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.

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.

Pebble smartwatch app clocks in for iOS, Android



Owners of the new Pebble smartwatch can now download an iOS or Android app to get even more out of the watch.


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."
