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.

China village defies officials to demand democracy

SHANGPU, China: Villagers in southern China were locked in a stand-off with authorities on Sunday and were demanding democratic polls after a violent clash with thugs linked to a local official over a land transfer.

Just over a week ago, residents of Shangpu in Guangdong province fought with scores of attackers whom they claimed were sent by the village communist party chief and a business tycoon after they protested against a land deal.

Police are blockading the settlement to outsiders while residents refuse to let officials inside, days before the annual meeting of the country's legislature, the National People's Congress (NPC).

The situation recalls a similar episode in Wukan, also in Guangdong and around 100 kilometres (62 miles) from Shangpu, which made headlines worldwide 15 months ago.

At the main entrance of the village of 3,000 people, 40 police and officials stood guard, barring outside vehicles from entering. Not far away, a cloth banner read: "Strongly request legal, democratic elections."

Shangpu's two-storey houses and low-slung family-run workshops are surrounded by fields awaiting spring planting. But the main street is lined with the wrecks of cars damaged in the clash, with glass and metal littering the ground.

Residents said they should have the right to vote both for the leader who represents them and on whether to approve a controversial proposal to transform rice fields into an industrial zone.

"This should be decided by a vote by villagers," said one of the protest leaders, adding: "The village chief should represent our interests, but he doesn't."

Locals fear that once the NPC -- which starts on Tuesday -- ends, authorities will move in with force.

Chinese leaders have repeatedly ruled out Western-style democracy for the country.

"For the purpose of maintaining stability, they (authorities) don't want to use forceful measures before the meetings," another villager said. "We are afraid of them coming back."

The unidentified attackers, some of whom wore orange hard hats and red armbands, drove into the village and turned on residents with shovels and other weapons.

Villagers drove the interlopers off by hitting them with bamboo poles and throwing bricks from a nearby construction site, according to first-hand accounts and video of the incident provided to AFP.

They said they then vented their fury on the attackers' cars, overturning and smashing as many as 29 vehicles.

Residents claimed some of the group had knives and a gun. A video showed a man firing a handgun into the air and villagers said he was a plainclothes police officer trying to intercede. At least eight villagers were injured.

In Wukan in late 2011, a protest by residents against a land grab by local officials accused of corruption escalated after one of their leaders died in police custody.

Villagers barricaded roads and faced off against security forces for 10 days, until authorities backed down and promised them rare concessions. Residents were later allowed to hold open village elections -- a first in Wukan.

The people of Shangpu had heard of Wukan indirectly, and had similar demands: free elections for their leader.

They claim the current village chief Li Baoyu, who is also the party head, was foisted on them by higher authorities.

Residents allege Li fraudulently obtained signatures to support the transfer of 33 hectares (82 acres) of farmland to the Wanfeng Investment Co, backed by businessman Wu Guicun, to be used for factories producing electrical cables.

The village's ruling committee will receive compensation based on the yield of rice that would have been planted on the land. But residents fear they themselves will not be paid and say the compensation does not reflect the true value.

"Village cadres have illegally dealt in land and leased land at a low price," they said in a petition to higher officials.

In the government's only official statement on the case, Jiexi county, which administers the village, pledged to pursue those responsible for the attack and bring criminal prosecutions.

No one from Wanfeng Investment Co could be reached for comment.

LG notches 10M worldwide sales of LTE-enabled smartphones

LG Electronics announced today it has sold more than 10 million LTE-capable smartphones worldwide as the company grapples with dwindling market share.

The milestone comes a little more than six months after the company announced it had surpassed 5 million sales of LTE-enabled phones.

"Aggressive pushing forward with 4G LTE technology allows LG satisfy the needs of consumers and is a huge factor in our growing success in global LTE smartphone sales," LG CEO Jong-seok Park said in statement. "Having established ourselves as a major industry player, we will continue to expand our footprint in the global LTE market with a wider range of differentiated, high quality LTE smartphones."

LG said it hopes to double its LTE smartphone presence in 2013 as LTE smartphone shipment growth is expected to triple. Strategy Analytics said in December that its research indicated global LTE smartphone shipments would hit 275 million this year.

The company attributed its explosive growth in the segment to its expansion last year into markets such as the United States, Japan, Germany, and South Korea. Recent rollouts of the LG Optimus G in more than 50 additional countries also contributed to the milestone.

