The Burt controversy has taken a number of strange twists and turns, leading many observers to conclude that he has been exonerated of the accusation that he fabricated his data on monozygotic twins reared apart.

Biologic effects of supernovae.
Estimates of the probability that nearby explosions of supernovae have occurred during the earth's history and the biologic effects of the radiation therefrom are presented. They suggest that cosmic radiation from supernovae could have caused the extinction of many exposed animals without the simultaneous extinction of plant life. This suggests that supernovae should be considered as one possible mechanism by which fauna become extinct.
