleontology exciting, he added. "We construct past lives. We can go back into a day in the life of this animal and talk about an attack and [about] it getting away. That's pretty cool."

Arias Recounts Each Moment of Stabbing, Slashing

Accused murderer Jodi Arias was forced to recount today each detail of how she killed her ex-boyfriend, Travis Alexander, including re-enacting how he allegedly tackled her when she shot him, leaving her crying in her hands on the witness stand.

During hours of dramatic cross-examination by prosecutor Juan Martinez, Arias bawled as he asked her about stabbing, slashing and shooting Alexander on June 4, 2008.

"You would acknowledge that Mr. Alexander was stabbed, and that the stabbing was with the knife, and it was after the shooting according to you, right?" Martinez said in rapid succession.

"Yes, I don't remember," Arias said, covering her face with her hands.

"Do you acknowledge the stab wounds, and we can count them together, were to the back of the head and the torso?" Martinez said, flashing a photo of Alexander's bloodied body onto the courtroom projector. " Do you want to take a look at the photo?"

Arias, burying her face in her hands and shutting her eyes on the stand, mumbled, "No."

Alexander's sisters, seated in the front row of the gallery, also looked away, crying.

Arias, 32, is accused of killing Alexander on June 4, 2008 out of jealousy. He was stabbed 27 times, his throat was slashed and he was shot in the head twice.

Arias claims she killed in self-defense after Alexander had become increasingly violent with her. She could face the death penalty if convicted.

Martinez also forced Arias to demonstrate in court today how she claims Alexander lunged at her "like a linebacker," causing her to fire the gun at him. The pair argued over how exactly Alexander was positioned, and Martinez pushed her to explain what she meant.

"He lunges at me like a linebacker," Arias said.

"Like a linebacker, what does that mean?" Martinez asked.

"He was low. It was almost like he dove," she said, and trying to explain it further, added, "He was like a linebacker is the only way I can describe it unless I get up to act it out which I'd rather not do."

Timeline of the Jodi Arias Trial

"Go ahead and do it," Martinez said. "Just stand. Go ahead."

Judge Sherry Stephens initially cleared the court as Arias demonstrated and then Martinez had her do it again after the jury and spectators were allowed back into the courtroom.

Standing and moving away from the witness box, Arias bent at the waist and spread out her arms and meekly made a slight lunging motion.

According to her testimony, Arias fired the gun as Alexander rushed at her, tackling her to the ground. She said she does not remember how she stabbed or slashed him.

It was a day of dramatics and anger as the prosecution pressed Arias on the details of the killing, with Martinez ending the afternoon of questioning by accusing Arias of lying throughout her direct testimony.

At one point Arias dissolved into tears, unable to answer pointed questions when shown a photo of Alexander's body lying crumpled in the bottom of the stall shower.

After a short pause, Martinez asked dryly, "Were you crying when you were shooting him?"

"I don't remember," Arias moaned.

"Were you crying when you stabbed him?" he said. "How about when you slashed his throat?"

"I don't remember, I don't know."

Martinez pressed on, "You're the one that did this right? And lied about all this right?"

"Yes."

"So then take a look at it," he barked.

Arias did not answer Martinez's question, crying into her hands instead. The judge, after a moment, called for the lunch recess to take a break from the testimony. Arias' attorney walked over and consoled her, telling her to "take a moment."

Until that moment, Arias had given vague answers to Martinez as he asked about the hours leading up to the murder. Arias, 32, has testified that she drove to Alexander's house on June 4, 2008, for a sexual liaison, that she had sex with Alexander and the pair took nude photos before an explosive confrontation ended with her killing him. She claims she doesn't remember stabbing Alexander, but insists it was in self-defense.

Martinez questioned her claims, asking exactly what they argued about and who encouraged whom to take the nude photos. He pointed out that Arias told Detective Esteban Flores of the Mesa police department that she had to convince Alexander to take the nude photos in the shower, but that she testified on the stand that Alexander had wanted them.

