Scanner ‘Reads’ Pages Of Closed Books

A variant on X-rays could scan the pages of a closed book according to MIT researchers. Tests already show the technique working on a bundle of nine sheets of paper. The research is detailed in the snappily-titled Nature Communications article “Terahertz time-gated spectral imaging for content extraction through layered structures.” It’s based around using T-rays, […]



Starchiness: A Sixth Taste Discovered?

Starch could be a taste in its own right, newly-published research suggests. Tests found subjects could detect the taste as separate from sweetness in carbohydrate-rich foods. While we can detect countless flavors — each a combination of taste and aroma –, the standard explanation at the moment is that we can only detect five distinct […]

Why Don’t Oil and Water Mix While Salt and Water Does? [Science Video]

Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin’ dance party where the water molecules are always switching dance partners — and they’d much rather dance with a salt ion. John Pollard explains how two chemistry principles, energetics and entropy, rule the dance […]
