NASA rover tech looks set to revolutionize the humble bicycle tire

The humble bicycle tire could be about to undergo a dramatic transformation after a California-based startup this week unveiled a durable space-age tire that never goes flat.

Called METL, the design of the next-generation bicycle tire is based on technology developed by NASA that is aimed at enhancing the resilience of future lunar and Martian rovers.

SMART Tire Company

The SMART (Shape Memory Alloy Radial Technology) Tire Company was formed last year with the central aim of commercializing a new category of airless tire invented for future space missions.

Made from a nickel-titanium alloy called NiTinol+, SMART describes its new tire as a “light, flexible, space-age metal that never goes flat, but still rides smooth.” It believes the material can become a permanent part of future bicycles, with design variations making it suitable for other kinds of vehicles, too.

The special shape-memory material gives the tire the ability to expand, contract, bend, or unbend at a rapid rate before quickly regaining its original shape. Even better, there’s no prospect of a puncture, and you’ll never have to inflate it.

Made in gold, silver, and metallic blue, the METL bike tire features a futuristic look and feel.

“Cyclists will not be able to wait to get their hands on these very cool-looking, space-age METL tires,” Earl Cole, CEO of SMART, said in a release. “The unique combination of these advanced materials, coupled with a next generation, eco-friendly design make for a revolutionary product.”

The METL tire will be available for cyclists in early 2022. Updates regarding the launch can be found via the company’s website or Twitter account.

“Shape memory alloys look extremely promising in revolutionizing the entire terrestrial tire industry,” said NASA engineer Santo Padula, adding, “And that’s just the tip of the iceberg.”

Indeed, SMART says it’s intent on taking on the $250 billion global tire market with the aim of becoming the next great American tire company, “bringing smarter and cleaner solutions to the future of transportation.”

SMART’s METL tire comes out of a partnership with NASA’s Glenn Research Center as part of an initiative geared toward commercializing some of the space agency’s innovations.

Intel just boosted gaming performance by up to 155%
A tray of Intel Core Ultra CPUs.

Intel's engineers once again managed to introduce significant improvements in the latest driver update -- but this time, it's not the discrete graphics cards that received a boost. Instead, the recent patch targets integrated Intel Arc GPUs found in Intel Core Ultra processors, which are some of Intel's top CPUs for laptops. This update adds support for a couple of games, but more importantly, it boosts gaming performance by as much as 155%.

For starters, the new 31.0.101.5333 WHQL driver adds support for Last Epoch and Sea of Thieves, more precisely, the DX 12 update. This applies both to the Intel Arc A-series, meaning dedicated GPUs, and to the Core Ultra chips. Next, we have a slew of performance improvements in DX11 games.

Microsoft might end one of the most annoying GPU wars
Three RTX 4080 cards sitting on a pink background.

The never-ending battle between AMD, Nvidia, and Intel doesn't just involve their graphics cards -- it also stretches to their respective upscaling solutions. It's not all about performance, either, but also the number of games that support them. Microsoft aims to streamline and unify these upscalers, making it easier for game devs to add support for every GPU vendor.

The main issue with having three different upscaling solutions lies not just in how well they all perform in relation to each other (although that's pretty interesting, too), but in how many games can support them. After all, what's the point in DLSS, FSR, and XeSS, if they're not available in too many games? This is where Microsoft's new API, dubbed DirectSR, might come in handy.
