The Naked Scientists Podcast Folgen

The role of lasers in biomedicine goes under the spotlight this week as we explore the workings of photodynamic cancer therapy, find out how laser tweezers can be used to force-feed bugs to white blood cells and hear how a new technique uses laser-powered DNA nanoswitches to spot specific genes. Also, why the proton just got smaller, prompting a reevaluation of some trusted laws of physics, how antidepressants in seawater can make shrimps swim towards danger and a novel mechanism for natural selection - beneficial bacteria! Plus, in Kitchen Science, what the patterns produced by laser light... Like this podcast? Please help us by supporting the Naked Scientists

We explore the explosive science of volcanoes this week! We find out what you can learn from drilling into a restless volcano, how gravity is used to "weigh" volcanoes and watch them fill with magma, and we explore the theories behind volcano formation. Plus, we hear about the genes that could mean you'll live to be 100, fossil evidence of the earliest multi-cellular organism and the signs that Sabre-toothed tigers packed a mighty punch, as well as a big bite. In Kitchen Science, we get messy with a cola and wallpaper paste eruption! Like this podcast? Please help us by supporting the Naked Scientists

Why do we have eyebrows? Can we taste food if we can't smell it? What's a cold sore? This week, we take on your science questions, as well as explore the world of social gaming, and find out how much it costs to fly an England flag from your car. We'll be asking if altitude affects how a football flies, if a large enough fan could propel a spacecraft and how spiders spin webs from one tree to the next. Plus, why size matters in bird beaks, how plant roots cope with competition and building lungs in the lab! Like this podcast? Please help us by supporting the Naked Scientists