As impressive as the sales figure is, LG continues to lose ground in the LTE market, according to research firm Strategy Analytics. In the third quarter of 2012, LG's market share fell to 9 percent from 15 percent in the previous quarter. Samsung remained the market leader even though its share fell from 51 percent to 40 percent. Apple brought in 26.7 percent for second place.

The announcement comes on the heels of LG's overhaul of its
Android product line at the Mobile World Congress last month in Barcelona, Spain. LG says it is targeting the spectrum of LTE customers, with its G series for deep-pocketed early adopters, the F series with the mission of "4G LTE for everyone," the lower-end L series, and the Vu
tablets.

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.

Man's Body Recovery Effort Ends; Sinkhole 'Unstable'

Authorities have discontinued the rescue effort for a Florida man who was swallowed by a sinkhole when his home's foundation collapsed and said it is unlikely his body will ever be recovered.

"We feel we have done everything we can," Hillsborough County administrator Mike Merrell said at a news conference this afternoon. "At this point, it's not possible to recover the body."

Merell said officials would bring in heavy equipment to begin demolishing the home on Sunday.

"We're dealing with a very unusual sinkhole," he said. "It's very deep. It's very wide. It's very unstable."

Jeff Bush was in his bedroom when a sinkhole opened up and trapped him underneath his home at 11 p.m. Thursday.

Two homes next door to Bush's residence were evacuated today after authorities said they had been compromised by the growing sinkhole.

With the assistance of rescuers, the homeowners will be allowed to enter their home for only 30 minutes to gather valuables, authorities said.

Rescuers returned to the site in Seffner, Fla., early this morning to conduct further testing, but decided it was too dangerous for the family initially affected by the sinkhole to enter their home, which was declared condemned.

While the sinkhole was initially estimated to be 15 feet deep on Thursday night, the chasm has continued to grow. Officials now estimate it measures 30 feet across and is up to 100 feet deep.

The Hillsborough County Fire Rescue has set up a relief fund for all families affected by the growing sink hole.

Rescue operations were halted Friday night after it became too dangerous to approach the home.

Bill Bracken, an engineer with Hillsborough County Urban Search and Rescue team said the house "should have collapsed by now, so it's amazing that it hasn't."

RELATED: Florida Man Swallowed by Sinkhole: Conditions Too Unstable to Approach

Using ground penetrating radar, rescuers have found a large amount of water beneath the house, making conditions even more dangerous for them to continue the search for Bush.

Hillsborough County lies in what is known as Florida's "Sinkhole Alley." More than 500 sinkholes have been reported in the area since 1954, according to the state's environmental agency.

Meanwhile, Bush's brother, Jeremy Bush, is still reeling from Thursday night.

Jeremy Bush had to be rescued by a first responder after jumping into the hole in an attempt to rescue his brother when the home's concrete floor collapsed, but said he couldn't find him.

"I just started digging and started digging and started digging, and the cops showed up and pulled me out of the hole and told me the floor's still falling in," he said.

"These are everyday working people, they're good people," said Deputy Douglas Duvall of the Hillsborough County sheriff's office. "And this was so unexpected, and they're still, you know, probably facing the reality that this is happening."

3 dead in new Bangladesh war crimes protests: police

CHITTAGONG, Bangladesh: Bangladesh police on Saturday opened fire at Islamists protesting the conviction for war crimes of one of their leaders, killing three people outside the port city of Chittagong.

The deaths brought the total number killed since a war crimes tribunal delivered its first verdict on January 21 to at least 56, according to police figures.

The number includes 40 who have died in the last three days, since Jamaat-e-Islami party vice president Delwar Hossain Sayedee was sentenced to death, police said.

Sayedee was found guilty on Thursday of murder, religious persecution and rape during the 1971 independence war, triggering violent clashes between rampaging Jamaat supporters and police across the country.

The 73-year-old firebrand preacher was the third person to be convicted by the war crimes tribunal, whose verdicts have been met by outrage from Islamists.

The Islamists say the process is more about settling scores than delivering justice.

The latest violence came a day after the United States called for calm in the impoverished South Asian nation.

"While engaging in a peaceful protest is a fundamental democratic right, we believe violence is never the answer," US State Department deputy acting spokesman Patrick Ventrell told reporters in Washington.

