Single-celled bacterium works 24-7

Researchers at Washington University in St. Louis have gained the first detailed insight into the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green algae) known to cycle between photosynthesis during the day and nitrogen fixation at night.

Protein enables discovery of quantum effect in photosynthesis

Photosynthesis transforms light, carbon dioxide and water into chemical energy in plants and some bacteria.When it comes to studying energy transfer in photosynthesis, it’s good to think “outside the bun.” That’s what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein that he calls the taco shell protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protein enabled the surprising discovery of a quantum effect in photosynthesis.

Cell splits water via sunlight to produce hydrogen

David Kilper/WUSTL PhotoPratim Biswas and his group have developed a method to make a variety of oxide semiconductors that, when put into water promote chemical reactions that split water into hydrogen and oxygen.Engineers at Washington University in St. Louis have developed a unique photocatalytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties.

Cell splits water to produce hydrogen via sunlight

WUSTL engineers have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The technique will be demonstrated at a poster session May 6, 2007, at the International Symposium on Energy and Environment, held at the University.
