Journal Highlight: Evaluation of the spectral accuracy of mass spectrometers using compounds containing Cl or Br atoms

Date: Dec 5, 2016

Author: spectroscopyNOW

Two methods with lower theoretical uncertainties have been developed for evaluating the spectral accuracy in single and triple quadrupole mass spectrometers.

Biowarfare agents: Toxin testing

Date: Dec 2, 2016

Author: Steve Down

Toxins that have been added to foods as chemical and biological warfare agents can be detected using a novel proteomics approach which bypasses the need for antibody-based isolation by employing isotope-labelled versions of the toxins.

Christmas treats: Irradiated turkey off-odour

Date: Dec 1, 2016

Author: Steve Down

Christmas cooks this year might be surprised to learn that raw turkey breast develops an off-odour following irradiation treatment designed to kill pathogens, say researchers in the US, who also studied the factors behind the accompanying change in colour.

Futuristic MS methods found feasible for forensics, pharma and food

Date: Dec 1, 2016

Author: Ryan De Vooght-Johnson

Curiosity killed the cat—allegedly—but also allowed Sapiens to flourish. At the heart of humankind’s endless curiosity lies a labyrinth of data, verging on too complex and too vast for humankind to process. In response, scientists have handed their MS/MS data to silicon, to great success.

Precision Raman: Effect in the field

Date: Dec 1, 2016

Author: David Bradley

New technology that could change the way in which electronics are printed facilitates high quality, direct spray deposition of semiconducting molecular crystals on to any surface. The precise nature of a single crystal field-effect transistor made this was has been ascertained using polarised Raman spectroscopy.

Light switch: Autumn leaves

Date: Dec 1, 2016

Author: David Bradley

Yellow chlorophyll decomposition products are environment-responsive chiral photoswitches researchers in Austria have found using UV-Vis and nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography studies.

Graphene plasmons: So NIR

Date: Dec 1, 2016

Author: David Bradley

Efficient absorption enhancement at a wavelength of 2 micrometres by graphene has been demonstrated with the plasmons of nanoscale graphene discs by researchers in Denmark.

Poverty and the growing brain: MRI clues

Date: Dec 1, 2016

Author: David Bradley

Poverty can have a seriously detrimental effect on the childhood development of the brain. However, a magnetic resonance imaging (MRI) study of children of families participating in the Strong African American Families Program has shown for the first time that this effect can be countered by supportive parenting and family relationships.