But he stressed the United States believes "it is important to bring justice to those who have committed war crimes and atrocities" while ensuring that the trials be "free, fair, transparent".

In the new clashes, police said they fired live rounds after hundreds of student activists of Jamaat barricaded a key highway and attacked officers with stones and sticks as they tried to clear the road.

"We were forced to open fire. Three people were killed in the clashes," senior Chittagong police official Rabiul Islam told AFP, adding 10 people, including policemen, were wounded.

The war crimes trials of a dozen Jamaat and main opposition Bangladesh Nationalist Party (BNP) leaders have opened old wounds and divided the nation.

The opposition has accused the government of staging a witchhunt.

The government, which says the war claimed three million lives, rejects the claims and accuses Jamaat leaders of being part of pro-Pakistani militias blamed for much of the carnage during the 1971 independence war.

Independent estimates put the death toll from the war in which Bangladesh won its independence from Pakistan at a much lower figure of 300,000 to 500,000.

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.

Space gold rush should not be a free-for-all

We need a consensus on regulations surrounding space mining if it’s to enrich us all

EVER since we took our first steps out of Africa, human exploration has been driven by the desire to secure resources. Now our attention is turning to space.

The motivation for deep-space travel is shifting from discovery to economics. The past year has seen a flurry of proposals aimed at bringing celestial riches down to Earth. No doubt this will make a few billionaires even wealthier, but we all stand to gain: the mineral bounty and spin-off technologies could enrich us all.

But before the miners start firing up their rockets, we should pause for thought. At first glance, space mining seems to sidestep most environmental concerns: there is (probably!) no life on asteroids, and thus no habitats to trash. But its consequences – both here on Earth and in space – merit careful consideration.

Part of this is about principles. Some will argue that space's "magnificent desolation" is not ours to despoil, just as they argue that our own planet's poles should remain pristine. Others will suggest that glutting ourselves on space's riches is not an acceptable alternative to developing more sustainable ways of earthly life.

History suggests that those will be hard lines to hold, and it may be difficult to persuade the public that such barren environments are worth preserving. After all, they exist in vast abundance, and even fewer people will experience them than have walked through Antarctica's icy landscapes.

There's also the emerging off-world economy to consider. The resources that are valuable in orbit and beyond may be very different to those we prize on Earth (see "Space miners hope to build first off-Earth economy"). Questions of their stewardship have barely been broached – and the relevant legal and regulatory framework is fragmentary, to put it mildly.

Space miners, like their earthly counterparts, are often reluctant to engage with such questions. One speaker at last week's space-mining forum in Sydney, Australia, concluded with a plea that regulation should be avoided. But miners have much to gain from a broad agreement on the for-profit exploitation of space. Without consensus, claims will be disputed, investments risky, and the gains made insecure. It is in all of our long-term interests to seek one out.

Bertelsmann buys out KKR in music rights business BMG

FRANKFURT: German media giant Bertelsmann said Friday it has agreed to buy out the US investment fund KKR in their jointly-owned music rights management company BMG for an undisclosed sum.

Bertelsmann said in a statement it will acquire the 51-percent stake that KKR has held in BMG since 2009, finally bringing the unit back under full ownership.

BMG was originally set up in 2008 and KKR acquired its 51-percent stake in 2009.

According to the Financial Times last week, the estimated cost of the deal is around 500 million euros ($654 million).

The deal is still subject to regulatory approval, but is scheduled to close "during the first half of this year," the statement said.

Bertelsmann said BMG manages the rights to more than one million songs, including works by such artists as Bruno Mars, Duran Duran, Gossip, Johnny Cash, and Will.i.am.

It also represents the master rights -- composition and recording -- of artists such as Brian Ferry, Nena and Anastacia.

"This is a great day for Bertelsmann. We are bringing the music home to our group. We are happy to have BMG as our own company again," said Bertelsmann chief executive Thomas Rabe.

Rabe said KKR had been a good partner, but taking full ownership of BMG was "an important step in putting Bertelsmann's growth strategy into practice," Rabe said.

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."

Sequestration: Surrender is in the Air

The budget ax is about to fall, and there's little lawmakers in Washington are doing to stop it.

Despite a parade of dire warnings from the White House, an $85 billion package of deep automatic spending cuts appears poised to take effect at the stroke of midnight on Friday.

