An experimental device made from layered filter paper is helping Rice University bioengineers study calcifying heart diseases.
The filter paper is structured in a way that mimics the layering of aortic heart valves, recreating the means by which cells spread through cardiac tissue in a laboratory setting. It may not look much like a heart valve, but in practice it simulates the proliferation process in the same way.
The photovoltaic power industry is well established in many regions and despite the sometime negative perception the end user demand in 2011 was strong and the total market for new installations passed the 26 GW mark
