Journal Highlight: Deep sequencing of hepatitis C virus reveals genetic compartmentalization in cerebrospinal fluid from cognitively impaired patients

Date: Oct 17, 2016

Author: spectroscopyNOW

Deep sequencing technologies were used to investigate hepatitis C virus genetic compartmentalization between plasma and cerebrospinal fluid from patients with known levels of fatigue and cognitive impairment.

Deconvolution of complex spectra outsourced to algorithm

Date: Oct 15, 2016

Author: Ryan De Vooght-Johnson

A new algorithm for spectral deconvolution and xenobiotic identification aids forensic toxicology investigations, uncovering more xenobiotics in blood samples than humans alone.

Lipstick traces: FTIR calibration

Date: Oct 15, 2016

Author: David Bradley

Lipstick is a widely used cosmetic the world over. However, it is commonly formulated with animal fat, and lard in particular, which does not sit comfortably for some people with particular ethical, moral and religious beliefs. A new approach to extraction and analysis by multivariate calibration of Fourier transform infrared (FTIR) spectroscopy has been demonstrated by researchers in Indonesia.

Mistaken identity: Tools help to distinguish the medicinal from the endangered

Date: Oct 1, 2016

Author: Ryan De Vooght-Johnson

Imagine you have a doppelgänger who indulges in delinquent behaviour—behaviour which you’re constantly and falsely being accused of committing. In a strikingly similar set of unfortunate circumstances, three species of the Panux genus have been pushed to the brink of extinction, based solely on another’s reported successes.

Picture perfect: model captures programmed temperature gas chromatography panorama

Date: Sep 14, 2016

Author: Ryan De Vooght-Johnson

The more data accounted for, the more accurate the calculation. Ever since the 1960s, scientists have attempted to capture the mathematical panorama, and here researchers from Hawaii and China attempt to add yet more detail to the picture.

Journal Highlight: Tracing the origin of beer samples by NMR and chemometrics: Trappist beers as a case study

Date: Sep 12, 2016

Author: spectroscopyNOW

An NMR and chemometric analytical approach to classify beers according to their brand identity has been developed within the European TRACE project using Trappist and non-Trappist beers.

The power of flower tea: Components of Coreopsis tinctoria mapped out for the first time

Date: Sep 1, 2016

Author: Ryan De Vooght-Johnson

How do you make the best cup of tea? One size does not fit all, that’s for sure. Many may be urged on by their taste buds, some by their caffeine urges, whilst others may be conscious of their health. Fixated by the latter, scientists based in China applied cutting-edge analytics to decipher: what is in our Coreopsis tinctoria flower tea?

Another pair of eyes: improved ability to measure consistency of ophthalmic drug dosages

Date: Aug 17, 2016

Author: Ryan De Vooght-Johnson

Measuring the error of your novel analytical test one-variable-at-a-time is painstakingly slow, not to mention the huge amounts of data generated. In response, researchers from the University of La Laguna in Tenerife set out to devise a cheap and accessible test capable of measuring the conformity of triamcinolone acetonide within eye hydrogels using accessible technology and new-generation data crunching.
