The global spread of Highly Pathogenic Avian Influenza (HPAI), particularly the H5N1 2.3.4.4b clade, underscores the urgent ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

Holding pattern Small clusters of caesium atoms (pink blobs) were held in a vertical optical lattice. A laser then splits each atom into a quantum state in which half of the atom was closer to a ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

Flow cytometry is an incredibly useful analytical tool that has revolutionized the way in which single-cell and particle characterization is performed. Despite its effectiveness, flow cytometry ...
