Summary
Fast and portable genome testing is unlocking the secrets to ourselves and the environment we live in.
It's impact could lead us to fundamentally remake our approach to medicine, agriculture, the environment, conservation and our selves.
In this episode we hear from Dr Lara Urban, a geneticist studying the kakapo in New Zealand, Dr Gordon Sanghera, CEO of Oxford Nanopore Technologies and Professor Anna Schuh, professor of molecular diagnostics at the Department of Oncology at Oxford University and visiting professor at Muhimbili University of Health and Allied Sciences in Tanzania.

| 0:31.8 | As of today, there are 197 adults left in the entire world. So they are very, very endangered. |
| 0:40.4 | There is hope, though, scientists are now using fast and portable DNA sequencing devices |
| 0:46.3 | to unlock the secrets to all sorts of species, including our own. It could lead us to fundamentally |
| 0:53.3 | rethink our approach to all life on the planet |

| 1:03.8 | There is a cancer pandemic. Most of these infection-related cancers are actually in sub-Saharan Africa. |
| 1:09.6 | It is much more important in those settings to diagnose |
