Scientists test underwater “LarvalBot” in effort to rebuild coral reefs damaged by climate change
An underwater robot previously used to eliminate invasive species in coral reefs has been repurposed to spread baby coral larvae where needed. Renamed “LarvalBot” from its previous “RangerBot” title, this machine is currently the only one of its kind, and it represents an important step in the direction of coral reef restoration. The machine was developed by scientists from Queensland University of Technology (QUT) and Southern Cross University (SCU) in Australia with funding from the Great Barrier Reef Foundation.
The technique used by the bot is called “larval restoration”, and it begins with the collection of millions of coral spawn by scientists. The spawn are next reared inside nearby large floating enclosures, and once they have developed into larvae, the coral young are put into LarvalBot and squirted around dead reef areas. From there, the baby coral can settle, grow, and gradually restore damage from events like coral bleaching. It will take about three years for the corals to become mature enough to reproduce and spread on their own.
With LarvalBot’s assistance, the spread of coral larvae will be enhanced up to 100-times what is achieved naturally. Given the unnatural threats of destructive fishing practices and pollution to the reefs, artificial means of helping nature may be the only way they can hope to survive in the long-term. Scientists from QUT and SCU are currently focused on speeding up the recovery of parts of the Great Barrier Reef affected by coral bleaching, a condition which occurs after coral lose their symbiotic algae, causing the living tissues to become transparent.

Coral bleaching will kill the corals affected if the environmental cause continues for too long. There are several stressors which can lead to the bleaching; however, the leading cause today is warming temperatures. A difference of two degrees Fahrenheit above the seasonal maximum can trigger the condition.
The upcoming annual season for coral spawning occurs in late November where the corals will synchronically bloom all over the world. Triggered by the lunar cycle and water temperature, coral reef colonies will release their eggs and sperm in a mass event resulting in clouds of white, yellow, and orange in all reef regions. After the blooms rise to the surface where fertilization occurs, the embryos develop into larvae, and then they fall to the sea floor in the days and weeks following where they will hopefully attach to substrate and grow into a new colony.
LarvalBot’s developers hope to have 2-3 similar robots ready to help collect the blooms resulting from the November event. According to these scientists, the bots will carry about 200,000 and 1.2 million larvae apiece and seed the reefs at a rate of 1500 square meters per hour. It’s not quite enough to consider the bots official coral baby mothers, but perhaps the actions could be considered motherly.

Tesla Robotaxi’s biggest rival sends latest statement with big expansion
The new expanded geofence now covers a broader region of Austin and its metropolitan areas, extended south to Manchaca and north beyond US-183.
Tesla Robotaxi’s biggest rival sent its latest statement earlier this month by making a big expansion to its geofence, pushing the limits up by over 50 percent and nearing Tesla’s size.
Waymo announced earlier this month that it was expanding its geofence in Austin by slightly over 50 percent, now servicing an area of 140 square miles, over the previous 90 square miles that it has been operating in since July 2025.
Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’
The new expanded geofence now covers a broader region of Austin and its metropolitan areas, extended south to Manchaca and north beyond US-183.
These rides are fully driverless, which sets them apart from Tesla slightly. Tesla operates its Robotaxi program in Austin with a Safety Monitor in the passenger’s seat on local roads and in the driver’s seat for highway routes.
It has also tested fully driverless Robotaxi services internally in recent weeks, hoping to remove Safety Monitors in the near future, after hoping to do so by the end of 2025.

Although Waymo’s geofence has expanded considerably, it still falls short of Tesla’s by roughly 31 square miles, as the company’s expansion back in late 2025 put it up to roughly 171 square miles.
There are several differences between the two operations apart from the size of the geofence and the fact that Waymo is able to operate autonomously.
Waymo emphasizes mature, fully autonomous operations in a denser but smaller area, while Tesla focuses on more extensive coverage and fleet scaling potential, especially with the potential release of Cybercab and a recently reached milestone of 200 Robotaxis in its fleet across Austin and the Bay Area.
However, the two companies are striving to achieve the same goal, which is expanding the availability of driverless ride-sharing options across the United States, starting with large cities like Austin and the San Francisco Bay Area. Waymo also operates in other cities, like Las Vegas, Los Angeles, Orlando, Phoenix, and Atlanta, among others.
Tesla is working to expand to more cities as well, and is hoping to launch in Miami, Houston, Phoenix, Las Vegas, and Dallas.

