The UK government wants to phase out gas boilers by 2035, to be replaced by heat pumps. We get a sense of the picture for alternative heating technologies across Europe, and Dr David Glew, head of energy efficiency at Leeds Beckett University in the UK discusses the country's plans. Also in the programme, the Â鶹ԼÅÄ's Clare Williamson reports on whether edible insects are likely to become a significant source of protein for humans in the coming years. Plus, the television show Squid Game has become streaming giant Netflix's most popular series. But it has led to a row between South Korea's SK Broadband and Netflix, as the internet service provider is suing Netflix to pay for costs from increased network traffic and maintenance work, thanks to the surge in viewers. June Yoon is a columnist for the Financial Times in Seoul, and explains the background to the dispute.

Today's edition is presented by Rob Young, and produced by Benjie Guy and Susan Karanja.
