Extreme life might be visible on colourful exoplanets








































Lichens and algae could be the first life forms we find on Earth-like exoplanets, by looking for their light signatures in a planet's distinctive colouring.












Astronomers have found several rocky worlds in the habitable zone, the region around a star where liquid water can exist on a planet's surface, and many more are thought to exist. As telescopes get more sensitive, we should be able to collect light reflected off such planets and look for clues to their surface conditions.












Seen from space, Earth gives off a large amount of near-infrared light, which is reflecting off the chlorophyll in plants. We might see a similar "red edge" on distant exoplanets if they also host green vegetation.













But Siddharth Hegde and Lisa Kaltenegger of the Max Planck Institute for Astronomy in Heidelberg, Germany, think it is possible that many rocky worlds will have extreme heat, dryness or acidity, and that hardier life forms will dominate their surfaces. So what would these organisms look like from a distance?











Patterns of life













To find out the pair looked at the light reflected by some of Earth's more extreme life forms: lichens in arid regions, bacterial mats in very hot water and red algae in acid mine drainage. They calculated that seen from afar each type of organism would create a unique colour pattern. Lichens, for instance, appear more yellow than the algae or bacteria.












Finding these patterns wouldn't necessarily mean life is present, but it could be a step towards narrowing down exoplanets for more detailed searches, the authors say.












It's an attractive idea, says Nicolas Cowan of Northwestern University in Evanston, Illinois, and it is far more likely that a given planet would contain microbial life than trees. But the work has its limits, he cautions. For instance, atmospheres on other planets may be very different from our own and could scatter light in ways we wouldn't expect.












"Nature may be more creative than our little corner of the cosmos would have us believe," Cowan says.

Changi Airport heralds in the LNY with auspicious floral displays






SINGAPORE: Changi Airport is all set to herald in the Lunar New Year decked in festive finery.

In recent years, florists have started to dye the white flowers in a variety of colours including red, blue and orange.

But horticulturalists said they've mostly hung on to tradition.

Manager at Changi Airport Operations Planning, Look-Tan Hwee Sung said: "Like hydrangea, in Chinese is called 'xiu jiu hua', it represents love. 'Fong mei' is related to 'fong huang', which means 'phoenix tail', which is related to prosperity. In the olden days, 'fong mei' was always in the royal family and things like that."

Most of the plants were grown locally or imported from the Cameron Highlands. And it took the 10-men horticulture team two months to select and design the flora displays.

Look-Tan Hwee Sung said: "The flowers are in full bloom because throughout the propagation period we feed them different types of fertiliser. Either you get cuttings or seed sowings, but we'll target for the date for it to bloom."

The 5th day of the Lunar New Year falls on 14 February which happens to be Valentines Day. So they've added a touch of romance to the terminals, along with Singapore's favourite couple - Kai Kai and Jia Jia.

The displays will be around until 6 March before making way for the next festive season.

Apple and the iWatch conundrum



Will Apple ever make an iWatch?



(Credit:
Sarah Tew/CNET)



Ever since the sixth-generation iPod Nano, lots of people have thought that Apple making its own branded watch is not merely a smart potential move but simply a matter of time. No matter what some have recently argued, I doubt, however, that today's Apple is hungry enough to create the fabled iWatch device.



I've been covering the technology beat long enough to feel, no, smell certain shifts in the gadget market. I'm talking about those cycles when a new product category springs up from nowhere and first seems like a completely goofy notion. Soon after, the segment really heats up with scores of companies jumping into the fray to make a quick buck.



Traditionally, if Apple senses a legitimate opportunity it steps in at the right moment after figuring out the secret to success and sucks the air right out of the market.
Tablets and MP3 players existed well before Apple launched the
iPod and iPad, but their arrival completely transformed the playing field. Remember music players from Creative Labs, Rio, or even Microsoft's clunky Windows Tablet PCs?


I'm getting the same tingling sensation right now from smartwatches. At
CES in January the sleeper hit of the show was wearable tech, essentially devices you could strap or clip to yourself as you would an accessory or article of clothing. A lot of smartwatches, fitness bands, or some hybrid of the two, were talked up at the conference.

These included everything from the long-awaited and crowd-funded Pebble and the Dick Tracy/007-inspired Martian Passport Watch to the Fitbit Flex fitness tracker and the Basis Band. When you factor in the success of the Nike FuelBand, Nike being a company Apple has partnered with in the past to create fitness products, I'd say the time is ripe for Apple to swoop in for the kill.


Chat through the Martian Passport like a speakerphone.

This is a move the Cupertino company used to accomplish without breaking a sweat. Apple has the knack of catching the competition completely flat-footed, surprising since many already had a big head start. The iPhone is a perfect example. Smartphones had existed for years but the iPhone sounded the death knell for Microsoft's struggling Windows Mobile products -- trust me, I was saddled with a T-Mobile Wing at the time. The Sidekick and a legion of keyboarded feature phones suffered the same fate.


I'm afraid Apple hasn't demonstrated its signature ferocity in recent years. We haven't seen a truly disruptive product from the company since the first iPad. Every noteworthy hardware release since then has been evolutionary and incremental, not transformative. The iPad Mini is simply a smaller iPad, while the iPhone 5 essentially increased the screen from 3.7 to 4 inches. Its A6 processor is also dual-core where many Android CPUs have gone to full quad-core and it received 4G LTE well after its rivals.

What Apple needs here is true out-of-the-box action to quell the doubters at large and on Wall Street. A serious example of nonlinear thinking that matches the creation of the iPod, iPhone, and iPad. Something that would merge multiple gadgets and applications into something entirely new or perhaps clean up the confused mess other manufacturers tout as useful gadgets. Something like a fabulous, shiny Apple iWatch.

