In the course of experiments undertaken in this department to throw further light on the co-ordination of pigmentary changes in Amphibia, various indications have arisen to suggest that the pressor and melanophore components of extracts of the pituitary gland are not one and the same substance. The separate identity of the pressor and oxytocic components first indicated by Dale and Dudley (1921) has now been established beyond reasonable doubt by the work of Schlapp (1925) and of Draper (1926) who have availed themselves of a method of pressor assay devised by Hogben, Schlapp and Macdonald (1924) to permit comparison with a precision of the same order as that of Dale’s oxytocic standardisation. By the methods of separation used by Schlapp and a third method used by Dreyer and Clark (1924), it is not possible to state with certainty that the melanophore and pressor activities are referable to separate...
Embracing allyship in experimental biology to help close the gender gap
In their Perspective, Janneke Schwaner and Ksenia Keplinger propose 10 useful strategies for experimental biologists at all career stages to become active allies for gender diversity and inclusion and to help close the gender gap in our field.
The Company of Biologists celebrates its first Global South Workshop
In March 2024, Andrea Fuller and Kênia Bicego organised the first Global South (GS) Workshop hosted by The Company of Biologists - How Global South Research Can Shape the Future of Comparative Physiology - bringing together ECRs from the GS and international experts in the Kruger National Park, South Africa. Find out about this extraordinary meeting in our Perspective.
High-resolution WildPose 3D scans revolutionise biomechanics in the wild
Collecting detailed kinematics from animals in the wild is a holy grail of biomechanics, and now Naoya Muramatsu and colleagues reveal the extraordinary observations that they have made with their new WildPose wildlife motion capture system in South Africa.
