Description
I review the recent construction of a family of new twistor string theories which are
free from world-sheet anomalies and give the space-time spectra of Einstein
supergravities, with second order field equations, instead of the higher derivative
conformal supergravities that arose from earlier twistor strings. I then discuss the
calculation of gauge theory and gravity amplitudes in the new theories.