Northeast Shuts Down as Blizzard Batters Millions













A blizzard of possibly historic proportions battered the Northeast Friday into Saturday, and forecasters feared as much as two feet of snow and strong winds could shut down densely populated cities such as New York and Boston, where cars were ordered off the streets.


State officials declared states of emergencies throughout the region, and utilities estimated more than a half-million customers were without power by late Friday night.


Some wondered if the storm could top Boston's all-time single-storm snowfall record of 27.6 inches, set in 2003.


By 9 p.m. Friday, according to the National Weather Service, the storm was spinning off the coast of Long Island, N.Y., and expected to move north-northeastward past New England's coast before its effects tapered off on Saturday afternoon.


"Storm total snowfall accumulations of 1 to 2 feet ... with locally higher amounts are possible across much of the Northeast," the National Weather Service said. "The heaviest snow is forecast to fall across parts of eastern Massachusetts ... Connecticut and Rhode Island where snowfall amounts higher than two feet are possible. In addition to the heavy snowfall ... wind gusts as high as 70 mph are possible ... especially near the coasts."


By 9 p.m. Friday, parts of Connecticut and New York had the highest actual snowfall totals listed by the National Weather Service, with 13 inches measured in Ogdensburg and East Setaukey, N.Y., and Lisbon and North Branford, Conn.


Peak wind gusts included a 71-mph measurement in Buzzards Bay, Mass., the National Weather Service said.


Power outages also were reported across the region. As of 11 p.m. Friday, for instance, approximately 300,000 Massachusetts customers were without power, ABC News station WCVB reported. Utilities also reported approximately 170,000 without power in Rhode Island, 30,000 in Connecticut and nearly 20,000 in New York.


The blizzard conditions came together after a storm from the west joined forces with one from the south to form a nor'easter.

Weather Forecast: Blizzard Headed for Northeast Watch Video





The storm showed the potential for such ferocity that, before it even hit with full force, Massachusetts Gov. Deval Patrick declared a state of emergency Friday afternoon and signed an executive order banning vehicular traffic on roads in his state effective at 4 p.m. ET. It was believed that the last time the state enacted such a ban was during the blizzard of 1978. Violating the ban could result in a penalty of up to a year in jail and a $500 fine.


"[It] could definitely be a historic winter storm for the Northeast," said Adrienne Leptich of the National Weather Service in Upton, N.Y. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."


Airlines began shutting down operations Friday afternoon at major airports in the New York area as well as in Boston, Portland, Maine, Providence, R.I., and other Northeastern airports. By early evening Friday, more than 4,300 flights had been cancelled on Friday and Saturday, according to FlightAware. Airlines hoped to resume flights by Saturday afternoon, though normal schedules were not expected until Sunday.


The snow fell heavily Friday afternoon in New York City. Mayor Michael Bloomberg said clearing the roads was his main concern, and the city readied 1,700 snow plows and 250,000 tons of salt to clear the streets.


New York City was expecting up to 14 inches of snow, which started falling early this morning, though the heaviest amounts were expected to fall at night and into Saturday. Wind gusts of 55 mph were expected in New York City.


"Stay off the city streets. Stay out of your cars and stay at home while the worst of the storm is on us," Bloomberg said Friday.


Connecticut Gov. Dannel P. Malloy declared a state of emergency, deploying National Guard troops across the state to assist in rescues and other emergencies. Schools and state courthouses were closed, and all flights after 1:30 p.m. at Bradley Airport, north of Hartford, Conn., were cancelled. The state's largest utility companies planned for the possibility that 30 percent of customers -- more than 400,000 homes and businesses -- would lose power.


Malloy also directed drivers to stay off the state's major highways.


"Please stay off of 95, 91, 84, Merritt Parkway and any other limited-access road in the state," he said Friday evening.


PHOTOS: Northeast Braces for Snowstorm


Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today.


"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.


On Friday, Menino applauded the public's response.


"I'm very pleased with the compliance with the snow emergency," he said. "You drive down some of the roadways, you don't see one car."


Friday evening, Gov. Patrick also applauded the public's cooperation with the statewide vehicle ban, noting the clear roads were helping utility crews get their work done.


"It's been a great, great help and I thank everyone," Patrick said. "I know it's been an imposition."


As of 4:30 p.m. Friday, according to the Department of Defense, 837 National Guard soldiers and airmen under state control had been activated in Connecticut, Massachusetts and New York in anticipation of the storm -- 552 in Massachusetts, 235 in Connecticut and 50 in New York. The extra hands were helping with roadways, transportation, making wellness checks on residents and other emergency services.


Beach erosion and coastal flooding was possible from New Jersey to Long Island, N.Y., and into New England coastal areas. It was feared some waves off the coast could reach more than 20 feet.

Zoologger: 'It's a boy!' Monkey midwife delivers baby






















Zoologger is our weekly column highlighting extraordinary animals – and occasionally other organisms – from around the world






















Species: Rhinopithecus bieti
Habitat: Evergreen forests in an isolated mountainous area of south-west China












Humans aren't built for giving birth. Babies' heads are big to accommodate their big brains, but the mother's hips are small because they walk upright. As a result, birth takes hours and is extremely painful – and midwives almost always help out.












Other animals may find birth difficult, particularly if the babies have been gestating for a long time and have grown large. Nevertheless, most mammals have it easier than humans. Monkeys give birth in less than ten minutes.












So it is a surprise that female black snub-nosed monkeys may be assisted by "midwives" when they give birth. This behaviour has only been seen once in this species, but it suggests that it's not just human mothers that need help giving birth.












