Topical news at Christmas (with its link to a claimed 'virgin birth') that scientists at Cambridge University have had some success stimulating skin cells with growth factors to convert to early stage eggs and sperm (http://www.theguardian.com/society/2014/dec/24/science-skin-cells-create-artificial-sperm-eggs). Apparently female skin samples can only generate eggs but male material can produce eggs or sperm, a factor related to the presence of the X and Y chromosomes. The intention (if there is a change in the UK Law) is that, eventually, the processes may be used to treat infertility in humans.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
