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.
Scientists in Germany have uncovered a new species of flying dinosaur; a discovery that could help understand how modern-day birds evolved, said a new study published in the journal Life Sciences. Another feathered species of dinosaur, that lived around 150 million years ago, was previously discovered in 1861. The species, called Archaeopteryx, was widely considered to be the oldest flying bird.
