Doctors and researchers at Stanford University have created an AI tool that could dramatically boost the efficiency of organ transplants. The model predicts whether a donor will die within the crucial timeframe needed to preserve organ quality, cutting wasted preparations by 60%. Trained on data from more than 2,000 donors, the tool outperforms top surgeons and helps ensure that more viable livers reach patients. The breakthrough could ease pressure on transplant teams and give more people a chance at life.

An international society for cryptographers had to scrap its committee election after they were unable to decipher the results. Members of the International Association of Cryptologic Research used a “secret digital ballot whose final tally could be decoded only by using three keys split among select election trustees,” said The New York Times. But one of the trustees misplaced his key, leaving organizers “with no choice but to throw out the vote and call a new election.”
