Remote Yucatán Jungle Uncovers a Row of Unlooted Maya Monuments

Archaeologists in Mexico’s Yucatán Peninsula discovered 14 Maya monuments at the remote site of Minanbé, including a well-preserved 40‑foot temple and inscriptions dating to AD 849 and the late 600s. The untouched condition suggests little looting, highlighting the site's political importance as a regional town rather than a major city. Access required extensive jungle treks after ATV travel, with lidar helping to locate the site. Further excavations are planned to learn more about regional urbanization and the late‑classic Maya collapse; funding came from Slovenian agencies and private donors.

Heaven Sword of the Da’an River: Taiwan’s 84.1-meter giant crowned East Asia’s tallest tree

Researchers in Taiwan identified the Heaven Sword of the Da’an River as East Asia’s tallest known tree, a 84.1-meter (276-foot) Taiwania fir about 1,000 years old, confirmed after a decade of aerial lidar surveys, map-based targeting, and final tape-drop measurements from the tree itself; the discovery highlights giant trees’ role in carbon storage and biodiversity and demonstrates how combining remote sensing with on-site verification can uncover Earth’s rare giants.

Lidar-Equipped, Budget-Friendly: Mammotion Luba 3 AWD 5000H Brings Auto Mowing to the Lawn

An in-depth hands-on with Mammotion’s Luba 3 AWD 5000H, which adds lidar and NetRTK to the affordable lawn-robot line, removing the need for a dedicated RTK base station by using cellular/Wi‑Fi corrections; it keeps the app-driven setup, stores maps on the mower itself, and pairs a larger 5000H battery with ongoing improvements for easier, set‑and‑forget mowing—though it’s pricier than the Luba 2 and still requires careful mapping for tricky yards.

LiDAR lasers trace space junk's footprint in the upper atmosphere

Scientists are using ground-based LiDAR to detect ablation from reentering space debris in the upper atmosphere. A lithium cloud linked to SpaceX’s Falcon 9 upper-stage reentry was observed, and Leibniz Institute researchers are testing a three-channel multi-species LiDAR to detect metals and propellant residues (e.g., copper, aluminum oxide, hydrogen fluoride). The findings suggest debris reentry is altering the mesosphere and upper stratosphere, with potential implications for the ozone layer as satellite megaconstellations grow; experts call for expanded monitoring and dedicated efforts to track space waste reentry.

Three Undervalued AI Infrastructure Plays Set for Breakout

An InvestorPlace Smart Money piece highlights Fluence Energy (FLNC), Atkore (ATKR), and Hesai Group (HSAI) as undervalued AI infrastructure plays poised to benefit from surging AI data-center demand. Fluence is expanding grid-scale energy storage, Atkore provides essential cabling and power systems, and Hesai dominates lidar for autonomous tech. All three have traded sideways despite rising AI demand, suggesting potential upside as the AI boom accelerates.

China’s AI-EV Surge Takes Center Stage at Beijing Auto Show 2026

Beijing Auto Show 2026 set a record for size and premieres, signaling a shift in which China leads electrification and AI-enabled driving across price tiers. The show showcased high-tech features like lidar, drive-by-wire, and AI chips across affordable and flagship models—from XPeng’s Level 4-focused GX and Li Auto’s L9 Livis, to Geely’s robotaxi EVA Cab and a wave of affordable lidar-equipped EVs. Global automakers partner with Chinese suppliers (Huawei, ByteDance, Momenta, Qualcomm), VW rolls out a range-extended ID. Era 9X, and even a flying-car “land carrier” by Aridge. With Xiaomi’s Vision Gran Turismo concept and other bold concepts, the event underscores China’s rising dominance in EV tech, AI, and new mobility formats rather than a cheap-versus-premium divide.

Arizona's Mummy Cave: 1,700-year-old cliff village archived in 3D for preservation

Laser scanning has captured a 1,700-year-old cliff-dwelling in Tse Yaa Kin (Mummy Cave), Arizona, detailing more than 165 rooms in a precise 3D archive. Researchers using LiDAR have created a digital twin to test stabilization options while preserving plaster and tool marks, as erosion threatens the fragile mud walls. Indigenous communities’ consent guides access and sharing to protect the site, and the project also trains students and plans to continue through 2027 to safeguard the record for future study.

First real-time lidar capture of space debris pollution from a rocket re-entry

First real-time lidar capture of space debris pollution from a rocket re-entry

Scientists used a ground-based LiDAR to observe in near real time the air-pollution plume produced when SpaceX Falcon 9 debris burned up on re‑entry. The lithium signal peaked at about 60 miles altitude, and the plume moved across Western Europe (Ireland to Germany) over roughly a day, while the debris crossed from Ireland to Poland in about 2.5 minutes. Lithium is a rare tracer in the atmosphere; the team estimates about 80 grams of lithium enter Earth's atmosphere daily globally, with a Falcon 9 contributing roughly 30 kilograms of aluminum‑lithium hull and batteries per vehicle. Aluminum oxide formation could affect ozone and climate, and researchers plan to measure additional metals in future campaigns; the study was published February 19, 2026 in Communications Earth & Environment.

Uncontrolled Falcon 9 Reentry Deposits Lithium into Upper Atmosphere, Study Finds

Researchers using lidar near Saxony, Germany, detected a lithium plume 58–60 miles up about 20 hours after an uncontrolled Falcon 9 reentry, with lithium concentrations roughly tenfold above background; the study, published in Nature, notes that metals from spacecraft (lithium and other alloys) may alter upper-atmosphere chemistry, but the environmental impact remains uncertain and warrants further research.

Lidar vs Vision: Senate scrutiny hits Tesla's FSD push

Tesla faced pointed questions at a Senate hearing over its Full Self-Driving system and its camera-only approach, with lawmakers contrasting it with lidar-equipped rivals and pressing for federal safety standards. Tesla argued its nine-camera vision system provides redundancy, while critics highlighted the need for lidar or other sensors. The hearing contributed to a roughly 4% drop in Tesla stock for the day.
