Good News in the Future?

This is fascinating to me. They have been able to train dogs to sniff out Covid 19. AND, the results are as good (probably better in many cases) than actual tests.

You can read the entire article, there are a lot of diseases that dogs can smell already. Actually I have read (elsewhere) that dogs are fantastic at sniffing out some cancers (like prostrate) from samples - but it is super boring work and dogs don't like it. Because they have to be in a lab, and just sniff those of beakers over and over.

Right now the have proven it with urine samples, but if they can get dogs to sniff people and find out- then they could use them at airports just like drug sniffing dogs. That would be great.
