Analysing aldehydes: UHPLC reveals the chemical weapons that crush crustacean reproduction

Date: Dec 1, 2016

Author: Ryan De Vooght-Johnson

Microscopic diatoms may be small, but these silica-clad plankton have their own chemical weapons, producing compounds, such as polyunsaturated aldehydes, that inhibit some of their predators. Scientists from Jena University in Germany have produced an improved method for detecting such compounds, using modern ultra-high performance liquid chromatography.

Quality control ensures safety of chemotherapeutic infusions

Date: Nov 14, 2016

Author: Ryan De Vooght-Johnson

Space and resources are at a premium, which requires cocktails of chemotherapeutic drugs to be prepared side-by-side. But is this method of preparation safe? French scientists investigate.

Friend or foe? Study monitors the helpful plasticizers that rub off on our food

Date: Oct 15, 2016

Author: Ryan De Vooght-Johnson

Since the beginning of time we have faced a battle against invisible microbes. Using reconnaissance gathered during the eighteen and nineteenth centuries, foodstuffs are often vacuum sealed with thanks to plasticizers. But can too much of a good thing be bad?

Cat-and-mouse chase: Test measures in-fashion phenazepam counterfeits

Date: Sep 14, 2016

Author: Ryan De Vooght-Johnson

Malaysian authorities have seized countless illicit pills since 2012 and analyses of these show that backstreet chemists are counterfeiting a new class of benzodiazepine. In response, forensic scientists from Singapore have fought back, describing their tools in Drug Testing and Analysis.

Acid test: can the detection of LSD metabolites prolong LSD’s detectability?

Date: Sep 1, 2016

Author: Ryan De Vooght-Johnson

LSD has mind-bending potency even at trace levels and further evades detection by its instability. Frustrated by LSD’s narrow window of detection, scientists from the University of Zurich and University Hospital Basel teamed up to find out if its derivatives could be used to amplify its detectability.
