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.

Football: Italy pledges action on football racists






MILAN: Italian interior minister Annamaria Cancellieri on Monday called for "more incisive" action to be taken to end the abuse of non-white players by racist fans.

Cancellieri was speaking after AC Milan's Kevin-Prince Boateng last week responded to racist chants by a small group of fans during a friendly against fourth division side Pro Patria by storming off the pitch.

He was followed by his team-mates, prompting a global outpouring of applause for the German-born Ghanaian international's stance against racist supporters.

Police have identified six Pro Patria supporters suspected of racist chanting and later Monday they were facing a five-year stadium ban.

One of the six suspects was identified by police thanks to television pictures as the Councillor for Sports and Youth Policy of the City of Corbetta near Milan, Riccardo Grittini.

All six were card-carrying fans of Pro Patria, one of whom worked in one of the club's bars.

According to ANSA news agency, all six have admitted being part of the crowd which verbally abused Milan's players but claim not to have uniquely targeted Milan's non-white players.

Sepp Blatter, the president of world football's governing body FIFA, hit out at Boateng's decision to force the suspension of last week's friendly, setting him at odds with AC Milan owner-president, Italy's former prime minister Silvio Berlusconi.

Both FIFA and UEFA have previously warned against players walking off the pitch in protest, and Blatter said: "Walk off? No. I don't think that is the solution."

Cancellieri said Boateng's stance was a "nice gesture" but told Radio 24 Monday that a "more comprehensive strategy" needed to be put in place to avoid games being decided by "a minority of racists".

"This episode drew attention to a phenomenon which is unfortunately widespread and, as such, we have to be more serious about dealing with it," Cancellieri said.

At Rome's Olympic Stadium on Saturday some sections of Lazio's crowd were heard making monkey noises at Cagliari's Colombian striker Victor Ibarbo. The majority of the home crowd jeered and whistled to drown out the racists.

The regulations regarding the suspension of matches in such circumstances remain unclear and is a potential minefield for the football authorities, who would either have to replay matches or award victory to the team being victimised.

Cancellieri suggested that if "only a small group of fans" were involved in racist chanting games "should not be suspended".

"Fans involved in racist chanting should be hit very hard and must be removed from the stadium," she said. "If, however, the phenomenon is more widespread the game must be suspended by whoever is responsible for keeping public order."

There have been suggestions that police officials, who already attend football games in Italy's Serie A, could play a bigger role in deciding whether football games are suspended or not due to racist chanting.

Cancellieri said a meeting would be held between Italy's chief of police and the president of Serie A later this week to discuss ways to eliminate abusive fans from matches without necessarily forcing stoppages.

Berlusconi, meanwhile, said he disagreed with Blatter's appraisal of Boateng's gesture after vowing last week that his players would do the same again in a similar situation and calling the scenes at Pro Patria "disgraceful".

"I am of the opposite opinion. I congratulated the players for their courage in standing up to this abhorrent incident," he told Tgcom24, which is part of his Mediaset group.

"Football reflects society and should be something positive; teams should shown an example to the rest of society. What happened in the stadium should not be dismissed, it has done a lot of damage including to the reputation of Italy."

The "Internet of Things" gets a consortium


Buzzword Central, also known as the Consumer Electronics Show, is getting a new entry.

In the never-ending quest to hook up the physical and digital worlds -- as we wait for the world of networked computing to spread beyond the boundaries of computers and smartphones to just about anything -- a new consortium will hold its first meeting this week at CES to compare notes. The so-called "Internet of Things Consortium" is a non-profit organization which says its mission is to spur "cooperation between hardware, software, and service providers, the ostensible goal being to pave the way for more intelligent home appliances, like talking refrigerators or smart ovens.

In its announcement, the group indicated that its initial efforts would focus on "those Internet enabled devices and related software services that directly touch consumers in the form of home automation, entertainment, and productivity. One of the goals of the consortium is to see billions of connected devices that benefit from communication with other devices and services."

Despite the recent attention in the news, the concept is not new. The idea's received increasing attention, especially since the advent of former Apple whiz Tony Fadell's startup Nest, which makes smart thermostats.

Wasp Larvae Practice Food Safety


From refrigeration and pasteurization to hand washing and health inspections, humans go to great lengths to prevent foodborne illnesses—and it turns out we're not alone. A new study reveals that the parasitic emerald cockroach wasp (Ampulex compressa) has developed its own food hygiene technique, cleansing its cockroach victim using a cocktail of antimicrobial liquids.

(Read a related article on food safety in National Geographic magazine.)

When reproducing, emerald cockroach wasp mothers attach one egg to the leg of an American cockroach (Periplaneta americana). Once the egg hatches, the larva bores a hole in the insect and moves inside. There, it feeds on the roach's internal organs before spinning a cocoon within the carcass and eventually emerging as an adult wasp. (Watch a related video on the parasitic black wasp.)

However, due to the cockroach's unsanitary living conditions, many bacteria, viruses, and fungi also make their home on the cockroach, infecting the young wasp's only food source and threatening its survival.

