Journal Highlight: Chemometric brand differentiation of commercial spices using direct analysis in real time mass spectrometry

Date: May 16, 2016

Author: spectroscopyNOW

Chemometric models were able to classify the DART mass spectra of commercial cinnamon samples according to brand using a method that could be generalized to other classes of spices and applied to examining evidence from improvised explosives.

Decompression sickness: Protein biomarkers

Date: May 15, 2016

Author: Steve Down

The onset of decompression sickness in rats leads to a change in the proteome, highlighting proteins which could act as biomarkers of the condition as well as shedding light on the physiological mechanism at play.

Sweat diffusion through snow: Canines and trapped humans

Date: May 15, 2016

Author: Steve Down

A GC/MS method with direct immersion SPME has been developed for measuring the diffusion dynamics of human sweat compounds buried under snow, which will help to understand the success rate of search and rescue dogs combing avalanches for victims.

The metabolome of the bellyache bush

Date: May 15, 2016

Author: Ryan De Vooght-Johnson

Metabolites are small molecules that define species, yet there is still no efficient and reproducible way of analysing them. A new paper in the Journal of Separation Science might provide such a method: a sequential strategy for extracting and separating metabolites, applied to the Brazilian bellyache bush.

AFM rules: Supports spectroscopic insights

Date: May 15, 2016

Author: David Bradley

Non-contact atomic force microscopy has been used to investigate simple chemical reactions at atomic resolution confirming what chemists knew from spectroscopy. The research offers new rules for predicting the properties of catalytic reactions and for designing novel catalysts.

X-rays help outwit superbugs: Mercy MRSA

Date: May 15, 2016

Author: David Bradley

Small angle X-ray scattering (SAXS) and X-ray diffraction have been used to characterize one of the key metabolic enzymes in a so-called superbug, which could open up a new target for antibiotic-resistant bacteria.

It's a stitchup: Evolving new proteins

Date: May 15, 2016

Author: David Bradley

Scientists in the USA are stitching together novel proteins from fragments in an evolutionary manner and using nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography to examine the results.
