Miniature lungs, breasts and other organs are being grown in dishes so scientists can study how they form, why they succumb to disease and how toxins, drugs and poisons affect them. Organ models like these are rapidly replacing animals for many lab experiments. But are the days of the petri dish also numbered, as computer models, like the virtual physiological human, become more powerful. We talk to scientists using and developing all three. Plus, a new coating stops joint replacements loosening, magnetic therapy for strokes, and plants do long division... Like this podcast? Please help us by supporting the Naked Scientists

Fungi go under the microscope this week as we explore how they barter minerals and carry chemical messages in return for sugars from plants; we also hear from someone who nearly died after consuming a deadly fungus, find out why fungi make the toxins they do, and hear how these organisms might hold the key to the next generation of packaging and building materials - and even surfboards! Plus, news of a light-powered retinal implant to restore sight, whether alcohol is dangerous in pregnancy, and why aspirin prevents cancers... Like this podcast?
