Oxford SciBar: 'Spirals in time: exploring the scientific wonders of seashells' In her latest book, Spirals in Time, as featured on BBC Radio 4's Book of the Week, marine biologist Dr Helen Scales uncovers the secret lives of the animals that make sea shells (the molluscs) and ponders how people have used their shells for millennia as everything from sex symbols and money, to the inspiration behind new materials and medicines. Helen delves into the fascinating science of shells and molluscs, including stories of how researchers finally solved the mystery of how so many beautiful shells are made. Come along to hear about some of the latest discoveries emerging from this often underrated group that includes some of the smartest, oldest and toughest animals on the planet.
