Researchers at New Jersey Institute of Technology (NJIT) are putting a 21st century spin on a 19th century technology to make the nations ports and coastal waters safer. Airships -- known today mainly for advertising flyovers at football games -- are the core of a new coastal surveillance system in development for the Missile Defense Agency (MDA) of the U.S. Department of Defense. But the new models will bear little resemblance to their predecessors. These High Altitude Stratospheric Airships (HASAs) will be unmanned, stationary platforms 14 to 16 miles above the ground. At 500 feet long and 150 feet in diameter with a volume of 5 million cubic feet, the HASAs will be 25 times the size of a Goodyear blimp.
The airships will be equipped with an array of cutting-edge equipment for remote sensing, communications, and risk analysis of suspected threats -- and thats where NJIT comes in. The university is partnering with StratCom International LLC to serve as the academic research and development base for the project.
NJITs component of the project is under the direction of Donald H. Sebastian, PhD, vice president of research and development and director of the universitys Homeland Security Technology Center. Sebastian says the project is a natural fit for NJIT. "We have expertise in the whole range of applicable technologies -- terahertz imaging, advanced materials technology for the airship skin, microelectromechanical systems (MEMS), intermodal freight transportation through our transportation centers, wireless telecommunications, and information-assurance systems. Were also an agile university with a strong entrepreneurial character that allows us to respond quickly to an emerging need such as homeland security."

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.
