A web-based application that tracks dangerous viruses as they spread has been restructured to allow even wider use of the program around the world. SUPRAMAP, a program that synthesizes large, diverse datasets to help researchers understand the evolution of infectious diseases across hosts and geography, was developed in 2007 by the Museum, The Ohio State University, and the Ohio Superconductor Center. In a recent paper in the journal Cladistics, researchers from these institutions describe how they reconfigured SUPRAMAP’s server to let researchers and public safety officials develop their own applications for the program.
In the late 1960s, Curator Emeritus Niles Eldredge was a graduate student with a passion for trilobite eyes. He had been taught to expect slow and steady change between the specimens of these Devonian arthropods he collected for his dissertation. Only his trilobites were doing one of two things: staying the same, or evolving in leaps.
Museum graduate student Edward Stanley recently used high-resolution x-ray images of tiny “armor” bones to help an international team of scientists discover a new species of lizard from remote, war-torn mountains in Central Africa. The lizard, Cordylus marunguensis, was found on the Marungu Plateau in the southeastern Democratic Republic of the Congo. It is described in the African Journal of Herpetology.
The new lizard was discovered on an expedition led by Eli Greenbaum, assistant professor of evolutionary genetics at the University of Texas at El Paso, and Chifundera Kusamba, a research scientist from the Centre de Recherche en Sciences Naturelles in the Congo. Suspecting that the lizard represented a new species, Greenbaum sent DNA samples and a specimen to Stanley, a third-year student in the Museum’s Richard Gilder Graduate School—the first museum program in the Western Hemisphere with the authority to grant the Ph.D. degree.
Were dinosaurs already undergoing a long-term decline before an asteroid hit at the end of the Cretaceous about 65.5 million years ago? A new study led by Museum scientists gives a multifaceted answer.
