[ Watch The Video: Capturing the Carboxysome in Motion ] DOE/Joint Genome Institute Cyanobacteria, found in just about every ecosystem on Earth, are one of the few bacteria that can create their own energy through photosynthesis and "fix" carbon – from carbon dioxide molecules – and convert it into fuel inside of miniscule compartments called carboxysomes. Using a pioneering visualization method, researchers from the University of California, Berkeley and the Department of Energy...

Max Planck scientists discover photosynthesis helper protein in red algae Photosynthesis is one of the most important biological processes. However, it is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now identified a so far unknown helper protein for photosynthesis in red algae. “We could...

Knowledge could improve microorganism as a renewable energy source A new computer model of blue-green algae can predict which of the organism's genes are central to capturing energy from sunlight and other critical processes. Described in a paper published in the journal Molecular BioSystems, the model could advance efforts to produce biofuel and other energy sources from blue-green algae, known as cyanobacteria. Researchers from the Department of Energy's Pacific Northwest National...

"I have a slide that has a photo of a cornfield and a big photovoltaic array," says Robert Blankenship, a scientist who studies photosynthesis at Washington University in St. Louis. "When I give talks I often ask the audience which one is more efficient. Invariably the audience votes overwhelmingly in favor of photosynthesis. " They are wrong. This question and its surprising answer (below) is the point of departure for a provocative article published in the May 13 issue of Science. The...

Study raises concerns for agriculture In August of 2008 Jacob Schaefer, PhD, on vacation in San Diego, picked up a copy of the Los Angeles Times. As it happened, the newspaper was running a series on the wildfires in the western United States. The wildfires, he read, are more frequent "” they now occur every few years instead of every few decades "” and they are burning larger areas. The more intense fire cycle is fueled by cheatgrass (Bromus tectorum), an invasive plant that is...

By Lapointe, Mathieu MacKenzie, Tyler D B; Morse, David The oceans globally constitute an important sink for carbon dioxide (CO2) due to phytoplankton photosynthesis. However, the marine environment imposes serious restraints to carbon fixation. First, the equilibrium between CO2 and bicarbonate (HCO^sub 3^-) is pH dependent, and, in normal, slightly alkaline seawater, [CO2] is typically low (approximately 10 mM ). Second, the rate of CO2 diffusion in seawater is slow, so, for any cells...
