Annalee Newitz of IO9 interviewed Michael Dillon, an atmospheric scientist at the Lawrence Livermore National Laboratory. They focused on Dillon's research about how the government should respond in a disaster scenario where an airborne threat can continue to spread. If you're interested in future scenarios happening after a man-made calamity, this is a great source of information.

Dillon's study on Royal Society A

This year's CES was filled with new wearable technologies looking for the next big thing, but Thinkgeek is selling a tongue-in-cheek wearable as a spidey-sense shirt that vibrates when someone approaches from behind, signaling the wearer a person is within 5 feet.

The device is a novelty, announced just before last year's Comic-Con, but would make great sense as a real wearable or a feature included in a line of self-protection wearables. So much discussion on the benefit of wearables has focused inwards so far. Step tracking or distance measuring was the first real attempt. Tracking body data such as heart rate, blood pressure, blood sugar and such for biorhythm projection is where the current cycle is focused. How long before we focus outward?

Too many future visionaries depict a future full of clean energy and cleaner air. It's as if our need for clean air makes us willing to ignore the development and natural resource costs associated with powering all of these high-energy devices we keep adding to our lives. I'm beginning to believe most of us have certain fears which keep us from crossing a line where everything crashes into a horrific vision where every breath has a painful consequence.
