This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

Just post some stuff and don't spam.

In Norway, laser weapons are being used to remove sea lice from farmed salmon. The Stingray Laser System uses cameras to scan the fish, identify lice, and then deliver a laser pulse to kill them. (files.catbox.moe)
