Get cirrus in the fight against climate change



































FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.












In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.












Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.












The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).


















But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.












Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."












Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

10 police killed in Afghanistan suicide attack: official






KABUL: At least 10 policemen were killed and 18 others, mostly civilians, were wounded in a suicide attack Saturday in a crowded area of the northeast Afghan city of Kunduz, provincial authorities said.

The attacker, who was on foot, detonated his explosives next to a group of police officers, according to several sources.

"We have 10 dead, including the counter terrorism police chief and head of traffic police and their bodyguards," Sayed Sarwar Hussani, Kunduz police spokesman told AFP.

Thirteen civilians and five policemen were wounded in the blast, Hussani said, adding that the final death toll may rise.

The attack was "the work of the enemies of Afghanistan", he said, using a phrase common among Afghan officials to describe Taliban insurgents.

AFP could not immediately reach the Taliban for comment on the attack, which has so far not been claimed by any group.

Afghanistan's interior ministry and the provincial governor spokesman Enayatullah Khaleeq confirmed the toll.

According to the head of the Kunduz health department, Saad Mukhtar, 19 people in total were wounded in the attack, which police officials said took place around 5:20 pm, 12:50 GMT.

Such attacks have in the past been blamed on Taliban insurgents who are leading an 11-year insurgency against the US-backed government of President Hamid Karzai.

Taliban militants have stepped up their fight against Afghan troops as the country's forces are increasingly taking over security responsibility from US-led NATO troops.

Earlier Saturday, a suicide attacker on a bicycle killed two civilians in southeastern Afghanistan's Ghazni province, and on Friday a suicide bomber in a car attacked a NATO convoy in Afghanistan's strategic Kapisa province, killing at least five civilians and wounding 15 others.

Also this week a squad of Taliban suicide bombers attacked Kabul traffic police headquarters in the heart of the city, killing three police officers and wounding dozens others.

The attacks come at a crucial juncture for Afghanistan as US-led NATO troops are preparing for their withdrawal from the country by the end of 2014. Afghan and international observers have predicted a civil war could grip the country once foreign troops have pulled out.

Oppo BDP-105: Not your average Blu-ray player



The Oppo BDP-105 Blu-ray, SACD, and DVD-Audio player

Oppo)


Even by Oppo's high standards the BDP-105 is an extraordinary Blu-ray player. Sure, it's loaded with up-to-the-second features -- 4K upscaling, 2D-to-3D conversion, and a high-quality USB 2.0 digital-to-analog converter -- but what really makes the Oppo special is the sound. Pop the cover and look inside and you'll see why. Most of the 17-pound component's chassis space is devoted to the audio circuitry. That's nice, but the audio advantages will be completely irrelevant if you connect the BDP-105 to your receiver with a HDMI cable (the digital-to-analog conversion would then be handled in the receiver). The 105 was designed for buyers still using older $1,000 or $2,000 receivers from the days before HDMI connectivity, that would like to hear the Blu-rays' high-resolution DTS Master Audio or Dolby TrueHD soundtracks at their best. Since the audio won't be transmitted over the HDMI cable, you would run audio cables between the 105's seven- or five-channel analog outputs and the AV receiver's analog inputs.

Or you could forgo the receiver entirely and hook up the BDP-105 directly to a five- or seven-channel power amplifier. That approach would produce better sound quality, but would lack the connectivity, flexibility, and convenience of today's better receivers. Still, the BDP-105/power amp combo would sound better and be more powerful than most top-of-the-line receivers. The 105's connectivity options won't match any decent receiver, but its connectivity suite is a lot more extensive than most Blu-ray players. The Oppo has two HDMI inputs, so you can connect external devices such as set-top boxes and network streaming devices, three USB 2.0 ports, coaxial and optical digital inputs for satellite boxes, televisions, video-game consoles, etc., and there's a built-in headphone amplifier. The BDP-105's extensive bass management options are on par with a lot of AV receivers. The player's digital volume control is easy to use.


For my listening tests, I hooked up the BDP-105 ($1,199) with an assortment of self-powered Audioengine and Emotiva monitor speakers, and a Hsu subwoofer. With this setup I didn't need to use an AV receiver or separate power amp, but the Raconteurs' "Live at Montreux" Blu-ray was vivid and very live sounding. The system's freewheeling dynamics were really impressive, and the surround mix on King Crimson's "Red" DVD-A projected a remarkably seamless wrap-around soundstage. Each instrument was precisely focused in a near 360-degree sound environment.



The BDP-105 has full speaker setup and bass management options, just like an AV receiver.

Steve Guttenberg/CNET)


Classical music on SACD was just as impressive, the front three speakers produced a three-dimensional soundstage with lots of depth, and string tone was top notch. Dramatic movies on Blu-ray and DVD sounded great. I plugged headphones into the BDP-105, but the sound wasn't special, Schiit Audio's $99 Magni headphone amp was a lot better.


The $499 Oppo BDP-103 shares most of the BDP-105's features, but lacks the upgraded digital-to-analog converters, so if you're planning on using HDMI to connect the player to your receiver, buy the 103, and save $700. You can use the 103's 7.1 analog outputs with an old high-end receiver lacking HDMI connectivity, but the 103's digital converters are a step down from the ones in the 105.


The BDP-105 is an update of the Oppo BDP-95, and the new one has lots of features the old player lacks, but the two players sound about the same. Oppo still has 95s in stock and sells them for $799.


Oppo sells direct and offers a 30-day money-back guarantee, and the return shipping is free.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

Photograph by Art Wolfe, Getty Images

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Cops Using More Private Cameras to Nab Suspects













Philadelphia detectives were able to quickly make an arrest in the murder and burning of a female pediatrician by viewing surveillance video of nearby stores and a hospital that captured the suspect entering the doctor's home and later getting into his truck.


In the hours after Dr. Melissa Ketunuti's body was found strangled and burning in her basement, city's Homicide Task Force collected surveillance footage from a coffee shop, drug store and hospital overlooking Ketunuti's block. It was footage taken from Ori Feibush's coffee shop that allowed cops to identify Smith.


The suspect, an exterminator named Jason Smith, soon confessed to detectives, police said.


Lately a range of crimes have been solved by the seemingly ubiquitous security videos maintained by private companies or citizens, and investigators have been able to quickly apprehend suspects by obtaining the video, deftly turning private cameras into effective police resources.








Philadelphia Police Arrest Suspect in Doctor's Killing Watch Video









Pa. Doctor Killing: Person of Interest in Custody Watch Video







Private surveillance cameras have become so pervasive that the face of a suspect who allegedly shot a Bronx, N.Y., cab driver in a botched robbery on Jan. 14 was splashed throughout the media within days because the cabbie had rigged his vehicle with a camera.


The New York Police Department arrested Salvatore Perrone after he was caught on surveillance video recorded near two of three shopkeeper slayings in Brooklyn, N.Y., in November. He has since been charged with murder.


