“Smart skin” can identify weaknesses in bridges and airplanes using laser scanner
Recent research results have demonstrated that two-dimensional, on-demand mapping of the accumulated strain on metal structures will soon be a reality thanks to an engineered “smart skin” that’s only a fraction of the width of a human hair. By utilizing the unique properties of single-walled carbon nanotubes, a two-layer film airbrushed onto surfaces of bridges, pipelines, and airplanes, among others, can be scanned to reveal weaknesses in near real-time. As a bonus, the technology is barely visible even on a transparent surface, making it that much more flexible as an application.
Stress-inducing events, along with regular wear and tear, can deform structures and machines, affecting their safety and operability. Mechanical strain on structural surfaces provides information on the condition of the materials such as damage location and severity. Existing conventional sensors are only able to measure strain in one point along one axis, but with the smart skin technology, strain detection in any direction or location will be possible.
How “Smart Skin” Technology is Used
In 2002, researchers discovered that single-wall carbon nanotubes fluoresce, i.e., glow brightly when stimulated by a light source. Later, the fluorescence was further found to change color when stretched. This optical property was then considered in the context of metal structures that are subject to strain, specifically to apply the property as a diagnostic tool. To obtain the fluorescent data, researchers applied the smart skin to a testing surface, irradiated the area with a small laser scanner, and captured the resulting nanotube color emissions with an infrared spectrometer. Finally, two-dimensional maps of the accumulated strain were generated with the results.

The primary researchers, Professors Satish Nagarajaiah and Bruce Weisman of Rice University in Texas, have published two scientific papers explaining the methods used for achieving this technology and the results of its proof-of-principle application. As described in the papers, aluminum bars with holes or notches in areas of potential stress were tested with the laser technique to demonstrate the full potential of their invention. The points measured were located 1 millimeter apart, but the researchers stated that the points could be located 20 times closer for even more accurate readings. Standard strain sensors have points located several millimeters apart.
What Are Carbon Nanotubes?
Carbon nanotubes (CNTs) are carbon molecules that have been structurally modified into cylinders, or rather, rolled up sheets of carbon atoms. There has been some evidence suggesting that CNTs can be formed via natural processes such as volcanic events. However, to really capitalize on their unique characteristics, production in a laboratory environment is much more efficient.
Several methods can be used for production, but the most widely used method for synthesizing CNTs is chemical vapor deposition (CVD). This process combines a catalyzing metal with a carbon-containing gas which are heated to approximately 1400 degrees Fahrenheit, triggering the carbon molecules to assemble and grow into nanotubes. The resulting formation resembles a forest or lawn grass, each trunk or blade averaging .43 nanometers in diameter. The length is dependent on variables such as the amount of time spent in the high heat environment.

Besides surface analysis, carbon nanotubes have proven invaluable in many research and commercial arenas, their luminescence being only one of many properties that can improve and enable other technologies. Their mechanical tensile strength is 400 times that of steel while only having one sixth the density, making them very lightweight. CNTs also have highly conductive electrical and thermal properties, are extremely resistant to corrosion, and can be filled with other nanomaterials. All of these advantages open up their applications to include solar cells, sensors, drug delivery, electronic devices and shielding, lithium-ion batteries, body armor, and perhaps even a space elevator, assuming significant advances overcome its hurdles.
Next Steps
The nanotube-laced smart skin is ready for scaling up into real-world applications, but its chosen industry may take time to adopt given the general resistance to change in a field with long-standing existing technology. While awaiting embrace in the arena it was primarily designed for, the smart skin has other potential uses in engineering research applications. Bruce Weisman, also the discoverer of CNT fluorescence, anticipates its advantages being used for testing the design of small-scaled structures and engines prior to deployment. Niche applications like these may be the primary entry point into the market for some time to come. In the meantime, the researchers plan to continue developing their strain reader to capture simultaneous readings from large surfaces.

The Model Y L stands out with its stretched dimensions: 4,976 mm long and a 3,040 mm wheelbase—179 mm and 150 mm longer, respectively, than the standard Model Y. Height increases slightly to 1,668 mm, creating a true three-row, 2+2+2 layout with individual captain’s chairs in the second row for easier third-row access.
Maximum cargo capacity reaches 2,539 liters with seats folded, making it ideal for growing families or those needing versatile space in dense urban environments. But it’s not just a grocery-getter or a kid-hauler: The performance matches Tesla’s reputation.
Dual-motor all-wheel drive delivers 0-100 km/h acceleration in about 5.0 seconds (or 4.5 seconds in some market specs), with a top speed of 201 km/h. The vehicle boasts a WLTP-rated range of up to 681 km, supported by an approximately 88-97 kWh battery pack (market-dependent) and 250 kW DC fast charging.
With deliveries slated for Q2 2026 and strong early interest mirroring China’s rapid pre-orders, the Model Y L could become a bestseller in these dynamic markets. Tesla’s targeted expansion essentially generalizes its commitment to tailoring vehicles to regional needs while advancing sustainable mobility across Asia.

