Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. The soap bubble with its delicate, fragile skin tells us about how nature works on scales as large as solar system and as small as a single wavelength of light. Then there are underwater bubbles, which matter because they are part of the how the planet works. Out at sea, breaking waves generate huge plumes of bubbles which help the oceans breathe. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it's the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.

In this episode of NOVA scienceNOW, journey back in time to the birth of our solar system to examine whether the key to our planet's existence might have been the explosive shockwave of an ancient supernova. Meet a chemist who has yielded a new kind of "recipe" for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that's been sucking our blood for millions of years, is offering clues about our evolution. Finally, meet neuroscientist André Fenton, who is looking into erasing painful memories with an injection.