The cuts – known in Washington-speak as the sequester – will hit every federal budget, from defense to education, and even the president's own staff.

On Capitol Hill, Senate Democrats and Republicans each staged votes Thursday aimed at substituting the indiscriminate across-the-board cuts with more sensible ones. Democrats also called for including new tax revenue in the mix. Both measures failed.

Lleaders on both sides publicly conceded that the effort was largely for show, with little chance the opposing chamber would embrace the other's plan. They will discuss their differences with President Obama at the White House on Friday.

"It isn't a plan at all, it's a gimmick," Senate Minority Leader Mitch McConnell, R-Ky., said today of the Democrats' legislation.

"Republicans call the plan flexibility" in how the cuts are made, said Senate Majority Leader Harry Reid. "Let's call it what it is. It is a punt."

The budget crisis is the product of a longstanding failure of Congress and the White House to compromise on plans for deficit reduction. The sequester itself, enacted in late 2011, was intended to be so unpalatable as to help force a deal.

Republicans and Democrats, however, remain gridlocked over the issue of taxes.

Obama has mandated that any steps to offset the automatic cuts must include new tax revenue through the elimination of loopholes and deductions. House Speaker John Boehner and the GOP insist the approach should be spending cuts-only, modifying the package to make it more reasonable.

"Do we want to close loopholes? We sure do. But if we are going to do tax reform, it should focus on creating jobs, not funding more government," House Speaker John Boehner said, explaining his opposition to Obama's plan.

Boehner, McConnell, Reid and House Minority Leader Nancy Pelosi will huddle with Obama at the White House on Friday for the first face-to-face meeting of the group this year.

"There are no preconditions to a meeting like this," White House spokesman Jay Carney said today. "The immediate purpose of the meeting is to discuss the imminent sequester deadline and to avert it."

Even if the leaders reach a deal, there's almost no chance a compromise could be enacted before the deadline. Lawmakers are expected to recess later today for a long weekend in their districts.

What will be the short-term impact of the automatic cuts?

Officials say it will be a gradual, "rolling impact" with limited visible impact across the country in the first few weeks that the cuts are allowed to stand.

Over the long term, however, the Congressional Budget Office and independent economic analysts have warned sequester could lead to economic contraction and possibly a recession.

"This is going to be a big hit on the economy," Obama said Wednesday night.

"It means that you have fewer customers with money in their pockets ready to buy your goods and services. It means that the global economy will be weaker," he said. "And the worst part of it is, it's entirely unnecessary."

Both sides say that if the cuts take effect, the next best chance for a resolution could come next month when the parties need to enact a new federal budget. Government funding runs out on March 27, raising the specter of a federal shutdown if they still can't reach a deal.

"As we anticipate an across-the-board budget cuts across our land, we still expect to see your goodness prevail, O God, " Senate Chaplain Barry Black prayed on the Senate floor this morning, "and save us from ourselves."

Bacteria defeat antibiotics they have never met before

BACTERIA that resist antibiotics are a growing problem worldwide, but one we thought we could limit or even reverse by better control of the drugs. This may be a forlorn hope: some bacteria that have never seen an antibiotic can evolve resistance, and even thrive on it.

Bacteria usually become resistant if they are exposed to drug levels too low to kill them off, but high enough to favour the survival of resistant mutants. Such resistance is growing and could make TB and other diseases untreatable again.

The prevailing notion was that bacteria acquire and maintain resistance genes at a cost. So by carefully controlling antibiotics, resistance should not emerge by itself – and should die out as soon as the antibiotic is withdrawn and resistance is no longer an advantage.

Maybe not. Olivier Tenaillon at Denis Diderot University, Paris, and colleagues were studying bacterial evolution by exposing Escherichia coli to high temperatures and little food. Unexpectedly, some bacteria spontaneously became resistant to the antibiotic rifampicin, even though they had never encountered it. The mutation that helped them deal with environmental stress just happened to confer resistance to the drug, used to treat TB and meningitis (BMC Evolutionary Biology, doi.org/kks).

"Our work suggests that selective pressure other than antibiotics may drive resistance," says Tenaillon.

Moreover, bacteria with the mutation grew 20 per cent faster than otherwise-identical bacteria – a first for a resistance mutation.