And in Mesa, Ariz., surveillance footage taken in November by resident Mitch Drum showed a man rolling on the ground trying to extinguish flames that had engulfed his shirt, which had caught fire while he was allegedly siphoning gas from a car by Drum's house. The man was arrested.


Though surveillance cameras have been a staple of security since a network of government operated cameras dubbed the "ring of steel" was introduced in London in the early 1990s, police have recently launched programs to partner with more businesses.


In Philadelphia, police have launched a program for businesses to register private cameras with the department. According to the SafeCam website, businesses will only be contacted when there is a criminal incident in the vicinity of the security camera. At that point, police will request a copy of the footage for their investigation.


"Businesses are saying, 'I have a camera at this location, and it may or may not be of use to you. It's a registration to say, 'feel free to call me,'" Sgt. Joseph Green told ABCNews.com

Hagfish gulped up in first video of deep-sea seal hunt



Sandrine Ceurstemont, editor, New Scientist TV






We no longer have to imagine elephant seals feasting in the deep sea. An underwater camera has filmed one slurping up a hagfish, the first sighting of seal predation on the sea floor.







The event was captured by a Neptune Canada live video stream in the north-east Pacific Ocean and spotted by a teenager who was watching the feed. Marine mammal experts later identified the moustached face in the corner of the frame as an elephant seal, one of the few seal species that spends most of its time underwater. In this case, it was observed at a depth of 894 metres, but the animals can descend more than 1500 metres below the surface, holding their breath for longer than 100 minutes.



The sighting shows the value of citizen science: Steven Mihály from Ocean Networks Canada, based in Victoria, British Columbia, says that although data-mining techniques could be used to sift through the reams of underwater video, human observers are still most effective at picking out events of interest.

US scholar urges dramatic rethink on Taiwan






WASHINGTON: With Beijing growing in strength, a US scholar is calling for a major rethink on Taiwan in which the island would cut its troop numbers in half and rebrand its army as a self-defence force.

The proposal marks a rare break from the conventional view of American and Taiwanese policymakers that the island needs to close the military gap with Beijing, but its author said an opposite course could strengthen Taipei.

Scott Bates, president of the Washington-based Center for National Policy, said the balance was "irretrievably shifting" in China's favor and it was politically and economically unrealistic that Taiwan would commit enough to close the gap.

Instead, Taipei can take the lead by halving the size of its army, rebranding it as a Self-Defence Force in the style of Japan and renouncing any military action on mainland China's soil, he argued.

"If Taiwan were to take a bold step like this, that would change perceptions on the mainland and perhaps win some popular support for the Taiwanese position," said Bates, a former congressional aide.

"If there were a showdown, it might make (Beijing) think twice."

Taiwan should turn the new force into a disaster response team ready to deploy throughout Asia and also highlight the island's democracy through a major initiative that supports civil society across the continent, Bates said.

And instead of waging a battle to preserve a dwindling number of nations' recognition of Taipei instead of Beijing, Taiwan can use its diplomatic resources to seek solutions on Asia's bitter territorial disputes, he said.

The new Taiwanese approach would give the island the moral high ground, winning over global opinion and ensuring that China would appear to be the aggressor if it attacked, he argued.

"Mainland Chinese public opinion is beginning to matter more. The Chinese Communist Party cannot ignore its own people without repercussions," Bates said.

China considers Taiwan to be a territory awaiting reunification, by force if necessary. China's defeated nationalists fled to Taiwan after defeat by the communists in 1949, with the island developing into a self-ruling democracy.

The United States switched recognition from Taipei to Beijing in 1979 but at the same time Congress passed the Taiwan Relations Act, which requires Washington to provide the island with means to defend itself.

Bates said that his proposal would complement efforts by Taiwan President Ma Ying-jeou, who has sought to ease tensions with China by expanding economic ties, though domestic critics accuse Ma of jeopardising the island's de facto independence.

Bates supported the continuation of the Taiwan Relations Act, saying the island needed a credible deterrent. While cutting its army, Bates called for Taiwan to launch a major upgrade of its air defences and navy to show that any effort to gain supremacy over the island would be costly.

The Taiwan Relations Act enjoys virtually unanimous support in the US Congress, where lawmakers have pressed President Barack Obama to sell to the island new F-16 jets - a step that China strongly opposes.

Bates' ideas, however, are unlikely to win quick support.

Joseph Bosco, a former Pentagon official, sharply criticised the proposal, saying it went against accepted concepts of deterrence and that Taiwan already had the moral high ground.

"Taiwan does not need to disarm unilaterally in order to prove its moral or political legitimacy," Bosco said on Wednesday at an event where Bates presented his proposal.

Bates, who spoke last year at Taiwan's National Defence University and wrote an opinion piece in the Taipei Times, said he wanted to start a debate.

"It doesn't have to be my plan, but there does have to be a strategic rethink," he said.

Samsung unveils rugged Galaxy phone for the outdoor type



Galaxy Xcover 2

Samsung)


Samsung has created a new smartphone that can handle the great outdoors and even spend time underwater.


Announced today, the Galaxy Xcover 2 is built as a durable and rugged device, according to Samsung. The phone is both dustproof and sandproof.


It can also hold its breath underwater, at least at a depth of around three feet for up to 30 minutes. You probably won't be making too many phone calls under the water, but the Xcover 2's camera can come in handy if you want to snap photos of life under the sea.


The phone provides Google map information and an enhanced GPS/GLONASS feature. Combing both the U.S.-based GPS and Russia's GLONASS can track your location more accurately, according to Samsung.


The camera's LED flash is bright enough so it can be used like a torch in dark conditions. The 1,700mAh battery boasts a capacity of 570 hours. To get in shape, the phone includes a Cardio Trainer Pro app so you can set up and monitor a personalizing training program.



Outfitted with
Android 4.1 Jelly Bean, the Xcover 2 is powered by a 1GHz dual-core processor. The 4-inch screen offers a WVGA display.


A 5-megapixel autofocus camera is found in the back, while a VGA camera faces front. The phone is equipped with Bluetooth version 4.0, which Samsung says can detect other Bluetooth devices up to 164 feet away.


Samsung has not yet announced where or when the phone will be available, nor how much it will cost. But the timing is right for the company to show off the Xcover 2 and reveal more details at next month's Mobile World Congress in Barcelona.

8 Other Nations that Send Women to Combat


As the Pentagon works to figure out precisely how it will integrate women into military specialties previously closed to them—including infantry and artillery units—top U.S. defense officials are actively studying other militaries around the globe that have already sent women to combat.

The review includes researching the experiences of Australia, Canada, and other nations with whom American troops have worked closely in Iraq and Afghanistan, according to a senior Pentagon official. Some countries have had "three to ten years to go through this process, to integrate women" into combat roles, the official said.

