Electric vehicles are pretty much inevitable at this point, with carmakers, led by all-EV disruptors such as Tesla, transitioning their respective fleets to electric. Yet despite this, there are still a lot of skeptics who argue that electric vehicles do not really do anything useful for the environment. 

A study from the Keck School of Medicine of the University of Southern California has provided some real-world observations about electric vehicles and how they positively impact the environment. The researchers’ study leveraged publicly available datasets to analyze a “natural experiment” occurring in California as residents transitioned to electric cars. 

The study analyzed data on total zero-emission vehicle (ZEV) registrations, air pollution levels, and asthma-related emergency room visits throughout California from 2013 to 2019. The researchers found that as ZEV adoption rates increased within a particular zip code, the corresponding levels of local air pollution and asthma-related emergency room visits in the areas also decreased.

Erika Garcia, PhD, MPH, an assistant professor of population and public health sciences at the Keck School of Medicine and the study’s lead author, noted that the study shows that changes made at the local level could already improve the health of a community. This is a notable victory for sustainable transportation and the fight against climate change

“When we think about the actions related to climate change, often it’s on a global level. But the idea that changes being made at the local level can improve the health of your own community could be a powerful message to the public and to policy makers,” Dr. Garcia said.

The study’s findings were outlined in an Abstract published in the journal Science of the Total Environment. A section of the Abstract can be viewed below. 

“We conducted a zip code-level ecologic study relating changes in annual number of ZEVs (nZEV) per 1000 population from 2013 to 2019 to: (i) annual average monitored nitrogen dioxide (NO2) concentrations and (ii) annual age-adjusted asthma-related emergency department (ED) visit rates, while considering educational attainment. 

“The average nZEV increased from 1.4 per 1000 population in 2013 (standard deviation [SD]: 2.1) to 14.7 per 1000 in 2019 (SD: 14.7). ZEV adoption was considerably slower in zip codes with lower educational attainment (p < 0.0001). A within-zip code increase of 20 ZEVs per 1000 was associated with a − 0.41 ppb change in annual average NO2 (95 % confidence interval [CI]:-1.12, 0.29) in an adjusted model. A within-zip code increase of 20 ZEVs per 1000 population was associated with a 3.2 % decrease in annual age-adjusted rate of asthma-related ED visits (95 % CI:-5.4, −0.9),” the researchers noted in the study’s Abstract. 

The study also showed that there is a significant “adoption gap” in low-resource zip codes when it comes to the adoption of zero-emission vehicles (ZEVs). The research team found that while the number of total ZEVs increased over time in California, the rate of adoption was much slower in low-resource areas. This disparity highlights an opportunity to address environmental justice in communities that are disproportionately impacted by pollution and its associated health issues.

SpaceX posts Starship booster feat that’s so nutty, it doesn’t even look real

The Super Heavy booster’s feat was so impressive that the whole maneuver almost looked like it was AI-generated.

SpaceX has shared a video of a remarkable feat achieved by Starship’s Super Heavy booster during its 11th flight test.

The Super Heavy booster’s feat was so impressive that the whole maneuver, which was captured on video, almost looked like it was AI-generated.

Super Heavy’s picture perfect hover

As could be seen in the video shared by SpaceX, Starship’s Super Heavy booster, which is nearly 400 feet tall, smoothly returned to Earth and hovered above the Gulf of America for a few seconds before it went for its soft water landing. The booster’s picture-perfect maneuver before splashing down all but capped a near-flawless mission for Starship, which is about to enter its V3 era with Flight 12.

The booster’s balance and stability were so perfect that some users on X joked that the whole thing looked AI-generated. Considering the size of Super Heavy, as well as the fact that the booster was returning from space, the hovering display all but showed that SpaceX is dead serious about keeping its dominant lead in the spaceflight sector.

Starship V2’s curtain call

As noted in a Space.com report, Flight Test 11 achieved every major goal SpaceX had set for the mission, including deploying Starlink mass simulators, relighting Raptor engines in space, and executing a stable reentry for both the Starship Upper Stage and the Super Heavy booster. The feat also marked the second time a Super Heavy booster has been reflown, a milestone in SpaceX’s quest to make the entire Starship system fully reusable.

