Science
Science (arising from the Latin “scientia”, meaning knowledge) is the human effort to understand how the natural world works. Through a broad range of scientific disciplines, mankind uses both observational and experimental methods to observe natural phenomena, prove or disprove theories on those phenomena and expand proven scientific knowledge for advancements in many fields like medicine and engineering.
With the threat of disease and famine, scientists are always discovering new technologies that help humanity and the world. Due to diseases such as cancer and AIDS, money is constantly poured into studies that are devoted to developing cures and treatments. Not only that, but alternative energy is a fast growing market and as carbon-based fuel becomes more scarce, the world turns to scientists to discover alternative energy sources.

Understanding Food Science
Many of us take for granted the fact that we will have the safe food and water that we need to survive. We also take for granted the fact that it will be safe for consumption. Little do we know, there is much more that goes on behind the scenes than just simple growing, preparation, packaging, and cooking. There are strict guidelines to follow and scientists involved every step of the way.
Food science is the study of every aspect of food. It covers every step – from the harvesting and slaughtering to the cooking and consumption of food. It is classified as a life science, and scientists specializing in food science study microbiology, chemical engineering, and biochemistry, among others. They are responsible for the best way to grow crops, raising animals, preserving our food, and even the way we eat our food.

Predicting where Australia’s next mineral boom will come from is serious business. Data collected using satellite sensing, airborne surveys, seismic crews and prospecting teams is immense and is piling up rapidly. But what use are all these data?
‘This is a vast electronic resource and we need new methods to mine it for useful information,’ said Professor Dietmar Müller of the University of Sydney.
Professor Müller and his team are developing electronic tools to access and compile the data so that the changes over geological time in the Earth’s crust can be tracked and simulated. Known as the Virtual Geological Observatory (VIRGO), it is one of the new-generation tools Australia will need for future mineral exploration.

We know more about the surface of Mars than we do of the earth beneath our feet. Australian earth scientists are calling for a national program to map our country – 300 metres down under.
By mapping the surface of the continent last century, Australia’s geologists helped to locate the minerals that underpin our economy today. Now most of the surface deposits have been discovered and are being mined. To find more, researchers argue that we need to go deep into the Earth to understand where ore bodies are formed.
