Also, what the meteorite strike that wiped the dinosaurs out would've been like; and why co2 isn't the only greenhouse gas we should be worried about.

It sits at the bottom of the periodic table of elements, among its fellow radioactive substances, including uranium and plutonium.  It’s called Thorium, named for the Norse god of thunder. Decades ago, uranium won out over thorium as the nuclear fuel of choice to power the world’s reactors. A new book makes the argument that it’s high time to revisit thorium as a way to wean ourselves off fossil fuels and deliver a safe energy source for the future. Co-host Susan Moran interviews the author, Richard Martin, a journalist and editorial director at Pike Research in Boulder. The book is called"Superfuel: Thorium, the Green Energy Source for the Future." Space Weather (start time 13:15). It has been said that "You don't need a weatherman to know which way the wind blows."  However, you DO need a weather satellite and space researchers to know which way the solar wind blows, and if that solar wind will affect anything orbiting or on the Earth.  So, today How On Earth co-host Joel Parker talks with Space Weatherman Joe Kunches, at NOAA’s National Weather Service, Space Weather Prediction Center in Boulder, Colo., to explain the Sun-Earth connection and why we should care about space weather forecasts.  Kunches is a space scientist. Formerly he was Secretary of the International Space Environment Service.  Kunches says he is in his fifth solar cycle in the space weather field.

This week, we follow a novel alloy from PC to plane, finding out how computer modelling and design can help us create new metals with exciting new properties. We also discover how these newly-designed metals are forged, treated and tested before they form the basis of a new generation of jet engines. In the news, deep-sea dwelling bacteria that are still digesting a meal dating from the time of the dinosaurs, a shot-in the arm for ageing satellites and a brain-interface device to permit paralysed patients to control robotic arms...

Is their power truly still as strong today?

Plus we ask can we make a magnet so strong that is squashes, rather thanks sticks to, our white goods?
