This is known to be sensitive to possible strange-quark contributions to the nucleon spin. Recent 3D simulations suggested that a large enough strangeness contribution can successfully produce explosions. This paper examines theoretical and experimental progress over the past decade and concludes that the strangeness contribution is very small. Hence, the search for the elusive mechanism to explain core-collapse supernovae must continue.
