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.

Syrian shells hit Israeli-occupied Golan: army






JERUSALEM: Mortar rounds believed to be have been fired from Syria hit the southern Israeli-occupied Golan Heights on Saturday without causing damage or casualties, the army said.

"Several shells landed and were found in an open area in the southern Golan Heights, most likely due to the fighting in Syria," a spokesman told AFP.

"No injuries or damages were caused. The incident was reported to the United Nations forces, and IDF (Israeli Defence Forces) soldiers continued searching the area," he said.

On Wednesday, a mortar shell struck the central Golan Heights, causing no injuries or damage, after nearly three months of no spillover from the fighting in Syria.

The same day, six Syrians were discharged from an Israeli hospital and returned to Syria, with a seventh staying behind for further treatment.

They were wounded in the fighting over the border and allowed on February 16 to cross into Israel, where they received treatment at Ziv hospital in the northern Galilee town of Safed.

Such incidents have been sporadic but have increased over the past six months as violence from the civil war in Syria seeped across the ceasefire line.

In recent months, there have been several instances of gunfire or mortar shells hitting the Israeli side of the plateau. In November, troops responded with artillery in the first such instance of Israeli fire at the Syrian military since the 1973 war.

Israel seized the Golan from Syria in the 1967 Six-Day War and annexed it in 1981, in a move never recognised by the international community.

It is currently upgrading its security fence along its armistice line with the work expected to be finished by the end of the year.

Why teens are tiring of Facebook




To understand where teens like to spend their virtual time nowadways, just watch them on their smartphones. Their world revolves around Instagram, the application adults mistook for an elevated photography service, and other apps decidely less old-fashioned than Mark Zuckerberg's main kingdom.

And therein lies one of Facebook's biggest challenges: With more than 1 billion users worldwide and an unstated mission to make more money, Facebook has become a social network that's often too complicated, too risky, and, above all, too overrun by parents to give teens the type of digital freedom or release they crave.

For tweens and teens, Instagram -- and, more recently, SnapChat, an app for sending photos and videos that appear and then disappear -- is the opposite of Facebook: simple, seemingly secret, and fun. Around schools, kids treat these apps like pot, enjoyed in low-lit corners, and all for the undeniable pleasure and temporary fulfillment of feeling cool. Facebook, meanwhile, with its Harvard dormroom roots, now finds itself scrambling to keep up with the tastes of the youngest trendsetters -- even as it has a foothold on millions of them since it now owns Instagram.

Asked about the issue, a Facebook spokesperson would only say, "We are gratified that more than 1 billion people, including many young people, are using Facebook, to connect and share."

The data doesn't exist to slap a value on Facebook's teen problem. But we know -- from observing teens, talking to parents and analysts, and from a few company statements -- that age doesn't become Facebook with this group.

In recent weeks, Facebook has told us twice about its teen-appeal problem. When it filed its annual report, it warned investors for the first time that younger users are turning to other services, particularly Instagram, as a substitute for Facebook.

Then, earlier this week, Chief Financial Officer David Ebersman admitted that Instagram, an application he described as popular among the "younger generation," is a "formidable competitor" to Facebook. Which seems odd until you realize that the profit-hungry Facebook isn't yet making a dime from Instagram.

"What we do know is that Instagram is already a very popular service that continues to grow rapidly, and we believe, based on the information that we have, that it's quite popular among these kinds of users that you're asking about, the younger generation. It is very important for Facebook to build products that are useful to those users, and to build products that they feel comfortable ... they can have a good experience with. Definitely high on the list of priorities for us."

The under-13 tween crowd, including one CNET editor's daughter, technically isn't allowed to use the application, as dictated by the terms of service and a federal restriction (although the law is changing this July in ways that will make it easier for kids to join). Yet kids found Instagram anyway, largely because their parents wouldn't let them join Facebook, argues Altimeter Group principal analyst Brian Solis. Teens 13 and up joined Instagram, he said, because Facebook became "too great" a social network where they're now connected to their grandparents.

Isn't it ironic, as Alanis Morissete would say, that Facebook, the one-time underground drug of choice for college kids is now so readily available and acceptable that we all do it in broad daylight, and worse, at work? Sure, a 12-year-old skateboarder can derive some value from Facebook, but in the whitewashed kind of way that the rest of us use LinkedIn.

"We take pictures of food and landscapes," Solis said, "but teenagers use [Instagram] to share pictures of themselves ... the more you share, the greater the reaction, and the more you push outside comfort zones, the more people react."

Tweens and teens are addicted to the idea of eliciting more reactions in the form of likes, followers, and comments, he said. They employ like-for-like photo tactics, use a myriad of hashtags to get their pictures in front of more users, and promote their desire for additional followers in their profiles.

Ascertaining the extent of Instagram's popularity with teens is particularly tricky -- until you talk to them. And some data on the phenomena does exist. Nielsen, one of the few companies to measure teens' online behavior, can only track web usage for this youngest demographic. The analytics firm told me that Instagram was the top photography website among U.S. teens ages 12 to 17 with 1.3 million teens visiting the website during December 2012. By the analytics firm's count, roughly one in 10 online teens in the U.S. visited Instagram in their browser during the month.

Anecdotally, the evidence overwhelmingly points to Instagram as the preferred social network of tweens and teens. A personal relationship provided me with a direct lens to view how two teenage boys used the application in their everyday lives. I also chatted with other kids, some the children of friends, and others I found through friends of friends.


Beth Blecherman's 14-year-old son, who lives in the San Francisco Bay Area, downloaded Instagram when he was 13 because all of his friends were using it as their social network. Marisa, a 16-year-old girl who attends Cathedral City High School in southern California, has been using Instagram for more than a year. She said that a majority of her high school friends are using the application. And a San Diego friend's 12-year-old son is so hooked on the application that he was in tears when his account was temporarily suspended earlier this year.

