'The War on Terror' is pretty much an everyday phrase and many of us glaze over when we hear it. But here's an interesting tidbit: The government has researchers looking into the development of a Human Scent Collector. The device will be used to collect human scent from suspected terrorists which can then be stored and used to track the suspect.
Implications - The idea comes from the Technical Support Working Group (TSWG) who is trying to make this possible. There are existing technology similar to what this project is trying to be achieved; however, it's claimed to be too large and fragile in an operational environment. The plan is to make a handheld device so that portability isn't an issue.
