It has apparently proved possible to separate X and Y human sperm on the basis of their differential movement (https://www.theguardian.com/science/2019/aug/13/sperm-separation-method-may-allow-gender-selection-in-ivf). This might well lead to the technique being used to specify sex in in vitro fertilisation programmes. Although favouring one sex is generally a bad idea (particularly seen in some cultures), there are some genetic conditions where specifying the sex could reduce the risk of passing on harmful conditions.
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.
