Twitter launches 'new' Tweetdeck as the old version breaks down

If you've been having trouble using Twitter recently, you aren't alone — the service has been having issues ever since it started limiting the number of posts users could view each day. Although many of the platform's issues stabilized over the weekend, Tweetdeck remains broken unless users switch to the beta version of the list aggregator. Now, Twitter is gearing up to solve the issue by making that beta version of Tweetdeck the main version, announcing on Monday that it has "launched a new, improved version of Tweetdeck."

Despite officially launching, this "new" Tweetdeck still calls itself the "Tweetdeck Preview" while in app, and users still need to opt-in to using it in the menu of the original Tweetdeck interface. Even so, switching to the new interface does indeed restore basic Tweetdeck functionality for users that rely on its list aggregation features. Twitter says the process should be fairly straightforward as well, promising that saved searches, lists and columns should carry over instantly. Although Twitter says that the updated preview build should now support Twitter Spaces, polls and other features that were previously missing, it notes that Teams functionality is currently unavailable.

Twitter hasn't officially announced that it's retiring the old version of Tweetdeck, but in a thread discussing the issues a Twitter employee suggested the change would be permanent, stating that they were "migrating everyone to the preview version." 

Although switching to the new version of Tweetdeck potentially resolves the issue, many legacy users may still find themselves without access to the power-user tool in the near future. According to Twitter Support, the feature will become exclusive to Twitter Blue subscribers in the near future, noting that "in 30 days, users must be Verified to access Tweetdeck." It's unclear if that change will be applied to all users in early August, or if all users will have a 30-day trial of the new Tweetdeck before being prompted to subscribe.

The final trailer for 'The Super Mario Bros. Movie' looks more like a game than ever

There was a time when movies based on video games tried to distance themselves from their source material. "This ain't no game," bragged the poster for the 1993's live-action Super Mario Bros. film. Times have changed: The final trailer for The Super Mario Bros. Movie by Illumination leans hard into its origins. This is absolutely a game, it says. See? Here's a scene that looks like New Super Mario Bros. U Deluxe, and another one that looks just like Mario Kart 8 Deluxe.

If you were hoping to hear more of Chris Pratt's Mario voice, you won't find much new here — but the final trailer does give viewers a clear look at the tone the movie is going for. We watch Bowser list off an army of familiar video game enemies. We watch Mario and Donkey Kong use power mushrooms and fire flowers as they run through a training course that looks like a traditional Mario level. We see Mario and Peach race through a brightly rendered Rainbow Road. It looks familiar. It looks fun. And it looks like a game, but with better graphics.

That's no surprise. According to directors Aaron Horvath and Michael Jelenic, Illumination has worked closely with Nintendo to make sure the film feels right. The directors also say that Illumination has improved its lighting and rendering technology to help push Super Mario Bros. Movie to the next level "beyond anything Illumination has ever done."

As for that Mario voice? You'll finally be able to hear the full performance when the film hits theaters next month. The Super Mario Bros. Moviereleases on April 5, 2023.

Legislation to ban government use of facial recognition hits Senate for the third time

Biometric technology may make it easy to unlock your phone, but democratic lawmakers have long cautioned against the use of facial recognition and biometrics by law enforcement. Not only have researchers documented instances of racial and gender bias in such systems, false positives have even led to real instances of wrongful arrest. That's why lawmakers have re-introduced the Facial Recognition and Biometric Technology Act. This actually marks the third time the bill was introduced to the Senate — despite being introduced in 2020 and 2021, the act was never advanced to a vote.

If passed, the Facial Recognition and Biometric Technology Act would outright ban any use of facial recognition or biometric surveillance by the federal government unless that use is explicitly approved by an Act of Congress. That approval itself would be pretty limited: It would need to define who was allowed to use biometric surveillance, the exact type of biometric surveillance they would be using and the specific purpose it would be used for. Approval would also have the burden of further restrictions, such as adhering to minimum accuracy rates that would hopefully avoid false positives in the rare instances when use of the technology is approved.

