Deconstructing dyes: the colourings used in historical artworks

Date: Feb 12, 2016

Author: Ryan De Vooght-Johnson

Plant extracts have been used as dyes for over 5000 years and are behind some of history’s greatest artworks. In a new study, researchers report a HPLC-based method to identify natural dyes, applied to an ancient Italian carpet.

Blood test could predict prognosis for prostate cancer

Date: Jan 13, 2016

Author: Ryan De Vooght-Johnson

Accurate prostate cancer staging is important for selecting the best treatment, but currently requires biopsy. A study newly published in The Prostate describes markers in blood, measured by LC-MS/MS, which correlate with the stage of the disease and may be useful for predicting prognosis.
