New research shows live chats can increase sales by nearly 16%

Live chat tools allow for communication between sellers and buyers. They are popular instruments for e-commerce sites that don't have the advantage of face-to-face communication that brick-and-mortar stores do. New research ...

Computing with molecules: A big step in molecular spintronics

Spintronics or spin electronics in contrast to conventional electronics uses the spin of electrons for sensing, information storage, transport, and processing. Potential advantages are nonvolatility, increased data processing ...

Black hole nurtures baby stars a million light years away

Black holes are famous for ripping objects apart, including stars. But now, astronomers have uncovered a black hole that may have sparked the births of stars over a mind-boggling distance, and across multiple galaxies.

Study shows evolution turns genes back on to regain function

Genes often mutate and lose their natural or synthetic function over long-term evolution, which could be good if that stops drug resistance of infectious microbes or cancer. A new study by Stony Brook University researchers, ...

New insights could help tame speedy ions in fusion plasmas

To create a practical fusion energy reactor, researchers need to control particles known as fast ions. These speedy ions, which are electrically charged hydrogen atoms, provide much of the self-heating ability of the reactor ...

A reliable clock for your microbiome

For all the attention the human microbiome has been getting over the last few years, one aspect of such research rarely makes headlines: the difficulty of observing how it changes over time in response to various stimuli. ...

Researchers use laser light to transform metal into magnet

Pioneering physicists from the University of Copenhagen and Nanyang Technological University in Singapore have discovered a way to get non-magnetic materials to make themselves magnetic by way of laser light. The phenomenon ...

'Fire inversions' lock smoke in valleys

Smoke from a summer wildfire is more than just an eye-stinging plume of nuisance. It's a poison to the lungs and hearts of the people who breathe it in and a dense blanket that hampers firefighting operations.

Feedback

Feedback describes the situation when output from (or information about the result of) an event or phenomenon in the past will influence an occurrence or occurrences of the same (i.e. same defined) event / phenomenon (or the continuation / development of the original phenomenon) in the present or future. When an event is part of a chain of cause-and-effect that forms a circuit or loop, then the event is said to "feed back" into itself.

Feedback is also a synonym for:
