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.

    Average Americans will never see this. This comes at a time when regulations are being removed and meat packers are shooting up beef with red die to make it not look bad and rotten fish is being treated with CO and dies to be sold as fresh fish…

    Cool cool.

    leans forward

    Now, can it also not persist in the environment for 1000 years after the thing it was packaging has been unpackaged?

      Sure, but only if it instead gives people a type of incurable cancer in about 30 years.

              I’m sorry faceless downvoters, my bad. My morality was compromised.

              AI is terrible and everyone hates it because they exploit a large database of unlicensed copyrighted works to generate images for profit

              Memegen site images are a better because they exploit a large database of unlicensed copyrighted works to generate images for profit but have been doing it for longer, so it’s fine.

    They’re going to make this way too sensitive so people throw away even more food and effective prices get driven up. I guarantee it

    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.

    I’ve had a number of occasions where I purchased meat and it was spoiled before the expiration date. At this point, I’m sick of putting my trust in big corporations and am trying to buy more foods produced locally.

      No matter where you buy it, expiration dates are only a general guide, and more of a “date of manufacture” note than anything. We evolved to detect potential food that has gone bad. Trust your senses. Look and smell should be enough to know what’s actually gone bad (which is usually past the “expiration” date). You can use something like this as a better guide for when food will actually go bad, but, again, trust your senses.

        I was buying it at Kroger, but got tired of meat being expired the first day I got it home, long before the expiration date. Now I buy from a rancher down the road. Re-reading my comment, it may have been unclear that I’m buying local to get better quality than I can get from big corporations.

    I have an extremely simple solution for this made-up problem : Just don’t eat meat 🤷🏻‍♀️

    What are you, a tiger ? No ? Then why do you put yourself through this, when it only makes you sicker the more you do it ?

      Humans are not herbivores. There are a lot of good social and ethical reasons to not eat meat, this is not one of them.

        Humans may not be obligate herbivores ; nonetheless eating meat invariably hurts us in the short and long term.

        Meet is like alcohol, you can get your calories from booze ; but why would you inflict that upon yourself ?

        Eating meat is only deleterious. You may be able to stave off the visible consequences for a while, but make no mistake, it is eating you from the inside.

        We were not meant to feed upon murder.

        Proof ? Vegans are the only human group to be consistently healthy and long lived. We are exempt from many illnesses considered nigh-inevitable, even when genetically predisposed.
