The work is fun but is also “real” science, and the publication on properties of bone-like materials made by the Lego robot is found here.

The Google Science Fair is targeted at students around the world from 13-18 years old, and more information can be found here.

Michelle’s book is out and available for purchase:

Written by expert practitioners in the field, this guide explores nanoindentation focusing on biological applications. The first section presents basics of nanoindentation, including the background of contact mechanics underlying indentation technique and the instrumentation used to gather mechanical data. Covering the applications of this technique, the second section discusses various topics, such as mineralized and non-mineralized tissues, cells and membranes, and cutting-edge applications at the molecular level. Well-researched and indispensable, this volume highlights the current challenges in the field while providing insights into the future.

The article appears in a special issue of CMES focussing on contact mechanics, and edited by Prof. Selvadurai of McGill University. The paper describes an algorithm for fast analysis of indentation curves, with output parameters including the hydraulic permeability. This work eliminates the need to run reverse-FE models of individual indentation creep load-time plots, and allows for permeability mapping in short time-frames along with modulus mapping. Further, a universal database serves materials with a wide range of material properties, and the utility of the method is demonstrated for materials with kPa (hydrogel) to GPa (bone) elastic modulus values.

The group, which formed in the department’s 4D13 Architectural Engineering module, was a mix of architects and engineers. The winning design was for an eco-friendly house powered in part by living algae contained in bioreactors integrated into the house design. This is the second award for this group and this project, previously they were finalists in the Cambridge University Entrepreneurs’ business concept challenge. Congrats to Oliver and his colleagues!

The study examined, using a wide variety of characterization techniques, the bone-like material formed by embryonic stem cells, adult stem cells and differentiated osteoblast cells. Interestingly, the material created by the embryonic stem cells was least “bone-like” while the tissue produced by the adult cells was both bone-like and similar to the osteoblast-derived tissue. Mechanically, there was about an order of magnitude difference between the tissue types, with embryonic cell-derived tissue demonstrating significantly smaller stiffness values compared with the other two groups. A write-up of the study appears in Nature Reports Stem Cells and the paper appeared recently in Nature Materials.
