NASA has created a chemical sensor accessory for the iPhone. Gizmodo calls this the day the first Tricorder was created, we call it cosmically cool in any time/space continuum.

The low-cost, low-power system can detect minimal concentrations of ammonia, chlorine gas, and methane, showing the values in an iPhone application. It can automatically communicate the results with other cellphones or the Enterprise's computer using Wi-Fi or 3G, and order massive teleportation evacuations if needed. OK, not true. No teleportation yet, but we are getting there.

Okay, now where's the transporter app?