Black snub-nosed monkeys live in societies called bands, which can be over 400 strong. Each is divided into smaller groups of around 10 monkeys. Most groups contain one male and several females plus offspring, but there are also all-male groups.












Wen Xiao of Dali University in Yunnan, China, and colleagues have been observing black snub-nosed monkeys in the province for years, but had never seen one give birth: the monkeys normally deliver at night. Then on 18 March last year, they got lucky.











Rhododendron birth













A female monkey gave birth to her first infant within fifteen minutes late one morning. While sitting in a rhododendron tree, she began twisting her body and calling faintly. After 10 minutes she started screaming, and then another female climbed up the tree. She was an experienced mother, and sat beside the labouring female while the crown of the infant's head appeared. Once the head was fully exposed, the "midwife" pulled the baby out with both hands and ripped open the birth membranes.












Within a minute, the mother had reclaimed the infant from the midwife, severed the umbilical cord, and begun eating the placenta. A few minutes later, the midwife went back down to the forest floor to forage.












"This is a fairly rare observation," says Sarah Turner of McGill University in Montreal, Canada, who was not involved in the Yunnan study. She says female monkeys often pull their babies out themselves, and the midwife may have adapted this behaviour. "It's hard to know what's going on in her head," says Turner, but it seems she was genuinely helping.











That could be because female black snub-nosed monkeys tend to stay in the group they were born in. As a result, the females in a group are likely to be closely related and to have strong social bonds. Animals often help their relatives because doing so preserves their own genes, a phenomenon called kin selection.













The juvenile females in the group watched the birth closely, and may have picked up a few tips. Turner says many primates remain with their groups while giving birth, giving juveniles a chance to learn.











Survival aid













In a human childbirth, having help on hand can be vitally important should things go wrong, Wen notes. "The assistance means the infant has a better chance of surviving," he says. There could be a similar benefit for monkeys aided by a midwife.












But primates, with the exception of humans, rarely help each other give birth. In one case, a male cottontop tamarin was seen pulling at his infant's shoulders until they emerged. Another report claims that a female capped langur was groomed by other females during birth, perhaps in an attempt to ease her distress.












While primates generally give birth unassisted, other creatures get more help. In possibly the cutest observation in all of natural history, male Djungarian hamsters regularly assist with deliveries, pulling infants out with their front paws and incisors.

Asian markets rise but Tokyo hit by strong yen






HONG KONG : Asian shares mostly rose on Friday following a sell-off in the previous session, but Tokyo was hit by a stronger yen and data showing Japan suffered its lowest current account surplus in nearly 30 years.

Data showing China's trade surplus had risen more than expected provided extra buying support, adding to a recent trend of improvement in the world's number two economy.

Tokyo dived 1.80 per cent, or 203.91 points, to 11,153.16 while Sydney gained 0.72 per cent, or 35.6 points, to 4,971.3 and Seoul closed up 0.99 per cent, or 19.13 points, to 1,950.90.

Hong Kong rose 0.16 per cent, or 38.16 points, to 23,215.16 and Shanghai added 0.57 per cent, or 13.87 points, to 2,432.40.

Japan's Nikkei suffered a sell-off for a second straight day on profit-taking - after surging 3.77 per cent to a four-and-half-year high on Wednesday - and a stronger yen, which had fallen to multi-month lows.

"The market is due for another pullback as it remains overheated and ripe for profit-taking, especially with the holiday-extended three-day weekend coming up," said SMBC Nikko Securities general manager of equities Hiroichi Nishi.

"The 'energy' in the market remains very strong, however," he told Dow Jones Newswires.

Data on Friday showed the surplus in Japan's current account, the broadest measure of Tokyo's dealings with the rest of the world, nearly halved to 4.7 trillion yen (US$50 billion) in 2012, the smallest since 1985.

The figures showed exports to China and Europe slumped, with December seeing a monthly deficit of 264.1 billion yen, from a year-earlier surplus of 265.7 billion yen.

Zhang Zhiwei, a Hong Kong-based economist with Nomura International, said in a research note: "These data suggest that external and domestic demand are both strong, which supports our view that the economy is on track for a cyclical recovery in the first half" of this year.

In afternoon forex trade, the dollar bought 92.37 yen, down from 93.61 yen in New York late Thursday, while the euro was at 123.80 yen, from 125.40 yen.

Europe's single currency also bought US$1.3401 from US$1.3395, having touched US$1.3711 last week.

Dealers moved to sell the euro after the European Central Bank held interest rates at record lows.

China's General Administration of Customs said the country's trade surplus rose in January, thanks to an improvement in exports and imports.

The surplus rose 7.7 per cent year-on-year to US$29.2 billion, beating a median US$26.6 billion forecast of economists in a Dow Jones Newswires survey.

Customs also said exports surged 25.0 per cent to US$187.4 billion, while imports climbed 28.8 per cent to US$158.2 billion.

Later in the day, the National Bureau of Statistics said inflation in January slowed to 2.0 per cent - in line with expectations - from a seven-month peak of 2.5 per cent in December.

On Wall Street, the Dow fell 0.30 per cent, the S&P 500 lost 0.18 per cent and the Nasdaq eased 0.11 per cent.

Oil prices rose, with New York's main contract, light sweet crude for delivery in March, increasing 17 cents to US$96.00 a barrel and Brent North Sea crude for March gaining 39 cents to US$117.63.

Gold was at US$1,670.25 at 1030 GMT compared with US$1,676.08 late Thursday.

