Pruney fingers give us better grip underwater

WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.

Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.

To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.

With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.

So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Malaysian manhunt on as escape drama spices up

KUALA LUMPUR: Seven Malaysians who escaped police custody this week did so by temporarily blinding a guard with chilli powder hidden in one of the escapee's underpants, police and press reports said Wednesday.

The escape Monday of the seven men -- whom police have called "dangerous criminals" -- has prompted a large-scale manhunt in the northern Malaysian state of Penang.

But the seven escapees remained at large after their daring break-out from a police van as they were being transported to a local court.

The detainees had staged a fight in the vehicle, prompting its driver to pull over, police said.

When the police opened the rear door to investigate, "they threw chilli powder on a policeman", Abdul Rahman Ibrahim, a local police official, told AFP, as other detainees attacked and injured his fellow guards.

Abdul Rahman declined to elaborate on the use of the spices, but press reports have said one of the men had concealed the chilli powder in his underwear.

Chilli powder is ubiquitous in Malaysia, which is known for its spicy cuisine.

The seven fugitives then sped off in the police van, which was later found abandoned in a nearby village, police have said.

Some 250 police officers aided by tracker dogs and a police helicopter were scouring the area near where the van was discarded, said Abdul Rahim Hanafi, Penang's state police chief.

"The escapees are dangerous criminals who have been charged with serious offences, including murder, gang robbery and causing grievous hurt," he was quoted as saying by The Star newspaper.

Police were investigating how the detainees had obtained the chilli powder.

The Star quoted an unnamed source saying the powder could have been from the spicy seasoning sachets found in instant noodle packets that are sometimes provided to detainees by family members during visits.

LAS VEGAS--Lenovo's big-screen K900 smartphone is one of the first to integrate Intel's first dual-core Atom chip for phones.

By smartphone standards, the K900 has a massive 5.5-inch screen 1080p IPS display. So, no better time to tap Intel's new chip to manhandle all the pixels in that giant display.

The Atom Z2580 has roughly double the performance of Intel's single-core Medfield processor used in Lenovo's K800 phone. Some of that extra oomph comes from the extra processor core, some from the improved graphics chip.

A few more deets on Intel's Z2580: it's a 32-nanometer chip, so it does not use the 22-nanometer 3D chip tech seen in Intel's Ivy Bridge PC processors. That 22-nanometer phone chip will come later this year, Intel's Erik Reid told CNET today.

In addition to the spanking new Intel chip, other K900 goodies include 2GB of RAM, up to 16GB of NAND flash storage, a 2MP front-facing camera with a wide viewing angle, and a 13-megapixel F1.8 lens camera with dual flash.

And that camera alone may make it a contender. The K900's camera takes 13-megapixel pictures using a Sony CMOS Exmor BSI sensor. That could yield image quality on par with stand-alone digital camera.

Pictures: Wildfires Scorch Australia Amid Record Heat

Photograph by Jo Giuliani, European Pressphoto Agency

Smoke from a wildfire mushrooms over a beach in Forcett, Tasmania, on January 4. (See more wildfire pictures.)

Wildfires have engulfed southeastern Australia, including the island state of Tasmania, in recent days, fueled by dry conditions and temperatures as high as 113ºF (45ºC), the Associated Press reported. (Read "Australia's Dry Run" inNational Geographic magazine.)

No deaths have been reported, though a hundred people are unaccounted for in the town of Dunalley, where the blazes destroyed 90 homes.

"You don't get conditions worse than this," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons told the AP.

"We are at the catastrophic level, and clearly in those areas leaving early is your safest option."

Holmes Played Childish Games After Aurora Carnage

As police confronted the movie theater carnage and a massive booby trap left behind by accused Aurora gunman James Holmes, the suspect loopily played with hand puppets, tried to stick a metal staple in an electrical socket and clamly flipped a styrofoam cup, according to court testimony today.

Holmes, 25, displayed the bizarre behavior once he was in custody and taken to Aurora police headquarters after the shooting that left 12 people dead and dozens injured, the lead investigator in the case testified today.

While being cross examined by Colorado public defender Daniel King, Police Detective Craig Appel was asked about the observations of two Aurora officers assigned to watch over Holmes in an interrogation room.

Appel said that to preserve possible gunshot residue, police had placed paper bags over Holmes' hands. One officer, King said, noted in a report that Holmes began moving his hands "in a talking puppet motion."

King asked if Appel was also aware that the officer "observed Holmes take a staple out of the table and tried to stick it in an electrical socket?" Appel confirmed Holmes' actions.

