Beth Shapiro specialises in the ancient DNA of two extinct species, the woolly mammoth and the passenger pigeon, and is associate Professor of Ecology and Evolutionary Biology at the University of California in Santa Cruz. She shares with us her latest research on de-extinction, which is the science of creating an organism which is a member of or resembles an extinct species. While it鈥檚 unlikely any extinct animal will be successfully brought back to life soon, Beth argues that resurrecting extinct traits can be a powerful new tool in biodiversity conservation.聽 Beth鈥檚 latest book is .

Jyotsna Kalavar is actively involved in the revival of Sanskrit as a spoken language in India and the United States, and has been a key contributor to Sanskrit education around the world. She is also a senior volunteer teacher. While Sanskrit has remained as a written and liturgical language throughout the centuries, the numbers of speakers has declined. Some of this has been attributed to the rise of English after colonialism, and also a change in the traditional educational system. Jyotsna speaks about the challenges of modernising a language that was created so long ago, and why it is worth preserving the ancient knowledge locked in its words. Jyotsna Kalavar is also Professor of Human Development and Family Studies at the New Kensington campus of Penn State University in the US.

Bill Smith is an engineer and salvage diver who is leading a project to restore one of the world's most legendary speedboats.

He explains to us the complications of rebuilding such a craft which had the engine of a jet powered hydroplane, and was considered a spectacular feat of engineering.

In our Sixty Second Idea to improve the world, the Sanskrit specialist Professor Jyotsna Kalavar suggests having a sofa or chair that can be remote controlled to make the occupant stand. The sofa represents passivity, and by making the sitter stand upright it would encourage efforts to revive oneself, move forward and be energetic.
