Light Regimes Shape Utilization of Extracellular Organic C and N in a Cyanobacterial Biofilm
Although it is becoming clear that many microbial primary producers can also play a role as organic consumers, we know very little about the metabolic regulation of photoautotroph organic matter consumption.

The Evolution of Titan's Cold South Polar Cloud
Abstract Early during Titan's southern fall, images captured by Cassini's Imaging Science Subsystem revealed the formation of a large cloud above Titan's south pole. Subsequent analysis of Cassini data revealed the cloud contained HCN ice, but the cloud's evolution has not been examined.
