Lassa lashed: X-ray vaccine clue

Date: Jun 15, 2017

Author: David Bradley

Lassa fever can be lethal, it is a severe hemorrhagic disease caused by a single-stranded RNA virus in the arenavirus family. There is currently no vaccine. But that might soon change thanks to X-ray crystallographic work ten years in the making.

Stony coral: NMR and climate resistance

Date: Jun 15, 2017

Author: David Bradley

2D nuclear magnetic resonance (NMR) spectroscopy and ultra-high-resolution 3D imaging have been used to investigate a well-known and previously well-studied stony coral of the Indo-Pacific to reveal that it precipitates minerals through a biologically driven process. The findings suggest that this particular species may be more resistant to climate change than first thought.

Understanding diabetes: Atomic absorption spectrometry assists

Date: Jun 15, 2017

Author: David Bradley

Type 1 diabetes is a major cause of debilitation and premature death. Treating the disorder is complicated and costly. Now, a team in Brazil is using atomic absorption spectrometry and other techniques to look for potential metallic biomarkers for copper, magnesium, selenium, and zinc to correlate their concentrations with the patient metalloproteome.

Journal Highlight: Mutual diffusion driven NMR: a new approach for the analysis of mixtures by spatially resolved NMR spectroscopy

Date: Jun 6, 2017

Author: spectroscopyNOW

A new approach has been established for resolving the NMR spectra of mixtures, relying on the mutual diffusion of dissolved species when a concentration gradient is established within the NMR tube.