"Teens recognized Instagram as a social network before anyone else," Solis said. "Everyone else treated it as a camera app."

At the same time, Instagram could disappear from teen consciousness just as easily at it arrived. Remember: Instagram was only 17 months old when Zuckerberg bought it in the weeks prior to Facebook's IPO last May. Parents are starting to understand that their kids haven't developed a fascination with the application to share artistic photos of landscapes and architecture. All of the teens I spoke to have watchful parents who keep an observant eye on their Instagram accounts.


Teens searching for a cyber hangout to call their own Adam McLane, a former youth pastor who hosts educational social media seminars for parents of teens in San Diego, told me that his sessions are dominated by talk of Instagram, with frenzied parents fearful that their innocent young ones are participating in unsavory activities such as bullying or posting inappropriate photos.

The parent factor alone could send kids fleeing to other applications such as Snapchat, Pheed, and Tumblr, all of which appear to have strong teen followings. Investors are betting on Snapchat in particular, which sends more than 60 million short-lived messages daily, because they don't want to miss out on the next Facebook.

"Teens are looking for a place they can call their own," Danah Boyd, a senior researcher that studies how young people use social media for Microsoft, told me. "Rather than all flocking en masse to a different site, they're fragmenting across apps and engaging with their friends using a wide array of different tools. ... A new one pops up each week. What's exciting to me is that I'm seeing teenagers experiment."

This experimental nature puts Facebook in the tricky position of reacting to the whims of transitory teens. Take Facebook's impromptu release of Poke, a mobile phone application, modeled after Snapchat, for sending messages that self-destruct moments later. The company's most reactionary move, however, was its surprise purchase of Instagram, an impulse buy that ultimately cost about $715 million.

Now that Instagram has more than 100 million active users, Facebook's impulsive pickup looks like a smart one. But the dangerous reality is that Facebook is bleeding attention to an application with no advertising model, nor does the social network even understand how Instagram ties in with its own applications.

Facebook doesn't know what teens want. Ebersman said as much, albeit in less direct terms:

"Facebook is a very young company in terms of the age of our employees, and I am hopeful that continues to be an asset for us in terms of having our finger on the pulse of what matters to that particular constituency of users and how we can provide products to satisfy them."

Put that way, Facebook's saving grace might be that its employees are also tiring of Facebook.

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."

Sequester: What Will Happen, What Won't Happen












When it comes to critical elements of the sequester timeline, not much is known -- because federal agencies have been tight lipped.


Asked when specific effects will be felt, officials at three federal departments declined to discuss the timing of sequester cuts and their consequences. Some departments were waiting for President Obama's Friday night sequester order and subsequent guidance they expected to receive from the Office of Management and Budget before talking about what would and wouldn't happen and when.


Read more: 57 Terrible Consequences of the Sequester


"There's no calendar of dates for specific actions or cuts on specific dates," Department of Health and Human Services public affairs officer Bill Hall told ABC News. "Again, these cuts need to be applied equally across all agency programs, activities and projects. There will be wide variation on when impacts will occur depending on a given program."


Some cuts won't be felt for a while because they have to do with government layoffs, which require 30 days notice, in most cases.


For instance, the Federal Aviation Administration won't begin layoffs until at least April 7, one FAA official estimated.


But some cuts don't involve furloughs, and could conceivably be felt immediately.


The Department of Homeland Security declined to comment on the timeline of layoffs to cybersecurity contractors and first responders funded through states, as well as limited Coast Guard operations and cuts to FEMA disaster relief.


The Department of Housing and Urban Development said it could not comment on cuts to housing vouchers, rent assistance for AIDS patients, maintenance for housing projects.

So even as the sequester hits, we still don't know when some of its worst effects will be felt.


Here's what we do know:


What Will Happen Saturday


      Air Force Training. At a briefing Friday, Deputy Defense Secretary Ashton Carter warned that "effective immediately, Air Force flying hours will be cut back."


More from Carter, via ABC News' Luis Martinez: "What does that mean for national security? What it means is that as the year goes on, apart from Afghanistan, apart from nuclear deterrence through two missions we are strictly protecting, the readiness of the other units to respond to other contingencies will gradually decline. That's not safe. And that we're trying to minimize that in every way we possibly can."


      Closed Doors at the Capitol. ABC News' Sunlen Miller reports that Capitol Police issued a memo announcing it would have to close some entrances to the Capitol, writing: "At this time it is anticipated that the U.S. Capitol Police will be required to close some entrance doors and exterior checkpoints, and either suspend or modify the hours of operation for some of the U.S. Capitol Complex posts located inside and outside of the CVC and Office Buildings."


      Capitol Janitor Furloughs. After President Obama warned that janitors at the Capitol will be furloughed, ABC News' Sunlen Miller reported that was not entirely true: The Senate sergeant at arms, Terrance Gainer, told ABC News that no full-time salaried Capitol Police officers would face furloughs or layoffs at this time. They will, however, see a "substantial reduction in overtime," Gainer told ABC News.


      Delayed Deployment for USS Truman Aircraft Carrier. This has already happened, the Associated Press reported Friday morning: "One of the Navy's premiere warships, the aircraft carrier USS Harry S. Truman, sits pier-side in Norfolk, Va., its tour of duty delayed. The carrier and its 5,000-person crew were to leave for the Persian Gulf on Feb. 8, along with the guided-missile cruiser USS Gettysburg."

Smartphone projector breathes life into storybooks



Hal Hodson, technology reporter



Remember your favourite storybook from childhood? Now imagine that the characters that graced its pages didn't only appear in print, but acted out scenes right in front of you, à la magic Harry Potter paintings.


HideOut, a smartphone projector system developed by Karl Willis at Disney Research in Pittsburgh, Pennsylvania, does exactly that by using invisible-ink markers to guide the projected characters of a storybook through an entire other layer of activities.






