Fort Hood Hero Says President 'Betrayed' Victims

Three years after the White House arranged a hero's welcome at the State of the Union address for the Fort Hood police sergeant and her partner who stopped the deadly shooting there, Kimberly Munley says President Obama broke the promise he made to her that the victims would be well taken care of.

"Betrayed is a good word," former Sgt. Munley told ABC News in a tearful interview to be broadcast tonight on "World News with Diane Sawyer" and "Nightline."

"Not to the least little bit have the victims been taken care of," she said. "In fact they've been neglected."

There was no immediate comment from the White House about Munley's allegations.

Thirteen people were killed, including a pregnant soldier, and 32 others shot in the November 2009 rampage by the accused shooter, Major Nidal Hasan, who now awaits a military trial on charges of premeditated murder and attempted murder.

Tonight's broadcast report also includes dramatic new video, obtained by ABC News, taken in the immediate aftermath of the shooting, capturing the chaos and terror of the day.

Munley, since laid off from her job with the base's civilian police force, was shot three times as she and her partner, Sgt. Mark Todd, confronted Hasan, who witnesses said had shouted "Allahu Akbar" as he opened fire on soldiers being processed for deployment to Afghanistan.

As Munley lay wounded, Todd fired the five bullets credited with bringing Hasan down.

Despite extensive evidence that Hasan was in communication with al Qaeda leader Anwar al-Awlaki prior to the attack, the military has denied the victims a Purple Heart and is treating the incident as "workplace violence" instead of "combat related" or terrorism.

Al-Awlaki has since been killed in a U.S. drone attack in Yemen, in what was termed a major victory in the U.S. efforts against al Qaeda.

Munley and dozens of other victims have now filed a lawsuit against the military alleging the "workplace violence" designation means the Fort Hood victims are receiving lower priority access to medical care as veterans, and a loss of financial benefits available to those who injuries are classified as "combat related."

READ the Fort Hood Victims' Lawsuit

Some of the victims "had to find civilian doctors to get proper medical treatment" and the military has not assigned liaison officers to help them coordinate their recovery, said the group's lawyer, Reed Rubinstein.

"There's a substantial number of very serious, crippling cases of post-traumatic stress disorder exacerbated, frankly, by what the Army and the Defense Department did in this case," said Rubinstein. "We have a couple of cases in which the soldiers' command accused the soldiers of malingering, and would say things to them that Fort Hood really wasn't so bad, it wasn't combat."

A spokesperson for the Army said its policy is not to comment on pending litigation, but that it is "not true" any of the military victims have been neglected and that it has no control over the guidelines of the Veterans Administration.

Secretary of the Army John McHugh told ABC News he was unaware of any specific complaints from the Fort Hood victims, even though he is a named defendant in the lawsuit filed last November which specifically details the plight of many of them.

"If a soldier feels ignored, then we need to know about it on a case by case basis," McHugh told ABC News. "It is not our intent to have two levels of care for people who are wounded by whatever means in uniform."

Some of the victims in the lawsuit believe the Army Secretary and others are purposely ignoring their cases out of political correctness.

Trading places with us makes robots better teammates

I am not a natural team player: I hate to have to rely on other people performing well but, equally, I am devastated if I fear I have let them down. That makes working with me a tough brief for my latest teammate, Abbie, a bright orange, industrial robot arm. Together we are going to insert three screws into a tabletop.

It seems simple but, behind-the-scenes, a profound human-machine connection could emerge. I just need to meld my mind to her software brain.

Whether humans and robots can bond as teammates used to be a theoretical concern. Factory robots tend to sit in cages, safely cordoned off from their human colleagues, so the two cannot touch, let alone collaborate. That is starting to change.

Baxter, a robot that can work safely beside humans, was launched by Rethink Robotics of Cambridge, Massachusetts, at the end of last year. Meanwhile, the US National Institute of Standards and Technology is creating safety standards for us to share workspace with robots by 2014.

To fully exploit this opportunity, Stefanos Nikolaidis, one of Abbie's programmers, and his supervisor, Julie Shah, want to teach robots to work fluidly with people and be better at anticipating their actions – as well as winning their trust. To do this, they have turned to human psychology.

