'Probably' doesn't mean the same thing to your AI as it does to you
When a human says an event is "probable" or "likely," people generally have a shared, if fuzzy, understanding of what that means. But when an AI chatbot like ChatGPT uses the same word, it's not assessing the odds the way ...

A heatshield for 'never-wet' surfaces: Engineers repel even near-boiling water with low-cost, scalable coating
Superhydrophobic surfaces—those famously "never-wet" materials that make water bead up and roll away—have a stubborn weakness: hot water. Once temperatures climb above roughly 40 degrees Celsius, many superhydrophobic ...

Engineers discover new physics principle to break sound absorption barriers in ventilated spaces
In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it hard to reduce noise ...
