Systems engineering researchers have developed a new technique to improve the efficiency of food-delivery operations. The technique accounts for the location of food distribution sites and delivery locations to develop optimized delivery routes that make food delivery faster and more fuel efficient.

Two seemingly opposite spiritual practices – Buddhist jhāna meditation and the Christian practice of speaking in tongues – have more in common than previously thought, a new study suggests.

While one is quiet and deeply focused, and the other emotionally charged and expressive, both appear to harness the same cognitive feedback loop to create profound states of joy and surrender.
