This week we look into the science of explosives to find out what happens when something blows up and how an understanding of this can help protect people from an explosion. We also reveal how our antibodies fight the Salmonella bacterium and how this new insight could lead to a vaccine against this deadly infection in Africa. Plus, we bring you the latest science news and reveal how pigeons find their way, in Question of the week!
