Dog reunites you with lost plane items

Sherlock on the case: KLM pooch solves mysteries, wins hearts at Schiphol Amsterdam Airport.

• Beagle "Sherlock" returns items forgotten on KLM planes by passengers


• Sherlock's trainer focuses on muscle strength, endurance and socialization


• KLM launched service in response to high number of items left behind by passengers

(CNN) -- Warning: After seeing this achingly adorable video of KLM's newest employee in action you might be tempted to leave your gadgets behind on your next flight into Amsterdam.

Meet Sherlock, the appropriately named beagle tasked by the Royal Dutch Airlines with returning items forgotten on planes by passengers flying into Schiphol Amsterdam Airport.

"We train for muscle strength, endurance and, of course, socialization," says Dirk Van Driel, Sherlock's trainer.

"When you see the reactions of the passengers, that really is amazing."

Judging by the collective "awww" that rings out through the arrivals hall as Sherlock uses his remarkable sniffing powers to track down the owner of a forgotten iPhone, the dog is a hit.

"He can really do something no one else can"

KLM says Sherlock is part of a new lost and found team put together in response to the high number of queries about forgotten items the airline receives through social media.

Should the incredibly eager beagle not be around to help, the airline uses information such as seat numbers, phone numbers and public social media details to reunite passengers with their belongings.

"Personally, I think he's a real asset to the company," says Chantel Kremer of KLM's ground crew.

"And he can really do something no one else can."

Prized for their phenomenal sense of smell and ability to categorize scents, beagles are a familiar site in airports around the world.

Perhaps the most famous is the Beagle Brigade -- made up of teams of dogs that inspect luggage for restricted agriculture at U.S. airports.

What makes Sherlock stand out is that his presence doesn't bring the sense of unease some travelers may feel when one of these little guys starts snooping around their luggage for contraband produce.

My son was 'gasping for breath'

• Enterovirus D68 is sending children with breathing problems to the hospital


• David Nash fell ill in August with typical enterovirus symptoms


• The 3-year-old was hospitalized but has since recovered

(CNN) -- Enterovirus D68 has swept through 30 states since mid-August. What sets the virus apart from many others in the same family is its vicious symptoms: Instead of just causing a summer cold, it sends children to the hospital -- where they often end up in the intensive care unit, struggling to breathe.

David Nash from Tucker, Georgia, is one of those children.

At first his parents, Rachel and Rodney Nash, weren't too alarmed when David came down with a cough, runny nose and low-grade fever. But then the 3-year-old got sick very quickly.

David was in the first wave of children hit with Enterovirus D68. The virus struck early in states such as Georgia, where children headed back to school last month, but it then spread to states such as New York and Connecticut, where school began after Labor Day.

"There's no doubt the opening of schools has facilitated the transmission of Enterovirus D68," says Dr. William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center.

What parents should know

The Nashes shared with CNN the day-to-day story of their son's illness, hoping it might help families whose children have been recently diagnosed with what one pediatrician calls a "frightening" virus.

August 26

David's breathing gets worse.

"You could see him trying to pull the air in," Rachel Nash recalls. "His nostrils flared as he inhaled, and you could see the muscles in his neck and collarbone working extra hard."

Rodney Nash adds, "I remember as a kid my goldfish jumped out of the bowl. That's how he looked to me -- like a goldfish gasping for breath."

David receives oxygen in the emergency room at Children's Healthcare of Atlanta.

The Nashes take David to the emergency room at Children's Healthcare of Atlanta. His oxygen saturation rate is 86%. Healthy children's oxygen saturation is around 97%.

The doctors give David oxygen through his nose. Every two hours he gets nebulizer treatments, which are commonly used to treat asthma, to try to unclog his airways. David hates the mask and isn't cooperative.

David's saturation rate goes up to 88%, but that's not enough. He's admitted to the hospital.

David was admitted to the hospital on August 26.

In addition to the oxygen and breathing treatments, David gets an oral steroid to help shrink the swelling in his airways.

Even then, David is still wheezing.

The nebulizer treatments go from every two hours to every four. He still doesn't like them, but he doesn't protest as much as he did before.

