"Isotope separation, Maxwell’s demon, and the Pointsman Foundation"

Abstract: The separation of atomic isotopes is a long-standing challenge, due to the very small differences in their physical and chemical properties. The main method of separation, the Calutron, was invented by Ernest Lawrence over 80 years ago, and is still used today. Motivated by the thought experiment of Maxwell’s demon, we developed a new and efficient method of isotope separation. Magnetically activated and guided isotope separation (MAGIS) relies on optical pumping and magnetic forces, and is much more efficient than the Calutron. This work is now being pursued at a non-profit entity, the Pointsman Foundation, where we are enriching isotopes for medicine. There is great promise in targeted therapy of cancer using radio-isotopes attached to targeting agents. Stable rare isotopes of essential minerals can be used to determine their optimum absorption in the body, a method pioneered by Pointsman Board member and pediatrician Steven Abrams. We will apply our methods to prevent iron deficiency, which affects over 2 billion people in the world, and 50% of all children. The Pointsman Foundation is working with medical researchers and companies on advancing applications of isotopes to benefit humanity.
