Foodomics in action: finding contaminated baby food

Date: Mar 10, 2016

Author: Ryan De Vooght-Johnson

Foodomics – a comprehensive and high throughput approach to analysing food – is emerging as a powerful tool for dietary risk assessment. Scientists from Japan report use of the approach to detect contaminated baby food, identifying pesticides and heavy metals.

Journal Highlight: Prediction of emission spectra of fluorescence materials using principal component analysis

Date: Feb 15, 2016

Author: spectroscopyNOW

A procedure has been developed to approximate the emission spectral data of fluorescent materials of different types from their excitation spectral data using principal component analysis technique.

The spice is right: Spanish saffron samples

Date: Feb 15, 2016

Author: David Bradley

Scientists from the Czech Republic and Spain have used a new cheminformatics "fingerprinting" approach to check data from 44 commercial saffron products to confirm that more than half of products labelled as premium Spanish saffron contained spice from other regions and were thus labelled as such erroneously or fraudulently.

Reading the tea leaves: quality markers for green tea

Date: Feb 12, 2016

Author: Ryan De Vooght-Johnson

Green tea has well-reported health benefits, but the compounds responsible for these effects are still not fully understood. This study used a combination of chromatography and chemometrics to identify the two most important compounds in Brazilian green tea samples, which could be used as quality markers.

Journal Highlight: Detection of Alzheimer's disease signature in MR images seven years before conversion to dementia: Toward an early individual prognosis

Date: Jan 18, 2016

Author: spectroscopyNOW

The performance of a new MR-based hippocampal grading score based on a pattern recognition strategy has been used to assess incident dementia in cognitively intact patients.

Genetic filtering: Informatics indexes spurious mutants

Date: Jan 15, 2016

Author: David Bradley

In genetic diseases it is only 1 or 2 mutations out of possibly thousands that appear to be problematic in the disease. Now, a new filtering algorithm offers improved "needle in a haystack" searching to exclude the problematic false positives.

If you should go skating: The slippery truth about ice

Date: Dec 15, 2015

Author: David Bradley

An icy winter's morning has the scientifically minded wondering about the deceived wisdom of slipping and sliding on ice. Now, a new equation for the frictional shear stress of ice could lead to better ski and skate designs and help us understand better the movement of glaciers and perhaps even the failing of icesheets.

Journal Highlight: A new approach to compressed sensing for NMR

Date: Dec 14, 2015

Author: spectroscopyNOW

A new formalism for spectrum analysis of nonuniformly sampled NMR data places compressed sensing and MaxEnt reconstruction on equal footing, enabling critical comparison of the two methods.

Journal Highlight: Chemometric and phenolic attributes of blended wines assessed by multivariate techniques

Date: Nov 16, 2015

Author: spectroscopyNOW

The qualities of blended wines produced from Vitis vinifera L. Cabernet Sauvignon, Merlot and Sauvignon blanc grapes have been studied using using principal components analysis and cluster analysis.

Microbial hydrogen: Multi-omics explains

Date: Nov 15, 2015

Author: David Bradley

Genome-scale transcript and protein profiling suggest a new hypothesis on the metabolic relationship between oxygenic photosynthesis and nitrogenase-mediated hydrogen production in the ubiquitous oceanic cyanobacterium (blue-green alga), Cyanothece 51142 pointing the way to a previously unknown source of hydrogen that could be renewable and sustainable.
