Scientists genetically engineer houseplant to remove carcinogens from air
Scientists at the civil and environmental engineering department at the University of Washington have genetically modified a common houseplant to break down toxic molecules present in chlorinated water and gasoline. The plant, “pothos ivy”, was engineered to express a protein called 2E1 which enables the breakdown of benzene and chloroform into components the plant can use for its own needs. The targeted chemicals are found in small amounts inside typical households, building up over time, but the size of their molecules is too small to be caught by HEPA filters. Since exposure to these chemicals has been linked to cancer, this scientific accomplishment is good news for human health.
In their study published on December 19, 2018 in the journal Environmental Science & Technology, researchers Long Zhang, Ryan Routsong, and Stuart E. Strand described the process they used to modify the pothos ivy plant. The plant was chosen because it was robust and able to grow under many different conditions, and the protein used – P450 2E1, “2E1” for short – is naturally present in all mammals. In humans, 2E1 is in the liver and only turns on to break down alcohol, thus it’s not helpful for breaking down air pollutants. For this reason, the team’s work was focused on making its functionality available outside of the body – they call it a “green liver” concept.
A synthetic version of the 2E1 protein occurring in rabbits was introduced to the pothos ivy so that every cell expressed it. In a test tube trial performed after the genetic modification, chloroform concentration dropped 82 percent after three days, undetectable by six days, and the benzene concentration dropped 75 percent by day eight in vials containing the plants and respective gases. To achieve the benefits of the modified functionality in a household setting, the chemicals will need to be moved to where the plant is located. “If you had a plant growing in the corner of a room, it will have some effect in that room,” Stuart Strand, one of the scientist in the study, said. “But without air flow, it will take a long time for a molecule on the other end of the house to reach the plant.”
Benzene is a common industrial chemical used to make plastics, dyes, detergents, and pesticides, among other things, and is generally found in both rural and urban areas. Its links to cancer are very clear – the most common being leukemia – which has led to significant regulation. While the amount most are exposed to is very low, over time it can build up, especially in areas with heavy traffic, cigarette fumes, and low ventilation. Chloroform is a chemical used that can be released into the air when chlorine is used to clean drinking water, waste water, and swimming pools. Although no direct association between cancer and inhaled exposure to chloroform, the Environmental Protection Agency (EPA) considers it to be a probable human carcinogen due to studies linking high exposure via oral ingestion to cancer.
The process of engineering the plant to function as desired took the team over two years, a significant amount of time compared to the months-long processes of other similar modification projects. However, the time spent was considered to be worthwhile due to both the results achieved and the hardiness of the plant used. They are now working to add the breakdown of formaldehyde to the plant’s capabilities using a different protein. Formaldehyde is a substance present in most building products and tobacco smoke that is also linked to cancer, asthma, and allergies.

Tesla launches in India with Model Y, showing pricing will be biggest challenge
Tesla finally got its Model Y launched in India, but it will surely come at a price for consumers.

Tesla has officially launched in India following years of delays, as it brought its Model Y to the market for the first time on Tuesday.
However, the launch showed that pricing is going to be its biggest challenge. The all-electric Model Y is priced significantly higher than in other major markets in which Tesla operates.
On Tuesday, Tesla’s Model Y went up for sale for 59,89,000 rupees for the Rear-Wheel Drive configuration, while the Long Range Rear-Wheel Drive was priced at 67,89,000.
This equates to $69,686 for the RWD and $78,994 for the Long Range RWD, a substantial markup compared to what these cars sell for in the United States.
🚨 Here’s the difference in price for the Tesla Model Y in the U.S. compared to India.

Deliveries are currently scheduled for the third quarter, and it will be interesting to see how many units they can sell in the market at this price point.
The price includes tariffs and additional fees that are applied by the Indian government, which has aimed to work with foreign automakers to come to terms on lower duties that increase vehicle cost.
Tesla Model Y seen testing under wraps in India ahead of launch
There is a chance that these duties will be removed, which would create a more stable and affordable pricing model for Tesla in the future. President Trump and Indian Prime Minister Narendra Modi continue to iron out those details.
Maharashtra Chief Minister Devendra Fadnavis said to reporters outside the company’s new outlet in the region (via Reuters):
“In the future, we wish to see R&D and manufacturing done in India, and I am sure at an appropriate stage, Tesla will think about it.”
It appears to be eerily similar to the same “game of chicken” Tesla played with Indian government officials for the past few years. Tesla has always wanted to enter India, but was unable to do so due to these import duties.
India wanted Tesla to commit to building a Gigafactory in the country, but Tesla wanted to test demand first.
It seems this could be that demand test, and the duties are going to have a significant impact on what demand will actually be.

