In a study published recently in Nature Communications, scientists in UCI s Department of Civil & Environmental Engineering showed that over the past century, the likelihood of stronger and more long-lasting dry spells grew in the Americas, the Mediterranean, western and southern Africa and eastern Asia.

Rowan civil and environmental engineering head receives STEM civic leadership award

Dr. Kauser Jahan founded Engineers on Wheels and Rowan s Attracting Women into Engineering. For Dr. Kauser Jahan, professor and head of the Department of Civil & Environmental Engineering at the Henry M. Rowan College of Engineering, working in leadership and outreach “becomes part of who you are.” The New Jersey STEM Pathways Network honored Jahan with the 2021 NJ STEM Civic Leadership Award in March. In addition to founding Engineers on Wheels, which in 2013 received national recognition from the WEPAN Outstanding Women in Engineering Program Initiative, Jahan also founded Rowan’s Attracting Women into Engineering outreach program in 1999. For those of us who are passionate about the future of STEM education, our job is not only getting students excited about engineering careers, but also reaching out to underrepresented populations, Jahan said.

Genetically engineered grass cleanses soil of toxic pollutants left by military explosives, new research shows

UW researchers genetically engineered a switchgrass (foreground) to break down the explosive chemical RDX using genes from a soil bacterium. The researchers also grew a few thousand of the plantlets in the lab to prepare them to be transplanted in the field. From left to right: Ryan Routsong, Long Zhang, Stuart Strand. This photo was taken in 2018.Mark Stone/University of Washington Large swaths of U.S. military land are covered with munitions components, including the explosive chemical RDX. This molecule is toxic to people and can cause cancer. It also doesn’t naturally break down and can contaminate groundwater.
