Ancient Proteins Help Unravel a Modern Cancer Drug’s Mechanism

The cancer drug Gleevec is extremely specific, binding and inhibiting only the cancer-causing tyrosine protein kinase Blc-Abl, while not targeting homologous protein kinases found in normal, healthy cells. Researchers at the ALS have uncovered exactly why that is the case, pointing to novel methods of drug discovery.

The Crystallization of PEDOT:PSS Polymeric Electrodes Probed In Situ during Printing

Organic electronics have emerged into a highly interesting field of research with a great variety of applications. P. Müller-Buschbaum and co-workers demonstrate the importance of in situ investigations during the printing process of organic electronics. In situ grazing-incidence wide-angle x-ray scattering is used to follow the crystallization process of highly conductive PEDOT:PSS polymer mixtures. These findings are important for tuning transparent polymeric electrodes for organic electronics. Cover Image by Christoph Hohmann, Nanosystems Initiative Munich (NIM). Article link.
