Whitlockite in mammary microcalcifications is not associated with breast cancer
Microcalcifications, small deposits of calcium-containing minerals that form in breast tissue, are often, but not always, a warning sign of breast cancer. The relationship between microcalcifications and cancer has not been fully understood thus far. Researchers discovered now that the relationship between microcalcifications and tumors seems to be linked to the presence of a particular mineral called whitlockite, which is rich in magnesium and is found in microcalcifications only in the absence of tumors.

Revealing invisible defects in fusion reactor armor
In an exciting collaboration, Nick Phillips, a PSI Fellow at the cSAXS beamline, reveals nanoscale lattice distortions created by invisible defects in fusion reactor armor. This work develops the current understanding of how the smallest, but most prevalent defects, generated during neutron irradiation behave. The novel Bragg ptychographic approach published in Nature Communications paves the way for fast, robust, 3D Bragg ptychography.

Glycation of collagen: Quantifying rates
Collagen is abundant in the connective tissue of human beings, e.g. in tendons, ligament and cornea. Glycation of collagen distorts its structure, renders the extracellular matrix stiff and brittle and at the same time lowers the degradation susceptibility thereby preventing renewal. Based on models and with parameters determined from experimental data, we describe the glycation of type 1 collagen in bovine pericardium derived bio-tissues upon incubation in glucose and ribose. We hope that this contributes to a better quantitative understanding of the effects of diabetes on collagen.
