Scientists create bio-engineered mushroom that generates renewable energy
A mushroom has been turned into a renewable energy generator using 3D printed materials and bacteria. In a paper published by the journal Nano Letters, scientists from the Stevens Institute of Technology in Hoboken, New Jersey detailed their experiment wherein strands of graphene were intertwined with cyanobacterial cells on a mushroom cap to capture 65 nanoamps of power. While this amount of power is a fraction of what would be needed to power even an LED, the initial results are promising for further development as a source of renewable energy.
What are Cyanobacteria?
Cyanobacteria, more commonly known as “blue-green algae”, are aquatic, photosynthetic bacteria that have been around for about 3.5 billion years. In addition to the energy produced by photosynthesis, cyanobacteria also produce oxygen, and their ancient ancestors are credited with producing the original oxygen in our atmosphere. These bacteria are further responsible for the origin of plants – the chloroplasts that enable photosynthesis are actually cyanobacterium living in plant cells.
When these bacteria photosynthesize, a fraction of the electrons resulting from the process are released into the surrounding environment. This process of light-induced electric current, termed “photocurrent”, is not very efficient in nature. However, the scientists in this experiment designed a 3D-printable mixture with the bacteria which made the distribution of cells more efficient for photocurrent generation and collection. After being printed onto a mushroom cap, the photocurrent produced was eight times greater than what is produced naturally.
Other Materials
Graphene is a semimetal form of carbon with electrical conductivity and a very thin size. In fact, it’s one of the thinnest materials ever produced. Due to these properties, it was chosen as the base of the 3D printed ink to collect the electricity from the cyanobacteria placed on the mushroom cap. Mushrooms were chosen first to provide a surface and nutrients for the cyanobacteria to grow, and second, they enabled the bacteria to last several days longer compared to other bases and materials.
By accessing and augmenting the unique properties of both the bacteria and nanomaterials (graphene), the scientists in this study have created a new functional bio-hybrid system. With their proof-of-concept “bionic” mushroom, they are hopeful their research can be used to expand to include more bio-hybrid applications. The bacteria themselves have several other properties which can be integrated for purposes such as glowing identification tags for medical use, toxin sensing, and fuel production.
The Future is Now
Cyanobacteria are already being used for other “green” projects besides energy generation, namely in removing CO2 from the air as a result of manufacturing. In one prominent example, Lennaeus University in Sweden has created a system of pushing gases produced in cement production through water bags full of cyanobacteria called the Algoland project. Through this process, nearly all of the CO2 is scrubbed from the emissions using the bacteria’s natural photosynthesis. Other natural limitations of the bacteria are being addressed by projects using techniques such as gene editing for more efficient CO2 conversion and rate of growth.

Tesla Model 3 named New Zealand’s best passenger car of 2025
Tesla flipped the switch on Full Self-Driving (Supervised) in September, turning every Model 3 and Model Y into New Zealand’s most advanced production car overnight.
The refreshed Tesla Model 3 has won the DRIVEN Car Guide AA Insurance NZ Car of the Year 2025 award in the Passenger Car category, beating all traditional and electric rivals.
Judges praised the all-electric sedan’s driving dynamics, value-packed EV tech, and the game-changing addition of Full Self-Driving (Supervised) that went live in New Zealand this September.
Why the Model 3 clinched the crown
DRIVEN admitted they were late to the “Highland” party because the updated sedan arrived in New Zealand as a 2024 model, just before the new Model Y stole the headlines. Yet two things forced a re-evaluation this year.
First, experiencing the new Model Y reminded testers how many big upgrades originated in the Model 3, such as the smoother ride, quieter cabin, ventilated seats, rear touchscreen, and stalk-less minimalist interior. Second, and far more importantly, Tesla flipped the switch on Full Self-Driving (Supervised) in September, turning every Model 3 and Model Y into New Zealand’s most advanced production car overnight.
FSD changes everything for Kiwi buyers
The publication called the entry-level rear-wheel-drive version “good to drive and represents a lot of EV technology for the money,” but highlighted that FSD elevates it into another league. “Make no mistake, despite the ‘Supervised’ bit in the name that requires you to remain ready to take control, it’s autonomous and very capable in some surprisingly tricky scenarios,” the review stated.
-->At NZ$11,400, FSD is far from cheap, but Tesla also offers FSD (Supervised) on a $159 monthly subscription, making the tech accessible without the full upfront investment. That’s a game-changer, as it allows users to access the company’s most advanced system without forking over a huge amount of money.

