Pigeons navigate using magnetic sensors in livers — study

Reply in thread

Per the article, they didn't remove the livers, only depleted the macrophages:

"We found that after macrophage depletion, pigeons flying under overcast conditions lacked their usual orientation capabilities," they said.

Also:

When the sun was visible, the birds' orientation was unimpaired, suggesting that visual and solar-based cues were another of the pigeons' navigation methods.

At Seoul's bridge control center, AI helps stop 99% of suicide attempts

Oops, my bad for didn't read the whole article.

Still, the technology has its weaknesses. Kim said the system carries a hallucination rate of about 15 percent, including instances where it misidentifies an object as a person, which is why human judgment remains the final call.

The AI only flagged the people (or the objects it misidentified as people), but the human still decides whether those people are worth checking on. I think it still the human's fault if a lot of innocent people get harrassed by the police.

They also had already deployed soldiers to put traps and allowed the police to shoot and kill bears when necessary.
