Since 1993, the International Atomic Energy Agency has tracked 2,500 trafficking cases of nuclear material. While there has yet to be a detonation of a dirty bomb, the threat remains present. In the unlikely event of a nuclear attack on American soil, Notre Dame engineering professor Antonio Simonetti makes one thing clear: The perpetrator could and would be found.Simonetti is a geochemist who specializes in characterizing the chemical and isotopic composition of materials. Traditionally, that involves studying rocks and minerals, which Simonetti did for many years. In 2011 he pivoted to assess nuclear materials like trinitite at the request of National Nuclear Security Agency. In that role, he used laser ablation-inductively coupled plasma mass spectrometry (ICP-MS) to study blast melt from the first atomic bomb test in New Mexico in 1945 and precisely identified where remnants of plutonium fuel resided after the explosion.More: http://ntrda.me/FTProtectOurCountry

- 2:01Fighting for the Lives of ChildrenWhen your child is diagnosed with a rare, genetic disease, it feels like you’re rolling down a mountain, just waiting to hit rock bottom, says Doug Berns. When his daughter, Samantha, was diagnosed with Niemann-Pick Type C, an incurable, neurodegenerative disorder, he and his wife watched as Samantha’s energy depleted, her balance became shaky, and her laughter quieted.At Notre Dame, researchers in the Boler-Parseghian Center for Rare and Neglected Diseases seek to identify and advance treatments for a number of rare diseases, including Niemann-Pick Type C.For more information: http://ntrda.me/LivesofChildren
- 2:01Fighting to Walk AgainPerhaps no greater motivation exists in this world than hope. For the 450,000 Americans with spinal cord injuries, the hope that they can regain mobility, walk again, run again is often what pushes them through each therapy session. But those same patients often plateau in their recovery, and hope dwindles.Though he’s not a physician or physical therapist, Notre Dame engineering professor Jim Schmiedeler’s work may contribute to better success for these patients. In his locomotion and biomechanics lab, he uses tools from his biped robotics research to better understand the challenges spinal cord injuries present for those learning to walk again. By partnering with researchers at The Ohio State University, Schmiedeler can also test how lessons learned from experiments with the robots, which involve no risk to humans, can be translated into innovative therapeutic strategies that benefit patients. In doing so, he believes his work can help many of those individuals with a spinal cord injury to walk again.Read More: http://ntrda.me/WalkAgain
