Ingrid Fritsch, a professor of chemistry and biochemistry at the University of Arkansas, developed a new method—called magnetohydrodynamics—of using magnetic force to move fluids down small channels the width of a human hair. It is unlike current methods using electrokinetic pumping, centrifugal force, and mechanical pumping with microfluidic devices. Fritsch found that when the electromagnetic field is reversed in magnetohydrodynamics, the fluid flow reverses without need of mechanical manipulation. The finding may help researchers develop so called "lab on a chip" medical devices.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
