Dr. Lynne Kelly is an Australian writer, researcher and science educator. She has written books on skepticism, crocodiles and spiders; and her latest book The Memory Code examines the traditional memory techniques of non-literate peoples. Her theory on the purpose of the Stonehenge megalithic, which she believes served as a center for the transmission of knowledge among Neolithic Britons, is rapidly gaining recognition among anthropologists. Ed, Penny and Lucas caught up with Lynne to talk all things memory. |

According to a study published in the journal Science, pretty thick - between 130 and 190km! 00:10:57 Mars' "bow shock" - where charged particles from the Sun interact with the red planet's atmosphere - has been studied by a team of European scientists. They found that the bow shock's location changes over several Martian years, for a variety of reasons. 00:14:43 Artificial organs don't have to be full sized and they don't have to be for transplants.
