Science & Technology

A team of researchers at Washington University in St. Louis, headed by Srikanth Singamaneni, PhD, assistant professor of mechanical engineering & materials science, unexpectedly found the mechanism by which tiny single molecules spontaneously grow into centimeter-long microtubes by leaving a dish for a different experiment in the refrigerator.  This novel approach of making nano- and microstructures and devices is expected to have numerous applications in electronics, optics and biomedical applications.

Washington University engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air.  The device, known as the SXC ESP, was created by a team led by Pratim Biswas, PhD, the Lucy & Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the School of Engineering & Applied Science.

Engineers Week 2013 is packed with a variety of events celebrating engineers all week long. The week, founded by the National Engineers Week Foundation, is designed to increase the visibility of the School of Engineering & Applied Science at the university, collaborate between various engineering groups and promote the interaction among students, alumni, faculty, staff and engineering professionals.

Washington University in St. Louis administrators are urging Congress and the White House to reach a compromise to avoid wide-ranging, across-the-board federal spending cuts that would take effect March 1.

An undergraduate student at WUSTL helped create and launch a mobile app that helps students track the campus circulator shuttle. It’s called the “WUSTL Circulator,” and on its first day, it had up to four times as many downloads as typical new university apps.

Scientific efforts to explain feeblemindedness, delinquency and racial inferiorities date to the Spanish Inquisition. And while the horrors of Nazi Germany exposed fatal flaws in science’s quest to build the master race, the ethical dilemmas posed by the science of eugenics are far from behind us, warns an anthropologist from Washington University in St. Louis.

This winter (the Southern Hemisphere summer), postdoctoral research associate Aubreya Adams, PhD, spent a few months at the South Pole Station maintaining seismic equipment. This photoessay, based on her Facebook page, provides a glimpse of what it is like at the South Pole and what seismologists get up to when they go into the field to maintain seismic stations.

Every Tuesday afternoon, an undergraduate from WUSTL’s  School of Engineering & Applied Science heads back to middle school. Nick Okafor leads the after-school Young Engineers Club at Brittany Woods Middle School in University City. N’Desha Scott, a sophomore majoring in biomedical engineering, started the club last fall as a way to reach out to middle school students from groups traditionally underrepresented in the science, technology, engineering and math (STEM) fields.

Washington University in St. Louis’ Institute for School Partnership (ISP) and its signature science education program, MySci, take a major step forward Monday, Feb. 18, when they open the MySci Resource Center at 6601 Vernon Ave. Refurbished with the help of a $2.2 million grant from the Monsanto Fund, the MySci Resource Center becomes the nerve center of the ISP, WUSTL’s signature effort to strategically improve teaching and learning within the K-12 education community in the St. Louis region. ​

This fall Joan Strassmann, PhD, professor of biology in Arts & Sciences taught a course in behavior ecology that was also an official Wikipedia course that required students both to edit an existing Wikipedia entry and then either add 25 references and 2500 words to a second entries or to create new ones. “No work by students as good as Washington University’s students should ever end up in a professor’s drawer,” said Strassmann. “It was their responsibility as smart people who were getting a great education to help others.”