There are roughly a dozen nations that have opened "close combat roles" to women. Those roles are defined by a 2010 British Ministry of Defense (MOD) study as those that include "engaging an enemy on the ground ... while being exposed to hostile fire and a high probability of physical contact with the hostile forces personnel."

In many parts of the world, these efforts have moved quickly once they've begun. Though women in Poland were not even accepted at the nation's military academies until 1999, for example, the country passed a law in 2004 requiring women with college nursing or veterinary degrees to register for compulsory service.

Of the dozen or so countries that allow women to be part of combat units, here are those with the fewest restrictions on what women can do:

Australia: Aside from the U.S., this is the country to most recently remove barriers to its front-line units, provided women meet the physical requirements. In 2011, Australia's defense minister announced that the last 7 percent of positions that had been closed to women—including Special Forces, infantry, and artillery—would be opened up to them.

Driven in large part by a string of sex scandals, the move includes a 5-year transition plan. At its height, Australia had more troops in Afghanistan than any non-NATO country, and women currently account for roughly 10 percent of all Australia's deployed troops.

Canada: In 1989 Canada opened all combat roles except those involving submarine warfare to women. In  2000, women were given the green light to serve on subs as well. Three years later, the first female was assigned to serve as captain of a Canadian warship, while another woman became the first female deputy commanding officer of a combat arms unit.

Roughly 15 percent of Canadian military forces are now women, while 2 percent of combat troops (99 troops) are female. In 2006, Canada lost its first female soldier—a forward artillery scout—in combat with Taliban forces.

Denmark: Since 1988, Denmark has had a policy of "total inclusion," which came on the heels of 1985 "combat trials" exploring the capabilities of women to fight on the front lines. "Danish research showed that women performed just as well as men in land combat roles," according to the British MOD study. Although all posts are open to women, physical requirements have so far prevented them from joining the country's Special Operations Forces.

France: Women make up nearly one-fifth of the French military and can serve in all posts except on submarines and in the riot-control gendarmerie. Though permitted to serve in the combat infantry, however, most chose not to. As a result, women make up only 1.7 percent of that force.

Germany: In 2001, the country opened German combat units to women, dramatically increasing the recruitment of female soldiers into the ranks. The number of women in the German Armed Forces is now three times as high as in 2001. As of 2009, roughly 800 female soldiers were serving in combat units.

Israel: In 1985 the Israeli Defense Force (IDF) began putting women into combat positions and by 2009 women were serving in artillery units, rescue forces, and in anti-aircraft forces. While women must take part in compulsory military service, they are conscripted for only two years, versus three for men.

A study on the integration of female combatants in the IDF between 2002 and 2005 found that women often exhibit "superior skills" in discipline, motivation, and shooting abilities, yet still face prejudicial treatment stemming from "a perceived threat to the historical male combat identity."

New Zealand: Women have been able to serve in all defense units, including infantry, armor, and artillery units, since the country passed a law to that effect in 2001. A report four years later found that the move helped drive a societal shift that "values women as well as men," but that the integration of women into the combat trades "needed a deliberate and concerted effort." The British MOD report concluded that there has been "variable success in attracting and recruiting women to these areas."

Norway: In 1985, Norway became the first country in NATO to allow women to serve in all combat capacities, including submarines. Norwegian women are also subject to the draft in the event of a national mobilization. "The few women that are attracted by the infantry and cavalry do a great job in the Norwegian Army," says Col. Ingrid Gjerde, an infantry officer in the Norwegian military for 25 years.

"I have to be clear: You have to meet the physical standards, because the job is still the same. It works very well as long as women hold the standards," added Colonel Gjerde, who was the commander of Norwegian forces in Afghanistan in 2012. "It's not a big deal because women who go into these fields know the standards, and it's not that hard for women to train up to the standards if they really want."

Mars Rover Celebrates Milestone on Red Planet













It was never supposed to last this long. When the Mars rover Opportunity settled on the Martian surface nine years ago today, mission managers at NASA said they would be pleased if it lasted for 90 days.


Instead, it's been 3,201 days, and still counting. The rover has driven 22.03 miles, mostly at a snail's pace, from one crater to another, stopping for months at a time in the frigid Martian winters. The six motorized wheels, rated to turn 2.5 million times, have lasted 70 million, and are all still working.


"Opportunity is still in very good health, especially considering what it's gone through," said John Callas, manager of NASA's Mars Exploration Rover project. The surface of Mars is a pretty tough place; there can be temperature fluctuations of a hundred degrees each day. That's pretty hard on the hardware."


Video: '7 Minutes of Terror: A Landing on Mars


When Opportunity and its twin rover, Spirit, reached Mars in January 2004, there was a fair bit of sniping that NASA, with all that 90-day talk, was playing down expectations. It escalated when Steve Squyres of Cornell University, the principal investigator for the missions, said things like, "We're on Sol 300 of a 90-Sol mission." (A Sol is a day on Mars, and lasts 24 hours, 39 minutes.) Callas and others have insisted that the prediction was based on engineering, not a nod to public relations.










"There was an expectation that airfall dust would accumulate on the rover, so that its solar panels would be able to gather less electricity," said Callas. "We saw that on Pathfinder," a small rover that landed on Mars in 1997." The cold climate was also expected to be hard on the rovers' batteries, and changes in temperature from night to day would probably pop a circuit or two.


Instead, the temperatures weren't quite as tough as engineers had expected, and the rovers proved tougher. They did become filthy as the red Martian dust settled on them, reducing the sunlight on the solar panels -- but every now and then a healthy gust came along, surprising everyone on Earth by cleaning the ships off.


Click Here for Pictures: Postcards From Mars


Spirit, in hilly territory on the other side of the planet, finally got stuck in crusty soil in 2009, and its radio went silent the next year. But Opportunity, though it's had some close calls, is -- well, you remember those commercials about the Energizer bunny.


So what do you do with an aging rover on a faraway planet? You keep using it. In its first weeks, NASA said Opportunity found chemical proof that there had once been standing water on the surface of Mars -- good news if you're looking for signs that the planet could once have been friendly to life. Since then, it's been sent to other places, with rocks and soil that are probably older, and with clay that may have been left by ancient rivers.


About 20 NASA staff members still work full-time on Opportunity at the Jet Propulsion Laboratory in Pasadena, Calif. Another 60 split their time between Opportunity and other projects, such as the Curiosity rover that landed last August. About 100 scientists, doing research on Mars, pop in and out.


In a few months, Callas said, Opportunity will head to an area nicknamed Cape Tribulation. The clay there could be rich in the minerals suggestive of past life.


They haven't done much to mark the ninth anniversary or the 3,200th Martian day, just a get-together earlier this week during a previously scheduled science conference. After that, Callas said, it was back to work.


"It's like keeping your car going," he said, "without ever having a chance to change the oil."

