Synopsis

Scientists following in the footsteps of Edwardian explorer, Douglas Mawson, have been trapped in pack ice in the Antarctic. The Chinese vessel that came to their rescue also became "beset" in the ice. The BBC's Andrew Luck Baker talks to Adam Rutherford about the catacylsmic event that caused multi-year ice to break away and trap the Academik Shokalskiy and Professor John Turner of the British Antarctic Survey underlines the importance of differentiating between extreme weather events and the impact of climate change.A team at Rothamsted Research in Hertfordshire has succeeded in genetically engineering plant seeds to contain the Omega-3 oil usually found in oily fish. Seeds from Camelina sativa (false flax) plants were modified using genes from microalgae - the primary organisms that produce these beneficial fatty acids.The oil has now been incorporated into salmon feed to assess whether it's a viable alternative to wild fish oil. Dr Johnathan Napier tells Melissa Hogenboom that he hopes the plants will pro