The officers also noted that they watched as Holmes began playing with an empty styrofoam cup, trying to "flip it" on the table.

While Holmes was carrying out his childish antics, police were puzzling over a complex booby trap Holmes had left behind in his apartment, according to testimony.

A gasoline-soaked carpet, loud music and a remote control car were part of Holmes' plan to trick someone into triggering a blast that would destroy his apartment and lure police to the explosion while he shot up a movie theater in Aurora, Colo., according to court testimony.

FBI agent Garrett Gumbinner told the court that he interviewed Holmes on July 20, hours after he killed 12 and wounded 58 during the midnight showing of "The Dark Knight Rises."

"He said he rigged the apartment to explode to get law enforcement to send resources to his apartment instead of the theater," Gumbinner said.

His plan failed to prompt someone into triggering the bombs.

Gumbinner said Holmes had created two traps that would have set off the blast.

The apartment was rigged with a tripwire at the front door connected to a mixture of chemicals that would create heat, sparks and flame. Holmes had soaked the carpet with a gasoline mixture that was designed to be ignited by the tripwire, Gumbinner said.

"It would have caused fire and sparks," the agent said, and "would have made the entire apartment explode or catch fire."

Holmes had set his computer to play 25 minutes of silence followed by loud music that he hoped would cause a disturbance loud enough that someone would call police, who would then respond and set off the explosion by entering the apartment.

Gumbinner said Holmes also told him he rigged a fuse between three glass jars that would explode. He filled the jars with a deadly homemade chemical mixture that would burn so hot it could not be extinguished with water.

World's oldest pills treated sore eyes

In ancient Rome, physicians treated sore eyes with the same active ingredients as today. So suggests an analysis of pills found on the Relitto del Pozzino, a cargo ship wrecked off the Italian coast in around 140 BC.

"To our knowledge, these are the oldest medical tablets ever analysed," says Erika Ribechini of the University of Pisa in Italy, head of a team analysing the relics. She thinks the disc-shaped tablets, 4 centimetres across and a centimetre thick, were likely dipped in water and dabbed directly on the eyes.

The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite, echoing the widespread use of zinc-based minerals in today's eye and skin medications. Ribechini says there is evidence that Pliny the Elder, the Roman physician, prescribed zinc compounds for these uses almost 250 years after the shipwreck in his seminal medical encyclopaedia, Naturalis Historia.

The tablets were also rich in plant and animal oils. Pollen grains from an olive tree suggest that olive oil was a key ingredient, just like it is today in many medical and beauty creams, says Ribechini.

The tablets were discovered in a sealed tin cylinder called a pyxis (see image above). The tin must have been airtight to protect its contents from oxygen corrosion.

"Findings of such ancient medicines are extremely rare, so preservation of the Pozzino tablets is a very lucky case," says Ribechini.

The cargo of the wreck, discovered in 1989, is rich in other medical equipment, including vials and special vessels for bloodletting. This suggests that one of the passengers may have been a physician.

Private newspapers in Myanmar gearing up for the daily grind

YANGON: Private newspapers in Myanmar are gearing up to publish dailies for the first time, after authorities indicated they would begin issuing such licences in April.

Currently, only state-owned newspapers are allowed to publish dailies -- private ones are restricted to weeklies.

But observers caution that the still under-developed Myanmar economy might prove a challenge for private dailies.

There was a time when journalists from private newspapers like The Myanmar Times had to subject their reports to government censorship before the papers could be sent to the printers. But that changed last August, when authorities began reforming Myanmar's media regulations.

Geoffrey Goddard, senior editor of The Myanmar Times, said: "It was the curse of our professional lives and there was much celebration in the fourth estate when the decision was made by the government as part of the reform process to end pre-publication censorship."

Now, the government has indicated it will further liberalise the media sector -- by allowing applications for private daily licences as early as next month.

Mr Goddard added: "What we are eagerly looking forward to is the granting of licences to publish daily. That's the next big challenge for us and other newspapers in Myanmar."

The Myanmar Times has shown an interest in getting the license. But as with the rest of the world, the dailies have to contend with the onslaught of the online media. Currently, the Myanmar internet infrastructure might still be in the 90s, but it is expected to get up to speed soon.

There are more than 300 private weekly journals currently being published in Myanmar -- less than five are in English.

While many are excited at the prospect of publishing daily, observers doubt the viability of private dailies, given the country's under-developed economy.

Myo Aung, managing director of Success International Distributor, said: "Compared to neighbouring countries, our advertising budget is not very big. Most are local products. They advertise in magazines, journals and newspapers.

