New paper I was lucky to be a part of investigating human dental enamel periodicity and sexual dimorphism has just been published in the Journal of Structural Biology. The study, led by Dr Patrick Mahoney at the University of Kent in the UK, provides evidence that the human skeletal biorhythm is dimorphic. The paper is open access for 50 days.
My masters student's (Meg Walker) paper reporting preliminary descriptions of bone histology in a fossil and modern wombat is now out in Australian Mammalogy. We had a very limited sample size, but this small study is constructing hypotheses that can be tested in the future using a larger wombat bone sample size. Wombat bone microstructure may reflect a wombat's adaptation to the burrow environment...
A very cool study I have been lucky to be involved with, led by Patrick Mahoney at the University of Kent in the UK, investigating skeletal biorhythm and sexual dimorphism in humans, has been accepted for publication in the Journal of Structural Biology! The rhythmical nature of hard tissue growth is retained by teeth in the form of enamel long period lines (that can be examined using histological methods). In our new paper we tested whether this rhythm differs between the human sexes, because aspects of our skeletal morphology, such as stature, are sexually dimorphic. Dental thin sections from 94 modern individuals in England showed that indeed the dental measures of this rhythm differ between males and females. The paper provides first evidence that this dental rhythm may be one of the factors that influences how dental morphology is expressed in males and females.
