The Power Station of Art in Shanghai has opened a new exhibition by Andy Warhol, but the famous pop artist's portraits of Chairman Mao have been left out of the picture.

Agence France-Presse reports that the Andy Warhol Museum, which created the traveling exhibition, was told by the Chinese government that images of Mao would not be needed. Warhol painted many pictures of the Chinese revolutionary leader, such as this one hanging in Berlin shown here courtesy Wikimedia Commons.

As everyone knows, China has been reinventing itself as a capitalist superpower while still maintaining its Communist leadership. Images of Chairman Mao have been steadily disappearing from public display because the new China doesn't jive with his idea of a peasant revolutionary Communist state. Bringing up memories of his Cultural Revolution, which saw countless works of art destroyed, also doesn't sit well with Shanghai's new image as a center for the arts.

The traveling exhibition, titled "Andy Warhol: 15 Minutes Eternal," has already been to Singapore and Hong Kong and will run in Shanghai until July 28, at which point it will continue on to Beijing and Tokyo.

Green Spain has finally emerged from a miserable winter into a glorious if unreliable springtime, so it's time to get out and enjoy the region's natural beauty.

The northern coastal strip of Spain consisting of Galicia, Asturias, Cantabria and the Basque Region has the best outdoor and underground adventures the country has to offer. Its combination of scenic hikes and extensive caves is thanks to the predominance of karst, a type of stone the weathers quickly with water. As you can see from the picture above, rain turns exposed karst into strange, picturesque shapes. When water flows underground it carves out long caves.

One of the best places to see this at work is the Parque Natural de Collados del Asón in Cantabria. Less than an hour's drive from both Santander and Bilbao, this 11,700-acre natural park is cut through by the Asón River and several smaller streams. Those and the frequent rainfall have scoured the terrain into a series of gorges and cliffs. A network of trails provides lowland rambles past traditional farmhouses and challenging climbs up to rugged and snowy peaks. The dark mouths of several caves beckon to you from the trailside, but these aren't places to explore without training and preparation.

The weather was glorious the day we went. When you have a fine day here in the north, you get outside. Luckily, you don't need good weather to get some exercise. The next time I went out we were pelted with a chilly northern rain, perfect conditions to explore Green Spain's other outdoor attractions – its caves.

Caving is big here, with several organizations and adventure travel companies ready to show you the ropes. And for many caves, ropes are what you'll need. As water cuts through the stone, it often finds fissures and plunges downwards, gradually widening them into vertical shafts. Rappelling into Stygian darkness is one of the best thrills caving has to offer.

One cave where you don't actually need ropes is Cotera Cave, not far from the famous prehistoric painted cave of Altamira, 20 minute's drive outside of Santander. The entrance isn't terribly inviting – an almost invisible trail snarled with brambles leads to a low opening where cows take shelter from the rain. Cows, being cows, have left more than their hoof prints behind.

Before there was the museum, there was the cabinet of curiosities. Starting in the 16th century as Europe expanded its horizons during the Age of Exploration, the rich and powerful began to collect curios and display them. Their collections were eclectic – everything from strange weapons from distant islands to beautiful coral formations.

The objects were all put together in no particular order in one room or cabinet, which was sometimes called a Wunderkammer ("Wonder Room"). This blending of natural history and anthropology with no accounting for geography or time period allowed the viewer to see the world as a whole in all its rich diversity. Many of these collections became the nuclei for later museums that are still around today, while others are still preserved in their original state.

Ambras Castle in Austria has the Chamber of Art and Curiosities, a collection most famous for its many portraits of "miracles of nature", mostly people suffering from deformities, plus this guy who managed to survive a lance being stuck through his head. There's also a suit of samurai armor, silk artwork, mechanical toys and plenty more.

The Augsberg Art Cabinet in the Museum Gustavianum in Uppsala is a beautiful little piece with all sorts of panels and drawers devoted to various themes such as life, death and religion. Click on the first link for a cool interactive exhibit.

The tradition of the Wunderkammer is kept alive by some museums. The British Museum in London has the Enlightenment Gallery, which is jam-packed with busts, fossils, Greek vases, rare books, weapons, and Asian religious statues. The Museum der Dinge ("Museum of Things") in Berlin is a fascinating if somewhat random collection of, well, things.

Accra, the capital of Ghana, is an established point on the African tourism trail thanks to its good flight and cruise connections, its Anglophone accessibility, its beautiful beaches and the stability of the nation.

Less often seen, however, is Nima Market. Located in one of the poorest areas of the city and home to many migrants from rural Ghana and nearby countries coming to the big city in search of work, it is the heartbeat of the neighborhood. This video takes us on a slow walk through the stalls.

The best thing about this video is that the cameraman uses a lot of close-ups, giving us a shopper's-eye view of all the food for sale, from the delicious-looking tomatoes to the humongous snails. There are also a lot of fruits and vegetables most Westerners would have trouble naming.

While the produce and the clothing are colorful, you can see that all is not well in Nima. Many of the people have a careworn look, and the man selling shoes only wears a pair of battered flip-flops on his own feet. This blog post by Ghanean blogger and journalist Zainabu Issah highlights some of the challenges the vendors at Nima Market face.

The harder side of life is a part of travel that we can't shut our eyes to, and witnessing the struggles of people in other cultures can open our own minds. It's these insights that are often the most important part of our trip.

A proposed bus route from England to Pakistan has been delayed due to trouble getting permits, the BBC reports.

