I envision a beautifully colorful potato salad utilizing multiple colors of potatoes. But would a cooked mixture be like carrots with potatoes (minimal bleed) or like beets with anything else (maximum bleed)? Lorraine BauderSudbury, Mass. The red and blue pigments in the new potato lines are “water soluble and will leach,” notes USDA’s Charles R. […]

This article mentions “ferricyanide, an electron-hungry molecule.” This puzzled me no end. Aren’t ferricyanide molecules, unlike their ions, electrically neutral? I’m trying to visualize ravenous molecules gobbling up innocent electrons. Ernest NussbaumBethesda, Md. Ferricyanide is indeed an ion, with a negative charge of –3. It’s electron hungry because, counterintuitively, it draws an electron from the […]

Your article reports that between 1973 and 1999, “the total area covered by almost 940 Swiss glaciers fell by 18 percent, an average rate of 1.3 percent per year.” An 18 percent loss over 26 years represents an annual rate of less than 0.8 percent. An annual loss of 1.3 percent would mean a total […]

It seems interesting that undersea flows have at least one characteristic different from rivers: “While river floods on land can create natural levees a few meters tall, the levees formed by [undersea] turbidity currents can grow up to 100 m[eters] high.” There are several sites on Mars where channels with loops can be seen. Although […]
