Another step toward creating brain-reading technology

A team of researchers at the University of California's Department of Neurological Surgery and the Center for Integrative Neuroscience in San Francisco has taken another step toward the development of a device able to read ...


How chronic inflammation may drive down dopamine and motivation

Growing evidence shows that the brain's dopamine system, which drives motivation, is directly affected by chronic, low-grade inflammation. A new paper proposes that this connection between dopamine, effort and the inflammatory ...

Gold makes invisible surfaces visible in CT

Today, the three-dimensional visualization and analysis of biological samples using computer tomography (CT) is a routine procedure. However, in the past, it was very difficult to visualize the fine surface details of many ...


'DeepSqueak' helps researchers decode rodent chatter

Many researchers realize that mice and rats are social and chatty. They spend all day talking to each other, but what are they really saying? Not only are many rodent vocalizations unable to be heard by humans, but also existing ...

Computer science

Computer science (or computing science) is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that describe and transform information. According to Peter J. Denning, the fundamental question underlying computer science is, "What can be (efficiently) automated?" Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing computations, while computer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to people.

The general public sometimes confuses computer science with vocational areas that deal with computers (such as information technology), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones.
