Scientists ponder plant life on extrasolar Earthlike planets

Plants on extrasolar planets resembling Earth could be as black as these eggplants.Washington University biology and chemistry professor Robert Blankenship and his colleagues are seeking clues to life on extrasolar planets by studying various biosignatures found in the light spectrum leaking out to Earth. They are speculating on what kind of photosynthesis might occur on such planets and what the extrasolar plants might look like.

Washington University in St. Louis to invest $55 million in renewable energy research initiative

Washington University in St. Louis is creating a new International Center for Advanced Renewable Energy and Sustainability (I-CARES) to encourage and coordinate university-wide and external collaborative research in the areas of renewable energy and sustainability — including biofuels, CO2 mitigation and coal-related issues. The university will invest more than $55 million in the initiative, according to Chancellor Mark S. Wrighton.

Universities must tackle global energy, environmental woes, says international call to action

Proclaiming that “energy and environmental issues represent the greatest challenges of this century,” Washington University Chancellor Mark S. Wrighton today joined presidents of six other premier research universities in calling for universities worldwide to marshal their resources for a global effort to secure a brighter, sustainable future. Plans for collaborative academic programs involving education, research, university operations, social sciences and policy studies are detailed in a statement issued May 7.

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.

Department of Energy Funds cyanobacteria sequencing project

That’s a lot of power potential from microscopic cyanobacteria (blue-green algae) that capture sunlight and then do a variety of biochemical processes. One potential process, the clean production of ethanol, is a high priority for DOE. Himadri Pakrasi, Ph.D., Washington University Professor of Biology in Arts & Sciences, and Professor of Energy in the School of Engineering and Applied Science, will head a team of biologists at Washington University and elsewhere in the analysis of the genomes of six related strains of Cyanothece bacteria.

Researchers find ways heat-loving microbes release energy

Jan Amend sampling shallow marine vent fluids in 2005 at Ambitle Island, Papua, New Guinea.Curiosity about the microbial world drove Jan Amend, Ph.D., associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, to Vulcano Island, Italy, a shallow hydrothermal Shangri-la near Sicily. There, Amend and his collaborators managed to examine the environment in depth, design a gene probe, and discover new life-which could have some big implications for the origin and presence of life on Earth.

Systems Analysis of Cyanobacterial Physiology in Membrane Biology

In just six months of collaboration, a Department of Energy grand challenge led by Washington University in St. Louis has resulted in the sequencing and annotation of a cyanobacterium that could yield clues to how environmental conditions influence key carbon fixation processes at the gene-mRNA-protein levels in an organism.
