In this week’s programme Adam asks some intriguing questions: how can scientists save the planet from a tide of crisp bags and polystyrene pizza packaging; how easy is it for the eye to fool the brain; how can we protect our coasts from rising sea levels; and who’s afraid of the big bad wolf?

You’ll find the answers to all these questions at the Hidden Worlds exhibition, part of the Bangor Science Festival. Adam previews Hidden Worlds and meets some of the Bangor University scientists who’ll be involved, including Peter Haswell who’s studying the relationships between wolves, humans and other animals in the forests of Croatia. He also talks to Serinde van Wijk and Martin Skov about their work with the Welsh Government’s Low Carbon Energy and Environment Research Network - Serinde tells Adam about a project to store carbon dioxide in disused mines and Martin explains the importance of salt marshes in preventing coastal flooding.  

Meanwhile, Rebecca Snell from Bangor University’s BioComposites Centre shows Adam how to prevent landfill sites being overwhelmed with crisp bags and polystyrene pizza bases as she shows Adam some sustainable, biodegradable food packaging; psychologist Kami Koldewyn demonstrates some optical illusions which scramble Adam’s brain; and marine ecologist Katherine Griffith introduces him to some of the inhabitants of the hidden undersea world – starfish, crabs and sea urchins – which will be at the exhibition for visitors to see and touch.

The Hidden Worlds exhibition, part of the Bangor Science Festival 2015, takes place at the Brambell Building, Deiniol Rd., Bangor on Saturday 14th March between 10 am and 4 pm.
