This Obituary by James M. A. Turner, Shantha K. Mahadevaiah, Arthur P. Arnold and Robin Lovell-Badge was recently published in Development. Paul Burgoyne was an outstanding mouse geneticist and developmental biologist who made fundamental discoveries about the sex chromosomes and their biology. He was born on 10th January 1946, spending most of his[…]
Stories of sneaky sheep, substandard racing stallions, the Vikings of the Scottish Isles and news from the front lines of the sperm wars.
The story behind our recent paper in eLife. Rapid turn over of sex determination mechanisms provides biologists with an elegant study system connecting sexual selection to molecular evolution. Striking examples of this turnover are found in African cichlids, where multiple sex determination signals exist not only within the same genera, but sometimes within the[…]
A discussion of our recent paper: Annick Sawala & Alex P. Gould (2017). The sex of specific neurons controls female body growth in Drosophila. PLoS Biology, October 4 2017. In the beginning… The story behind this study provides yet another example of where the pursuit of a few chance observations developed into an interesting project[…]
Bruno Hudry and Elizabeth J. Rideout Male and female fruit flies differ in many aspects of development and physiology. For example, males and females differ in abdominal pigmentation, sex comb formation, courtship behaviours, the development and wiring of the central nervous system, internal reproductive organs, and genital morphology. Many elegant studies on the genes that[…]
Here is some developmental biology related content from other journals published by The Company of Biologists. Deducing the stage of origin of Wilms tumours from a developmental series of Wt1 mutants Wilms’ tumours, paediatric kidney cancers, are the archetypal example of tumours caused through the disruption of normal development. In this[…]
