A schematic representation of the genomic events associated with breast cancer progression, including the occurrence of telomere crisis.
These confocal microscope images highlight regions of chromosomes in cells of a breast duct exhibiting hyperplasia (left) and one exhibiting carcinoma in situ (right).
Telomere crisis is an important early event in the development of breast cancer, and its occurrence can be identified with precision, according to recent findings by a team of scientists at the Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at San Francisco. Their report is now available through advance online publication of Nature Genetics.
Joe Gray, director of Berkeley Lab’s Life Sciences Division and a professor of laboratory medicine and radiation oncology at UCSF, is one of the paper’s lead authors, with Koei Chin and Britt Marie Ljung of UCSF; Carlos Ortiz de Solorzano, Paul Yaswen, and Martha Stampfer of Berkeley Lab; and Stephen J. Lockett from the National Cancer Institute.
In the breast, cells in a milk-collecting duct occasionally proliferate excessively due to development of a regulatory defect. Gray and his colleagues postulate that this results in a lesion called "usual ductal hyperplasia."

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.
