TL;DR

Researchers used a functional-connections-based method to simulate 30 million Earth–Moon routes and found a previously hidden gravity-assisted trajectory that saves about 58.8 m/s of delta-v over the prior cheapest path, enabling cheaper Moon travel and uninterrupted Earth communication; further work could include solar gravity to push costs even lower.
