The method was used to achieve a 2- to 3-fold increase in production of a protein deficient in patients with Friedreich's ataxia, as described in an article published Instant Online in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com) The article is available free online at the Human Gene Therapy website (http://www.liebertpub.com/hum).
The innovative gene therapy method described by Jacques Tremblay, Pierre Chapdelaine, Zoé Coulombe, and Joel Rousseau, Laval University, Quebec, and University of Quebec, Canada, takes advantage of the ability of a family of proteins called Tal effector (TALE) proteins to target specific DNA sequences. As a model of how this method could be used to treat genetic disease, the authors engineered TALE proteins to target the gene that codes for the frataxin protein, which is deficient in Friedreich's ataxia.
The ability to induce cells to produce more frataxin could reduce symptoms of the disease and provide an effective, long-term therapeutic strategy, conclude the authors in the article "TALE Proteins Induce the Expression of the Frataxin Gene.

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.