"But we hope that the government allows foreign investors to invest here. If foreign investors, and foreign firms and foreign expertise are here, I think our advertising scenario will also change very soon."

The government has already allowed foreign dailies to be distributed in the country.

And with the three state-controlled dailies currently having a circulation of 2.5 million copies a day, it will be a tough environment for upcoming private ones to compete in.

LAS VEGAS--Plantronics has long had Bluetooth-compatible headsets and speakers, but those with PCs have largely been left out of the party.

Until now. At CES this week, Plantronics is showing a wide array of its headphones and speakers, many of which focus exclusively on Bluetooth compatibility. But with the Voyager Legend UC and the Calisto 620, PC users wanting to listen to their favorite music on their mobile devices or wanting to make VOIP calls from their PCs can play along.

With its Voyager Legend UC headphones, Plantronics is now offering the ability to listen in on audio from mobile devices, and to make calls through services like Skype, Tango, or Vongage wirelessly, a step up from its previously-released Voyager Legend. While the headphones use Bluetooth to connect with mobile devices, it works along with a plug-in dongle that attaches to a computer's USB port, allowing for a Bluetooth connection, regardless of whether the PC has native Bluetooth.

Plantronics is also touting the functionality of the Voyager Legend UC's case -- an odd thing for a company not named Apple. But it makes sense given that the case has a built-in charger that lets users power up their headphones two additional times.

At the same time, Plantronics' Calisto 620 offers similar functionality -- for a wireless speaker. Users can connect it wirelessly to their mobile devices, or wirelessly via a similar plug-in dongle to a PC, allowing them to listen to VOIP calls on a speaker.

Primitive and Peculiar Mammal May Be Hiding Out in Australia

It’d be hard to think of a mammal that’s weirder than the long-beaked, egg-laying echidna. Or harder to find.

Scientists long thought the animal, which has a spine-covered body, a four-headed penis, and a single hole for reproducing, laying eggs, and excreting waste, lived only in New Guinea. The population of about 10,000 is critically endangered. Now there is tantalizing evidence that the echidna, thought to have gone extinct in Australia some 10,000 years ago, lived and reproduced there as recently as the early 1900s and may still be alive on Aussie soil.

The new echidna information comes from zoologist Kristofer Helgen, a National Geographic emerging explorer and curator of mammals at the Smithsonian Institution. Helgen has published a key finding in ZooKeys confirming that a skin and skull collected in 1901 by naturalist John T. Tunney in Australia is in fact the western long-beaked echidna, Zaglossus bruijnii. The specimen, found in the West Kimberley region of Western Australia, was misidentified for many years.

(More about echidnas: Get to know this living link between mammals and reptiles.)

Helgen has long been fascinated by echidnas. He has seen only three in the wild. “Long-beaked echidnas are hard to get your hands on, period,” he said. “They are shy and secretive by nature. You’re lucky if you can find one. And if you do, it will be by chance.” Indeed, chance played a role in his identification of the Australian specimen. In 2009, he visited the Natural History Museum of London, where he wanted to see all of the echidnas he could. He took a good look in the bottom drawer of the echidna cabinet, where the specimens with less identifying information are often stored. From among about a dozen specimens squeezed into the drawer, he grabbed the one at the very bottom.

(Related from National Geographic magazine: “Discovery in the Foja Mountains.”)

“As I pulled it out, I saw a tag that I had seen before,” Helgen said. “I was immediately excited about this label. As a zoologist working in museums you get used to certain tags: It’s a collector’s calling card. I instantly recognized John Tunney’s tag and his handwriting.”

John Tunney was a well-known naturalist in the early 20th century who went on collecting expeditions for museums. During an Australian expedition in 1901 for Lord L. Walter Rothschild’s private museum collection, he found the long-beaked echidna specimen. Though he reported the locality on his tag as “Mt Anderson (W Kimberley)” and marked it as “Rare,” Tunney left the species identification field blank. When he returned home, the specimen was sent to the museum in Perth for identification. It came back to Rothschild’s museum identified as a short-beaked echidna.

With the specimen’s long snout, large size, and three-clawed feet, Helgen knew that it must be a long-beaked echidna. The short-beaked echidna, still alive and thriving in Australia today, has five claws, a smaller beak, and is half the size of the long-beaked echidna, which can weigh up to 36 pounds (16 kilograms).

As Helgen began tracing the history and journey of the specimen over the last century, he crossed the path of another fascinating mind who had also encountered the specimen. Oldfield Thomas was arguably the most brilliant mammalogical taxonomist ever. He named approximately one out of every six mammals known today.

