New NMR cancer model: Tracking progress
Date: Oct 15, 2013
Author: David Bradley
A new modelling technique for real-time tracking of metabolic reactions in tumours has been developed by UK researchers. The system based on a simplified computer model of nuclear magnetic resonance spectra could allow oncologists to assess how well their prescribed treatment, whether chemotherapy, radiotherapy or an immunological treatment is progressing without surgical intervention nor the need for regular biopsies.

Plant dynamics: NMR offers cellular clues
Date: Oct 1, 2013
Author: David Bradley
Researchers in the USA have used dynamic nuclear polarization (DNP) nuclear magnetic resonance (NMR) spectroscopy on what they describe as a super-sensitive instrument to locate precisely where a protein binds to plant cell walls, reveal a process that loosens the cell walls and thus explains how plants can grow. The research might ultimately lead to more abundant biomass crop yields for renewable energy.

Meteoric rise: NMR reflections
Date: Sep 15, 2013
Author: David Bradley
Solid-state NMR spectroscopy and other techniques have been used to make an inventory of the insoluble organic molecules found in the Sutter's Mill meteorite that may reflect the chemical resources available to the early Earth. Details of the NMR and gas chromatography-mass spectrometric analyses released upon hydrothermal treatment of a sample from the meteorite are reported in the journal Proceedings of the National Academy of Sciences this month.

Journal Highlight: 1H NMR metabolite fingerprinting as a new tool for body fluid identification in forensic science
Date: Sep 2, 2013
Author: spectroscopyNOW
1H NMR spectroscopy coupled with mathematical strategies has been proposed for the first time as a fast and non-destructive tool for body fluid trace identification in forensic science.

Pernicious problem: B12 stacks up
Date: Sep 1, 2013
Author: David Bradley
Vitamin B12, also known as the antipernicious anaemia factor, is an essential nutrient for humans. Now, British scientists have pinned down the mechanism and route of its biosynthesis using electron paramagnetic resonance EPR) and other techniques in what has often been referred to as the "Mount Everest of biosynthetic problems".

Colon cancer calculated: Metabolic profiling
Date: Aug 15, 2013
Author: David Bradley
Nuclear magnetic resonance (NMR) spectroscopy can be used to obtain a metabolic fingerprint of cancer of the bowel and so determine how far advanced the disease is, according to UK researchers.

Journal Highlight: 3He NMR: from free gas to its encapsulation in fullerene
Date: Aug 5, 2013
Author: spectroscopyNOW
The 3He nuclear magnetic shieldings were calculated for single helium atom, its dimer, simple models of fullerene cages (He@Cn), and single wall carbon nanotubes.

Plague detector: Sweet solution
Date: Aug 1, 2013
Author: David Bradley
Anti-carbohydrate antibodies can be used to identify the presence of the pathogen that causes the deadly disease we know as plague, Yersinia pestis.

Magnetic insights: Playing the percentages
Date: Jul 15, 2013
Author: David Bradley
An international research team has shown that one-dimensional molecular conducting wires can be switched to an insulating state using a weak magnetic field even at room temperature. The finding might offer new insights into the innate navigation systems of migratory birds as well as leading to new technology for magnetic field sensors, inexpensive touch screen displays and high-density magnetic storage for smartphones and other portable devices.