Quantum skyfall puts Einstein's gravity to the test

DIVIDING a falling cloud of frozen atoms sounds like an exotic weather experiment. In fact, it's the latest way to probe whether tiny objects obey Einstein's theory of general relativity, our leading explanation for gravity.

General relativity is based on the equivalence principle, which says that in free fall, all objects fall at the same rate, whatever their mass, provided the only force at work is gravity. That has been proven for large objects: legend has it that Galileo did it first by dropping various balls from the Tower of Pisa. Whether equivalence holds at quantum scales, where gravity's effects are not well understood, isn't clear. Figuring it out could help create a quantum theory of gravity, one of the biggest goals of modern physics.

Creating a quantum equivalent of Galileo's test isn't easy. In 2010 a team led by Ernst Rasel of the University of Hannover in Germany monitored a quantum object in free fall, by tossing a Bose-Einstein condensate (BEC) – a cloud of chilled atoms that behaves as a single quantum object and so is both particle and wave – down a 110-metre tall tower. Now they have split and recombined the wave – all before the BEC, made of rubidium atoms, reached the bottom. This produces an interference pattern that records the path of the falling atoms and can be used to calculate their acceleration (Physical Review Letters, doi.org/km6). The next step is to do the same experiment on a different kind of atom, with a different mass, to see if the equivalence principle holds.

The BEC can only be split for 100 milliseconds in the tower before hitting the bottom, so to allow tiny differences between the atom types to emerge, the work must be repeated in space, where the waves can be split for longer. By showing that a matter-wave can be split and recombined while falling, Rasel's result is a "major step" towards the space version, says Charles Wang of the University of Aberdeen, UK.

New SDPC mark for cigarettes from 1 March

SINGAPORE: From 1 March, cigarettes sold in Singapore which do not bear the new Singapore Duty-Paid Cigarette (SDPC) mark will be deemed duty-unpaid and illegal.

The new SDPC mark features a series of vertical bars around the cigarette stick.

The Singapore Customs said this allows enforcement officers and the public to easily differentiate duty-paid cigarettes from duty-unpaid or contraband cigarettes.

This measure will also enhance the effectiveness of the anti-contraband cigarette operations that Singapore Customs conducts across the island to curb the selling, buying and possession of contraband cigarettes.

To give manufacturers and retailers sufficient time to phase in the new SDPC mark, cigarettes bearing the new SDPC mark were allowed to be sold from 1 December 2012.

Travellers who bring in cigarettes from overseas for their own consumption are required to declare them at the Customs Red Channel for payment of duty and Goods and Services Tax (GST).

And they are advised to keep the receipt issued by Singapore Customs as proof of payment of duty and GST.

Those who buy, sell, deliver, store, keep, possess or deal with duty-unpaid goods face stiff penalties.

They could be fined up to 40 times the amount of duty evaded and jailed for up to six years.

Members of the public with information on smuggling activities or evasion of Customs duty or GST should contact Singapore Customs on its hotline 1800-2330000 or email customs_intelligence@customs.gov.sg.

Firefox and Tizen make a move for Android

Likely by Samsung's design, the Tizen OS looks reminiscent of Android.

(Credit:
CBS Interactive)

Alongside a myriad of new tablets and phones, Mobile World Congress 2013 also gave us our first real look at Mozilla's Firefox OS and the Samsung and Intel collaboration, Tizen OS.

While
Android might dominate the smartphone landscape today, it's only five years old. I can recall plenty of headlines in 2007 and 2008 that doubted whether there was room for yet another player in the space. At that time, RIM was a powerhouse, the iPhone was brand new, Palm's WebOS was in development, and Microsoft's Windows Mobile was slipping into obscurity.

My, how things have changed. Now the question is, it can happen again? Will
Firefox OS or Tizen OS impact Android or the smartphone landscape?

Cutting a piece of the smartphone pie
I predict that both will find success in developing markets and could even prove to be a bee in the Microsoft Windows Phone 8 bonnet. In fact, the definition of success could be interpreted differently for those involved. With smartphone activations rising all the time, even a small piece of the pie might be considered tasty.

