Researchers test ‘biohybrid robots’ that merge living tissue with machines

Published

on

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 has brought perhaps the coolest interior feature to its cars in a new update that is rolling out to vehicles now.

The feature will require a newer vehicle that has interior ambient lighting, which is present on the new Model S, Model X, Model 3 “Highland,” and Model Y “Juniper.” The Cybertruck also has ambient lighting strips throughout.

Tesla Model Y’s ambient lighting design changes revealed in leaked video

With the Version 2025.26+ Software Update, Tesla is rolling out a new “Sync Accent Lights w/ Music” feature, which is available on the Tesla Toybox:

To enable the feature, you’ll access the Toybox, choose “Light Sync,” and then choose “Sync Accent Lights w/ Music.”

Although it does not improve the performance of the vehicle, it is yet another example of Tesla making one of the coolest cars out there. This is truly a cool add-on that can be used to impress your friends and family.

Elon Musk’s artificial intelligence startup xAI and the Musk Foundation have been supporting Memphis-Shelby County Schools with HVAC repairs and facility upgrades, while also funding youth programs for students in the area. 

Reports of xAI and the Musk Foundation’s work were recently posted by local news media.

xAI’s school visits lead to facility repairs

Representatives from xAI visited John P. Freeman Optional School, Fairley High School, and Westwood High School, all of which are located near its Colossus supercomputer site, to assess HVAC systems, plumbing, gym facilities, and athletic fields. The visits resulted in a list of priority repairs, some of which were completed in April and May.

In addition to the repairs, xAI also shared a number of initiatives that are planned for students in the area, as stated in a Commercial Appeal report.

“xAI is working on providing STEM workshops for local students, donating equipment to technical training programs, and supporting job fairs to boost employment opportunities. These initiatives reflect xAl’s commitment to fostering education and economic growth in Memphis,” xAI noted in a statement.

Musk Foundation donation

Apart from xAI, the Musk Foundation also donated $350,000 to the Boys & Girls Clubs of Greater Memphis, enabling the reopening of two club sites located at Booker T. Washington High School and Westwood High School. Both locations had closed earlier this year due to lapses in funding. As per xAI, the Musk Foundation’s donation allows clubs to reopen for almost 1,000 students. 

The donation will fund staffing, supplies, and transportation, among others. “Kids are the future of humanity,” Elon Musk said in a statement, adding that students need “every chance to shoot for the stars.”

“We’re honored to support the Boys & Girls Clubs of Greater Memphis in reopening these sites, giving kids in underserved communities the tools to build brighter futures,” Musk said.

The gift was praised by local officials, including Boys & Girls Clubs board chair Michael Garriga, who stated that the “commitment will ensure the youth of our community have the opportunities they need to develop their skills and talents to become successful students and future citizens.”

EV fans urge Tesla to acquire Unplugged Performance for edge in fleet and security industry

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles.

A growing number of Tesla enthusiasts and longtime community voices are calling on the electric vehicle maker to acquire Unplugged Performance, a California-based aftermarket company best known for tuning Tesla vehicles and developing specialized government fleet solutions under its UP.FIT division.

The idea was once considered a niche proposal among EV fans, but it is now gaining serious attention not just as a performance play but as a strategic move to deepen Tesla’s roots in the fleet and security industry. 

A strategic fit

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles, from track-optimized components to visual and aerodynamic upgrades. But in recent years, its UP.FIT division has pivoted toward a more functional future by outfitting Tesla vehicles like Model Ys for police, military, and government use.

That work has sparked growing calls for closer collaboration with Tesla, especially as the EV maker increasingly leans into autonomy, AI, and fleet services as core components of its next chapter.

“I posted this four years ago, but I think it’s more true now than ever,” wrote Whole Mars Catalog, a well-known Tesla investor and FSD Beta tester, on X. “Tesla should buy Unplugged. But not just as a Performance division. What they are doing with UP.FIT unlocks large government and commercial fleet purchases that can improve utilization.”

Tesla fans such as shareholder Sawyer Merritt echoed the sentiment, calling Unplugged a “great fit within Tesla.” adding, “They are literally located directly next to Tesla’s design studio in Hawthorne.”

Enabling the next wave

Supporters of the idea noted that integrating Unplugged into Tesla’s corporate structure could help accelerate the adoption of autonomous technologies in government sectors. With UP.FIT patrol cars already in use across some U.S. police departments, Tesla fans envisioned a future where self-driving Teslas could potentially revolutionize law enforcement, search-and-rescue, and public service logistics.

“Just imagine how autonomous patrol cars could transform policing and bring us into a safer future,” the veteran FSD tester wrote.

The benefits could also extend to Tesla’s existing consumer base. “They also have some incredible products in the works that I think will appeal to many ordinary Tesla drivers — not just those looking for performance or mods. Stuff that’s so good it should have come straight from the design studio next door,” Whole Mars Catalog noted.

Unplugged Performance, founded in 2013, shares not just a product vision with Tesla, but also geography. Its Hawthorne headquarters sits directly adjacent to Tesla’s design studio, and the two companies have maintained a close working relationship over the years. The aftermarket firm has long positioned itself as a “mission-aligned” partner to Tesla.
