It's official: Physics is hard

  • PDF
TechAndComputer (May 8, 2012) — Toby Cubitt, researcher at Universidad Complutense de Madrid, and member of the QUITEMAD Scientific Consortium (R&D Technologies Program, funded by the Madrid Government) together with other colleagues, have conducted scientific research on the difficulty -- from a computational complexity theory perspective -- of addressing some of the challenges of physics.

The work has been published in the journal Physical Review Letters , and Science magazine has also published an article, commenting on this work. Toby Cubitt and his colleagues, Jens Eisert and Michael Wolf, of the Universities of Berlin and Munich respectively, show in this article the difficulty of obtaining the equations that...

Forces among molecules: Tiny but important

  • PDF
TechAndComputer (Mar. 23, 2012) — Forces are not only associated with machines or muscles. You can also find them elsewhere, for instance between molecules. Theoretical chemists like Dr. Łukasz Tomasz Rajchel (University of Warsaw) are familiar with that. However, they -- or rather their computers -- are not capable of calculating them with high accuracy and efficiency at the same time.

The scholarship holder of the Alexander von Humboldt Foundation wants to get to the bottom...

Carbon dioxide catchers: New tools for identifying effective carbon capture technologies

  • PDF
TechAndComputer (Mar. 1, 2012) — Approximately 75 percent of electricity used in the United States is produced by coal-burning power plants that spew carbon dioxide (CO2) into the atmosphere and contribute to global warming. To reduce this effect, many researchers are searching for porous materials to filter out the CO2 generated by these plants before it reaches the atmosphere, a process commonly known as carbon capture. But identifying these materials is easier said than...

Galaxy DNA-analysis software is now available 'in the cloud'

  • PDF
TechAndComputer (Nov. 8, 2011) — Galaxy -- an open-source, web-based platform for data-intensive biomedical and genetic research -- is now available as a "cloud computing" resource.

A team of researchers including Anton Nekrutenko, an associate professor of biochemistry and molecular biology at Penn State University; Kateryna Makova, an associate professor of biology at Penn State; and James Taylor from Emory University, developed the new...

Computational modeling can help plan vaccine introduction, study finds

  • PDF
TechAndComputer (Sep. 29, 2011) — Proper planning before the introduction of new vaccines into a developing country's active immunization program could prevent storage problems and transportation bottlenecks that decrease the availability of existing vaccines by as much as two-thirds, according to a University of Pittsburgh study.

Computational models can assess the evolving needs of the vaccine supply chain -- or the series of steps required to...
