By creating molecular 'bridge,' scientists change function of a protein

... Chen and Huimin Zhao, a professor of chemical and biomolecular engineering, describe what they call a "simple and efficient method for creation of novel protein functions in an existing protein scaffold." In doing so, Zhao and Chen skirted the two time-and-labor-consuming approaches tried repeatedly in the past ...

Researchers devise way to mass-produce embryonic stem cells

... said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University. Federal rules forbid the federal funding of research on human embryonic stem cell lines that aren't listed on the National Institutes of Health's Human Embryonic Stem Cell Registry. There are currently 22 embryon...
