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.

Another Tesla Model 3 variant sold out for January 2026 in China
A look at Tesla China’s order page shows that new Model 3 LR RWD orders now have an estimated delivery date of February 2026.
Another Tesla Model 3 variant in China appears to have sold out for January 2026, with the vehicle now showing an estimated delivery date of February 2026 for new orders. This bodes well for the all-electric sedan, which has maintained notable sales despite more affordable rivals like the Xiaomi SU7 and its crossover sibling, the Model Y.
Model 3 LR RWD joins February 2026 queue
A look at Tesla China’s order page for the all-electric sedan shows that new Model 3 Long Range Rear Wheel Drive orders now have an estimated delivery date of February 2026. Priced from RMB 259,500 ($36,810), the LR RWD sits as the second-lowest-priced trim in Tesla China’s four-variant Model 3 lineup. The move follows a similar delivery timeframe for the Model 3 Performance, which remains the most expensive option for the vehicle, as noted in a CNEV Post report.
The estimated delivery dates of the two remaining Model 3 variants remain unchanged for now. The base RWD version, starting at RMB 235,500, and the LR AWD variant, priced from RMB 285,500, both continue to list estimated delivery times of 4-6 weeks. Tesla China, for its part, has continued to list in-stock Model 3 vehicles and is actively encouraging buyers to select inventory units for delivery before the end of the year.
Model Y delays and policy shifts
Delivery timelines for the Model Y in China are also stretching into 2026. All customized Model Y variants now show February 2026 as their estimated delivery date, except for the entry-level version, which still lists January 2026. Tesla has been urging customers since November to prioritize purchasing inventory vehicles, a push aimed at maximizing year-end deliveries.
Timing matters for Chinese buyers due to upcoming changes in government incentives. China’s new energy vehicle purchase tax exemption will be scaled back in 2026, which means customers who take delivery next year could face higher tax costs compared to those who are able to receive vehicles before the end of the year.
As per data from the China Passenger Car Association, Tesla recorded retail sales of 73,145 vehicles in November, down 0.47% year over year. From January through November, Tesla’s retail sales in China totaled 531,855 units, a 7.37% year-over-year drop.

Wedbush’s Dan Ives sees ‘monster year’ ahead for Tesla amid AI push
In a post on X, the analyst stated that the electric vehicle maker could hit a $3 trillion market cap by the end of 2026 in a bullish scenario.
Wedbush analyst Dan Ives is doubling down on Tesla’s (NASDAQ:TSLA) long-term upside. In a post on X, the analyst stated that the electric vehicle maker could hit a $3 trillion market cap by the end of 2026 in a bullish scenario, thanks to the company’s efforts to develop and push its artificial intelligence programs.
An aggressive valuation upside
Ives, Wedbush’s global head of tech research, stated in his post that Tesla is entering a pivotal period as its autonomy and robotics ambitions move closer to commercialization. He expects Tesla’s market cap to reach $2 trillion in 2026, representing roughly 33% upside from current levels, with a bull case up to a $3 trillion market cap by year-end.
Overall, Ives noted that 2026 could become a “monster year” for TSLA. “Heading into 2026, this marks a monster year ahead for Tesla/Musk as the autonomous and robotics chapter begins. We believe Tesla hits a $2 trillion market cap in 2026 and in a bull case scenario $3 trillion by end of 2026… as the AI chapter takes hold at TSLA,” the analyst wrote.
Ives also reiterated his “Outperform” rating on TSLA stock, as well as his $600 per share price target.
Unsupervised Full-Self Driving tests
Fueling optimism is Tesla’s recent autonomous vehicle testing in Austin, Texas. Over the weekend, at least two Tesla Model Ys were spotted driving on public roads without a safety monitor or any other occupants. CEO Elon Musk later confirmed the footage of one of the vehicles on X, writing in a post that “testing is underway with no occupant in the car.”
It remains unclear whether the vehicle was supported by chase cars or remote monitoring, and Tesla has not disclosed how many vehicles are involved. That being said, Elon Musk stated a week ago that Tesla would be removing its Safety Monitors from its vehicles “within the next three weeks.” Based on the driverless vehicles’ sightings so far, it appears that Musk’s estimate may be right on the mark, at least for now.

Production-ready Tesla Cybercab hits showroom floor in San Jose
Tesla has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements.
Tesla has showcased what appears to be a near-production-ready Cybercab at its Santana Row showroom in San Jose, California, giving visitors the closest look yet at the autonomous two-seater’s refined design.
Based on photos of the near-production-ready vehicle, the electric vehicle maker has implemented subtle but significant updates to both the Cybercab’s exterior and interior elements, making the vehicle look more polished and seemingly more comfortable than its prototypes from last year.
Exterior and interior refinements
The updated Cybercab, whose photos were initially shared by Tesla advocate Nic Cruz Patane, now features a new frameless window design, an extended bottom splitter on the front bumper, and a slightly updated rear hatch. It also includes a production-spec front lightbar with integrated headlights, new wheel covers, and a license plate bracket.
Notably, the vehicle now has two windshield wipers instead of the prototype’s single unit, along with powered door struts, seemingly for smoother opening of its butterfly doors. Inside, the Cybercab now sports what appears to be a redesigned dash and door panels, updated carpet material, and slightly refined seat cushions with new center cupholders. Its legroom seems to have gotten slightly larger as well.
Cybercab sightings
Sightings of the updated Cybercab have been abundant in recent months. At the end of October, the Tesla AI team teased some of the autonomous two-seater’s updates after it showed a photo of the vehicle being driven through an In-N-Out drive-through by employees in Halloween costumes. The photos of the Cybercab were fun, but they were significant, with longtime Tesla watchers noting that the company has a tradition of driving its prototypes through the fast food chain’s drive-throughs.
Even at the time, Tesla enthusiasts noticed that the Cybercab had received some design changes, such as segmented DRLs and headlamps, actual turn signals, and a splitter that’s a lot sharper. Larger door openings, which now seem to have been teasing the vehicle’s updated cabin, were also observed at the time.