The projector also lets the user move a digital, animated character over surfaces in the real world. By passing the camera over another of the hidden patterns - which are visible only in infrared - the character can even seem to interact with physical obstacles, as in the video above.


In a paper describing the system, presented this month at the Tangible, Embedded and Embodied Interaction conference in Barcelona, Spain, Willis laid out how projection will move past games and playing to become an important computer-human interaction technology, freeing digital content from the screens.


Willis writes that future smartphones with embedded projectors will be used to browse digital files projected on any wall or table, to augment theme parks with digital characters, or to make digital board games that jump out of the table. "Enabling projected content to be mapped onto everyday surfaces from mobile devices is an important step towards seamless interaction between the digital and physical worlds."

Motor Racing: Button sets pace on second day of testing in Barcelona

 





BARCELONA: Britain's Jenson Button, of McLaren, was quickest on a wet second morning of the final pre-season testing of the winter in Barcelona on Friday.

Button, the 2009 world champion, was 0.216 seconds quicker than Germany's Adrian Sutil, driving for Force India in conditions that started off very wet before beginning to dry up.

Sutil's impressive performance came a day after he was confirmed as the Force India team's second driver for 2013 after a 12-month absence.

His compatriot Niko Huelkenberg, in a Sauber, was third, while world champion Sebastian Vettel was tenth in his Red Bull, for whom Mark Webber had set the quickest pace on Thursday.

Leading times

1. Jenson Button (GBR/McLaren-Mercedes) 1:25.936 (33 laps),
2. Adrian Sutil (GER/Force India-Mercedes) 1:26.152 (42),

U.S. one step closer to Kim Dotcom extradition



The U.S. is one step closer to bringing Kim Dotcom to its shores.


The New Zealand Court of Appeal today ruled that the U.S. government will not be required to turn over all of their evidence against Kim Dotcom in order to obtain his extradition to the States. A summary of its case, the judges ruled, will do just fine.


The Wall Street Journal was first to report on the ruling.



Dotcom had been hoping to force the U.S. government to present all of its evidence against him before it could move forward with hopes to extradite him from New Zealand. For over a year now, the U.S. has been trying to extradite the controversial MegaUpload founder, alleging that he was the brains behind an operation that allows users to store pirated movies, music, and other media illegally.


Dotcom took to his Twitter account today to rail against the court's ruling, saying that "the fight goes on." He added that he will next take his fight to the Supreme Court of New Zealand.


"Am I disappointed about the ruling today?" Dotcom asked. "Yes. Do 'good faith' and 'U.S. government' go together? No. Will I sleek like an innocent baby tonight? Yes."


Today's ruling comes a little over a month after Dotcom announced the launch of Mega, the follow-up to MegaUpload that allows for encrypted cloud storage of files. Like MegaUpload, Mega has caught the ire of copyright owners and the U.S.

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."

Sequester Set to Trigger Billions in Cuts












Nobody likes the sequester.


Even the word is enough to send shivers of fiscal panic, or sheer political malaise, down the spines of seasoned politicians and news reporters. And today, the sequester will almost certainly happen, a year and a half after its inception as an intentionally unpalatable event amid the stalemate of the debt-limit crisis in 2011.


Automatic budget cuts will be triggered across federal agencies, as President Obama will be required to order sequestration into effect before midnight Friday night. The federal bureaucracy will implement its various plans to save the money it's required to save.


Now that the sequester will probably happen, here are some questions and answers about it:


1. HOW BIG IS IT?


The cuts were originally slated for $109 billion this year, but after the fiscal-cliff deal postponed the sequester for two months by finding alternate savings, the sequester will amount to $85 billion over the remainder of the year. Over the rest of the year, nondefense programs will be cut by nine percent, and defense programs will be cut by 13 percent.


If carried out over 10 years (as designed), the sequester will amount to $1.2 trillion in total.


2. WHAT WILL BE CUT, SPARED?


Most government programs will be cut, including both defense and nondefense spending, with the cuts distributed evenly (by dollar amount) over those two categories.






Some vital domestic entitlements, however, will be spared. Social Security checks won't shrink; nor will Veterans Administration programs. Medicare benefits won't get cut, but payments to providers will shrink by two percent. The Children's Health Insurance Program (CHIP), food stamps, Pell grants, and Medicaid will all be shielded from the sequester.


But lots of things will get cut. The Obama administration has warned that a host of calamities will befall vulnerable segments of the population.


3. WHY DOES IT HAVE TO BE SO BAD?


Questions persist over whether or not it really does.


The sequester will mean such awful things because it forces agencies to cut things indiscriminately, instead of simply stripping money from their overall budgets.


But some Republicans, including Oklahoma Sen. Tom Coburn, have suggested that federal agencies have plenty of flexibility to implement these cuts while avoiding the worst of the purported consequences. Louisiana Gov. Bobby Jindal accused President Obama of trying to "distort" the severity of the sequester. The federal government will still spend more money than it did last year, GOP critics of sequester alarmism have pointed out.


The White House tells a different story.


According to the Office of Management and Budget, the sequestration law forces agency heads to cut the same percentage from each program. If that program is for TSA agents checking people in at airports, the sequester law doesn't care, and Homeland Security Secretary Janet Napolitano can't do anything about it.


Agency heads do have some authority to "reprogram" funds, rearranging their money to circumvent the bad effects. But an OMB official told ABC News that "these flexibilities are limited and do not provide significant relief due to the rigid nature of the way in which sequestration is required by law to be implemented."


4. WHEN WILL THE WORST OF IT START?


Not until April -- but some of the cuts could be felt before then.

First mind-reading implant gives rats telepathic power

















Continue reading page

|1

|2








































The world's first brain-to-brain connection has given rats the power to communicate by thought alone.











"Many people thought it could never happen," says Miguel Nicolelis at Duke University in Durham, North Carolina. Although monkeys have been able to control robots with their mind using brain-to-machine interfaces, work by Nicolelis's team has, for the first time, demonstrated a direct interface between two brains – with the rats able to share both motor and sensory information.













