Tasks with high computational requirements, such as tomographic or satellite image reconstruction, combinational problems or computer image recognition would benefit from the high computational capabilities at low price of the hardware devices used in videogame stations or the graphics processing units of personal computers.
This idea culminated in 2003, when Mark Harris, a PhD student at North Carolina University at Chapel Hill (www.unc.edu), now working for the multinational company NVidia, used the computational power offered by a graphics processing unit (GPU) of a personal computer to simulate and render real time images of the physical processes involved in the formation of clouds. Since then, the term GPGPU (General Purpose computing on Graphics Processing Units www.gpgpu.org ) was acquired for the use of graphic processing hardware in more general applications. Currently, this alternative use of the videogame stations and GPUs is being applied in collaborative projects such as Folding@Home (http://folding.stanford.edu).
The present focus of the researchers of the High Performance Computation and Optimization Team (www.gavab.es/capo) part of the GAVAB group (www.gavab.es) at the Rey Juan Carlos University (www.urjc.es) the is project V-ATRAP. The objective of this project is to prove the benefits that this type of technology has to offer as a computing unit for new tasks such as visual recognition and tracing, both very useful applied to real-time video surveillance and offering of up to 14 times faster performances than the existing solution based on the traditional computers.
At present, the technology used in the construction of graphical chipsets for videogame stations is comparable to the most up-to-date technology used by computer manufacturers. In fact, a processing unit of a PC can hold 400 million transistors per core, while an average graphics processing unit can hold as much as double that number. This offers a higher computational power at a lower cost for a wide range of applications, such as high definition video processing, medical image processing or assisted multiple camera video surveillance.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
