There is considerable concern about the development of antibiotic resistant bacteria (largely driven by over-prescribing and use, by farmers, in meat production). A tiny boost has been received with news from animal research that two retinoids (relatives of vitamin A), developed to treat acne and skin cancer, seem to have potential for use in countering MRSA (methicillin-resistant Staphylococcus aureus) infections (https://www.theguardian.com/society/2018/mar/28/discovery-mrsa-busting-antibiotic-hope-resistant-superbugs). These retinoids (in combination with an antibiotic) seem to make the membranes of this bacterial species more leaky (a bit like the actions of complement proteins). Unfortunately, these drugs do not appear effective against other so-called 'latent' (generally dormant but capable of being activated) infections but they do offer a new line of investigation for a currently intractable problem.
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.
