Defying textbook science, study finds new role for proteins

January 2, 2015 7:44 am | by Julie Kiefer, Univ. of Utah Heath Sciences Office of Public Affairs | News | Comments

Open any introductory biology textbook and one of the first things you’ll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body’s cells. Results from a study published in Science defy textbook science, showing for the first time that the building blocks of a protein, called amino acids, can be assembled without blueprints.

New technology makes 3-D tissues, maybe organs in the future

December 22, 2014 10:34 am | Videos | Comments

A new instrument could someday build replacement human organs the way electronics are assembled today: with precise picking and placing of parts. In this case, the parts are not resistors and capacitors, but 3-D microtissues containing thousands to millions of living cells that need a constant stream of fluid to bring them nutrients and to remove waste. The new device is called “BioP3” for pick, place, and perfuse.
