Why the Dog Show Winner Looks Like a Monkey

Standing less than a foot tall and easily cradled in one of trainer Ernesto Lara's arms, Banana Joe made big news for a small dog when he became the first affenpinscher to win the Westminster Kennel Club dog show on Tuesday.

His short stature and flattened face might not make Banana Joe look like a typical winner: The name "affenpinscher" is German for "monkey terrier," and its mug is definitely simian in appearance. Now this lesser known breed is basking in the spotlight, monkey face and all. (Read "How to Build a Dog" in National Geographic magazine.)

Why the Flat Face?

People like dogs whose faces kind of look like people, with a squished-in nose and forward-facing eyes: Pekinese, bullmastiffs, and affenpinschers, to name a few. "It's mimicking the way humans appear," said Jeffrey Schoenebeck, a research fellow at the National Institutes of Health who has analyzed the development of shortened canine snouts. Several centuries ago, breeders probably sought out parents with a flat face. (Genetics note: Gene BMP3 likely contributes to a flat face in toy breeds.)

And so Banana Joe's mug reflects centuries of genetic manipulation. There's no advantage for the dog, Schoenebeck notes, except that humans would crave it more as a companion. (Related: Gallery of Dog Pictures.)

What About That Tongue?

Banana Joe sticks out his little pink tongue a lot. Maybe more than your run-of-the-mill canine. The reason may be the flat face. "There's probably less room in their mouth" for the tongue, said Schoenebeck. "It's hanging out."

Why so Small?

"The Affenpinscher comes from a terrier background," explained NIH senior staff scientist Heidi Parker, and like all terriers, it was bred to chase. The early affenpinschers' specialty was hunting down rats and other vermin for its owners. Breeding for a small size came later, as ladies started bringing affenpinschers into the home as lap dogs-and to keep away vermin that might otherwise hide in corners or under long skirts. Today's affenpinschers are in the 6-to-13 pound (3-to-6 kilogram) range.

But the dog's size hasn't given it an inferiority complex. "Most of these little guys do not realize they're as small as they are," Parker says. Toy dogs have been known to chase birds and other animals that rival them in size.

What Comes After Westminster?

Dog lovers may crave an affenpinscher. And that could cause problems if breeders try to produce more pups.

"You'll see some breeds go through sudden explosions, where they'll go from small numbers to really large numbers," says Parker. "Usually that means an increase in genetic diseases." There aren't a lot of potential parents for a purebred litter, so the odds of inbreeding, and its related diseases, go up.

And What About Banana Joe?

Now that he's made us aware of his breed, Banana Joe will retire from competition and live with his Dutch owner, free to fulfill his heritage as a lap dog.

Carnival Cruise Ship Hit With First Lawsuit

The first lawsuit against Carnival Cruise Lines has been filed and it is expected to be the beginning of a wave of lawsuits against the ship's owners.

Cassie Terry, 25, of Brazoria County, Texas, filed a lawsuit today in Miami federal court, calling the disabled Triumph cruise ship "a floating hell."

"Plaintiff was forced to endure unbearable and horrendous odors on the filthy and disabled vessel, and wade through human feces in order to reach food lines where the wait was counted in hours, only to receive rations of spoiled food," according to the lawsuit, obtained by ABCNews.com. "Plaintiff was forced to subsist for days in a floating toilet, a floating Petri dish, a floating hell."

The filing also said that during the "horrifying and excruciating tow back to the United States," the ship tilted several times "causing human waste to spill out of non-functioning toilets, flood across the vessel's floors and halls, and drip down the vessel's walls."

Terry's attorney Brent Allison told ABCNews.com that Terry knew she wanted to sue before she even got off the boat. When she was able to reach her husband, she told her husband and he contacted the attorneys.

Allison said Terry is thankful to be home with her husband, but is not feeling well and is going to a doctor.

"She's nauseated and actually has a fever," Allison said.

Terry is suing for breach of maritime contract, negligence, negligent misrepresentation and fraud as a result of the "unseaworthy, unsafe, unsanitary, and generally despicable conditions" on the crippled cruise ship.

"Plaintiff feared for her life and safety, under constant threat of contracting serious illness by the raw sewage filling the vessel, and suffering actual or some bodily injury," the lawsuit says.

Despite having their feet back on solid ground and making their way home, many passengers from the cruise ship are still fuming over their five days of squalor on the stricken ship and the cruise ship company is likely to be hit with a wave of lawsuits.

"I think people are going to file suits and rightly so," maritime trial attorney John Hickey told ABCNews.com. "I think, frankly, that the conduct of Carnival has been outrageous from the get-go."

