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.

AIM deal begs questions: Tan Cheng Bock

SINGAPORE: Former long-time PAP backbencher Tan Cheng Bock has weighed in on the controversy surrounding the sale of computer systems used by town councils, raising several questions in a post on his Facebook page on Monday, including whether it was right and beneficial to give up ownership of software developed using public funds.

Dr Tan, who was chairman of West Coast-Ayer Rajah Town Council from 2001 to 2004, also questioned whether the town councils, as "public institutions" - a description that was disputed by Tampines GRC MP Baey Yam Keng, who said they were "political organisations" - did the right thing selling the system to Action Information Management (AIM), "a company owned by a political party with its own agenda".

The sale of the systems to a company that is wholly-owned by the PAP "begs a few questions", said Dr Tan, "especially when the company may not serve, 'due to material change', an opposition ward".

"This software is developed using public funds by town councils. Is it right for the TCs to give up ownership in this manner?" he asked.

"So did the town councils as public institutions do the right thing, selling (the system) to a company owned by a political party with its own agenda?"

Dr Tan also questioned the need to introduce AIM as a "middle man" between the town councils and the software developers. He asked if this arrangement raised the town councils' costs, which will eventually be borne by constituents.

"As AIM is now the owner, is it going to pay the costs for any upgrade or new software development? How much is AIM then going to charge the town councils, which now is at the mercy of AIM?" he wrote.

"As town councils are public institutions, citizens are certainly uncomfortable with political party-owned companies transacting with the town councils.

"Much more clarity and transparency are needed."

In response to TODAY's queries, Dr Tan said he "had no problem" with the town councils harmonising the systems in 2003, but added that he was not around when a consultancy was engaged to review the systems -it later recommended that the systems be sold to a third party.

The episode was sparked by Workers' Party (WP) Chairman Sylvia Lim attributing Aljunied-Hougang Town Council's less-than-stellar performance in the Dec 14 Town Council Management Report to AIM's sudden termination of its contract.

It led to a war of words between WP and the PAP town councils.

But Mr Baey, who had to field several questions on the same issue during his regular Facebook chats on Sunday, felt the matter had been unnecessarily politicised.

Noting that town councils are run by political parties, Mr Baey, who is the vice-chairman of Tampines Town Council, added: "I feel that we may be reading too much into the political association. Because in the first place it's a political organisation."

Although town councils provide a public service, Mr Baey felt that "they're not public institutions; they're not a public service company".

"They do not belong to the government. They're governed by government regulations, but they're definitely not run by civil servants; and they're not a public agency," he told TODAY.

Questions on whether the tender process was properly done and if there was a conflict of interest regarding the sale were also directed at Mr Baey during his Facebook chat.

He responded that the focus should instead be on whether AIM had failed in its commitment to the town councils and whether its fees have been unreasonable.

FeltAudio debuts clip-on Bluetooth speaker and earbuds

The FeltAudio Rewind in white.

If you're always losing your Bluetooth headphones or speakers, FeltAudio's products could be for you. The FeltAudio Pulse is a tiny Bluetooth speaker that can be clipped on to a shirt pocket or belt, while the Rewind is a pair of in-ear headphones with a retractable cable.

The Pulse speaker works quite simply. You pair it with your handset and clip it on to some part of your clothing. When you're not using the speaker (or if you want the speaker playing back audio while attached to your phone), you can clip it to special Felt cases -- these are lined on the insides with actual felt -- which will be available for the
iPhone 5 as well as iPad. The company is working on versions for
iPad Mini and new
iPod Touch.

The Rewind headphones are a little more confusing. Since these are retractable Bluetooth headphones, we're guessing you'll need to clip the receiver portion (and case) to your shirt while listening to music. When you're done, the headphones retract into the portable case, which can then be attached to the back of a Felt case. There's also an inline mic on the cable for phone calls.

While we aren't sure if having a speaker or pair of headphones attached to the back of an phone case is a good idea for everyone, we're definitely impressed at the simplicity and elegance of the concept. The FeltAudio case, Pulse speaker, and Rewind headphones will all be available in white, gray, and black. No word yet on price and availability.

This is how the headphones would look stored on the back of a FeltAudio iPhone 5 case.

Billions of Earthlike Planets Found in Milky Way

Tens of billions of Earthlike worlds are strewn across the Milky Way, many of them circling stars very much like our own sun, astronomers said today.

Earlier research suggested that rocky planets might be much more abundant around small stars than sunlike ones. (Also see "New 'Super Earth' Found at Right Distance for Life.")

