                   Physical Activity for Adults Physical activity plays an important role in both physical and mental health. People who are physically active tend to live longer, healthier lives. Active people are more productive, and more likely to avoid illness and injury ¹ . Whether it’s dancing, exploring, sports, or working out at the gym, safe and regular physical activity will keep the body moving and the heart pumping to provide immediate and long-term health benefits. At least a minimum of 30 minutes physical activity a day can: Lower risk of heart disease Lower cholesterol Lower blood pressure Lower risk of Type 2 diabetes Help manage weight Improve endurance, strength, flexibility Build stronger bones, muscles and joints Lower risk of osteoporosis  Reduce risk of falls Boost energy and mood Improve sleep On the other hand, a lack of physical activity can increase risks of developing preventable conditions, such as: Anxiety, stress, and feelings of depression High blood pre

  10 Computer Science Facts – Number 3 Will Surprise You! When you think of computer science, what comes to mind? If you’re like most people, you will see a person coding in a dark room. You may even think that computer science is all about difficult math and numbers. But there are many computer science facts that may surprise you. For starters, computer scientists often focus more on theory whereas computer engineers focus on hardware and developers on software. However, computer science is a big umbrella with a lot of subjects and career possibilities underneath it. In this article, we touch on some interesting facts about computer science degrees, job prospects, interesting statistics, surprising skills, and some fun historical facts. Let’s get going! 1. Computer Science is a Booming Market When it comes to earning a degree in computer science, it takes hard work and commitment. That’s why it’s good to know what may happen after you graduate. Computer scientists work in a variety of

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

  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 extrem
