For as long as I can remember, I've wanted to travel through space. There was only one problem...I get motion sickness from rolling over in bed. So, I opted to keep my feet on the ground. However, for those who can stomach zero gravity, NASA wants to keep such hardy ones healthy. So the agency awarded the University of Michigan Medical School's Center for Biologic Nanotechnology a $2 million grant to develop nanosensors—nano-scale devices that travel inside astronauts' white blood cells. These sensors will detect early signs of damage from radiation or infection. Created from synthetic polymers called dendrimers, the devices are fabricated layer-by-layer into spheres with a diameter of less than five nanometers. Because the sensors are so small, they easily pass through membranes into white blood cells called lymphocytes, where they can detect the first signs of biochemical changes from radiation. To identify cell damage, researchers also plan to develop a retinal-scanning device—a laser capable of detecting fluorescence from infected lymphocytes as they pass one-by-one through narrow capillaries in the back of the eye.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
