Beer-slinging robot predicts whether you'll give that brew a thumbs up--or down

As we pawn more and more jobs off on robots, there are a few you'd think we'd keep for ourselves, like beer taster. But brewers often need an automated way to ensure product quality, and a research team in Australia has developed a cheap method to help them. Their latest study assesses a freshly poured beer's frothy top. Why focus on the bubbles? Because foam affects people's enjoyment of beer and sparkling wine even more than taste and aroma do.
