Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess CO2 to store solar energy -- in the form of chemical bonds -- for use when the sun is not shining and in times of peak demand.
Science and Technology
Scientists revived vital functions in the brains of pigs hours after they died; a major breakthrough that could help treat victims of heart attacks and strokes. When humans and large mammals die, the cells responsible of neutral function begin to degrade as result of the blood supply end. Reviving the cells is long considered to be impossible.
