MicroFPGA: An affordable FPGA platform for microscope control.

Modern microscopy relies increasingly on microscope automation to improve throughput, ensure reproducibility or observe rare events. Automation requires computer control of the important elements of the microscope. Furthermore, optical elements that are usually fixed or manually movable can be placed on electronically-controllable elements.

[Dramatic changes in the age structure for medical specialists in the field of mental health].

Background: Over the past 20 years the importance of treatment of people with mental and neurological disorders has greatly increased. Parallel to this development it has become more difficult to attract young physicians to this field. The aim of this study was to examine the development of the number of physicians specialized in the care of patients suffering from neurological, mental and psychosomatic disorders with special consideration of the age structure.

[The State of Application of Clinical Ethics Consultation in German Psychiatric Hospitals].

This study provides for the first time a comprehensive overview of the state-of-the-practice of clinical ethics consultation in German psychiatric hospitals. Structures for ethics counselling were available in only 57 % of the hospitals. In about one third of the participating hospitals, structures of ethics counselling had not yet been considered or were actively dismissed.

Anomalous signal from S atoms in protein crystallographic data from an X-ray free-electron laser.

X-ray free-electron lasers (FELs) enable crystallographic data collection using extremely bright femtosecond pulses from microscopic crystals beyond the limitations of conventional radiation damage. This diffraction-before-destruction approach requires a new crystal for each FEL shot and, since the crystals cannot be rotated during the X-ray pulse, data collection requires averaging over many different crystals and a Monte Carlo integration of the diffraction intensities, making the accurate determination of structure factors challenging. To investigate whether sufficient accuracy can be attained for the measurement of anomalous signal, a large data set was collected from lysozyme microcrystals at the newly established `multi-purpose spectroscopy/imaging instrument' of the SPring-8 Ångstrom Compact Free-Electron Laser (SACLA) at RIKEN Harima.
