On Thursday, April 27, 2017 two girls from the Theodor-Heuss-Gymnasium in Göttingen got an insight into the work at the University of Göttingen. Prof. Ernst Wimmer showed the schoolgirls how everyday work looks like in a science laboratory. The photo shows the girls with micro-pipettes in their hand in the molecular biology laboratory.
The red flour beetle Tribolium castaneum is an emerging insect model organism representing the largest insect order, Coleoptera, which encompasses several serious agricultural and forest pests. Despite the ecological and economic importance of beetles, most insect olfaction studies have so far focused on dipteran, lepidopteran, or hymenopteran systems.
We present in "BMC Biology" the first detailed morphological description of a coleopteran olfactory pathway in combination with genome-wide expression analysis of the relevant gene families involved in chemoreception.

Science AAAS wrote in their newest issue: "Sex comes in many forms, even when considered at the molecular level. In different animals, the chromosomes and specific genes that function in sex determination vary widely. As a case in point, the familiar housefly displays a highly variable sex determination system. In this animal, the male determiner (M-factor) instructs male development when it is active, but female development results when it is inactive. Sharma et al. now identify the housefly M-factor, which arose via the co-option of existing genes, gene duplication, and neofunctionalization. The findings elucidate the remarkable diversity in sex-determining pathways and the forces that drive this diversity."