Tesla automotive will be forgotten, but not in a bad way: investor
It’s no secret that Tesla’s automotive division has been its shining star for some time. For years, analysts and investors have focused on the next big project or vehicle release, quarterly delivery frames, and progress in self-driving cars. These have been the big categories of focus, but that will all change soon.
Entrepreneur and Angel investor Jason Calacanis believes that Tesla will one day be only a shade of how it is recognized now, as its automotive side will essentially be forgotten, but not in a bad way.
It’s no secret that Tesla’s automotive division has been its shining star for some time.

I subscribed to Tesla Full Self-Driving after four free months: here’s why
Eventually, and even now, the focus has been on real-world AI and Robotics, both through the Full Self-Driving and autonomy projects that Tesla has been working on, as well as the Optimus program, which is what Calacanis believes will be the big disruptor of the company’s automotive division.
On the All-In podcast, Calcanis revealed he had visited Tesla’s Optimus lab earlier this month, where he was able to review the Optimus Gen 3 prototype and watch teams of engineers chip away at developing what CEO Elon Musk has said will be the big product that will drive the company even further into the next few decades.
Calacanis said:
“Nobody will remember that Tesla ever made a car. They will only remember the Optimus.”
He added that Musk “is going to make a billion of those.”
Musk has stated this point himself, too. He at one point said that he predicted that “Optimus will be the biggest product of all-time by far. Nothing will even be close. I think it’ll be 10 times bigger than the next biggest product ever made.”
He has also indicated that he believes 80 percent of Tesla’s value will be Optimus.
Optimus aims to totally revolutionize the way people live, and Musk has said that working will be optional due to its presence. Tesla’s hopes for Optimus truly show a crystal clear image of the future and what could be possible with humanoid robots and AI.

Tesla Robotaxi fleet reaches new milestone that should expel common complaint
There have been many complaints in the eight months that the Robotaxi program has been active about ride availability, with many stating that they have been confronted with excessive wait times for a ride, as the fleet was very small at the beginning of its operation.
Tesla Robotaxi is active in both the Bay Area of California and Austin, Texas, and the fleet has reached a new milestone that should expel a common complaint: lack of availability.
It has now been confirmed by Robotaxi Tracker that the fleet of Tesla’s ride-sharing vehicles has reached 200, with 158 of those being available in the Bay Area and 42 more in Austin. Despite the program first launching in Texas, the company has more vehicles available in California.
The California area of operation is much larger than it is in Texas, and the vehicle fleet is larger because Tesla operates it differently; Safety Monitors sit in the driver’s seat in California while FSD navigates. In Texas, Safety Monitors sit in the passenger’s seat, but will switch seats when routing takes them on the highway.
Tesla has also started testing rides without any Safety Monitors internally.

This new milestone confronts a common complaint of Robotaxi riders in Austin and the Bay, which is vehicle availability.

I attempted to take a @robotaxi ride today from multiple different locations and time of day (from 9:00 AM to about 3:00 PM in Austin but never could do so.

With that being said, there have been some who have said wait times have improved significantly, especially in the Bay, where the fleet is much larger.
Robotaxi wait times here in Silicon Valley used to be around 15 minutes for me.
Over the past few days, they’ve been consistently under five minutes, and with scaling through the end of this year, they should drop to under two minutes. pic.twitter.com/Kbskt6lUiR

Tesla’s approach to the Robotaxi fleet has been to prioritize safety while also gathering its footing as a ride-hailing platform.
Of course, there have been and still will be growing pains, but overall, things have gone smoothly, as there have been no major incidents that would derail the company’s ability to continue developing an effective mode of transportation for people in various cities in the U.S.
Tesla plans to expand Robotaxi to more cities this year, including Miami, Las Vegas, and Houston, among several others.
