Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

Why are the Dutch so tall?
|
view preview
If you've ever been to the Netherlands, you probably noticed one of two things a) nearly everyone rides a bike or b) you're a lot shorter than everyone there. According to statistics, this countries population has gained an impressive 20 centimeters in the past 150 years and is now officially the tallest on the planet. While a rich diet and good health care is always a recipe for physical growth, a new study suggests something else is going on as well: The Dutch growth spurt may be an example of human evolution in action. The study, published online today in the Proceedings of the Royal Society B, shows that tall Dutch men on average have more children than their shorter counterparts, and that more of their children survive. That suggests ge ...

A 'multi-berry' tree

Meet Italy’s double tree, the Bialbero de Casorzo. That cherry tree on top isn't being parasitic - its roots have grown right through the hollow truck of the mulberry tree into the earth below, so there's no stealing of nutrients going on here.

Prohodna cave in Bulgaria looks like it has two eyes at the top
|
view preview
Known by tourists as the Eyes of God, the Prohodna cave is a typical karst cave in the north of Bulgaria and lies within one of the largest karst regions of the country. It is 262 meters long and easily accessible due to its two entrances on both sides of the cave. Prohodna cave is naturally lit because of these huge entrances and various holes in the ceiling. Two of these holes are situated next to each other and their almond-like symmetrical shape gave them the striking resemblance to giant eyes. Seen from a certain angle they resemble a face looking down and during the rain it even seems as if the eyes were crying. Not only is the cave a popular site for tourists and movie makers, it is also a good location for speleology (the scientific ...

Oldest freshwater lake on Earth
|
view preview
Lake Baikal in eastern Siberia is the oldest freshwater lake on Earth, and one of the largest and deepest, containing around one-fifth of the world's freshwater. In winter, it freezes over, and these beautiful transparent, turquoise masses of broken ice appear momentarily in March, caused by the unequal structure, temperature and pressure in the main body of the packed ice.

|
view preview
Tianducheng is a housing estate in China that's designed to evoke classical European charm. The suburb, located in the Zhejiang Province is also called the "Paris of the East", partially because it is home to the second largest replica of the Eiffel Tower in the world.
