When you take your dog for a walk, does he stop to sniff every tree trunk and patch of grass he sees, leaving you to wonder what smells so enticing? Scientists have also wondered, although not the trivial lawn fodder, what pups’ sensitive noses pick up to help detect drugs or disease. Lawrence Livermore National…

While smart home devices have expanded to include speakers, security systems, lights, and thermostats, their control has mostly been limited to a remote, an app, or voice commands. Users can interact with their phones or speak to the technology. Still, these methods are often less convenient than the simple switches they replace, significantly since devices…
