How NASA Earth data aids America, state by state

For six decades, NASA has used the vantage point of space to better understand our home planet and improve lives. A new interactive website called Space for U.S. highlights some of the many ways that NASA's Earth observations ...

Researcher uses network science to understand how materials work

Network science is how mathematicians and software designers construct complicated social networks like Facebook. But a group of Florida State University researchers has found that these equations can tell engineers a lot ...

Multistep self-assembly opens door to new reconfigurable materials

Self-assembling synthetic materials come together when tiny, uniform building blocks interact and form a structure. However, nature lets materials like proteins of varying size and shape assemble, allowing for complex architectures ...

Neuron and synapse-mimetic spintronics devices developed

A research group from Tohoku University has developed spintronics devices which are promising for future energy-efficient and adoptive computing systems, as they behave like neurons and synapses in the human brain.

Parboiling method reduces inorganic arsenic in rice

Contamination of rice with arsenic is a major problem in some regions of the world with high rice consumption. Now, researchers reporting in the ACS journal Environmental Science & Technology have found a way to reduce inorganic ...

Carriers deliver controllable cancer chemotherapy

Cancer kills more than half a million men, women, and children each year in the U.S, and chemotherapy is only slightly more discriminating than the disease it treats. As a result, many cancer treatments kill cells throughout ...

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.
