Carbon capture: Solar-powered option

Date: Jun 15, 2012

Author: David Bradley

A US team has suggested a novel reaction mechanism that can mimic photosynthesis in the binding of carbon dioxide using light energy captured by silicon nanowires.

Journal Highlight: 1H-NMR Simultaneous identification of health-relevant compounds in propolis extracts

Date: Jun 4, 2012

Author: spectroscopyNOW

The use of 1H-NMR for the simultaneous recognition of phenolic compounds in complex matrices, such as propolis extracts, has been demonstrated using appropriate tools for spectra pre-treatment and analysis.

NMR gets the needle: Bacterial target pinpointed

Date: Jun 1, 2012

Author: David Bradley

The structure of a "needle" used by various bacteria, among them strains that cause bubonic plague, enterohaemorrhagic colitis, typhoid fever, Shigella dysentery and cholera, to get into host cells has been obtained at atomic resolution using NMR and other techniques. The research could ultimately lead to the development of novel drug to combat these and other diseases.

Journal Highlight: Benchmark calculations of 29Si–1H spin–spin coupling constants across double bond

Date: May 15, 2012

Author: spectroscopyNOW

Benchmark calculations of geminal and vicinal 29Si–1H spin–spin coupling constants across double bond in three reference alkenylsilanes have been carried out at both DFT and SOPPA levels in comparison with experiment.

Walk on by: The light at the end of the track

Date: May 15, 2012

Author: David Bradley

British researchers have created a molecular track to emulate this process and added a small molecule that can shuffle back and forth like a courier on the track.

Nerve block: Halting pain at a snail's pace

Date: Apr 30, 2012

Author: David Bradley

Conotoxins from the predatory cone snail work even at very low levels to block nerve signals. A new NMR spectroscopic study has investigated the structures of a specific conotoxin with a view to developing these compounds, or their derivatives, as novel painkillers.

Journal Highlight: Sucrose in aqueous solution revisited, Part 2: Adaptively biased molecular dynamics simulations and computational analysis of NMR relaxation

Date: Apr 2, 2012

Author:

Molecular dynamics simulations of sucrose in water at various temperatures track closely with experimental results, and are consistent with a model in which sucrose conformational fluctuations are limited.

Fold it: Solid-state NMR unravels proteins

Date: Apr 1, 2012

Author: David Bradley

Researchers have developed a novel solid-state NMR spectroscopic method that uses paramagnetic tags to help them visualize the shape of protein molecules. The technique could be used to help scientists understand the properties of various biological molecules under normal, healthy conditions and also in those that are involved in a range of diseases.

Interacting chaperones: NMR and X-ray combine to unravel combined relationship

Date: Mar 15, 2012

Author: David Bradley

Researchers in the US have combined nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography to gain new insights into the way in which a member of the histone chaperone family of specialized proteins functions.

Journal Highlight: NMR analysis of metabolic responses to extreme conditions of the temperature-dependent coral pathogen Vibrio coralliilyticus

Date: Mar 5, 2012

Author:

The NMR analysis of polar metabolites of Vibrio coralliilyticus grown under normal and stressed conditions revealed a novel bioplastic-type compound in the stressed metabolome, consistent with acute nutrient limitation.
