Inventor Thomas Edison is known for being ahead of his time, and a new study could add another notch to his overachieving belt. Researchers at Rice University suggest Edison may have inadvertently created graphene in 1879 – a "wonder material" that wasn't officially made until 125 years later. But according to the new research, they might have been beaten to the punch by Edison – though he wouldn't have noticed. To test whether Edison may have unwittingly created graphene during early testing of his stable light bulbs, the Rice team sourced similar-styled bulbs, complete with carbon-rich bamboo filaments. Even if Edison had realized what he'd made, graphene probably wouldn't have been much use to him at that point in history.
