AI Just Uncovered a Hidden Secret Inside Water
Researchers at the University of Osaka are using artificial intelligence to study the molecular structure of supercooled water. The AI framework helps explain why water behaves uniquely, particularly its tendency to expand when freezing and its transition between high and low-density liquid states.
Why it matters
Understanding the fundamental properties of water at a molecular level has broad implications for chemistry, physics, and materials science.
AI is helping scientists uncover the hidden molecular structure behind water's famously strange behavior.
Water covers most of Earth's surface, yet it continues to puzzle scientists because it behaves differently from almost every other liquid. One of its best-known quirks is that it expands instead of shrinking when it freezes. Researchers have long connected these unusual properties to changes in water's microscopic structure as temperature and pressure vary, but they have lacked a consistent way to measure and compare those structural changes.
Now, a team at the University of Osaka has turned to artificial intelligence (AI) to tackle that challenge. Their study, published in Communications Chemistry , introduces an AI-based framework that evaluates and compares different ways of describing the structure of supercooled water.
