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.
Investor's Corner
Tesla’s comfort level taking risks makes the stock a ‘must own,’ firm says

Tesla (NASDAQ: TSLA) had coverage initiated on it by a new firm this week, and analysts said that the company’s comfort level with taking risks makes it a “must own” for investors.
Melius Research and analyst Rob Wertheimer initiated coverage of the stock this week with a $520 price target and a “Buy” rating. The price target is about 20 percent higher than the current trading price as shares closed at $435 on Wednesday, up 1.38 percent on the day.
Wertheimer said in the note to investors that introduced their opinion on Tesla shares that the company has a lot going for it, including a prowess in AI, domination in its automotive division, and an incredible expertise in manufacturing and supply chain.
He wrote:
“We see Tesla shares as a must-own. The disruptive force of AI will wreck multitrillion-dollar industries, starting with auto. Under Musk’s leadership, the company is comfortable taking risks. It has manufacturing scale and supply chain expertise that robotics startups possess more by proxy. It can rapidly improve and scale autonomy in driving, the first major manifestation of AI in the physical world.”
However, there were some drawbacks to the stock, according to Wertheimer, including its valuation, which he believes is “challenging” given its fundamentals. He said the $1 trillion market cap that the company represented was “guesswork,” and not necessarily something that could be outlined on paper.
This has been discussed by other analysts in the past, too. Yale School of Management Senior Associate Dean Jeff Sonnenfeld recently called Tesla the “biggest meme stock we’ve ever seen,” by stating:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Additionally, J.P. Morgan’s Ryan Brinkman said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Some analysts covering Tesla have said they believe the stock is traded on narrative and not necessarily fundamentals.

Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet

Tesla launched its fastest Full Self-Driving Speed Profile with the v14.1.2 Software Update on Wednesday, as “Mad Max” mode has overtaken “Hurry” as the most spirited travel option on FSD.
On Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, teased that the v14.1.2 Software Update would be released to those drivers in the Early Access Program (EAP). He said it was a “much-awaited feature.”
Tesla just teased something crazy with the next Full Self-Driving update
Many people, myself included, believed it would be the introduction of “Banish,” which would be a perfect complement to the Actually Smart Summon (ASS) suite, as it would find a parking spot and park itself after dropping you off at the front door of your destination.
However, Elluswamy’s post on X finished with two emojis: one a race car, the other being smoke behind the car.
FSD v14.1.2, going to early access today, will debut a much awaited feature 🏎️💨

On Wednesday night, we received the v14.1.2 software update to the new Model Y, which revealed that “Mad Max” mode was the new addition:

The release notes state that:
“Introduced new speed profile MAD MAX, which comes with higher speeds and more frequent lane changes than Hurry.”
It is pretty interesting that Tesla would introduce yet another speed profile that is even faster and more aggressive than “Hurry.” Personally, I’ve found Hurry to be realistic in terms of other drivers and their aggressiveness, speed of travel, and overall lane change behavior, especially on interstates.
Mad Max mode will be an interesting adjustment.
Tesla CEO Elon Musk first talked about Mad Max mode back in 2018 in posts on X, first mentioning the feature with the Tesla Semi:

Musk then teased Mad Max mode in 2019 with an early Autopilot update, stating that it would be an ideal option for aggressive traffic seen in places like Los Angeles. There was formerly a mode of the same name back in the late 2010s:
Are you on Mad Max Mode? This may be too meek for places like the LA Freeway …

Now that it’s here, we’ll be testing it very soon and giving you a good idea of what to expect when it releases to others in the coming weeks.

Tesla just teased something crazy with the next Full Self-Driving update

Update 9:56 p.m. ET: We got it…
Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet
Tesla just teased something crazy with the next Full Self-Driving update, which will be released to Early Access Program (EAP) members today.
Tesla just recently released the v14 Full Self-Driving update, and it followed up just a few days later with v14.1.1.
The subsequent release helped refine a handful of things, especially an issue with stuttering at intersections and overall indecisiveness, but it was more of a smoothing over of the initial v14.1 Full Self-Driving release.
However, on Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, said that the company would be releasing v14.1.2 to EAP members today, and that it would “debut a much-awaited feature.”
He followed that up with a racecar emoji and a smoke emoji, potentially hinting toward something speed-related. However, it could mean something totally different.

Some suggested it was potentially a new Speed Profile that could rank above the “Hurry” option, but that seems unnecessary. As far as other features that have been teased, one that definitely comes to mind is the “Banish” feature that was recently teased by CEO Elon Musk.
Banish is essentially the finishing touch to Tesla’s Actually Smart Summon (ASS), which launched earlier this year.
While ASS will bring your car to your location using the Tesla app on your phone, Banish does just the opposite by dropping you off at the door of your destination and finding a parking spot on its own.
Elon Musk teases ‘Banish’ feature to pair perfectly with Summon
This was recently teased by Musk yet again, as he said earlier this month that Full Self-Driving would be capable of it very soon.
Based on what we’ve seen out of v14.1 and v14.1.1, there is some potential that Banish could be released and could be the feature that Elluswamy is hinting toward, although there is no direct evidence of that.
Luckily, I was able to get into the EAP, so as the feature is released and the Release Notes are available, we’ll be able to report on exactly what feature is on the way.
