National Institute on Aging (NIA) researchers have discovered a new gene, FANCM, which sheds light on an important pathway involved in the repair of damaged DNA. Specifically, mutation in this gene is responsible for one of the forms of Fanconi anemia (FA), a rare genetic disorder that primarily affects children. Like many rare, inherited diseases, understanding this gene’s role in the development of FA provides insights into other medical problems -- in this case, age-related conditions including ovarian and pancreatic cancers, as well as leukemia, the researchers said. Discovery of this gene and its protein provides a potential target for the development of drugs that can prevent or alleviate FA and a variety of cancers.
The finding is scheduled for advanced online publication in Nature Genetics during the week of August 21, 2005.* The report also will be published in the journal’s September 2005 print edition. The NIA is a component of the National Institutes of Health (NIH) at the U.S. Department of Health and Human Services.
"FA is a disease that appears to be the result of a breakdown in vital DNA repair mechanisms," said Weidong Wang, Ph.D., a senior investigator in the NIA’s Laboratory of Genetics, who led the study. "Some scientists theorize that DNA damage, which gradually accumulates as we age, leads to malfunctioning genes and deteriorating tissues and organs as well as increased risk of cancer. We believe that this new gene, FANCM, may be a potent cog in the DNA repair machinery," Wang said. "It is possible that we could learn how to promote the function of DNA repair complexes and thereby prevent the age-related accumulation of DNA damage."

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.
