Ionizing radiations play a vital role in the treatment and diagnosis of malignant neoplastic illnesses as well as in the diagnosis of other pathologies. However, according to Manuel Vilches Pacheco from the Medical Physics and Radiology Department at the Hospital Virgen de las Nieves in Granada, “the potential harm ionizing radiations can cause means that, in order to obtain clinical benefits and reduce the onset of unwanted adverse effects as much as possible, they must be used under strict quality control”.
According to experts, this is why it is important to develop instruments which can verify the final result by carrying out a direct follow-up of treatments administered to patients, such as image registration (portal imaging system) or the in vivo measurement of the exact dose administered to patients.In vivo Control
On this matter, Alberto Palma López, from the Department of Electronics and Computer Science at the University of Granada, explains that this new device does not require an electricity connection or a reading supply unit and, among other improvements, it minimizes treatment disorders and is made of low-cost and reusable electronic devices, “something that was impossible until now”.
Furthermore, the device’s design has metrological characteristics which ensures that it performs correctly at high temperatures. This means the room does not need to be specially fit out. The detector’s minuscule size can measure the radiation quickly in different areas of the body as well as keep a historical record of the patient.
Significant progress has been made in encouraging the widespread use in vivo dosimetry control, an important element among patients undergoing radiotherapy. However, its use can be extended to other radiological practices such as diagnosis by X-ray or for the protection of professionals exposed to a radioactive environment.
Today, the Oficina de Transferencia de Resultados de Investigación (OTRI), from the University of Granada, promotes this device wich is protected by patent.

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.