Hickey, a Miami-based attorney, said his firm has already received "quite a few" inquiries from passengers who just got off the ship early this morning.

"What you have here is a) negligence on the part of Carnival and b) you have them, the passengers, being exposed to the risk of actual physical injury," Hickey said.

The attorney said that whether passengers can recover monetary compensation will depend on maritime law and the 15-pages of legal "gobbledygook," as Hickey described it, that passengers signed before boarding, but "nobody really agrees to."

One of the ticket conditions is that class action lawsuits are not allowed, but Hickey said there is a possibility that could be voided when all the conditions of the situation are taken into account.

One of the passengers already thinking about legal action is Tammy Hilley, a mother of two, who was on a girl's getaway with her two friends when a fire in the ship's engine room disabled the vessel's propulsion system and knocked out most of its power.

"I think that's a direction that our families will talk about, consider and see what's right for us," Hilley told "Good Morning America" when asked if she would be seeking legal action.

Comet rain took life's ingredients to Jupiter's moons

Dust made from pulverised comets may have seeded Jupiter's moons with the raw ingredients for life. That includes Europa, which is thought to harbour a liquid ocean beneath its icy crust.

Jupiter has two kinds of natural satellites: large spherical moons and smaller lumpy bodies that follow elongated orbits. Chemical analysis of the irregular bodies suggests they are made of the same stuff as asteroids and comets. This means they are probably rich in the carbon-containing compounds that are key to life on Earth.

It is thought that a gravitational reshuffling of the planets some 4 billion years ago shook up distant belts of space rocks and sent many of them hurtling towards the sun. Some got caught in Jupiter's orbit and became the irregular satellites. The objects frequently collided as they settled into their new orbits, creating dust as fine as coffee grounds.

Blanketed moons

Models say that Jupiter should have captured about 70 million gigatonnes of rocky material, but less than half that amount remains as irregular moons. "So what happened to all the stuff?" asks William Bottke of the Southwest Research Institute in Boulder, Colorado.

His team ran simulations of the irregular moons' evolution and found that their ground-up material would have fallen towards Jupiter, dragged by gravity and blown by the solar wind. About 40 per cent of it would have hit Jupiter's four largest moons. Most of this landed on Callisto (Icarus, doi.org/kff). The rest hit Ganymede and then Europa.

That's roughly consistent with images from the Galileo spacecraft, which show dark material on Ganymede and Callisto. "Callisto literally looks like it's buried in dark debris," says Bottke, while Ganymede has a lot of similarities but less dark stuff on its surface.

Sinking carbon

But the surface of Europa is relatively clean. Cracks cover the moon's crust, which suggests it has cycled material from deeper inside, so the carbon-rich debris may have been incorporated into the ice and even made it into the ocean, says Bottke. "Would it be important in Europa's ocean? It's hard to say," he says. "But it is kind of interesting to think about."

Bottke's calculations only set a lower limit on the amount of carbon-rich material that could have ended up in Europa's ocean, says Cynthia Phillips of the SETI Institute in Mountain View, California, who studies Europa.

"This could potentially be an even larger source of astrobiologically interesting material for the ocean layer than the authors of this paper estimate," she says.

No health effects from Fukushima: Japan researcher

TOKYO: A Japanese government-backed researcher said Friday no health effects from radiation released by the stricken Fukushima nuclear plant have been seen in people living nearby.

The pronouncement by Kazuo Sakai of Japan's National Institute of Radiological Sciences is the latest by authorities seeking to quell fears over the long-term effects of the disaster.

But it was dismissed by campaign group Greenpeace who said the government should not seek to play down health worries.

"Since the accident in Fukushima, no health effects from radiation have been observed, although we have heard reports some people fell ill due to stress from living as evacuees and due to worries and fears about radiation," Sakai said.

"We know from epidemiological surveys among atomic-bomb victims in Hiroshima and Nagasaki that if exposure to radiation surpasses 100 millisieverts, the risk of cancer will gradually rise.

"To put it the other way round, we can't say risk of cancer will rise if you are exposed to radiation lower than 100 millisieverts," he said, adding that most people measured had radiation exposure of 20 millisieverts or less.

Sakai said radiation is not at "the level we have to worry about its health effect," for people in Fukushima, taking into account exposure from the atmosphere and ingestion from food.

His comments came as the Fukushima prefectural government panel said this week three people who were 18 or younger when the nuclear crisis erupted in March 2011 have been diagnosed with thyroid cancer.

Radioactive iodine released in nuclear accidents tends to accumulate in thyroid glands, particularly in young people. In the 1986 Chernobyl disaster, a noticeable increase in thyroid cancer cases was detected among children in the affected area.

