Prostate cancer patients with high risk cancers who are treated with both internal and external radiation and hormone treatment have a better chance of beating the disease than patients treated with radiation alone, according to a new study published in the January 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.
Since the late 1980s, doctors have been increasingly using internal radiation, also called radioactive seed implants or brachytherapy, to cure prostate cancer. For patients with higher risk prostate cancers – defined as having at least two of the following three: a high Gleason score, a high PSA score and/or an advanced stage – doctors have been adding hormone therapy and external beam radiation therapy to the treatment plan to try to increase survival rates. In this study, doctors studied nearly 200 men with high risk prostate cancer over eight years to see if adding external beam radiation and hormone therapy to brachytherapy did indeed increase disease-free survival rates.
Of the participating patients, 107 men were treated with external beam radiation therapy combined with seed implants. Another 69 patients received hormone therapy in addition to the seed implants and external beam radiation. After eight years, nearly 94 percent of the men who had hormone therapy in addition to the two types of radiation had no evidence of their prostate cancer, compared with 84 percent of the men who only had seed implants and external beam radiation therapy.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
