Smell you later

So far, cell phones have been able to handle three of the five senses — seeing for the blind, listening to music and identifying the song and vibrating to let us know that we have a call or text message. Soon, a fourth sense may be added to that list: smell.

The U.S. Department of Homeland Security is funding research that will allow cell phones to “sniff out” poisonous gasses and alert users to potentially deadly smells.

In a few years, who knows — maybe your phone will be able to smell the best pizza in town and direct you to it.