Referring to the thyroid cancers reported in Fukushima, Sakai said "there is no clear link between the cancers and exposure to radiation, as empirical knowledge says it takes several years before thyroid cancer is detected after exposure to radiation."

"It is important, however, to monitor these cases," he added, noting that comparison with the pre-accident situation and other regions was necessary.

Kazue Suzuki, nuclear campaigner at Greenpeace, who is not a scientist, said Japan should not try to play down the potential dangers.

"Japan should pour more energy into prevention of diseases including thyroid cancer than talking down the risk of low-level radiation."

"Even if there is no comparative epidemiological data, the government should err on the side of caution and carry out more frequent health checks among residents not only in Fukushima but in other prefectures," she said.

A massive undersea earthquake in March 2011 sent a huge tsunami crashing into Japan's northeast, crushing whole communities and sending nuclear reactors on the coast into meltdown.

Around 19,000 people were killed by the natural disaster, but no one is officially recorded as having died as a direct result of the radiation that spewed from the crippled units in the following months.

Why We Walk … and Run … And Walk Again to Get Where We're Going

You have to get to a bus stop to catch the once-an-hour express ... or to a restaurant to meet a friend ... or to a doctor's office. You've got maybe a half a mile to cover and you're worried you'll be late. You run, then you stop and walk, then run some more.

But wait. Wouldn't it be better to run the whole way?

Not necessarily.

A new study by an assistant professor of mechanical engineering at Ohio State University tests the theory that people subconsciously mix walking and running so they get where they need to. The idea is that "people move in a manner that minimizes energy consumption," said the professor, Manoj Srinivasan.

Srinivasan asked 36 subjects to cover 400 feet (122 meters), a bit more than the length of a football field. He gave them a time to arrive at the finish line and a stopwatch. If the deadline was supertight, they ran. If they had two minutes, they walked. And if the deadline was neither too short nor too far off, they toggled between walking and running.

The takeaway: Humans successfully make the walk-run adjustment as they go along, based on their sense of how far they have to go. "It's not like they decide beforehand," Srinivasan said. (Get tips, gear recommendations, and more in our Running Guide.)

The Best Technique for "the Twilight Zone"

"The mixture of walking and running is good when you have an intermediate amount of time," he explained. "I like to call it 'the Twilight Zone,' where you have neither infinite time nor do you have to be there now."

That ability to shift modes served ancient humans well. "It's basically an evolutionary argument," Srinivasan said. A prehistoric human seeking food would want to move in a way that conserves some energy so that if food is hard to find, the hunter won't run out of gas—and will still be able to rev it up to escape predators.

The study, published on January 30 in the Journal of the Royal Society Interface, doesn't answer that question of how we make such adjustments.

Runners: Take a Break if You Need It

The mix of walking and running is also something that nonelite marathoners are familiar with. Covering 26.2 miles might take less of a toll if the runner stops running from time to time, walks a bit, then resumes a jogging pace. "You use less energy overall and also give yourself a bit of a break," Srinivasan noted. (Watch: An elite marathoner on her passion for running.)

One take-home lesson is: Runners, don't push it all the time. A walk-run mix will minimize the energy you expend.

Lesson two: If you're a parent walking with your kid, and the kid lags behind, then runs to catch up, then lags again, the child isn't necessarily trying to annoy you. Rather, the child is perhaps exhibiting an innate ability to do the walk-run transition.

Potential lesson three: The knowledge that humans naturally move in a manner that minimizes energy consumption might be helpful in designing artificial limbs that feel more natural and will help the user reduce energy consumption.

The big question for Manoj Srinivasan: Now that he has his walk-run theory, does he consciously switch between running and walking when he's trying to get somewhere? "I must admit, no," he said. "When I want to get somewhere, I just let the body do its thing." But if he's in a rush, he'll make a mad dash.

"Talk to you tomorrow," he signed off in an email to National Geographic News. "Running to get to teaching now!"

Nightmare Ends: Passengers Leave Disabled Ship

After five days without power in the Gulf of Mexico, the more than 4, 000 people aboard the Carnival Triumph returned home to the U.S., with many of them telling their horror stories for the first time.

Passengers began to disembark the damaged ship around 10:15 p.m. CT Thursday in Mobile, Ala. The last passenger disembarked the ship at 1 a.m. local time, according to Carnival's Twitter handle.

Passenger Brandi Dorsett was thankful to be home, especially for her mother who was with her on the ship. Dorsett said she wasn't pleased with the doctor on staff.

