The Land of Twins – Brazilian Town Has 1,000 Percent Higher Multiple Birth Rate Than Global Average

Posted: 16 Apr 2014 04:29 AM PDT

Cândido Godói, a small town in Southern Brazil, has fondly been nicknamed: 'Twin Land'. As the name suggests, a phenomenal number of twins are born in the remote town each year – 10% of pregnancies result in multiple births. That’s nearly 1,000 percent higher than the global average. Right from the elderly to young children, most of the town's inhabitants are two-of-a-kind. Understandably, several theories have been proposed to explain this bizarre phenomenon – both scientific and outlandish in nature.

While some people have blamed a mysterious ingredient lurking in the town's water supply, most fingers point towards the Nazis. Specifically, towards Dr. Joseph Mengele (a.k.a. Angel of Death), one of Hitler's most ruthless followers. Mengele became infamous during the war for the horrifying medical experiments he conducted on prisoners. One of his sick experiments aimed at creating the perfect Aryan race for his Fuhrer. At this time, he also became interested in discovering the specific gene quirk that produces twins – to double the birth rate of the perfect race.

The Whispering Wall of the Barossa Reservoir and Its Amazing Parabola Sound Effect

Posted: 16 Apr 2014 03:16 AM PDT

When the Whispering Wall was built over a 100 years ago, no one had a clue about its amazing acoustic properties. The concrete dam was constructed by about 400 workers over the South Parra River in Barossa Valley between 1899 and 1902. The dam holds back the 4,515-mega liter Barossa reservoir that supplies water to several areas in southern Australia. The Whispering Wall has always been famous – the 9 storey structure was the first arch dam to be constructed in the region and at one point, the highest in all of Australia. But little did the builders know about the hidden properties of the engineering marvel they had created.

Because the dam is a hard and curved surface, any sound made on one end travels completely unobstructed to the other end. So you could have a perfectly normal conversation with someone standing on the opposite end of the dam (about 450 ft. away), as though they were right next to you! The voices can be heard quite clearly due to a phenomenon known as the parabola effect. The wall is so perfectly curved that it forms one sector of a circle. And the sound waves just bounce in a series of straight jumps all the way to the other end.

Black and Blond – The Origin of Blonde Afros in Melanesia

Posted: 16 Apr 2014 01:56 AM PDT

About a quarter of the Melanesian population in the Solomon Islands archipelago has an extremely unusual trait – dark skin with blond hair. The archipelago, located east of Papa New Guinea in Oceania, consists of a thousand islands inhabited by over half a million Melanesian people. They have the darkest skin in the world outside of Africa, but strangely, about one-fourth of the inhabitants sport blond afros.

This rare Melanesian characteristic has baffled scientists and genetic experts for years. Up until now, they have attributed the trait to inheritance – from the Europeans, especially the British, German and Australians, who have been associated with the island for hundreds of years. Several of the islands were under German jurisdiction in the 19th century. In 1893, the UK took southern Solomon Islands under their wing, declaring the region a protectorate. The rest of the islands were added to the protectorate at a later stage. And in the early 20th century, Australian and British companies set up coconut plantations on many of the islands.

So it isn't entirely unbelievable that the dark-skinned Melanesians got their blond hair from the growing influx of 'outsiders'. The locals, however, prefer not to go by that theory. They have been insisting for years that their blond hair is a result of a diet rich in fish and constant exposure to the sun. As it turns out, both theories are quite far from the truth. According to a recent investigation, random mutation might actually be the answer to the mystery of the Melanesian blonds.
