Novel biosensor offers enhanced DNA detection specificity

Researchers have successfully demonstrated a novel biosensor capable of detecting single-stranded DNA oligonucleotides with high specificity without needing external labels. This advancement paves the way for more accessible ...

Mapping noise to improve quantum measurements

One of the biggest challenges in quantum technology and quantum sensing is "noise"–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information.

Electron vortices in graphene detected for the first time

When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide ...

Alerting communities to hyperlocalized urban flooding

As climate change continues to warm the planet, scientists expect natural hazards such as flooding to increase. Urban flooding can be caused by extreme precipitation events, storm surges, or high tides, with dangerous and ...

A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, all sensors need to be calibrated against known standards.
