This is the first time bacteria have been shown to influence aggression, said corresponding author Jeremy C.

Can autism be measured in a sniff?

Imagine the way you might smell a rose. You'd take a nice big sniff to breathe in the sweet but subtle floral scent. Upon walking into a public restroom, you'd likely do just the opposite--abruptly limiting the flow of air through your nose.

Autistic children go right on sniffing in the same way, no matter how pleasant or awful the scent.