In other markets, Manila was flat, slipping 1.32 points to close at 6,458.67; Wellington added 0.73 per cent, or 30.48 points, to 4,225.72; Jakarta shed 0.26 per cent, or 11.88 points, to 4,491.27; Kuala Lumpur gained 0.26 per cent, or 4.23 points, to 1,623.80; Bangkok lost 0.17 per cent, or 2.51 points, to 1,497.30; and Mumbai slipped 0.49 per cent, or 95.55 points, to 19,484.77.

Taipei was closed for a public holiday.

With the release of its raw compatibility update 4.04, Apple software now can handle raw-format photos from two hot new cameras, the Nikon D5200 SLR and the high-end compact Sony RX1.


The D5200 is a relatively inexpensive SLR whose 24-megapixel sensor looks to have promisingly high performance -- the top rating for an APS-C-sized sensor, according to DxO Labs' DxOMark test results. The $2,800 RX1 has an even larger full-frame sensor, also with a 24-megapixel resolution, but its design uses a fixed 35mm lens.




Also supported in the Apple update is support for raw photos from Pentax's K-5 II and K-5 IIs, which also get high marks from the DxO sensor test.


Apple has been turning the crank faster to keep up with the constant stream of new cameras, with eight raw support updates in the last year. Each update means that software such as iPhoto and Aperture that rely on OS X's raw-image support can handle newer cameras' formats. Raw photos, available on higher-end cameras, offer higher image quality and more flexibility than JPEGs, but they also require some manual processing that makes them less convenient than JPEGs.


Also supported in the update are Leica's D-Lux 6, V-Lux 4, and X2, and Pentax's Q and K-30.

Asteroid to Make Closest Flyby in History


Talk about too close for comfort. In a rare cosmic encounter, an asteroid will barnstorm Earth next week, missing our planet by a mere 17,200 miles (27,700 kilometers).

Designated 2012 DA14, the space rock is approximately 150 feet (45 meters) across, and astronomers are certain it will zip harmlessly past our planet on February 15—but not before making history. It will pass within the orbits of many communications satellites, making it the closest flyby on record. (Read about one of the largest asteroids to fly by Earth.)

"This is indeed a remarkably close approach for an asteroid this size," said Paul Chodas, a research scientist at NASA's Jet Propulsion Laboratory Near Earth Object (NEO) program office in Pasadena, California.

"We estimate that an asteroid of this size passes this close to the Earth only once every few decades."

The giant rock—half a football field wide—was first spotted by observers at the La Sagra Observatory in southern Spain a year ago, soon after it had just finished making a much more distant pass of the Earth at 2.6 million miles (4.3 million kilometers) away.

This time around however, on February15 at 2:24 pm EST, the asteroid will be passing uncomfortably close—ten times closer than the orbit of the moon—flying over the eastern Indian Ocean near Sumatra (map). (Watch: "Moon 101.")

Future Impact?

Chodas and his team have been keeping a close eye on the cosmic intruder, and orbital calculations of its trajectory show that there is no chance for impact.

But the researchers have not yet ruled out future chances of a collision. This is because asteroids of this size are too faint to be detected until they come quite close to the Earth, said Chodas.

"There is still a tiny chance that it might hit us on some future passage by the Earth; for example there is [a] 1-in-200,000 chance that it could hit us in the year 2080," he said.

"But even that tiny chance will probably go away within the week, as the asteroid's orbit gets tracked with greater and greater accuracy and we can eliminate that possibility."

Earth collision with an object of this size is expected to occur every 1,200 years on average, said Donald Yeomans, NEO program manager, at a NASA news conference this week.

DA14 has been getting closer and closer to Earth for quite a while—but this is the asteroid's closest approach in the past hundred years. And it probably won't get this close again for at least another century, added Yeomans.

While no Earth impact is possible next week, DA14 will pass 5,000 miles inside the ring of orbiting geosynchronous weather and communications satellites; so all eyes are watching the space rock's exact trajectory. (Learn about the history of satellites.)

"It's highly unlikely they will be threatened, but NASA is working with satellite providers, making them aware of the asteroid's pass," said Yeomans.

Packing a Punch

Experts say an impact from an object this size would have the explosive power of a few megatons of TNT, causing localized destruction—similar to what occurred in Siberia in 1908.

In what's known as the "Tunguska event," an asteroid is thought to have created an airburst explosion which flattened about 750 square miles (1,200 square kilometers) of a remote forested region in what is now northern Russia (map).

In comparison, an impact from an asteroid with a diameter of about half a mile (one kilometer) could temporarily change global climate and kill millions of people if it hit a populated area.

Timothy Spahr, director of the Minor Planet Center at Cambridge, Massachusetts, said that while small objects like DA14 could hit Earth once a millennia or so, the largest and most destructive impacts have already been catalogued.

"Objects of the size that caused the extinction of the dinosaurs have all been discovered," said Spahr. (Learn about what really happened to the dinosaurs.)

A survey of nearly 9,500 near-Earth objects half a mile (one kilometer) in diameter is nearly complete. Asteroid hunters expect to complete nearly half of a survey of asteroids several hundred feet in diameter in the coming years.

"With the existing assets we have, discovering asteroids rapidly and routinely, I continue to expect the world to be safe from impacts in the future," added Spahr.

Door-to-Door Search for Suspected Cop Killer













More than 100 police officers were going door-to-door and searching for new tracks in the snow in the hopes of catching suspected cop killer Christopher Dorner overnight in Big Bear Lake, Calif., before he strikes again as laid out in his chilling online manifesto.


Police held a news conference late Thursday, alerting the residents near Big Bear Lake that Dorner was still on the loose after finding his truck burning around 12:45 p.m. local time.


