Coral genomes reveal how populations rebound after environmental catastrophes
Orbicella annularis coral. One of three surviving members of genus Orbicella. Researchers used the newly sequenced genomes of these three species to reconstruct the population histories of these corals, showing that they could recover after environmental catastrophe and expand into new habitats.

New strategy for antidepressant therapies: Increasing the activity of the neurotransmitter GABA in the brains of depressed mice has antidepressant effects
Microscope images of SST+ interneurons from a control brain (left) and a mutant brain with the GABA receptor disabled (right). The cells are stained with fluorescent dyes labeling the GABA receptor (green), an associated scaffolding protein (red), and the cell body (blue). Loss of green and red staining in the mutant indicates the loss of GABA inhibition in these cells, which leads to antidepressant activity. Credit: Lüscher laboratory, Penn State University.
