The World's Only Penis Museum: What are Their Collections?

From gigantic whale penises to speck-sized field mouse testicles and lampshades made from bull scrotums, Iceland's small Phallological Museum has it all -- and recently put its first human member on display.

"This is the biggest one," founder and curator Sigurdur Hjartarson says, patting an enormous plastic canister. Inside was a liquid-immersed greyish-white mass as wide as a small tree trunk and as tall as a man.

Weighing 70 kilos and measuring around 170 centimetres, the Sperm Whale specimen "is just the front tip," he explained.

"The full penis could in fact be five metres and weigh something like 350 to 450 kilos -- but of course, the animal it came from weighed around 50 tonnes," says the 69-year-old retired headmaster, chuckling beneath his woolly, grey beard.

A total 276 specimens from all of Iceland's 46 mammals, along with a few foreign contributions, are on show at what may be the world's only penis museum.

The cramped room is filled with test tubes and glass containers in all shapes and sizes, holding formaldehyde-immersed offerings from whales, dolphins, walruses, redfish, goats, polar bears and rats, just to mention a few.

More Americans are Members of Facebook than Have Passports

A staggering 155 million Americans - 50 per cent of the population - are on the social network, while only 115 million people - 37 per cent - have a passport.

The number of U.S. citizens applying for passports has been rising over the last decade, but the proportion of people with the travel documents is still dwarfed by other countries.

Some 71 per cent of the population in the UK has a passport. But the U.S. is still way ahead of China, where only 1.5 per cent of the population can travel abroad.

Facebook, which was started by Mark Zuckerberg while he was a student at Harvard, has experienced phenomenal growth since it was launched in February 2004. There are now 750 million Facebook users worldwide, according to travel website Tripl, which compiled the figures.

Reasons given for the low proportion of Americans with passports include the costs of travelling abroad and the popularity of vacationing at home. Simon Winchester, who wrote 'The Best American Travel Writing', said that Americans to do have a history of international travel.

How much water do we really need?

The eight-glass formula doesn't fit for everyone. It depends on your gender, size, and level of activity, other studies note. The Institute of Medicine calls for adult men to drink 13 cups of fluid daily (which totals three liters, or a little more than four tall reusable water bottles) and women to have nine cups (2.2 liters, or about the amount found in three reusable water bottles). That number changes according to lifestyle.

The more active a person is, the more they will need to replace fluids. Larger people, pregnant and nursing women, and those who take dehydrating medications also will likely need to account for that by adding more water to their diet.

If you are active, it's also important to account for your environment when calculating how much fluid you need. If you are exercising in temperatures that are very hot (likely leading you sweat more) or very cold (which can stunt your ability to sense dehydration), are an endurance athlete, or are active in a high-altitude area, you will probably need to up your water intake.

First Photos of Beckhams' Baby Girl Harper Seven

David Beckham posted a photo on his Facebook page showingwife Victoria getting some rest with their newborn daughter. "I took this picture of my two girls sleeping," he wrote.

Victoria, 37, also tweeted a picture Sunday of David, 36, tenderly holding their newborn daughter. In the black and white photo, David cradles Harper Seven and sweetly touches her nose with his. She's "Daddy's little girl," Victoria explained.

Harper Seven was born July 10 at Cedars-Sinai in Los Angeles. David and Victoria also have three sons: Brooklyn, 12, Romeo, 8, and Cruz, 6.

On Thursday, the fashion designer tweeted that "baby Harper is the most beautiful baby girl I have ever seen. I have fallen in love all over again!" "We feel so blessed," she added. "And the boys love their baby sister so much."

Scientists Discover Lost World

An ancient landscape long ago submerged beneath the North Atlantic Ocean has been discovered by scientists.

Researchers found the 56million-year-old lost terrain, which they have likened to the mythical lost city of Atlantis, by analyzing data collected for oil companies using an advanced echo-sounding technique.

The 1.2mile-deep landscape is located in the North Atlantic west of the Orkney-Shetland Islands and has peaks that once belonged to mountains and eight major rivers.

It would once have risen up to 0.6miles above sea level and probably joined up with what is now Scotland, and may even have stretched as far as Norway, the scientists said.

Researcher Nicky White, from University of Cambridge, said: 'It looks for all the world like a map of a bit of a country onshore. 'It is like an ancient fossil landscape preserved 1.2miles beneath the seabed.'

The discovery came from data gathered by a seismic contracting company. A hi-tech echo-sounding technique was deployed that involved releasing high-pressured air underwater - this produced sound waves that traveled through sediment on the ocean floor. An echo would bounce back each time these waves happened upon a change in the terrain through which they were traveling.

The Brain Can be Trained to Erase Embarrassing Memories

According to the latest scientist study, they have proved that selective memory really exists and people can train their minds to erase embarrassing moments from their mind. Repressing bad memories for long enough can lead to us forgetting them completely, researchers claim.

Scientists used EEG scans to monitor the parts of the brain that became active when volunteers actively tried to forget something. They were also able to pinpoint the exact moment a memory is 'forgotten', and claim that long-term suppression of a memory is a sure-fire way of permanently erasing it.

A team from Lund University in Sweden said that mastering the technique could be useful for people who suffer from depression or post traumatic stress disorder, where constantly dwelling on upsetting or traumatic memories has a devastating effect on mental health. Lead researcher Gerd Waldhauser said: 'We know that "forgotten" or repressed feelings often manifest themselves as physiological reactions.

'Our volunteers were trained to forget neutral information in a controlled laboratory environment. Training to forget a traumatic event would be more complex.'

Study: Van Gogh's "self-portrait" actually his brother

Art researchers at Amsterdam's Van Gogh Museum said they have "discovered" a work by Dutch painter Vincent van Gogh - long thought to have been a self-portrait -- was in fact a picture of his younger brother Theo.

"According to current opinion, Vincent van Gogh never painted his brother Theo, on whom he was dependent," the Van Gogh Museum said in a statement.

But senior researcher Louis van Tilborgh now believed the 1887 painting of a man wearing a light-coloured hat and a dark blue jacket was in fact Van Gogh's brother Theo, Vincent's junior by five years.

"The conclusion is based on a number of obvious differences between the two brothers," said the museum, pointing out dissimilar features including the neatness of the subject's beard and his round-shaped ear, "something Vincent did not have."

"The form and colour of Theo's beard, more ochre than red, is also an indication" as well as the man's "eye-colour and the style in which he was dressed supports the new insight," the museum said.

"The portrait matches pictures of Theo," Van Tilborgh told the Dutch news agency ANP.

Theo van Gogh died six months after his older brother shot himself in a wheatfield at the age of 37 in Auvers, France, in July 1890.

Dog Smiles for the Camera

When the person taking this picture said, 'Smile for the camera,' they probably were only expecting to see one set of gnashers. But thanks to his unexpected human-like expression of happiness, this gleeful dog has become an internet sensation.

The chirpy canine, pictured grinning ear to ear with his smiling Martina Navratilova lookalike owner, is now something of a star after his picture began being shared on social networking sites like Facebook and Twitter.

However, this hound's fame is nothing yet compared to that of Riley, the bichon frise/poodle mix pictured smiling while celebrating its first birthday.

The young dog was photographed in a party hat, unable to contain his excitement, as he prepares to devour a cake by its owner Maureen Ravelo, from San Jose, California. The image has since spread like wildfire.

‘Riley always makes faces like this, and that’s the best part about him. He gives you a new facial expression every time that you forget he’s a dog,’ Ms Ravelo told Metro.

‘The most unique part about him is he thinks he’s human like us,’ she added.