I'm not entirely sure how Mozilla plans to monetize its open-source platform; Mozilla doesn't have search and mobile advertising to fall back on. Nevertheless, there are at least 18 handset makers and carriers who have pledged support for it. Really, who could fault any company for at least sampling the new goods?

There are already four such phones on the way -- the Alcatel One Touch Fire, the ZTE Open, the Geeksphone Keon, and the Geeksphone Peak -- and, I suspect, a handful more before the year is out. As of now, these devices are nowhere near as powerful as today's typical Android but that may not matter to the average consumer. We shouldn't expect much Firefox OS in the United States, though it's possible the bigger players are taking a "wait and see" approach.

LG also did a bit of hedging this week when it added its name to Mozilla's list of partners. LG even gave WebOS a new lease on life when it announced a licensing deal for the nearly-dead platform. Currently offering a number of Google TV sets, it's unclear how WebOS fits into the big scheme of things. Though I guess that it can't hurt to try new things every once in a while.

Alcatel's Firefox OS phone

Even so, I get the feeling that for now LG's bread is buttered by Google and that Firefox OS may be employed on devices released in secondary markets. Based on its diverse Mobile World Congress announcements, LG has a lot of Android momentum right now so I don't expect the company to change things up too much.

Samsung plays the field

Samsung, for its part, seems to be doing a little bit of everything these days. It introduced the Galaxy Note 8 in Barcelona, but it saved the reveal of the Galaxy S4 for an exclusive event on March 14. And though the company told CNET that it would pass on Firefox, it also said that it would be the first manufacturer to sell a Tizen phone come July. What about Bada, you ask? Well, a Korean news outlet said that Sammy would fold its own Bada OS into Tizen.

The first images of Tizen OS are reminiscent of Android, most likely due to Samsung. In fact, it wouldn't surprise me if future Galaxy experiences looked less like Android and more like Samsung. Should Samsung find success with the platform it may be possible to peel off a few Android users who have grown to use services such as Media Hub. In the big scheme of things, I imagine Samsung will create its own experience that looks the same on Android and Tizen.

It's too early in the game to forecast whether Tizen will impact its Android efforts, but whether Tizen makes it to the United States will make a big difference. While the platform has already drawn support from carriers around the globe, only Sprint has expressed interest for the U.S. market. And carriers aside, I'm more anxious to see which OEMs consider Tizen. It's hard to imagine a company like HTC, LG, or Sony, willing to use a platform created by a competitor.

Tizen OS gets early walkthrough in hands-on video

What's more, Samsung's new Knox is another signal that much attention is being paid to a broader consumer experience. Its bring-your-own-device (BYOD) solution would work well anyone who wants to want to use the same phone for work and personal use. Available for Android today, the feature might be available with other OSes like Tizen down the road. If that happens, Samsung would no doubt continue as one of Google's strongest Android partners, but the two companies may dance a little less frequently.

What's next?

Looking ahead, we may be in for more land grabs as hardware makers acquire software companies. We've seen this over the last few years with Apple, HTC, Samsung, and others. We've also seen jockeying from Amazon, Google, and other companies who scoop up services and apps. While some of these moves happen quietly and without much consequence, others are more overt and telling. One thing seems certain: nobody feels safe in this space. Rather, no one should feel safe.

In the short term, Firefox OS and Tizen will build a bit of steam; however, don't look for either to overtake RIM (especially following the launch of BlackBerry 10) or Windows Phone soon. And don't event think about a threat to iOS or Android. But then again, the growth of smartphone use in emerging markets is creating more competition. Android, after all, certainly surpassed the expectations of its early naysayers.

I am only too pleased that both of these new platforms are open-source as that should lead to more innovation. Here's to hoping that Android and iOS get some stiff competition in the future. Who doesn't want a less expensive smartphone that does incredibly cool stuff?

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."

Arias Prosecutor Too Combative, Experts Say

He has barked, yelled, been sarcastic and demanded answers from accused murderer Jodi Arias this week.

