It’s soooo cute! Look at the widdle wight buwb! Aw, New Scientist, if that tiny lamp isn’t the cutest thing ever!:

Chris Regan’s team at the University of California, Los Angeles attached a palladium and gold electrode to each end of the carbon nanotube, which spans a tiny hole in a silicon chip and is held in a vacuum.

Using it, the team will investigate Planck’s black-body-radiation law – a century-old theory that predicted how much light would be emitted from a source by assuming energy was released in discrete packets, or quanta. Planck’s work underpinned the development of quantum mechanics later in the century.

Could its little photons be more random? Nope, they probably couldn’t!
