New device delivers single cells in just one click

EPFL spin-off SEED Biosciences has developed a pipetting robot that can dispense individual cells one by one. Their innovation allows for enhanced reliability and traceability, and can save life-science researchers time and ...

Followers may tune out when municipalities tweet too much

Municipalities don't need to unleash a tweet storm to keep their citizens informed on the social network Twitter. In fact, according to Penn State researchers, municipalities that tweeted less-frequent, but more focused, ...

Defective software could have doomed Boeing's crew capsule

Defective software could have doomed Boeing's crew capsule during its first test flight, a botched trip that was cut short and never made it to the International Space Station, NASA and company officials said Friday.

Etalumis 'reverses' simulations to reveal new science

Scientists have built simulations to help explain behavior in the real world, including modeling for disease transmission and prevention, autonomous vehicles, climate science, and in the search for the fundamental secrets ...

Hello, world! A new approach for physics in de Sitter space

For decades, physicists have been attempting to reconcile quantum mechanics, the physics of the very small, with gravity, the physics of the very large. While many academics are working on quantum gravity, they often use ...

New tool can pinpoint origins of the gut's bacteria

A UCLA-led research team has developed a faster and more accurate way to determine where the many bacteria that live in, and on, humans come from. Broadly, the tool can deduce the origins of any microbiome, a localized and ...

Computer program

Computer programs (also software programs, or just programs) are instructions for a computer. A computer requires programs to function, typically executing the program's instructions in a central processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled), enables a programmer to study and develop the algorithm.

Computer source code is often written by professional computer programmers. Source code is written in a programming language that usually follows one of two main paradigms: imperative or declarative programming. Source code may be converted into an executable file (sometimes called an executable program or a binary) by a compiler. Alternatively, computer programs may be executed by a central processing unit with the aid of an interpreter, or may be embedded directly into hardware (in which case it is more widely known under the term 'firmware', as something 'between' software and hardware).

Computer programs may be categorized along functional lines: system software and application software. And many computer programs may run simultaneously on a single computer, a process known as multitasking.
