Breeding dogs on the basis of a single genetic test carries risks and may not improve the health of pedigree lines, experts warn. Only a combined approach that makes use of DNA analysis, health screening schemes and pedigree information will significantly reduce the frequency of inherited diseases.
The impact of pollution on wildlife could be made dramatically worse by climate change according to a new study published in the journal PNAS. BBSRC-funded researchers from the University of Exeter and Astra-Zeneca found that clotrimazole, a chemical that disrupts hormones and is commonly used in anti-fungal treatments, skewed sex-ratios in zebrafish in favour of males.
Scientists have found how simple bacteria can restart their ‘outboard motor’ by hotwiring their own genes. Unable to move and facing starvation, the bacteria evolve a replacement flagellum – a rotating tail-like structure which acts like an outboard motor – by patching together a new genetic switch with borrowed parts.
