To Make A Better Sensor, Just Add Noise Monday 7th September 2020 Penn State researchers made novel light  sensor based on the 2D compound semiconductor material MoS 2 Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now Penn State researchers have added a small amount of background noise to enhance very weak signals in a light source too dim to sense. In contrast to most sensors, for which noise is a problem that should be suppressed, they found that adding just the right amount of background noise can actually increase a signal too weak for sensing by normal sensors, to a level that can reach detectability. Although their sensor, based on the 2D compound semiconductor MoS 2 , detects light, the same principle can be used to detect other signals, and because it requires very little energy and space compared to conventional sensors, could find wide adaptation in the coming Internet of Things (IoT). IoT will dep...
 Quora: https://www.quora.com/What-are-some-surprising-facts-regarding-covid-19-that-we-are-aware-of-now ...Larry Alenbaugh You got that right about long term effects and even symptoms that lasts for months after Covid. my wife got Covid. She is fine and only had a mild case,but a month after and she continues to have neural symptoms like loss of concentration, brain fog, and changes in taste, specifically bitter tastes like coffee not so much sweet, sour and salty. and it effects the ability to work. How do you work when you get brain fog randomly and she even had trouble driving at night one time when the brain fog hit while she was driving. I hear something one third to one fifth of Covid patients experience this. on a side note I wonder if long term symptoms are new to Covid or just something scientists haven’t discovered yet. For instance for the last 10 years when I have a cold I experience a cough that lasts 4 to 6 months. Doctors had no idea why I get it and I did rese...
