Results published in May 6 Issue of Nature
It has taken more than 50 years to accumulate the current body of knowledge on Escherichia coli, a bacterium which is one of the best studied organisms in biology. Now, bioengineers at the University of California San Diego have integrated this knowledge into the first genome-scale model of the gene regulatory system in E. coli. The computational model helps to define the rules governing cell function and quickly enabled an exponential increase in the understanding of the regulatory system in E. coli. Their work, which is published in the May 6, 2004 issue of Nature, represents a new way to systematically drive biological discovery.
"This research is evidence of how much more quickly biological discovery is going to progress now, given that we have high-throughput experimental tools for gathering large volumes of data, and the use of these tools can be guided by computer models," said Bernhard Palsson, professor of bioengineering at the UCSD Jacobs School of Engineering. Palsson co-authored the study with his UCSD bioengineering student Markus Covert, who is now a post-doctoral researcher at the California Institute of Technology.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
