In the near future, you may monitor your health and diagnose illness – all by swallowing a biosensor. Prof. Ben Terry of the University of Nebraska, Lincoln, describes this technology, which may sound like science fiction to many.
Columbia University researchers recently generated beating cardiac tissue from induced pluripotent stem cells, human cells that are able to differentiate into nearly any cell type. Using physical conditioning, the researchers produced samples with the hallmarks of mature heart tissue with just four weeks of cell culture. The work paves a concrete pathway to functional heart-on-a-chip platforms.
Biomedical engineers at Texas A&M University developed a hydrogel made from nanoflakes of synthetic clay and sugar chains extracted from seaweed. The gel could act as an injectable bandage to stop internal bleeding on a battlefield, in a surgical suite, or at an accident site.
A medical device company has developed a portable visor system that uses volumetric impedance phase-shift spectroscopy (VIPS) technology to detect severe strokes within seconds.
