A magnificent art gallery constructed by Frederick the Great of Prussia in Potsdam is celebrating its 250th anniversary this year, Art Daily reports.

The gallery at Sanssouci Park, part of Frederick the Great's palace complex, was home to his vast collection of Classical and (then) contemporary art. While it lost much of its collection over the years, especially during the Napoleonic Wars and WWII, it's still an impressive center for fine art.

To celebrate the anniversary, the gallery is hosting "The Most Beautyful Gallery - Revisiting the Picture Gallery of Frederick the Great," and has brought together much of the original collection that got dispersed across Europe. Paintings from various periods fill the walls, including examples from the Italian Renaissance and High Baroque as well as 17th century Flemish and Dutch works. The gallery also shows Frederick's passion for Classical sculpture. Even the walls are made of marble torn from ancient buildings.

Potsdam is only 23 miles from Berlin and makes a good day trip from the German capital.

"The Most Beautyful Gallery - Revisiting the Picture Gallery of Frederick the Great" runs until October 31.

At the Roman necropolis in Carmona, Spain, visitors are led to the popular "Elephant's Tomb," a large underground chamber that gets its name from a crude sculpture of an elephant found there.

Now archaeologists are saying it may not be a tomb at all, but rather a temple to one of the ancient world's most mysterious religions. A team from the University of Pablo de Olavide, Seville, has analyzed the structure and says it was once a mithraeum, an underground temple for the god Mithras.

Mithraism centered on secret rites centered on the mystical slaying of a bull was one of the most popular faiths in the last years of paganism. Several mithraeums are scattered about Europe, including in London, Mérida, and along Hadrian's Wall.

The archaeologists point out that its general shape, with a columned, three-chambered room leading to an area for altars, is the same as other mithraeums. They also found astronomical alignments. Sunlight would hit the center of the chamber during the equinoxes, and during the winter and summer solstices, the sun would light up the north and south walls respectively. As the sun shines through the window during the spring equinox, Taurus rises to the East and Scorpio hides to the West. The opposite occurred during the autumn equinox. Taurus and Scorpio figure prominently in the religion's astrological symbolism, with the God Mithras slaying a bull as a scorpion stings the animal's testicles.

It was only later that the temple was turned into a burial chamber, researchers say.

Carmona is less than 20 miles from Seville and is a popular day trip from there.

A new study has found a possible way to stop at least one species of mosquito from giving you malaria – by infecting them with a special strain of bacteria.

Researchers have found that infecting mosquitoes with the Wolbachia bacterium makes it nearly impossible for malaria to survive in the insects, thus keeping them from spreading it to humans, the BBC reports. The technique was tested on Anopheles stephensi, a species that ranges from the Middle East to Asia. An example is shown here in this Wikimedia Commons image. This remarkable photograph shows the insect sucking blood from a human. It's become so engorged it's actually ejecting extra blood from its rear end. Sorry if you were eating when you saw this but hey, it's in the name of science.

The bacteria passed from female mosquitoes to their offspring, opening up the possibility of infecting the entire species. Researchers followed 34 generations of infected mosquitoes and found the bacteria passed on through all of them. The results have been published in the journal Science. A study last year showed the same bacteria can be used to stop dengue fever.

The technique has not yet been tried on Anopheles gambiae, the main source of malaria in Africa.

This potential breakthrough in the fight against malaria is coming along at an important time, now that mosquitoes are developing a resistance to DEET.

A favorite destination in America's most famous Civil War battlefield faces an uncertain future as its owners are retiring and putting the building up for sale.

The American Civil War Wax Museum at Gettysburg, Pennsylvania, was opened in 1962 and is selling for $1.7 million, the Evening Sun reports. Being a popular tourist attraction, the current owners say they are confident someone will buy it and keep it open.

The museum features more than 300 life-sized wax figures like these of Confederate Generals Joseph Johnston and Robert E. Lee shown here courtesy Flickr user cliff1066. Many of the figures are arranged into scenes of important moments in the Civil War.

In addition to the museum and a large gift shop, visitors can see reenactors demonstrating Civil War-era weapons and equipment most weekends from April through October.

Remarkably, the museum was founded by a Polish immigrant named C.M. Uberman, who moved to the United States shortly after World War II. This demonstrates the fascination this era of American history has for people all around the world. Here in Spain, history buffs ask me about the Civil War more than all other periods of American history combined. Hopefully if they make it to Gettysburg they'll find the American Civil War Wax Museum alive and well.

When the news talks about the people of Jerusalem, it's usually to highlight their differences. While those certainly exist, there's more to it than that. People all have their own opinions and priorities and the folks living in Jerusalem are no exception. In this video, a group of Jerusalem residents are asked all the same question: if you had one wish, what would you wish for?

Their answers are surprising, and cut across religious, political and ethnic lines. There doesn't seem to be any agenda to this video, as the divisive comments (some quite nasty) are left in along with the heartwarming ones. Naturally, many address the big issues, while some are tied up in their own affairs. This reflects my own experiences in Israel, where people range from good to bad to just plain ugly.

