a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronise the animal's legs when it launches into a jump.
The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the "first observation of mechanical gearing in a biological structure"......
Bacteria swim through fluids by using a number of rotary motors embedded in their cell walls to drive thin helically shaped filaments in a clockwise or anticlockwise direction. Researchers have used this motion to propel micro-structures but, as the bacteria movement is random, it is difficult to control without the addition of chemicals.
Now, Roberto Di Leonardo and colleagues at the University of Rome "La Sapienza" have shown how to exploit the motion of E. coli without controlling the bacteria in any way. They exploit the fact that a collection of bacteria immersed in a liquid represents a non-equilibrium thermodynamic system by virtue of the self-propulsion of the bacteria. This non-equilibrium system, they say, should confer ordered motion on an asymmetrically shaped object, in contrast to the random, Brownian motion, that thermal gas molecules would generate.
What we see in this discovery is another marvelous design by a Creator who reports in His Word that He created each kind of living thing within the first six days of earth’s existence about 6,000 years ago. He created living things able to reproduce variety, but only within their created kinds. Nothing we see in observable biology is inconsistent with our Creator’s claims in His Word.

I will show wonders in the heavens
and on the earth,
blood and fire and billows of smoke.
The sun will be turned to darkness
and the moon to blood
before the coming of the great and dreadful day of the Lord.
