I have seen the future, and it is cilia. Yes, you read that right: those trillions of tiny hair-like extensions that carpet every inch of your body could bring scientists’ visions of a universal class of “smart” materials that change and adapt when subjected to various stimuli closer to reality. These artificial cilia could one day do everything from testing drugs and monitoring air quality to measuring glucose levels and detecting electromagnetic fields.
While largely ignored over the past century (or, at best, dismissed as being purely vestigial), scientists are finally beginning to appreciate the many vital functions they perform in and outside of our bodies. Much like an antenna or sensor, cilia gather information from their surroundings and react—by activating a cellular process or shutting down cell growth, for example—if something seems amiss. They can also act as miniature roads or railways, carrying dirt, bacteria and other noxious materials out of our lungs or shuttling a fertilized egg from the ovary to the uterus. And, perhaps most importantly, cilia make it possible for us to see, hear, smell, and otherwise feel the outside world.
Now some researchers believe that cilia-like structures could bring their sensory prowess to medicine, environmental monitoring and a number of other fields. Leading the charge is Marek Urban of the University of Southern Mississippi who has created a copolymer film with hair-like filaments that mimics the functions of normal cilia. (more…)
If your primary method of thwarting criminals is a hyper-intelligent car, that car really needs to be bullet proof or else your career will be short. But if your hyper-intelligent car is also super fast and high-performance, you don’t want to install heavy armor panels that destroys that performance. The current version of
