Is gene editing the future of food?

Loading player...
The world’s harvests are coming under increasing pressure from extreme weather events, disease and deteriorating soil health – problems that are set to get worse in the next few decades. Could one solution be to genetically edit our food to make it more resilient? With the UK’s recent announcement that it will ease the rules for growing gene-edited crops in England, Madeleine Finlay investigates what it will mean for scientists researching the technology, and why it could become a critical tool for the future of our food.

‘Beautiful blobs’: can scientists build life from scratch?

Researchers claim they are closer to creating life from nothing after building tiny, quivering blobs that use lab-made DNA to feed, grow and multiply in a dish. To find out how significant this step is, and where scientists hope it will lead, Madeleine Finlay hears from co-host Ian Sample and…

Reflecting pool algae: the science Trump needs to know

The Lincoln Memorial reflecting pool in Washington DC has hardly been out of the news since April when President Trump vowed to have it renovated, and painted ‘American flag blue’ by 4 July. Despite the pool being stripped, cleaned, coated and refilled, within days the algae that has plagued it…

Nature or nurture: can genes shape our behaviour?

How much do our genes determine about our lives, and could they influence traits like risk-taking, antisocial behaviour or even violence? Ian Sample talks to Kathryn Paige Harden, a behavioural geneticist and professor of psychology at the University of Texas at Austin who studies how genetic factors shape human behaviour…
