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 gets bold Robotaxi prediction from Wall Street firm
Last week, Andrew Percoco took over Tesla analysis for Morgan Stanley from Adam Jonas, who covered the stock for years. Percoco seems to be less optimistic and bullish on Tesla shares, while still being fair and balanced in his analysis.
Tesla (NASDAQ: TSLA) received a bold Robotaxi prediction from Morgan Stanley, which anticipates a dramatic increase in the size of the company’s autonomous ride-hailing suite in the coming years.
Last week, Andrew Percoco took over Tesla analysis for Morgan Stanley from Adam Jonas, who covered the stock for years. Percoco seems to be less optimistic and bullish on Tesla shares, while still being fair and balanced in his analysis.
Percoco dug into the Robotaxi fleet and its expansion in the coming years in his latest note, released on Tuesday. The firm expects Tesla to increase the Robotaxi fleet size to 1,000 vehicles in 2026. However, that’s small-scale compared to what they expect from Tesla in a decade.
Tesla expands Robotaxi app access once again, this time on a global scale
By 2035, Morgan Stanley believes there will be one million Robotaxis on the road across multiple cities, a major jump and a considerable fleet size. We assume this means the fleet of vehicles Tesla will operate internally, and not including passenger-owned vehicles that could be added through software updates.
He also listed three specific catalysts that investors should pay attention to, as these will represent the company being on track to achieve its Robotaxi dreams:
- Opening Robotaxi to the public without a Safety Monitor. Timing is unclear, but it appears that Tesla is getting closer by the day.
- Improvement in safety metrics without the Safety Monitor. Tesla’s ability to improve its safety metrics as it scales miles driven without the Safety Monitor is imperative as it looks to scale in new states and cities in 2026.
- Cybercab start of production, targeted for April 2026. Tesla’s Cybercab is a purpose-built vehicle (no steering wheel or pedals, only two seats) that is expected to be produced through its state-of-the-art unboxed manufacturing process, offering further cost reductions and thus accelerating adoption over time.
Robotaxi stands to be one of Tesla’s most significant revenue contributors, especially as the company plans to continue expanding its ride-hailing service across the world in the coming years.
Its current deployment strategy is controlled and conservative to avoid any drastic and potentially program-ruining incidents.
So far, the program, which is active in Austin and the California Bay Area, has been widely successful.

Tesla Model Y L is gaining momentum in China’s premium segment
This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.
Tesla’s domestic sales in China held steady in November with around 73,000 units delivered, but a closer look at the Model Y L’s numbers hints at an emerging shift towards pricier variants that could very well be boosting average selling prices and margins.
This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.
Tesla China’s November domestic numbers
Data from the a Passenger Car Association (CPCA) indicated that Tesla China saw domestic deliveries of about 73,000 vehicles in November 2025. This number included 34,000 standard Model Y units, 26,000 Model 3 units, and 13,000 Model Y L units, as per industry watchers.
This means that the Model Y L accounted for roughly 27% of Tesla China’s total Model Y sales, despite the variant carrying a ~28% premium over the base RWD Model Y that is estimated to have dominated last year’s mix.
As per industry watcher @TSLAFanMtl, this suggests that Tesla China’s sales have moved towards more premium variants this year. Thus, direct year-over-year sales comparisons might miss the bigger picture. This is true even for the regular Model Y, as another premium trim, the Long Range RWD variant, was also added to the lineup this 2025.
November 2025 momentum
While Tesla China’s overall sales this year have seen challenges, the Model Y and Model 3 have remained strong sellers in the country. This is especially impressive as the Model Y and Model 3 are premium-priced vehicles, and they compete in the world’s most competitive electric vehicle market. Tesla China is also yet to roll out the latest capabilities of FSD in China, which means that its vehicles in the country could not tap into their latest capabilities yet.
Aggregated results from November suggest that the Tesla Model Y took the crown as China’s #1 best-selling SUV during the month, with roughly 34,000 deliveries. With the Model Y L, this number is even higher. The Tesla Model 3 also had a stellar month, seeing 25,700 deliveries during November 2025.

Tesla Cybertruck earns IIHS Top Safety Pick+ award
To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.
The Tesla Cybertruck has achieved the Insurance Institute for Highway Safety’s (IIHS) highest honor, earning a Top Safety Pick+ rating for 2025 models built after April 2025.
The full-size electric pickup truck’s safety rating is partly due to the vehicle’s strong performance in updated crash tests, superior front crash prevention, and effective headlights, among other factors. To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.
Cybertruck’s IIHS rating
As per the IIHS, beginning with 2025 Cybertruck models built after April 2025, changes were made to the front underbody structure and footwell to improve occupant safety in driver-side and passenger-side small overlap front crashes. The moderate overlap front test earned a good rating, and the updated side impact test also received stellar marks.
The Cybertruck’s front crash prevention earned a good rating in pedestrian scenarios, with the standard Collision Avoidance Assist avoiding collisions in day and night tests across child, adult crossing, and parallel paths. Headlights with high-beam assist compensated for limitations, contributing to the top award.
Safest and most autonomous pickup
The Cybertruck is one of only two full-size pickups to receive the IIHS’ Top Safety Pick + rating. It is also the only one equipped with advanced self-driving features via Tesla’s Full Self-Driving (Supervised) system. Thanks to FSD, the Cybertruck can navigate inner city streets and highways on its own with minimal supervision, adding a layer of safety beyond passive crash protection.
Community reactions poured in, with users praising the vehicle’s safety rating amidst skepticism from critics. Tesla itself highlighted this by starting its X post with a short clip of a Cybertruck critic who predicted that the vehicle will likely not pass safety tests. The only question now is, of course, if the vehicle’s Top Safety Pick+ rating from the IIHS will help the Cybertruck improve its sales.
