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.

Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