And in doing so, prosecutor Juan Martinez and his aggressive antics may be turning off the jury he is hoping to convince that Arias killed her ex-boyfriend Travis Alexander in June 2008, experts told ABCNews.com today.

"Martinez is his own worst enemy," Mel McDonald, a prominent Phoenix defense attorney and former judge, told ABC News. "He takes it to the point where it's ad nauseam. You have difficulty recognizing when he's driving the point home because he's always angry and pushy and pacing around the courtroom. He loses the effectiveness, rather than build it up."

"He's like a rabid dog and believes you've got to go to everybody's throat," he said.

"If they convict her and give her death, they do it in spite of Juan, not because of him," McDonald added.

Martinez's needling style was on display again today as he pestered Arias to admit that she willingly participated in kinky sex with Alexander, though she previously testified that she only succumbed to his erotic fantasies to please him.

Arias, now 32, and Alexander, who was 27 at the time of his death, dated for a year and continued to sleep together for another year following their break-up.

Arias drove to his house in Mesa, Ariz., in June 2008, had sex with him, they took nude photos together and she killed him in his shower. She claims it was in self-defense. If convicted, Arias could face the death penalty.

Martinez also attempted to point out inconsistencies in her story of the killing, bickering with her over details about her journey from Yreka, Calif., to Mesa, Ariz., including why she borrowed gas cans from an ex-boyfriend, when she allegedly took naps and got lost while driving, and why she spontaneously decided to visit Alexander at his home in Mesa for a sexual liaison.

"I want to know what you're talking about," Arias said to Martinez at one point.

"No, I'm asking you," he yelled.

Later, he bellowed, "Am I asking you if you're telling the truth?"

"I don't know," Arias said, firing back at him. "Are you?"

During three days of cross examining Arias this week, Martinez has spent hours going back and forth with the defendant over word choice, her memory, and her answers to his questions.

"Everyone who takes witness stand for defense is an enemy," McDonald said. "He prides himself on being able to work by rarely referring to his notes, but what he's giving up in that is that there's so much time he wastes on stupid comments. A lot of what I've heard is utterly objectionable."

Martinez's behavior has spurred frequent objections of "witness badgering" from Arias' attorney Kirk Nurmi, who at one point Tuesday stood up in court and appealed to the judge to have a conference with all of the attorneys before questioning continued. Judge Sherry Stephens at one point admonished Martinez and Arias for speaking over one another.

Andy Hill, a former spokesperson for the Phoenix police department, and Steven Pitt, a forensic psychiatrist who has testified as an expert witness at many trials in the Phoenix area, both said that despite his aggressive style, Martinez would likely succeed in obtaining a guilty verdict.

"When it comes to cross examination, one size does not fit all," said Pitt. "But if you set aside the incessant sparring, what the prosecutor I believe is effectively doing is pointing out the various inconsistencies in the defendant's version of events."

Yahoo! fuels fresh debate on telecommuting

WASHINGTON: Telecommuting, a growing trend in the US workplace, is coming under fresh scrutiny following news that Yahoo! is curbing the practice.

The trend of working from home has been gaining steam for decades, as part of a workplace evolution which allows greater family-work balance and saves energy and commuting costs.

An internal Yahoo! memo from chief executive Marissa Meyer posted this week by the Wall Street Journal said employees will be required to come to their offices to "feel the energy and buzz" of the workplace.

"Speed and quality are often sacrificed when we work from home. We need to be one Yahoo!, and that starts with physically being together," according to the report.

Asked about the memo, a Yahoo! spokesman said Tuesday, "We don't discuss internal matters," but essentially confirmed the news by saying: "This isn't a broad industry view on working from home -- this is about what is right for Yahoo!, right now."

The shift counters the overall trend: some 53 per cent of US employers offered flexible work options in 2012, according to the Society for Human Resource Management. That compares with 48 per cent in 2007.

A 2011 report by the US Labor Department found 24 per cent of employed Americans reporting that they work at least some hours at home each week.

The trend is particularly noticeable in IT firms, where companies take advantage of technology to have virtual access to what they would have at the office.

