I’ve been a fan of Natalie Portman since she was 12 years old, performing in an extraordinary, compelling film, “The Professional (1994).” In addition to being an Academy Award winning best actress, she’s also a co-author on a Journal of Chemical Education article. Yes, even chemists can take on Hollywood.

When Natalie Portman was a High School student at Syosset High School in Long Island, then Natalie Hershlag, she co-authored this paper in The Journal of Chemical Education:

“A Simple Method To Demonstrate the Enzymatic Production of Hydrogen from Sugar”

Perhaps not as compelling as “Black Swan,” but it is a reminder that great minds reside in surprising places, and that science is, ultimately, a social enterprise.


There is current interest in and concern for the development of environmentally friendly bioprocesses whereby biomass and the biodegradable content of municipal wastes can be converted to useful forms of energy. For example, cellulose, a glucose polymer that is the principal component of biomass and paper waste, can be enzymatically degraded to glucose, which can subsequently be converted by fermentation or further enzymatic reaction to fuels such as ethanol or hydrogen. These products represent alternative energy sources to fossil fuels such as oil. Demonstration of the relevant reactions in high-school and undergraduate college laboratories would have value not only in illustrating environmentally friendly biotechnology for the utilization of renewable energy sources, such as cellulosic wastes, but could also be used to teach the principles of enzyme-catalyzed reactions. In the experimental protocol described here, it has been demonstrated that the common sugar glucose can be used to produce hydrogen using two enzymes, glucose dehydrogenase and hydrogenase. No sophisticated or expensive hydrogen detection equipment is required-only a redox dye, benzyl viologen, which turns purple when it is reduced. The color can be detected by a simple colorimeter. Furthermore, it is shown that the renewable resource cellulose, in its soluble derivative from carboxymethylcellulose, as well as aspen-wood waste, is also a source of hydrogen if the enzyme cellulase is included in the reaction mixture.

I am always reminding my research students that they should consider getting their research published in a peer-reviewed journal; perhaps this example will get their attention!

    It is nice to know that somebody like Natalie Portman actually has a published article. It is an example that can be used in high school classrooms to show students it is cool to be interested in science.
