Dogs, descended from wolves, were the first animals to be domesticated by humans, some 40,000 years ago. New research, using modern DNA sequencing, is unravelling the evolutionary history of our canine companions.
By sequencing the genome of this single-celled coccidian parasite, scientists hope to develop better vaccines to protect poultry from a disease that causes severe diarrhoea and death.
From exploding worms to cannibal crickets and adored arachnids to bewildering blackberries, Alison Cranage picks out the more bizarre discoveries we've made
From one human genome to hundreds of thousands, to every single cell in the body, to the genome of every species on the planet – DNA sequencing is accelerating. On our 25th anniversary we look at the evolution, application and potential of this powerful science.
