US military uses genetic engineering to develop “living tripwires” for submarines
The US Department of Defense (DoD) is investing $45 million dollars in a tri-service effort that focuses on synthetic biology (SynBio) for use in military technologies. This interdisciplinary scientific field primarily involves altering the genetic makeup of organisms to achieve specific behavior, and the military wants in on its potential applications. By uniting SynBio experts within the US Air Force, Army, and Navy, DoD officials hope to develop serious capabilities for use throughout the military’s branches.
The long form name of this project is the Applied Research for the Advancement of Science and Technology Priorities Program on Synthetic Biology for Military Environments, and the mission is obvious from its title alone. While still in the early research stages, engineering organisms could provide numerous tools with direct defense applications.
For example, organisms engineered to change their colors based on their environment could be used as living camouflage, and medications infused with protective microbes could help service member survival in tough conditions. However, it’s perhaps the US Naval Research Laboratory (NRL) in Washington DC that may hold the relevant interest in developing SynBio capabilities due to the marine environment potentials it holds.
Above the water, engineered self-repairing organisms could spell out self-healing paint for ships and aircraft carriers, cutting billions from the US Navy’s fleet maintenance costs. Even more important for defense needs, though, are the modified organisms that could help the branch’s deep water operations, i.e., submarines. By modifying the environmental response of naturally present organisms, naval defense could have a new type of radar at their disposal.
An abundant seawater-native bacteria with “clinging” properties called Marinobacter is a prime candidate for the DoD’s purposes. Specifically, the organism could be genetically engineered to react to certain types of molecules that aren’t naturally occurring in the ocean, such as diesel fuel or human DNA, and then spread into targeted environments for monitoring. This reaction could perhaps be the release of an electron, thus creating an electrical signal which nearby drones could pick up and transmit where necessary. The ability to detect non-friendly submarines is the key capability the researchers are aiming to achieve, the bacteria acting as “living tripwires.”
The field of synthetic biology is not new in the civilian world. In fact, consumer products currently exist based on it, such as bio fuels, soaps, cleaners, food additives, and a variety of industrial and manufacturing products. One of the challenges of bringing this type of technology to the field for military use is making the modified organisms tough enough to endure the environments needed.
“If you want to move a biological bio-based sensor to the field you try to ruggedize those organisms. You try to protect them…[and]…increase their longevity in these harsh environments,” explained Dimitra Stratis-Cullum, the lead of U.S. Army Research Laboratory biomaterials team, in a recent forum hosted by the Johns Hopkins University Applied Physics Laboratory.
The current genetic research being conducted in SynBio has demonstrated that the genes of E. coli bacteria can be manipulated to express properties relevant to the larger goal of underwater sensing. However, the significant differences between the E. Coli and the types of organisms natural to deep water environments, such as Marinobacter, can be compared to the differences between mice and humans.
The initial point really is to either prove that the desired outcome is possible or collect data to assist in that effort. In other words, there’s still a lot of work to be done, but making the effort a priority, such as what the Navy’s done with its “Task Force Ocean” mission aimed at strengthening partnerships within academia and the private sector regarding Navy-relevant ocean science, is a focused step in the right direction for the military to achieve its goals in SynBio.

Tesla Model X shocks everyone by crushing every other used car in America
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
The Tesla Model X was the fastest-selling used vehicle in the United States in the first quarter of the year, crushing every other used car in America.
iSeeCars data for the first quarter shows that the Model X was the fastest-selling used car, lasting just 25.6 days on the market on average, two days better than that of the second-place Lexus RX 350h. The Cybertruck, Model Y, and Model S, in seventh, ninth, and thirteenth place, respectively, also made the list.
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Bringing closure to these two vehicles signaled the end of the road for the cars that have effectively built Tesla’s reputation for luxury and high-end passenger vehicles.
Relying on the sales of its mass market Model Y and Model 3, as well as leaning on the success of future products like the Cybercab, is the angle Tesla has chosen to take.
Teslas are also performing extremely well as a whole on the resale market. iSeeCars data shows that, “while the average price of a 1- to 5-year-old non-Tesla EV fell 10.3% in Q1 2026 year-over-year, the average price of a used Tesla was essentially flat at 0.1% lower across the same period. Traditional gas car prices dropped 2.8% during this same period.”
Additionally, market share for gas cars has dropped nearly 3 percent since the same quarter last year. Tesla has remained level, while the non-Tesla EV market share has increased 30 percent, mostly due to more models available.
Nevertheless, those non-Tesla EVs have seen their value drop by over 10 percent, while Tesla’s values have remained level.
Executive Analyst Karl Brauer said:
“Used electric vehicles without a Tesla badge have lost more than 10% of their value in the past year. This compares to stable values for Teslas and hybrids, and a modest 2.8% drop for traditional gasoline vehicles.”
Teslas, as well as non-luxury hybrids, are displaying the strongest resistance in the face of faltering demand, the publication says. But the more impressive performance is that of the Model X alone.
Tesla’s decision to stop production of the Model X may have played some part in the vehicle’s pristine performance in Q1. With the car already placed at a premium price point, used models are already more appealing to consumers. Perhaps second-hand versions were more than enough for those who wanted a Model X, and only a Model X.

