CORRECTIONS:
The January/February article “Alternative Endings” originally stated that Rich
Roberts and his research group made the finding described in a 1977 paper.
In fact, not all of the paper's authors were members of Roberts's group.
The January/February article “Ohio, Gene Factory” stated that the FDA had
requested more data before allowing a Phase 3 clinical trial of an Abeona
Therapeutics investigational drug to proceed, and that shareholders had filed
a lawsuit against the company for allegedly misleading them. In December
2019, the FDA removed the clinical hold, and according to Abeona, the
shareholders have withdrawn their lawsuit.
The Scientist regrets these errors.
