Genetically Engineered Bacteria Compute The Route
US researchers have created "bacterial computers" with the potential to solve complicated mathematics problems. The findings of the research, published in BioMed Central"s open access Journal of Biological Engineering, demonstrate that computing in living cells is feasible, opening the door to a number of applications. The second-generation bacterial computers illustrate the feasibility of extending the approach to other computationally challenging math problems.

Dose Measurement During Prostate Cancer Treatment

A new PTB measuring system offers the possibility of measuring the absorbed dose in the direct environment of the irradiated tumour During radiation therapy, the physicians try to keep the dose in the tumour as high as possible to destroy as many cancer cells as possible. To avoid the damaging of healthy tissue, it is becoming more and more important to check the exact amount of the dose. For this purpose, the Physikalisch-Technische Bundesanstalt (PTB) has developed a measuring system in the case of which the amino acid "alanine", whose radiation transport properties resemble those of human tissue, is used as indicator. When alanine is irradiated, free radicals are formed, whose concentration is measured with the aid of electron spin resonance (ESR). This allows the absorbed dose to be derived. First investigations on a phantom and also on patients have shown that the method is well functioning. Physikalisch-Technische Bundesanstalt (PTB)
