The Lycurgus Cup Lycurgus, King of the Edoni in Thrace, is ensnared by the nymph Ambrosia in the form of a vine. The famous Roman cup looks green when lit from outsid, but glows pink when lit from the inside. Modern analysis shows the ancient glass contains nanoparticles of a silver-gold alloy that scatters light strongly at a wavelength in the green part of the spectrum. When the cup is lit from inside, however, the green light is absorbed, and we see the remaining light, which is predominantly red, the complementary color to green. Gold nanocages made at Washington University in St. Louis exploit the physical effect that underlies the cup's color change. For high resolution images of the cup, please go to the British Museum site: http://www.britishmuseum.org Play >

Washington University neuroscience doctoral students explain the brain Neuroscience doctoral students from Washington University in St. Louis teamed up with the St. Louis Science Center recently to help St. Louis children and their parents explore the wonders of brain science. The students, all pursuing their P-H-Ds in areas such as neuroscience, psychology or biomedical engineering at Washington University, are part of a specialized neuroscience research training program funded in part by the National Science Foundation. The Cognitive, Computational and Systems Neuroscience Pathway (CCSN) brings together doctoral students from the University's schools of medicine, engineering and arts and sciences for a specialized two-year course of study that combines the latest in neuroscience knowledge from each of the three disciplines, including a heavy emphasis the quantitative analysis necessary to bring brain research to the next level. The CCSN program grant includes a community outreach component that's designed to help graduates become more comfortable communicating the basics of neuroscience research to non-scientific audiences, such as those attending the recent SciFest at the St. Louis Science Center, which took place Oct. 7-11.

Washington University opens Living Learning Center at Tyson Washington University in St. Louis has opened what could be the first "living building" in North America. The Living Learning Center at Tyson Research Center is designed to be a net zero energy and net zero wastewater facility. Certification could come after the building is fully operational for 12 months and has met the Living Building Challenge requirements. Play >
