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’s AI lead Ashok Elluswamy doubled down on the company’s strategy regarding Full Self-Driving’s speed settings, and owners are definitely confused.
Earlier versions of Full Self-Driving allowed owners to set a max speed that the vehicle could travel while operating under the semi-autonomous driver assistance platform. This allowed more customization for the driver, giving them the ability to experience FSD’s robust performance with their own personal preferences.
Speed is massively important for obvious reasons — it’s not only a question of keeping the vehicle occupants comfortable by traveling at a safe speed, but it’s also something that could contribute to a ticket or infraction from law enforcement.
With the release of FSD v14 last year, Tesla removed the ability to set a max speed and instead opted for five Speed Profiles, ranging from “Sloth,” the most conservative, to “Mad Max,” the most aggressive and spirited. These profiles not only control speed, but also how frequently the vehicle will execute passes, perform lane changes, and other contributing factors.
The removal of the Max Speed setting was a major complaint amongst the Tesla community because it left owners scrambling for a way to experience suitable behaviors while traveling at an appropriate speed. Most felt the driving profiles would be a good indicator of the behaviors, while speed would still be left up to the discretion of the driver.
Instead, Tesla’s Speed Profiles determine both, and the constant tinkering of how they behave has been a major bottleneck and point of confusion for both owners and the company. From update to update, the Speed Profiles will change, sometimes more drastically than others. Some owners have complained that the “Standard” profile is too fast, while others have experienced “Mad Max” traveling below the speed limit:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

These things change with each update, but the big complaint is that owners are on the hook for any tickets that come from FSD’s infractions; that’s the caveat of the suite being named FSD (Supervised). It ultimately means the driver is responsible, and the automaker has no liability when it comes to speeding tickets or general traffic infractions.
It is the driver’s responsibility to take over or adjust based on this.
Elluswamy essentially confirmed that there are no plans to bring back Max Speed control, because it is what he referred to as “an anti pattern.” He then echoed something that CEO Elon Musk has started to really push with FSD, and that’s the idea that Tesla is really honing in on the preferences of the driver.
Max speed control is an anti pattern.
We are working on better learning of user’s implied preferences.

Owners were confused by Tesla’s decision, stating that there must be a better way, especially considering disengagements for incorrect speeds are common:
This…. is not the way

😭 I appreciate this mentality ! But currently the no.1 reason I disengage in Australia is incorrect speed zones.

This is fine but you need to start accepting liability for speeding tickets then. https://t.co/lyCgdA83gQ

From personal experience and using FSD for over 72 percent of my driving miles since v14 was released late last year, I make Speed Profile adjustments constantly. If FSD is traveling a tad too quickly, I will scale it back, and if it’s too conservative, I’ll make it more aggressive.
I don’t complain about making the Speed Profile changes too frequently, but it would certainly be nice to have it happen less frequently. There are far too many times I am concerned about getting a ticket, even in Standard mode.
The biggest issue for me, personally, which seems to be echoed throughout the community, is the fact that Tesla’s goal is to minimize disengagements. Many drivers are stating that speed is a major reason for disengagements.
However, Tesla is not willing to bring back this one level of input because it would technically be a regression.

Whether it’s right or wrong in your opinion, it is what Tesla is going with, and it seems like it has pivoted quite a bit from its other strategies for minimizing interventions by pushing its AI to behave in a way that would fit the occupant’s personal preferences.
Tesla is one of several automakers whose vehicles qualify for an awesome new first-time EV buyer incentive program in California.
The Golden State launched the MyFirstEV incentive program, which helps those buying an electric vehicle for the first time with a $3,500 incentive on new-inventory purchases of a Model 3 or Model Y.
First-time electric vehicle buyers in California can now get $3,500 off eligible Model 3 and Model Y new inventory vehicle purchases.
To be eligible, you must place your order on or after August 3, 2026 and take delivery while funds are still available. The incentive applies to… pic.twitter.com/yuXF00XA50

The incentive requires an order on or after August 3, and delivery must be taken while the program is still being funded. California has set aside $135.5 million to help strengthen its SEV market and support automotive innovation.
Incentives are offered at the point of sale, and used EVs are also available for a partial incentive of $1,750. Half of the $3,500 and $1,750 incentive amounts are covered by California, with the other half being covered by participating OEMs.
-
Additionally, rules apply for MSRP and how the vehicle will qualify for the incentive. Any vehicle from a non-California headquartered OEM must have an MSRP of $50,000 or less. Used vehicles must be priced at $25,000 or less and must be at least two model years older than the year of purchase.
The cars must also be purchased from manufacturers as certified pre-owned vehicles. Private dealerships are not eligible.
In total, California expects to incentivize over 73,000 ZEVs.

Elon Musk’s space exploration company, SpaceX (NASDAQ: SPCX), is set to report its earnings for the second quarter today in what will be its first-ever earnings call since going public in July.
SpaceX is trading down roughly 25 percent from its IPO. These early stock signals are usually a bit tumultuous, and considering this is the first company actively launching rockets that is available on the stock exchange, investors might have a tendency to be a bit skittish.
However, there are going to be some details that investors will hear for the first time today on the earnings call. Here’s what to look for:
Wall Street Expectations
Revenue is expected to fall somewhere around $6.8 billion, and will be heavily driven by Starlink, which is SpaceX’s widely popular satellite internet platform that has been adopted by numerous airlines, cruise ships, and other maritime operations. It is also available for consumers at home or in their cars.
Earnings Per Share (EPS) expectations fall at a net loss of $0.23 per share. Wall Street sees this as a total net loss of roughly $1.9 billion.
EBITDA is expected to come in between $2 billion and $2.1 billion.
What Investors Want to Know
Tesla uses the Say platform to help work with both retail and institutional investors to answer relevant and quality questions that address concerns or questions that they might have.
-
However, SpaceX is doing things differently, as the company launched its own Investor Relations website where these questions are being fielded. Just like the Tesla questions, they seem to be less focused on the operational tasks and overall progress of the company, and more novelty.
Here are the top five:
- Has the team thought about what possibilities there are with your mascot Asteroid? Whether it’s starting additional foundations for kids in its name, helping kids learn about space, etc. Kids are our future, and Asteroid would be a fun and easy way to help.
- Baby Asteroid is already making a difference through charity around the world. Could SpaceX take it even further with programs that inspire kids to explore space?
- SpaceX has some legendary vehicle names. Would you ever allow the public to name a Starship, even knowing there is a 99% chance it becomes Shipy McShipface?
- When can we expect to see more footage of the Human Landing System?
- Will Asteroid (your mascot) go to Mars?
SpaceX will report its earnings today, August 4, at 4:30 P.M. EDT.