My collaboration with Abbie will be based on a psychological technique called cross-training, in which members of a team work more effectively if they swap roles in preparation for a task. The rationale is that they will converge on a shared plan – or mental model – to complete the task, leading to fewer errors on the day.

Will the same be true for Abbie and me? From the beginning, the chips are stacked against us – deliberately.

There are two ways to perform our task: Abbie can either get to work as soon as I have put the first screw in the hole, or wait until I have them all in place and then screw down all three in one go. I express a preference for the first option, so Nikolaidis loads Abbie's software brain with the exact opposite preference – to ensure the mind-meld is as hard as possible to achieve.

We rehearse in a virtual workshop and swap roles so I control a virtual Abbie wielding a screwdriver and she controls a virtual me. When she puts a screw in place I jump in to screw it down before she has moved onto the next one, even though she's programmed to expect me to wait.

When it is time to try the task for real, Nikolaidis uploads the updated version of Abbie's brain into the robotic arm and I don a black glove covered in red LEDs to make it easier for the robot to read my hand movements. We stand facing each other across a bench top drilled with three holes.

I know I have adapted as a result of the rehearsal but has Abbie? Abbie's machine-learning software analysed my behaviour as I carried out her role, which gave her a glimpse of my expectations of her. Because I performed it differently to the way she had been programmed, she should have modified her behaviour to meet my expectations. "The goal becomes not only to do the task, but in a way that is closer to the person's preferences," says Nikolaidis. We start the task Abbie's way but end up completing it in a hybrid fashion – she starts to do things my way once I've positioned the second screw.

I am not the only human capable of bonding with a robot. Shah and Nikolaidis asked 18 volunteers to cross-train with virtual Abbie too. Those who cross-trained also stood closer to Abbie, spent more time moving at the same time as her – a sign of fluidity that perhaps arose from greater trust – and said they believed that Abbie had "learned their preferences". The results will be presented on 4 March at the Human-Robot Interaction conference in Tokyo, Japan.

Disappointingly, I didn't feel an eerie connection to my robo-teammate, but perhaps that is a sign of how well the training worked. "The fact that you weren't thinking about it at that level – or stressed out – that's a success of cross-training too," says Shah.

US tornadoes strike southern states, 60 injured

MIAMI: Several powerful tornadoes ripped through the southern US states of Mississippi and Alabama injuring at least 60 people and destroying hundreds of homes at the weekend, emergency officials said Monday.

The city of Hattiesburg in Mississippi's Forrest County bore the brunt of the storms, with heavy rain continuing to lash the region and create a risk of flooding.

"Two people were critically hurt in Lemar County right next to Hattiesburg, but no deaths have been reported at this stage," Greg Flynn, a spokesman for the Mississippi Emergency Management Agency (MEMA), told AFP.

"Around 60 people are reported injured, but fortunately most injuries are minor," he said.

The bad weather, however, destroyed hundreds of homes and caused damage to the campus of the University of Southern Mississippi, authorities said.

A spokeswoman for the Alabama Emergency Management Agency (AEMA) said that while the area was hit by bad weather on Sunday it had so far received no reports of injuries.

The National Weather Service said flooding and flash flooding will become a concern if rainfall continues to add up across the lower Mississippi valley.

Holograms of Holocaust survivors let crucial stories live on

A hologram of Holocaust survivor Pinchas Gutter interacts with onlookers during a demonstration of the New Dimensions in Technology project. (Click to enlarge.)

Pinchas Gutter has told his story many times. Of the horrors of childhood in the Warsaw Ghetto. Of being ripped away from his parents and 10-year-old twin sister the day the family arrived at Poland's Majdanek concentration camp, never to see them again. Of barely surviving a brutal Nazi prisoner "death march" away from front lines and allied forces. Of his liberation in 1945.

The story never loses its power, its agony, or its moments of hope. Only this time it's not the 80-year-old Gutter who's telling his tale, but a Princess Leia-like full-body holograph of him. Gutter's digital representation is a product of New Dimensions in Testimony, a high-tech initiative to record survivors' first-person accounts for interactive 3D exhibits that live on long after the storytellers have passed.

