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 ...

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.

Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various ...

Thin films are two-dimensional (2D) material layers deposited on a bulk substrate, possessing a thickness of a few nanometers to impart properties that cannot be realized by base materials. The unique ...

The energy transition requires not only the development of new technologies, but also their reliable and economical operation. For many years, the Institute of Solar Research has been developing ...

Mechanical forces generated by cells not only drive the bending, stretching, alignment, and repositioning required for tissue development and homeostasis, but also regulate cell functions ranging from ...

Large contractors are putting a new standard for productivity measurement to the test in the hope of producing better project process controls. The new standard, which was adopted last fall as ASTM ...