"It was clear that a species that feeds on these cockroaches had to protect its food and ... itself from foodborne illnesses," said Gudrun Herzner, an entomologist at the Institute of Zoology at the University of Regensburg in Germany and lead author on the study. "This [environment] was a good place to look for antimicrobial defense mechanisms." (Related: "Cockroach Brains May Hold New Antibiotics?")

A Potent Combination

Herzner and her team wanted to investigate just how these wasp larvae were protecting themselves from the microbes in their contaminated food source. So the team began collecting droplets of a liquid secreted by the larvae when inhabiting their hosts.

Analysis revealed that the two most prevalent chemicals in the secretion—mullein and micromolide—in combination were effective antimicrobial agents against bacteria commonly found on American cockroaches.

Though both compounds had been previously identified in other organisms, Herzner's study, published this week in the Proceedings of the National Academy of Sciences, was the first to find this specific combination of chemicals in the same source. "It seems that it's exactly this mixture [that gives] broad-spectrum protection from different kinds of bacteria," Herzner said.

This broad-spectrum strategy also prevents the development of bacterial resistance, similar to combination antibiotic therapy in humans. "[The wasps] virtually soak their cockroaches with these antimicrobial secretions, and in this way, they sanitize the cockroach," said Herzner.

An Ugly World

Parasitization, such as what the emerald cockroach wasp does to cockroaches, is very common in the insect world, said Jim Whitfield, professor of entomology at the University of Illinois, who was not involved with the study. "Almost every species of insect larva has some kind of parasite that attacks it ... It's a pretty ugly world out there if you're an insect larva," he said.

However, this wasp larva's specific method of defense is quite unique, Whitfield added.  "Normally the adult female wasp produces the compounds that protect the offspring, and not the larva itself. In this case, it sounds like it's the larva that produces it," he said.

The discovery of this antimicrobial combination could one day even be used in food safety techniques or antibiotic therapies for humans. In fact micromolide has been a promising lead compound against the microbe that causes tuberculosis, Herzner said.

She added that there could be other compounds, more potent and powerful than what the wasp larvae employ, out there right now. "Evolution might still be working to make an even better combination [for defense]," Herzner said. (Related: "Drug-Resistant Bacteria Found in 4-Million-Year-Old Cave.")

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."

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."

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 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.

Football: Milan call on football powers to act on racism






MILAN: AC Milan have called for football's authorities to take an official stand against racism in the sport as the controversy surrounding Kevin-Prince Boateng's walk-off continued on Sunday.

Boateng hit the headlines last week when he responded to racist chants by a small group of fans during a friendly against fourth division side Pro Patria by storming off the pitch.

He was followed by his team-mates, prompting a global outpouring of applause for the German-born Ghanaian international's decision.

World football's ruling FIFA had yet to make an official statement about the incident but in an interview from the United Arab Emirates on Sunday FIFA president Sepp Blatter said Boateng was "wrong" to have walked off the pitch.

Both FIFA and UEFA have previously warned against players walking off the pitch in protest, and Blatter told The National newspaper: "Walk off? No. I don't think that is the solution.

"I don't think you can run away. This issue is a very touchy subject, but I repeat there is zero tolerance of racism in the stadium; we have to go against that."

Milan reacted quickly, declaring: "AC Milan reiterates its firm stance against racism, in whatever shape or form, and calls on the national and international sports bodies to adopt and implement necessary and effective measures."

In the wake of the Boateng incident some observers, including former AC Milan star Clarence Seedorf, had warned that the decision to leave the pitch threatened to "empower" a racist minority.

At Rome's Olympic stadium on Saturday Seedorf's fears rung true when some sections of Lazio's crowd were heard making monkey noises at Cagliari's Colombian striker Victor Ibarbo.

Although the majority of the home crowd jeered and whistled to drown out the racists, Cagliari's director general Francesco Marroccu was forced eventually to inform the fourth official.

The referee halted play momentarily to speak to both team captains and order a message to be relayed over the tannoy to warn fans the game would be suspended if the chants continued.

Lazio went on to win 2-1, but this latest incident threatens to reinforce the Rome-based side's reputation for harbouring fans with far right sympathies.

Earlier this season Lazio were fined for racist chanting in a Europa League game against Tottenham -- the English club with arguably the biggest Jewish support in the Premier League.

Upon seeing television pictures of Saturday's game, Boateng posted on Twitter: "Sad to see these racist chants 2 days after @KPBofficial leads #ACMilan off pitch after receiving similar abuse. very sad!!!"

Lazio president Claudio Lotito claims he has "worked hard" to prevent such behaviour on the part of fans since taking over at the club, but could not vouch for every individual supporter.

He said: "Lazio is always singled out as a racist club, which is not true: we have several black players in our team.

"However we can't control the actions of individual supporters. I can't put a policeman on every fan when there are 30,000 in the stadium."

Hagel to Be Obama's Defense Secretary Nominee


Jan 6, 2013 4:52pm







gty chuck hagel kb 121220 wblog Obama Will Nominate Chuck Hagel as Next Defense Secretary

(Junko Kimura/Getty Images)


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.
