Has the headline been changed since you commented?

The headline on HN at the moment is "As Alaska's salmon plummet, scientists home in on the killer". The headline on the article itself is "As salmon in Alaska plummet, scientists home in on a killer". I don't see any way to read those as suggesting science is killed the salmon.

I was intrigued because I genuinely thought that’s what it said.

It's not? Industrialization, pollution, and climate change are downstream effects of science.

Yeah this should seriously be re-titled lmao

If you continue just a little bit, when you get to the source, it should make things more clear. Considering the source is important, as is reading the article!
