In 1936 the last captive Thylacine, or Tasmanian Tiger as it's more widely known, died in Hobart Zoo in Australia. In 1982, the species was officially declared extinct. Now, evolutionary biologist Professor Andrew Pask and his team at the University of Melbourne want to bring the marsupial back from the dead using its remaining DNA. The only reason this de-extinction can even be contemplated is because of new gene editing technology. Emma Keeling talks to Professor Pask about how this can be achieved and why bringing certain species back is so critical for the environment.

Future of Wind

Wind power has long been a mainstay of sustainable energy production. Giant wind turbines dominate skylines across the world. However, the structures are noisy, cumbersome and require regular maintenance. Reporter Guy Henderson travelled to Madrid, Spain to meet a company that's found a new way to make energy using a phenomenon which has previously been an engineer's worst nightmare. Vortex Bladeless is developing ground-breaking technology that uses a vibration resonant cylinder which oscillates in the wind, generating power through the use of a dynamo.
