Island Engineers, Engineering Islands:
In many ways, anthropogenic islands, like South Florida’s Mound Key or Nan Madol in Micronesia, serve as model systems for how human populations can affect pristine environments. This ranges from land modification due to forest clearance for agricultural and other activities to the introduction of invasive species and the extirpation or extinction of ...Scott M.

Advances in Surgery, 2014
Ultimately much work remains to be done in the companion fields of biomaterials and stem cells. Nonetheless, the monumental progress in TE that has been reported in the studies summarized here demonstrates that regenerative approaches to problems in general surgery need to be explored in more depth.

A quantum-dot heat engine operating close to the thermodynamic efficiency limits
Nature Nanotechnology, 2017Cyclical heat engines are a paradigm of classical thermodynamics, but are impractical for miniaturization because they rely on moving parts. A more recent concept is particle-exchange (PE) heat engines, which uses energy filtering to control a thermally ...

Engineered Microfibers for Tissue Engineering
ACS Applied Bio MaterialsHydrogel microfibers are hydrogel materials engineered into fiber structures. Techniques such as wet spinning, microfluidic spinning, and 3D bioprinting are often used to prepare microfibers due to their ability to precisely control the size, morphology, and structure of the microfibers. Microfibers with different structural morphologies have different

You never forget the first time humanity sent a man to space. Yuri Gagarin’s first trip beyond our planet’s atmosphere fuelled our imaginations, perhaps because we each had a different image in our heads of what Gagarin’s trip looked like.
