[Cover illustration] Cover illustration: Volume rendering of inline phase-contrast tomography data showing the head of a mosquito (genus Anopheles). The phase reconstruction of this data set was performed using the single-distance phase-retrieval computer program ANKAphase (see Weitkamp, Haas, Wegrzynek and Rack, pages 617-629). Three-dimensional images of this kind allow biologists to study morphological differences between individual animals or different species.

Hard X-ray Fourier transform holography from an array of oriented referenced objects

H. Iwamoto and N. Yagi

Synopsis: The use of multiple, oriented and singly referenced objects was evaluated as a means to overcome the low scattering cross section inherent in hard X-ray Fourier transform holography. It is shown that the image of each object can be restored as in the conventional single-object case.

Radiation-induced melting in coherent X-ray diffractive imaging at the nanoscale

O. Ponomarenko, A. Y. Nikulin, H. O. Moser, P. Yang and O. Sakata

Synopsis: Coherent X-ray diffraction techniques play an increasingly significant role in imaging nanoscale structures which range from metallic and semiconductor samples to biological objects. The conventional knowledge about radiation damage effects caused by ever higher brilliance X-ray sources has to be critically revised while studying nanostructured materials.

T. Weitkamp, D. Haas, D. Wegrzynek and A. Rack

Synopsis: ANKAphase is a computer program that processes X-ray inline phase-contrast radiographs by reconstructing the projected thickness of the objects imaged. The program uses a single-distance non-iterative phase-retrieval algorithm described in a paper by Paganin et al. [(2002), J. Microsc. 206, 33-40].

DNA damage and repair kinetics after microbeam radiation therapy emulation in living cells using monoenergetic synchrotron X-ray microbeams

C. N. Sprung, M. Cholewa, N. Usami, K. Kobayashi and J. C. Crosbie

Synopsis: The molecular response of mammalian cells to a monoenergetic synchrotron X-ray microbeam which emulated microbeam radiation configurations has been investigated. Very few [gamma]H2AX foci were found outside the irradiated zone within 1 h of irradiation, even within a single nucleus. Furthermore, 12 h after radiation there was a large decrease in foci number but many cells still contained [gamma]H2AX foci, of which many were outside the directly irradiated regions.
