Abstract: Affirmative answers are given to the following two questions about the Weyl algebras: a question of J. Alev: Does the first Weyl algebra contain a non-noetherian subalgebra?, and a question of T. Lenagan: Is there a uniserial module $M$ of length $2$ over the Weyl algebra $A_n$ with a holonomic submodule $U$ such that $V=M/U$ is non-holonomic?