It only had this beneficial effect in the heat-adapted strain, says Arjan de Visser of Wageningen University in the Netherlands, who was not involved in the study. But, he adds, "these results are a cautionary tale for the use of antibiotics – resistance may come without costs [to bacteria]".

Sony sells Tokyo office building for US$1.2b

TOKYO: Sony said on Thursday it has sold one of its main buildings in Tokyo for US$1.2 billion as the embattled Japanese electronics giant offloads assets to help repair its tattered balance sheet.

The news comes after the company in January announced the sale of its US headquarters in Manhattan for more than US$1.0 billion while this month it also sold part of its online medical services unit.

Sony said its had sold the 25-storey central Tokyo building, which houses its television unit, to Nippon Building Fund and an unnamed Japanese institutional investor for 111 billion yen (US$1.2 billion) and would earn it a profit of 41 billion yen.

"Sony is transforming its business portfolio and reorganising its assets in an effort to strengthen its corporate structure," the company said in a statement. "This sale was conducted as a part of this reorganisation."

Sony said it would remain in the central Tokyo building for five years under a leasing agreement.

Earlier this month, the firm said it would book a US$1.2-billion gain from selling part of an online medical services unit, as it eyes a full-year profit after four years in the red.

Sony has announced a massive corporate overhaul that includes thousands of job cuts, the sale of a chemical division and an investment in Olympus to tap the camera and medical equipment maker's strong foothold in the global market for endoscopes.

The maker of Bravia televisions and PlayStation games consoles lost 456.66 billion yen in the last fiscal year, but says it is on track for a 20-billion-yen net profit in the year to March.

Last week, Sony announced it would launch its PlayStation 4 system as it faces increasing competition from cheap -- or sometimes free -- downloadable video games for smartphones and tablets.

The company's hard times saw its stock value tumble below 1,000 yen a share last year, for the first time since the era of the Walkman.

The stock has since come back, with Sony shares up 3.56 per cent at 1,338 yen on Thursday in Tokyo.

Japan's electronics sector has suffered a myriad of problems, including a strong yen, slowing demand in key export markets, fierce competition especially in the struggling TV division and strategic mistakes.

The industry has been awash in huge losses and credit rating downgrades, with rival Sharp saying last year it would put up real estate as collateral for bank loans -- including its Osaka headquarters -- to stay afloat.

Viddy doubles length of clips, adds video enhancement tools

Viddy's new iOS app interface.

Social video startup video has released a new iOS app with a bevy of new features to help users enhance the videos they produce and stave off Twitter's upstart video-sharing app Vine.

Debuting this evening in Apple's App Store, the new app doubles the size of videos users can upload from 15 seconds to 30 seconds, as well as adding the Vine-like ability to pause recording to splice together segments into a single clip. The app also adds 15 new video filters, licensed music tracks from popular artists that can be added to videos, and stop-motion functionality that adjusts video frame rates.

Viddy, which is sometimes referred to as the Instagram of video, also social discovery tools to help users find and share videos that are important to them. The update adds a section with curated video categories and trending topics. A geo-centric feed spotlights videos from specific regions, while another feed focuses on user interests and preferences.

In another Twitter-like feature, Viddy will add a verified user program for celebrities, public figures, and company brands.

The new video comes in the wake of corporate upheaval at the Venice, Calif.-based startup. The company, which claims 40 million users, revealed earlier this week that it had laid off a dozen employees, or about a third of its work force. The cuts came less than a month after the firing of co-founder and CEO Brett O'Brien, who was rumored to have turned down a buyout offer from Twitter, which ended up buying Vine and launching its app last month.

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."

We need a piece of Mars to continue search for life

THERE'S no need to cry over spilt chemicals. Thanks to an accident inside one of its instruments, NASA's Curiosity rover has detected the presence of a substance called perchlorate in Martian soil (see "Curiosity's spills add thrills to the Mars life hunt").

Not exactly earth-shattering, you might think. But it adds a new twist to the most controversial chapter in Martian history: did the Viking landers detect life?

This is a question that has divided the Viking missions' researchers for almost three decades. One group has resolutely stuck to its guns that the landers detected signs of life. Equally adamant is a second group who say they absolutely did not – a view that has always been the official version of events.

The unexpected discovery of perchlorate supplies a legitimate reason to reopen the debate. Perchlorate is an oxidising agent that destroys organic molecules. Its presence could finally explain the disputed results.

