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.

For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

Early in my career, I worked as a draftsman and remember the days of drawing on vellum with numbered pencils and Mylar with plastic lead. This was a fun experience in the sense that I ...
I've been using workstations for more than 10 years and love finding ways to get more performance from my system. With demanding professional applications that require more power each ...
A lasting memory from my first job as an engineer in an auto assembly plant is standing on hard concrete at six in the morning, vending-machine coffee clutched in hand, listening to ...
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
