Making Fish Oils in Plants – a Sustainable Source of Healthy Fats

There is now ample evidence that omega-3 fish oils are essential components of a healthy diet, contributing to a reduced risk of cardiovascular disease and other metabolic pathologies. These beneficial fish oils are normally obtained either through the consumption of oily fish or via supplements, but both sources are dependent on the wild capture of fish from the oceans and as a consequence, a matter of concern in terms of sustainability and environmental footprint. At Rothamsted, we have been working on using plant genetic engineering to produce plants which have the capacity to make omega-3 fish oils, something that no native higher plant has the capacity to do. With this approach, we have successfully developed a terrestrial source of omega-3 fish oils, no longer dependent on extraction of marine resources from the oceans. This novel oil is clean and sustainable, and has been validated in both animal and human studies. We have also carried out a number of GM field trials at Rothamsted and in N. America to demonstrate that our plants can grow under real-world conditions. We believe that our GM omega-3 fish oils can help fill the gap between supply and demand in the ever-growing quest for these oils, ultimately leading to better nutrition for all.

Milankovitch Cycles

It has long been realised that the Earth has seen large variations in temperature in the past, and one of the first people to speculate about the cause was a Scotsman, James Croll, who suggested it was due to changes in the Earth's orbital motion. This idea was expanded on by Milutin Milankovic, a Croatian scientist who developed a mathematical theory of climate based on how the radiation received by the Earth changed with time. Although he encountered a lot of scepticism at the time he published his ideas the subsequent analysis of the temperature record as seen from core samples has shown his work to have been largely correct. The talk will look at the mechanisms involved and see what this tells us about where the Earth's climate is heading.
