The $25,000 Wolfram 2,3 Turing Machine Research Prize has been won.

Alex Smith, a 20-year-old undergraduate in Birmingham, UK, has
given a 40-page proof that Wolfram's 2,3 Turing machine is indeed
universal.

This result ends a half-century quest to find the simplest
possible universal Turing machine.

It also provides strong further evidence for Wolfram's Principle
of Computational Equivalence.

The official prize ceremony is planned for November at Bletchley
Park, UK, site of Alan Turing's wartime work.
