Defense tech startup Mach Industries raised $600 million in a Series C extension, pushing its valuation to $3.7 billion just three months after a $300 million round valued it at $1.8 billion. Backers in both rounds include Ribbit Capital, Infinite Capital, Bedrock Capital and Sequoia. The company makes unmanned military vehicles, including VTOL drones, long-range strike systems and counter-drone tech, from its Huntington Beach, California facility.

Rails 8.0, released in November 2024 with built-in authentication, Solid Queue/Cache/Cable, Kamal 2 deployment and production-ready SQLite, is now down to security-only fixes that end November 7, 2026. Rails 8.1, released in October 2025, is the actively maintained version, while Rails 7.1 and 7.2 have already fallen out of support entirely.

A developer released Solid Objects, an open-source library that replicates the Durable Objects programming model—one identity, one state, one ordered mailbox per object—without requiring a dedicated vendor runtime or daemon. Instead, it runs directly on databases developers already operate, including SQLite, PostgreSQL, and MySQL. The release follows the creator's frustration with vendor lock-in and unpredictable metered billing tied to existing Durable Objects platforms.

Scientists from Karlsruhe Institute of Technology and the University of Tsukuba built a solid-state cooling prototype that uses a shape-memory titanium-nickel film to convert heat directly into the mechanical motion needed to drive elastocaloric cooling, replacing the usual electric actuator. In tests, heating the actuator film to 86°C produced a 4.0 K temperature difference across the cooling device, and swapping in an external 130°C heat source still yielded a 2.2 K span, showing waste heat alone can power the cycle.

After two years of testing electric kitchen composters, a WIRED reviewer found that most devices marketed as composters actually just grind and dehydrate food scraps rather than produce true garden-ready compost. The reviewer's top pick, the Reencle Prime, was singled out as the rare model that yields something closer to actual compost.

Rising electricity demand from AI data centers is spurring investment in solid-state power transformers, which use semiconductor switching instead of the century-old copper-coil design of conventional transformers. Unlike traditional units, which are hand-built and face multi-year delivery backlogs, solid-state versions can be mass-produced using materials like silicon carbide, making them smaller, lighter, and modular. Tech companies building AI infrastructure are especially drawn to them because they suit the direct current power setups increasingly used to run dense racks of AI chips.
