What makes a planet habitable

Which of Earth's features were essential for the origin and sustenance of life? And how do scientists identify those features on other worlds?

Magma is the key to the moon's makeup

For more than a century, scientists have squabbled over how the Earth's moon formed. But researchers at Yale and in Japan say they may have the answer.

Scientists create first billion-atom biomolecular simulation

Researchers at Los Alamos National Laboratory have created the largest simulation to date of an entire gene of DNA, a feat that required one billion atoms to model and will help researchers to better understand and develop ...

To save life on Earth, here's the $100 billion-a-year solution

There have been five mass extinctions in the history of the Earth. But in the 21st century, scientists now estimate that society must urgently come to grips this coming decade to stop the very first human-made biodiversity ...

Record-shattering underwater sound

A team of researchers has produced a record-shattering underwater sound with an intensity that eclipses that of a rocket launch. The intensity was equivalent to directing the electrical power of an entire city onto a single ...

Science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge-base or prescriptive practice that is capable of resulting in a prediction or predictable type of outcome. In this sense, science may refer to a highly skilled technique or practice.

In its more restricted contemporary sense, science refers to a system of acquiring knowledge based on scientific method, and to the organized body of knowledge gained through such research. This article focuses on the more restricted use of the word. Science as discussed in this article is sometimes called experimental science to differentiate it from applied science—the application of scientific research to specific human needs—although the two are often interconnected.

Science is a continuing effort to discover and increase human knowledge and understanding through disciplined research. Using controlled methods, scientists collect observable evidence of natural or social phenomena, record measurable data relating to the observations, and analyze this information to construct theoretical explanations of how things work. The methods of scientific research include the generation of hypotheses about how phenomena work, and experimentation that tests these hypotheses under controlled conditions. Scientists are also expected to publish their information so other scientists can do similar experiments to double-check their conclusions. The results of this process enable better understanding of past events, and better ability to predict future events of the same kind as those that have been tested.