'If the Royal Institution is sold, that's the end'









































We must find a way to save the Royal Institution from having to sell its historic London home, says Nobel laureate Harry Kroto












Why is it important to save the Royal Institution (Ri)?
It is of tremendous historical importance. It's an iconic building not just for the UK but for the world, a focal point for the public understanding of science and a laboratory where people like Lawrence Bragg and Michael Faraday did cutting-edge research. It should be a world heritage site.












Could the Ri continue to exist if the building was sold?
No. It's impossible to move it out. You can move the National Gallery or the British Library, but not the Royal Institution. The institution is the building, and the building is the institution. If the building is sold, that's the end.












How bad is the Ri's financial plight?
I don't think people fully appreciate the problems that the institution faces, partly because the financial details haven't been divulged. People are bandying about numbers that are probably significantly lower than what is needed. As far as I can see we don't have a lot of time; it looks as though the plug is being pulled.












How did it come to this?
The problem has arisen partly because the Ri got into significant debt. But it has had two years to find a strategy to convince credible sponsors and it hasn't done it.












How much money is required?
Just to keep the doors open will require at least £2 million a year, meaning an endowment of £60 million. That doesn't include paying off the debt.












In the grand scheme of things, that's not a huge amount of money.
That's correct, but the question is whether we can put together something credible to pull in that sort of funding. The only viable solution I can see is for the Royal Society to enter into some sort of partnership which would provide a level of credibility that potential funders might find acceptable.












You have started a campaign to save the Ri...
Yes. I'm doing it as a private individual, but one who knows pretty much everyone who was involved in the institution prior to 2000, when the strategy that led to this demise was put in place.












How has the response been so far?
Amazing. I've received messages from all over the world. People recognise that the institution has global significance. Many see it as a shrine to electricity, the lifeblood of the modern world. But we can't just rely on that.












What does the Ri need to do to reinvent itself?
The institution has not moved with the times as much as it could have done, by recognising it could have a global role to play rather than a provincial or UK one. Its position as a central point for UK public understanding of science is already pretty healthy, but it doesn't bring much money. So it must become the platform for 21st-century educational science outreach on a global scale, by exploiting the potential of the internet.

Keppel Corp's net profit falls 22% on-year in Q4






SINGAPORE: Falling margins from building oil rigs has hit the bottomline of Keppel Corp.

Net profit for the world's leading rig builder fell 22 per cent on-year to S$305 million in the fourth quarter last year.

Still, full year profit for the conglomerate came in 15 per cent to S$2.24 billion.

Despite lower net profit in the three months ended Dec 31, Keppel Corp still declared a final dividend of 27 cents per share.

As part of its 45th anniversary, Keppel Corp is handing out more goodies to its shareholders.

The company has proposed to distribute one Keppel REIT unit for every five Keppel Corp shares.

That is about 27.4 cents per share based on Keppel REIT's closing price of S$1.37 on Thursday.

Together with the interim dividend of 18 cents, total distribution for 2012 will be 72.4 cents per share.

Keppel Corp said the lower net profit was partly due to lower contributions from its offshore and marine unit.

Offshore and Marine's contribution was 12 per cent lower from a higher base in 2011 when margins were at record highs. It contributes to half of Keppel Corp's net profits.

"Keen rivalry from Chinese and Korean yards have suppressed prices and squeezed margins on newbuilds," said Choo Chiau Beng, chief executive officer at Keppel Corp. "In 2013, we will be completing a record of 22 newbuild units."

Analysts remained upbeat of Keppel's prospects going forward.

They say their financial results still outperformed market expectations.

Keppel Corp expects crude oil prices to stay above US$100 per barrel, supporting the need for more global exploration and production.

But global challenges like the slower US economy and the eurozone crisis from last year will continue to pose uncertainties for Keppel Corp's business.

Keppel Corp's property arm, led by the listed Keppel Land, boosted the group's earnings.

Net profit for the property division was 2.5 times higher than in 2011, offsetting the lower earnings from business in the offshore and marine, and infrastructure.

But Keppel Corp does not expect its property arm to perform better this year.

This is because recognition from sales of completed units at its development Reflections at Keppel Bay is expected to be lower this financial year.

Available today, the iOS and Android versions offer a dashboard for your Pebble watch. You start by pairing your phone or
tablet with your watch via Bluetooth. Once they've been paired, the app offers several handy features.


You can install custom watch faces onto the Pebble. You can receive notices when new software updates are available for the Pebble. You can send test messages to your watch. You can also access how-to guides and contact Pebble tech support from your iOS device.


Of course, in order to use the app, you first need to buy the watch. So, what is the Pebble watch and how do you get one?


The $150 Pebble is a smartwatch, meaning it obviously does more than just tell the time.


The watch can sync with iPhones and
Android phones to notify you of incoming calls, e-mail, instant messages, and calendar appointments. The display uses e-paper technology, so you can more easily see it in direct sunlight. The watch also has the ability to run mobile apps, once such apps become available.


Like many innovative products, the Pebble kicked off through a Kickstarter campaign, which proved to be a true money maker. Last May, the watch easily hit its goal of $100,000 in funds, then went on to generate a total of $10.2 million from eager backers.


And now the watch is finally off the assembly line. The Pebble people announced yesterday that the first 500 units are being shipped to the earliest Kickstarter backers. But more are expected soon. The company said its factory is making 800 to 1,000 Pebbles per day and is striving to reach full capacity of 2,400 a day.


People who didn't get in on the Kickstarter action and want the watch can preorder one for $150 at Pebble's Web site. But you'll naturally have to wait until the backers get theirs.

Deformed Dolphin Accepted Into New Family


In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic news).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Exterminator Charged in Pa. Doctor's Murder













An exterminator named Joseph Smith was arrested and charged today in the strangling and burning death of Philadelphia pediatrician Melissa Ketunuti.


Smith, 36, had been sent to Ketunuti's home on a service call where the two got into "some kind of argument" in Ketunuti's basement on Monday, Capt. James Clark of the Philadelphia police department said this morning.


"At her home they got into an argument. It went terribly wrong. He struck her, and knocked her to the ground," Clark said. "Immediately he jumped on top of her, started strangling her. She passed out, and then he set her body on fire."


Clark said Smith burned the woman's body "to hide evidence like DNA." He said "at some point, he bound her up." The doctor was found with her hands and feet tied behind her back.


The captain said that before today's arrest Smith's record consisted of only "minor traffic offenses."

Philadelphia Doctor's Murder Leaves Police Baffled Watch Video





Police received a call from Ketunuti's dog-walker about the house fire around 12:30 p.m. Monday, and once inside found Ketunuti with her hands and feet bound. They believe Smith hit her and strangled her with a rope, causing her to pass out, and then bound her body and set fire to it in order to destroy evidence, including DNA evidence.


Ketunuti, 35, was fully clothed and police do not believe she was sexually assaulted.


She was a doctor at Children's Hospital of Philadelphia and had lived alone in the Graduate Hospital neighborhood of the city for about three years.