Tesla ups Robotaxi fare price to another comical figure with service area expansion
Tesla upped its fare price for a Robotaxi ride from $4.20 to, you guessed it, $6.90.

Tesla has upped its fare price for the Robotaxi platform in Austin for the first time since its launch on June 22. The increase came on the same day that Tesla expanded its Service Area for the Robotaxi ride-hailing service, offering rides to a broader portion of the city.
The price is up from $4.20, a figure that many Tesla fans will find amusing, considering CEO Elon Musk has used that number, as well as ’69,’ as a light-hearted attempt at comedy over the past several years.
Musk confirmed yesterday that Tesla would up the price per ride from that $4.20 point to $6.90. Are we really surprised that is what the company decided on, as the expansion of the Service Area also took effect on Monday?
But the price is now a princely $6.90, as foretold in the prophecy 😂

The Service Area expansion was also somewhat of a joke too, especially considering the shape of the new region where the driverless service can travel.
I wrote yesterday about how it might be funny, but in reality, it is more of a message to competitors that Tesla can expand in Austin wherever it wants at any time.
Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors
It was only a matter of time before the Robotaxi platform would subject riders to a higher, flat fee for a ride. This is primarily due to two reasons: the size of the access program is increasing, and, more importantly, the service area is expanding in size.
Tesla has already surpassed Waymo in Austin in terms of its service area, which is roughly five square miles larger. Waymo launched driverless rides to the public back in March, while Tesla’s just became available to a small group in June. Tesla has already expanded it, allowing new members to hail a ride from a driverless Model Y nearly every day.
The Robotaxi app is also becoming more robust as Tesla is adding new features with updates. It has already been updated on two occasions, with the most recent improvements being rolled out yesterday.

Tesla Model Y and Model 3 dominate U.S. EV sales despite headwinds
Tesla’s two mainstream vehicles accounted for more than 40% of all EVs sold in the United States in Q2 2025.

Tesla’s Model Y and Model 3 remained the top-selling electric vehicles in the U.S. during Q2 2025, even as the broader EV market dipped 6.3% year-over-year.
The Model Y logged 86,120 units sold, followed by the Model 3 at 48,803. This means that Tesla’s two mainstream vehicles accounted for 43% of all EVs sold in the United States during the second quarter, as per data from Cox Automotive.
Tesla leads amid tax credit uncertainty and a tough first half
Tesla’s performance in Q2 is notable given a series of hurdles earlier in the year. The company temporarily paused Model Y deliveries in Q1 as it transitioned to the production of the new Model Y, and its retail presence was hit by protests and vandalism tied to political backlash against CEO Elon Musk. The fallout carried into Q2, yet Tesla’s two mass-market vehicles still outsold the next eight EVs combined.
Q2 marked just the third-ever YoY decline in quarterly EV sales, totaling 310,839 units. Electric vehicle sales, however, were still up 4.9% from Q1 and reached a record 607,089 units in the first half of 2025. Analysts also expect a surge in Q3 as buyers rush to qualify for federal EV tax credits before they expire on October 1, Cox Automotive noted in a post.
Legacy rivals gain ground, but Tesla holds its commanding lead
General Motors more than doubled its EV volume in the first half of 2025, selling over 78,000 units and boosting its EV market share to 12.9%. Chevrolet became the second-best-selling EV brand, pushing GM past Ford and Hyundai. Tesla, however, still retained a commanding 44.7% electric vehicle market share despite a 12% drop in in Q2 revenue, following a decline of almost 9% in Q1.
Incentives reached record highs in Q2, averaging 14.8% of transaction prices, roughly $8,500 per vehicle. As government support winds down, the used EV market is also gaining momentum, with over 100,000 used EVs sold in Q2.
