Spectra obtained with VLT/UVES suggest the existence of the Li isotope in several metal-poor stars at a level that challenges ideas about its synthesis. The Li abundance is, on the other hand, a factor of three lower than predicted by standard Big Bang nucleosynthesis theory. Both problems may be explained if decaying supersymmetric particles affect the synthesis of light elements in the Big Bang.
