The Science of Farming

Peas in pods. (c) Gaetan Lee

We dig into the science of farming this week with a look at how agriculture can adapt to a changing climate, how scientists are striving to produce a perfect pea and a new initiative to turn native African fruit trees into the next commercial blockbusters. In Kitchen Science we use chromatography to reveal the colours concealed in chlorophyll, and in this week's news round-up, a new way to finger criminals using the trail of bacteria they leave behind, combating cancer with synthetic lethality, and how scientists have turned mosquitoes into flying vaccinators...

    Dear Chris   Also on a recent farming programme they explained that satelite pictures of farmland combined with computer programming of the distribition of fertilsers from a tractor could optimise yields using no more than the necessary amount of fertiliser. Suprisingly they s...

  • 49:44 - How do cancers spread between organs?

    With the recent sequencing of various lung cancer and melanoma genomes, it seems that the specific sets of mutations that cause one type of cancer differ from those that cause another type of cancer. If this is the case, how does cancer spread from one organ to another? F...
