Gas Chromatography Helps Repel Insects
The BBC reports that British scientists have used gas chromatography to isolated natural chemicals that make some people smell unpleasant to mosquitoes. This discovery could potentially decrease the role of blood-sucking insects as disease carriers.
The BBC reports that British scientists have recently used gas chromatography to isolated the natural chemicals which make some people smell unpleasant to mosquitoes. This discovery could potentially decrease the role of blood-sucking insects as disease carriers.
The technique enabled the scientists to break down human odours into their individual chemical components. Then electroantennography allowed them to record the responses in the mosquito's antennae.

Measuring Vitamin K1 Concentrations in Dogs with Chronic Enteropathy Using LC–MS/MS
May 14th 2025A joint study between the University of Tennessee (Knoxville, Tennessee) and the University of Pennsylvania School of Veterinary Medicine (Philadelphia, Pennsylvania) compared directly measured vitamin K1 (vitK1) concentrations in healthy dogs and dogs with chronic enteropathy (CE) using liquid chromatography tandem mass spectrometry (LC–MS/MS); they also investigated whether supplementation of vitK1 in dogs with CE would significantly increase vitK1 concentrations.
