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.

Bite of the Lone Star Tick
The Centers for Disease Control and Prevention currently record almost 0.5 million US citizens with the alpha-gal syndrome. Sufferers get this syndrome, from the bite of the Lone star tick. This blood-sucking arachnid, has a characteristic single spot on its dorsal shield (https://www.theguardian.com/us-news/2023/jul/27/tick-bite-red-meat-allergy-ags-cdc). The syndrome is an allergy to a sugar, alpha galactose. Alpha galactose isn't found in humans, It's, however, found in red meats (beef, lamb, pork, rabbit and venison), as well as mammal products (gelatine and dairy materials). Ingesting any of these causes sickness and diarhoea. The symptoms can be life-threatening but, as yet, there's no effective treatment for the condition. Patients can't even take any medication that's encapsulated in gelatine.