Clark said that homicide detectives scoured the neighborhood for surveillance videos from nearby stores and businesses, and through the video identified the suspect.


Smith was spotted on video getting out of the vehicle and following Ketunuti to her home. The man left her home after an hour and was seen on video circling her home.


Detectives drove to Clark's home in Levittown, Pa., outside of Philadelphia where he lives with a girlfriend and her child, on Wednesday night and brought him back to the Philadelphia police station.


A silver Ford truck was towed from Smith's home, which was the same truck spotted on surveillance video Monday in Ketunuti's neighborhood, sources told ABC News affiliate WPVI.


There, he gave statements that led police to charge him with the murders, Clark said.


Smith will face charges of murder, arson, and abuse of a corpse.


Ketunuti's hospital issued a statement Tuesday that she was "a warm, caring, earnest, bright young woman with her whole future ahead of her," adding that she will be deeply missed.


"[She was] super pleasant, really nice," one neighbor said. "Just super friendly."

Pure colour mixing gets laser power



Jeff Hecht, consultant

The three coloured jets aren't what they seem. They look like fluids dyed different colours mixing to make a clear liquid. But all the water is clear: the colour comes from red, green and blue lasers. This photo won Alexander Albrecht of the University of New Mexico in Albuquerque first prize in the 2012 After Image photo contest run by Optics & Photonics News.





The colours seem to be flowing through the jets because an effect called total internal reflection is confining the laser beams. Each laser is aimed along the centre of a jet. As the jet bends, the light hits the boundary between water and air at a glancing angle, so it is reflected back into the water and travels further along it. If the light is to travel all the way down the jet, the surface of the jet must be smooth and even to keep the light and the water from breaking up in turbulence. Some light passing through the water jet scatters out of it by bouncing off water molecules, an effect called Rayleigh scattering.



Physicist Daniel Colladon first demonstrated light guiding along a water jet in 1841. Another physicist, John Tyndall, later repeated the demonstration in his popular lectures at the Royal Institution in London. The effect is credited with inspiring concepts from illuminated fountains to fibre optics.



The red, green and blue laser beams mix together to make white light because they are the same intensity and match the human eye's three colour receptors. Combining different blends of these three primary colours can produce the whole range of colour visible to the human eye, including colours such as pink and brown which are not in the rainbow or solar spectrum. Video displays produce images in the same way, by modulating the brightness of tiny red, green and blue emitters across the whole screen.

Japan presses Algeria for answers as toll hits nine






ALGIERS: A senior Japanese official met Algeria's prime minister on Wednesday to press for an explanation of the gas plant siege, as Tokyo confirmed the deaths of two more nationals, taking its toll to nine.

Senior Vice Foreign Minister Shunichi Suzuki arrived aboard a government jet that is to repatriate the bodies of those known to have been killed in the hostage crisis, along with the seven Japanese who survived.

Tokyo announced late Wednesday that it knew for sure that nine Japanese were killed after Islamist gunmen overran the desert facility. One Japanese citizen remains unaccounted for.

"Unfortunately, we have been able to confirm two more deaths," said Chief Cabinet Secretary Yoshihide Suga. "The Japanese government expresses sincere condolences to the families and people concerned."

"The use of violence cannot be tolerated for any reason. We firmly condemn acts of terror," he said adding the government would do its utmost to confirm the fate of the final missing person.

Seventeen Japanese were at the facility in In Amenas when jihadists struck last Wednesday at the start of a four-day siege that left dozens of foreigners dead. Seven of them made it to safety.

Suzuki carried a letter to Algerian President Abdelaziz Bouteflika from Japan's Prime Minister Shinzo Abe, Suga told reporters in Tokyo earlier.

As well as Prime Minister Abdelmalek Saleki, Suzuki also met Foreign Minister Mourad Medelci, Japan's Kyodo News reported, citing Tokyo's foreign ministry.

Japan has asked Algeria to fully investigate events at the gas plant and exactly how individuals died, Suga said in Tokyo.

"Algeria has promised to cooperate as much as possible," he said.

Algeria has said 37 foreigners of eight different nationalities and an Algerian were killed in the siege, which ended on Saturday.

Several people are still missing and the bodies of others are so badly charred that they have not been identified.

Wednesday's visit came as it emerged that Britain, Japan, the United States and other countries whose nationals were caught up in the events at the In Amenas plant issued a joint demarche to Algeria last Friday.

A demarche is a formal diplomatic move in which a country's stance is conveyed in person -- rather than by note -- to another government.

In a conference telephone call, vice foreign minister Minoru Kiuchi told foreign minister Medelci that Tokyo wanted Algiers to do all it could to protect captives.

"Japan is strongly concerned about acts that put the lives of the hostages at risk, and it is regrettable that the Algerian government pressed military rescue operations," he said, according to the foreign ministry.

Japan was among the more forthright of nations as the hostage crisis unfolded, summoning Algiers' ambassador to demand answers and to push for military restraint as armed forces surrounded the plant.

The Japanese plane's arrival in Algiers came as Tokyo announced it was shutting its embassy in neighbouring Mali, evacuating staff and urging its nationals there to leave because of the deteriorating security situation.

The kidnappers claimed they launched their attack in protest at Algeria's complicity in a French military campaign against Islamists in Mali.

The Japanese death toll in Algeria -- the highest in a terror attack since Al-Qaeda crashed airliners into New York's Twin Towers when 24 Japanese died -- has shaken a country not accustomed to its citizens being made targets abroad.

There has been blanket media coverage of events half a world away and anguished demands for more to be done to protect Japanese working in trouble spots, including beefing up spy networks.

Kyodo on Wednesday said Suga indicated Tokyo's willingness to consider increasing the number of defence attaches at Japanese embassies to strengthen the country's ability to gather information.

"I am aware of the need. We need to think about the most effective (crisis-response) measures," Suga said.

Apple, Google, others agreed not to poach workers, reveal e-mails



Apple, Google, Intel, Adobe, and other companies had agreements in place during the mid-2000s not to steal employees from each other and other technology players.


A series of e-mails posted today by The Verge point to a paper trail of non-poaching agreements among a variety of companies.


The revelation follows a civil lawsuit filed in 2011 by five workers against Apple, Google, and others alleging that the companies purposely tried to keep down wages through non-poaching agreements.


In one case made public yesterday, then Palm CEO Edward Colligan said he received a call from Apple CEO Steve Jobs in 2007 suggesting a non-poaching agreement between the two companies. After pointing out that such an arrangement was "likely illegal," Colligan said Jobs suggested that if Palm didn't agree, Palm could face patent infringement lawsuits from Apple.


But the reported exchange between Jobs and Colligan seems to be the tip of the iceberg.


In one e-mail displayed by the Verge, Jobs asked Google CEO Eric Schmidt to stop recruting people from
Apple's iPod group.


