 | New Revolutionary Revolox™ Self-Locking Ring for High RPM
The revolutionary Revolox Self-Locking Retaining Ring from Smalley. Secure and easy locking for your high-speed rotational needs. The "dimple and slot" design prevents ring expansion, safely securing your application at high RPM. This makes it possible to operate at higher speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading. The Revolox self-locking ring enables engineers to cost-effectively design for high RPM requirements and with ease of assembly for high-volume applications.

 | 50 years ago: Apollo 15 first lunar rover drive and the Genesis Rock
The fourth Moon landing mission began on July 26, 1971, with the launch of Apollo 15. Astronauts David R. Scott and James B. Irwin went to the surface, while Alfred M. Worden remained in orbit aboard the Command Module Endeavour. Scott and Irwin conducted four spacewalks, including three excursions using the Lunar Roving Vehicle for the first time, deployed experiments, and collected 170 pounds of rock and soil samples to return to scientists on Earth.

 | Secret of Stradivarius violin sound solved? Surprising finding
The violins crafted by Antonio Stradivari in the late 1600s and early 1700s produce a sound so pure that some are valued at $10 million or more. But what's the secret sauce behind the instruments' acoustical superiority? A Texas A&M University scientist has been working on an explanation for years -- and we bet you can't guess it before you read on.

 | Diamond vs. a hydraulic press -- which will win?
The fun folks over at the Hydraulic Press Channel are at it again. This time, they take a look at crushing raw diamonds. Will the steel press win out, or will the diamond hold its own? Some great slo-mo, close-up photography helps with the judging -- especially with the man-made diamond material, which is the second sample tested. It's a pretty interesting match-up.

| | Videos+: Technologies and inspiration in action | How a Formula 1 team uses Volume Graphics for non-destructive part testing
Because Formula 1 racecars are among the fastest vehicles on earth, ensuring that every part of these speed machines is perfect is critical for safety as well as performance. Watch how the Alpine F1 Team's non-destructive test (NDT) laboratory in Enstone, England, uses Volume Graphics to validate car parts quickly and accurately. In some cases, it takes just 20 minutes instead of the usual full day needed to inspect the parts with conventional ultrasound. Neat stuff.
