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.

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

[-] CovfefeKills@lemmy.world 4 points 6 days ago

After they are legally mandated to use it because selling spoiled meat is profitable.

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...

I've got a fairly reliable tool that does the same, I keep it in the middle of my face

Anosmia is more common than you might think. A lot of stuff that seems silly on the face of it is hella useful for people with disabilities.

Noses do seem silly on the face of anosmics.

[-] ebolapie@lemmy.world 5 points 6 days ago

I really walked into that one huh

[-] isVeryLoud@lemmy.ca 5 points 6 days ago

Sure smells like it!

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?

But what does the scouter say about his power level, Vegeta?

Someone AI a gif of this STAT

[-] Sturgist@lemmy.ca 3 points 5 days ago

No. Here's a memegen though?

[-] FauxLiving@lemmy.world 1 points 5 days ago

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.

[-] Sturgist@lemmy.ca 1 points 4 days ago

Both can be bad. These aren't mutually exclusive.

[-] Abrinoxus 4 points 6 days ago

[-] MBech@feddit.dk 5 points 5 days ago

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

Won't that affect Walmarts profits? 🙃

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.
