Crayfish test: Polyaromatic hydrocarbons assessed

Date: May 15, 2014

Author: David Bradley

A predictive model for the determination of average polycyclic aromatic hydrocarbon (PAH) concentrations in the freely dissolved phase and those present in resident aquatic organisms, such as crayfish, is being developed by US researchers.

Electronic prescription: Information improvements

Date: Apr 15, 2014

Author: David Bradley

Safer prescribing of medications could be possible thanks to a better approach for designing medication alerts that are presented in electronic medical records. The new approach, described online in the Journal of the American Medical Informatics Association also increased efficiency and reduced workload for health care providers.

Journal Highlight: Chemometric application for thermal behavior of blends of bamboo with solid fossil fuel

Date: Apr 14, 2014

Author: spectroscopyNOW

The suitabilities as fuels of blends of bamboo biomass with low-rank high-sulfur coal were assessed by thermogravimetric analysis supported by chemometric analysis, correlation and principal component analysis.

Journal Highlight: Decomposition of in vivo spatially offset Raman spectroscopy data using multivariate analysis techniques

Date: Mar 17, 2014

Author: spectroscopyNOW

Spatially offset Raman spectroscopy data were processed with three different multivariate techniques and compared for their performance with a spectrally challenging plastic model system and the analysis of human bone transcutaneously in vivo.

Methylation: Key to chemo epigenetics

Date: Mar 15, 2014

Author: David Bradley

Chemotherapy for breast cancer comes with inevitable acute side effects, but it can also leave a long-term epigenetic imprint on the DNA of the patient's normal white blood cells. Research to scan and analyse hundreds of thousands of putative methylation sites that might be involved in this process could lead to new understanding of the effects of cancer therapy.

Mars: The watery shape of things to come

Date: Feb 15, 2014

Author: David Bradley

Streaks that periodically appear on the surface of Mars could be due to water. A spectroscopic study of these recurring slope lineae (RSL) has not revealed the presence of water nor salts that might be soluble residues. However, the presence of spectral lines due to iron(III) and iron(II) minerals may hint at an aqueous process offering a tantalizing dip of the toe into the Martian waters.
