Veteran New Yorker journalist Elizabeth Kolbert visits the WUSTL campus at 4 p.m. Wednesday, Sept. 17, in Graham Chapel in the next installment of the Assembly Series. Her book, “Field Notes From a Catastrophe: Man, Nature, and Climate Change” (2006) has been applauded as an unbiased overview of an urgent environmental crisis. Growing out of […]

Veteran New Yorker journalist Elizabeth Kolbert will explore the debate over global warming based on her groundbreaking book “Field Notes from a Catastrophe: Man, Nature, and Climate Change” for the Assembly Series on Wed., Sept. 17 at 4 p.m. in Graham Chapel.

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.

Crowley will use the WUSTL programmable network platform that can scale real-time information sharing over several orders of magnitude, from a handful of interconnected platforms to thousands and tens of thousands. He hopes to facilitate better information sharing in the military.

This could shed light on the behavior of neutron stars, above.Scientists have studied superconductors and superfluids for decades. Now, researchers at Washington University in St. Louis have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to describing previously unknown superconductor behavior, these calculations could change scientists’ understanding of the motion of neutron stars.

WUSTL computer scientists who work on robots say the machines still need the human touch.War casualties are typically kept behind tightly closed doors, but one company keeps the mangled pieces of its first casualty on display. This is no ordinary soldier, though — it is Packbot from iRobot Corporation. Robots in the military are no longer the stuff of science fiction, and WUSTL’s Doug Few and Bill Smart are on the cutting edge of this new wave of technology. Few and Smart report that the military goal is to have approximately 30% of the Army comprised of robotic forces by approximately 2020.

Ultra-miniature bialy-shaped particles — called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City — could soon be carrying medicinal compounds through patients’ bloodstreams to tumors or atherosclerotic plaques. The nanobialys are an important addition to the stock of diagnostic and disease-fighting nanoparticles developed by researchers at the School of Medicine.