I think it's going to be considerably more engaging and immersive and moving than if they're just up there on a video screen.
--Paul Debevec, USC Institute for Creative Technologies

"The effect that it gives is a lot more that that person is there in the room with you than that person was filmed some time ago somewhere else," says Paul Debevec, a professor of computer science at USC and associate director of graphics research at the school's Institute for Creative Technologies (ICT). "I think it's going to be considerably more engaging and immersive and moving than if they're just up there on a video screen."

USC is teaming with the USC Shoah Foundation Institute, and design firm Conscience Display, to develop installations that let students and others converse with the hyper-photorealistic life-size digital versions of the survivors. Viewers ask questions, and the holograms respond, thanks to Siri-style natural-language technology, also developed at USC, that allows observers to ask questions that trigger relevant, spoken answers.

The project relies on light-stage technology developed by ICT to record interviews using multiple cameras for high-fidelity playback. ICT has been creating digital versions of people with its Light Stage systems since the year 2000, but researchers are significantly enhancing the technology for the survivor project.

"Everything that we're doing is getting retooled and to some extent reinvented specifically for recording the testimony of a survivor," Debevec says, "to do it in a way that when we project it holographically, it's a very absolute literal playback of exactly the way they said it, exactly the way they looked when they were doing it."

Most notably, the USC team is building a Light Stage system that can for the first time holographically record a full body, and do so with more spatial and angular fidelity than the smaller facial-recording system the team has built and used for the project so far.

"It's the kind of project that really inspires you to push everything that much further, because it's such valuable content that we'll be recording," says Debevec, whose institute has contributed to such films as "The Curious Case of Benjamin Button" and "Avatar."

Recently, in an auditorium at USC's School of Cinematic Arts, the project's team demonstrated their efforts with sometimes wrenching footage of Gutter in 2D, and at a scaled-down size in holographic 3D. Once ICT's technology is ready, the survivors' interactive digital doppelgangers will appear full size in 3D.

Debevec acknowledges that even the most advanced technology can't replicate the experience of hearing a survivor's account in person. But as this aging population dwindles, so do opportunities for in-person testimonials in schools, museums, and the like. New Dimensions in Testimony aims to record survivor stories in a way that future generations can best relate to.

Gutter -- who was born in Lodz, Poland, and now lives in Toronto -- was just 7 when the war erupted. The project team filmed him in 3D as he told his story in front of a green screen on Light Stage 6, a dome lit by more than 6,000 LEDs that measures 26 feet in diameter and looks like something the minds at NASA might think up. Stephen Smith, executive director of the USC Shoah Foundation, asked Gutter hundreds of questions and will likely interview the additional survivors picked to participate in the project.

Those survivors will likely spend even more time on Light Stage 6. Whereas seven high-speed cameras captured about 3 hours of Gutter's testimony, future interviewees will be recorded for up to 12 hours with 50 high-definition cameras.

"Some of them will be zoomed in on their face, some of them will be zoomed in on their hands, and a lot of them will be covering the entire body, seated, head to toe," says Debevec, who imagines the holographic technique eventually being applied to scientists, political leaders, and other public figures of note.

Not like the Tupac hologram
The New Dimensions in Testimony project might evoke memories of rapper Tupac Shakur performing at a music festival from beyond the grave, but there are some key technological differences.

Holographic Tupac appeared courtesy of stacked 2D images projected onto a thin and nearly invisible screen. Holographic Gutter and other survivors will be projected into open space to create an even more heightened sense that they're actually present. Audience members, depending on where they're sitting, will be able to see the virtual survivors from different vantage points, as they would any real person sitting in a chair on-stage.

"If you're sitting [at] the front, you see that person from the front. If you're sitting to the right, you'll see them to the right," Debevec says. "Even as you just shift in your seat and move your head back and forth... the viewpoint will shift then, too, appropriately, and you'll get an effect called motion parallax, which is even a more strong and visceral sense of the three-dimensionality than you get with binocular stereo."

The project comes at a crucial time.

Approximately 500,000 Holocaust survivors remain worldwide, with about 120,000 of those residing in the United States, according to San Francisco's Tauber Holocaust Library and Education Program. Their average age is estimated to be 79.

"We lose many of our survivors every year," Debevec says. "We definitely feel the sense of urgency and that realistically it's going to be now or never."