At 8 a.m., David is taken off the oxygen and allowed to play. Nurses watch to see if he can breathe OK while riding a bike. If he can't, it means more time in the hospital.

Dr. Betsy John gives David a clean bill of health on September 16.

David's journey with Enterovirus D68 is fairly typical, says Dr. Mary Anne Jackson, division director of infectious diseases at Children's Mercy Hospital in Kansas City, Missouri.

Many children, however, get sick even faster. David was ill for about two days before he had to be hospitalized, but many of Jackson's patients have gone from healthy to severely ill in just a day, and they arrive at the hospital barely able to breathe.

"These kids were really struggling. Many can't even speak a sentence," she says. "It's frightening."

Her advice: If D68 has made its way to your community, and your child has asthma, or even, like David, just a history of allergies or occasional breathing difficulties, call your pediatrician and ask if there's anything you can do to protect your child.

The evolution of Bali's surf scene

"Indonesians believe that the ocean is very, very dangerous and the sea god is going to take you away," says Bali surfing pioneer Rizal Tandjung (pictured here) of why the locals were slow to join the island's surfing scene.

A Balinese surfer checks out the sunset waves at Kuta beach.

Padang Padang is one of the best surf spots in Bali, famous for its thundering barrels and fast waves.

Multiple surf schools can be found on Kuta Beach, Bali's busiest stretch of sand.

Almost 40 years old, surfing pioneer Tandjung owns multiple surf shops and is president of Hurley Indonesia/Bali.

• Bali's popularity among surfers grew with 1970s release of "Morning of the Earth" documentary


• Pro surfer Rizal Tandjung was one of the first locals to defy cultural norms and take up the sport


• Surf photographer Jason Childs says Indonesian surfers need to take things to the next level if they want to top the podium

Editor's note: This piece, and several others on Bali, complement the CNNGo TV series. This month's show features a tour with legendary Indonesian surfer Rizal Tandjung, a trip to the green fields of Ubud for some babi guling with artist Natisa Jones and a visit to a bar where the hip and beautiful play: www.cnn.com/cnngo

(CNN) -- "This is where it all started," says Rizal Tandjung, gazing out over a sandy shoreline lapped by dying breakers.

Almost 40 years old, Tandjung is one of Bali's surfing pioneers.

Picking up his first board at the age of eight, he's now a professional surfer, owner of multiple surf shops and president of a clothing company, Hurley Indonesia/Bali.

We're standing on Kuta Beach, a five kilometer stretch of white sand that's one of the most popular tourist areas on the Indonesian island of Bali.

Once a small fisherman's village, today's Kuta is anything but quiet.

Large commercial airplanes cruising into Ngurah Rai International Airport fly over the heads of surfers. Beach loungers are scattered down the shore as far as the eye can see, fighting for space with the multiple surf schools catering to tourists with "Endless Summer" dreams.

Tandjung walks us over to a little hut on the beach where we meet Made Switra, a surf shop owner, painter and leisure surfer who also grew up in Kuta.

"He's the one, the first generation, the first kid from the fisherman village to surf," says Tandjung.

Switra, tanned from all those hours in the water, sits with one leg propped up as he fiddles with his fishing pole.

"I started surfing from a fisherman boat. They had wood from a chair, so I started kind of boogie boarding with that and then found a few boards left from Westerners," Switra says.

Rizal Tanjung has been competing in the Rip Curl Cup every year since its inception in 2004.

Bali a late arrival to global surf scene

Switra and Tandjung are part of the breakthrough generation of Indonesian surfers.

Despite Bali being an obvious surf paradise, with its consistent waves and welcoming warm water, it wasn't until the late 1960s and 70s that it made its way onto the global surfing map.

Hawaii, Australia and California were the three big players.

But with the 1971 documentary "Morning of the Earth," Bali finally got its recognition, as scenes of Uluwatu's barreling waves caused surfers around the world to grip their wax in excitement.

With that recognition, Indonesian surfers eventually moved into the sport -- but not before overcoming some cultural taboos.

"Indonesians believe that the ocean is very, very dangerous and the sea god is going to take you away," explains Tandjung.

Many kids of his generation grew up not knowing how to swim, he says. Even today, some fisherman still can't.

