It’s the burgeoning field of “BioMimicry” – the imitation of natural processes in a man made device. Mayfly gills and their movement appear to be the last great hope for canaries.

A tiny robotic replica of a mayflies gill is likely to replace the old “canary in a coal mine” – as its physical properties and size means it can move both airborne and waterborne particles over a sensor head without inducing a counter current with its movement.

The next step will be to construct a tiny artificial micro-robot that can reproduce the switchable gill action of the mayfly nymph. Such a mechanism could be installed in sensors intended to detect unhealthy air in otherwise stagnant areas, such as in subway stations or mines. If a miniature set of robotic mayfly gill plates can move air over a sensor, potentially harmful substances can be detected faster – and no canaries would be harmed in the process.

It’s a big deal because all manner of unhealthy items live in stagnant dank areas, and the speed the sensor registers means someone has a running start for the exit.

This may cause some consternation for us ardent fishing types, some fellow waving and yelling about BWO’s might be complaining about your Bad Wader Odor.

Oh, Hell – just throw a rock at Mr. CandyAss..
