Micro-swimmer robots could deliver cargo and drugs

  • PDF
TechAndComputer (Aug. 6, 2012) — When you're just a few microns long, swimming can be difficult. At that size scale, the viscosity of water is more like that of honey, and momentum can't be relied upon to maintain forward motion.

Microorganisms, of course, have evolved ways to swim in spite of these challenges, but tiny robots haven't quite caught up. Now a team of researchers at the Georgia Institute of Technology has used complex...

Broadening researcher access to protein simulation

  • PDF
TechAndComputer (Aug. 6, 2012) — Using just an upgraded desktop computer equipped with a relatively inexpensive graphics processing card, a team of computer scientists and biochemists at the University of California, San Diego, has developed advanced GPU accelerated software and demonstrated for the first time that this approach can sample biological events that occur on the millisecond timescale.

Vaporizing Earth in computer simulations to aid search for super-Earths

  • PDF
TechAndComputer (Aug. 2, 2012) — In science fiction novels, evil overlords and hostile aliens often threaten to vaporize Earth. At the beginning of The Hitchhikers Guide to the Galaxy, the officiously bureaucratic aliens called Vogons, authors of the third-worst poetry in the universe, actually follow through on the threat, destroying Earth to make way for a hyperspatial express route.

Data storage: Keeping things in place

  • PDF
TechAndComputer (Aug. 2, 2012) — Fluid dynamics simulations aim to better predict how air circulating in a hard disk drive perturbs the vibrating read/write head.
