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 ...

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 ...

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 ...

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 ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

In a small business, your abilities to make effective decisions, motivate employees and develop a customer-friendly atmosphere are keys to success. Measuring leadership directly often is a challenge, ...
