A clarification on the story headlined “Scientists edit chicken genes to make them resistant to bird flu” (some editions, June 4, 2019): The penultimate paragraph had referred to a 2009 pandemic caused by H1N1. That entire paragraph on H1N1 should not have been mentioned as the story is related to bird flu (H5N1).

With reference to the “Between Wickets” column titled “India have the team to win the World Cup, so do at least three others” (May 22, 2019), a reader has pointed out that for the record, England reached only one final (1979) when they hosted the event (from 1975, 1979, 1983 and 1999) and not two as the column said. On two other occasions England made it to the title clash: in 1987 (Kolkata) and in 1992 (Melbourne). The reader is right.
