On a sunny day near Martinez, California, a friendly-looking German shepherd named Zinka rushes down the crisscrossing trails of Briones Regional Park wearing a vest covered in sensors, batteries and wires. She’s followed by her trainer, Shay Cook, who keeps up at the end of a long leash.
“It's a treat to go out and watch a search and rescue dog work a trail and see them find the person at the end,” said Judy Jinn, a doctoral candidate in theJinn is wrapping up a study that seeks to shed some light on the surprisingly complex question of how dogs can track a target using tiny amounts of odor that people don’t even notice.
In the experiment, the target hiker would get a one-hour head start — although Zinka can track people even days later. Even rain doesn’t stop her keen sense of smell. Then the researchers run different computer programs that inspect the model for the source of the plume. Crimaldi wants to know which algorithms do a better job of locating the source of the odor within the model.
While working at Penn State University, Brent Craven and his colleagues looked at the anatomy of a dog’s nose, and how air moves through it. The Penn State University researchers used data from the scans to create a computer model that mimics the anatomy of the dog's nose, inside and out.
KQED So we as humans can pick up the scent of a crappy politician faster?
KQED Trust me, your dog knows he farted, he just doesn’t care
KQED ...and if your dog follows you to the bathroom... Well, then, that must be extreme loyalty - right, truTVjokers , SalVulcano , Joe_Gatto , BQQuinn , JerrySeinfeld , JimGaffigan ?

KQED BrendanSchaub wants to squeeze that dog nose
KQED Maybe it has something to do with the fact that they have a lot more real estate for olfactory nerves ... and also they dedicate more neurons to the task.

KQED The nose knows.
KQED All the better to find the cat poop/snack

KQED So why do they have to stick their nose right up you butt. That is the question I wast science to answer
KQED gross
KQED My Cocker/Lab cross could find arrows buried beneath the grass. Once he ranged too far and was lost on a hunting trip. I left my hunting jacket where I last saw him. Next morning he was sleeping on my coat.
KQED Dogs are so cool...
KQED (Hint: their noses.)
