The natural world provides many sources of inspiration for engineering novel systems beyond those used to restore or augment human function. Three general approaches through which engineering can achieve impact via leveraging knowledge and understanding of natural biological systems are of particular interest and are outlined below.
Bio-inspired/Bio-informed
Inspiration from biology is used to engineer components and systems. Naturally occurring chemistry from both animals and plants has driven advances in materials science. Design of engineered systems has been informed by nature-based mechanical solutions. Neuroscience is under scrutiny to provide inspiration for brain-based data storage and computational capabilities. In the future, we stand to learn much from biological mechanisms of resilience and adaptation to inform the design of engineering structures and systems.
Repurposing Biology
Biological constructs may be adopted and adapted for purposes beyond their existing biological function. A classic example of this is the use of DNA molecules for data storage, building on the remarkable integrity and potential for error-free replication of this macromolecule. Additionally, intense interest is focused on designer organisms—products of synthetic biology—that may afford functionalities from mining, to agriculture, to bio-foundries. Engineered living systems may provide building blocks for next-generation sustainable engineering.
Improving on Biology
It’s also possible to envisage engineering components and systems that go “beyond biology." One potential example is manipulating the interactions between species in different kingdoms. This “interkingdom engineering” has breathtaking potential to improve human health, for example by manipulating the human microbiome to ameliorate obesity or interrupting interspecies virus transfer to diminish disease spread.
Participants will engage in breakout discussions with interdisciplinary peers to collectively identify what fundamental research is needed to make these scenarios seem not so impossible. The following challenges are posed by our Thematic Task Force as a lens through which to posit visioning bold possibilities at the interface of biology and engineering.
