In a decisive move to accelerate warfighting capability and eliminate industrial bottlenecks, the U.S. Navy has released new technical requirements designed to rapidly scale the use of metallic 3D-printed materials across the submarine enterprise. The new standards strip away legacy administrative and engineering hurdles, clearing the launchpad for additive manufacturing (AM) to be integrated directly into submarine construction, maintenance, and combat-ready repair at unprecedented speeds.

Researchers from the Karlsruhe Institute of Technology (KIT) in Germany and the University of Tsukuba in Japan have developed a world-first, heat-driven elastocaloric cooling system that leverages waste heat and/or solar energy for sustainable cooling. The new cooling system combines two nickel-titanium foils: a heat-responsive foil generates motion, which a second foil uses to produce cooling.

[Credit: All images courtesy of Jaguar] Two years after its controversial concept unveiling (It's pink! It doesn't look like a Jaguar! Oh no, it's an EV!), Jaguar's all-electric Type 01 grand tourer (GT) has finally hit the real-world asphalt. The 2024 Jaguar 00 EV concept images shocked the automotive world -- and that was what the brand wanted. In the end, the designers stayed remarkably true to the sketches.

An Australian company recently announced a major milestone in real-world quantum sensing deployments. In a world-first field demonstration, Q-CTRL successfully navigated a maritime vessel without GPS using a new form of software-ruggedized quantum gravimeter. Through a series of trials in the Coral Sea off the East Coast of Australia, Q-CTRL performed autonomous gravity mapping and GPS-free quantum-gravimetric navigation, achieving the key metric of one-nautical-mile positioning accuracy.

Optical Gaging Products has introduced the SmartScope® E18, a compact, benchtop video measurement system. Featuring a 12" x 12" stage, IntelliCentric™-E fixed-lens optics, and VIRTUAL ZOOM™ technology, it offers fully automatic 3-axis performance without taking up floor space. Standard LED lighting, a rigid fixed-bridge design, optional touch probes, and advanced metrology software ensure accurate, repeatable inspection. Learn more.

By Christoph Elhardt, ETH Zurich The back wheel of the slightly aging bus stands on a plate about the size of a shopping trolley. Suddenly, the bus's battery begins to charge. Ten percent, 20, 30 -- the battery indicator climbs steadily, with no need for a cable to connect the bus to the plate. The underlying technology was developed by Winduction, a spinoff company of ETH Zurich, a public university in Switzerland.

By CAS DataLoggers engineering Most workers already know that proper grounding is a fundamental safety precaution for all kinds of electrical equipment. However, it's less well known that while grounding can prevent and resolve many safety and power issues, improper grounding can create problems in data logging, data acquisition, and measurement and control systems.

Stratasys recently launched its new F870 FDM system, a large-format additive manufacturing platform designed for industrial manufacturers, automotive OEMs, and aerospace and defense production lines looking to scale production on the factory floor.

The aging brain is often viewed through a lens of cognitive decline, with older adults seen as compensating for their fading memory. New research in the peer-reviewed journal Perspectives on Psychological Science challenges that view. Drawing evidence from molecular biology and neuroimaging, researchers at the University of Arizona argue that late-life cognition is a natural phase of human development, one that prioritizes wisdom over details.

By Krista Conger, Stanford Medicine For centuries, scientists have thought of the brain as a single, unified organ, but new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.