Year of the Snake: The Serpent Behind the Horoscope

On February 10, people all around the world will ring in the Lunar New Year with paper lanterns and firecrackers. At the heart of it all sits the snake, a slithery reptile feared for its sharp fangs and revered for its undeniable charm. (Watch videos of some of the world's deadliest snakes.)

Those born in the Year of the Snake are said to be intelligent and quick thinking, but they can also be dishonest and prone to show off. Though based on Chinese astrology, some of these traits are similar to characteristics of the actual serpent.

Snakes are known to be great at outsmarting their predators and prey. Their colorful, patterned skin makes them some of the best tricksters in the animal kingdom. And despite a bad rap as frightening creatures, snakes never fail to fascinate scientists, explorers, and zoo-goers. (See pictures of snakes.)

With more than 3,400 recognized species, snakes exhibit incredible diversity in everything from behavior and habitats to skin colors and patterns.

"As a vertebrate lacking in limbs, all snakes look largely like other snakes, yet they succeed in tremendous diversity in multiple directions," said Andrew Campbell, herpetology collections manager at the University of Kansas Biodiversity Institute.

To usher in the Year of the Snake, Campbell and herpetologist Dennis Ferraro at University of Nebraska-Lincoln weigh in on some of the snake's qualities that the Chinese zodiac predicts people born this year will have.

Horoscope: Snakes have an innately elegant personality but can also be ostentatious at times.

In Nature: Snakes come in all different colors, patterns, and textures, making them some of nature's most visually stunning creatures.

According to Campbell, the utility of their coloring falls into two main categories: to use as camouflage and to warn predators to stay away.

Among the most beautiful are the emerald tree boa (Corallus caninus)—whose vibrant green body is decorated with white stripes resembling lightning bolts—and the Brazilian rainbow boa (Epicrates cenchria), characterized by its iridescent skin and the large black rings down its back.

For some snakes, the diversity in color occurs within the same species, which is why Ferraro tells his student not to identify snakes by colors. For example, the polymorphic bush viper (Atheris squamigera), many of which are green, also come in shades of yellow, orange, red, and blue, as captured in photographer Guido Mocafico's "Serpent Still Life" photo series.

Horoscope: The snake is known to be the master seducer of the Chinese zodiac.

In Nature: Female garter snakes (Thamnophis) have all the luck with the gentlemen.

When a female garter snake is ready to mate, she announces it by producing chemicals called pheromones. Males, upon encountering the scent, immediately come crawling out and gather around the female in a large, wriggling "mating ball."

The competition intensifies when a male passing by the ball tries to fool the others by producing a scent that mimics that of the female, said Ferraro.

As soon as his rivals are led off in the wrong direction, the trickster slides right in. In areas with smaller populations of garter snakes, each ball consists of about 12 males and one female.

But in places like Manitoba, Canada, where garter snakes travel to certain areas to mate after coming out of hibernation, a mating ball can have thousands of males and only a hundred females.

Horoscope: Though snakes don't often tell lies, they will use deception when they feel it's necessary and they think they can get away with it.

In Nature: When it comes to using trickery to catch dinner, or to hide from predators, snakes are no amateurs.

Their sneaky techniques range from tricking fish to swim right into their mouths, to playing dead when threatened, to using their wormlike tails to lure in prey.

The most cunning of them all is the two-headed snake. To protect against a sneak attack from behind, the two-headed snake's tail looks just like its head. While the business end looks for food, the snake coils up its body and rests its tail on top to look like it is on guard.

The tail can even mimic the behavior of a retreating snake to trick predators into thinking they're going face-to-face with their opponent.

Horoscope: When snakes get down to work, they are organized and highly efficient, and they work quickly and quietly.

In Nature: While snakes are often perceived as lazy, Campbell said people are mistaken. "What we perceive as shy, lazy, or inactive is really efficiency," he said.

"On average, they are bigger than other lizards and can build a lot of body mass. They do that by being efficient in feeding and traveling." In other words, snakes don't move very much because they don't have to.

When it comes to food, snakes catch prey that are significantly larger than them so they can eat less frequently. This reduces the time they spend hunting and thus makes them less vulnerable to falling victim to a predator themselves.

For Campbell, the most impressive hunter is the eastern diamondback rattlesnake (Crotalus Adamanteus), which is able to hunt and kill its prey very quickly using venom, so it doesn't have to travel far. "Because they don't have to do that, they can become relatively large and heavy, being able to build up body mass and not having to spend that energy hunting."