The episode highlights another important issue. Curiosity is a sophisticated machine, but there is only so much soil chemistry we can do from millions of kilometres away. A sample return mission must be a priority.

Australian cyclone crossing Western Australian coast

SYDNEY: A tropical cyclone hit Australia's resource-rich northwest coast Wednesday, bringing winds of up to 165 kilometres (102 miles) an hour as it crossed the shore near the tiny community of Pardoo.

Severe tropical cyclone Rusty had been sitting offshore for several days, slowly intensifying as it edged towards the Pilbara coast and bringing heavy rain and gale-force winds to the iron ore region.

"It is in the process of crossing," Neil Bennett from Australia's Bureau of Meteorology told AFP just after 0700 GMT, adding it was too soon to say whether it had caused any damage.

"Wind gusts in excess of 165 kilometres an hour are in that area."

Bennett said the storm had been downgraded from a category 4 storm, just one notch short of the top category, to a category 3.

The bureau had expected Rusty to make landfall close to Port Hedland, 1,300 kilometres (800 miles) north of Perth, but Bennett said the major iron ore port appeared to have escaped the full brunt of the storm.

"It looks as if Hedland has dodged the bullet, so to speak, because the worst of the winds are away from Hedland," he said.

"Hedland though has been experiencing a constant period of gale-force winds for over 36 hours now. And that's unprecedented (for that area)."

While the storm has been downgraded, its eye has also contracted from being about 80 kilometres wide on Tuesday to about 50 kilometres by the time it crossed land.

Authorities had warned residents to move out of the storm's path or seek shelter. Resident Ian Badger said he was seeking refuge at the Pardoo Roadhouse, about 120 kilometres from Port Hedland.

"It's just a matter of hanging on," he told the Australian Broadcasting Corporation.

"The amount of water that's around is a bit worrying. The ground is very sodden, very soft. As soon as you get a get a bit of strong wind, trees start going over."

The weather bureau expects the cyclone to move slowly in a south-southeasterly direction, gradually downgrading to a category 1 storm by Thursday afternoon and a tropical low the following day.

Australia's major iron ore export ports have been shut for several days anticipating Rusty's approach. Hundreds of people have been forced to evacuate their homes in the sparsely populated but cyclone-prone area.

Global iron ore giants including BHP Billiton, Rio Tinto and Fortescue Metals Group have all shut down or scaled back operations due to the storm.

Why you should wait for the Samsung Galaxy S4

It was only about nine months ago that Samsung introduced its flagship Galaxy S3 to the world.

There's no question the device set a new standard for the high-end
Android smartphone. It has also been one of Samsung's hottest selling smartphones. And now it looks like Samsung is about to do it again with the
Galaxy S4, set for introduction March 14.

So what is a smartphone shopper to do? In this edition of Ask Maggie, I explain why, even if you still want to get the Samsung S3, it's still better to wait for the launch of the Galaxy S4. I also help another reader make sure her older Android device is really connecting to Wi-Fi instead of eating up her expensive data plan.

Buy the Samsung Galaxy S3 or wait for the Galaxy S4?

Dear Maggie,
I just realized I am eligible for a new two-year contract on AT&T. I have been considering getting a new Samsung Galaxy S3. But now I am wondering if I should just wait for the Samsung Galaxy S4. Are there any discounts on the Galaxy S3 now? Will there be discounts on that phone if I wait? Or will the new Galaxy S4 be so much better, I'll just want that one?

Thanks
Andrew

Dear Andrew,
The short answer to your question is to simply wait. If you aren't in dire need of a new smartphone right now, you should wait just a little while longer. This week Samsung sent out invitations to an event in New York City on March 14 where it will debut the new Galaxy S4. The device won't likely go on sale until April, but considering, it's already the end of February, that isn't too long to wait.

It's hard to say how the new Galaxy S4 will stack up against the Galaxy S3 since specifications haven't been released. But there have been plenty of rumors swirling around that give us an idea of what is likely coming. And there is no question that the Galaxy S4 will be an improvement over the S3.

For example, the Galaxy S4 is rumored to have an eight-core Exynos processor, a separate eight-core graphics processing unit, a 4.99-inch SuperAmoled display, 2GB of RAM, a 13-megapixel rear camera with 1080p video capability, a 2-megapixel front-facing camera, and the latest version of Android, known as 4.2.2 Jelly Bean.

