Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

When the U.S. trade embargo left Cuba isolated from medical resources, Cuban scientists were forced to get creative. Now they've developed lung cancer vaccines that show so much promise, some Americans are defying the embargo and traveling to Cuba for treatment. In an unprecedented move, Cuban researchers are working with U.S. partners to make the medicines more widely available.

Dr. Helen Caldicott is the most prominent anti-nuclear activist in the world. She's been featured on CNN, 60 Minutes, CBC and Democracy Now. In the 80s, Helen Caldicott campaigned against nuclear weapons testing in the pacific (still responsible today for the majority of tritium we're exposed to), and against the notion of a winnable nuclear war. She was nominated for a Nobel Peace Prize for her efforts. She has always made inaccurate statements regarding civilian nuclear power. But, since the Fukushima-Diachii radiation release has caused (and is projected to cause) zero fatalities... http://www.unis.unvienna.org/unis/en/... ...her tone has changed when speaking to supporters. This has not been acknowledged by prime-time media, as they continue to use her as a source. Any person or media outlet should check Caldicott's history of statements (on any subject) against a domain expert before using her as a source.
