| | Feature articles | Mystery of Civil War sub crew deaths solved scientifically?
When the Confederate submarine HL Hunley was raised from the ocean floor in 2000, the skeletons of its eight crewmembers were found seated at their respective stations with no physical injuries or indications that they were attempting to escape after sinking the Union ship Housatonic on February 17, 1864 -- and then sinking themselves. What happened?

 | Gun barrel honing system hits target for Pac-Nor Barreling
Manufacturing precision rifle barrels has always been something of an art that involves hand lapping of the bore surface twice, before and after the rifling profile is cut or swaged in by a rifling button. But hand lapping is time consuming and labor intensive, and it may not always give the best result. Enter Sunnen's HTE honing machine.

 | New multi-turn sensors with a clutch
Novotechnik, U.S. introduces the ML Series of Multi-Turn Rotary Sensors. These sensors feature a unique friction clutch instead of the end-stops typically found on mechanical multi-turn sensors. The clutch produces a click sound to let users know they have reached end-of-range, and it permits continued turn past end-scale. Compare this feature to a device simply breaking as it is turned past its end-stops. Compact in size, ML Series sensors have a 1/2-in.-sq profile and include models with 6, 10, 25, 50, or 100 turns. Applications include forklifts, sliding gates, electric drive feedback, compactors, and medical devices.

 | 3D-printing materials program for large manufacturers
Carbon, a Silicon Valley-based 3D manufacturing company, has announced a materials program that will offer some of its 3D-printing polymer resins via bulk packaging, enabling a 40 percent price reduction for high-volume manufacturers. The first material to be offered will be RPU (rigid polyurethane) 70, which Carbon will initially sell for $150/liter, down from $250/liter. Working with its network of global supply-chain partners and integrating novel approaches for dispensing and distributing resins to a fleet of printers, Carbon expects to further reduce the price to less than $100/liter over the next year. Ford and adidas are among the first companies to take advantage of these new production offerings.

 | He's alive! How did Dr. Frankenstein do it?
Creating life is no easy task, even for Dr. Frankenstein. Before the lifeless amalgamation of human parts can be animated, they must be securely fastened together. Adequate torque must be applied to the Monster's neck bolts, lest it goes the way of the headless horseman. FUTEK's TRS series rotary torque sensor and LTH series donut load cell are combined to verify the applied torque and bolt loading is sufficient to securely fasten the Monster's head.

| | Videos+: Technologies and inspiration in action | 20th anniversary of supersonic car land speed record
On Oct. 15, 1997, the British Thrust SSC team set the World Land Speed Record of 763.035 mph -- making it the first and only car to reach speeds faster than the speed of sound. Driver Andy green, also a Royal Air Force fighter pilot, describes in detail what it was like to make the historic final run and keep this awesome twin-engine machine on the ground in Nevada and on a straight course. Currently, Green is prepping to set a new land speed record of 1,000+ mph in the BLOODHOUND SSC jet-engine car in South Africa in 2019. Fascinating!