Tandjung and Switra were viewed as rebels when they began surfing, ignoring their family's objections and defying any fear, he says.

Today, that societal unease is slipping away and fishermen see surfing as a business opportunity.

Using their boats to take surfers out to further breaks inaccessible from the shore -- such as a popular set of reef waves near Kuta's airport runway -- has led families to accept that surfing can pay the bills.

Jason Childs, a surf photographer based in Bali, has seen the evolution of surfing culture here.

"Life's too good and they know it," he says.

"They surf with the best surfers on the best waves on a daily basis."

Though Indonesian surfers have been gracing the pages of international surf magazines for about a decade, Childs believes it takes a certain fire in their bellies to get out of their comfort zone and to the next level.

Childs can't recall the first time he photographed Tandjung, but believes it must have been when he was about 16 years old.

He points out that Tandjung is not Balinese but Chinese Indonesian, so it's been even harder for him to be accepted into the local surf scene here.

"It's made him have to work harder."

And it's paid off, with Tandjung paving the way for future surfers.

Padang Padang is one of the best surf spots in Bali.

Will a Balinese surfer ever top the podium?

Nowadays, hardcore surfers head for Padang Padang in Bali's southern Uluwatu area.

Filled with high-speed waves, it has some of the best -- and most dangerous-- surf in Bali.

Just to the left of the rock enclosed beach are those world-famous barrels.

Tandjung has taken us here for a practice session leading up to the big annual Rip Curl tournament, which he's been chasing every year since its inception in 2004.

In tow is Tandjung's son, Varun, a name which means "god of the sea."

Varun and his friends beg to go out and try the big barrels.

The boy finally gets his wish and paddles out side by side with Tandjung, even getting to catch a few waves in between world-renowned pros like Bethany Hamilton.

Childs figures this new generation of Balinese surfers -- boys and girls -- is the best yet to come out of Bali, but it still could be another 20 to 30 years before a Balinese tops the surfing world.

But they'll find their way there with style and grace, he says.

"It's not very often you see an ugly Balinese surfer," says Childs.

"If you could build a surfer, the Balinese are close to perfect. They can jump to their feet effortlessly. They're beautiful to watch."

World's best nightlife cities

Whether in rooftop bars (like Sofitel So's HISO bar, pictured), dance clubs or trendy pubs, there's quality adventure in Bangkok.

In Buenos Aires, the weekend starts on Monday. In the Palermo neighborhood, Bar el Taller hosts plays, music shows and art exhibitions.

From NBA power forwards blowing signing bonuses to middle-agers gambling through a midlife crisis, Vegas attracts all sorts, with venues like the Marquee Nightclub at The Cosmopolitan (pictured).

Montreal North America's undiscovered gem. POP Montreal International Music Festival is an annual five-day party pumping out rock, indie-pop, electro, punk and hip hop.

In Barcelona, clubs don't get going until after 1 a.m. Ipanema Club has dancing and fancy cocktails over the Puerto Olimpico marina.

In London, there's fantastic music every night. The Wheel Barrow pub is one of more than 500 venues that hosts live music for Guinness' Arthur's Day celebrations.

Overshadowed by Rio de Janeiro, Sao Paulo's nightlife is diverse and intense. Club Yacht has electronic music in a nautical-themed setting.

It's not true that the "city never sleeps," but New York scores big because it offers something on any night of the week. Gramercy Theater often hosts music marathons for those wanting to dance.

If a city's mental health was determined by how many hours of the week its clubs weren't active, Berlin would be a lunatic in a straightjacket. The city's waterways are lined with "beach" bars, such as Club der Visionare.

Ibiza is nightclub Mecca. Venues, such as Pacha nightclub, aren't clubs, they're life experiences.

• Many travelers pass through Bangkok not realizing there's more to it than the seedy areas


• The first rule of Barcelona is that you don't stay on Las Ramblas


• Ibiza is a nightclub mecca and every party hound must make a pilgrimage there at least once

(CNN) -- Not everyone gets it.

But for some of us, travel is best expressed through celebration.

We prefer to exchange culture over the clinking of glasses and between the flashes of strobe lights.

Conversations punctuated by "Prost!" and "Salud!" show us more than any guidebook.

