Researchers at Brown University have found the anatomical and evolutionary basis behind the fact that some varieties of grass really are greener than others -- or at least why they're able to produce food for themselves via photosynthesis more effectively than their cousins. According to a study in the Proceedings of the National Academy of Sciences, a slight difference in the cellular structure around the veins in blades of grass can make the difference between a grass that is highly efficient and successful and one that just putters along.
We already know that graphene is a wonder-material, so it's no surprise that it has yet another superpower. It is, however, a little bit of a surprise that there are still superpowers left that it isn't yet known to have. A recent study by a team of scientists from the Korea Research Institute of Chemical Technology, and Ewha Womans University, both in South Korea, have found that graphene has potential in increasing the efficiency of artificial photosynthesis. This is probably thanks in part to its ability to generate electricity when struck by light, and the same qualities that make it great for supercapacitors.
