The rise of antibiotic resistance in many pathogens has been driven by the spread of a small number of strains, suggesting that some bacteria may be genetically pre-disposed to evolving resistance. Researchers at Oxford University have tested this hypothesis by quantifying differences in evolvability between pathogen strains and by searching for ‘potentiator’ genes that accelerate the evolution of resistance. Their results are published today in Nature Communications.

Right place, right time: a closer look at DNA folding
Your body is made up of trillions of cells, all with the exact same DNA code to make you, you. But all our cells have different jobs – red blood cells deliver oxygen around the body, stomach cells break up your food and heart cells keep you going. So how can the same set of instructions lead to such different roles? And what impact do mistakes in these instructions have on human health? In this blog, Caz Harrold explains the science that underpins our Royal Society Summer Science Exhibition stand.
