The word "fail" usually implies that something went wrong. To fail a school exam decreases the chances of passing the course, and failing a physical exam portends poor health. But when scientists studied yeast and bacteria that "fail to optimize" the production of certain proteins, they discovered that's actually a very good thing.

Some rocket cars can accelerate at 5 g-forces.¹ For comparison, respectable acceleration for a sports car amounts to half a "g," and people faint when accelerating at 5g's. But long before the rocket car was invented, fish were accelerating just as forcefully into the mouths of giant salamanders. How did these thin-skinned amphibians acquire rocket-force mouthparts?

Most people have heard of "stereo sound," but not many may be familiar with "stereo vision," which helps many mammals discern depth. Seeing and hearing in stereo helps creatures living above ground, but moles need different equipment. Biologist Kenneth Catania of Vanderbilt University conducted three clever experiments to see if the blind eastern American mole used "stereo smell."

New surprises revealing complex bio-engineering keep emerging as evolutionary scientists continue to unwittingly obey the biblical command to "observe the ant"(Proverbs 6:6; 30:25). The latest bio-engineering discovery is that a key component of ant colony survival is based on sound (acoustic) communication systems.¹
