Aliquots – VUMC research highlights

Jan. 6, 2011—RSV prefers stressed cells “Stress granules” – globs of proteins and RNAs – form inside cells in response to environmental stressors and are thought to regulate protein production. Several viruses induce stress granule formation, but the function of these structures during virus replication is not well understood. James Crowe Jr., M.D., and colleagues report that...

TIPSHEET: The future of Pluto and Ceres

Dec. 21, 2009—Three years ago, when the International Astronomical Union demoted Pluto to dwarf planet status, the unpopular decision was based on personal opinions and professional politics, not on rigorous scientific criteria that can clearly differentiate planets from lesser bodies, points out Vanderbilt astronomer David Weintraub. In the next decade, however, the amount of knowledge that we have about Pluto and another dwarf planet, Ceres, will change dramatically and this new information may affect our views of these objects and their status in the solar system as asteroids, dwarf planets or planets.

Nuclear energy powered by uranium from the sea could promote peace in coming century

Dec. 18, 2009—One of the best things the world can do to promote peace and stability in the coming century is to expand commercial nuclear power based on the extraction of uranium from the ocean. That is the proposition which Frank Parker, an internationally recognized expert in remediation of radioactively contaminated soil and water and a member of the National Academy of Engineering, advanced at an exclusive meeting held at the Pontifical Academy of Sciences in the Vatican last month.

New study confirms exotic electric properties of graphene

Nov. 17, 2009—First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.

Interdisciplinary research team to develop novel drug detection technology using software that acts like a robotic scientist

Nov. 9, 2009—With the support of a $2.7 million Recovery Act grant from the National Institute of Drug Abuse (NIDA), an interdisciplinary team headed by Vanderbilt chemist John McLean and physicist John Wikswo will attempt to determine whether an individual's white blood cells retain chemical memories of exposure to drugs like cocaine and alcohol that can be read reliably and unambiguously.
