With a one-year grant from Washington University’s International Center for Advanced Renewable Energy and Sustainability (I-CARES), researchers at Washington University in St. Louis plan to use some high-tech methods to better understand the processes, mechanics and interfaces that plants use to move iron from the soil, through water and into the plant.

Deeply concerned about an “innovation deficit” that is threatening the nation’s economic growth, Chancellor Mark S. Wrighton and Timothy M. Wolfe, president of the University of Missouri System, sent a joint letter last month to Missouri’s U.S. congressional delegation urging their support in helping close this innovation gap. Wrighton and Wolfe also  joined more than 160 university presidents and chancellors in signing an open letter July 31 to President Obama and the U.S. Congress asking them to restore federal investments in higher education and research.

Fuzhong Zhang, PhD, assistant professor of energy, environmental and chemical engineering, has received a Young Faculty Award from the Defense Advanced Research Project Agency of the U.S. Department of Defense. He is the first faculty member at Washington University in St. Louis to receive the award, which recognizes an elite group of scientists early in their careers at research universities.

Fuzhong Zhang, PhD, assistant professor of energy, environmental and chemical engineering at Washington University in St. Louis, works with Synechocystis 6803 — as well as other microbes and systems — in the areas of synthetic biology, protein engineering and metabolic engineering, with special focus on synthetic control systems to make the organism reach its untapped prowess. He says the biotech world has to overcome several challenges to put the engineered microbes in the applications stage.

Washington University in St. Louis is launching a new Climate Change Initiative aimed at expanding scientific research, education and public understanding of global climate change. A signature initiative of the International Center for Advanced Renewable Energy and Sustainability, the initiative will be led by Peter H. Raven, PhD, the George Engelmann Professor of Botany Emeritus and President Emeritus of the Missouri Botanical Garden.

​Created 60 years ago, the Assembly Series is Washington University’s premiere lecture series. Its chief mission is to present interesting and important voices, and it is designed to spark meaningful discussion and lead to greater understanding of our world today. Assembly Series programs are free and open to the public. The fall 2013 schedule, below, opens with First Year Reading Program author Eula Biss on September 9.​​​

Much of modern agriculture relies on biologically available nitrogenous compounds (called “fixed” nitrogen) made by an industrial process developed by German chemist Fritz Haber in 1909. Himadri Pakrasi, PhD, a scientist at Washington University in St. Louis, thinks it should be possible to design a better nitrogen-fixing system. His idea is to put the apparatus for fixing nitrogen in plant cells, the same cells that hold the apparatus for capturing the energy in sunlight. The National Science Foundation just awarded Pakrasi and his team $3.87 million to explore this idea further.

In the Aug. 6, 2013, online edition of Chemical Science, a team of scientists describes a testbed for light-harvesting antennas, the structures that capture the sun’s light in plants and bacteria. Prototype designs built on the testbed soak up more of the sun’s spectrum and are far easier to assemble than synthetic antennas made entirely from scratch. They offer the best of both worlds, combining human synthetic ingenuity with the repertoire of robust chemical machinery selected by evolution.

An interdisciplinary team of researchers and students from the School of Engineering and Applied Science, the Sam Fox School of Design & Visual Arts and Olin Business School at Washington University in St. Louis is working to create a more sustainable future for the university. Over the last year, teams have developed an experimental framework for testing environmentally friendly redevelopment strategies in a group of University-owned apartment buildings north of the Delmar Loop.

A recent report from the Global Entrepreneurship Monitor indicates that there are significantly fewer female entrepreneurs than male entrepreneurs around the world. This is not the case, however, at Washington University in St. Louis, where more than 40 percent of successful companies started by recent graduates through the university’s business entrepreneurship courses have been founded by women.
