The week in physics: Groundwater health; Marty Baylor

The week in physics: 24–28 March Seismic data provide a deep dive into groundwater health During times of sparse rainfall, many communities rely on pumping from wells to meet their water needs. But do the water reserves recover when the rains return? Johanna L. Miller Q&A: Marty Baylor enhances students' skills and their sense of belonging as physicists The teaching framework she has developed makes students feel at home in physics and prepares them for the workforce. Toni Feder From the vault: April 1968 The emergence of rheology From the days of Newton and Hooke scientists from many fields have contributed to the study of the deformation of materials. But a lack of communication hindered developments until rheology emerged as a formal branch of mechanics.

Laura Fattaruso From the March issue Up-conversion nanoparticles measure medium-sized forces in hard-to-reach places Squeezing the tiny crystals can dramatically change their photophysics. Johanna L.