But a fresh analysis of data from NASA's Kepler mission, which launched in 2009, suggests this is not the case, according to new research presented at the annual meeting of the American Astronomical Society in Long Beach, California.

"We found that the occurrence of small planets around large stars was underestimated," said astronomer Francois Fressin, of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.

A Starry Night ... Full of Planets

To find planets, Kepler stares at a patch of sky in the constellation Cygnus, made up of about 150,000 stars. The space telescope detects potential alien worlds by watching for telltale dips in starlight created when planets pass in front of, or "transit," their parent stars.

Using their own independent software for analyzing Kepler's potential planet detections, Fressin and his colleagues estimate that about 17 percent, or one in six, of all the sunlike stars in the Milky Way host a rocky planet that orbits closer than the distance at which Mercury orbits our own sun.

Since the Milky Way is home to about a hundred billion stars, that means there are at least 17 billion rocky worlds out there. (See Milky Way pictures.)

When the team expanded their search to Earth-size orbits or larger, they found that half of all sunlike stars may host rocky planets.

"Every time you look up on a starry night, [nearly] each star you're looking at has a planetary system," Fressin said.

A Hundred Billion Planets?

Rocky planets are just a fraction of the total number of planets in our Milky Way, however.

A study of the number of potential worlds orbiting M-dwarfs—faint stars smaller than our sun that make up the vast majority of the stellar population—suggests our galaxy may be home to at least a hundred billion planets overall. (See "Four White Dwarfs Found Eating Earthlike Planets.")

"Based on our calculations, which are very complimentary to those of [Fressin] ... we are showing that there is about one planet per star, and that gives us a total of about a hundred billion planets throughout our galaxy," said Caltech planetary astronomer John Johnson.

"The vast majority of those planets are orbiting stars that are very much different from our sun."

Cops Break Down as They Describe Aurora Horror

Two veteran police officers broke down on the stand today during a preliminary hearing for accused movie theater gunman James Holmes, with one officer choking up when he described finding the body of a 6-year-old girl inside the theater.

Sgt. Gerald Jonsgaard needed a moment to compose himself as he described finding the little girl, Veronica Moser Sullivan, in the blood splattered theater in Aurora, Colo.

An officer felt for a pulse and thought Veronica was still alive, Jonsgaard said, but the officer then realized he was feeling his own pulse.

A preliminary hearing for Holmes began today in Colorado, with victims and families present. He is accused of killing 12 people and wounded dozens more in the movie theater massacre. One of Veronica's relatives likened attending the hearing to having to "face the devil."

The officers wiped away tears as they described the horror they found inside of theater nine.

Officer Justin Grizzle recounted seeing bodies lying motionless on the floor, surrounded by so much blood he nearly slipped and fell.

Grizzle, a former paramedic, says ambulances had not yet made it to the theater, so he began loading victims into his patrol car and driving to the hospital.

"I knew I needed to get them to the hospital now, " Grizzle said, tearing up. "I didn't want anyone else to die."

James Holmes Tries to Harm Himself, Sources Say Watch Video

Aurora, Colorado Gunman: Neuroscience PhD Student Watch Video

Grizzle drove six victims in four trips, saying that by the end there was so much blood in his patrol car he could hear it "sloshing around."

Click here for full coverage of the Aurora movie theater shooting.

An officer who took the stand earlier today described Holmes as "relaxed" and "detached" when police confronted him just moments after the shooting stopped.

The first two officers to testify today described responding to the theater and spotting Holmes standing by his car at the rear of the theater on July 20, 2012. He allegedly opened fire in the crowded theater during the midnight showing of "The Dark Knight Rises."

Officer Jason Oviatt said he first thought Holmes was a cop because he was wearing a gas mask and helmet, but as he got closer realized he was not an officer and held Holmes at gunpoint.

Throughout the search and arrest, Holes was extremely compliant, the officer said.

"He was very, very relaxed," Oviatt said. "These were not normal reactions to anything. He seemed very detached from it all."

Oviatt said Holmes had extremely dilated pupils and smelled badly when he was arrested.

Officer Aaron Blue testified that Holmes volunteered that he had four guns and that there were "improvised explosive devices" in his apartment and that they would go off if the police triggered them.

Holmes was dressed for the court hearing in a red jumpsuit and has brown hair and a full beard. He did not show any reaction when the officers pointed him out in the courtroom.

