A University of Missouri professor has resurrected his two-decade-old work in the contested field of cold fusion. In 1991, Mark Prelas was part of a research team that conducted a fusion experiment that emitted a burst of millions of neutrons. The work stopped when funding was cut off. At the time, cold fusion claims had been dismissed as junk science. Prelas shifted to other work. But his neutron-producing experiment resumed this year, and he presented his findings at a cold fusion conference in August in South Korea. Prelas, now a professor in the university's Nuclear Science and Engineering Institute, received funding from the Sidney Kimmel Institute for Nuclear Renaissance at MU. In the original experiment, the team created an emitted neutron-recording device and expected to count about 10 neutrons a second. They reached a million neutrons in a second. With SKINR funding, [Prelas] re-created the experiment. More technologically advanced equipment has allowed for a better counting system, and in one run, his research team saw neutron emissions at similar levels to the 1991 observation. Rob Duncan, MU's vice chancellor of research, said ... We've got to understand what this is. The focus clearly has to be on an opportunity to discover new physics and to understand new science. That really is our aim here at SKINR."
