Fluctuations limit sensitive measurements, yet at the same time, noise can unravel properties that are concealed in the averaged signal. I will describe our recent research in this area and introduce several problems in which current noise conveys fundamental information on the transport mechanisms including (i) electronic noise in nanoscale conductors that is generated by temperature differences, (ii) anomalous electronic shot noise, and (iii) cost-precision tradeoff relations (e.g. between output power, power fluctuations and efficiency) in quantum thermoelectric engines and quantum refrigerators.
