The ostentatious, sometimes bizarre qualities that improve a creature's chances of finding a mate may also drive the reproductive separation of populations and the evolution of new species, say two Indiana University Bloomington biologists. In the September 2008 issue of Evolution (now online), Armin Moczek and Harald Parzer examine males from four geographically separated populations of the horned beetle species Onthophagus taurus. The beetles have diverged significantly in the size of the male copulatory organ, and natural selection operating on the other end of the animal -- horns atop the beetles' heads -- seems to be driving it.

The National Science Foundation has awarded chemists from Indiana University Bloomington a $2,925,000 grant to study how viruses pull themselves together. Martin F. Jarrold, Bogdan Dragnea, Stephen C. Jacobson, Peter J. Ortoleva, James P. Reilly, and their collaborators at the IU Nanoscience Center and Indiana University's Center for Cell and Virus Theory will study how viruses build themselves up from their components, as well as how structural transitions occur in the assembled viruses.

The Indiana University Research & Technology Corp.'s board of directors has chosen IU Executive Director for Engagement Tony Armstrong as its new president and CEO. Armstrong won't need much time to adjust to the role -- he's helmed the IURTC and its business incubator, the IU Emerging Technologies Center, on an interim basis since early April.

In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this random synchronization.

Indiana University has acquired a 10-ton, 18.8-Tesla magnet that is part of a $2 million, 800-MHz nuclear magnetic resonance spectrometer system. The instrument, which fits snugly into a pit in Simon Hall's basement, will help IU's life scientists expand their study of the large molecules that are fundamental to all life -- and do so at atomic resolution.
