On June 23,2000 during the Club monthly meeting, Dr. Zofia Rek presented an interesting lecture about her work experience at Stanford Synchotron Radiation Laboratory where she works since 1980. SSRL is multidisciplinary laboratory funded by Department of Energy and National Institute of Health. Synchrotron radiation is the electromagnetic radiation emitted by electrons along curved trajectory. Most of the experiments are in the X-ray energy range although higher energies in the alfa range can be obtained. Applications are very diversified: X-ray imaging of defects and strains for large crystals for semiconductor wafers to laser windows to study fusion. In biology studies are made to detect and eleminate selenium areas in USA in order to improve the quality of soil. In medicine radiation is used in angiography to detect blockage of heart arteries without invasion of catater and also in studies of osteoporosis. The large part of the lecture was dedicated to protein crytallography as a tool for solving protein structure so important for human genomic project. Zofia also discussed some other works done by SSRL like membrane protein which works as an intelligent guard against cholera toxin and Topoisomerase a protein that is targeted by anti-cancer drugs. There was a very interesting discussion after the lecture and members of the Club had an opportunity to examine numerous models and sampels brought by Zofia.