In another message, a senior staffing stategist at Google told Schmidt that a recruiter who tried to hire an Apple employee was to be fired. Schmidt's response? "I would prefer that Omid do it verbally since I don't want to create a paper trail over which we can be sued later? Not sure about this."


Other e-mails traveled throughout Silicon Valley. A message from Intel CEO Paul Otellini points to an agreement with Google but cautions that "we have nothing signed. We have a handshake 'no-recruit' between eric and myself. I would not like this broadly known."


A memo from Intel says that people from Pixar cannot be recruited, adding that if someone from Pixar applies for a job, the CEO of Pixar needs to be contacted for approval.


Some companies actually maintained lists of firms that were off limits for talent acquisition.


A document from Adobe warned staffers not to recruit workers from Apple, Bell Canada, EMC, SAP, and others. An Apple document placed Microsoft, Google, Intel, Pixar, and a host of others on the do-not-call list. A Google document cautioned against contacting potential hires from Intel, Apple, PayPal, Comcast, and Genentech, saying that Google has "special agreements" with these companies.



The civil suit is being weighed by Judge Lucy Koh to determine if it can move forward as a class-action suit, says Reuters. If so, that could pave the wave for a bigger settlement.


Attorneys for the plantiffs claim damages could reach hundreds of millions of dollars. But Koh said that analysis had "holes," Reuters added.


In 2010, Apple, Adobe, Google, Intel, Intuit, and Pixar settled with the Justice Department by promising to end non-poaching agreements.


CNET contacted Apple, Intel, and Google for comment and will update the story if we receive any information.

Pictures: Trout vs. Trout in Yellowstone Lake

Photograph by Jay Fleming

Without aggressive management, the population of Yellowstone cutthroats could be decimated. To suppress the population of lake trout, the National Park Service engaged a contract fishing company to net them. Cutthroats are removed carefully from the traps and thrown back. Lake trout are removed and killed. Last year about 300,000 of the non-native intruders were taken from the lake.

Clinton Says Budget Cuts Undermine Security













An energized Secretary of State Hillary Clinton stood her ground today, telling the Senate Foreign Relations Committee that she has overseen plans to secure diplomatic outposts around the world while cuts in State Department funding undermine those efforts.


Citing a report by the department's Accountability Review Board on the security failures that led to the deaths of four Americans in Benghazi, Libya, during an attack last year, Clinton said the board is pushing for an increase in funding to facilities of more than $2 billion per year.


"Consistent shortfalls have required the department to prioritize available funding out of security accounts," Clinton told the Senate this morning, while again taking responsibility for the Benghazi attack. "And I will be the first to say that the prioritization process was at times imperfect, but as the ARB said, the funds provided were inadequate. So we need to work together to overcome that."


Clinton, showing little effect from her recent illnesses, choked up earlier in discussing the Benghazi attack.


"I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews," Clinton said this morning, her voice growing hoarse with emotion. "I put my arms around the mothers and fathers, sisters and brothers, sons and daughters."


The outgoing secretary of state was the only witness to giving long-awaited testimony before the Foreign Relations Committee this morning, and will appear before the House Foreign Affairs Committee at 2 p.m.

The secretary, who postponed her testimony in December, started today by giving context to the terrorist attack.


"Any clear-eyed examination of this matter must begin with this sobering fact," Clinton began. "Since 1988, there have been 19 Accountability Review Boards investigating attacks on American diplomats and their facilities."


But the secretary did not deny her role in the failures, saying that as secretary of state, she has "no higher priority and no greater responsibility" than protecting American diplomats abroad like those killed in Benghazi.


"As I have said many times, I take responsibility, and nobody is more committed to getting this right," Clinton said. "I am determined to leave the State Department and our country safer, stronger and more secure."


Among the steps Clinton has taken, she said, is to "elevate the discussion and the decision-making to make sure there's not any" suggestions that get missed, as there were in this case.


Clinton testified that the United States needs to be able to "chew gum and walk at the same time," working to shore up its fiscal situation while also strengthening security, and she refuted the idea that across-the-board cuts slated to take place in March, commonly referred to as sequestration, were the way to do that.


"Now sequestration will be very damaging to the State Department and USAID if it does come to pass, because it throws the baby out with the bath," Clinton said, referring to the United States Agency for International Development, which administers civilian foreign aid.


While the State Department does need to make cuts in certain areas, "there are also a lot of very essential programs … that we can't afford to cut more of," she added.


More than four months have passed since the attack killed U.S. Ambassador Christopher Stevens and three other Americans in Libya. These meetings, during which Clinton discussed the report on State Department security failures by the Accountability Review Board, were postponed because of her recent illness.


Clinton told the Senate that the State Department is on track to have 85 percent of action items based on the recommendations in the Accountability Review Board report accomplished by March, with some already implemented.

Did Mars hide life in its watery pockets?








































Signs of the most recent life on Mars may have sprung up from underground. Because they would have been protected from harsh conditions on the surface, such as radiation, pockets of underground water may be where Martian life existed most recently.













Sulphates, made through interaction with briny water, lie all over Mars. As water underground is also briny, this suggested frequent upwellings.












But Joseph Michalski of the Planetary Science Institute in Tucson, Arizona, and colleagues found that most basins, where groundwater would have pooled, are free of sulphates. The deep McLaughlin crater is instead rich in clays and carbonates which also formed through contact with water.











Search those basins













As water bearing these minerals would be more life-friendly than sulphate-rich water, which is more acidic, McLaughlin may be a good place to look for signs of life that pooled there from underground.












"The stuff we see in McLaughlin could have been very good at preserving life and could have been habitable," says Michalski.












He suggests that future Mars missions should search such basins for signs of habitability, such as the organic molecules that NASA's Curiosity Mars rover is currently seeking. "Perhaps we need to re-emphasise and redirect our attention to the subsurface environments," Michalski says.












Horton Newsom at the University of New Mexico at Albuquerque, who was not involved in the new work and who works on Curiosity, thinks the idea sounds reasonable. "Given the low elevation location of McLaughlin crater… it is quite reasonable that it was flooded by deep groundwater."

SGX's Q2 net profit rises 17% to S$76m






SINGAPORE : Rising interest in derivatives trading helped lift earnings for the Singapore Exchange (SGX) last quarter.

Asia's second-largest bourse operator reported a 17 per cent on-year rise in second-quarter net profit to S$76 million.

It also attracted a large number of new bond listings in the same quarter.

Derivatives trading has been the star performer in SGX.

Over the October to December quarter, derivatives daily average volume on SGX hit a record of 358,532 contracts, up 30 per cent on-year.

This was supported by rising trading interests in China A50 futures and Japan Nikkei 225 options.

Not to be undone, the securities market performed well too.

Its daily average volume rose 8 per cent for the quarter to hit a trading value of S$1.2 billion.

This translates to a revenue of S$58 million for the securities business segment.