Horoscope: Snakes are charming, with excellent communication skills.

In Nature: For snakes, their visual and auditory senses don't mean much when it comes to communicating with each other.

Instead, they use their sense of smell and the chemicals produced by their musk glands. Unlike mammals, a snake picks up scent through the forks of its tongue.

When the snake retracts its tongue, it inserts the forks into grooves in an olfactory organ located at the roof of its mouth. Depending on which fork picks up a stronger scent, the snake knows in which direction to go when looking for prey or a mate.

It's when snakes are threatened that they use sight and sound, said Ferraro. Rattlesnakes, for example, shake their tails, making a loud rattling noise to ward off predators.

Benedict XVI First Pope to Resign in 600 Years

Pope Benedict XVI's unexpected announcement today that he will step down for health reasons makes him the first pontiff to resign in nearly 600 years, even catching the Vatican by surprise and setting off a chain reaction that will end with a conclave to elect a new pope before the end of March.

"My first reaction was this is, it's very startling," Cardinal Donald Wuerl, Archbishop of Washington, said. "I was totally unprepared for it. The second reaction was we're going to have to now think a little differently. This will be the first time in modern history that we've had a pope resign. How do we work with all of that?"

Announcing his decision in Latin during a meeting of Vatican cardinals, Benedict, 85, said he will resign Feb. 28, explaining that his role requires "both strength of mind and body."

FULL COVERAGE: Pope Benedict XVI Resignation

"After having repeatedly examined my conscience before God, I have come to the certainty that my strengths due to an advanced age are no longer suited to an adequate exercise of the Petrine ministry," he said. "I am well aware that this ministry, due to its essential spiritual nature, must be carried out not only by words and deeds but no less with prayer and suffering."

Pope Benedict XVI was the oldest pope to be elected at age 78 on April 19, 2005. He was the first German pope since the 11th century and his reign will rank as one of the shortest in history at seven years, 10 months and three days.

RELATED: Pope Benedict XVI Resigns: The Statement

The last pope to resign was Pope Gregory XII, who stepped down in 1415.

Vatican officials said they've noticed that he has been getting weaker, while Benedict said he is aware of the significance of his decision and made it freely.

Pope Benedict XVI Never Aspired to Be Pope: Historian

Vatican Communications Director Greg Burke told ABC News that he was surprised but not shocked by the announcement, and cited an interview in which Benedict said a pope not only could resign, but should resign, if necessary.

"[Pope Benedict] is slowing a bit, and there's nothing immediately serious or grave," Burke said. "He has an older brother. He just thought the demands of the job were too much for his physical well being."

INTERACTIVE: Key Dates in the Life of Pope Benedict XVI

Benedict's brother, Monsignor Georg Ratzinger, had shared his concerns about the pope's health in September 2011, telling Germany's Bunte magazine that he should resign if health issues made the work impossible. More recently, Ratzinger has apparently cited his brother's difficulty in walking and his age, saying that Benedict had been advised by his doctor to cease transatlantic trips and that he had been considering stepping down for months, according to the German DPA news agency.

Among other ailments, the pope reportedly suffers from arthritis and arthrosis -- a debilitating joint-degeneration condition -- and his declining health drew attention about a year ago when he used a cane at the airport on his way to a trip to Mexico and Cuba.

Benedict has been a less charismatic leader than his predecessor, John Paul II, but tending to the world's roughly 1 billion Catholics still requires stamina Benedict seems to believe he now lacks.

PHOTOS: Pope Benedict XVI Through the Years

"Obviously, it's a great surprise for the whole church, for everyone in the Vatican and I think for the whole Catholic world," the Rev. John Wauck, a U.S. priest of the Opus Dei, told "Good Morning America" today. "But, at the same time, it's not completely surprising given what the pope had already written about the possibility of resigning.

"It's clear in terms of his mental capacity he's in excellent shape, he's very sharp, and so when he says he's making this official with whole freedom, it's clear that that's the case, that makes one believe that this is an act taken out of a sense of responsibility and love for the church."

It is a road that leads back to the 1930s.

