In this work we study a brane world model with variable tension, which gives rise to four-dimensional cosmologies. The brane worlds obtained correspond to Eötvös branes whose (internal) geometry can be casted as either a four-dimensional (A)dS4 or a standard radiation period cosmology. The matter dominated period is discussed as well.