The feat was achieved by first training rats to press one of two levers when an LED above that lever was lit. A correct action opened a hatch containing a drink of water. The rats were then split into two groups, designated as "encoders" and "decoders".












An array of microelectrodes – each about one hundredth the width of a human hair – was then implanted in the encoder rats' primary motor cortex, an area of the brain that processes movement. The team used the implant to record the neuronal activity that occurs just before the rat made a decision in the lever task. They found that pressing the left lever produced a different pattern of activity from pressing the right lever, regardless of which was the correct action.












Next, the team recreated these patterns in decoder rats, using an implant in the same brain area that stimulates neurons rather than recording from them. The decoders received a few training sessions to prime them to pick the correct lever in response to the different patterns of stimulation.











Implants linked













The researchers then wired up the implants of an encoder and a decoder rat. The pair were given the same lever-press task again, but this time only the encoder rats saw the LEDs come on. Brain signals from the encoder rat were recorded just before they pressed the lever and transmitted to the decoder rat. The team found that the decoders, despite having no visual cue, pressed the correct lever between 60 and 72 per cent of the time.












The rats' ability to cooperate was reinforced by rewarding both rats if the communication resulted in a correct outcome. Such reinforcement led to the transmission of clearer signals, improving the rats' success rate compared with cases where decoders were given a pre-recorded signal. This was a big surprise, says Nicolelis. "The encoder's brain activity became more precise. This could have happened because the animal enhanced its attention during the performance of the next trial after a decoder error."












If the decoders had not been primed to relate specific activity with the left or right lever prior to the being linked with an encoder, the only consequence would be that it would have taken a bit more time for them to learn the task while interacting with the encoder, says Nicolelis. "We simply primed the decoder so that it would get the gist of the task it had to perform." In unpublished monkey experiments doing a similar task, the team did not need to prime the animals at all.












In a second experiment, rats were trained to explore a hole with their whiskers and indicate if it was narrow or wide by turning to the left or right. Pairs of rats were then connected as before, but this time the implants were placed in their primary somatosensory cortex, an area that processes touch. Decoder rats were able to indicate over 60 per cent of the time the width of a gap that only the encoder rats were exploring.












Finally, encoder rats were held still while their whiskers were stroked with metal bars. The researchers observed patterns of activity in the somatosensory cortex of the decoder rats that matched that of the encoder rats, even though the whiskers of the decoder rats had not been touched.












Pairs of rats were even able to cooperate across continents using cyberspace. Brain signals from an encoder rat at the Edmond and Lily Safra International Institute of Neuroscience of Natal in Brazil were sent to a decoder in Nicolelis's lab in North Carolina via the internet. Though there was a slight transmission delay, the decoder rat still performed with an accuracy similar to those of rats in closer proximity with encoders.











Wake-up call













Christopher James at the University of Warwick, UK, who works on brain-to-machine interfaces for prostheses, says the work is a "wake-up call" for people who haven't caught up with recent advances in brain research.












We have the technology to create implants for long-term use, he says. What is missing, though, is a full understanding of the brain processes involved. In this case, Nicolelis's team is "blasting a relatively large area of the brain with a signal they're not sure is 100 per cent correct," he says.












That's because the exact information being communicated between the rats' brains is not clear. The brain activity of the encoders cannot be transferred precisely to the decoders because that would require matching the patterns neuron for neuron, which is not currently possible. Instead, the two patterns are closely related in terms of their frequency and spatial representation.

US economy grows 0.1% in Q4






WASHINGTON: The US economy grew slightly in the fourth quarter last year, the government said Thursday, revising its prior estimate of a small contraction.

Gross domestic product grew at an annual rate of 0.1 per cent in the October-December period, the Commerce Department said in its second official estimate. In its initial estimate in January, GDP contracted by 0.1 per cent.

The revision did not change the growth rate for all of 2012 of 2.2 per cent, helped by a solid 3.1 per cent pace in the third quarter.

T-Mobile USA adds customers but sheds sales in latest quarter

T-Mobile USA managed to grab more customers last quarter, but that achievement didn't translate into higher sales.


For the fourth quarter, the company added 61,000 customers in total, an improvement of 587,000 over the prior year's quarter. The overall news, however, was good and bad.


The number of prepaid customers grew for the sixth quarter in a row, with 166,000 additions last quarter. But the number of contract customers dropped by 515,000, compared with a loss of 492,000 in the fourth quarter of 2011.


Total revenues for the quarter reached $4.9 billion. Though that marked T-Mobile's second sequential quarter of sales growth, the numbers were down 5.2 percent from 2011's fourth quarter. A 14 percent drop in revenues from contract subscribers was responsible for most of that decline. At the same time, earnings plummeted by 25 percent to a little more than $1 billion.


On the plus side, T-Mobile said that its Value plans are doing well. Introduced last year, the Value plan can potentially save subscribers money by allowing them to pay for the phone in monthly installments. The plan also lets users bring their own unlocked devices to T-Mobile rather than having to shell out for a new one.


Over the fourth quarter, 1.3 million subscribers opted for the Value plan, adding up to more than 6 million Value customers. Around 100,000 iPhone owners have been jumping ship to T-Mobile each month due to the bring-your-own-device option. More than 2 million iPhone users are now on the carrier's network.


In December, T-Mobile USA CEO John Legere confirmed that the carrier would start selling the iPhone sometime this year.


On the horizon, T-Mobile to prepping to merge with MetroPCS in the next couple of months. T-Mobile parent Deutsche Telekom is naturally hoping the deal will pay off in higher revenues and a larger market share.


"We are looking forward to the merger of T-Mobile USA and MetroPCS," Deutsche Telekom CEO Rene Obermann said in a statement. "This combination will substantially benefit the shareholders and customers of both companies by creating the leading wireless value carrier with expanded scale, spectrum and financial resources to compete across the entire U.S. market."

