The study also reports the first scientific evidence confirming the importance of chilling champagne before serving to enhance its taste, the scientists say. Their report appears in ACS' bi-weekly Journal of Agricultural and Food Chemistry.
Gérard Liger-Belair and colleagues note that tiny bubbles are the essence of fine champagnes and sparkling wines. Past studies indicate that the bubbles — formed during the release of large amounts of dissolved carbon dioxide gas — help transfer the taste, aroma, and mouth-feel of champagne. Scientists long have suspected that the act of pouring a glass of bubbly could have a big impact on gas levels in champagne and its quality. Until now, however, no scientific study had been done.
The scientists studied carbon dioxide loss in champagne using two different pouring methods. One involved pouring champagne straight down the middle of a glass. The other involved pouring champagne down the side of an angled glass. They found that pouring champagne down the side preserved up to twice as much carbon dioxide in champagne than pouring down the middle — probably because the angled method was gentler. They also showed that cooler champagne temperatures (ideally, 39 degrees Fahrenheit) help reduce carbon dioxide loss.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
