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.
Thirty years ago today, Tim Berners-Lee, then a research fellow at physics laboratory CERN, issued a proposal, titled "Information Management: A Proposal". This would go on to be the basis of the World Wide Web