"My mother is a diabetic and they would not even come to the room because she cannot walk the stairs to help her with insulin. She hasn't had insulin in three days," Dorsett said.

The Carnival Triumph departed Galveston, Texas, last Thursday and lost power Sunday after a fire in the engine room disabled the vessel's propulsion system and knocked out most of its power.

After power went out, passengers texted ABC News that sewage was seeping down the walls from burst plumbing pipes, carpets were wet with urine, and food was in short supply. Reports surfaced of elderly passengers running out of critical heart medicine and others on board squabbling over scarce food.

"It's degrading. Demoralizing and then they want to insult us by giving us $500," Veronica Arriaga said after disembarking the ship.

Passengers were already being given a full refund for the cruise, transportation expenses and vouchers for another cruise. Carnival Cruise Lines is now boosting that offer to include another $500 per person.

As the ship docked, passengers lined the decks of the Triumph, waving and whistling to those on shore. "Happy V-Day" read a homemade sign made for the Valentine's Day arrival and another, more starkly: "The ship's afloat, so is the sewage."

Some still aboard chanted, "Let me off, let me off!" and "Sweet Home Alabama."

Kendall Jenkins was one of many passengers that were photographed kissing the ground when they exited the ship. Jenkins, like many passengers, created makeshift beds out of lounge chairs on the ship's deck after the raw sewage smell became too much to contend with.

"We kind of camped out by our lifeboat. We would have nightmares about Titanic basically happening," passenger Kendall Jenkins told ABC News Radio.

"I am just so blessed to be back home," she added.

WATCH: Carnival CEO Gerry Cahill Apologizes to Passengers

Approximately 100 buses were waiting to take passengers on the next stage of their journey. Passengers had the option to take a bus ride to New Orleans or Galveston, Texas, where the ill-fated ship's voyage began. From there, passengers will take flights home, which Carnival said they would pay for.

Inside the buses, Carnival handed out bags of food that included French fries, chicken nuggets, honey mustard barbecue sauce and apples.

Deborah Knight, 56, decided to stay in Mobile after the arduous journey was over rather than board a bus for a long ride. Her husband Seth drove in from Houston and they checked in at a downtown Mobile hotel.

"I want a hot shower and a daggum Whataburger," said Knight.

She said she was afraid to eat the food on board and had gotten sick while on the ship.

Cruise Ship Newlyweds Won't Be Spending Honeymoon on a Boat

For 24-year-old Brittany Ferguson of Texas, not knowing how long passengers had to endure their time aboard was the worst part.

"I'm feeling awesome just to see land and buildings," Ferguson said, who was in a white robe given to her aboard. "The scariest part was just not knowing when we'd get back," she told The Associated Press.

Carnival president and CEO Gerry Cahill praised the ship's crew and told reporters that he was headed on board to apologize directly to its passengers shortly before the Carnival Triumph arrived in Mobile.

"I know the conditions on board were very poor," Cahill said Thursday night. "I know it was very difficult, and I want to apologize again for subjecting our guests for that. ... Clearly, we failed in this particular case."

Luckily no one was hurt in the fire they triggered the power outage, but many passengers aboard the 900 foot colossus said they smelled smoke and were living in fear.

The computer that never crashes

A revolutionary new computer based on the apparent chaos of nature can reprogram itself if it finds a fault

OUT of chaos, comes order. A computer that mimics the apparent randomness found in nature can instantly recover from crashes by repairing corrupted data.

Dubbed a "systemic" computer, the self-repairing machine now operating at University College London (UCL) could keep mission-critical systems working. For instance, it could allow drones to reprogram themselves to cope with combat damage, or help create more realistic models of the human brain.

Everyday computers are ill suited to modelling natural processes such as how neurons work or how bees swarm. This is because they plod along sequentially, executing one instruction at a time. "Nature isn't like that," says UCL computer scientist Peter Bentley. "Its processes are distributed, decentralised and probabilistic. And they are fault tolerant, able to heal themselves. A computer should be able to do that."

Today's computers work steadily through a list of instructions: one is fetched from the memory and executed, then the result of the computation is stashed in memory. That is then repeated – all under the control of a sequential timer called a program counter. While the method is great for number-crunching, it doesn't lend itself to simultaneous operations. "Even when it feels like your computer is running all your software at the same time, it is just pretending to do that, flicking its attention very quickly between each program," Bentley says.

He and UCL's Christos Sakellariou have created a computer in which data is married up with instructions on what to do with it. For example, it links the temperature outside with what to do if it's too hot. It then divides the results up into pools of digital entities called "systems".

