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.

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.

Largest fake prime number holds 300 billion digits

A 300-billion-digit number is the biggest known pseudoprime, a number which looks like a prime but isn't. The techniques used to find this behemoth could help keep online transactions secure.

The first 10 digits are 1512269972 – but we can't give you the rest as the new number is so large that typing out the full thing eats up around a third of a terabyte. "I've got an external drive holding it," says co-discoverer Andrew Shallue of Illinois Wesleyan University in Bloomington. It dwarfs the largest known true prime, a 17-million digit monster announced last week.

Prime numbers can only be divided by themselves and 1. Figuring out which numbers are prime can be tricky, so mathematicians have developed various algorithms to speed up the search. One simple test is based on an observation by 17th-century mathematician Pierre de Fermat, who said that for any prime number p and whole number a, if you divide a^p – a by p, the remainder is 0. Unfortunately, that is sometimes also true when p is not a prime.

Finding fakes

There are just 43 of these Fermat pseudoprimes in the first million numbers, compared to nearly 80,000 primes. Primes form the building blocks of modern cryptography, so mistaking a pseudoprime for the real deal would make it easy for someone to steal your secrets. Mathematicians have developed more sophisticated tests since Fermat's that reduce these mistakes, but pseudoprimes still crop up unexpectedly.

To hunt out the fakes, Shallue and colleague Steven Hayman created an algorithm that looks at a list of numbers to find a subset that, when multiplied together, produces a particular target – in this case, a pseudoprime that passes Fermat's test. Finding the largest known pseudoprime shows that the algorithm is dramatically better than previous techniques, says Shallue, who presented it last month at the Joint Mathematics Meeting in San Diego, California.

"Finding this number is indeed an achievement," says Graham Jameson of the University of Lancaster, UK. However, the practical advance is the new algorithm, which could tell mathematicians and cryptographers more about the general properties of pseudoprimes, he says. "The more important problem is to establish just how uncommon these numbers are."

Eurozone recession deepens in Q4

BRUSSELS: The recession in the 17-nation eurozone recession deepened sharply in the fourth quarter of 2012, with the economy shrinking by 0.6 percent from the previous quarter when it dropped 0.1 percent, official data showed on Thursday.

In the second quarter of 2012, the eurozone economy had contracted 0.2 percent on a sequential basis, meaning the recession has now lasted three quarters as the debt crisis has sapped growth and sent unemployment soaring.

Compared with output in the fourth quarter of 2011, the eurozone economy contracted 0.9 percent, according to Eurostat agency figures.

For the wider 27-member European Union, output fell 0.5 percent compared with third quarter 2012 when the bloc had eked out growth of just 0.1 percent to narrowly avoid being in recession, as defined as two consecutive quarterly negative figures.

Compared with fourth quarter 2011, the EU economy shrank 0.6 percent.

Eurostat said that for 2012 as a whole, the eurozone economy contracted 0.5 percent and the EU 0.3 percent.

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.
