Is this cemetery haunted? Probably not, but there could be tiny things moving beyond the grave. The USGS sampled groundwater downhill of Mt. Hope Cemetery in Lansing, Michigan, to find out if materials associated with decomposition and burial processes could affect groundwater quality near a cemetery.

Coral reefs are prone to phase shifts where they quickly transition from coral-dominated to a uniformity of other organisms, typically algae. The Palmyra Atoll National Wildlife Refuge in the Central Pacific is a unique case where a transition from corals to corallimorphs occurred.

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.

It looks like a holiday ornament, but this lovely object is a single-celled freshwater alga from the desmid family, found in the marshes of Florida’s Arthur R. Marshall Loxahatchee National Wildlife Refuge. USGS biologist Barry Rosen photographed it at 200x magnification using ultraviolent light and a fluorescence microscope.

Non-native Cuban treefrogs have established a breeding population in New Orleans, Louisiana, the first such population on the U.S. mainland outside Florida. The treefrogs were discovered at the Audubon Zoo shortly after a shipment of palm trees from Florida were planted in the zoo's elephant enclosure in 2016.

This HiRISE image cutout shows Recurring Slope Lineae in Tivat crater on Mars in enhanced color. The narrow, dark flows descend downhill (towards the upper left). Analysis shows that the flows all end at approximately the same slope, which is similar to the angle of repose for sand.
