Mystery Drone Sightings Lead to FAA Ban Despite No Detected Threats
Exploring an undersea terrain sculpted by glaciers and volcanoes
On May 2, 2008, the Chaitén volcano in Chile awoke with unexpected fury after more than 9,000 years of dormancy. The eruption blasted rocks and ash a dozen miles into the air, and then heavy rainfall swept the fallen debris up in immense mudflows. A river of rubble carved a destructive path through the nearby town of Chaitén before surging into the sea. The town, practically split in two by the torrent that cut through its middle, was evacuated as ash blanketed over 200,000 square kilometers of surrounding land.
While the terrestrial aftermath was plain to see, captured by both the local media and satellites, the impact on the sea was unknown.

The debris flowed through rivers into the Northern Patagonian Sea, just six miles away.

12 days of OpenAI: The Ars Technica recap
Over the past 12 business days, OpenAI has announced a new product or demoed an AI feature every weekday, calling the PR event "12 days of OpenAI." We've covered some of the major announcements, but we thought a look at each announcement might be useful for people seeking a comprehensive look at each day's developments.
The timing and rapid pace of these announcements—particularly in light of Google's competing releases—illustrates the intensifying competition in AI development. What might normally have been spread across months was compressed into just 12 business days, giving users and developers a lot to process as they head into 2025.
Humorously, we asked ChatGPT what it thought about the whole series of announcements, and it was skeptical that the event even took place. "The rapid-fire announcements over 12 days seem plausible," wrote ChatGPT-4o, "But might strain credibility without a clearer explanation of how OpenAI managed such an intense release schedule, especially given the complexity of the features."

2024 Was the Year the Bottom Fell Out of the Games Industry
Horizon: Zero Dawn gets the graphical remaster a modern classic deserves
At their best, "remastered" video games keep terrific older titles viable on new generations of hardware and for new generations of fans. At their worst, they can feel like a cash-in.
So it was with some trepidation that I recently fired up the "remastered" Horizon: Zero Dawn, a game which won me over years ago with its PS4 version due to the simple fact that it was ONE OF THE BEST VIDEO GAMES OF ALL TIME and featured ONE OF THE BEST PROTAGONISTS OF ALL TIME in one of the BEST STORIES OF ALL TIME. (Yes, I like superlatives, which are some of the BEST WORDS OF ALL TIME. But the game world really was terrific.) Even my kids were won over, playing through the game and its sequel multiple times.
The game tells the story of a future Earth long after catastrophe—in the form of an autonomous robotic swarm—has ruined the planet. But it's not mere dystopia, though one does come across many wrecked and overgrown spaces from that earlier age. Horizon instead focuses on how humans, having lost most of their past knowledge, rebuilt a world in tribal fashion, a world populated by animal-inspired machines. The game's story operates ambitiously in two timelines and features massive killer robots, cults, and mad Sun Kings, all set against the gorgeous background of the American West.
Rocket Report: ULA has a wild idea; Starliner crew will stay in orbit even longer
Welcome to Edition 7.24 of the Rocket Report! This is the last Rocket Report of the year, and what a year it's been. So far, there have been 244 rocket launches to successfully reach orbit this year, a record for annual launch activity. And there are still a couple of weeks to go before the calendar turns to 2025. Time is running out for Blue Origin to launch its first heavy-lift New Glenn rocket this year, but if it flies before January 1, it will certainly be one of the top space stories of 2024.
As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.
Corkscrew in the sky. A Japanese space startup said its second attempt to launch a rocket carrying small satellites into orbit had been terminated minutes after liftoff Wednesday and destroyed itself again, nine months after the company’s first launch attempt in an explosion, the Associated Press reports. The startup that developed the rocket, named Space One, launched the Kairos rocket from a privately owned coastal spaceport in Japan's Kansai region. Company executive and space engineer Mamoru Endo said an abnormality in the first stage engine nozzle or its control system is likely to have caused an unstable flight of the rocket, which started spiraling in mid-flight and eventually destroyed itself about three minutes after liftoff, using its autonomous safety mechanism.
OpenAI announces o3 and o3-mini, its next simulated reasoning models
On Friday, during Day 12 of its "12 days of OpenAI," OpenAI CEO Sam Altman announced its latest AI "reasoning" models, o3 and o3-mini, which build upon the o1 models launched earlier this year. The company is not releasing them yet but will make these models available for public safety testing and research access today.
The models use what OpenAI calls "private chain of thought," where the model pauses to examine its internal dialog and plan ahead before responding, which you might call "simulated reasoning" (SR)—a form of AI that goes beyond basic large language models (LLMs).
The company named the model family "o3" instead of "o2" to avoid potential trademark conflicts with British telecom provider O2, according to The Information. During Friday's livestream, Altman acknowledged his company's naming foibles, saying, "In the grand tradition of OpenAI being really, truly bad at names, it'll be called o3."
Startup set to brick $800 kids robot is trying to open source it first
Earlier this month, startup Embodied announced that it is going out of business and taking its Moxie robot with it. The $800 robots, aimed at providing emotional support for kids ages 5 to 10, would soon be bricked, the company said, because they can’t perform their core features without the cloud. Following customer backlash, Embodied is trying to create a way for the robots to live an open sourced second life.
Embodied CEO Paolo Pirjanian shared a document via a LinkedIn blog post today saying that people who used to be part of Embodied’s technical team are developing a “potential” and open source way to keep Moxies running. The document reads:
This initiative involves developing a local server application (‘OpenMoxie’) that you can run on your own computer. Once available, this community-driven option will enable you (or technically inclined individuals) to maintain Moxie’s basic functionality, develop new features, and modify her capabilities to better suit your needs—without reliance on Embodied’s cloud servers.
The notice says that after releasing OpenMoxie, Embodied plans to release “all necessary code and documentation” for developers and users.

Man who claims he invented bitcoin faces prison after filing $1.1 trillion suit
Craig Wright, the man who claims he invented bitcoin and has been filing lawsuits asserting intellectual property rights, was sentenced to a year in prison yesterday for committing contempt of court.
The sentence is suspended and can be enforced if Wright continues violating court rulings—but he may be able to avoid imprisonment by staying away from countries that have extradition agreements with the UK. Wright defied an order to attend a court hearing in person this week and said he is in Asia.
Wright "was sentenced for contempt of court on Thursday" for bringing a 911 billion pound ($1.1 trillion) lawsuit "against Twitter founder Jack Dorsey's payments company Block in Britain," Reuters wrote.
