BiomimicryBiomimicry From bios, meaning life, and mimesis,

meaning to imitate.

A new discipline that studies nature’s best ideas and then imitates these

designs and processes to solve human problems.

 

Termite-Inspired Air Conditioning Eastgate (Harare, Zimbabwe)

uses only 10 percent of the energy of a conventional building its size, saved 3.5 million in air saved 3.5 million in air conditioning costsconditioning costs in five years, and has rents that are 20% lower than a newer building next door.

Abalone Inspires Lightweight

Building Materials The shell of the Abalone is a remarkable ceramic that is

twice as tough as our high-tech ceramics. Mother-of-pearl is

composed of alternating layers of calcium carbonate and

protein. The combination of The combination of hard and elastic layers gives hard and elastic layers gives nacre remarkable toughness nacre remarkable toughness

and strengthand strength.

Nautilus inspired fan A three-dimensional spiral is

found in the shells of Nautilus. Flow through these

geometrically consistent forms with far less friction and more efficiency. PAX Scientific has

designed propellers, impellers, and aerators based on this

shape. Tests showed that this Tests showed that this

technology reduces energy technology reduces energy requirementsrequirements..

Yondelis® is a marine derived antitumoral agent Yondelis® is a marine derived antitumoral agent discovered in the colonial tunicatediscovered in the colonial tunicate Ecteinascidia turbinata and now produced synthetically. Yondelis binds to the minor groove of DNA interfering with cell division and genetic transcription processes.

Yondelis® is currently being developed by PharmaMar in partnership with J & J
