Lean in to a glass of champagne and you'll hear a soft chorus of sound as the bubbles pop. Recently, researchers determined the specific mechanism in the process that's responsible for that audible sound. (Image credit: L. Lyshøj; research credit: M. Poujol et al.) Read the full article

Leidenfrost drops slide almost frictionlessly on a layer of their own vapor, generated by extremely hot surfaces nearby. But in this experiment researchers recreated many of the classic behaviors of a levitating Leidenfrost drop without the added heat. (Image and research credit: D.

Carbonation and the fizzy bubbles that come with it are surprisingly popular among humans. (Image credit: D. Cook; see also R. Zenit and J. Rodríguez-Rodríguez; via Jennifer O.)

When you enjoy the sound of a babbling stream on a hike, what you’re actually hearing is bubbling. Air bubbles caught in the water resonate at a frequency that depends on their size. In fact, you can use a hydrophone -- basically an underwater microphone -- to listen to these bubbles and learn about them. Researchers recently did exactly that with glasses of sparkling wine. By listening to the bubbles and applying a simple physical model, the researchers could characterize differences in two brands of sparkling wine, including just how bubbly they were and what size their typical bubbles are. They hope eventually to develop acoustic techniques that can monitor quality control for sparkling wines and other carbonated beverages. (Image credit: J. Kääriäinen; research credit: K.

Dates unclear, but certainly between. 2006-2012.