But mostly good, and that's important to remember.

Not feeling healthy? Go hiking. Two new studies from the UK show that a hike, or even a good walk around the city streets, boosts mental and physical health.

A new survey by Ramblers, the British walking charity, found that a quarter of adults in Britain walk for an hour or less a week. And when they're talking about walking, they don't mean hitting the trails in the local nature reserve, they mean all types of walking, including walking to the shops, work or school. Presumably walking to the fridge to get another lager isn't included. Of the more than 2,000 people surveyed, a staggering 43 percent said they walked for only two hours or less a week.

The Ramblers cites government health advisers who recommend that you get 150 minutes of moderate physical activity a week. Walking counts in this, and is one of the easiest ways to get fit. Not only does it reduce the risk of several physical ailments like heart disease, it reduces weight and improves mental activity and emotional well being. It also saves money on gas and public transport.
The British Heart Foundation has more details on their webpage.

Another new study shows that being outside more is more beneficial than we generally think. While many people worry about the harmful effects of the sun, a new study by Edinburgh University has found that UV rays cause the body to produce nitric oxide, a compound that reduces blood pressure. Researchers suspect that the benefits of exposure to the sun may outweigh the risks.

For some reason, people sometimes mistake me for a terrorist. Once I got interrogated by an air marshal for merely looking out a window, and the following year in London I totally freaked out several people on a bus.

The second incident was, I suppose, partially my fault. I boarded a city bus with a large suitcase, which I put on the luggage rack. Since the rack was right next to the door, I moved a little away from it so I wouldn't be in the way.

For a couple of minutes I stood there, keeping an eye on my bag and not listening to the buzz of voices around me. One conversation, however, began to get my attention.

"I just don't think it looks right," a worried woman's voice said.

"Well, then mention it to the driver," a man said.

"I don't want to make a fuss," the woman replied.

"Look, you're worried about it just sitting there. You don't see the owner. So go up to the driver and mention it," the man said. He didn't sound worried himself. Instead he sounded a bit condescending.

I turned to them.

The second of May is a date that every Spaniard knows. In 1808 on that date, the Spanish people rose up against Napoleon and started a long struggle to kick his troops out of the country. They'd been occupied the year before when Spain's weak king had foolishly allowed French troops march through his territory to invade Portugal. Napoleon, being Napoleon, decided to keep both countries.

The Peninsular War, as it was called, was long and bloody. At first the Spaniards were outmatched, but they developed an effective guerrilla war that stymied the invaders. In fact the term guerrilla ("little war") originated in this conflict. The English moved in to help and in 1814 their combined forces kicked Napoleon's troops back into France.

All across Spain in the first week of May, communities hold festivals to commemorate battles and celebrate local heroes. Here in Cantabria in northern Spain, the municipality of Camargo holds a reenactment in honor of Pedro Velarde y Santillán, an artillery captain who was born in the town and died heroically on the first day of the uprising.

Camargo is a small place that most foreigners and even locals miss. We've lived ten minutes away from it for a year and we had to look up how to get there. Despite this obscurity, they put on a good show. A big street fair sold food and local crafts. Strangely there was French cheese and wine for sale, a rarity in a country with enough excellent cheese and wine that there's no need for imports. I suppose it was in the spirit of the occasion.

Jumbo Elephants may disappear from Tanzania within seven years if current poaching trends continue, Sabahi news service reports.

The Tanzania Wildlife Research Institute counted 109,000 elephants in 2009. In 2012, the number had sunk below 70,000. This is due to a surge in poaching. Elephant ivory commands high prices on the international black market. If current trends continue, the elephants could be entirely wiped out within seven years.

The decline in elephants is a step backwards. In the 1980s, during a period of heavy poaching and lax enforcement, the population dipped as low as 55,000. Thanks to better legal enforcement and protection, elephants made a major recovery. Now all that hard work may be ruined.

This comes after sobering news that rhinos are now extinct In Mozambique's Limpopo National Park. These localized extinctions make it hard for species to maintain a viable population. Groups of animals get smaller and further separated, reducing the available breeding stock.

More detail on the elephant situation in Tanzania can be found in this government report.

The Museum of Photography in Berlin has just opened an exhibition of nude photos from the turn of the last century.

"The Naked Truth and More Besides Nude Photography around 1900" brings together hundreds of nude photos from an era we normally associate with old-fashioned prudery. In fact, nude photos were incredibly popular at that time. They had existed since the earliest days of the medium, and by the 1880s it was getting much cheaper to reproduce photographs. This led to a boom in the distribution of all photos, nudes included.

Soon nudity could be seen in magazines, advertising, postcards, collectible cards found in cigarette packs and large-format posters. The exhibition looks at a range of different styles and purposes of nudes, ranging from artistic studies to the blatantly pornographic. Rural images and scenes from Classical myths were also popular, as were photos of the nudist movement, which was seeing its first wave of popularity at this time.
