During the First World War, the British government was looking for ways to help people stretch their limited food supplies. It found pamphlets from a noted 19th-century herbalist who said rhubarb leaves could be used as a vegetable along with the stalks.

Buildings researchers at the Department of Energy's Pacific Northwest National Laboratory have released a new AI-driven, autonomous bot that could help speed up the energy modeling process for commercial building construction. Long before construction begins, commercial building teams evaluate a building's expected energy consumption to inform design decisions, estimate operating costs and comply with relevant state and local energy codes.

Imagine a horse stumbling on a rock. It regains momentum, then hits bumpier terrain and slows to a walk. Back on steady ground, the horse picks up its pace to catch up with the herd. How is the horse able to transition between these different gaits? Researchers at Brown University's Carney Institute for Brain Science have developed an artificial neural network that shows how a four-legged creature may generate multiple distinct patterns in gait. Their research provides new insights into how the brain may process complex behaviors.

A research team from Fraunhofer HNFIZ has published a newly developed evaluation model that classifies the technical capabilities of humanoids into five levels. Applications can also be classified based on the required robot capabilities. The model makes humanoids comparable, facilitates finding the right humanoid for a specific application, and highlights open issues in technology development.

For 150 years, Major League Baseball (MLB) players and fans have accepted that an umpire missing a few balls and strikes is just part of the game. But this spring, MLB is rolling out an artificial intelligence-augmented camera system that will provide a second opinion for players to tap if they think an umpire whiffed.
