James Umen, Ph.D., associate member at Donald Danforth Plant Science Center, and colleagues have discovered a way to make algae better oil producers without sacrificing growth. The findings were published September 6, in a paper titled, “Synergism between inositol polyphosphates and TOR kinase signaling in nutrient sensing, growth control and lipid metabolism in Chlamydomonas,” in The Plant Cell. Umen and his team including lead author Inmaculada Couso, Ph.D., and collaborators Bradley Evans Ph.D., director, Proteomics & Mass Spectrometry and Doug Allen, Ph.D., USDA Research Scientist at the Danforth Center identified a mutation in the green alga Chlamydomonas which substantially removes a constraint that is widely observed in micro-algae where the highest yields of oil can only be obtained from starving cultures.

MIT to neutralize 17 percent of carbon emissions through purchase of solar energy
MIT, Boston Medical Center, and Post Office Square Redevelopment Corporation have formed an alliance to buy electricity from a large new solar power installation, adding carbon-free energy to the grid and demonstrating a partnership model for other organizations in climate-change mitigation efforts.
The agreement will enable the construction of a roughly 650-acre, 60-megawatt solar farm on farmland in North Carolina. Called Summit Farms, the facility, the largest renewable-energy project ever built in the U.S. through an alliance of diverse buyers, is expected to be completed and to begin delivering power into the grid by the end of this year.
Unraveling the Science Behind Biomass Breakdown
Lignocellulosic biomass—plant matter such as cornstalks, straw, and woody plants—is a sustainable source for production of bio-based fuels and chemicals. However, the deconstruction of biomass is one of the most complex processes in bioenergy technologies. Although researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) had already uncovered information about how woody plants and waste biomass can be converted into biofuel more easily, they have now discovered the chemical details behind that process.
Mientras que las emisiones globales de metano han aumentado, estudio dice que los combustibles fósiles no son los culpables
Un nuevo estudio de la NOAA, la National Oceanic Atmospheric Administration, le da un nuevo giro a una espinosa pregunta sobre el impacto del aumento en la producción de petróleo y gas sobre las emisiones de gases de efecto invernadero. Los científicos han detectado un aumento de las tasas de emisiones de metano a nivel mundial desde 2007.
Researchers use 'robomussels' to monitor climate change
Tiny robots have been helping researchers study how climate change affects biodiversity. Developed by Northeastern University scientist Brian Helmuth, the “robomussels” have the shape, size, and color of actual mussels, with miniature built-in sensors that track temperatures inside the mussel beds.
La energÃa renovable goza de un amplio apoyo mientras que los combustibles fósiles dividen la opinión nacional
Una encuesta del Instituto de Investigación PEW llamada "Política del Clima", mostró una bolsa con todo tipo de materiales para los observadores de la industria energética, revelando que una parte de los estadounidenses que apoyan el uso de combustibles fósiles se expandió, mientras que casi todos apoyan las energías renovables.
