We report on the creation of an array of spin-squeezed ensembles of cesium atoms via Rydberg dressing, a technique that offers optical control over local interactions between neutral atoms. We optimize the coherence of the interactions by a stroboscopic dressing sequence that suppresses super-Poissonian loss. We thereby prepare squeezed states of N=200 atoms with a metrological squeezing parameter ξ^{2}=0.

The purpose of this study was to describe the 100 most widely viewed YouTube videos on the subject of E. coli to determine what consumers are viewing related to the hazards of, and reducing risk of exposure to, bacteria such as E.

Glove changing by food vendors is particularly important when handling paper currency, as bills can carry and transmit microbes from person to person. The purpose of this study was two-fold: (1) To ascertain the extent to which gloves are changed after monetary transactions in food vendors at a major mall in New Jersey; and (2) to document the level of bacterial contamination and the presence of coliform bacteria on paper currency handled by these vendors.

During 495 monetary transactions observed there were only seven glove changes performed by the workers. Eleven of 34 food workers wore no gloves at all while handling money and food.
