Researchers test ‘biohybrid robots’ that merge living tissue with machines
Researchers from the University of Tokyo have fused together living tissue from a rat with mechanical components to create a biohybrid system that can mimic human fingers.
In the video shared by National Geographic, the finger-like system can be seen performing precise tasks that require dexterity and are traditionally more difficult for robots to accomplish. Scientists that participated in the study say that these small movements will lay the foundation for more complex human-robots.
“If we can combine more of these muscles into a single device, we should be able to reproduce the complex muscular interplay that allows hands, arms, and other parts of the body to function,” said Yuya Morimoto, lead author of the research project.
The research team looked into biohybrid systems because living tissue combined with man-made machines can achieve better movement and flexibility when compared to traditional robots made from plastic and metal. The increase of movement and flexibility will allow robots to better perform precision tasks.
The research team grew their robot’s muscles by layering rat tissue on top of a robotic frame. The living cells used in these types of robots usually come from the heart or skeletal muscle of rats or chickens that are bonded to a material that is non-toxic to the cells. To ensure that the cells function properly when stimulated, researchers use micropatterning techniques to align the cells in an order that’s conducive to movement.
However, due to the short lifespan of the living tissue when intermixed with the robotic system – after a period of time, the muscles would shrink making them useless – co-author of the project, Shoji Takeuchi, layered the muscles next to each other to create an antagonistic pair. An antagonistic pair is when one muscle contracts while the other one expands, similar to the relationship between human biceps and triceps. Takeuchi said that antagonistic pairing prevents wear, allowing the muscles to be used for a longer period of time. In the most recent tests, the tissue used in the video lasted just over a week. This muscle pattern also gives the robot a full 90-degree motion.
The research team believes that biohybrid systems could help create adept prosthetics and provide human-like muscles that scientists can test drugs and toxins on, thus reducing the need for animal testing.

There are some limitations to biohybrid robots, however. Biohybrid robots used in the research can only survive and function in water. Electrically stimulating the muscles in water will form bubbles that will eventually degrade the tissue. The research team is looking into genetically modifying the muscle cells to become more resistant to damage and can induce neurons, called motor neurons, that tell the muscle when to move.

Tesla unlocks in-car web conferencing to extend Google Meet, Teams and beyond
Tesla’s Summer Update lets owners join Google Meet, Teams, and Discord calls via cabin camera.
Tesla’s 2026 Summer Update, which just began rolling out to customer vehicles, now links the built-in web browser with the in-cabin camera feed and microphone input, thereby letting owners join video calls on nearly any browser-based service instead of just Zoom.
The change appears in Tesla’s own release notes for software version 2026.26 under “Web Browser,” which states that the vehicle can now use its interior camera and cabin microphone when a website requests access, with permission granted the same way a desktop browser handles it. As NotATeslaApp notes, this feature opens the door to Google Meet, Microsoft Teams, Discord, and other webcam-enabled sites to activate the in-car cabin-facing camera. The feed automatically crops and zooms to center the driver in frame.
Tesla has offered in-car video calling before, but only through a dedicated Zoom app that launched at the end of 2022, a stripped-down browser preloaded with Zoom’s own web client and gated behind Premium Connectivity. Opening the full browser to any camera-requesting site removes that walled garden. Elon Musk first called video conferencing “definitely a future feature” back in 2020, when the pandemic pushed remote meetings into daily life, so this update effectively finishes something Tesla has been promising for six years.
Tesla Summer Update begins rolling out: a look at the new features
The feature keeps the same restrictions that applied to Zoom on Tesla vehicles. It only works while the car is parked; shifting into Drive disables the camera feed, according to the release notes. It is also limited to vehicles running Tesla’s AMD Ryzen infotainment hardware, meaning older Intel-based Model S and Model X units, along with early Model 3 and Model Y builds, don’t get it.
Turning the browser into a general entry point for the in-cabin camera, rather than routing everything through one local app, widens the number of third-party sites that can ask for access, even though Tesla’s permission prompt.
With the Summer update only days into its rollout, be sure to stay with us on TikTok and X to see the latest video demonstrations.

Elon Musk escalated his monthslong feud with Christopher Nolan’s The Odyssey this week, pledging that his own AI video tool will produce a competing version before the year is out. Responding to a fan-made, AI-generated clip of the ancient epic, Musk wrote on X, “Before this year ends, Grok Imagine will make a full-length movie of The Odyssey that is historically accurate and true to the art of Homer.”
In June, Musk quoted an xAI-shared trailer built entirely with Grok Imagine Video 1.5, a two-minute-plus reimagining of The Odyssey styled after a 1970s classical Hollywood epic, and predicted “full movies by the end of the year,” as Teslarati reported at the time. That trailer, built from 36 consistent shots by a single creator, was Musk’s proof of concept. This week’s pledge turns that prediction into a specific commitment, tied directly to Homer’s text rather than a generic demo.

When a fan separately proposed that Musk fund a live-action alternative, to “give Mel Gibson $100 million to film an Odyssey adaptation with painstakingly historically accurate ships, armour, weapons, and casting, with all dialogue taken straight from the original poem and delivered in Homeric Greek,” Musk replied with two words: “I’m down.”
The Grok Imagine pledge lands as the tool’s underlying infrastructure has changed hands. Grok is no longer a standalone product, it folded into SpaceXAI after SpaceX’s acquisition of xAI closed in February, meaning the compute behind any Odyssey production traces back to the same Colossus supercomputers now bundled into SpaceX’s pitch to investors. Musk has separately said SpaceX’s own engineering data is being fed into the next major Grok training run, a two trillion parameter model he’s called the “2T run.”
Whether Grok Imagine can sustain a feature length narrative, rather than a series of impressive individual shots, remains the open question.

Tesla Mobile App gets a new feature that wrap fans are going to love
Tesla’s Summer Update removes the USB drive step from customizing your car’s digital wrap design.
Tesla’s latest 2026 Summer Update quietly closes out one of the more tedious steps in personalizing a Tesla’s digital appearance. Uploading a custom wrap design used to require a USB drive. Now it doesn’t.
The feature is listed in Tesla’s release notes as “Send Custom Wraps from Mobile App.” The company described it plainly: “Skip the USB drive and upload a custom wrap of your car from the mobile app. Instructions for creating a custom wrap here: github.com/teslamotors/custom-wraps.”
The digital wrap tool has been around since Tesla’s 2024 Holiday Update, when it launched for Cybertruck owners first, as Teslarati reported at the time. Getting a design onto the car meant formatting a USB drive, creating a folder named exactly “Wraps,” dropping in PNG files sized between 512×512 and 1024×1024 pixels and under 1 MB each, then plugging the drive in and applying the wrap through Toybox. Tesla expanded the tool to other models and renamed it from “Colorizer” to “Paint Shop” with the 2025 Holiday Update, while also adding license plate and window tint customization alongside the wraps.

The latest Summer Update removes the USB step from that process. Owners will be able to pull a design from wherever they saved it, whether that’s a download from social media or something built from Tesla’s own GitHub templates, and push it to the car directly through the app.

It’s a small fix relative to the rest of this latest release, which also included expanded Grok voice commands, automatic navigation that learns regular routes, and self-driving stats inside the mobile app, all detailed in our rundown of the full Summer Update. The USB requirement was one of the more common complaints about Paint Shop since it launched. Tesla did not say when the wrap upload change would reach individual vehicles, only that the broader update is rolling out now in waves.
