An international team of scientists has determined the structure of a protein in its natural environment, the living cell, using nuclear magnetic resonance (NMR) spectroscopy. The method links signals from living cells to specific proteins that have been labeled with the stable nitrogen isotope N-15. But since the cells survive for only 5 to 6 hours without supply of oxygen and nutrients, the scientists used computational reconstruction of the com... More

(Wiley-Blackwell) German researchers led by Horst Weller and Stephan Foerster have produced amphiphilic hybrid particles made of a water-insoluble inorganic nanoparticle at the core surrounded by a bristle-like layer of hydrophilic polymer chains. The polymer-coated spheres offer a simple method for the controlled production of superstructures, such as vesicles to be used to encapsulate drugs or as contrast agents.