This is the most important court hearing in the case so far, essentially a mini-trial as prosecutors present witness testimony and evidence—some never before heard—to outline their case against the former neuroscience student.

The hearing at the Arapahoe County District Court in Centennial, Colo., could last all week. At the end, Judge William Sylvester will decide whether the case will go to trial.

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 Karaś 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.

Pure adds louder Jongo and hi-fi adapter to streaming range

The Pure Jongo T640B wants to be your main hi-fi.

Pure)

LAS VEGAS--Pure is a British company trying to crack the streaming-audio market with a set of cheap, colorful Wi-Fi and Bluetooth speakers that offer some of the functions of a Sonos. Today it's adding a higher-end speaker to the midrange model that it announced last year.

Called the Jongo T640B, Pure says it's designed to act as the main hi-fi in a living room. With 100 watts of power produced by two 5-inch drivers, it may well have a point. Stands are available from Pure so the Jongo can sit upright rather than lying down, or be mounted on the wall.

Jongo products are designed to be used with smartphones and
tablets. Download Pure's app and you can stream the music on your device to the speaker using Bluetooth or Wi-Fi.

If you have more than one Jongo, they can all be set up to play the same piece of music simultaneously, but you can't send different tracks to be played on two or more Jongos from the same phone or tablet. Pure says its app works with iPhones, iPads, and
iPod Touches running at least iOS 5 and
Android version 2.2.

The Pure Jongo A140B is an adapter for an existing hi-fi with Wi-Fi and Bluetooth.

The Jongo T640B will sell for $329 in the U.S. and £250 in the U.K., which makes it cheaper than Sonos' Play:5, but more expensive than the Play:3. Given the huge number of extra functions the Sonos products have, it's going to have to sound amazing to justify that price tag. It'll ship in the first half of the year.

Pure is also announcing a new hi-fi adapter today that adds the same streaming-audio functions to an existing hi-fi. Called the Jongo A140B, it has Wi-Fi and Bluetooth with analogue audio outputs plus optical and coaxial digital ports. Plug one of those into an old hi-fi you have knocking around, and you can use the Pure app to stream music in the same way as the other Jongo speakers.

It will sell for $119 in the U.S. and 99 pounds in the U.K. when it ships this year, which is slightly more than Apple's AirPort Express. Apple's product doesn't have Bluetooth, but even so that seems on the expensive side to me.

Hagel to Be Obama's Defense Secretary Nominee

Jan 6, 2013 4:52pm

WASHINGTON, D.C. — President Obama will nominate former senator Chuck Hagel to be his next Secretary of Defense tomorrow.

Senior officials within the administration and Capitol Hill confirmed the pick to ABC News today after the Nebraska Republican had emerged as a frontrunner among potential candidates several weeks ago.

Hagel, 66, is a decorated Vietnam veteran and businessman who served in the senate from 1997 to 2009. After having sat on that chamber’s Foreign Relations and Intelligence Committees,  he has in recent years gathered praise from current and former diplomats for his work on Obama’s Intelligence Advisory Board as well as the policy board of the current Defense Secretary Leon Panetta.

But the former lawmaker faces an upscale battle in the coming confirmation hearings in Congress; critics on both sides of the aisle have taken aim at his record toward Israel and what some have called a lack of experience necessary to lead the sprawling Pentagon bureaucracy or its operations.

Progressives have also expressed concern about comments he made in 1998, questioning whether an “openly, aggressively gay” James Hormel could be nominated to an ambassador position by then-President Clinton. Hagel apologized for the comments last month, adding that he also supported gays in the military – a position he once opposed.

Who Is Chuck Hagel? Meet Obama’s Top Pentagon Pick

The friction with his former colleagues has left a degree of uncertainty in the air going into the hearings. Today on ABC’s “This Week,” Senate Republican Leader Mitch McConnell demurred when asked whether he would support the man who, in 2008, he had championed for his candidness and stature in foreign policy.

“I’m going to wait and see how the hearings go and see whether Chuck’s views square with the job he would be nominated to do,” he told George Stephanopoulos.

Senator Lindsey Graham was more blunt in his opposition to Hagel on CNN. The Georgia Republican called Hagel an “in your face nomination,” and said he “would be the most antagonistic secretary of defense towards the state of Israel in our nation’s history.”

If confirmed, Hagel will join a crop of new cabinet members expected to join the president in his second term, including Sen. John Kerry, D-Mass., who was nominated in December to replace Hillary Clinton as Secretary of State.

ABC’s Elizabeth Hartfield and Devin Dwyer contributed reporting.
