rssNatural light: Prototyping light harvesters
Date: Sep 1, 2013
Author: David Bradley
A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennae that absorb more sunlight than their wholly natural counterparts. The system could be used to prototype ultraviolet and visible absorbing molecules for solar energy trapping.

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".

Lip sync: Raman raises brand awareness
Date: Sep 1, 2013
Author: David Bradley
Forensic scientists in the UK have demonstrated that Raman spectroscopy can be used to identify the specific brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag and so avoid possible cross-contamination and ensuring a secure prosecution.

Explosive model: MRI mathematics pinpoints bombs
Date: Sep 1, 2013
Author: David Bradley
A three-dimensional model of the Earth's crust and the mantle beneath it can be analysed using the same equations as are used to analyse and interpret magnetic resonance data for display of an MRI. Instead of revealing the presence of a brain tumour or damaged tissues following injury the equations can be used to illuminate the material properties of the Earth's interior which can help to reveal the precise locations of explosions across the globe.

Pale blue dot: Poring over IR data
Date: Sep 1, 2013
Author: David Bradley
In the wake of the NASA Cassini mission turning its cameras towards Earth instead of its usually target the planet Saturn, its rings and moons, astronomers are now analyzing an abundance of infrared and ultraviolet data from the images.

Journal Highlight: A pilot functional MRI study of the effects of prefrontal rTMS on pain perception
Date: Aug 26, 2013
Author: spectroscopyNOW
This exploratory pilot study used functional magnetic resonance imaging to examine the effects of left prefrontal repetitive transcranial magnetic stimulation on brain activity and pain perception.

Journal Highlight: Proteomics analysis of tumor microenvironment: Implications of metabolic and oxidative stresses in tumorigenesis
Date: Aug 26, 2013
Author: spectroscopyNOW
Recent advances in the understanding of the metabolic and oxidative stresses associated with tumor progression with proteomics-based systems biology approaches are highlighted.

Journal Highlight: Phytochemical fingerprints of copaiba oils (Copaifera multijuga Hayne) determined by multivariate analysis
Date: Aug 19, 2013
Author: spectroscopyNOW
Oil samples of Copaifera multijuga Hayne species were characterized by GC-FID and GC/MS and the chromatographic data were processed using hierarchical cluster analysis and principal component analysis to recognize patterns for the chemical composition.

A joint effort: Differentiating types of arthritis
Date: Aug 15, 2013
Author: Steve Down
Four common types of arthritis share a common metabolic profile but there are sufficient variations to provide individual signatures for each disease, according to an international study.

Signs of ageing: Metabolite linked to rate of ageing
Date: Aug 15, 2013
Author: Steve Down
A panel of human metabolites that correlate with age has been identified from a study on thousands of twins, leading to the possibility of a blood test that can predict which people are likely to age rapidly.
