<ul><li>A research team led by scientists from Tokyo Metropolitan University utilized a new technique to set limits on the lifetime of Dark Matter (DM).</li><li>The team's investigation focused on axion-like particles (ALPs) and their decay process, which emits light in the near-infrared part of the spectrum.</li><li>Using a spectrographic technique, the researchers observed light from two dwarf galaxies and found no decay, setting stringent limits on the frequency of decay events or the lifetime of ALPs.</li><li>The results provide new insights but also present tantalizing prospects for future investigations in the search for Dark Matter.</li></ul>
