Integrating small-angle neutron scattering with machine learning enhances measurements of complex molecular structures
Small-angle scattering (SAS) is a powerful technique for studying nanoscale samples. So far, however, its use in research has been held back by its inability to operate without some prior knowledge of a sample's chemical composition. Through new rese.....»»
Hubble measures the distance to a supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete......»»
Belle II experiment reports the first direct measurement of tau-to-light-lepton ratio
The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort primarily relies on the.....»»
Hexagonal metallic-mean approximants help bridge gap between quasicrystals and modulated structures
For a long time, scientists associated crystal structures with an ordered arrangement of atoms in a repeating lattice-like pattern, believing it to be the most stable configuration. However, by the 1960s, advancements in crystallography revealed mate.....»»
