Scientists looked at multiple techniques used to measure the modified viruses deployed in some gene therapy research and treatments. One technique, known as SEC-MALS, was the most precise and accurate ...

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 ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

A team of scientists devised a new technique for estimating distances to pulsars, challenging traditional methods. By analyzing radio wave effects, the method offers more accurate measurements and ...

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.

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 ...

Compared with research office systolic BP measurement, the pooled mean differences from corresponding systolic BPs were higher for convenient office BP measurement and lower for automated office ...

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 meth ...