Starship’s V2 vehicle will now give way to the upgraded Starship V3, which is designed for faster turnaround and higher payload capacity. The Starship program is expected to pursue even more aggressive targets in the coming months as well, with Elon Musk stating on social media platform X that SpaceX will attempt a tower catch for Starship Upper Stage as early as spring 2026.

After moving Tesla to Texas, Elon Musk is back in the Bay Area with Neuralink expansion

The news marks a noticeable step in Musk’s expanding presence in the Bay Area, despite the move of his biggest companies, Tesla and SpaceX, to Texas.

Recent reports have indicated that Elon Musk’s brain-implant startup, Neuralink, has leased a five-story, 144,000-square-foot building in South San Francisco. At the same time, Musk’s artificial intelligence startup xAI is reportedly also looking around for a Bay Area office. 

The news marks a noticeable step in Musk’s expanding presence in the Bay Area, despite the move of his biggest companies, Tesla and SpaceX, to Texas.

Neuralink’s Bay Area expansion

As noted in a report from the San Francisco Business Times, the property that Neuralink has leased is located at 499 Forbes Boulevard, and it was built by Aralon Properties before it was leased to cancer test developer InterVenn Biosciences. The site, however, had remained vacant since 2023 after InterVenn canceled its 10-year lease.

xAI, Musk’s artificial intelligence startup, is reportedly scouting for an even larger Bay Area office as well, as noted in a report from the San Francisco Chronicle. Combined, the two ventures could secure nearly 400,000 square feet of local workspace, a move seen as a symbolic return of sorts for Musk-led innovation to Silicon Valley.

Neuralink’s momentum

Founded in 2016, Neuralink develops brain-computer interfaces intended to help paralyzed patients control digital devices through thought. The company received U.S. regulatory approval in 2023 to begin human trials, with its first patient, quadriplegic Noland Arbaugh, making headlines for his stunning ability to control a computer cursor and play games using only his mind. Since receiving his implant, Arbaugh has stated that he now browses the web, plays video games like Mario Kart, studies neuroscience, and operates his smart home without lifting a finger.

Nauralink is only just getting started, with Elon Musk noting on X that the company is busy preparing its next product, Blindsight, for human trials. As per Musk, Neuralink is “aiming to restore (limited) sight to the completely blind next year,” an aggressive target for a potentially life-changing device.

Tesla seems to be ramping the tests of its autonomous two-seater, the Cybercab, once more. This was hinted at in recent drone footage from both the Fremont Factory and Gigafactory Texas.

The fresh sightings of the Cybercab in the Fremont Factory and Giga Texas have renewed conversations about the vehicle potentially being built with manual controls today. 

Fresh Cybercab tests

As noted by longtime drone operator Joe Tegtmeyer on social media platform X, he recently spotted a Cybercab driving on Giga Texas’ South River Road to the West side. Interestingly enough, the longtime Giga Texas watcher noted that this was the first Cybercab that he had seen conducting road tests in a while.

Over in the Fremont Factory, another Cybercab was spotted driving around the facility’s testing area. Similar to the Cybercab in the Giga Texas sighting, the vehicle that was spotted in the Fremont Factory seemed to be manually driven, at least based on the way it was being steered. This behavior has incited speculations among Tesla watchers that current Cybercab test units have manual controls, unlike their production version, which would have no steering wheel or pedals. 

Cybercab production preparation

The sightings of Cybercabs around the Fremont Factory and Giga Texas bode well for the vehicle’s development and impending production. It does, if any, complement reports that Tesla has been busy setting up production equipment for Giga Texas’ Cybercab production line. At the same time, drone footage around the Giga Texas complex has also revealed that Tesla is stockpiling some Cybercab castings, a likely sign that initial test production of the vehicle might soon begin.

The Cybercab is expected to be Tesla’s highest volume vehicle, with CEO Elon Musk stating that he expects the company to achieve a run rate of 2 million Cybercabs annually. He also mentioned that the Cybercab will be easy to produce thanks to its Unboxed manufacturing process, so much so that its production would resemble a high-speed consumer electronics line instead of an automotive assembly line.
