Researchers in the US have uncovered evidence suggesting that Thomas Edison may have accidentally produced graphene over a century before it was formally identified, while developing his first light ...

In Livermore, California, a remarkable light bulb has defied the odds for over a century. Known as the Centennial Light, this carbon-filament bulb has been glowing since 1901, earning it the title of ...

The folks at Sengled brought a very vintage-looking piece of tech to Las Vegas this week, to CES 2020. This is the Sengled Smart LED Edison Filament Bulb, with a design that's decidedly old-school.

What do Thomas Edison and Nobel Prize in physics winners Konstantin Novoselov and Andre Geim have in common? According to a recent publication from the lab of Rice University’s James Tour, it could be ...

Early carbon light bulbs may have produced graphene, since applying voltage to carbon filaments mirrors what is now called flash Joule heating. Graphene is a transparent, remarkably strong substance, ...

Researchers create a prototype bulb with a carbon nanotube in place of the standard tungsten filament. It uses less power, burns brighter and could lead to the first major overhaul in bulb design in a ...