SGX said the better performance was due to improvements in investor sentiment following stability over the Europe debt situation and improved US economy.

Magnus Bocker, chief executive officer of Singapore Exchange, said: "We should remember the enormous amount of liquidity in the market. Not so much in the equity market, but actually more in the fixed income and currency markets, and with chasing yields and lot of very successful and growing companies, I think we can all expect this sentiment to continue. I think we can expect more flows into securities."

Some analysts are bullish on SGX's prospects going forward.

The said the improved investment climate globally may benefit the exchange operator.

Ken Ang, investment analyst at Phillip Securities Research, said: "SGX is very well placed to benefit from this increasing attractiveness of the equity market and therefore resulting in increase in trading value."

SGX attracted eight new listings in its second quarter - raising S$798.9 million.

While the number seems small, it came amid declines in the global initial public offering (IPO) market.

In 2012, global IPO volumes fell 27 per cent, with the lowest level of funds raised since 2009.

Kenneth Ng, head of Singapore research at CIMB Research, said: "I think while that (derivative) is great and that diversified the revenue of SGX, SGX still has a rather pertinent problem of trying to increase the security turnover velocity and value by retail initiatives, attracting listings and so forth."

Apart from seeking more IPOs, SGX also attracted some 90 new bond listings, raising S$39.7 billion for the quarter.

Bigger iPhone still coming -- just not this year, report says




CNET

iPhone 5



(Credit:
CNET)


In an about-face, Digitimes -- the purveyor of numerous Apple rumors, some of which have been true -- says not to get your hopes up for an even larger version of the iPhone. At least not this year.


The tech news site says Apple's still working on one, but that it won't come in the second half of this year, as it excitedly reported earlier this month. That report made waves after claiming Apple was working on a low-cost model with an even larger screen than the 4-inch display found on the
iPhone 5.


"Previously it was said that Apple would release a lower-cost version of its iPhone with a bigger screen in 2013," Digitimes said this morning. "But the sources claimed that Apple is indeed developing an iPhone with a bigger screen, but that will not be among the models to be lancuhed [sic] this year."


The reasoning behind the move, the updated report offers, is supply of the screens with larger displays creating possible production issues.


The report follows one from Chinese language Commercial Times yesterday, which said Apple has a low-cost, 4.8-inch iPhone model in the hopper dubbed the "iPhone Math." Jefferies analyst Peter Misek, who watches Apple's supply chain closely, put out a note to investors this morning agreeing with that possibility.


"Our checks agree three different models are scheduled for launch in 2013 but disagree on the details," Misek said. "We believe a lower-cost 4.3" iPhone and multi-color 4" iPhone 5S will launch in June/July. Additionally, we believe a 4.8" iPhone model is scheduled for the end of October. We do not know what this phone will be called and think 'Math' might be a mistranslation or a code name."


Apple currently sells three different models of the iPhone, but has only ever introduced one model at a time, choosing to sell the older model at a lower price. There were numerous rumors ahead of the
iPhone 4S in 2011 that Apple planned to change that with the simultaneous release of a 4S and the 5, something that proved to be wrong.

Newly Discovered Nebula Looks Like a Manatee


It's a bird, it's a plane, it's ... a manatee? The National Radio Astronomy Observatory (NRAO) believes that a gas cloud in the constellation Aquila bears an uncanny resemblance to the endangered aquatic mammal.

Heidi Winter, executive assistant to NRAO's director, first noticed the similarity. And Tania Burchell, an NRAO media producer who used to work in manatee conservation, quickly saw it as "a wonderful opportunity to bridge two worlds—biology and astronomy."

The cloud, or nebula, which is named W50, has more in common with manatees than just its shape. It is the remnant of a star explosion from 20,000 years ago. Particle beams that shoot from the explosion's center, where a star and a black hole orbit each other, form a spiral pattern resembling scars.

Manatees also bear scars. "Around 80 percent of manatees in Florida have visible scarring," said Michael Lusk, manager of Crystal River National Wildlife Refuge. Because manatees prefer shallow water, collisions with boat propellers are frequent.

The resemblance continues. Like the "sea cow," which can blend into murky water, the nebula is hard to spot. It's approximately 18,000 light-years away, so only one bright arc can be seen by the human eye. Astronomers first saw the ghostly nebula with a telescope that collects a kind of light that radiates at longer wavelengths called radio waves.

W50's new nickname, the Manatee Nebula, and its first photos were unveiled January 19 at the Florida Manatee Festival. "People have an underlying love for the natural world—sky or sea," said Burchell. "We're human beings on this planet, looking up or looking down."

The event marks the 40th anniversary of the Endangered Species Act, which aims to protect critical habitats. Florida's manatee population has risen from around 700 in the 1970s to 5,000 today, and the U.S. Fish and Wildlife Service is considering reclassifying the species from endangered to threatened.

Group Finds More Fake Ingredients in Popular Foods













It's what we expect as shoppers—what's in the food will be displayed on the label.


But a new scientific examination by the non-profit food fraud detectives the U.S. Pharmacopeial Convention (USP), discovered rising numbers of fake ingredients in products from olive oil to spices to fruit juice.


"Food products are not always what they purport to be," Markus Lipp, senior director for Food Standards for the independent lab in Maryland, told ABC News.


In a new database to be released Wednesday, and obtained exclusively by ABC News today, USP warns consumers, the FDA and manufacturers that the amount of food fraud they found is up by 60 percent this year.


USP, a scientific nonprofit that according to their website "sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide" first released the Food Fraud Database in April 2012.


The organization examined more than 1,300 published studies and media reports from 1980-2010. The update to the database includes nearly 800 new records, nearly all published in 2011 and 2012.


Among the most popular targets for unscrupulous food suppliers? Pomegranate juice, which is often diluted with grape or pear juice.


"Pomegranate juice is a high-value ingredient and a high-priced ingredient, and adulteration appears to be widespread," Lipp said. "It can be adulterated with other food juices…additional sugar, or just water and sugar."






Lipp added that there have also been reports of completely "synthetic pomegranate juice" that didn't contain any traces of the real juice.


USP tells ABC News that liquids and ground foods in general are the easiest to tamper with:

  • Olive oil: often diluted with cheaper oils

  • Lemon juice: cheapened with water and sugar

  • Tea: diluted with fillers like lawn grass or fern leaves

  • Spices: like paprika or saffron adulterated with dangerous food colorings that mimic the colors


Milk, honey, coffee and syrup are also listed by the USP as being highly adulterated products.


Also high on the list: seafood. The number one fake being escolar, an oily fish that can cause stomach problems, being mislabeled as white tuna or albacore, frequently found on sushi menus.


National Consumers League did its own testing on lemon juice just this past year and found four different products labeled 100 percent lemon juice were far from pure.