Thomas was working at the Natural History Museum in London when the Tunney echidna specimen arrived, still misidentified as a short-beaked echidna. Thomas realized the specimen was actually a long-beaked echidna and removed the skull and some of the leg bones from the skin to prove that it was an Australian record of a long-beaked echidna, something just as unexpected then as it is now.

No one knows why Thomas did not publish that information. And the echidna went back into the drawer until Helgen came along 80 years later.

As Helgen became convinced that Tunney’s long-beaked echidna specimen indeed came from Australia, he confided in fellow scientist Mark Eldridge of the Australian Museum about the possibility. Eldridge replied, “You’re not the first person who’s told me that there might be long-beaked echidnas in the Kimberley.” (That’s the Kimberley region of northern Australia.) Scientist James Kohen, a co-author on Helgen’s ZooKeys paper, had been conducting fieldwork in the area in 2001 and spoke to an Aboriginal woman who told him how “her grandmothers used to hunt” large echidnas.

This is “the first evidence of the survival into modern times of any long-beaked echidna in Australia,” said Tim Flannery, professor at Macquarie University in Sydney. “This is a truly significant finding that should spark a re-evaluation of echidna identifications from across northern Australia.”

Helgen has “a small optimism” about finding a long-beaked echidna in the wild in Australia and hopes to undertake an expedition and to interview Aboriginal communities, with their intimate knowledge of the Australian bush.

Though the chances may be small, Helgen says, finding one in the wild “would be the beautiful end to the story.”

Meet Obama's Defense Secretary Nominee

President Obama nominated former Senator Chuck Hagel as the next U.S. secretary of defense. To those who haven't followed the Senate closely in the past decade, he's probably not a household name.

Hagel is a former GOP senator from Nebraska and Purple-Heart-decorated Vietnam veteran, but he wouldn't necessarily be a popular pick with Republicans in Congress.

At age 21, Hagel and his brother Tom became the next in the family to serve in the United States Army. They joined the masses of Americans fighting an unfamiliar enemy in Vietnam.

In his book, he describes finding himself "pinned down by Viet Cong rifle fire, badly burned, with my wounded brother in my arms."

"Mr. President, I'm grateful for this opportunity to serve our country again," Hagel said after Obama announced his nomination Monday.

In 1971, Hagel took his first job in politics as chief of staff to Congressman John Y. McCollister, a position he held for six years. After that, he moved to Washington for the first time, where he went on to work for a tire company's government affairs office, the 1982 World's Fair and in 1981, as Ronald Reagan's Deputy Administrator of the Veterans Administration.

He worked in the private sector for most of the 80s and 90s before his first election to the Senate in 1997.
Since the turn of the century, Hagel has followed a curvy path of political alliances that puts his endorsements all over the map. Hagel's record of picking politically unpopular positions could be a large part of why Obama is naming him for the job, as Slate's Fred Kaplan surmises the next Defense secretary will be faced with tough choices.

In 2000, he was one of few Republican senators to back Sen. John McCain over then-presidential-candidate George W. Bush.

After that election, Hagel fiercely criticized Bush for adding 30,000 surge troops to Iraq, in place of the bipartisan Iraq Study Group's proposal of a draw-down and regional diplomacy, which Hagel preferred. When Bush instead announced that more troops would go to Iraq, Hagel co-sponsored a nonbinding resolution to oppose it, along with then-Sen. Joe Biden, D-Del.

"The president says, 'I don't care.' He's not accountable anymore," Hagel told Esquire in June 2007. "He's not accountable anymore, which isn't totally true. You can impeach him, and before this is over, you might see calls for his impeachment. I don't know. It depends how this goes."

Hagel's fierce opposition to America's involvement in Iraq – he called it one of the five monumental blunders of history, on par with the Trojan War – will be of substantial importance as the Obama administration charts our course out of Afghanistan, deciding how to withdraw the last of the troops in 2014 and how much of a presence to leave behind.

Hagel's support for McCain, which was substantial in his competition against Bush, disappeared in the 2008 election. Hagel toured Iraq and Afghanistan with Obama during his first campaign for the presidency.

In October 2008, Hagel's wife, Lillibet, announced her support for the Obama team, after the Washington Post reported on her donations to his campaign. She donated again in 2012.

Before the 2008 election, Hagel wrote: "The next president of the United States will face one of the most difficult national security decisions of modern times: what to do about an Iran that may be at the threshold of acquiring nuclear weapons."
