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 Feb. 17, 1864 -- and then sinking themselves. What happened?

840-hp 2018 Dodge Challenger SRT Demon comes wheelie-ready
As a kid playing with Hot Wheels, you probably dreamed of being a grown-up and pulling a wheelie when the light turned green. But you found out as you got older that they really don't make production cars like that. Well, that was then. The 840-hp Dodge Challenger SRT Demon, the world’s most powerful factory-production V-8, has arrived -- and it comes complete with wheelie-inducing Drag Mode Launch Assist.

Next Big Thing:
Father-son team create liquid metal 3D-printing system

A father-and-son team in the START-UP NY program in Buffalo, NY, have invented a liquid metal printing machine that could represent a significant transformation in manufacturing. A breakthrough idea five years ago by former University at Buffalo student Zack Vader, then 19, has created a machine that prints 3D objects using melted aluminum. The nozzle design, which uses a pulsed magnetic field, is key. Printing objects in steel is in the works.

Top Product: NanoSteel launches 3D-printable tool steel
NanoSteel, a leader in nanostructured steel materials, has launched its first product for the laser powder bed fusion additive manufacturing process. BLDRmetal L-40 is a case-hardening steel powder that provides high hardness and ductility (case hardness >70HRC, 10%+ core elongation) and prints easily on standard commercial equipment. This alloy provides superior performance to M300 maraging steel and is an alternative to difficult-to-print tool steels such as H13. Expanding the potential use of 3D printing in a wide variety of hard materials markets, BLDRmetal L-40 is designed to be used for parts including tools, dies, bearings, and gears.

Top Product: Thermoelectric alternative for beverage cooling
Laird's standard and custom thermoelectric cooling systems offer superior heat pumping capability with lower power consumption, noise, weight, and footprint compared to compressor-based systems. The 12-V or 24-V DC thermoelectric modules (TEMs) and thermoelectric assemblies (TEAs) offer reliability, design flexibility via vertical integration capabilities, and an overall lower cost of ownership. Thermoelectric coolers also operate at lower noise levels and provide a more environmentally friendly solution. This technology does not use ozone-depleting refrigerants, which must be phased out of new and existing equipment in the European Union by 2022.

Top Product: Infrared LED optimizes license plate recognition and more
Osram Opto Semiconductors is expanding its family of high-power infrared Oslon LEDs for illumination solutions to include a new wavelength -- 810 nm. The new SFH 4703AS infrared emitter will improve the performance of inspection and scanning camera systems, such as those used to read license plates. The additional wavelength enhances image contrast, making it easier to read patterns from recorded images at any time of day. At 1 amp current, the emitter generates 1 W of optical power. With this device, designers can now choose from mutually compatible emitters in three different wavelengths.

Top Product: Control 3D printing at the voxel level
Stratasys has introduced GrabCAD Voxel Print, a new software solution for its J750 3D-printing solution that provides true voxel-level control during the design and 3D-printing process. Manipulating microscopic voxels, which represent volumetric pixels and are the building blocks of 3D printing, enables users to achieve 3D-printed effects and properties not possible before. Combine this with the full-color, multi-material 3D-printing capability of the Stratasys J750 3D Printing Solution, and you open up a whole new world of digital materials and advanced structures.

The Rube Goldberg machine: A little history
Rube Goldberg drew thousands of cartoons of his crazy contraptions, but no one actually built one until Purdue University engineering students started a contest in the 1950s. Fast forward to the 21st century, and the official Rube Goldberg Machine Contest is now a global enterprise, with teams of all ages and stripes.

Next Big Thing in Army aviation? Lockheed Martin S-97 RAIDER is fast and furious
The Lockheed Martin/Sikorsky S-97 RAIDER is a next-gen light tactical prototype helicopter that can reach speeds of more than 220 knots, nearly double the speed of a conventional helicopter, and is capable of flying at 10,000 ft in 95°F heat. It can carry six troops and external weapons, and it aims to redefine helicopter flight during the 21st century. Based on Sikorsky’s Collier Award-winning X2 Technology, RAIDER incorporates the latest advances in fly-by-wire, flight controls, vehicle management systems, and systems integration. It also has retractable landing gear, active vibration control, a composite fuselage, active elevator and rudders, split torque transmission, and a rigid co-axial rotor system. These technologies enable the aircraft to operate at high speeds while maintaining the low-speed handling and maneuverability of conventional, single main-rotor helicopters.

On fire! See a steel ball bearing crushed by a hydraulic press
Some enterprising guys in Finland with a penchant for smashing stuff have created their own YouTube channel -- and they want to share all the fun. “Wanna see stuff getting crushed by a hydraulic press?” they ask. This time around, they crush a steel ball bearing, and as a bonus they catch the action on a borrowed super high-speed camera shooting 320,000 frames per sec. Watch what happens when the steel explodes, sending tiny particles outward at Mach 2.44 (18,000 mph).

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!

Robots revive 74-yr-old Alabama metal hanger manufacturer
Globalization has its advantages, like cheap socks and affordable smartphones. But for some manufacturers, the global economy has taken a toll. In recent decades, increased competition from low labor-cost countries has made it difficult for many companies to manufacture their products in their home countries. With help from both Fitz-Thors Engineering and KUKA Robotics, U.S. manufacturer M&B Hangers thrives despite fierce global competition -- and holds strong to its position as the last-standing producer of its product category in the United States.
