Journal Highlight: Rapid assessment of the illegal presence of 1,3-dimethylamylamine (DMAA) in sports nutrition and dietary supplements using 1H NMR spectroscopy

Date: Oct 6, 2014

Author: spectroscopyNOW

A proton NMR method was developed and validated for measuring 1,3-dimethylamylamine in sports nutrition and dietary supplements and is recommended for routine use in food testing, customs or doping control laboratories.

Dynamic sugars: Sweet approach to behaviour

Date: Oct 1, 2014

Author: David Bradley

The dynamic behaviour of complicated sugar chains in solution has been followed at atomic resolution using a combination of a sophisticated nuclear magnetic resonance spectroscopic technique and a novel molecular dynamics simulation technique.

Planetary nano: Orbital system

Date: Sep 15, 2014

Author: David Bradley

German researchers have produced nanoparticles surrounded by a group of smaller nanoparticles in what might whimsically be described as a system resembling a tiny planet with orbiting satellites. Nuclear magnetic resonance spectroscopy and other techniques reveal the details.

Journal Highlight: Aluminum incorporation in the C–S–H phase of white portland cement–metakaolin blends studied by 27Al and 29Si MAS NMR spectroscopy

Date: Sep 1, 2014

Author: spectroscopyNOW

The composition and structure of the calcium-silicate-hydrate (C–S–H) phases formed by hydration of white portland cement–metakaolin (MK) blends have been investigated using 27Al and 29Si MAS NMR.

Terrestrial NMR: Extra

Date: Sep 1, 2014

Author: David Bradley

The Earth's magnetic field is strong enough for experiments in low-field NMR spectroscopy according to a research team from Lawrence Berkeley National Laboratory, which is developing the technique for analysis of fluids in situ in their native environments.

Chemical rewiring: Nerve growth

Date: Aug 15, 2014

Author: David Bradley

New research from and international team using NMR spectroscopy suggests that a single, small molecule might be able to persuade nerves damaged by injury to grow new connections, offering a future hope for people who suffer spinal injuries and paralysis.

Journal Highlight: Color-discriminating retinal configurations of sensory rhodopsin I by photo-irradiation solid-state NMR spectroscopy

Date: Aug 4, 2014

Author: spectroscopyNOW

The photoreactions of sensory rhodopsin I were monitored with the 13C NMR signals of [20-13C]retnal-SrSRI using in situ photo-irradiation solid-state NMR spectroscopy.

Autoimmune mechanism: NMR and X-ray clues

Date: Aug 1, 2014

Author: David Bradley

NMR spectroscopists, X-ray crystallographers and their colleagues have taken an important step closer to understanding the molecular mechanism behind autoimmune diseases. They have solved the three-dimensional structure of the Roquin protein when it is bound to messenger RNA. The results revealed that there is a much wider range of functionally important Roquin binding partners than previously assumed.

Multitasking protein: Nucleophosmin 1

Date: Jul 15, 2014

Author: David Bradley

Nuclear magnetic resonance spectroscopy has been used to demonstrate how one segment of an important regulatory protein, nucleophosmin 1 (NPM1), helps it to fulfil several roles, including tumour suppression, according to researchers at St Jude Children's Research Hospital, Memphis, Tennessee and the Medical Research Council Laboratory of Molecular Biology, in Cambridge, UK. The findings could have implications for the development of novel anticancer drugs.

Cagey about water: NMR in a fullerene

Date: Jul 1, 2014

Author: David Bradley

The all-carbon, soccerball-shaped fullerene, C60, molecule provides the most compact of cryoscopic NMR tubes for studying the behaviour of water, according to researchers at the Universities of Nottingham and Southampton, in UK and Columbia University in New York, USA.
