Interesting article from the recent NASA Tech Briefs about the possibility of equipping cell phones with sensors to detect biological attacks (along with other things). Now that's a concept that fits right into a story somewhere.

CELL PHONE SENSORS
The Department of Homeland Security (DHS) is researching the use of cell phones
equipped with sensors that could detect biological agents such as anthrax,
as well as radioactive isotopes and toxic chemicals. Since fixed sensors
can't be placed everywhere, the solution could soon be in everyone's hands.
Gentag, a Washington, DC-based company, is working with the government on
a patented technology that modifies a cell phone to serve as a low-cost
radiation and/or chemical sensor to discover external threats. The technology
incorporates both modular (removable) sensor modules and built-in sensors.
The DHS program, called Cell-All, would link cell phones equipped with the
detection sensors via the Global Positioning System (GPS). If a detector
sensed a threat, the GPS would transmit the location and time to local
emergency responders and the DHS operations center. According to the DHS, if
the program works, it could be a "game-changer" in how the nation detects and
responds to a deadly attack.
