10  AMAZING  FACTS ABOUT THE HUMAN BODY Take a look around you: the world is full of scientific marvels. From the atomic building blocks of life to the deepest depths of outer space, there are a lot of things to awe over. Add your body to the list. Yes, the human body is truly an incredible specimen. Don’t believe it? Take a look at these ten facts, you’ll be surprised at what you learn. Infants are born with approximately 300 bones, but as they grow some of these bones fuse together. By the time they reach adulthood, they only have 206 bones. More than half of your bones are located in the hands, wrists, feet, and ankles. Every second, your body produces 25 million new cells. That means in 15 seconds, you will have produced more cells than there are people in the United States. The largest bone in the human body is the femur, also known as the thigh bone. The smallest bone is the stirrup bone, which is located inside your ear drum. There is anywhere between 60,000-100,000 miles of blo

  Is Venice sinking? When will it happen? Venice’s waterways are what makes it such a unique and romantic place, but does a watery fate lie in store for this enchanting city? And if so, when will Venice sink? Acqua alta If you’re familiar with Venice you’ll probably already be aware of the ‘acqua alta’, or ‘high water’, which affects the city numerous times a year at higher tides. As a visitor, your trip may not coincide with this phenomenon, but if it does, you’ll find St Mark’s Square temporarily turned into a lake and raised boards provided for you to walk on. This fact of Venetian life may be alarming to the uninitiated, but it’s not an immediate cause for panic and it’s not why people say ‘visit Venice before it’s too late’. The increasing frequency with which the acqua alta occurs is thought to be a consequence of the management of the lagoon – in particular land reclamation and the deepening of underwater channels to accommodate tankers. Water moves more quickly in the lagoon as

  There are few places on Earth where flooding is not a concern. Any area where rain falls is vulnerable to floods, though rain is not the only cause. How floods form A flood occurs when water inundates land that's normally dry, which can happen in a multitude of ways. Excessive rain, a ruptured dam or  levee , rapid melting of snow or ice, or even an unfortunately placed  beaver dam  can overwhelm a river, spreading over the adjacent land, called a  flood plain . Coastal flooding occurs when a large storm or  tsunami  causes the sea to  surge inland . Most floods take hours or even days to develop, giving residents time to prepare or evacuate. Others generate quickly and with little warning. So-called  flash floods can be extremely dangerous , instantly turning a babbling brook or even a dry wash into rushing rapids that sweep everything in their path downstream. Climate change  is increasing the risk of floods worldwide, particularly in coastal and low-lying areas, because of its