My colleague Roger Cheng, who was in Barcelona, Spain, this week for Mobile World Congress, talked to Samsung execs there who said that the new Galaxy S4 may also sport Samsung's new security software, Knox.

These specs are an improvement over the Galaxy S3, which has a 4.8-inch screen and a 1.4GHz quad-core processor, 2GB of RAM and an 8-megapixel rear-facing camera.

This doesn't mean that you should not consider the Galaxy S3. In fact, regardless of what new specs for the new Galaxy S4 are, the Galaxy S3 is still a very good smartphone. And if you are on a budget, the Galaxy S3 could be a great fit for you.

That said, I still think you need to wait until the Galaxy S4 is closer to its launch or until after it launches. Why wait? That's when you are likely to see the best deals on the older Galaxy S3.

Right now, you can get discounts on the Galaxy S3 if you are willing to switch wireless providers. On Amazon Wireless, you can get the the S3 for $79.99 from AT&T if you're a new subscriber. Existing AT&T subscribers, such as yourself, can still get a discount, but it's not as big. Existing AT&T customers can get the Galaxy S3 for $129.99 with a two-year contract if the device is bought through Amazon.

Josh Miller/CNET)

Also on Amazon, Verizon is offering the brown version of the Galaxy S3 for $49.99. It's $149.99 for existing Verizon customers through the Amazon site.

But the best deal by far is from Sprint, which is offering the Galaxy S3 for 1 cent to new subscribers via Amazon. (Keep in mind these deals do not apply if you buy the device directly from the wireless carrier's store or Web site.)

My guess is that prices will continue to drop as the release of the Galaxy S4 approaches. And even after the new phone is on the market, you can bet that carriers are going to look for ways to get rid of their existing Galaxy S3 inventory. Who knows, the carriers may even offer the Galaxy S3 free even to existing customers renewing contracts. Carriers also like offer two-for-one deals too. So there is a chance that the Galaxy S3 could be used in one of those promotions.

The bottom line is that even if you are not sure whether you will buy the Samsung Galaxy S4 or the Galaxy S3, you should still wait. That way you will either get the newest flagship Samsung Android smartphone on the market or you'll get the best deal possible on the slightly older version of the product. Either way, it's a win-win for you.

I hope this answered your question. And good luck!

Help! I don't know if I'm really using Wi-Fi on my smartphone!

Dear Maggie,
I have been reading some of your answers to folks about smartphones and data usage. I don't use a cell phone much except for emergencies, so I bought an AT&T GoPhone plan ($100 per year at 25 cents a minute.) I love technology (a bit like the aunt you mentioned in one of your recent columns) so I recently purchased an AT&T Fusion GoPhone. My minutes roll over so I had about $220 in my account. We have Wi-Fi available in our home, so I thought I could simply utilize that. I did sign-up for a small data plan after I used over $100 of my minutes to download a few things on my phone. Sad to say, I do not understand data vs. Wi-Fi on my phone. I was able to use my old SIM card on my new phone, but you mentioned something about turning off the data on a phone and using your WiFi instead. How does one do that? Seemingly, having downloaded a couple of games and a document or two to my phone, I can use those without incurring any charges. Then I got a charge of over $30 for something I did (I downloaded a ringtone and a
Kindle app), and I am not sure why. Any help you might have would be appreciated.

Thanks,
Sherry

Dear Sherry,
I'm sorry that this is confusing for you. But believe me when I say that you are not alone. I think there are a lot of people out there who get confused about this. Let's see if I can help.

The AT&T Fusion GoPhone is an Android smartphone. It uses an older version of the Google Android OS, known as Android 2.3 Gingerbread.

The first thing you need to make sure Wi-Fi is turned on. Here's how you do that.

• Press Home key
• Press Menu button
• Touch settings
• Touch Wireless networks> Wi-Fi
• Check the Wi-Fi box to turn on Wi-Fi
• Touch a network to connect to that network

If you have secured your home Wi-Fi network, you will be asked to log-in to your network using your username and password. From this time forward, you should always connect to your home Wi-Fi network every time you enter it. You shouldn't have to go into settings and connect to this network. It should do it automatically after the first time.

But since you aren't certain that you are connecting, before you download something, you may want to double check you're connected to Wi-Fi. You can do this by repeating these steps to make sure that you're connected.

