Cockroaches Could Help Save Trapped Disaster Victims

CC.jpg
A system enabling cockroaches to locate trapped disaster victims is in development by researchers from North Carolina State University. Based on the findings of Dr. Alper Bozkurt and his team, each “biobot” consists of a Madagascar hissing cockroach that carries a “backpack” equipped with a microchip, wireless receiver/transmitter, and microcontroller wired to the insect’s antennae and cerci.


The cerci are sensory organs in the insect’s abdomen able to detect air movement and warn of potential predators, but when stimulated by the microcontroller instead they signal that something is approaching from behind and cause the cockroach to scuttle forward. Stimulating either of the antennae allows movement to be manipulated as well. When one of the cockroach’s antennae brushes against an unyielding object, it knows it can’t move that way and will change course, but a small electric charge can achieve the same reaction and steer the insect in the desired direction. Human operators as well as a Kinect-equipped computer have previously used the system to guide the biobots by wireless remote control, though an array of three-directional microphones was added to each cockroach’s backpack in the most recent study.

Software was able to determine the location of sounds based on an analysis of those each mic picked up and steer each biobot accordingly. Researchers hope that equipping biobots with a single high-resolution mic could eventually help them distinguish victims’ voices from other noises at disaster sites. Cockroaches wearing these mics could then be activated to seek out the source of detected voices, allowing rescuers to track them through transmitters and establish victims’ whereabouts.

Isn't history more fun when you know something about it?

Giving the Finger

Before the Battle of Agincourt in 1415, the French, anticipating victory over the English, proposed to cut off the middle finger of all captured English soldiers. Without the middle finger it would be impossible to draw the renowned English longbow and therefore they would be incapable of fighting in the future.

This famous weapon was made of the native English Yew tree, and the act of drawing the longbow was known as "plucking the yew" (or "pluck yew").

Much to the bewilderment of the French, the English won a major upset and began mocking the French by waving their middle fingers at the defeated French, saying, "See, we can still pluck yew!"

"PLUCK YEW!"

Since 'pluck yew' is rather difficult to say, the difficult consonant cluster at the beginning has gradually changed to a labiodental fricative 'F', and thus the words often used in conjunction with the one-finger-salute!

It is also because of the pheasant feathers on the arrows used with the longbow that the symbolic gesture is known as "giving the bird."

And yew thought yew knew everything!
 
Fantastic @Johan.thanks for sharing.interesting to see how technology has evolved
 
that would be a reciepe for disaster , i have a tendancy to lean left when slightly intoxicated !!!!!
 
Lucky basterd.he probably didn't no what to do with them all
 
Don't tell me you knew this:

Living inside the tiny hole outside your stomach (aka belly button) is an ecosystem the size of a rain forest. From exploring 60 belly buttons, researchers found 2,368 bacterial species, 1,458 of which may be new to science.

Interesting @Johan.i have never thought of it in that way
