Sure, we've got fairly sophisticated methods of curbing asthma attacks, but a new pocketable device could hold the key to unlocking more about the relationship between "asthma symptoms and the air a sufferer breathes." Reportedly, this device could allow researchers to look back after an attack has occurred and see exactly what was happening environmentally beforehand. Gurus at the Georgia Tech Research Institute have already been able to help one individual out, as they discovered a "pollutant pathway" from the volunteer's basement into the living room that was allowing vehicle exhaust and gasoline fumes to infiltrate the house. From here, the creators are hoping to downsize the device even further and make it more sensitive, but we've no idea if the current iteration will ever be used commercially.