Cisco Systems, which develops virtual private networks for remote access, said 40 per cent of its employees are not in the same city as their manager, and the average employee telecommutes two days a week.

IBM, another strong telework advocate, said 29 per cent of its 128,000 employees participate in a flex-work or work at home program, and that in 2011, in the US alone, this saved 6.4 million gallons of fuel and avoided more than 50,000 metric tons of carbon emissions.

The move by Yahoo! "goes against the grain of where a lot of organizations are going today," said Cindy Auten, general manager of Mobile Work Exchange, a public-private partnership that promotes telework.

"This is especially important in the tech industry; they are focused on recruiting and retaining the best and brightest."

Auten said telework is "a huge recruitment and retention tool," seen as a near necessity at some firms now, with the option offered in 85 per cent of the employers rated as "best places to work."

She said telecommuting often improves productivity, but that in cases where it fails, "it may uncover other weaknesses" in an organization.

The Yahoo! decision drew criticism from others, including Virgin Group founder Richard Branson, who said in a tweet: "Perplexed by Yahoo! stopping remote working. Give people the freedom of where to work & they will excel."

Kelly Ann Collins, a Washington marketing consultant who blogs on work and family issues, called the Yahoo! move confusing.

"High-tech companies like Yahoo! that are completely digital have the ability to make the lives of their employees so much better," she wrote.

"Telecommuting is not only efficient, it is better for team morale and employee retention. It makes for happier employees that (actually like to) produce top-notch work."

But some analysts say Yahoo!'s move could be positive, even if it drives away those seeking a more flexible environment.

"Yahoo! is in a creative innovation race and they need to get back to their roots," said John Challenger, chief executive of the consultancy Challenger, Gray & Christmas.

"There are great benefits to telecommuting, and there are more companies that need to do more telecommuting, but (Yahoo!) is a case where they are seeking to pull themselves out from a position where they have been behind the curve."

Even before the Yahoo! news, some data suggested telecommuting was not the panacea it was cracked up to be.

The Labor Department report found that telecommuters often ended up working more hours than if they had come into the office, effectively doing overtime work without compensation.

"The ability of employees to work at home may actually allow employers to raise expectations for work availability during evenings and weekends and foster longer workdays and workweeks," the report said.

But Challenger said Yahoo! will not be able to turn back the clock completely, and that some employees are likely to do some of their work from home, despite the new policy,

"Some people have always worked from home," he said. "And now technology allows them to work on the weekends, at night or on vacation. There is no boundary between work and home anymore."

Samsung Galaxy S4 rumor roundup

The next next big thing is almost here?

Editors' note: This piece was originally posted on January 24, 2013. We'll continuously update the roundup until the device's official launch. Please let us know if we missed any rumors ourselves.

Considering the popularity and success of the Samsung Galaxy S3, it's understandable that whispers of its successor (presumably called the Galaxy S4) are circulating. From iffy launch dates to spec upgrades, CNET tracks all the talk and rounds up the latest GS4 rumors here.

February 25, 2013
The invitations are out
Samsung issued the formal invitations for New York
Galaxy S4 reveal. As expected, it will take place March 14, at 7 p.m. ET. It also will be live-streamed on Samsung Mobile's YouTube page.

Visa on the Galaxy S4
Samsung said it would use Visa's PayWave mobile payment applet in its future devices and partner with Visa to make it easier for customers to tie their Samsung handsets to a financial institution and Visa account. While not referenced specifically, the Galaxy S4 will be the flagship product for Visa's program, according to a person familiar with the partnership.

February 24, 2013
March 14 will be the big day
At Mobile World Congress in Barcelona, Spain Samsung confirmed that it would host a "Samsung Unpacked" event in New York on March 14 where it would unveil the Galaxy S4. Samsung told CNET that it is also was considering embedding its new security software, Knox, into the handset.

