US Seeks to Confirm Report of Terror Leader's Death

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

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

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

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

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

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

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

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

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

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

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

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

ABC News' Clayton Sandell contributed to this report.

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.

Chilling documentary accuses Sri Lanka of war crimes

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Black Hole Spins at Nearly the Speed of Light

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

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

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

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

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

Galactic Monster

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

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

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

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

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

Tracking the Universe's Evolution

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

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

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

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

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

Obama Signs Order to Begin Sequester Cuts

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

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

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

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

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

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

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

Sequestration Deadline: Obama Meets With Leaders Watch Video

Sequester Countdown: The Reality of Budget Cuts Watch Video

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

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

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

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

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

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

Boehner: No New Taxes to Avert Sequester

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

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

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

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

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

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

Mystery ring of radiation briefly encircled Earth

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

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

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

Mystery acceleration

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

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

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

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

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

Spacecraft malfunctions

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

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

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

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

Needy families on public assistance scheme to get higher payouts

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

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

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

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

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

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

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

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

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

Do Not Track privacy bill reintroduced in Senate

Senator Jay Rockefeller

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

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

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

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

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

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

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

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

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

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

Scarred Duckbill Dinosaur Escaped T. Rex Attack

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

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

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

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

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

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

A Terrible Attacker

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

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

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

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

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

Dog-Eat-Dog

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

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

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

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

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

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

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

Mysterious Escape

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

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

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

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

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