Journal Highlight: Expanding the data depth for the analysis of complex crude oil samples by FTICR MS using the spectral stitching method
Date: May 10, 2012
Author: spectroscopyNOW
Spectral stitching using small SIM windows was used to overcome the suppression effects observed with crude oil samples in FTICR MS caused by the sheer number of individual compounds present.

It takes an age: Art pigments influence degradation of protein-based binders under UV light
Date: Apr 15, 2012
Author: Steve Down
The ageing of protein-based binders in works of art by UV light is affected by the presence of pigments, say European scientists, who followed the changes in rabbit glue. The findings should be useful in the fields of restoration and conservation.

Journal Highlight: Finding the right balance - a personal journey from individual proteins to membrane-embedded motors
Date: Apr 9, 2012
Author:
The present review, based on the FEBS/EMBO Women in Science Lecture, offers a personal view of the transition from determining the mass of an individual protein to elucidating the structure and dynamics of heterogeneous assemblies in the megadalton mass range.
