...Using first grape juice and then wine as their test samples, Jonquera-Jiménez and her team attached a series of synthetic membranes to a silicon chip called a microsensor. Each membrane detects a different chemical component of the liquid - components that, when combined, mark the distinct characteristics of each grape varietal. So far, the device can distinguish among four: chardonnay, Aisén, malvasia and macabeu. It can also measure the difference between a 2005 vintage and a 2007.

"It doesn't know how to spell, and can't be taught...
...world-wide media covering Phelps' chase to break Mark Spitz's 1972 Munich record of seven gold medals in a single Games, that means another day at the Water Cube - in Athens, the waiting was over by the second day, when the U.S. men came in third in the 4x100m relay behind South Africa and the Netherlands...