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."

Benedict Pledges 'Obedience' to New Pope












In his farewell remarks to colleagues in the Roman Catholic Church, Pope Benedict XVI, the first pontiff to resign in nearly 600 years, promised "unconditional reverence and obedience" to his eventual successor.


Benedict, in a morning meeting at the Vatican, urged the cardinals to act "like an orchestra" to find "harmony" moving forward.


Benedict, 85, is spending a quiet final day as pope, bidding farewell to his colleagues and moving on to a secluded life of prayer, far from the grueling demands of the papacy and the scandals that have recently plagued the church.


His first order of business was a morning meeting with the cardinals in the Clementine Hall, a room in the Apostolic Palace. Despite the historical nature of Benedict's resignation, not all cardinals attended the event.


With their first working meeting not until Monday, only around 100 cardinals were set to attend, the Vatican press office said Wednesday. Those who are there for Benedict's departure will be greeted by seniority.


Angelo Sodano, the dean of the College of Cardinals, thanked Benedict for his service to the church during the eight years he has spent as pontiff.


Pope Benedict XVI Delivers Farewell Address










In the evening, at 5:00 p.m. local time, Benedict will leave the Vatican palace for the last time to head to Castel Gandolfo, the papal summer residence outside Rome. Before his departure, the German-born theologian will say some goodbyes in the Courtyard of San Damaso, inside the Vatican, first to his Secretary of State Cardinal Tarcisio Bertone and then to the Swiss Guards who have protected him as pontiff.


9 Men Who Could Replace Pope Benedict XVI


From there it is a short drive to a heliport for the 15-minute flight via helicopter to Castel Gandolfo, just south of the city. Benedict will not be alone on his journey, accompanied by members of the Pontifical Household such as two private secretaries, the head of protocol, his personal physician and his butler.


Once Benedict lands in the gardens at Castel Gandolfo, he will be greeted a group of dignitaries, such as the governor of the Vatican City state Giovanni Bertello, two bishops, the director of the pontifical villas, and the mayor and parish priest. Off the helicopter and into a car, Benedict will head to the palace that he will call home for the coming months. From a window of the palace, Benedict will make one final wave to the crowd at the papal retreat.


It is there, at 8:00 p.m., that Benedict's resignation will take effect once and for all. Once the gates to the residence close, the Swiss Guards will leave Benedict's side for the last time, their time protecting the pontiff completed.


Pope Benedict's Last Sunday Prayer Service


For some U.S. Catholics in Rome for the historic occasion, Benedict's departure is bittersweet. Christopher Kerzich, a Chicago resident studying at the Pontifical North American College of Rome, said Wednesday he is sad to see Benedict leave, but excited to see what comes next.


"Many Catholics have come to love this pontiff, this very humble man," Kerzich said. "He is a man who's really fought this and prayed this through and has peace in his heart. I take comfort in that and I think a lot of Catholics should take comfort in that."

US nuclear dump is leaking toxic waste









































Waste from the production of US nukes is on the loose. Toxic cargo is escaping from six of the 177 ageing tanks at the Hanford site in Washington state where the nation stores two-thirds of its high-level nuclear waste, most of it from the production of nuclear bombs.











The site houses 200 million litres of radioactive and hazardous waste, and 67 tanks have leaked waste before. The new leaks undermine recent reassurances that the dump is now secure.













The biggest worry is that highly radioactive sludges containing heat-generating isotopes are corroding the bottoms of the tanks, following work to drain off most of the liquid waste which allowed the isotopes to collect there, says Bob Alvarez of the Institute of Policy Studies in Washington DC.












"There is no immediate public health risk," said Lindsey Geisler, a spokesperson for the Department of Energy. However, much of the waste has already contaminated groundwater, says Tom Carpenter of Hanford Challenge, an environmental watchdog in Seattle, Washington.

Study finds donkey meat in South African burgers






JOHANNESBURG: Unlike Europeans, South Africans do not unwittingly eat horsemeat in their beef burgers and sausages, but they do eat donkey, water buffalo and goat meat, according to a study by the Stellenbosch University.

Over two thirds of meat products tested contained undeclared ingredients, according to a recent research study, prompted by revelations about food production in Europe.

"Our study confirms that the mislabelling of processed meats is commonplace in South Africa and not only violates food labelling regulations, but also poses economic, religious, ethical and health impacts," said animal sciences professor Louw Hoffman.

"Unconventional species such as donkey, goat and water buffalo were also discovered in a number of products," said Hoffman in a statement on the university website.

Up to 68 percent of 139 meat samples from shops and butcheries had irregular ingredients, the DNA-based study found, with pork and chicken most often substituted for other meat.

Researchers even found plant matter in the minced meat, burger patties, sausages and deli and dried meat.

A lack of tough policing had facilitated the practice, said Hoffman.

"Even though we have local regulations that protect consumers from being sold falsely described or inferior foodstuffs, we need these measures to be appropriately enforced."

A vast food scandal has erupted in Europe after horsemeat was found in so-called beef ready-made meals and burgers.

Build and sell an app with no developer skill with AppMachine



Develop apps to sell on the app stores with zero programming skill from 400 Euros.



(Credit:
Andrew Hoyle/ CNET)


BARCELONA, Spain--Developing good apps for iPhone or Android normally takes a lot of skill and potentially tens of thousands of pounds. With new service AppMachine however, you're able to build good looking apps with zero programming knowledge for only 400 euros that you can then submit to the iOS or
Android app stores.


The app development system is mostly browser based. When you first sign up you'll need to choose a name for your app and choose an appropriate theme for the sort of app you're making. It's very similar to the simplistic style of Tumblr blogs, and takes about as much skill.


