  The main goal of the REM project is the observation of prompt afterglow of
Gamma-Ray Burst (GRB) events. Such observations at Near InfraRed (NIR)
wavelengths are even very promising, since they allow to monitor high-z
Ly-$\alpha$ absorbed bursts as well as events occurring in dusty star-forming
regions. In addition to GRB science, a large amount of time ($\sim 40%$) will
be available for different scientific targets: among these the study of
variability of stellar objects open exciting new perspectives.
