A special edition of the online science magazine show broadcast in front of a live audience from the Cambridge Science Centre.
Sonja Dunbar explains how plants, bacteria and fungi sometimes get along together.
Robin Lamboll, one of the UK finalists of the +famelab Science Communication competition, explains part of the marine nutrient cycle and how we see colour through the medium of poetry.
Michael Conterio talks about how we guide light where we want it to go, whether down optical fibres or shooting powerful lasers through the air.
Helene Gautier talks about sleep, including how different animals sleep differently and some of the changes inside our bodies as we sleep.
And finally we all discuss what science we’re looking forward to over the next 20 years.
