A major achievement for design engineers is building precise control mechanisms for active processes. Lives depend on the precision in which certain processes are maintained, such as the manufacture of drugs.

Mankind’s attempts at bioengineering have yet to match the precision of some techniques already found in nature: cloning, tissue culturing, and gene therapy. Recent studies have explored how these processes operate in amoebas, aphids, and parasitic wasps, respectively.

Certain aphids manipulate plant tissues to form a hollow gall in which they then reside. But aphids will also help heal plant tissue that they’ve damaged. This behavior serves as a vital self-defense mechanism, because when the gall’s walls are eaten by caterpillars, the tender aphids inside become easy prey for other insect predators.

Stem cell treatments have proven successful for many diseases, and there is great promise that new treatments will emerge to combat even more maladies. These successful treatments involve inserting correctly functioning stem cells into tissues where native mutated cells have caused disease.

Plants use biological systems that harvest light energy from the sun to convert environmental water and carbon dioxide into tiny carbon/hydrogen energy units stored within them.
