A new case study shows that biomimicry, a relatively new field that seeks to emulate nature to find solutions to human problems, can potentially expand intellectual property, increase energy savings and accelerate product innovation.
New research is giving a whole new meaning to feeling your skin crawl. Skin cells typically spend their entire existence in one place on your body. But researchers have seen how the cells will alter the proteins holding them in place and move to repair a wound.
Our brain is home to different types of neurons, each with their own genetic signature that defines their function. These neurons are derived from progenitor cells, which are specialized stem cells that have the ability to divide to give rise to neurons. Neuroscientists have shed light on the mechanisms that allow progenitors to generate neurons.
Using a sophisticated, custom-designed 3D printer, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients. Scientists said they printed ear, bone and muscle structures. When implanted in animals, the structures matured into functional tissue and developed a system of blood vessels.
As we continue to shrink electronic components, top-down manufacturing methods begin to approach a physical limit at the nanoscale. Rather than continue to chip away at this limit, one solution of interest involves using the bottom-up self-assembly of molecular building blocks to build nanoscale devices.