Adding different types of content is done by choosing one of 20 building blocks including photos, Facebook interaction, maps and contact pages. You can upload locally stored content to the app but the best way to use it is with RSS feeds that can constantly pull in content from your blog, Facebook page, Flickr accounts or various other sources.



If you want to really customise your app, you'll want to opt for the designer option for 699 Euros.

Andrew Hoyle/ CNET)


Once your content is in place, you have various customisation tools at your disposal. You're able to change the overall theme if your original choice doesn't suit, change colour schemes and image layout options. It's free to build your app up until the point of publishing, so if you're not happy with the look, you haven't wasted a penny.


If you want more control, a designer option is available. It lets you customise buttons, and have a greater variety of options for tweaking the layout. The designer option costs 699 euros, but you are able to get a much more personalised app out of it.


When your app is all finished, AppMachine will then take you through the process of submitting your finished product to the app stores. The price doesn't include the 99 Euros you'll need to pay for an iOS developer license, but even with that added cost, the total app price is still a lot cheaper than having apps built by a professional developer.


It's still probably not something the average
iPad user among you will want to shell out for, but it could be an affordable option for small business owners, store owners or professional photographers who want to showcase their wares in app form without shelling out thousands for the privilege. It's opening up to the public in the next few weeks.

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.

Pope Thanks Crowd in Final Address












On his final full day as the leader of the Roman Catholic Church, Pope Benedict XVI thanked a huge crowd for respecting his historic decision to step down and told them that God will continue to guide the church.


"The decision I have made, after much prayer, is the fruit of a serene trust in God's will and a deep love of Christ's Church," Benedict said to cheers in his last public words as pope.


Benedict, 85, is the first pope to resign in 600 years. He told the crowd today that he was "deeply grateful for the understanding, support and prayers of so many of you, not only here in Rome, but also throughout the world."


Pope Benedict's Last Sunday Prayer Service


Under sunny skies on this late February day, hundreds of thousands of people, some waving flags, some banners, flocked to Vatican City to see Benedict make a final lap around St. Peter's Square. Throughout his eight-year papacy, Benedict has conducted a weekly audience from St. Peter's. Before delivering his last papal address today, Benedict waved to the festive group of supporters as he toured the square in his glass-encased popemobile.


The city of Rome planned for more than 200,000 people to head to the Vatican for today's event. Streets around St. Peter's were blocked off to cars as pedestrians from around the world headed to the square.

Papal Appearance: Faithful Flock to Saint Peter's Square Watch Video





9 Men Who Could Replace Pope Benedict XVI


The conclave to elect Benedict's replacement will start next month at a date yet to be determined. Benedict issued a decree known as a "motu poprio" that will allow cardinals to convene the conclave sooner than the March 15 date that would have been mandated under the old rules.


Benedict today asked the faithful to pray for him and for the new pope.


"My heart is filled with thanksgiving to God who ever watches over his church," Benedict said.


The German-born Benedict, who had appeared frail at times in recent months, seemed more energized in his remarks today. He has said he will devote more time to prayer and meditation after he leaves the papacy.


Benedict will meet Thursday with his cardinals in the morning and then flies by helicopter at 5 p.m. to Castel Gandolfo, the papal residence south of Rome. Benedict will greet parishioners there from the palazzo's balcony, his final public act as pope.


Then, at 8 p.m., the exact time at which his retirement becomes official, the Swiss Guards standing outside the doors of the palazzo at Castel Gandolfo will go off duty, their service protecting the head of the Catholic Church finished.


In retirement, Benedict will continue to wear white and will be called "Pope Emeritus," or the "Supreme Roman Pontiff Emeritus" or "Your Holiness," the Vatican announced Tuesday. Benedict will ditch his trademark red shoes, opting for a pair of brown shoes given to him on a trip to Mexico. But he will still reside on Vatican grounds in a former nunnery.


Benedict's final days as pope have been marked by controversy. For nearly a week now Italian newspapers speculated that Benedict really resigned because of a dossier he was given detailing a sex and blackmail scandal in the Catholic Church. The Italian media news reports do not state any attribution.


It turns out a dossier does exist. The Vatican spokesman Monday underscored that the contents of the dossier are known only to the pope and his investigators, three elderly prelates whom the Italian papers have nicknamed "the 007 cardinals."


But the dossier itself will remain "For the Pope's Eyes Only."

China takes steps to clean up 'cancer villages'









































The Chinese government has acknowledged the existence of "cancer villages": areas where rates of cancer are unusually high, probably because of industrial and agricultural contamination of drinking and irrigation water.












The reference to the cancer clusters was in China's first ever five-year plan for environmental management of chemicals, released on 20 February. The Chinese media, translating parts of the report, said it links water pollution to "serious cases of health and social problems like the emergence of cancer villages in individual regions".












The term has caught on over the past few years as the media in China and elsewhere reported on apparent cancer hotspots. It gained prominence in 2009 when a journalist plotted 40 of them on a Google Map. Some reports have suggested there might be more than 450 such clusters.












According to recent data, deaths from cancer in China increased by 80 per cent between 1970 and 2004. The disease now accounts for 25 per cent of deaths in cities and 21 per cent in rural areas. However, people in China have an 18.9 per cent risk of getting cancer before the age of 75, compared with 29.9 per cent for people in the US and 26.3 per cent in the UK.












One "typical cancer village", as it was called by researchers from Dezhou University in Shandong province who studied it in 2008, had between 80 and 100 deaths from cancer over five years in a population of only 1200.












But proving a link between pollution and cancer requires more detailed evidence, says Tim Driscoll, an epidemiologist at the University of Sydney and science adviser to Cancer Council Australia. However, Driscoll also says it doesn't really matter – if there is dangerous pollution anywhere, it should be cleaned up.












And that is the plan. China's Ministry for Environmental Protection has drawn up a list of 58 chemicals that will be tracked with a registry, including known and suspected carcinogens and endocrine disrupters. Before the end of the 2015, they will subdivide the list into chemicals to be eliminated and those to be reduced.











