Twistor Time
It is very difficult to keep up with arxiv preprints these days, but since kneemo hasn't mentioned it yet, in this new paper Arkani-Hamed et al study the twistor diagrams of Hodges. As the abstract states:
Our twistor transformation is inspired by Witten's, but differs in treating twistor and dual twistor variables more equally. In these variables the three and four-point amplitudes are amazingly simple.They refer in particular to this new paper by Mason and Skinner.

IN his book THE ROAD TO REALITY, Oxford's Roger Penrose promotes Twistor theory while casting doubt on "fashionable theory."
