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.

Weeding out cannabinoid metabolites

Date: Aug 18, 2016

Author: Ryan De Vooght-Johnson

Our body invariably attaches cannabinoids to glucuronides with variable bonds not suitable for a one-size-fits-all hydrolysis preparation. Accordingly, researchers from the University of Basque Country in Spain set out to devise a tandem-hydrolysis approach in the hope of providing tools capable of picking apart quackery from quality evidence.

The bee’s knees: neonicotinoid insecticides in bee pollen quantitated in record times

Date: Jul 15, 2016

Author: Ryan De Vooght-Johnson

Neonicotinoid insecticides used by farmers to protect their crops pose an unintended existential threat to bees, necessitating tools to both study their toxicity and police their restricted use. Researchers from the University of Valladolid, Spain, have devised a quick and easy method for the quantitation of neonicotinoids in bee pollen by UHPLC-qTOF in record time.
