The blueprint for the human body is encoded in genes. Gene expression is the process by which those blueprints are converted into proteins that make up the body’s structures and send its signals.

When molecular biologists began analyzing the complete set of human genes (the human genome) in 2001, one surprise was that humans have as few as 30,000 genes when, given their complexity, they should have more than 100,000. How can humans have one-fifth as much genetic material as wheat, for instance, or share one quarter of their genes with fish?

One answer is that humans do more with fewer genes. While genes consist of chains of deoxyribonucleic acids (DNA), they are put into practice by chains of ribonucleic acid chains (RNA), which are modified copies of DNA. Messenger RNA (mRNA) is transported to cellular factories called ribosomes that receive instructions for building proteins by “reading” mRNA templates, a process called translation.

A lot of discussion on emissions revolves around mitigation rather than optimization but researchers at TU Delft have shown that creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%.

Earlier promising predictions, based on mathematical models and wind tunnel tests have been confirmed during road tests with an adapted trailer. This means that public-private platform PART (Platform for Aerodynamic Road Transport), has produced an application which can immediately be put into production.

It is expected that the cost of fitting aerodynamically-shaped sideskirts will be recouped within two years. Furthermore, the sideskirts can be fitted to approximately half the trucks currently in use in the Netherlands as the skirts can also be retrofitted.

Cracks in buildings that close without external help may seem a little far fetched but we already have a good template in the human body's ability to heal wounds by sending blood platelets to the affected area. In most cases the healing occurs without any need for external coagulants.

The body's natural response to damage was the starting point for the development of self-repairing polymer materials with the ability to recover with minimal external help.
