Tired of tombstones? Put off by plaques? Then a new way of commemorating the dead might be for you: an apple tree, genetically modified to carry strands of your own DNA. The idea for “transgenic tombstones” began as a student project at the Royal College of Arts, London. Now Georg Tremmel and Shiho Fukuhara have been awarded £35,000 by Nesta, the National Endowment for Science, Technology and Arts, to set up Biopresence, a company to make the trees.
