Kīlauea's Kamokuna ocean entry reaches its 1-year anniv.
Kīlauea Volcano's Kamokuna ocean entry photographed on May 23, 2017 (left) and July 13, 2017 (right) show how lava flowing from the tube has both widened and thickened the delta. Near the sea cliff, the delta appears to have doubled in thickness over the past seven weeks, creating a distinctly sloped surface from the base of the cliff to the sea.

In fresh water, these red cyanobacteria don't absorb a green stain
This is the first of two microscopic images of potentially toxic cyanobacteria, Microcystis aeruginosa. In both images, the cyanobacteria have been exposed to a green stain.
Image 1: Microcystis aeruginosa in freshwater. The green stain doesn’t enter the cells, which show up in red.
