Second year PhD student Courtney Swink was awarded a NSF Graduate Research Fellowship Program Fellowship. Her selection as an NSF Graduate Fellowship awardee is a significant accomplishment and was based on her demonstrated potential to contribute to strengthening the vitality of the U.S. science and engineering enterprise. Courtney is researching […]

Bioenergy Carbon Capture and Storage (BECCS) has been proposed to reduce atmospheric CO2 concentrations, but concerns remain about competition for arable land and freshwater. The synergistic integration of algae production, which does not require arable land or freshwater, with BECCS (called “ABECCS”) can reduce CO2 emissions without competing with agriculture. […]
Happy holidays from the Johnson Lab! Hope plankton brings you something good this year. (Plankton converts to coal in ~300 million years.)
Johnson announced a Sustaining Fellow of the Association for the Sciences of Limnology and Oceanography (ASLO). ASLO Sustaining Fellows are recognized as having sustained excellence in their contributions to ASLO and the aquatic sciences.
Microbial science at Duke is taking a major step forward with the launch of the Duke Microbiome Center (DMC), which is intended to address growing scientific interest in the roles microbial communities play in human health, the environment and biotechnology. The new center expands on the mission of the five-year-old […]
Marine aggregates play a critical role in the biological pump, both as a dominant component of carbon flux and as hotspots for organic matter remineralization by microbial communities. In this study, we used laboratory experiments to investigate how aggregate thin layers, such as those commonly found in the coastal ocean, […]
Prochlorococcus, the smallest and most abundant phytoplankter in the ocean, is highly sensitive to hydrogen peroxide (HOOH), and co-occurring heterotrophs such as Alteromonas facilitate the growth of Prochlorococcus by scavenging HOOH. Temperature is also a major influence on Prochlorococcus abundance and distribution in the ocean, and studies in other photosynthetic […]
Associate Professor Zackary Johnson presented on the trends and patterns of coastal and ocean acidification in coastal North Carolina at the Southeastern Ocean and Coastal Acidification Network NC Stakeholder meeting. The presentation was titled, ‘Variability of the carbonate system (including acidity) in a dynamic coastal NC system’. Ocean and coastal […]
Dr. Zhiying “Bruce” Lu joined the Johnson Lab as a postdoctoral research associate and funded by the China Research Council. Dr. Lu’s research focuses on using recycled medium (used water) for growing microalgae as a source of food and fuel. At the Johnson Lab he will work as part of […]