San Bernardino County Sheriff's spokeswoman Cindy Bachman said the authorities can't say for certain he's not in the area. More than half of the 400 homes in the area have been searched by police, who are traveling in two-man teams. Bachman urged people in the area to not answer the door, unless you know the person or law enforcement in uniform.


After discovering Dorner's burning truck near a Bear Mountain ski resort, police discovered tracks in the snow leading away from the vehicle. The truck has been taken to the San Bernardino County Sheriffs' crime lab.

Bachman would not comment on Dorner's motive for leaving the car or its contents, citing the ongoing investigation. Police are no aware of Dorner having any ties to others in the area.

She added that the search in the area would continue as long as the weather cooperates. About three choppers were being used overnight, but weather conditions were deteriorating, according to Bachman.


"He could be anywhere at this point," said San Bernardino County Sheriff John McMahon, who is expected to address the media later this morning.


Dorner, a former Los Angeles police officer and Navy reservist, is suspected of killing one police officer and injured two others Thursday morning in Riverside, Calif. He was also accused of killing two civilians on Sunday. And he allegedly released an angry "manifesto" airing grievances against police and warning of coming violence toward cops.


In the manifesto Dorner published online, he threatened at least 12 people by name, along with their families.
"Your lack of ethics and conspiring to wrong a just individual are over. Suppressing the truth will leave to deadly consequences for you and your family," Dorner wrote in his manifesto.


One passage from the manifesto read, "I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty."


"I never had the opportunity to have a family of my own," it read. "I'm terminating yours."


Hours after the extensive manhunt dragged police to Big Bear Lake, CNN's Anderson Cooper said Dorner had sent him a package at his New York office that arrived on Feb. 1, though Cooper said he never knew about the package until Thursday. It contained a DVD of court testimony, with a Post-It note signed by Dorner claiming, "I never lied! Here is my vindication."


PHOTOS: Former LAPD Officer Suspected in Shootings


It also contained a keepsake coin bearing the name of former Los Angeles Police Chief William J. Bratton that came wrapped in duct tape, Cooper said. The duct tape bore the note, "Thanks, but no thanks Will Bratton."


Bratton told Cooper on his program, "Anderson Cooper 360," that he believed he gave Dorner the coin as he was headed overseas for the Navy, Bratton's practice when officers got deployed abroad. Though a picture has surfaced of Bratton, in uniform, and Dorner, in fatigues, shaking hands, Bratton told Cooper he didn't recall Dorner or the meeting.

Three-legged robot uses exploding body to jump



Sandrine Ceurstemont, editor, New Scientist TV






Pumping air through a rubbery robot allows it to walk, but now you can make one jump by setting off explosions inside its body.







George Whitesides from Harvard University and colleagues have created a three-legged robot lined with tubes filled with a mixture of methane and oxygen. When an electrical spark ignites the gases, the combustion reaction generates bursts of pressure that propel the robot aloft (see video above). "By actuating all three legs simultaneously, we caused the robot to jump more than 30 times its height," write the team. As the height of the jump was limited by the size of the experimental chamber, they think it could spring twice as high without the attached tubing.



Using explosions allows the robot to move much more rapidly than it could with locomotion driven by compressed air. The experiments show that its silicone body can withstand the forces and temperatures generated by the burning gas.



Jumping robots are being investigated for search-and-rescue missions because they can leap over obstacles. A hard-bodied jumping flea robot was unveiled last year, but the low cost of soft-bodied robots could make them a disposable alternative. The team now plans to develop a way to steer the robot while also improving its jumping height and energy efficiency.

Nepal Maoists propose chief justice as new PM






KATHMANDU: Nepal's ruling Maoists on Thursday proposed that the chief justice be appointed prime minister and preside over parliamentary elections, calling it the only option to resolve a long-running political crisis.

The proposal was made by party chairman Pushpa Kamal Dahal, known by his nom de guerre Prachanda, at the Maoists' largest meeting since they toppled the monarchy in 2006 after a decade-long civil war and then took power in elections.

"In the meeting, chairman Prachanda proposed forming a government led by the chief justice of the supreme court," party spokesman Agni Sapkota told reporters.

"The proposed administration will hold the elections for Constituent Assembly. His proposal was approved by the delegates."

In-fighting, including a split in the party last year, has confounded efforts to draw up a post-war constitution spelling out how Nepal should be run as a modern, democratic republic.

An interim assembly elected for the task was dissolved in May last year and elections promised for November were shelved amid quarrelling among the main parties over who should lead a national unity government into the vote.

The Maoists now lead Nepal as the major partner in a fragile caretaker coalition that is carrying out the most essential tasks of government but has no popular mandate to make fundamental policy decisions.

Inaugurating the convention on Saturday, Dahal had said the Maoists would step down from the government and offered to give up leadership to an independent prime minister.

"We know that the constitution doesn't have a provision whereby a chief judge can lead such a government. But we are sure that the opposition parties will agree on this," Sapkota said.

"If this doesn't work, there's no other option. This is the last option. The opposition parties should come up with a better alternative. If there's none, we will launch a nationwide movement to sensitise people about the issue.

The introduction of a republican constitution and elections were key conditions of a deal that ended the civil war in which more than 16,000 died.

But the transition to democracy has been beset by the ethnic, caste, religious and ideological differences that have made agreement among the country's powerbrokers impossible.

While the Maoists want the creation of up to 14 states named after ethnic groups, their rivals say the plan would fuel unrest.

The convention in the southern industrial town of Hetauda is due to wrap up on Thursday night having gone a day over schedule.

Alcatel-Lucent CEO Ben Verwaayen stepping down

Alcatel-Lucent announced today that Ben Verwaayen is resigning after serving four years as the Franco-American network equipment maker.