I view myself as a kind of international nightlife connoisseur.

As an entrepreneur, author and all-around life enthusiast, I've been around the world many times over.

And of everyone I know, I feel the most qualified to throw an absurd list like this together.

Each city is judged on four criteria, each given a score from one-to-10

MORE: Where to party like a local in Asia

1. Hours. How late each night and how many nights per week is the party good?

2. People. Is it a good crowd -- cosmopolitan, friendly and, yes, good looking?

3. Music. Judged on quality and variety offered in each city.

4. Experience. How likely you are to have an experience that you'll still be telling your friends about a decade from now.

I'm embarrassed to admit how much time I spent on this list (seriously, there was an Excel spreadsheet involved), but I finally narrowed it to 10 cities and I'm confident with the end result.

First, my honorary mentions: Hong Kong, Sydney, Miami, Stockholm, Tokyo and Tel Aviv.

My apologies party people, but the competition was stiff.

10. Bangkok

Hours: 7

A lot of travelers continue to pass through Bangkok not realizing there's more to it than the seedy dregs of Soi Cowboy, or the backpacker haven of Khao San Road.

Bangkok has developed a vibrant and classy side as the city has become more cosmopolitan.

Whether it's a series of gorgeous rooftop hotel bars downtown, rock bars near Ratchathewi, dance clubs just off Sukhumvit or trendy pubs in Thlonglor and Ekamai, there's legitimate, quality adventure to be had.

Best place to mingle with the locals: The young kids prefer RCA, while many of the city's beautiful people are drawn to the clubs on Sukhumvit Soi 11 or upscale Ku De Ta, among others.

"The Paris of the South" puts a New World spin on the insane Spanish practice of eating dinner at midnight and then dancing until dawn.

While living there, I remember trying to go home as the sun came up and an Argentinian friend telling me she wanted to go to an after-party instead.

It was eight in the morning. On a Wednesday.

Although not as affordable as it used to be, Buenos Aires is still a relative bargain among major world cities.

The locals love good rock music, too.

Wesleyan orders frats to go co-ed

Part of the campus of Wesleyan University in Middletown, Connecticut.

• Wesleyan University ordered fraternities to become co-ed in the next three years


• The Connecticut university has two all-male fraternities on campus


• One fraternity responds there are no facts about how this will improve on-campus safety

(CNN) -- Wesleyan University officials announced Monday that residential fraternities will be required to accept women and men as full members.

The policy change comes after consulting fraternity members, alumni and faculty, university spokesperson Kate Carlisle said. There are nonresidential Greek organizations, including one sorority, that will not be affected because they do not have on-campus houses.

"In the end, the decision is based on making our campus as fair, inclusive and equitable as possible, and reflects Wesleyan's tradition of progressive leadership," Carlisle said.

Wesleyan's board of trustees asked President Michael S. Roth in May to "prepare a plan to address the future of Greek life" after "highly publicized incidents of sexual violence." In a March 2014 lawsuit against Wesleyan's Xi Chapter of Psi Upsilon, a then-freshman student alleged she was raped in front of onlookers at the fraternity's on-campus residence.

An April 2014 Wesleyan Student Assembly survey that found 47% of respondents felt less safe in fraternity spaces also contributed to the review, Roth said in a statement.

"The trustees and administration recognize that residential fraternities have contributed greatly to Wesleyan over a long period of time, but we also believe they must change to continue to benefit their members and the larger campus community," Roth and Joshua Boger, the chair of the university's board of trustees, wrote in a joint statement on Monday.

The fraternities have three years to complete the co-educational transition.

Sex in California: Only a yes means yes

The Middletown, Connecticut, university has a current population of about 2,900 undergraduates with two all-male fraternity residences on campus, Psi Upsilon and Delta Kappa Epsilon.

Delta Kappa Epsilon International Fraternity, the organization's national governing body, said it "strongly" disagreed with the decision, calling the university's justification for the decision "vague."

"Remarkably absent from the University's statement are any facts -- even opinions -- about why Wesleyan feels it will be better off with co-educational fraternities. How can a highly rated liberal arts institution implement a major policy change, without even describing to those affected by it, the problem that you are intending to solve?"
