Scientists create ‘living concrete’ that could one day be used on Mars
Builders have been making concrete the same way for hundreds of years: by mixing sand with various binding materials.
However, a team of researchers at the University of Colorado, Boulder has a different approach. They’re making a new kind of concrete, one that is alive and can even replicate itself.
It’s made using a common type of microbe: cyanobacteria. This type of organism gets its energy through photosynthesis.
The field of synthetic biology is booming with researchers exploring new ways to build and new materials to work with. Recently, a different team has proposed the use of mycelium as another type of building material.
A major advantage of this new type of concrete is that it can heal itself, repairing any cracks that may appear.
The new concrete type was recently detailed in the journal Matter. “We already use biological materials in our buildings, like wood, but those materials are no longer alive,” Wil Srubar, an assistant professor in the Department of Civil, Environmental and Architectural Engineering (CEAE) said in a news statement. “We’re asking: Why can’t we keep them alive and have that biology do something beneficial, too?”
So how did the group build this new type of living concrete? First, the researchers tried putting the cyanobacteria in a mixture containing warm water, sand, and other nutrients. The microbes began producing calcium carbonate and gradually cemented the sand particles together.
But the process was extremely slow — too slow in fact for the project’s funder, Darpa, the Department of Defense’s research offshoot.
The team switched its focus to gelatin, a food ingredient that once dissolved in water and cooled, created special bonds between its molecules. The team decided to try adding gelatin to the bacteria mixture.
Success! The gelatin not only provided more structure, but also worked with the bacteria and the result was faster-growing, living concrete. It took about a day for the bacteria to form concrete blocks, and although it was weaker than conventional concrete, it was sturdy enough for a person to stand on.
Blocks ranged in size from two-inch cubes to shoebox-sized to larger truss pieces. When stored in relatively dry air and at room temperature, it takes a few days for the blocks to reach their maximum strength. The bacteria can survive for several weeks and even be rejuvenated – resulting in further growth. Under the right conditions, of course.
“We know that bacteria grow at an exponential rate,” Srubar said. “That’s different than how we, say, 3D-print a block or cast a brick. If we can grow our materials biologically, then we can manufacture at an exponential scale.”
DARPA is extremely interested in this research and in self-growing material in general. That’s because it can be used to build structures in remote and inhospitable areas such as the desert or even outer space.
If the living concrete can prove to be scalable, that would reduce the number of materials that we will need to launch, which is a huge deal when even pound counts.
It’s much easier to bring biology with us than to carry bulky building materials to space. Perhaps the first humans on Mars will live in habitats fashioned out of cyanobacteria concrete bricks, or even mushrooms.
“Nature has figured out how to do a lot of things in a clever and efficient way,” Srubar said. “In austere environments, these materials would perform especially well because they use light from the sun to grow and proliferate with very little exogenous material needed for their growth,” added Srubar. “It’s going to happen one way or another, and we’re not going to be trucking bags of cement all the way to Mars. I really do think that we’ll be bringing biology with us once we go.”

Tesla is making two big upgrades to the Model 3, coding shows
According to coding found in the European and Chinese configurators, Tesla is planning to make two big upgrades: Black Headliner offerings and a new 16-inch QHD display, similar to that on the Model Y Performance.
Tesla is making two big upgrades to the Model 3, one of which is widely requested by owners and fans, and another that it has already started to make on some trim levels of other models within the lineup.
The changes appear to be taking effect in the European and Chinese markets, but these are expected to come to the United States based on what Tesla has done with the Model Y.
According to coding found in the European and Chinese configurators, Tesla is planning to make two big upgrades: Black Headliner offerings and a new 16-inch QHD display, similar to that on the Model Y Performance.
These changes in the coding were spotted by X user BERKANT, who shared the findings on the social media platform this morning:
🚨 Model 3 changes spotted in Tesla backend
• New interior code: IN3PB (Interior 3 Premium Black)
• Linked to Alcantara-style black headliner
• Mapped to 2026 Model 3 Performance and Premium VINs• EPC now shows: “Display_16_QHD”
• Multiple 2026 builds marked with… pic.twitter.com/OkDM5EdbTu— BERKANT (@Tesla_NL_TR) February 23, 2026
It appears these new upgrades will roll out with the Model 3 Performance and Tesla’s Premium trim levels of the all-electric sedan.
The changes are welcome. Tesla fans have been requesting that its Model 3 and Model Y offerings receive a black headliner, as even with the black interior options, the headliner is grey.
Tesla recently upgraded Model Y vehicles to this black headliner option, even in the United States, so it seems as if the Model 3 will get the same treatment as it appears to be getting in the Eastern hemisphere.
Tesla has been basically accentuating the Model 3 and Model Y with small upgrades that owners have been wanting, and it has been a focal point of the company’s future plans as it phases out other vehicles like the Model S and Model X.
Additionally, Tesla offered an excellent 0.99% APR last week on the Model 3, hoping to push more units out the door to support a strong Q1 delivery figure at the beginning of April.

SpaceX secures FAA approval for 44 annual Starship launches in Florida
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings.
SpaceX has received environmental approval from the Federal Aviation Administration (FAA) to conduct up to 44 Starship-Super Heavy launches per year from Kennedy Space Center Launch Complex 39A in Florida.
The decision allows the company to proceed with plans tied to its next-generation launch system and future satellite deployments.
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings. The approval concludes the agency’s public comment period and outlines required mitigation measures related to noise, emissions, wildlife, and airspace management.
Construction of Starship infrastructure at Launch Complex 39A is nearing completion. The site, previously used for Apollo and space shuttle missions, is transitioning to support Starship operations, as noted in a Florida Today report.
If fully deployed across Kennedy Space Center and nearby Cape Canaveral Space Force Station, Starship activity on the Space Coast could exceed 120 launches annually, excluding tests. Separately, the U.S. Air Force has authorized repurposing Space Launch Complex 37 for potential additional Starship activity, pending further FAA airspace analysis.
The approval supports SpaceX’s long-term strategy, which includes deploying a large constellation of satellites intended to power space-based artificial intelligence data infrastructure. The company has previously indicated that expanded Starship capacity will be central to that effort.
The FAA review identified likely impacts from increased noise, nitrogen oxide emissions, and temporary airspace closures. Commercial flights may experience periodic delays during launch windows. The agency, however, determined these effects would be intermittent and manageable through scheduling, public notification, and worker safety protocols.
Wildlife protections are required under the approval, Florida Today noted. These include lighting controls to protect sea turtles, seasonal monitoring of scrub jays and beach mice, and restrictions on offshore landings to avoid coral reefs and right whale critical habitat. Recovery vessels must also carry trained observers to prevent collisions with protected marine species.

Texas township wants The Boring Company to build it a Loop system
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge.”
The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes.
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.
The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.
Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.
“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.
“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.
The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.
Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.
“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement.
“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”
