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.

Obama's Defense Nominee Chuck Hagel Stirs Washington Lawmakers Watch Video





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."

Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaƛ and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

Japan says China ships off disputed isles






TOKYO: Four Chinese government ships entered territorial waters around Japan-controlled islands at the centre of a dispute Monday, the Japanese coastguard said.

The four marine surveillance ships were seen moving within 12 nautical miles of the islands, known as the Senkakus in Japan and the Diaoyus in China, just before midday, the coastguard said in a statement.

It was the first time since December 31 -- and the 21st time since Japan nationalised the islands in September -- that any state-owned Chinese ship has been seen in the archipelago's waters, which lie in the East China Sea.

A state-owned Chinese plane flew through airspace over the islands early last month. Tokyo responded by scrambling fighter jets and said it was the first time Beijing had breached its airspace since at least 1958.

On Saturday, another Chinese state-owned plane approached the islands without entering the airspace, prompting another Japanese fighter jet dispatch.

Nvidia launches Shield, new gaming device at CES



Nvidia Shield

Nvidia CEO Jen-Hsun Huang unveils Nvidia Shield, a brand-new gaming device that leverages Android and the Tegra 4 quad-core processor.

James Martin/CNET)


LAS VEGAS--Who says you can't teach an old chipmaker new tricks? Not Nvidia. At CES, the company announced its own gaming device, Shield, which will bear its brand name as well as its quad-core Tegra 4 processor.



Shield looks like a portable
Xbox controller with a screen. It's got analog joysticks, buttons, and controllers. Shield promises between 5 and 10 hours of gameplay.


"It's pure
Android," says Nvidia CEO Jen-Hsun Huang. There's nothing proprietary about it; all jacks are standard and the platform is open. It comes with a microSD card slot.


Shield can connect to the cloud to play Tegra Zone games, and also supports multiplayer mode.


Big strides
The move from making chipsets to assembling the hardware that houses them is a bold one for Nvidia, which traditionally partners with device-makers to power their mobile and desktop computing hardware.


Becoming a hardware manufacturer in addition to creating processors would give Nvidia another revenue stream, as well as greater latitude in device designs that house their chips.

Though a surprising move, Nvidia does have some experience speccing out and creating devices. The company currently builds reference models that they then actively pitch to hardware partners, like Asus and Acer, for instance.


Most recently, Nvidia partnered with Leyden Energy to provide a longer-lasting battery for a
tablet reference design.

Nvidia isn't showing off its new tablet tonight, but CNET tablet reviewer Eric Franklin will get photos, video, and first impressions as soon as possible.

Pastor Accused of Killing Wives Faces Trial













Jury selection is scheduled to begin Monday for Pastor Arthur Schirmer, who is accused of killing his second wife and then staging a car accident to hide it.


Schirmer, 64, also faces a second trial at a later date for the death of his first wife. He has said he is innocent of all charges.


In 2008, the pastor and his wife, Betty, were involved in what appeared at the time to be a car crash. Schirmer told police at the time that he had been driving 55 mph and swerved to miss a deer, causing him to drive off the road, according to a police affidavit obtained by ABC News.


Schirmer also said at the time that his wife's head had come forward and struck the windshield, according to the affidavit. Betty died a day later and her body was cremated at the request of Schirmer.


It wasn't until a grisly suicide in 2010 inside Schirmer's office that authorities decided to revisit the case of Betty Schirmer's death and arrest the pastor.


The man who broke in and shot himself at the desk in Schirmer's office at the Reeders United Methodist Church, Joseph Mustante, was the husband of the pastor's secretary, Cynthia Mustante, Poconos Township Police Detective James Wagner said.






Pocono Record, David Kidwell/AP Photo











Mustante's suicide was prompted by the discovery that his wife and the pastor had apparently been having an affair, Wagner said. He was alone at the time of his death.


Investigators looking into the suicide say that several church parishioners had concerns about the deaths of Schirmer's two wives.


"That suicide eventually exposed the affair publicly and subsequent to that, questions arose about the loss of [Schirmer's] wives and his character became questionable," Wagner said.


Relaunching the investigation into the two deaths, Wagner said he quickly suspected that "foul play existed, and the car crash was staged," allegedly, by Schirmer. Wagner said investigators also believed there was something "suspicious" about the first wife's death, a marriage that investigators had not known about prior to the suicide.

Investigators Look Into Deaths of Rev. Arthur Schirmer's Wives



Schirmer's first wife, Jewel, died in April 1999 from a traumatic brain injury after she purportedly fell down a flight of stairs in Lebanon, Pa., Wagner said.


Lebanon is about 100 miles southwest of Reeders, where Schrimer later moved with his second wife.


At the time of Jewel's death, Wagner said, a relative told police that he suspected Schirmer may have had a hand in his wife's death but that the investigation was "never completed."


On Dec. 11, 2012 -- more than 13 years after Jewel died, a Lebanon County judge ruled Schirmer would be tried for her murder.


When investigators looked at the death of Betty Schirmer, they saw inconsistencies, Wagner said.


"There was no airbag deployment and it simply looked like a car that had driven off the road at a very low speed," Wagner said. "It didn't match the injuries to [Betty's head].


"I know there are people out there who probably know him and feel like there is absolutely no way he would be capable of doing this," Wagner of Schirmer. "But they clearly don't know him."