Tesla hit by Iranian missile debris in Israel
A Tesla in Israel absorbed a direct hit from missile debris, and the glassroof held.
On March 30, 2026, Lara Shusterman was in Netanya, Israel when Iranian ballistic missiles triggered air raid sirens across the city. While she remained in safety, her 2024 Tesla Model Y did not escape untouched. A heavy piece of missile debris struck the car’s massive glass roof, leaving a deep crater but without shattering. In a Facebook post to the Tesla Israel community the following morning, Shusterman described what happened: “The glass did not shatter into dangerous shards. She stopped the damage and pushed the metal part to the ground.” She closed by thanking Elon Musk and the Tesla team for building what she called “security and a sense of trust even in extreme situations.”
Netanya is a coastal city in central Israel, roughly 18 miles north of Tel Aviv and has been among the areas most frequently struck during Iran’s ongoing missile campaign, following coordinated U.S. and Israeli strikes on Iranian military infrastructure. Falling shrapnel from intercepted missiles is a common occurrence.

The incident is a testament to Tesla’s structural engineering. Tesla’s glass roof is designed to support over four times the vehicle’s own weight. That strength has shown up in real-world accidents too. In 2021, a Model Y in California was struck by a falling tree during a storm, with the glass roof holding firm and the cabin remaining intact. In another widely reported incident, a Tesla Model Y plunged 250 feet off the cliff at Devil’s Slide in California in January 2023, with all four occupants, including two young children, surviving.
Disturbing details about Tesla’s 250-foot cliff drop emerge amid initial investigation
Tesla officially launched sales in Israel in early 2021 and captured over 60 percent of Israel’s EV market in the first year. The brand’s foothold in Israel remains significant. Tens of thousands of Teslas are now on Israeli roads, making incidents like Shusterman’s easy to corroborate. On the same week her Model Y took the hit, the U.S. Space Force awarded SpaceX a $178.5 million contract to launch missile tracking satellites, a separate but fitting reminder of how intertwined the Musk ecosystem has become with the realities of modern conflict.

Elon Musk calls out $2 trillion SpaceX IPO valuation as ‘BS’
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
Elon Musk is quick to call out any false information regarding him or his companies on his social media platform, known as X.
A recent report that claimed SpaceX was aiming to go public with an IPO in the coming weeks at a massive valuation of $2 trillion was called out by Musk, who referred to it as “BS.”
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
The exchange highlights ongoing media speculation about the rocket company’s future and Musk’s frustration with what he views as inaccurate financial reporting. The report came from Bloomberg.
Don’t believe everything you read.
Bloomberg publishes bs.
— Elon Musk (@elonmusk) April 3, 2026
The controversy erupted on April 2, 2026, when influencer Mario Nawfal amplified claims from Bloomberg.
The outlet posted that SpaceX had boosted its IPO target valuation above $2 trillion, describing it as potentially one of the largest public offerings in history. Musk challenged the story.
It echoes past instances where Musk has corrected valuation rumors about his companies, emphasizing that speculation often outpaces reality.
Background context adds nuance.
Earlier reports indicated SpaceX had filed confidential IPO paperwork with the U.S. Securities and Exchange Commission, potentially positioning it for a record-breaking debut that could eclipse Saudi Aramco’s 2019 listing.
Initial estimates pegged a possible valuation north of $1.75 trillion, building on a post-merger figure around $1.25 trillion after SpaceX absorbed xAI. A subsequent Bloomberg update claimed advisers were floating figures above $2 trillion to investors, with the offering potentially raising up to $75 billion.
SpaceX remains a private powerhouse. Its achievements include thousands of Starlink satellites providing global broadband, routine Falcon 9 rocket reusability, and a mission to slash launch costs, along with ambitions for Starship to enable Mars colonization.
The company also benefits from government contracts with NASA and the Department of Defense. A public listing could democratize access for retail investors while subjecting SpaceX to greater scrutiny and quarterly reporting pressures.
Critics of the reports point to the confidential nature of filings, which limits verifiable details. Musk has previously downplayed inflated valuations, once calling an $800 billion figure for SpaceX “too high.”
Supporters argue that hype around mega-IPOs, especially amid the ongoing AI fervor, fuels premature narratives that distract from core technical milestones, such as full Starship reusability and Starlink constellation expansion.
The incident reflects broader tensions in tech finance. Anonymous sourcing in valuation stories can drive market chatter and betting activity, yet it risks misinformation.
Bloomberg defended its reporting through multiple articles citing “people familiar with the matter,” but Musk’s blunt dismissal resonated widely on X, with users piling on to question media reliability.
Whether SpaceX ultimately goes public remains uncertain. Musk has teased an IPO tied to Starlink maturity, but priorities center on engineering breakthroughs over Wall Street timelines. For now, the $2 trillion figure joins a list of rumored milestones that Musk insists should be taken with skepticism.
