Scientists at Duke University in Durham, North Carolina, USA, have discovered that olfactory cues can indicate pregnancy and foetal sex in the ring-tailed lemur (Lemur catta). Using gas chromatography coupled to mass spectrometry (GC–MS), the team found that lemurs carrying male offspring exhibited a different volatile chemical profile to those carrying a female.

Cedrol, a sequisterpene alcohol found in the essential oil of connifers, could be a potent chemical cue for pregnant mosquitoes seeking the ideal location to lay their eggs. The compound was identified in a study looking at how mosquitoes find the ideal water body to lay their eggs. According to the study published in the Malaria Journal, cedrol could be used in the development of “attract and kill” traps targeting pregnant mosquitoes and reducing the spread of malaria.

Beer is one of the most popular drinks in the world. Based on natural products, quality control to guarantee a product of consistent taste, colour, and composition can be challenging. Amino acids analysis can be used to ensure consistency in the quality of the end-product, and also as an indicator for counterfeiting of branded products. In this article we present a rapid and reliable high performance liquid chromatography–mass spectrometry (HPLC–MS) method to determine amino acids in beer.