Big shift













Creating a plan to eliminate some chemicals is a big shift, says Yixiu Wu, a Greenpeace East Asia campaigner based in Beijing, who says even committing to controlling these chemicals would have been a step forward.












The ministry's acknowledgement of the problem is "really important and it is another reflection of the government's shift towards more transparency in pollution information," says Sabrina Orlins from the Institute of Public and Environmental Affairs, a non-profit body in Beijing.












"Increased environmental information leads to increased public awareness where people can have the chance to exert pressure on big water polluters to adopt clean-up measures and be more accountable," she says.












That accountability is where the five-year plan is lacking, says Wu. "It is still a question whether the government is willing to release all the information about the factory locations and their environmental risk," she says. "It is very important for people who are living nearby."












Wu says the motivation to develop the plan comes from an increasing awareness of the human cost of pollution as well as the country signing up to several international conventions designed to curb pollution.

Mobile makers set sights on grandparents






BARCELONA: As smartphone giants Apple and Samsung battle for the wallets of tech-savvy youngsters, a growing number of manufacturers is trying to lure a fast-growing new market: their grandparents.

Handset makers at the world's biggest mobile fair in Barcelona, Spain, showed off a slew of new devices aimed at the hundreds of millions of older people put off by the complexity of the latest iPhones and Android-powered smartphones.

One of the leaders of the segment in Europe, Austrian firm Emporia, launched a new handset, the Emporia Connect, at the February 24-28 Mobile World Congress.

The sleek-looking black and silver flip phone is designed not to be "stigmatising" yet easy enough for older buyers to use, said Emporia's general manager for France, Christophe Yerolymos.

It has a keypad with larger numbers and an emergency button that will send an SOS along with data pinpointing the location of the phone.

The phone features a system called Emporia Me, with an array of remote control features for the owner's family, allowing a child or grandchild to check the device's location, battery status, or ensure the volume is up.

While it is not a smartphone and has no mapping service, it does have an orientation feature that lets a user push a single button to get turn-by-turn audible instructions for returning to a car while on a shopping trip, for example.

"Emporia is a company in growth, strong growth, even in the heart of the economic crisis we're in at the moment in Europe," said Yerolymos.

Japan's Fujitsu rolled out a European version of a smart phone for seniors, the Stylistic S01, which first launched in mid-2012 in Japan where it lured buyers from a wider age range than the group anticipated, from 45 years upwards.

It is an Android-based smartphone with large, simplified icons, and a "family alert" button that will send a message along with geo-localisation data.

But it also has an unusual touch-screen that will only respond when the user presses a bit harder so as to avoid launching applications by mistake, said Fujitsu Europe-Middle East-Africa product marketing director James Maynard.

"You can actually pre-touch and then when you know which button you want to press, you can exert a little bit more pressure," he said.

"It's made to grow with you so as you become more confident you naturally will exert more pressure on to the device. It's a stepping stone from a feature phone to a smartphone and using a touch panel for the first time."

Kapsys, a French firm, showed off its SmartConnect handset aimed at seniors.

The firm is in discussions with operators including Orange and is hoping to launch the device for about 400 euros (US$520) in Europe in June and then in the United States by the end of 2013, said chief executive Aram Hekimian.

The SmartConnect boasts familiar features for the market: large icons, text in large characters, remote access for family members and also an SOS button with geo-localisation.

But it also incorporates a digital magnifier, enabling the user to roll the phone over text to facilitate reading, for example. The phone is rich in voice command functions, too, allowing the user to avoid fiddly buttons.

"Seniors today are used to having access to technology. As they get older they will want access to the same functions, the same technologies," Hekimian said.

Kapsys estimated the potential market for the telephone at 600 million people, he said. "Our goal is to capture one percent of that market by 2015."

Looking for a big tablet? The iPad famously (or infamously) starts at $499. The
Google Nexus 10: $399. Even the comparatively affordable Kindle Fire 8.9 will set you back $299.


For a limited time, and while supplies last, Acer (via Ebay) is selling the refurbished Iconia Tab A210 10.1-inch Android tablet for $199.99 shipped. Deal? More like steal.


The Iconia A210 features a 1.2GHz Tegra 3 processor, 16GB of storage (expandable via microSD cards), the aforementioned 10.1-inch screen (running at a competitive, if not spectacular, 1,280 x 800), and
Android 4.0. Acer will push out an Android 4.1 (Jelly Bean) update in the (presumably) not-too-distant future.


The
tablet weighs 1.5 pounds, so it's a bit on the heavy side, and it has only a front-facing camera. It also lacks an HDMI output, an issue only if you like to wire your tablet to a TV.


CNET hasn't reviewed this model, but over at Amazon (where it sells for $349.99), two dozen buyers collectively rated it 4.5 stars out of 5. Most of the reviews are positively gushing.


Because it's a refurb, you get only a 90-day warranty. If you can live with that, you stand to save a full $150 on this big beauty. Who's in?


While you're mulling that over, take my new poll: How do you use your tablet?

Sharks Warn Off Predators By Wielding Light Sabers


Diminutive deep-sea sharks illuminate spines on their backs like light sabers to warn potential predators that they could get a sharp mouthful, a new study suggests.

Paradoxically, the sharks seem to produce light both to hide and to be conspicuous—a first in the world of glowing sharks. (See photos of other sea creatures that glow.)

"Three years ago we showed that velvet belly lanternsharks [(Etmopterus spinax)] are using counter-illumination," said lead study author Julien Claes, a biologist from Belgium's Catholic University of Louvain, by email.

In counter-illumination, the lanternsharks, like many deep-sea animals, light up their undersides in order to disguise their silhouette when seen from below. Brighter bellies blend in with the light filtering down from the surface. (Related: "Glowing Pygmy Shark Lights Up to Fade Away.")

