Using the Aarhus transmission X-ray microscope we have shown that the mitochondria of human spermatozoa can exist in two morphologically distinct states. We have also discovered new structures on the human spermatozoon surface. These structures manifest as clear vesicular bodies associated with specific membrane domains. They can occur around the acrosomal segment, the mid-piece region or at the basal region. Prior to our findings they were not described in the literature, even though they were clearly visible by light microscopy and ubiquitous among populations of sperm from fertile donors. We report on our findings and subsequent endeavours to elucidate the function of these fascinating structures.

    Humic acids (HA) are chemically heterogeneous and structurally ill-defined biopolymers which are able to bind traces of actinides or lanthanides. Due to their dimensions in the colloidal size range they may affect transport of these elements in aquatic systems. Eu(III)- and UO22+-HA aggregates...

    At the ESRF micro-fluorescence, imaging and diffraction (μ-FID) beamline ID 22, a microimaging and tomography setup has been operational for several months. The coherence properties of the high-energy X-ray undulator beam at ID 22 make the setup especially suited for phase-contrast tomography...