The imminent resignation of Verwaayen, who will stay on while the company's board searches for a replacement, was previously reported by the Wall Street Journal.


"Alcatel-Lucent has been an enormous part of my life," Verwaayen said in a company statement. "It was therefore a difficult decision to not seek a further term, but it was clear to me that now is an appropriate moment for the Board to seek fresh leadership to take the company forward."


Verwaayen, the former head of BT Group PLC, was tapped in September 2008 to be chief executive in a bid to turn around the fortunes of the company, which had lost more than half its value since the former rivals started operating as a single entity in December 2006.


The Paris-based telecommunications equipment maker soon embarked on a significant restructuring as it tried to position itself to dominate telecom infrastructure in a post-recession world. But the past six years have been tough on the networking-equipment sector, particularly for the combined company, which has struggled to compete with the likes of Sweden's Ericsson and Chinese manufacturers such as Huawei.


When the company reveals its 2012 financial results later today, analysts expect a decline in quarterly operating income of more than $1 billion -- its seventh consecutive year of negative cash flow, according to the Journal.

Humans Swap DNA More Readily Than They Swap Stories

Jane J. Lee


Once upon a time, someone in 14th-century Europe told a tale of two girls—a kind one who was rewarded for her manners and willingness to work hard, and an unkind girl who was punished for her greed and selfishness.

This version was part of a long line of variations that eventually spread throughout Europe, finding their way into the Brothers Grimm fairytales as Frau Holle, and even into Shakespeare's The Merchant of Venice. (Watch a video of the Frau Holle fairytale.)

In a new study, evolutionary psychologist Quentin Atkinson is using the popular tale of the kind and unkind girls to study how human culture differs within and between groups, and how easily the story moved from one group to another.

Atkinson, of the University of Auckland in New Zealand, and his co-authors employed tools normally used to study genetic variation within a species, such as people, to look at variations in this folktale throughout Europe.

The researchers found that there were significant differences in the folktale between ethnolinguistic groups—or groups bound together by language and ethnicity. From this, the scientists concluded that it's much harder for cultural information to move between groups than it is for genes.

The study, published February 5 in Proceedings of the Royal Society B, found that about 9 percent of the variation in the tale of the two girls occurred between ethnolinguistic groups. Previous studies looking at the genetic diversity across groups in Europe found levels of variation less than one percent.

For example, there's a part of the story in which the girls meet a witch who asks them to perform some chores. In different renditions of the tale, the meeting took place by a river, at the bottom of a well, or in a cave. Other versions had the girls meeting with three old men or the Virgin Mary, said Atkinson.

Conformity

Researchers have viewed human culture through the lens of genetics for decades, said Atkinson. "It's a fair comparison in the sense that it's just variation across human groups."

But unlike genes, which move into a population relatively easily and can propagate randomly, it's harder for new ideas to take hold in a group, he said. Even if a tale can bridge the "ethnolinguistic boundary," there are still forces that might work against a new cultural variation that wouldn't necessarily affect genes.

"Humans don't copy the ideas they hear randomly," Atkinson said. "We don't just choose ... the first story we hear and pass it on.

"We show what's called a conformist bias—we'll tend to aggregate across what we think everyone else in the population is doing," he explained. If someone comes along and tells a story a little differently, most likely, people will ignore those differences and tell the story like everyone else is telling it.

"That makes it more difficult for new ideas to come in," Atkinson said.

Cultural Boundaries

Atkinson and his colleagues found that if two versions of the folktale were found only six miles (ten kilometers) away from each other but came from different ethnolinguistic groups, such as the French and the Germans, then those versions were as different from each other as two versions taken from within the same group—say just the Germans—located 62 miles (100 kilometers) away from each other.

"To me, the take-home message is that cultural groups strongly constrain the flow of information, and this enables them to develop highly local cultural traditions and norms," said Mark Pagel, of the University of Reading in the U.K., who wasn't involved in the new study.

Pagel, who studies the evolution of human behavior, said by email that he views cultural groups almost like biological species. But these groups, which he calls "cultural survival vehicles," are more powerful in some ways than our genes.

That's because when immigrants from a particular cultural group move into a new one, they bring genetic diversity that, if the immigrants have children, get mixed around, changing the new population's gene pool. But the new population's culture doesn't necessarily change.

Atkinson plans to keep using the tools of the population-genetics trade to see if the patterns he found in the variations of the kind and unkind girls hold true for other folktale variants in Europe and around the world.

Humans do a lot of interesting things, Atkinson said. "[And] the most interesting things aren't coded in our DNA."

Armstrong May Testify Under Oath on Doping













Facing a federal criminal investigation and a deadline that originally was tonight to tell all under oath to anti-doping authorities or lose his last chance at reducing his lifetime sporting ban, Lance Armstrong now may cooperate.


His apparent 11th-hour about-face, according to the U.S. Anti Doping Agency (USADA), suggests he might testify under oath and give full details to USADA of how he cheated for so long.


"We have been in communication with Mr. Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," USADA CEO Travis T. Tygart said in a written statement this evening. "We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."


Neither Armstrong nor his attorney responded to emails seeking comment on the USADA announcement.


The news of Armstrong's possible and unexpected cooperation came a day after ABC News reported he was in the crosshairs of federal criminal investigators. According to a high-level source, "agents are actively investigating Armstrong for obstruction, witness tampering and intimidation" for allegedly threatening people who dared tell the truth about his cheating.

The case was re-ignited by Armstrong's confession last month to Oprah Winfrey that he doped his way to all seven of his Tour de France titles, telling Winfrey he used performance-enhancing drugs throughout his career and then lied about it. He made the confession after years of vehement denials that he cheated.

