Possible relics of lost WWII US bomber, crew found in Italy

An archaeological dig in Sicily has uncovered traces of a lost World War II American heavy bomber shot down in 1943, and possible human remains that could lead to identification of five airmen whose bodies were never recovered.

A new concept for high-performance detectors

When the Department of Energy's SLAC National Accelerator Laboratory turned on the world's first hard X-ray free-electron laser in 2009, it marked the beginning of a new era in science—one where researchers could directly ...

Mysterious clouds could offer new clues on dark matter

The hunt for gravitational waves, ripples in space and time caused by major cosmic cataclysms, could help solve one of the Universe's other burning mysteries—boson clouds and whether they are a leading contender for dark ...

Electrons set the stage for neutrino experiments

Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles' secrets. Now, a team ...

MKID detectors turn out to have 100 times lower noise

Scientists use superconducting detectors (MKIDs) to discern the spectrum of exoplanets from their faint glow. Now, researchers from SRON Netherlands Institute for Space Research and TU Delft have observed 100 times lower ...

Detectors for a new era of ATLAS physics

The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will dramatically increase the rate of collisions in the ATLAS experiment. While offering an opportunity for physicists to explore some of the rarest processes ...

Sensor

A sensor (also called detector) 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-in-glass 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, most sensors are calibrated against known standards.
