A researcher at McGill University in Montreal has refined an approach to developing auxetic material based on geometric patterns he observed in Iran. Auxeticity is a property which refers to multi-directional expansion, when stretched, rather than getting wider and thinner. The development is important because of the role it could play in the medical, construction, and aerospace fields, among others. One example is the use of auxetic material in fabricating advanced stents for cardiovascular care. Another relates to anti-ballistic composites. Venture capitalists may want to think twice about patrolling Silicon Valley for potential; research universities can be just as alluring. ■
