 E-Mail Photosynthetic organisms tap light for fuel, but sometimes there's too much of a good thing. New research from Washington University in St. Louis reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae -- including key features that both collect energy and block excess light absorption. The study, published Jan. 6 in Science Advances, yields insights relevant to future energy applications. Scientists built a model of the large protein complex called phycobilisome that collects and transmits light energy. Phycobilisomes allow cyanobacteria to t...

 E-Mail IMAGE: Researchers have found a new way to predict the properties of metal alloys based on reactions at the boundaries between the crystalline grains of the primary metal. In this image,... view more  Credit: Image courtesy of the researchers Advanced metal alloys are essential in key parts of modern life, from cars to satellites, from construction materials to electronics. But creating new alloys for specific uses, with optimized strength, hardness, corrosion resistance, conductivity, and so on, has been limited by researchers' fuzzy understanding of what happens at the bou...