Ratzinger started seminary studies in 1939 at the age of 12. In his memoirs, he wrote of being enrolled in Hitler's Nazi youth movement against his will when he was 14 in 1941, when membership was compulsory. In 1943, he was drafted into a Nazi anti-aircraft unit in Munich. He says he was soon let out because he was a priest in training.

He returned home only to find an army draft notice waiting for him in the fall of 1944.

As World War II came to an end, the 18-year-old Ratzinger deserted the army. In May 1945, U.S. troops arrived in his town and he was sent to a prisoner-of-war camp.

Liver cancer survival time tripled by virus

The virus used in the vaccine that helped eradicate smallpox is now working its magic on liver cancer. A genetically engineered version of the vaccinia virus has trebled the average survival time of people with a severe form of liver cancer, with only mild, flu-like side effects.

Thirty people with hepatocellular carcinoma received three doses of the modified virus – code-named JX-594 – directly into their liver tumour over one month. Half the volunteers received a low dose of the virus, the other half a high dose. Members of the low and high-dose groups subsequently survived for, on average, 6.7 and 14.1 months respectively. By contrast, trials several years ago showed that sorafenib, the best existing medication for this cancer, prolonged life by only three months.

Two of the patients on the highest viral dose were still alive more than two years after the treatment. "It's a very substantial survival benefit," says Laurent Fischer, president of Jennerex, the company in San Francisco developing the treatment under the trade name Pexa-Vec.

Besides shrinking the primary tumour, the virus was able to spread to and shrink any secondary tumours outside the liver. "Some tumours disappeared completely, and most showed partial destruction on MRI scans," says David Kirn, head of the study at Jennerex. Moreover, the destruction was equally dramatic in the primary and secondary tumours.

"This clinical trial is an exciting step forward to help find a new way of treating cancers," says Alan Melcher of the University of Leeds, UK, who was not involved in the study. "It helps demonstrate the cancer-fighting potential of viruses, which have relatively few side effects compared with traditional chemo or radiotherapy," he says. "If it proves effective in larger trials, it could be available to patients within five years."

The fact that the virus appears able to spread to secondary tumours suggests that simply injecting the virus into the bloodstream may be effective. A trial to compare this treatment with injecting the virus directly into a tumour is under way.

Targeted at cancer

The virus has had a gene coding for an enzyme called thymidine kinase snipped out. The enzyme enables the virus to recognise and infect dividing cells. By removing the gene, the virus's developers have reduced the likelihood of healthy dividing cells being infected.

Instead, the virus exclusively attacks cancerous tissue, by targeting two genes that have increased activity in tumour cells. One genes is associated with an epidermal growth factor receptor, which stimulates the cancer to grow. The other is associated with a vascular endothelial growth factor, which enables the cancer to recruit its own blood supply. The virus reduces the activity of both genes, causing the infected cancer cell to wither and die.

What's more, the virus carries extra genes to prod the body's own immune system into action against the cancer. One produces granulocyte colony stimulating factor, a protein that encourages production of extra white blood cells at sites of infection. The other produces a protein not naturally found in humans, called Lac-Z, that earmarks infected cells for destruction.

Fischer says that to date, more than 200 people have received the virus, which has also shown promise against other types of cancer, including those of the kidney and skin. But he warns that not everyone sees a benefit. "We know why patients respond, but not why they don't," he says.

Three Korean doctors slain in north Nigeria: police

KANO, Nigeria: Men armed with knives slit the throats of three South Korean doctors in a pre-dawn attack Sunday in a volatile town in northeastern Nigeria in the latest in a spate of killings of foreigners in recent months, police said.

The attack in Potiskum also came just two days after gunmen killed at least 10 people in horrifying attacks on two Nigerian polio clinics in a new blow to the campaign to wipe out disease, but it was not clear if the incidents were related.

Yobe State police commissioner Sanusi Rufa'i would not say if the Islamist group Boko Haram, which has been active in Potiskum, was responsible for Sunday's killings, but that the attack was being investigated.

He said unknown attackers scaled the fence of an apartment housing the three doctors at around 1:00 am and slit their throats, initially describing the victims as Chinese.

"Further investigations have shown that the victims were Korean nationals and not Chinese as earlier stated. They were doctors from South Korea," Rufa'i told AFP, in comments confirmed by a senior military official in the state.

