Researchers from the University of Texas Medical Branch at Galveston (UTMB) present significant new discoveries on West Nile virus, monkeypox, and yellow fever in four papers in the September issue of Emerging Infectious Diseases, published by the Centers for Disease Control and Prevention. The articles are summarized below, and can be found on the EID web site at http://www.cdc.gov/ncidod/EID/index.htm.
• In “Year-Round West Nile Virus Activity, Gulf Coast Region, Texas and Louisiana,” West Nile authority Dr. Robert Tesh and colleagues from UTMB and the Harris County and Galveston County mosquito control offices present the first hard evidence that West Nile virus continues to circulate during winter along the Texas and Louisiana Gulf Coasts. This finding is important to understanding how the virus spreads when mosquito populations increase in the spring, both on the Gulf Coast and farther north where migrating birds can carry West Nile great distances.
• Tesh and his colleagues describe a possible new model for studying infections by monkeypox, a relative of the deadly smallpox virus, in “Experimental Infection of Ground Squirrels (Spermophilus tridecemlineatus) with Monkeypox Virus.” Although smallpox has been eradicated from the wild and under treaty is preserved only at a high-security CDC lab in Atlanta and a similar center in Russia, biodefense experts fear other samples of the virus may exist that could pose a grave threat to world health if they fell into the wrong hands, especially since smallpox vaccination is no longer common. Monkeypox affects monkeys in much the same way that smallpox affects humans; it can be used as a substitute for smallpox virus in studies that could lead to treatments for its much more dangerous relative. The discovery that it produces a similar disease in ground squirrels and that these rodents can be employed in experiments instead of monkeys should make such work substantially easier.

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.
