ver nitrate and other substances to make the boats' surfaces superhydrophobic. When compared to similar copper boats made without the novel surfaces, the water repellant boats floated more smoothly and also showed a surprisingly large loading capacity. The best performing mini-boat floated with up to two times its maximum projected loading-capacity, the scientists say. "Interestingly, the boat is able to keep floating even if its upper edges are below the water surface," the scientists note. - MTS

First discovery of "animals-only" pigment bilirubin in plants
Journal of the American Chemical Society

In a first-of-its-kind discovery that overturns conventional wisdom, scientists in Florida are reporting that certain plants including the exotic "White Bird of Paradise Tree" make bilirubin. Until now, scientists thought that pigment existed only in animals. The finding may change scientific understanding of how the ability to make bilirubin evolved, they say in a report in the Journal of the American Chemical Society, a weekly publication.

In the new study, Cary Pirone and colleagues note that bilirubin is a brownish yellow substance resulting from the liver's breakdown of hemoglobin, the red pigment that carries oxygen in the blood. Parents know bilirubin as the stuff that discolors the skin of newbo