February 18, 2013
Or maybe it's March 14
Russian analyst and rumor-meister Eldar Murtazin told Sammobile that the Galaxy S4 will come on March 14, which is one day earlier than a previous rumor suggested. Sammobile also speculated that Galaxy S4's specs would include an Exynos 5 Octa (8-Core) CPU, Mali-T678 (8-Core) GPU, 4.99-inch SuperAMOLED display, 2GB of RAM, a 13-megapixel rear camera with 1080p video capability, 2-megapixel front facing camera, and
Android 4.2.2 Jelly Bean.

February 6, 2013
March 15 presser in the works
Doubling down with its April sale date prediction, SamMobile is reporting that Samsung will hold a March 15 press event to unveil the handset. Citing a "trusted insider," the site said it should expect a presser invitation after MWC finishes. Here's hoping -- because there's nothing sadder than waiting for an invite to the coolest party of the year and staring down an empty mailbox instead.

Maybe we'll see it in March
Throwing his hat into the "March debut" ring is an analyst from Canaccord Genuity named T. Michael Walkley. He predicts that Samsung will launch the handset during that month to extand its market share lead during that quarter.

February 1, 2013
Scratch that September rumor; you won't see it at MWC after all
According to a source who spoke to CNET, it looks like the Galaxy S4 will be absent at Mobile World Congress this year. Instead, the company will probably put on its own event just for the device, similar to what it did last year with the S3 in May.

January 23, 2013
You may get your hands on the GS4 in April
It's always interesting when rumors start ball-parking a release date, but SamMobile does one better and gives an exact date: Tax Day. Not only did the outlet report its launch day will be on April 15, it also said the phone will have a larger 2,600mAh battery.

December 6, 2012
Superstrong, bendy display?
Reuters reported that the new Galaxy phone may be equipped with a flexible, ultra-tough touch screen. Although this sounds far out, we've seen firsthand what Samsung can do with its flexible Youm display. That's not to say it'll definitely come to the market any time soon, but it is evident that the company is working with such technology.

December 4, 2012
It will get plenty of spec bumps

A History of Balloon Crashes

A hot-air balloon exploded in Egypt yesterday as it carried 19 people over ancient ruins near Luxor. The cause is believed to be a torn gas hose. In Egypt as in many other countries, balloon rides are a popular way to sightsee. (Read about unmanned flight in National Geographic magazine.)

The sport of hot-air ballooning dates to 1783, when a French balloon took to the skies with a sheep, a rooster, and a duck. Apparently, they landed safely. But throughout the history of the sport, there have been tragedies like the one in Egypt. (See pictures of personal-flight technology.)

1785: Pioneering balloonist Jean-Francois Pilatre de Rozier and pilot Pierre Romain died when their balloon caught fire, possibly from a stray spark, and crashed during an attempt to cross the English Channel. They were the first to die in a balloon crash.

1923: Five balloonists participating in the Gordon Bennett Cup, a multi-day race that dates to 1906, were killed when lightning struck their balloons.

1924: Meteorologist C. LeRoy Meisinger and U.S. Army balloonist James T. Neely died after a lightning strike. They had set off from Scott Field in Illinois during a storm to study air pressure. Popular Mechanics dubbed them "martyrs of science."

1995: Tragedy strikes the Gordon Bennett Cup again. Belarusian forces shot down one of three balloons that drifted into their airspace from Poland. The two Americans on board died. The other balloonists were detained and fined for entering Belarus without a visa. (Read about modern explorers who take to the skies.)

1989: Two hot air balloons collided during a sightseeing trip near Alice Springs, Australia. One balloon crashed to the ground killing all 13 people on board. The pilot of the other balloon was sentenced to a two-year prison term for "committing a dangerous act." Until today, this was considered the most deadly balloon accident.

2012: A balloon hit a power line and caught fire in New Zealand, killing all 11 on board. Investigators later determined that the pilot was not licensed to fly and had not taken  proper safety measures during the crash, like triggering the balloon's parachute and deflation system.

2012: A sightseeing balloon carrying 32 people crashed and caught fire during a thunderstorm in the Ljubljana Marshes in Slovenia. Six died; many other passengers were injured.
