In this paper we present the summary of recent experimental results obtained by the FOPI Collaboration at GSI/Darmstadt, Germany. The baryon rapidity distributions in isospin symmetric and asymmetric nuclear collisions demonstrate incomplete mixing and partial transparency of the projectile and target nuclei at SIS energies. In the analysis of the baryon sideward flow at incident beam energy of 0.4A GeV, a soft Equation-of-State with momentum dependent interaction in the IQMD model is the only parametrization that reproduces the data. The transverse momentum dependences of the K+ sideward flow and the ratio of K- /K+ yields favour the existence of the in-medium repulsive and attractive potentials for K + and K-, respectively.
