Whether watching the All-Star Game, a World Series game or just a regular-season Tuesday afternoon game, it’s nearly guaranteed that fans will see daring slides, both feet-first and head-first, and even slides on bang-bang plays at first. Who gets there faster, the head-first slider or the feet-first? The head-first player, says David A. Peters, Ph.D., the McDonnell Douglas Professor of Engineering at Washington University in St. Louis, and big-time baseball fan. He says it’s a matter of the player’s center of gravity.

A team of researchers headed by biologists at Washington University in St. Louis has sequenced the genome of a unique bacterium that manages two disparate operations — photosynthesis and nitrogen fixation — in one little cell during two distinct cycles daily.

Researchers at Washington University in St. Louis are proposing to borrow a process used in breweries and wastewater treatment facilities to make corn ethanol more energy efficient. They are exploring the use of oxygen-less vats of microorganisms that naturally feed on organic waste produced from the ethanol fermentation process.

Physics has a reputation for being the toughest of the high school science courses. But visual models of motion, acceleration, waves, projectiles and other principles help students of all ages build an understanding of physical science concepts. For Jack Wiegers, biology instructor, and Patrick Gibbons, Ph.D., professor of physics, these ideas are a key part of science for students from kindergarten through grade 12. The pair instructs four Science Outreach graduate courses in physical science designed for K-8 teachers. They’ve also worked with high school teachers in short workshops and in year-long professional learning communities.

What should the Midwest do before and after a major earthquake?The earthquake that hit the lower Midwest on April 18 of this year was a hearty 5.2 on the Richter scale and got the attention of the St. Louis region. What if a larger quake — occurring either in the New Madrid Fault or Wabash Valley Fault — were to hit the region? How would we respond? To address these concerns, the Department of Mechanical, Aerospace and Structural Engineering at Washington University in St. Louis is presenting a series of seminars and workshops on the topic of reducing the damage that could occur if a strong earthquake strikes the area again.
