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 ...

Scientists from the University of Illinois at Urbana-Champaign and the University of Chicago have proposed a new way to refine the Hubble constant using gravitational waves. The method can help solve ...

A new tissue expansion method enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. For biologists, ...

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 ...
