Europe swelters in 'heat dome', and Martin Rees on aliens

In this week's show, wildfires continue to race across the world in Canada, Ireland, Scotland and Italy. Why are they happening, and what can we do to prevent them? Plus, scientists track neighbourhood food consumption from DNA in sewage, the first evidence of an "exomoon" orbiting a planet outside our solar system, and how tiny "algebots" can deliver cancer chemotherapy in the bladder. What makes these critters remote-controlled? Like this podcast? Please help us by supporting the Naked Scientists

This week, our Titans of Science series continues with neuropsychologist and author Adrian Owen. Adrian's work has focused on determining how different parts of the brain contribute to functions such as cognition and memory, and famously led to him being being able to communicate with a patient in a long-term vegetative state using a brain scanner. Here he retells the story, and explains the basis of what we call consciousness... Like this podcast? Please help us by supporting the Naked Scientists

A new drug called Trontinemab, which could stop Alzheimer's disease, is about to start clinical trials. How does it work? Also, scientists at the University of Oxford have created a vaccine to fight Ebola; researchers have documented three different types of severe pneumonia; and why the discovery of sugars in space matters.

Titans of Science continues with plant biologist Enrico Coen, a professor at the John Innes Centre in Norfolk. His work investigates how genes move and interact to create tissue shapes during plant development, and how this process varies to produce such a wide range of plant forms. In this episode, we find out how Enrico's early work on fruit flies paved his path to plants, and his work on 'jumping' genes and their effect on plant variation. He's been speaking with Chris Smith.

Titans of Science returns with Tara Spires-Jones, a world-leading neurobiology researcher and Director of the Centre for Discovery Brain Sciences at the University of Edinburgh. She studies the mechanisms and reversibility of neurodegeneration in Alzheimer's disease and other degenerative brain diseases. We explore Tara's path to neuroscience, the history and biology of Alzheimer's, and treatments developed to overcome it. Tara has been speaking with Chris Smith. Like this podcast?

Coming up, Rachael Ralph explores the role of science in music. At Trinity College, Cambridge, engineer Hugh Hunt demonstrates how sounds are made; Ian Cross discusses turning experimentation into music and instruments; Trinh Nguyen examines music and development in babies; and Jacopo de Berardinis explains AI's role in the 21st-century music revolution.

Coming up, most of Europe smashes June temperature records. But what is the 'heat dome' that's driving this extreme weather? Plus, why HPV vaccine rates are declining despite a huge reduction in cervical cancer deaths; Sonia Shah on her book The Fever: How Malaria Has Ruled Humankind for 500,000 Years; and former Astronomer Royal, Lord Martin Rees, on aliens.

Coming up, we explore the life and times of our ancient ancestors, and what they can teach us. In this episode, Lee Berger tells us about the Homo Naledi species that ritualistically buried their dead; George Nash on remarkable cave paintings in South Wales; Andrea Manica explains how our ancient ancestors evolved sickle cell to sidestep malaria; and Rod Flower on our forebears making medicine and mind-altering drugs.
