A USGS scientist prepares a sample to test the effect of antibiotics
A USGS scientist prepares a sample to test the effect of antibiotics on denitrifying bacteria within a glove box. A glove box allows scientists to work with samples in an anaerobic (no oxygen) atmosphere, the conditions under which denitrification occurs.

Using the 384-well plate format, a single zebrafish embryo is tested
Using the 384-well plate format, a single zebrafish embryo is tested in each well. This is an example of a 72 hour post fertilization fli1:egfp zebrafish (3 millimeters long) imaged under a fluorescein isothiocyanate (FITC) filter.

Otolith from a Bloater Chub used for age analysis
An otolith, sometimes called “earstone,” of a bloater, a small prey fish in the Great Lakes. Fishery scientists interpret the age of bloater and other fishes by counting annual growth rings on their otoliths.
