Fighting fungal infection: detecting signature compounds in breath

Date: Feb 1, 2016

Author: Ryan De Vooght-Johnson

Oral thrush is the most common infection of the mouth, caused by a group of yeasts called Candida. Proper diagnosis currently requires time-consuming tests. Now, German scientists have developed a simple and rapid breath test to diagnose the infection.

Breath test could diagnose colorectal cancer

Date: Dec 1, 2015

Author: Ryan De Vooght-Johnson

Colorectal cancer screening is part of public health programmes in many countries, but compliance is low and there remains a need for better screening tools. According to a new study, a simple breath test could help to diagnose the condition, which kills thousands every year.

Floral quality assurance: tracing the origin of the Damask rose

Date: Nov 1, 2015

Author: Ryan De Vooght-Johnson

The Damask rose originally hails from Syria, but is now grown across the world. Chirality was used to determine the origin and authenticity of its essential oils by measuring enantiomer and diastereomer content using multidimensional gas chromatography.
