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.

Bangladesh deploys troops as protest toll mounts






DHAKA: Bangladesh deployed troops in the north of the country on Sunday as six more people were killed in fresh clashes over the conviction of Islamist leaders for war crimes in the Muslim-majority nation.

The army was deployed in violence-wracked Shahjahanpur town after more than 5,000 stick-wielding protesters attacked two police stations, forcing police to open fire, they said.

"At least four people were killed in clashes after Jamaat-e-Islami supporters attacked us. The toll could rise," Shahjahanpur district's deputy police chief Moqbul Ahmed told AFP, adding that troops had been deployed to boost security.

Two other people were also killed on Saturday night, including a ruling party student activist who was allegedly hacked to death by suspected Jamaat supporters, police said.

An inter-city train was torched late Saturday in the northwest but there were no casualties, police said.

The death toll in the clashes over the war crimes verdicts has risen to 62 since January 21, including 46 killed in the past four days after Jamaat's vice president was sentenced to death, police said.

Delwar Hossain Sayedee was on Thursday found guilty 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 with outrage from Islamists.

Jamaat says the process is more about settling scores than delivering justice. The party has enforced a nationwide strike on Sunday to protest the verdict and killing of its activists in police "brutalities".

The war crimes trials of a dozen Jamaat and main opposition Bangladesh Nationalist Party (BNP) leaders have opened old wounds and divided the nation, with the opposition parties accusing the government of staging a witch-hunt.

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.

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."

Thai tourist industry 'driving' elephant smuggling






BANGKOK: Smuggling the world's largest land animal across an international border sounds like a mammoth undertaking, but activists say that does not stop traffickers supplying Asian elephants to Thai tourist attractions.

Unlike their heavily-poached African cousins -- whose plight is set to dominate Convention on International Trade in Endangered Species (CITES) talks in Bangkok next week -- Asian elephants do not often make the headlines.

But the species is also under threat, as networks operate a rapacious trade in wild elephants to meet the demands of Thailand's tourist industry.

Camps and zoos featuring elephants tightrope walking, playing football or performing in painting contests employ almost 4,000 domesticated elephants for the amusement of tourists.

Conservation activists accuse the industry of using illicitly-acquired animals to supplement its legal supply, with wild elephants caught in Myanmar and sold across the border into one of around 150 camps.

"Even the so-called rescue charities are trying to buy elephants," said John Roberts of the Golden Triangle Asian Elephant Foundation.

Domestic elephants in Thailand -- where the pachyderm is a national symbol -- have been employed en masse in the tourist trade since they found themselves unemployed in 1989 when logging was banned.

Just 2,000 of the animals remain in the wild.

Prices have exploded with elephants now commanding between 500,000 and two million baht ($17,000 to $67,000) per baby, estimates suggest.

The number of baby elephants "coming into the system" is far higher than would be possible "from actual breeding", said Roberts, whose group decided to stop buying elephants seven years ago and now has 26 residents.

"I cannot see a way to buy an elephant which doesn't cause another elephant to be smuggled," he added.

Between 50 and 100 wild baby or young female elephants are sold from Myanmar each year, according to estimates by British charity Elephant Family.

The group's head of conservation, Dan Bucknell, told AFP that while some trafficked elephants may be taken elsewhere, the majority enter the Thai market.

"Thailand is certainly a hub," he said.

Smuggling such a large mammal should in theory require elaborate planning to avoid the police but in reality traffickers just "do it over a normal road", said wildlife trade researcher Vincent Nijman of Oxford Brookes university.

"Elephants can be in a truck or even walk" across the Thai border in front of complicit customs officers and border guards, he said.

Demand is not only threatening the 4,000 to 5,000 wild elephants in Myanmar, but is also hitting populations in Thailand's other neighbour Laos.

Young domestic elephants are exported across the border, furthering the decline of a population of around 480 animals, said Gilles Maurer of the group ElephantAsia.

Laos, known as the "land of a million elephants", only has between 300 and 500 wild pachyderms left and Maurer said that as the domestic population shrinks, "there is a strong risk" that poachers will turn to them.

Last year Thai authorities conducted several raids on elephant camps and seized some 25 animals -- 19 remain under their protection.

"It is likely the 19 seized elephants were smuggled wild animals as their paperwork did not match up," said forest ranger Pradung Jitraon, of Thailand's National Parks department, who participated in the operation.

Activists have welcomed the initiative but are also calling for broader reforms. "The system now is so weak," said Petch Manopawitr of the World Wildlife Fund in Thailand.

Thailand needs "more control, more transparent monitoring of the population, of what they do in terms of new born elephants", he said, calling for a proper database of elephants, using DNA testing or microchips.

Such a system, he added, would allow foreigners to visit elephant camps safe in the knowledge they are not "harming or threatening the wild population".

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.

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.