WATCH: Armstrong's Many Denials Caught on Tape


If charges are ultimately filed, the consequences of "serious potential crimes" could be severe, ABC News legal analyst Dan Abrams said -- including "possible sentences up to five, 10 years."


Investigators are not concerned with the drug use, but Armstrong's behavior in trying to maintain his secret by allegedly threatening and interfering with potential witnesses.


Armstrong was previously under a separate federal investigation that reportedly looked at drug distribution, conspiracy and fraud allegations -- but that case was dropped without explanation a year ago. Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.


"There were plenty of people, even within federal law enforcement, who felt like he was getting preferential treatment," said T.J. Quinn, an investigative reporter with ESPN.


The pressures against Armstrong today are immense and include civil claims that could cost him tens of millions of dollars.


Armstrong is currently serving a lifetime ban in sport handed down by the U.S. Anti-Doping Agency, and today was the deadline he was given to cooperate under oath if he ever wanted the ban lifted.

Multi-ministerial taskforce set up to tackle dengue






SINGAPORE: A multi-ministerial taskforce has been set up to tackle the dengue scourge in Singapore.

The National Environment Agency said it comprises representatives from the Ministry of National Development, Ministry of Education, Ministry of Home Affairs and Ministry of Defence.

The taskforce will be activated to investigate any outbreak of dengue cases which has seen a spike recently.

The Health Ministry reported six cases of the more serious dengue haemorrhagic fever this year.

For the first time, dengue cases will also be reported more specifically at the street level.

Previously, it was done based on cluster location only.

Ng Say Kiat, president of Singapore Pest Management Association, said: "I think this is a very good initiative in the sense that you will let people be alert to prevent mosquito breeding at home. And if you noticed there are cases around your neighbourhood, you will definitely be more alert."

Twitter gives Vine an NC-17 rating after porn controversy



Vine update asks for ID -- kind of.



(Credit:
Steven Musil/CNET)



After a dustup over pornography showing up on Vine, the Twitter-owned video-sharing app has added an age rating for possible adult content.


The app for iPhone and
iPod Touch, which lets anyone create and share six-second clips, quickly became a popular venue for pornography after its release last month. Twitter responded by trying to make it harder for users to find the adult videos, blocking a number of porn-related search terms such as "#porn."


The microblogging site initially added a warning still to the beginning of videos in question that users would have to bypass to see the clip. As first noted by The Verge, Twitter released a new version today that requires users to confirm that they are at least 17 years of age; the previous version described itself for users 12 and older.




The app captured the controversy spotlight when a pornographic video briefly made Vine's "Editor Pick" list, further raising the question of whether the video-clip-sharing app has a porn problem.


However, the pop-up confirmation screen on version 1.0.5 appears to do little more to prevent access to questionable content than previous moves; children under the age of 17 lacking direct adult supervision can easily subvert this new obstacle to install the app.


CNET has contacted Twitter for comment on the new move and will update this report when we learn more.


The update follows similar moves by Tumblr and 500px, the latter of which was briefly removed from the Apple App Store presumably because of its photo-sharing capabilities, which might allow users to search for and find naked bodies.

The Real Richard III


It's a question that actors from Laurence Olivier to Kevin Spacey have grappled with: What did Richard III, the villainous protagonist of Shakespeare's famous historical drama, really look and sound like?

In the wake of this week's announcement by the University of Leicester that archaeologists have discovered the 15th-century British king's lost skeleton beneath a parking lot, news continues to unfold that helps flesh out the real Richard III.

The Richard III Society unveiled a 3D reconstruction today of the late king's head and shoulders, based on computer analysis of his skull combined with an artist's interpretation of details from historical portraits. (Related: "Shakespeare's Coined Words Now Common Currency.")

"We received the skull data before DNA analysis confirmed that the remains were Richard III, and we treated it like a forensic case," said Caroline Wilkinson, the University of Dundee facial anthropologist who led the reconstruction project. "We were very pleasantly surprised by the results."

Though Shakespeare describes the king as an "elvish-marked, abortive, rooting hog," the reconstructed Richard has a pleasant, almost feminine face, with youthful skin and thoughtful eyes. His right shoulder is slightly higher than the left, a consequence of scoliosis, but the difference is barely visible, said Wilkinson.

"I think the whole Shakespearean view of him as being sort of monster-like was based more on his personality than his physical features," she reflected.

Look back at 125 years of National Geographic history

People are naturally fascinated by faces, especially of historical figures, said Wilkinson, who has also worked on reconstructions of J.S. Bach, the real Saint Nicholas, the poet Robert Burns, and Cleopatra's sister.

"We make judgments about people all the time from looking at their appearance," she said. "In Richard's case, up to now his image has been quite negative. This offers a new context for considering him from the point of view of his anatomical structure rather than his actions. He had quite an interesting face."

A Voice From the Past

Most people's impression of Richard's personality comes from Shakespeare's play, in which the maligned ruler utters such memorable lines as "Now is the winter of our discontent/Made glorious summer by this son of York," and "A horse! A horse! My kingdom for a horse!"

But how would the real Richard III have expressed himself? Did he have an accent? Was there any sense of personality or passion in his choice of words?

To find out more about the mysterious monarch, Philip Shaw, a historical linguist at University of Leicester's School of English, analyzed the only two known examples of Richard III's own writing. Both are postscripts on letters otherwise composed by secretaries—one in 1469, before Richard became king, and one from 1483, the first year of his brief reign.

Shaw identified a quirk of spelling that suggests that Richard may have spent time in the West Midlands, or perhaps had a tutor who hailed from there.

