Recent studies have suggested that the onset of human dementia is linked to the age-related build up of a protein termed B2M (beta 2-microglobulin) and, unfortunately, this protein is especially likely to build up in patients undergoing kidney dialysis where memory loss can be a common side-effect (http://www.theguardian.com/science/2015/jul/06/memory-loss-in-old-age-breakthrough-offers-dementia-hope-say-researchers). Studies using mice in San Francisco have shown that subjects treated with B2M behaved in memory tasks like much older individuals whereas mice genetically modified not to produce this protein performed well into old age. This current focus on brain protein chemistry suggests that certain proteins are detrimental to memory whereas others can counteract the aging process. Perhaps hope for the (distant) future?
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.

The Comma butterfly ( Polygonia c-album) gets its name from the punctuation-like mark, on the underside of its wings.
