A research team at The Hospital for Sick Children (HSC) and the University of Toronto (U of T), led by Dr. Peter Dirks, has identified for the first time a cancer stem cell in both malignant and benign brain tumours. This discovery may change how brain tumours are studied and how this deadly condition is treated in the future. This research is reported in the September 15, 2003 issue of the scientific journal Cancer Research.
"The discovery of a cancer stem cell for brain tumours means that only a small number of cells in a brain tumour have the ability to drive tumour growth. Many current cancer therapies may fail because they do not kill the cancer-sustaining stem cells. We now have to work on designing therapies that will attack these stem cells," said Dr. Peter Dirks, an HSC neurosurgeon and scientist-track investigator in the Developmental Biology Research Program, and an assistant professor of Neurosurgery at U of T.
Brain tumours are the leading cause of cancer mortality in children and remain difficult to cure despite advances in surgery and drug treatments. In adults, most brain tumours are also amongst the most sinister of cancers with formidable resistance to most therapies.

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.
