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.

Reaching the Heights?
A Swedish study, based on large numbers of citizens of that country, has strongly suggested that tall people are more likely to develop cancers than their restricted height counterparts (http://www.theguardian.com/society/2015/oct/01/taller-people-more-likely-to-get-cancer-say-researchers). This applies to both males and females and could be a consequence of their simply having more cells (to go cancerous) or a higher intake of foods. Having said that, there is also a strong link between human growth hormone levels (tall people have more of this, certainly at some stages of development) and growth of some cancers. I feel quite relieved to have reached my 70s, having sped to 2M by age 12! There are, however, some advantages to being tall. There is a positive association between height and intelligence; you get better views in a crowd; basketball is an option for you and you may even be better paid.

No Womb
Interesting news that the go-ahead to attempt 10 womb implants to women who lack the organ have been given (http://www.theguardian.com/lifeandstyle/2015/sep/29/10-women-receive-go-ahead-for-first-ever-womb-transplants-in-uk). This seems to be a consequence of some apparently successful Swedish trials, apparently involving donor relatives. In the case of the UK studies, the wombs will come from deceased individuals and there will have to be some basic matching. The idea is to take eggs from the recipient's ovary and to attempt a maximum of two in vivo fertilisation processes before removing the womb. The reason for this is that the women will have to receive immunosuppressive drugs to prevent the rejection of the donated organ (these are a health hazard as they reduce general disease resistance). I suspect that it is low on people's list of priorities (when what they want is a baby) but I wonder if they have taken into account a substantial body of evidence suggesting that these drugs can have profound behavioural effects on the developing foetus?
