Chuck, sorry to disappoint you. It would have been a lot more dramatic, that's for sure. I'd guess that the reason a real piranha was not used in the experiment was most likely because of the danger and hassle involved with handling a real piranha. I wouldn't want to tangle with one of those, even if sedated.
In some ways, we look to nature because -- well, where else are you going to look. In recent years, however, I've seen there is a more deliberate look to nature for innovation. This is even true in the pharma industry. They're looking to nature for medicinal drugs. For one thing, drugs occurring in nature don't have to go through the same multi-year qualification process.
Current military body armor uses a kevlar layer and a ceramic plate to provide protection against high powered rifle bullets. The kevlar is a woven fabric built up in layers at angles. The ceramic plate is added to provide protection from rifle bullets. Seems like that part of the armor is already being used. The overlapping scale idea is interesting. This might hold promise for lighter, stronger armor.
Joel, it's actually both. The scales' flexibility is important for multiple reasons, according to the original study, which stated that the corrugated surface helps enable the flexibility of the outer layer of scales, which in turn leads to the difficulty of penetration by piranha teeth.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