Residents said the Koreans, whose bodies were found by neighbours, were employees of the state ministry of health and had been living in the city for one year.

In Seoul, the foreign ministry said it was checking the reports, but noted that few Koreans live in the town.

"The chance that the slain would be Koreans is not high," a foreign ministry official told Yonhap news agency. "But we are checking further related situations via diverse channels."

A local resident said the bodies of the Koreans were found in their room by neighbours who alerted security agents,

"People became worried when the doctors did not open their door in the morning," one resident who did not want to be named told AFP.

He said the victims had their throats slit, but it was not immediately clear if the assailants also came with guns.

"It is still premature to point any accusing fingers but we have commenced an investigation to unravel the killings," said Rufa'i, adding: "No arrest has been made."

Sunday's attack was the latest in a spate of killings of foreigners, especially Chinese nationals, in the country's restive northeast.

In November, gunmen shot dead two Chinese construction workers in nearby Borno State, the stronghold of the Boko Haram extremists.

Three other Chinese nationals have also been killed in separate attacks in the region.

Although no group claimed responsibility for the attacks, they were similar to previous strikes against foreigners by Boko Haram.

Violence linked to Boko Haram is believed to have left some 3,000 people dead since 2009, including killings by the security forces.

The killings in Potiskum, which lies about 100 kilometres (60 miles) from the state capital Damaturu, followed attacks on other health workers in the northern city of Kano on Friday.

Nine women and a man were shot dead in two separate attacks in Kano after a local cleric denounced polio vaccination campaigns and some local radio stations aired conspiracy theories about the vaccine being a Western plot to harm Muslims.

Nigerian President Goodluck Jonathan condemned Friday's killings, describing them as "dastardly terrorist attacks" and vowed to track down the perpetrators.

Boko Haram has claimed to be fighting for the creation of an Islamic state, but its demands have shifted repeatedly and it is believed to include various factions. Criminal gangs and imitators are also suspected of carrying out violence under the guise of the group.

Nigeria, Africa's most populous nation and largest oil producer, is divided between a mainly Muslim north and predominantly Christian south.

Apple's reportedly testing curved glass for 'iWatch'

Is Apple eyeing an iWatch?

(Credit:
Sarah Tew and Christopher MacManus/CNET)

Like hands a clock, rumors that Apple is developing a Dick Tracy-like wristwatch have come around again.

The New York Times reports today that Apple is experimenting with wristwatch-like iOS devices that sport curved glass. The advantage of the "iWatch," as some have labeled it, is said to be in the company's expertise with curved glass.

The smart wristwatch notion isn't exactly groundbreaking: A lot of smartwatches, fitness bands, or some hybrid of the two, were talked up last month at
CES. Some of those devices include the long-awaited Pebble wristwatch, which made its debut at the conference, and the 007-inspired Martian Passport Watch.

Rumors of Apple working on just such a device have been circulating for months. A report from a Chinese blog last December held that Apple had partnered with Intel to develop an iOS wristwatch that would be Bluetooth-enabled and sport a 1.5-inch OLED screen.

Apple encouraged wearing previous versions of the
iPod Nano on wrists in 2011, with manufacturers selling watchbands that could be attached to the Nano to wear it as a wristwatch. However, Apple bumped up the size of the iPod Nano last year, leading to speculation that it was developing a wearable computer of its own.

CNET has contacted Apple for comment and will update this report when we learn more.

Year of the Snake: The Serpent Behind the Horoscope

On February 10, people all around the world will ring in the Lunar New Year with paper lanterns and firecrackers. At the heart of it all sits the snake, a slithery reptile feared for its sharp fangs and revered for its undeniable charm. (Watch videos of some of the world's deadliest snakes.)

Those born in the Year of the Snake are said to be intelligent and quick thinking, but they can also be dishonest and prone to show off. Though based on Chinese astrology, some of these traits are similar to characteristics of the actual serpent.

Snakes are known to be great at outsmarting their predators and prey. Their colorful, patterned skin makes them some of the best tricksters in the animal kingdom. And despite a bad rap as frightening creatures, snakes never fail to fascinate scientists, explorers, and zoo-goers. (See pictures of snakes.)

With more than 3,400 recognized species, snakes exhibit incredible diversity in everything from behavior and habitats to skin colors and patterns.

