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.

Daniel Moran, PhD, associate professor of biomedical engineering and neurobiology in the School of Engineering & Applied Science at Washington University in St. Louis, is developing brain-computer interfaces based on grids of electrodes that lie beneath the skull but outside the dura mater, the protective membrane that covers the brain. His next project is to slip a thin 32-electrode grid he designed with a colleague under a macaque’s skill and to train the monkey to control — strictly by thinking about it — a computational model of a macaque arm.

Eden Brukman (left), vice president of the International Living Building Institute, presents Chancellor Mark S. Wrighton with an award recognizing Washington University in St. Louis’ Living Learning Center as a Living Building. The Living Learning Center, located at the Tyson Research Center in west St. Louis County, was one of only two buildings to meet the institute’s Living Building Challenge in 2010.

Washington University in St. Louis students are helping students in Scott McClintock’s middle school science class at Maplewood-Richmond Heights use wind turbines, solar collectors and other materials to investigate ways to maximize energy from renewable sources.