Tesla starts rolling out FSD V14.2.1 to AI4 vehicles including Cybertruck
FSD V14.2.1 was released just about a week after the initial FSD V14.2 update was rolled out.
It appears that the Tesla AI team burned the midnight oil, allowing them to release FSD V14.2.1 on Thanksgiving. The update has been reported by Tesla owners with AI4 vehicles, as well as Cybertruck owners.
For the Tesla AI team, at least, it appears that work really does not stop.
FSD V14.2.1
Initial posts about FSD V14.2.1 were shared by Tesla owners on social media platform X. As per the Tesla owners, V14.2.1 appears to be a point update that’s designed to polish the features and capacities that have been available in FSD V14. A look at the release notes for FSD V14.2.1, however, shows that an extra line has been added.
“Camera visibility can lead to increased attention monitoring sensitivity.”
Whether this could lead to more drivers being alerted to pay attention to the roads more remains to be seen. This would likely become evident as soon as the first batch of videos from Tesla owners who received V14.21 start sharing their first drive impressions of the update. Despite the update being released on Thanksgiving, it would not be surprising if first impressions videos of FSD V14.2.1 are shared today, just the same.
-->Rapid FSD releases
What is rather interesting and impressive is the fact that FSD V14.2.1 was released just about a week after the initial FSD V14.2 update was rolled out. This bodes well for Tesla’s FSD users, especially since CEO Elon Musk has stated in the past that the V14.2 series will be for “widespread use.”
FSD V14 has so far received numerous positive reviews from Tesla owners, with numerous drivers noting that the system now drives better than most human drivers because it is cautious, confident, and considerate at the same time. The only question now, really, is if the V14.2 series does make it to the company’s wide FSD fleet, which is still populated by numerous HW3 vehicles.

Waymo rider data hints that Tesla’s Cybercab strategy might be the smartest, after all
These observations all but validate Tesla’s controversial two-seat Cybercab strategy, which has caught a lot of criticism since it was unveiled last year.
Toyota Connected Europe designer Karim Dia Toubajie has highlighted a particular trend that became evident in Waymo’s Q3 2025 occupancy stats. As it turned out, 90% of the trips taken by the driverless taxis carried two or fewer passengers.
These observations all but validate Tesla’s controversial two-seat Cybercab strategy, which has caught a lot of criticism since it was unveiled last year.
Toyota designer observes a trend
Karim Dia Toubajie, Lead Product Designer (Sustainable Mobility) at Toyota Connected Europe, analyzed Waymo’s latest California Public Utilities Commission filings and posted the results on LinkedIn this week.
“90% of robotaxi trips have 2 or less passengers, so why are we using 5-seater vehicles?” Toubajie asked. He continued: “90% of trips have 2 or less people, 75% of trips have 1 or less people.” He accompanied his comments with a graphic showing Waymo’s occupancy rates, which showed 71% of trips having one passenger, 15% of trips having two passengers, 6% of trips having three passengers, 5% of trips having zero passengers, and only 3% of trips having four passengers.
The data excludes operational trips like depot runs or charging, though Toubajie pointed out that most of the time, Waymo’s massive self-driving taxis are really just transporting 1 or 2 people, at times even no passengers at all. “This means that most of the time, the vehicle being used significantly outweighs the needs of the trip,” the Toyota designer wrote in his post.
-->Cybercab suddenly looks perfectly sized
Toubajie gave a nod to Tesla’s approach. “The Tesla Cybercab announced in 2024, is a 2-seater robotaxi with a 50kWh battery but I still believe this is on the larger side of what’s required for most trips,” he wrote.
With Waymo’s own numbers now proving 90% of demand fits two seats or fewer, the wheel-less, lidar-free Cybercab now looks like the smartest play in the room. The Cybercab is designed to be easy to produce, with CEO Elon Musk commenting that its product line would resemble a consumer electronics factory more than an automotive plant. This means that the Cybercab could saturate the roads quickly once it is deployed.
While the Cybercab will likely take the lion’s share of Tesla’s ride-hailing passengers, the Model 3 sedan and Model Y crossover would be perfect for the remaining 9% of riders who require larger vehicles. This should be easy to implement for Tesla, as the Model Y and Model 3 are both mass-market vehicles.
