Advances in artificial intelligence, specifically reinforcement learning, are proving beneficial to accelerating the pace of data-intensive challenges. The methods used by researchers with RL are techniques often used in video games, and by applying gamification to scientific processes, RL agents can learn as they are used in experiments, in effect, leveling up their rates of discovery as they work. Researchers are using trained RL agents at NSLS-II to accelerate the analysis of data-heavy measurements.

Sodium-ion batteries offer several advantages over lithium-ion batteries; however, it is difficult to develop sodium cathodes, materials through which electrons can enter a battery. Many candidate materials are unstable or cannot withstand high voltages. To find a solution, researchers turned to nature. They created a porous system of NVP structures, surrounded by a dense shell of reduced graphene oxide. They describe the mammal bone-inspired sodium cathode in the journal Applied Physics Reviews.
