Scientists designed color-changing carbon dot biosensors that can detect spoiled meat in sealed packages in real-time, just in case you don't trust the sniff-test.

As a negative control, they also prepared an identical sealed tray containing only a wet sponge and the biosensor, but no meat. They observed that the biosensors in the pork and mutton trays turned bright yellow after 24 hours, while the one in the beef tray took 36 hours. In contrast, the control biosensor showed no detectable change.

That's so cool, meat is still gross, but this is unambiguously a fantastic thing for humanity. If it's actually used, I'd have to imagine the less reliable yet ass covering legal expiration date sticker will always be cheaper. Hope this becomes the new mandated standard, innovations are meaningless in the face of uncaring capitalism.
