The walls are alive… with sophisticated sensors that can sniff out potential terrorists, according to Popular Science:
Researchers at brain trust Fraunhofer Institute for Communication, Information Processing andErgonomics (FKIE) in Wachtberg, Germany have developed a network of “chemical noses” that can not only smell chemicals hidden on a person, but also identify the carrier as he or she moves through a crowded space.
This means that someone entering an airport with individual chemical components, that can be used to make an explosive later, can be tracked right from the door itself.
Sensitive sensors located in walls would “sniff” out the chemicals, triggering a discreet security alarm. The sequence of triggered alarms would allow security personnel to determine which direction the chemical-carrying person was moving, and a software program would zoom in on one individual in the crowd. Cameras all over the airport would track the suspect as he moves and security could then apprehend the person well before he/she reaches the crowded security checkpoints.
A Singaporean man trying to enter the U.S. was detained by TSA officials for four hours as a possible security threat, all because he had no fingerprints. Turns out he wasn’t a potential terrorist—he just had cancer. Experts point to capecitabine, a drug he was taking to prevent a recurrence of his head and neck cancer, as the reason for the fingerprint loss.
One of the side effects of capecitabine, which is a common treatment for breast, head and neck, and stomach cancers, is a disorder known as hand-foot syndrome. The disease causes the skin on the palms of the hands and soles of the feet to swell, peel, and bleed.
In the near future, every American will have a digital avatar made with real life census data, to help predict the spread of infectious diseases. But what about when we’re traveling? Jared Diamond holds that air travel can hastened the spread of pandemics all over the world. Enter a Belgian company called Biorics , which has developed a device that can reportedly enable airport security to tell whether someone is carrying a pandemic virus by the sound of their cough.
The company’s plan is to place multiple microphones in the waiting areas of airports, and then process the sound to get rid of background noise. By singling out cough sounds from regular cell phone conversations and airport chatter, the device can supposedly tell if a person is just clearing their throat, or if they have a cough that indicates they are infected with a virus. The loudness of the cough would help authorities locate the sick person.
The idea has some merit: It’s quick and simple, and could potentially prevent substantial harms. Of course, if the detector makes a mistake, you might find yourself quarantined at JFK after choking on a bottle of water.
