Researchers at Jefferson Medical College and at the Wadsworth Center in New York have identified a gene defect in mice resulting in a range of abnormalities, from cyclical hair loss and skin cancer to severe problems in normal skin development. The work may lead to improved treatments for skin injuries, including burns, and might have implications for diseases such as eczema and psoriasis, as well as certain cancers.
Linda Siracusa, Ph.D., associate professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University in Philadelphia and at Jeffersons Kimmel Cancer Center and Bruce Herron, Ph.D., a research scientist at the Wadsworth Center of the New York State Department of Health and assistant professor in the Department of Biomedical Sciences at the State University of New York at Albany, wanted to identify the nature of an inherited genetic mutation in mice called repeated epilation (Er), and pinpoint the gene itself.
Mice carrying one copy of the mutation have cyclical hair loss, and develop skin cancer late in life. Mice carrying two copies have severe defects in skin development related to keratinocyte (skin cell) differentiation. At birth, they lack external openings – the nose and mouth are covered by skin, for example – and live only a brief 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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