There is a chance that your home Wi-Fi network isn't working properly. For example, the wireless router may be operating, but the connection to your wired broadband connection to your house may be having problems. So if you're having trouble connecting to the home Wi-Fi network, I would check your connection to your broadband service.

Another way to check whether you are on Wi-Fi is to look at the Wi-Fi icon in the top right of your screen. If you see the symbol lit up, you are connected to a Wi-Fi network. And all data should be transmitting over Wi-Fi. But if you see a question mark through the Wi-Fi signal, you are not connected and when you download stuff it will go over the carrier data network.

If you really aren't sure about whether you're on Wi-Fi, you can go into the settings of your phone and put the phone into Airplane mode. This will turn off the cellular radio on your phone. You won't be able to receive or make phone calls over the AT&T network when this radio is turned off. But you can leave Wi-Fi on in the airplane setting, which will allow you to connect to your home Wi-Fi network. There should be no question at all if you are in airplane which network you are using since the carrier data network is turned off.

If you do this and are still getting charged for data, then you may want to into an AT&T store and ask the salesperson to help you. There is a chance that you may have some apps running in the background of your phone that are downloading things when you're not in Wi-Fi. Hopefully, a store rep can help you sort this out. Otherwise, it may be a problem with your phone. And the store rep should be able to help you with that or at least credit your account.

I hope this answer was helpful. And good luck!

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.

Inside Organized Retail Crime Raids

We used to call it shoplifting, but these days the foot soldiers of retail crime rings are known as boosters. Police even have an acronym for these operations: ORC, which stands for Organized Retail Crime.

"It's just like a Fortune 500 company," said Sergeant Eric Lee of the Gardena Police Department in Gardena, Calif. "All of this is just organized."

Police say big retail stores, from Walgreens to J.C. Penny, are getting hit by highly sophisticated shoplifting networks that steal and resell everything from underwear to razors to milk. According to the National Retail Federation, theft can amount to annual losses as high as a $37 billion for retail businesses.

"Every store in every city has to go through this," Lee said. "They wait until no one's paying attention and they walk out."

Tide detergent is currently a hot target because it is compact, expensive and easy to sell on the streets for profit, police said. The Street name: "liquid gold."

"Sometimes we get rings that just do alcohol," Lee said. "And then we get some that do just meat and seafood."

Investigators say boosters move the loot for cents on the dollar to fencing operations -- the black market resellers of the stolen goods -- which sell the stolen merchandise in plain sight in stores. Boosters, fencers, Mr. Bigs, all of those involved in these shoplifting operations can potentially make millions a year from boosting and re-selling stolen goods.

Craigslist Crackdown: Cops Go After Thieves Watch Video

And Mike Swett is on the case. A former Riverside County sheriff's deputy in Los Angeles, Swett was badly injured in a car wreck and now works as a full-time private investigator on the ORC beat who has worked with Target, Marshalls, T.J. Maxx. Stores hire him to do his own undercover police work, catching thieves before involving local law enforcement.

"Kind of like working a narcotics case, it's like you've got low-level, mid-level and then top dog," Swett said. "We like to go after the top dog and the only way to get to the top dog is mid-level first."

At his command center -- his apartment -- Swett showed off the boxes upon boxes of tapes and photographs he has collected, the fruits of countless silent stake-out hours.

Swett said he has been casing two joints in L.A. for months, both alleged to be mid-level fencing operations. "Nightline" was invited to ride along with him when he sent undercover agents in for a final reconnaissance mission.

At some stores and shopping malls, clerks do little to stop shoplifters and often let them run, which has contributed to the growing fencing operations.

"[The stores] don't want their employees to get injured," Swett said. "So oftentimes they will call the police, but by the time we get there they are already in their car and they are gone."

This leaves professional investigators like Swett to put the pieces together and bust open the gangs to lead over-stretched police departments to the prey.

When raid day arrived, a motorcade of squad cars departed from the Gardena, Calif., police department and pulled up to one fencing operation. Swett said the merchandise being sold was boosted goods.

"There is Victoria's Secret, expensive Victoria's Secret, the gift sets," he said, pointing down a line of tables. "J.C. Penny, Miramax, its real stuff not counterfeit."

He spotted a bottle of Katy Perry brand perfume, which usually retails for around $90 but one seller had it priced at $59.
