Irène Joliot-Curie and Artificial Radioactivity

When Marie and Pierre Curie discovered the natural radioactive elements polonium and radium, they did something truly remarkable– they uncovered an entirely new property of matter. The Curies’ work was the key to unlocking the mysteries of the atom, which was previously thought to be indivisible. Their research opened the door to nuclear medicine and clean energy, and it also led to the development of nuclear weapons.

Irène Joliot-Curie, her husband Frédéric, and many of their contemporaries were completely against the use of nuclear science as a weapon. They risked their lives to guard their work from governments hell-bent on …read more

The truth is, antimatter is a little less exotic than it appears on TV, but for a variety of reasons there hasn’t been nearly as much practical research done with it. There are well over 200 electron accelerators in labs around the world, but only a handful that work with positrons, the electron’s anti-counterpart. [Dr. Aakash Sahai] would like to change that. He’s got a new design that could bring antimatter beams out of the lab and onto the desktop. …read more
