TL;DR: X-ray fluorescence microscopy of VC uptake by murine colon cancer is reported, the first direct demonstration that VCs selectively accumulate in cancer cells, and thus may improve cancer detection.

TL;DR: In this paper , the authors show that high-speed ptychographic data acquisition with short exposure can effectively reduce the impact from experimental variations, and further demonstrate that a continuous multi-pass scan via high speed Ptychography can achieve high-resolution imaging.

TL;DR: In this paper, an instrument development project aimed at developing an X-ray spectrometer configuration for the Xray fluorescence microprobe optimized for the detection of precious metals in geological and biological samples is presented.

TL;DR: The worldwide march to electron storage rings with diffraction-limited photon properties in the X-ray regime is well underway as discussed by the authors, with MAX-IV in Sweden, scheduled for operation in 2016, followed by SIRIUS in Brazil in 2018; both are greenfield rings operating at 3 GeV with ~520 m circumference and emittances of ~250 pm-rad.