Each system has a memory containing context-sensitive data that means it can only interact with other, similar systems. Rather than using a program counter, the systems are executed at times chosen by a pseudorandom number generator, designed to mimic nature's randomness. The systems carry out their instructions simultaneously, with no one system taking precedence over the others, says Bentley. "The pool of systems interact in parallel, and randomly, and the result of a computation simply emerges from those interactions," he says.

It doesn't sound like it should work, but it does. Bentley will tell a conference on evolvable systems in Singapore in April that it works much faster than expected.

Crucially, the systemic computer contains multiple copies of its instructions distributed across its many systems, so if one system becomes corrupted the computer can access another clean copy to repair its own code. And unlike conventional operating systems that crash when they can't access a bit of memory, the systemic computer carries on regardless because each individual system carries its own memory.

The pair are now working on teaching the computer to rewrite its own code in response to changes in its environment, through machine learning.

"It's interesting work," says Steve Furber at the University of Manchester, UK, who is developing a billion-neuron, brain-like computer called Spinnaker (see "Build yourself a brain"). Indeed, he could even help out the UCL team. "Spinnaker would be a good programmable platform for modelling much larger-scale systemic computing systems," he says.

This article appeared in print under the headline "Machine, heal thyself"

Build yourself a brain

The systemic computer takes its lead from nature (see main story), but so does Spinnaker, an ambitious project at the University of Manchester, UK, to build a one-billion-neuron computer from microchips. The idea is to create a supercomputer that works just like the human brain using the same ARM chips that power most smartphones. The team wants to do parallel simulation of large-scale neural networks using the equivalent of 1 per cent of the human brain's neuron count. They are well on their way: using chips that model 1000 neurons each, their system has created the equivalent of 750,000 neurons. "We're advancing slowly but steadily," says project leader Steve Furber.

French medical body for euthanasia in "exceptional" cases

PARIS: France's medical ethics council said Thursday that euthanasia should be allowed in exceptional cases and when suffering patients make "persistent and lucid requests."

Invoking a "duty to humanity," the body said that euthanasia should be reserved for "exceptional cases" like putting an end to "prolonged suffering", or "unbearable" pain.

President Francois Hollande had referred a report on allowing assisted suicide to the council to examine the precise circumstances under which such steps could be authorised with a view to producing draft legislation by June.

"The existing legislation does not meet the legitimate concerns expressed by people who are gravely and incurably ill," Hollande had said.

The report submitted to the council said physicians should be allowed to authorise interventions that ensure quicker deaths for terminal patients in three specific sets of circumstances.

In the first case, the patient involved would be capable of making an explicit request to that effect or have issued advance instructions in the event of him or her becoming incapable of expressing an opinion.

The second scenario envisages medical teams withdrawing treatment and/or nourishment on the basis of a request by the family of a dying patient who is no longer conscious and has not made any instructions.

The third would apply to cases where treatment is serving only to sustain life artificially.

Researchers develop a more accurate car navigation system

Researchers say new navigation system can be installed on any vehicle, including a Volkswagen Touareg.

(Credit:
Josh Miller/CNET)

Driverless cars could get a big boost from a new system that researchers say will increase the accuracy of in-car satellite navigation systems by 90 percent.

Researchers say the system combines conventional GPS signals with data from sensors such as accelerometers and gyroscopes to determine a vehicle's position within six feet of its location, a dramatic reduction from the current margin of error of 50 feet. The system can be installed inexpensively in any vehicle, say researchers at Spain's Universidad Carlos III de Madrid, where the system was developed.

"We have managed to improve the determination of a vehicle's position in critical cases by between 50 and 90 percent, depending on the degree of the signals' degradation and the time that is affecting the degradation on the GPS receiver," David Martín, a researcher at the Systems Intelligence Laboratory, said in a statement describing the project.

The system aims to tackle the greatest challenge faced by conventional GPS systems in urban settings: loss or disruption of satellite signal due to interference created by buildings, trees, and tunnels. The new system uses contextual information and an algorithm that eliminates deviations caused by degradation or loss of signal from satellites.

The researchers have installed a prototype system on an "intelligent
car" with the goal of capturing and interpreting all the information available while driving a car. The team sees applications of the system in driverless car systems currently under development by Google and a handful of automakers.

"Future applications that will benefit from the technology that we are currently working on will include cooperative driving, automatic maneuvers for the safety of pedestrians, autonomous vehicles or cooperative collision warning systems," the team said.

Ultimately, the team hopes to develop a system that harnesses the sensors built in to smartphones, such an accelerometer, a gyroscope, a magnetometer, and GPS, as well as taking advantage of communications tools such as Wi-Fi, Bluetooth, and GSM.
