<p>On this week’s show: Meta’s algorithm tackles both language and strategy in a board game, and measuring how much water people use on a daily basis</p> <p>First up this week on the podcast, artificial intelligence (AI) <a href="https://www.science.org/doi/10.1126/science.adf9357">wins at the game Diplomacy</a>. Freelance science journalist <a href="http://www.magicalthinkingbook.com/author/">Matthew Hutson</a> joins host Sarah Crespi to talk about the advances needed for an AI to win a game that requires cooperation and trust between human and AI players.</p> <p>Next, we hear about <a href="https://www.science.org/doi/10.1126/science.abm8668">how much water people need to stay hydrated</a>. It’s not the eight glasses a day recommendation we’ve heard so much about. <a href="https://sites.duke.edu/pontzerlab/people/">Herman Pontzer</a>, a professor in Duke University’s Department of Evolutionary Anthropology and the Duke Global Health Institute, talks about a study that involved recording water turnover from 5000 people around the world.
