Scientists expose vulnerabilities of critical Antarctic ice shelf

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey ...

Urban overheating risks are personal, study finds

Global warming and urbanization are expected to increase heat hazards in cities around the world, but higher temperatures may not always lead to higher health risks, according to a new study in Earth's Future.

The energy transition needs to be climate-proofed

Record-breaking weather events are becoming more common, costly, and extreme. Not only do these extreme weather events destroy lives and homes. Less talked about is how they can also disrupt the deployment of renewable energy ...

Master equation to boost quantum technologies

As the size of modern technology shrinks down to the nanoscale, weird quantum effects—such as quantum tunneling, superposition, and entanglement—become prominent. This opens the door to a new era of quantum technologies, ...

How bat brains listen for incoming signals during echolocation

Neuroscientists at Goethe University, Frankfurt have discovered a feedback loop that modulates the receptivity of the auditory cortex to incoming acoustic signals when bats emit echolocation calls. In a study published in ...

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:
