    The Biology of the Cell and the High Resolution X-Ray Microscope

    The biologist’s dream is to observe cellular structure and content by natural contrast mechanisms and, if possible, to observe variations as a natural consequence of cell function. While the x-ray microscope w...

    The Stony Brook/NSLS Scanning Microscope

    The Stony Brook / NSLS scanning microscope started operation in 1983. It is based on the use of high resolution zone plates to create an x-ray microprobe; the specimen is then scanned through the spot by a pie...

    A pipiscid-like fossil from the Lower Cambrian of south China

    Exceptional fossil preservation is critical to our understanding of early metazoan evolution. A key source of information is the Burgess Shale-type faunas1,2,3,4,5. Fossils from these deposits provide important i...
