Why is that whenever a woman (be it a scientist, politician or any other profession) achieves something, the gender is always mentioned in the headline. E.g. If she had single handedly caught the biggest smuggler, the headline would be "Female executive director of San Jose police union blah blah blah". But when it's something like this, the gender is often omitted.
