London, Feb 4 (IANS) Thousands of tiny purple spheres have mysteriously popped up in the middle of America's Arizona desert, completely isolated from the rest of the terrain.
Tuscon residents Geradine Vargas and her husband discovered the strange growth on Sunday during a walk. "We were taking photos around the area and we just ... I mean, how could you miss this?" Geradine said. "It was just like glittering in the sun."
"We did email a friend of ours who's a zoologist, but she didn't know," said a Daily Mail report, quoting Gerardine as having told KGUN-9, a news station in Tuscon. "I mean, she didn't seem to recognise what it was."
The news station checked out the spheres, reporting that they were like "gooey marbles that ooze out a water substance when squished".
Darlene Buhrow, director of marketing for Tucson Botanical Gardens, said that after speaking to a botanist he learned that if the spheres are naturally occurring, they could be a slime mold or jelly fungus.
Others suggest they are some products like Deco Beads which are small, coloured, water-filled balls designed to keep plants hydrated. However, that does little to explain why thousands of them would have been put in the desert.
