Proper procedures for storage, mounting, lubrication and alignment can increase the lifespan of bearings, writes Paul Sadimas, an application engineer at SKF USA. Bearings should be stored flat and off the floor in a cool, clean, shock-free environment.
A bit of fun engineering designed to thwart thieves who steal delivered packages from porches has generated more than 54 million YouTube views for mechanical engineer Mark Rober. His fake package "glitter bomb" is one example of the neat things about being an engineer, he says, because "unlike most of the people in the population, you have a much better opportunity to build something physical that achieves a task."
In the 1950s, rocket scientist Wernher von Braun popularized the idea of a giant rotating space station to mimic the effects of gravity by generating centrifugal force. Decades later, a group of space enthusiasts at the Gateway Foundation are proposing the idea as a real possibility.
In July, the American Society of Mechanical Engineers will release an updated version of its Boiler and Pressure Vessel Code, including 42 minor and major changes across 12 sections, including power boilers, heating boilers, construction of power vessels, welding and brazing, and nuclear family components.
The aging of the workforce and long workweeks are evident in the latest Plant Engineering Salary Survey. As of last year, the report also reveals an average base salary in low six figures and a broadly positive attitude toward the introduction of robotics and the industrial internet of things.
Accelerate your professional development with ASME Learning & Development's nuclear learning program, May 20-24, 2019, in Pittsburgh. The courses are intended for engineering professionals who want to gain a more in-depth understanding of nuclear and power piping codes and standards and their applications.

Ubiquitous keyboards may one day be replaced by finger gesture technology, thanks to a new device that straps onto a user's knuckles. Learning to use the Bluetooth-connected TAP device takes some time, TAP Systems co-founder Dovid Schick says, but ultimately it's much more intuitive and ergonomic, using muscle memory to generate copy.
A 3D-printed implant embedded with neural progenitor cells shows promise for healing traumatic spinal injuries. Developed by University of California at San Diego researchers, the device specifically addresses the problem of orderly head-to-tail growth of axons at the injured site, which is crucial to restoring normal nervous system function.
Airbus is winding down production of its iconic A380. The economics for airlines no longer added up, with the giant four-engine plane requiring a nearly full passenger load on each flight to break even on costs.
Kidney organoids hold immense potential for regenerative medicine and drug testing but are limited by their lack of a pervasive blood vessel system, or vasculature. Harvard University bioengineers have developed a novel solution that introduces fluidic shear stress to stem cell-derived kidney organoids, allowing them to progress further previously possible.