The bill also hopes to encourage local and state governments to follow its lead, including a clause that would tie some federal funding for local law enforcement to complying with a "substantially similar" ban on facial recognition and biometrics.

While the bill hasn't had much luck making it to the floor of either chamber of congress, some states and local governments have been banning facial recognition technology on their own. In 2020, Portland Oregon put strict guardrails on the use of facial recognition technology. New York State and Massachusetts have also put restrictions on the use of biometrics. Even the IRS walked back plans to use facial recognition for identity verification purposes.

That sounds encouraging for the re-introduced bill, but that momentum isn't universal: Law enforcement still sees biometrics as a useful tool for investigating crime, and the TSA has been testing systems that compare travelers to the photo on their passport or driver's license.

Researchers are using sound-waves and holograms to instantly mold tiny 3D shapes

The idea of growing organs or tissues for medical use still sounds like science fiction — and indeed, it's an incredibly difficult thing to do. 3D-printing technology has shown some promise in the field of biofabrication, but the process is too slow, and often damages the tissue it's working with. Researchers in Germany may have a solution: using holograms and sound fields to rapidly assemble matter in 3D.

The process uses acoustic pressure to mold silica gel microspheres and other materials into complex 3D shapes. Pulling that off isn't easy. The team first had to learn how to create complex, layered holographic shapes that were formed from sound, rather than light — and that takes an incredible amount of computational power. "The digitization of an entire 3D object into ultrasound hologram fields is computationally very demanding and required us to come up with a new computation routine," one of the team's researchers told FastCompany.

Once the hologram is complete, however, it can be used to mold various materials. The shapes the team has made so far aren't very large — measuring less than an inch at the largest — but they are fairly complex. Even more impressive, the fabrication process happens quite quickly: One video included with the published study shows a clear cube with a cloudy liquid made of silica gel microspheres. Moments later, that cloud condenses into the shape of a helix.

Other experiments formed shapes using mouse myoblast cells, and the study's lead author, Kai Melde, told FastCompany that the technology had potential to be used for bioprinting in the future. "Ultrasound is gentle and non-toxic to the cells," Melde explained. "And the remote assembly without contact helps keep things sterile and the cells happy." The study also explores the idea of using the technology for targeted drug delivery and rapid prototyping. For now though, the research stands as an interesting proof of concept for rapid-one-step assembly of 3D objects, and a potential, much faster alternative to 3D printing in the future.

Ford's new AI subsidiary wants to create hands-free, eyes-off driver assist systems

Hate sitting in rush hour traffic? Ford knows you do — and the company is doubling down on developing automated driving technology to help make traffic a little more tolerable. Today, Ford announced the creation of Latitude AI, a wholly owned subsidiary that aims to make driving less stressful, specifically in "bumper-to-bumper traffic or on long stretches of highway."

The idea seems to be to develop a more advanced version of Ford BlueCruise — but without sensors that warn drivers to pay attention if their eyes wander from the road. Ford's announcement instead imagines the system giving drivers an "eyes-off-the-road" experience that can give them "some of their day back."

This isn't the first time Ford has spun off part of its company to focus on automation. Back in 2018, it founded Ford Autonomous Vehicles LLC to focus on developing self-driving car technology. Later, that group was placed under the umbrella of Ford Next, a unit formed in 2021 to help Ford manage startups, new mobility services and manage the company's stake in Argo AI. This new company seems to be a way to continue Argo AI's work following its closure last year: Ford says 550 of Latitude AI's new employees are former Argo AI workers.

Ford previously promised to invest $29 billion in electric and autonomous vehicles by 2025. Forming Latitude AI shows that the company is still serious about the investment, despite Argo AI's closure in 2022. “We believe automated driving technology will help improve safety while unlocking all-new customer experiences that reduce stress and in the future will help free up a driver’s time to focus on what they choose," Latitude AI CEO Sammy Omari said in a company statement.
