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 mil...

  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 lagoo...

  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 i...

  I’ve read that when the astronauts in space are out in the Sun, the temperature is +255 degrees and in the shadows the temperature is -255 degrees. Just what is the temperature of empty space? July 2003 Temperature has a precisely defined mathematical definition. For our purposes, we can say that temperature is proportional to the average kinetic energy of the random motion of a substance’s molecules. Kinetic energy is the energy something has by virtue of its motion. Molecules of all substances, even solids, have random motion and therefore an associated kinetic energy and temperature. Air molecules in a 70°F room are in vigorous random motion and thus possess kinetic energy and an associated temperature. In fact, air molecules move at hundreds of meters per second! Because these molecules are randomly moving, as many particles move up as down, and as many move left as right, they do not disturb objects. When we read that spacewalking astronauts experience certain temperature ex...

  10 Crazy Facts You Didn't Know About  Space There is so much about space, our solar system, and the galaxy that we still don't know!  Space is vast. With billions of galaxies and stars, and planets in our own solar system yet to be fully explored or understood, scientists' knowledge of space is always evolving.  There are, however, some really cool things we know about space right now!  We've compiled a list of what we think are ten stellar facts that we hope you'll think are out of this world!   1. SPACE IS COMPLETELY SILENT There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.  2. THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C. Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Did you know that Venus isn't the closest planet to the sun?  That is Mercury.  You would think that Mercury would then be the hottest, but Mercury ...

Twenty fun facts about the ocean The ocean covers more than 70 percent of the earth’s surface. ⠀ About 94 percent of the earth’s wildlife is found in the ocean. ⠀ More than 70 percent of the earth’s oxygen is produced by the ocean. ⠀ Five percent of the land belonging to the United States is surrounded by the ocean. ⠀ The sun is what makes the ocean blue. ⠀ The deepest part of the ocean is called the Mariana Trench, which is around 7 miles deep and is located in the South Pacific Ocean. ⠀ The water pressure at the bottom of the Mariana Trench is eight tons per square inch. This means the pressure there is enough to crush you. ⠀ Coral creates its own “sunscreen” by producing coral fluoresce that protects the algae found in coral. ⠀ The largest mountain range is found underwater and is called the Mid-Oceanic Ridge that is around 40,390 miles long. ⠀ The loudest sound ever recorded was made by an iceberg. In 1997, the sound was recorded and named, “The Bloom.” It was said to be heard from...

  7 Surprising Benefits of Exercise 1. Exercise is great for your brain. It’s linked to less depression, better memory and quicker learning. Studies also suggest that exercise is, as of now, the best way to prevent or delay the onset of Alzheimer’s disease, a major fear for many Americans. Scientists don’t know exactly why exercise changes the structure and function of the brain, but it’s an area of active research. So far, they’ve found that exercise improves blood flow to the brain, feeding the growth of new blood vessels and even new brain cells, thanks to the protein BDNF (brain-derived neurotrophic factor). BDNF triggers the growth of new neurons and helps repair and protect brain cells from degeneration. It may also  help people focus , according to recent research. 2. You might get happier. Countless studies show that many types of exercise, from walking to cycling, make people feel better and can even relieve symptoms of depression. Exercise triggers the release of che...
