Scientists genetically engineer houseplant to remove carcinogens from air

Published

on

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 wins another award critics will absolutely despise

Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.

Tesla just won another award that critics will absolutely despise, as it has been recognized once again as the company with the most sustainable supply chain.

Tesla has once again proven its critics wrong, securing the number one spot on the 2026 Lead the Charge Auto Supply Chain Leaderboard for the second consecutive year, Lead the Charge rankings show.

This independent ranking, produced by a coalition of environmental, human rights, and investor groups including the Sierra Club, Transport & Environment, and others, evaluates 18 major automakers on their efforts to build equitable, sustainable, and fossil-free supply chains for electric vehicles.

Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.

Perhaps the most impressive achievement came in the batteries subsection, where Tesla posted a massive +20-point jump to reach 51 percent, becoming the first automaker ever to surpass 50 percent in this critical area.

Tesla achieved this milestone through transparency, fully disclosing Scope 3 emissions breakdowns for battery cell production and key materials like lithium, nickel, cobalt, and graphite.

The company also requires suppliers to conduct due diligence aligned with OECD guidelines on responsible sourcing, which it has mentioned in past Impact Reports.

While Tesla leads comfortably in climate and environmental performance, it scores 48 percent in human rights and responsible sourcing, slightly behind Ford’s 49 percent.

The company made notable gains in workers’ rights remedies, but has room to improve on issues like Indigenous Peoples’ rights.

Overall, the leaderboard highlights that a core group of leaders, Tesla, Ford, Volvo, Mercedes, and Volkswagen, are advancing twice as fast as their peers, proving that cleaner, more ethical EV supply chains are not just possible but already underway.

For Tesla detractors who claim EVs aren’t truly green or that the company cuts corners, this recognition from sustainability-focused NGOs delivers a powerful rebuttal.

Tesla’s vertical integration, direct supplier contracts, low-carbon material agreements (like its North American aluminum deal with emissions under 2kg CO₂e per kg), and raw materials reporting continue to set the industry standard.

As the world races toward electrification, Tesla isn’t just building cars; it’s building a more responsible future.

Tesla Full Self-Driving likely to expand to yet another Asian country

“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this],” Richi Hashimoto, president of Tesla’s Japanese subsidiary, said.

Tesla Full Self-Driving is likely to expand to yet another Asian country, as one country seems primed for the suite to head to it for the first time.

The launch of Full Self-Driving in yet another country this year would be a major breakthrough for Tesla as it continues to expand the driver-assistance program across the world. Bureaucratic red tape has held up a lot of its efforts, but things are looking up in some regions.

Tesla is poised to transform Japan’s roads with Full Self-Driving (FSD) technology by 2026.

Richi Hashimoto, president of Tesla’s Japanese subsidiary, announced the ambitious timeline, building on successful employee test drives that began in 2025 and earned positive media reviews. Test drives, initially limited to the Model 3 since August 2025, expanded to the Model Y on March 5.

Once regulators approve, Over-the-Air (OTA) software updates could activate FSD across roughly 40,000 Teslas already on Japanese roads. Japan’s orderly traffic and strict safety culture make it an ideal testing ground for autonomous driving.

Hashimoto said:

“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this].”

The push aligns with Hashimoto’s leadership, which has been credited for Tesla’s sales turnaround.

In 2025, Tesla delivered a record 10,600 vehicles in Japan — a nearly 90% jump from the prior year and the first time exceeding 10,000 units annually.

The strategy shifted from online-only sales to adding 29 physical showrooms in high-traffic malls, plus staff training and attractive financing offers launched in January 2026. Tesla also plans to expand its Supercharger network to over 1,000 points by 2027, boosting accessibility.

This Japanese momentum reflects Tesla’s broader international expansion. In Europe, Giga Berlin produced more than 200,000 vehicles in 2025 despite a temporary halt, supplying over 30 markets with plans for sequential production growth in 2026 and battery cell manufacturing by 2027.

While regional EV sales faced headwinds, the factory remains a cornerstone for Model Y deliveries across the continent.

In Asia, Giga Shanghai continues to be recognized as Tesla’s powerhouse. China, the company’s largest market, saw January 2026 deliveries from the plant rise 9 percent year-over-year to 69,129 units, with affordable new models expected later this year.

FSD advancements, already progressing in the U.S. and South Korea, are slated for Europe and further Asian rollout, complementing plans to expand Cybercab and Optimus to new markets as well.

With OTA-enabled autonomy on the horizon and retail strategies paying dividends, Tesla is strengthening its footprint from Tokyo showrooms to Berlin assembly lines and Shanghai exports. As Hashimoto continues to push Tesla forward in Japan, the company’s global vision for sustainable, self-driving mobility gains traction across Europe and Asia.

Tesla has shipped out an update for its vehicles that was caused specifically by a California lawsuit that threatened the company’s ability to sell cars because of how it named its driver assistance suite.

Tesla shipped out Software Update 2026.2.9 starting last week; we received it already, and it only brings a few minor changes, mostly related to how things are referenced.

“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”

The following changes came to Tesla vehicles in the update:

  • Navigate on Autopilot has now been renamed to Navigate on Autosteer
  • FSD Computer has been renamed to AI Computer

Tesla faced a 30-day sales suspension in California after the state’s Department of Motor Vehicles stated the company had to come into compliance regarding the marketing of its automated driving features.

The agency confirmed on February 18 that it had taken a “corrective action” to resolve the issue. That corrective action was renaming certain parts of its ADAS.

Tesla discontinued its standalone Autopilot offering in January and ramped up the marketing of Full Self-Driving Supervised. Tesla had said on X that the issue with naming “was a ‘consumer protection’ order about the use of the term ‘Autopilot’ in a case where not one single customer came forward to say there’s a problem.”

It is now compliant with the wishes of the California DMV, and we’re all dealing with it now.

This was the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” names. Previous Transportation Secretary Pete Buttigieg was one of those federal-level employees who had an issue with the names “Autopilot” and “Full Self-Driving.”

Tesla sued the California DMV over the ruling last week.
