There has been much debate about whether humans have maintained the ability to detect the Earth's magnetic field and to use this sense to orientate themselves. A recent experiment on 34 people (a bit small) has suggested an individually variable brain wave response when subjects are exposed to perturbations of fields in a cage-like enclosure (https://www.theguardian.com/science/2019/mar/18/humans-earth-magnetic-field-magnetoreception). If humans have this capacity, it is generally weak. I think we still need the compass.
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.
