Astrophysicists propose a new “stochastic siren” method using the gravitational-wave background from black hole mergers to ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

VTT has developed an immunocomplex antibody-based method that is suitable for the precise and rapid detection of small molecules.

Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent study has calibrated the best cosmic yardsticks to ...

The fragility and laws of quantum physics generally make the characterisation of quantum systems time-consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A ...

Mobility Components (PEM) at RWTH Aachen University, in collaboration with industry partner Suragus, is researching a ...

La Trobe University researchers have developed a new way to measure and report the environmental performance of farms in a move that could pave the way for future "sustainability ratings" on consumer ...