"As a vertebrate lacking in limbs, all snakes look largely like other snakes, yet they succeed in tremendous diversity in multiple directions," said Andrew Campbell, herpetology collections manager at the University of Kansas Biodiversity Institute.

To usher in the Year of the Snake, Campbell and herpetologist Dennis Ferraro at University of Nebraska-Lincoln weigh in on some of the snake's qualities that the Chinese zodiac predicts people born this year will have.

Horoscope: Snakes have an innately elegant personality but can also be ostentatious at times.

In Nature: Snakes come in all different colors, patterns, and textures, making them some of nature's most visually stunning creatures.

According to Campbell, the utility of their coloring falls into two main categories: to use as camouflage and to warn predators to stay away.

Among the most beautiful are the emerald tree boa (Corallus caninus)—whose vibrant green body is decorated with white stripes resembling lightning bolts—and the Brazilian rainbow boa (Epicrates cenchria), characterized by its iridescent skin and the large black rings down its back.

For some snakes, the diversity in color occurs within the same species, which is why Ferraro tells his student not to identify snakes by colors. For example, the polymorphic bush viper (Atheris squamigera), many of which are green, also come in shades of yellow, orange, red, and blue, as captured in photographer Guido Mocafico's "Serpent Still Life" photo series.

Horoscope: The snake is known to be the master seducer of the Chinese zodiac.

In Nature: Female garter snakes (Thamnophis) have all the luck with the gentlemen.

When a female garter snake is ready to mate, she announces it by producing chemicals called pheromones. Males, upon encountering the scent, immediately come crawling out and gather around the female in a large, wriggling "mating ball."

The competition intensifies when a male passing by the ball tries to fool the others by producing a scent that mimics that of the female, said Ferraro.

As soon as his rivals are led off in the wrong direction, the trickster slides right in. In areas with smaller populations of garter snakes, each ball consists of about 12 males and one female.

But in places like Manitoba, Canada, where garter snakes travel to certain areas to mate after coming out of hibernation, a mating ball can have thousands of males and only a hundred females.

Horoscope: Though snakes don't often tell lies, they will use deception when they feel it's necessary and they think they can get away with it.

In Nature: When it comes to using trickery to catch dinner, or to hide from predators, snakes are no amateurs.

Their sneaky techniques range from tricking fish to swim right into their mouths, to playing dead when threatened, to using their wormlike tails to lure in prey.

The most cunning of them all is the two-headed snake. To protect against a sneak attack from behind, the two-headed snake's tail looks just like its head. While the business end looks for food, the snake coils up its body and rests its tail on top to look like it is on guard.

The tail can even mimic the behavior of a retreating snake to trick predators into thinking they're going face-to-face with their opponent.

Horoscope: When snakes get down to work, they are organized and highly efficient, and they work quickly and quietly.

In Nature: While snakes are often perceived as lazy, Campbell said people are mistaken. "What we perceive as shy, lazy, or inactive is really efficiency," he said.

"On average, they are bigger than other lizards and can build a lot of body mass. They do that by being efficient in feeding and traveling." In other words, snakes don't move very much because they don't have to.

When it comes to food, snakes catch prey that are significantly larger than them so they can eat less frequently. This reduces the time they spend hunting and thus makes them less vulnerable to falling victim to a predator themselves.

For Campbell, the most impressive hunter is the eastern diamondback rattlesnake (Crotalus Adamanteus), which is able to hunt and kill its prey very quickly using venom, so it doesn't have to travel far. "Because they don't have to do that, they can become relatively large and heavy, being able to build up body mass and not having to spend that energy hunting."

Horoscope: Snakes are charming, with excellent communication skills.

In Nturea: For snakes, their visual and auditory senses don't mean much when it comes to communicating with each other.

Instead, they use their sense of smell and the chemicals produced by their musk glands. Unlike mammals, a snake picks up scent through the forks of its tongue.

When the snake retracts its tongue, it inserts the forks into grooves in an olfactory organ located at the roof of its mouth. Depending on which fork picks up a stronger scent, the snake knows in which direction to go when looking for prey or a mate.

It's when snakes are threatened that they use sight and sound, said Ferraro. Rattlesnakes, for example, shake their tails, making a loud rattling noise to ward off predators.