"I was looking to compare the way he spells things with the way his secretaries spell things, working on the assumption that he would have been schooled to a fairly high level," Shaw explained.

Read about National Geographic explorers on our Explorers Journal blog

In the 1469 letter, Richard spells the word "will" as "wule," a variation associated with the West Midlands. But Shaw also notes that by 1483, when Richard wrote the second letter's postscript, he had changed his spelling to the more standard "wyll" (the letters 'i' and 'y' were largely interchangeable during that period of Middle English).

"That could suggest something about him brushing up over the years, or moving toward what would have been the educated standard," Shaw said, noting that the handwriting in the second example also appears a bit more polished. "One wonders what sort of practice and teaching he'd had in the interim."

Although it's hard to infer tone of voice from written letters, there is certainly emotion in the words penned by Richard III.

In the 1469 letter, the 17-year-old seeks a loan of 100 pounds from the king's undertreasurer. Although the request is clearly stated in the body of the letter, Richard adds an urgent P.S.: "I pray you that you fail me not now at this time in my great need, as you will that I show you my good lordship in that matter that you labour to me for."

That could either be a veiled threat (If you don't lend me the money, I won't do that thing you asked me to do) or friendly cajoling (Come on, I'm helping you out with something, so help me out with this loan).

"His decision to take the pen himself shows you how important that personal touch must have been in getting people to do something," Shaw said.

The second letter, written to King Richard's chancellor in 1483, also conveys a sense of urgency. He had just learned that the Duke of Buckingham—once a close ally—was leading a rebellion against him.

"He's asking for his Great Seal to be sent to him so that he can use it to give out orders to suppress the rebellion," Shaw said. "He calls the Duke 'the most untrue creature living. You get a sense of how personally let down and betrayed he feels."

Shaw said he hopes his analysis—in combination with the new facial reconstruction—will help humanize Richard III.

"He probably wasn't quite the villain that Shakespeare portrays, though I suspect he was quite ruthless," he said. "But you probably couldn't afford to be a very nice man if you wanted to survive as a king in those days."

Lance Armstrong Under Criminal Investigation













Federal investigators are in the midst of an active criminal investigation of disgraced former Tour de France champion Lance Armstrong, ABC News has learned.


The revelation comes in stark contrast to statements made by the U.S. Attorney for Southern California, Andre Birotte, who addressed his own criminal inquiry of Armstrong for the first time publicly on Tuesday. Birotte's office spent nearly two years investigating Armstrong for crimes reportedly including drug distribution, fraud and conspiracy -- only to suddenly drop the case on the Friday before the Super Bowl last year.


Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.


Today, a high level source told ABC News, "Birotte does not speak for the federal government as a whole."


According to the source, who agreed to speak on the condition that his name and position were not used because of the sensitivity of the matter, "Agents are actively investigating Armstrong for obstruction, witness tampering and intimidation."


An email to an attorney for Armstrong was not immediately returned.

Earlier Tuesday, during a Department of Justice news conference on another matter, Birotte was confronted with the Armstrong question unexpectedly. The following is a transcript of that exchange:


Q: Mr. Birotte, given the confession of Lance Armstrong to all the things --


Birotte: (Off mic.)


Q: -- to all thethings that you, in the end, decided you couldn't bring a case about, can you give us your thoughts on that case now and whether you might take another look at it?


Birotte: We made a decision on that case, I believe, a little over a year ago. Obviously we've been well-aware of the statements that have been made by Mr. Armstrong and other media reports. That has not changed my view at this time. Obviously, we'll consider, we'll continue to look at the situation, but that hasn't changed our view as I stand here today.


The source said that Birotte is not in the loop on the current criminal inquiry, which is being run out of another office.


Armstrong confessed to lying and using performance-enhancing drugs throughout his career in an interview with Oprah Winfrey.

Challenge unscientific thinking, whatever its source






















Science may lean to the left, but that’s no reason to give progressives who reject it a “free pass”
















IF SCIENCE could vote, who would it vote for? Ask scientists, and a clear answer comes back: science leans to the left.












A 2009 survey conducted by Pew Research in the US found that 52 per cent of scientists identified themselves as liberal, and slightly more believed the scientific community as a whole leaned that way. The corresponding figures for conservatism? Just 9 per cent and 2 per cent respectively.











This association between science and left-leaning politics can only have been reinforced by the disdain with which vocal right-wing politicians, particularly in the US, have treated scientific evidence in recent years. That contrasts with the Obama administration's endorsement of it - although words always come more readily than actions (see "How Obama will deliver his climate promise").












Certainly, some conservatives conspicuously reject those parts of science that clash with their world views - notably evolution, climate change and stem cell research. But this doesn't mean those on the left are automatically and unimpeachably pro-science. In "Lefty nonsense: When progressives wage war on reason", Alex Berezow and Hank Campbell put forward their view that unscientific causes and concerns are just as rife among progressives as conservatives. Conservatives may sometimes be blinkered by their enthusiasm for what they see as moral rectitude, but progressives can be overcome by "back to nature" sentiments on, say, food or the environment.













Berezow and Campbell further claim that progressives who endorse unscientific ideas get a "free pass" from the scientific community. The suspicion must be that this is because scientists themselves lean towards the left, as does the media that covers them. (Both friends and critics of New Scientist tell us we lean in that direction.)












Is there any substance to that suspicion? We should go to every possible length to ensure there isn't. Unreason of any hue is dangerous; any suggestion of bias only makes it harder to overcome. Science and liberalism are natural allies, but only in the literal sense of liberalism as the pursuit of freedom. That means freedom of thought, freedom of speech and, above all, freedom from ideology - wherever on the political spectrum it comes from.
