Science & Technology

Students, faculty and staff hosted aspiring scientists March 26, April 2 and April 9 during “Catalysts for Change” workshops aimed at introducing female high school students to science, technology and engineering fields. Workshop students launch containers — designed using straws, cotton balls, rubber bands and tape — outside of the Lab Sciences Building. They competed to see who could launch their container the farthest without breaking an egg protected inside.

Yan Yi “Anny” Chung is the winner of the 2011 Stalker Award. The award is given to the graduating senior in biology whose undergraduate career was marked by outstanding scientific scholarship as well as contributions to the university in areas of artistic expression and/or community service.

The National Research Council is conducting a series of “Town Hall” meetings across the country to roll out the Planetary Science Decadal Survey 2013-2022 Wednesday, April 6, and the McDonnell Center for Space Sciences at Washington University in St. Louis will be hosting one of the events at 7 p.m. Wednesday, April 6, in Room 201, Crow Hall. It will consist of a one-hour presentation by Amy Simon-Hall of NASA’s Goddard Space Flight Center, who was a member of the survey’s steering committee, followed by a one-hour question-and-answer period.  

The premise behind Tom Bernatowicz’s innovative introductory physics course is that students should understand — even if they sometimes can’t fully share — the enthusiasm physicists feel their work. “We love physics, and we want our students to love it, too,” says Bernatowicz, PhD. “We’re not saying we’ll make it easy just so that they’ll love it, but we do want them to understand because it’s something we ourselves cherish and we want them to see how great it is.”

Tom Bernatowicz, PhD, professor of physics in Arts & Sciences, began at WUSTL studying stardust, tiny crystals of material that formed around dying red giant stars or in exploding supernovae. While he remains interested in these tiny grains, lately he has been devoting much of his time to creating an introductory physics course that is so lively and engaging the students leave understanding why physicists are so passionate about their work.

In Counting from Zero a computer security expert named Mick O’Malley must track down and thwart an enormous botnet, or network of zombie computers organized to receive commands over the Internet and perform the hacker’s bidding. The novel, by Alan B. Johnston, who teaches engineering courses at Washington University in St. Louis, is both a fast read and a chilling tutorial on the the increasingly serious threats to computer security.

Edward W. Kolb, PhD, a cosmologist at Fermi National Accelerator Laboratory and a professor at the University of Chicago, will deliver two talks April 15 and 16 as part of the McDonnell Distinguished Lecture Series, sponsored by Washington University in St. Louis’ McDonnell Center for the Space Sciences.

A team of researchers, including earth and planetary scientists from Washington University in St. Louis, for the first time has been able to reconstruct both ocean temperature and general ice thickness of massive glaciers during one of the biggest mass extinctions in history hundreds of millions of years ago. The extinction, which occurred between 445 and 443 million years ago in the Late Ordovician Period, is one of the five biggest mass extinctions in Earth history, wiping out an estimated 75 percent of simple marine species.

Practice may not always make perfect, but a novel study of Midwestern middle school science students suggests it just might. New research from Washington University in St. Louis shows that students who received three quizzes on content questions before a unit test performed at the “A” level on those test questions, compared with a “C” level on questions that were not quizzed beforehand but still on the test.

A research group at Washington University in St. Louis has received more than $2 million to test a biomimetic material that promises to improve the success rate of the more than 75,000 rotator cuff (shoulder tendon) repairs performed each year in the United States. The natural attachment of tendon to bone relies on a transition zone where the material properties of bone shade into those of tendon. The biodegradable patch would provide an environment where stem cells could recreate this transition after surgery, making repairs less prone to failure.
