Recreating a slice of the universe: Computational approach follows thousands of galaxies over billions of years

  • PDF
TechAndComputer (Aug. 15, 2012) — Scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and their colleagues at the Heidelberg Institute for Theoretical Studies (HITS) have invented a new computational approach that can accurately follow the birth and evolution of thousands of galaxies over billions of years. For the first time it is now possible to build a universe from scratch that brims with galaxies like we observe around us.

Wind farms: A danger to ultra-light aircraft?

  • PDF
TechAndComputer (Aug. 13, 2012) — Airfields for ultra-light aircraft are typically constructed on level ground -- and so are wind farms. However, do wind power plants generate turbulence that could endanger lightweight planes? A simulation can compute how these power plants influence aircraft at various wind speeds and wind directions.

Molecular economics: New computer models calculate systems-wide costs of gene expression

  • PDF
TechAndComputer (Aug. 7, 2012) — Bioengineers at the University of California, San Diego have developed a method of modeling, simultaneously, an organism's metabolism and its underlying gene expression. In the emerging field of systems biology, scientists model cellular behavior in order to understand how processes such as metabolism and gene expression relate to one another and bring about certain characteristics in the larger organism.