The proposed route is the brainchild of Tahir Khokher, transport chief for the Mirpur region of Pakistan-controlled Kashmir. The route starts in the northern English city of Birmingham, where many Pakistanis from the Mirpur region live, and runs 4,000 miles through Europe, Turkey, and Iran before reaching northeastern Pakistan and ending at Mirpur.

The problem, of course, is the route itself. It runs straight through Iran and continues on to Quetta in Pakistan, which is a popular hangout for Al-Qaeda. The Kashmir region, which has been the scene of conflict between Pakistan and India since those nations were formed, isn't exactly the safest place in the world either. A recent survey found Pakistan the seventh unfriendliest country in the world, right after Iran.

On the other hand, a trip will only cost £130 ($200), making it an awesome budget travel option for the adventurous.

The Daily Mail quotes a Birmingham Minister of Parliament expressing concerns that the route could be dangerous. There is also the question of whether it would be used as a low-cost conduit for terrorists.

Khokher says the problems with permits should be ironed out within a month. Stay tuned for more news about the 12-day bus ride through one of the toughest regions in the world.

A British court has found a man guilty of selling fake bomb detectors to Iraq and Georgia, the BBC reports. James McCormick, 56, of Langport, Somerset, was found guilty of fraud after making a fortune from detectors he knew didn't work.

He's estimated to have made some $76 million from the worthless devices, which were modeled after a novelty golf ball finder. In his sales pitches he claimed they could be set to find anything from bombs to money to drugs. Researchers found no scientific basis for his claims.

Both nations that bought the devices have serious problems with terrorism, and adventure travelers that venture to these places were put in danger by McCormick's greed. In Georgia last year, someone put a bomb under the car of an Israeli embassy staffer, and bombings in Iraq are a frequent occurrence.

The BBC says the devices are still at use at "some" checkpoints. When I was traveling in Iraq in October 2012, I saw them in use at every checkpoint I passed through, including the checkpoints to Baghdad airport. Many people already knew they didn't work; yet they were still used to "scan" every vehicle. Senior Iraqi officials were bribed to use government funds (i.e. U.S. taxpayer dollars) to buy the devices. Three of these officials are now serving prison terms.

McCormick lulled the Iraqi police and army into a false sense of security and endangered the lives of everyone in Iraq, including myself. To say this makes me angry doesn't even come close to what I feel towards this scumbag, and it makes me wonder about the other "security devices" we rely on. Last year the TSA removed backscatter x-ray body scanners from some airports for fear of cancer risks and replaced them with less harmful millimeter-wave scanners. The effectiveness of x-ray scanners has also been questioned.

I'm glad to see McCormick is finally facing justice, but I think he's been found guilty of the wrong thing. He didn't perpetrate fraud; he aided and abetted terrorism. He should spend the rest of his life in solitary confinement, kept company only by graphic photos of Iraq's bombing victims.

Dancing Queens, get dancing, an ABBA museum is opening in Stockholm.

ABBA The Museum will open its doors in the Swedish capital on May 7. It covers the complete history of the disco group and will display their gold records, crazy '70s costumes, and even reproductions of their recording studio and dressing rooms.

As visitors pass through the museum they'll be treated to different music in each room. One room is dedicated to ABBA's song "Ring, Ring" and has a phone that ABBA band members will occasionally call to have a talk with fans.

The Museum is a part of the new Swedish Music Hall of Fame, which has exhibitions on the history of Swedish popular music, a Hall of Fame dedicated to Sweden's stars, and temporary exhibitions.

You'll have to be a real ABBA fan to visit this place, though. Adult tickets cost 195 krona, or $29.54. At least the tickets get you into the Swedish Music Hall of Fame too.

Behind an eighteenth-century facade in downtown Oxford, just above a clothing shop, is a bedroom that was once used by William Shakespeare.

It was part of the Crown Tavern, owned by Shakespeare's friend John Davenant. The Bard frequently stopped in Oxford on his trips between Stratford-upon-Avon and London. A nearby courtyard may have hosted his troupe's performances.

Known as the Painted Room, it's been remarkably preserved since Elizabethan times and still has hand-painted wall decoration from the late 16th century. This rare artwork survived thanks to oak paneling installed in the following century, and was only rediscovered in 1927.

Part of the decoration includes a religious text:
"And last of thi rest be thou
Gods servante for that hold I best / In the mornynge earlye
Serve god devoutlye
Feare god above allthynge. . ."

This week the Oxford Preservation Trust is offering guided tours of the Painted Room. If you can't make it, BBC has posted a video tour of the room, led by some silly guy in an anachronistic tricorne hat. The Trust is also working on making the rooms permanently available to the public.

The Faroe Islands are a bit too remote to be on many people's bucket list and that's a shame. Halfway between Scotland and Iceland in the windy north Atlantic, they offer a rugged beauty equal to any adventure travel destination.

This shot from user kanelstrand from Gadling's Flickr pool was taken early one morning after some rain. The mixture of light and shadow, the deep color of the sea and of course the rainbow give you an idea of the allure of these distant islands.

That lonely little lighthouse shows that, indeed, some people really live here. In fact, about 50,000 people do in an autonomous nation under the Danish Realm. Amazingly, the islands were first settled by Irish and Scottish Christian hermits way back in the sixth century. St. Brendan may have visited on his fabled trip to America, followed by the Vikings. The modern Faroese are a tough people of mixed Scandinavian and Scottish descent who are proud of the life they've carved out of a harsh yet alluring corner of the world.