Fishing the 2-foot-long (60-centimeter-long) lanternsharks up from Norwegian fjords and placing them in darkened aquarium tanks, the researchers noticed that not only do the sharks' bellies glow, but they also had glowing regions on their backs.

The sharks have two rows of light-emitting cells, called photophores, on either side of a fearsome spine on the front edges of their two dorsal fins.

Study co-author Jérôme Mallefet explained how handling the sharks and encountering their aggressive behavior hinted at the role these radiant spines play.

"Sometimes they flip around and try to hit you with their spines," said Mallefet, also from Belgium's Catholic University of Louvain. "So we thought maybe they are showing their weapon in the dark depths."

To investigate this idea, the authors analyzed the structure of the lanternshark spines and found that they were more translucent than other shark spines.

This allowed the spines to transmit around 10 percent of the light from the glowing photophores, the study said.

For Predators' Eyes Only

Based on the eyesight of various deep-sea animals, the researchers estimated that the sharks' glowing spines were visible from several meters away to predators that include harbor seals (Phoca vitulina), harbor porpoises (Phocoena phocoena), and blackmouth catsharks (Galeus melastomus).

"The spine-associated bioluminescence has all the characteristics to play the right role as a warning sign," said Mallefet.

"It's a magnificent way to say 'hello, here I am, but beware I have spines,'" he added.

But these luminous warning signals wouldn't impede the sharks' pursuit of their favorite prey, Mueller's bristle-mouth fish (Maurolicus muelleri), the study suggested. These fish have poorer vision than the sharks' predators and may only spot the sharks' dorsal illuminations at much closer range.

For now, it remains a mystery how the sharks create and control the lights on their backs. The glowing dorsal fins could respond to the same hormones that control the belly lights, suggested Mallefet, but other factors may also be involved.

"MacGyver" of Bioluminescence

Several other species use bioluminescence as a warning signal, including marine snails (Hinea brasiliana), glowworms (Lampyris noctiluca) and millipedes (Motyxia spp.).

Edith Widder, a marinebiologist from the Ocean Research and Conservation Association who was not involved in the current study, previously discovered a jellyfish whose bioluminescence rubs off on attackers that get too close.

"It's like paint packages in money bags at banks," she explained.

"Any animal that was foolish enough to go after it," she added "gets smeared all over with glowing particles that make it easy prey for its predators."

Widder also points out that glowing deep-sea animals often put their abilities to diverse uses. (Watch: "Why Deep-Sea Creatures Glow.")

"There are many examples of animals using bioluminescence for a whole range of different functions," she said.

Mallefet agrees, joking that these sharks are the "MacGyver of bioluminescence."

"Just give light to this shark species and it will use it in any possible way."

And while Widder doesn't discount the warning signal theory, "another possibility would be that it could be to attract a mate."

Lead author Julien Claes added by email, "I also discovered during my PhD thesis that velvet belly lanternsharks have glowing organs on their sexual parts."

And that, he admits, "makes it very easy, even for a human, to distinguish male and female of this species in the dark!"

The glowing shark study appeared online in the February 21 edition of Scientific Reports.

First Lady Sees 'Movement' in Childhood Obesity












As she celebrates the third anniversary of her Let's Move! initiative, first lady Michelle Obama told "Good Morning America" co-anchor Robin Roberts that the country is seeing real "movement" on the issue of childhood obesity.


"We've really changed the conversation in this country. When we started, there were a lot of people in this country who would have never thought that childhood obesity was a health crisis. But now we're starting to see some movement on this issue," the first lady told Roberts. "Our kids are eating better at school. They're moving more. And we're starting…to see a change in the trends. We're starting to see rates of obesity coming down like never before."


"What we're seeing is that there's hope, and when a nation comes together, and everyone is thinking about this issue and trying to figure out what role they can play, then we can see changes," she said.


Mrs. Obama is set to embark on a star studded national tour this week to promote and celebrate her Let's Move! initiative. Her first stop will be in Clinton, Miss. on Wednesday when she appears at an event highlighting healthy school lunches with Rachael Ray.


"I'm going back to Mississippi because when I first went there, Mississippi was considered one of the most unhealthy states in the nation," Mrs. Obama said.

"If we could fry water in Mississippi, we would, we would do that," Roberts, who grew up in Pass Christian, Mississippi, said. "Food is a culture."


"But the good news in Mississippi is that they've seen a decline in childhood obesity of 13 percent, so we're gonna go celebrate and highlight what has been going on there. There's still work to do," the first lady said.


On Thursday, the first lady will travel to her hometown of Chicago, where she will be joined by Olympic gymnasts and tennis star Serena Williams to promote more physical activity in schools. Later in the day, Mrs. Obama will discuss healthy food choices at a Wal-Mart store in Springfield, Mo.


Mrs. Obama said she will announce a new initiative called the "My Plate Recipe Partnership," which will provide families with online access to healthy recipes that meet the My Plate guidelines, the U.S. Department of Agriculture's replacement of the food pyramid.


"More and more chefs, more and more food companies are understanding that they have to find ways to help families do this in a way that's gonna taste good, that kids are gonna like it," she said.


The first lady, Roberts and Chef Marcus Robert Samuelsson, who owns Red Rooster Harlem in New York City, cooked a healthy meal of beef stir fry and broccolini together on the "Good Morning America" set. Mrs. Obama admitted "it's been a while" since she's cooked for her family, but said she looks forward to the day she can whip up meals for her husband and daughters.


"I walk in the kitchen every day, every day," she joked.


But cooking for her family isn't the only thing Mrs. Obama said she misses since becoming first lady.


"Going to Target for me is like a dream, you know? That one time I went, you noticed it created a stir. I'm gonna do it again, doggone it. Next four years, I'm going out. I'm breaking out. I'm gonna disguise Bo. I'm gonna put on a coat. I'm gonna take a walk, and my agents won't know a thing. Don't tell 'em," she joked.