"One had 10 percent lemon juice, it said it had 100 percent, another had 15 percent lemon juice, another...had 25 percent, and the last one had 35 percent lemon juice," Sally Greenberg, Executive Director for the National Consumers League said. "And they were all labeled 100 percent lemon juice."


Greenberg explains there are indications to help consumers pick the faux from the food.


"In a bottle of olive oil if there's a dark bottle, does it have the date that it was harvested?" she said. While other products, such as honey or lemon juice, are more difficult to discern, if the price is "too good to be true" it probably is.


"$5.50, that's pretty cheap for extra virgin olive oil," Greenberg said. "And something that should raise some eyebrows for consumers."


Many of the products USP found to be adulterated are those that would be more expensive or research intensive in its production.
"Pomegranate juice is expensive because there is little juice in a pomegranate," Lipp said.

Twitter reveals how Higgs gossip reached fever pitch



Jacob Aron, reporter



Anyone who fondly remembers the heady days in early July 2012 when the discovery of the Higgs boson was hotly anticipated, and eventually announced, can now relive the thrilling experience thanks to an analysis of Higgs-related traffic on Twitter.



The traffic - amounting to more than 1 million tweets - provides a neat reflection of real-world excitement, starting with rumours of the elusive particle, and eventually erupting into a buzz of Higgsteria with global reach. The data might even help marketers predict how news about their products will spread on Twitter.



This video shows how the rate of tweets changed per hour over the key period, in various locations around the world.








The discovery in July of the long-sought Higgs boson, or at least something very much like it, was easily the biggest science story of 2012. Manlio De Domenico of the University of Birmingham, UK, and colleagues, who study the relationships between social and geographic networks, saw it as a unique opportunity to gather data.



Rumour watch



Normally such Twitter data sets are gathered retrospectively, but as a former physicist, De Domenico had an advantage. "I was aware something big about the Higgs was being presented, so I proposed to monitor the progress of the rumours."



Using software to monitor for the words "lhc", "cern", "boson" and "higgs", the group began collecting tweets on 1 July, when rumours of a particle discovery were already beginning and anticipation was mounting. The researchers continued their monitoring beyond the particle announcement at CERN, near Geneva, Switzerland, on 4 July, right up until the 7th.

The rate of tweets per hour on 1 July was just 36. This grew in the following days and spiked on 4 July when it reached a peak of about 36,000 an hour (see below).



fig-2.jpg

To help make sense of their data, the researchers split the tweets into four time periods. The first covered the initial Higgs rumours, the second included the final release of Higgs data from the already-defunct Tevatron collider in Batavia, Illinois, which once hoped to beat the LHC to the Higgs discovery, the third covered further rumours and the fourth spanned the actual announcement of the Higgs and the aftermath.



The number of users joining the Higgs conversation changed dramatically over these four periods. In the graph below, you can see that although it looks as if there is just a small jump following CERN's announcement, the graph uses a logarithmic scale, which means that only 10 per cent of users who tweeted about the Higgs were doing so before the announcement.

Analysing Twitter users' locations revealed how the Higgs conversation changed over the seven monitored days. Initially, the conversation seemed localised, with consecutive Higgs tweets most likely to be sent by users living 20 kilometres apart. However, by the time of the announcement, consecutive tweets were equally likely to come from anywhere in the world.



Unsurprisingly, the official CERN Twitter account got the most retweets during the monitored period. Second place was less predictable, however, going to Colin Eberhardt, a software consultant who still has relatively few followers.



Eberhardt managed to strike a nerve with one of his tweets - winning the prize for the single most-shared tweet. It read: "Possibly the biggest scientific discovery of our time, the #Higgs Boson, announced in glorious MS Comic Sans Font", making reference to the odd choice of font used in the presentation from ATLAS, one of the two LHC experiments that discovered the Higgs.



No hard feelings



The New Scientist account @newscientist was beaten to third place by just one retweet by University of Manchester physicist and TV presenter Brian Cox.



As well as providing a neat anatomy of a historical event, the work helps us understand how other topics spread on Twitter, say De Domenico and his team. They used the data to create a mathematical model that uses the number of newly active Higgs tweeters at any given moment to predict the number that will emerge at future points in time.



Such information could be useful for people who want to keep a message spreading, such as marketers. "If you want to keep interest for a certain product going, you might want to estimate where and when to tweet," he says.



In some ways, it seems the announcement of a new particle isn't very different from the launch of a new product.

Football: Cardiff sign Sunderland's Campbell






LONDON: Championship leaders Cardiff have signed striker Fraizer Campbell on a three-and-a-half-year deal from Premier League club Sunderland, the Welsh club announced Monday.

The 25-year-old England international scored just 10 goals in 72 appearances for Sunderland after joining the north-east side from Manchester United.

Campbell came through the Old Trafford youth system before signing professional forms with English giants United in 2006.

He had loan spells with Antwerp and Tottenham Hotspur but made his mark at Hull, scoring 15 goals in 32 starts and helping them reach English football's top flight.

After recovering from injury, he made his full England debut against the Netherlands 11 months ago but has scored just once in 15 appearances this season for the Black Cats.

Despite Cardiff sitting 10 points clear at the top of the Championship and leading the charge for promotion to the lucrative Premier League, none of their strikers have been in the goals this term.

Heidar Helgusson is Cardiff's top scorer with just seven goals in 24 starts.

RIM CEO says licensing of BlackBerry 10 'conceivable'

Research In Motion will launch devices running BlackBerry 10 at the end of the month, but the handset maker is still playing with the idea of licensing its new operating system to other manufacturers.


When asked whether RIM might license the new platform as Microsoft did with Windows Phone, RIM CEO Thorsten Heins told German newspaper Die Welt that it's not out of the realm of possibility.


"Before you licensed the software, you must show that the platform has a large potential," he said, "First we have to fulfill our promises. If such proof, a licensing is conceivable."


Licensing would allow third-party hardware makers to put the new OS on non-RIM devices. RIM has a lot riding on BlackBerry 10, which the company hopes will reinvigorate the brand. After some delay, RIM is expected to unveil handsets fort the new platform next week in a multiple-city debut.

When asked about the delay, Heins said the company's goal was to create a solid platform that would last a decade.




"We have taken the time to build a platform that is future-proof for the next ten years," he said. "Our aim is not only to smartphones, but also to the use, for example, in
cars that will be in the future increasingly networked. We see with BlackBerry 10 completely new areas of growth."


The company has been struggling to bring back lost market share and sales for its once popular BlackBerry devices, but it's not having much luck in an industry ruled by Apple and
Android, which Google has had great success licensing to third-party hardware makers. The company announced a broad restructuring last year and is rumored to be considering a plan to split in two, separating its handset division from its messaging network and selling off the struggling BlackBerry hardware business

Attack at Algeria Gas Plant Heralds New Risks for Energy Development



The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")


As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")


"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")


"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.


On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.


"A Hot Place to Drill"


The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.


Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.


Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.


Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.


"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."
