While these gates might look similar to the entry way of a medieval castle, they are actually part of a scientific experiment that will help scientists design more effective fish passage structures for American Shad. Photo by Kevin Mulligan, USGS.

This USGS Rapid Deployment Gauge was installed near Morovis, Puerto Rico, to monitor the Río Grande de Manatí after Hurricane Maria destroyed the permanent streamgage which typically monitors the river. USGS photo.

Hydrogeophysics Laboratory — Storrs, Connecticut. A saltwater tracer was injected into the shallow aquifer at a uranium-contaminated site in Colorado and monitored for 28 days using a combination of geophysical and well-sampling arrays; the sampling array is marked by the white standpipes adjacent to the central injection tank.

Crocodilians are one of the few reptile taxa that exhibit parental care. In alligators, following nest construction, females stay nearby in a guard hole, and are known to defend their nests against predators or other intruders.

This image shows the blue version of sylvatic plague vaccine bait for prairie dogs. 

Prairie dogs in the wild are less likely to succumb to a deadly disease called sylvatic plague after they ingest peanut-butter-flavored bait that contains a vaccine against the disease.

For the first time, high-resolution images show the three-dimensional structure of massive ice deposits on Mars.