Tesla Cybertruck’s head-scratching trim sold terribly, recall documents reveal
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
After Tesla decided to build a Rear-Wheel-Drive Cybertruck trim back in 2025, which was void of many features and only featured a small discount.
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
The recall deals with a potentially separating wheel stud and potentially impacts 173 Cybertruck units with the 18-inch steel wheels. The Cybertruck RWD was the only trim level to feature these, and the 173 potentially impacted units represent a portion of the population of pickups. Therefore, it’s not the entire number of RWD Cybertruck sold, but it could show how little interest it gathered.
The NHTSA document states:
“On affected vehicles, higher severity road perturbations and cornering may strain the stud hole in the wheel rotor, causing cracks to form. If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”
Only 5 percent are expected to be impacted, meaning less than 10 units will have the issue if the NHTSA and Tesla estimates are correct. Nevertheless, the true story here is how terribly the RWD Cybertruck sold.
Tesla ended production and stopped offering the RWD Cybertruck to customers last September. For just $10,000 less than the All-Wheel-Drive trim, Tesla offered the RWD Cybertruck with just one motor, textile seats instead of leather, only 7 speakers instead of 15, no Rear Touchscreen, no Powered Tonneau Cover for the truck bed, and no 120v/240v outlets.
For just $10,000 more, at $79,990, owners could have received all of those premium features, as well as a more capable All-Wheel-Drive powertrain that featured Adaptive Air Suspension. The discount simply was not worth the sacrifices.
Orders were few and far between, and sources told us that when it was offered, sales were extremely tempered because customers could not see the value in this trim level.
Even Tesla’s most loyal supporters thought the offering was kind of a joke, and the $10,000 extra was simply worth it.

Tesla Semi sends clear message to Diesel rivals with latest move
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
Tesla has officially launched Semi production at what will be a mind-boggling rate of approximately 50,000 units per year.
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
The company finally announced on April 29 that the first Tesla Semi truck has rolled off its new high-volume production line at the factory. This marks the transition from limited pilot builds to scaled manufacturing for the Class 8 all-electric heavy-duty truck, nearly nine years after its dramatic 2017 unveiling.

Tesla initially promised high-volume deliveries by 2019–2020, but battery supply constraints and prioritization for passenger vehicles delayed progress. The new 1.7-million-square-foot factory, purpose-built next to Gigafactory Nevada’s 4680 cell production lines, resolves those bottlenecks through deep vertical integration.
The Semi uses Tesla’s structural battery packs with cylindrical 4680 cells manufactured on-site. This integration enables efficient supply, reduced logistics costs, and the potential for high output. The factory is designed for an eventual annual capacity of approximately 50,000 trucks, positioning Tesla to address growing demand in long-haul freight electrification.
Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
Operating economics favor the Semi through dramatically lower fuel and maintenance costs compared to traditional diesel rigs, and companies involved in a pilot program for the Semi with Tesla have shown that.
Electricity is far cheaper than diesel on a per-mile basis, while the electric powertrain features fewer moving parts, reducing service intervals and lifetime expenses. Early deployments with customers like PepsiCo and others have validated these advantages in real-world service.
The Nevada factory’s ramp-up is targeted for full volume output before the end of June 2026, aligning with broader Tesla production goals for 2026. This includes parallel efforts on other new vehicles while expanding the Megacharger infrastructure to support widespread adoption.
By localizing battery and truck production, Tesla gains advantages in cost, quality control, and scalability that many competitors sourcing cells externally lack. The start of high-volume Semi production represents a pivotal step in Tesla’s strategy to electrify heavy transportation, potentially accelerating the shift toward zero-emission freight across North America and beyond.
As output increases, the Semi could reshape long-haul logistics with its combination of performance, efficiency, and sustainability.
