London, July 17 (ANI): Scientists have been able to make a 123-year-old talking doll made by Thomas Edison sing 'Twinkle, Twinkle, Little Star' once again.
For more than four decades, it lay in the bottom of a secretary's desk drawer, its purpose unknown.
But now, the secret of this bent metal ring, which was found in Edison's laboratory, has finally been uncovered, reports the Daily Mail.
Using modern technology, scientists extracted sounds embedded in the small, bent metal ring and recovered what is believed to be the earliest known voice for a talking doll, a venture at which Edison eventually failed.
"It was clear from looking under the microscope that it had a sound recording on it. Phonograph grooves have a familiar shape," said Jerry Fabris, a museum curator with the National Park Service.
But the metal ring - about 2.5 inches around and half an inch wide - was so bent and damaged that scientists couldn't play it.
In 2009, scientists at the Lawrence Berkeley National Laboratory in Berkeley, California, used image analysis to create a digital model of the record's surface.
That model was then used to reproduce the recording as a digital file, not unlike the modern technology behind the voice that emerges from today's talking dolls. (ANI)
