NASA's Apollo missions brought back moon rock samples for scientists to study. We've learned a great deal over the ensuing decades, but one enduring mystery remains. Many of those lunar samples show signs of exposure to strong magnetic fields comparable to Earth's, yet the Moon doesn't have such a field today. So, how did the moon rocks get their magnetism?
There have been many attempts to explain this anomaly. The latest comes from MIT scientists, who argue in a new paper published in the journal Science Advances that a large asteroid impact briefly boosted the Moon's early weak magnetic field—and that this spike is what is recorded in some lunar samples.
Evidence gleaned from orbiting spacecraft observations, as well as results announced earlier this year from China's Chang'e 5 and Chang'e 6 missions, is largely consistent with the existence of at least a weak magnetic field on the early Moon. But where did this field come from? These usually form in planetary bodies as a result of a dynamo, in which molten metals in the core start to convect thanks to slowly dissipating heat. The problem is that the early Moon's small core had a mantle that wasn't much cooler than its core, so there would not have been significant convection to produce a sufficiently strong dynamo.
On Tuesday, Google launched Veo 3, a new AI video synthesis model that can do something no major AI video generator has been able to do before: create a synchronized audio track. While from 2022 to 2024, we saw early steps in AI video generation, each video was silent and usually very short in duration. Now you can hear voices, dialog, and sound effects in eight-second high-definition video clips.
Shortly after the new launch, people began asking the most obvious benchmarking question: How good is Veo 3 at faking Oscar-winning actor Will Smith at eating spaghetti?
First, a brief recap. The spaghetti benchmark in AI video traces its origins back to March 2023, when we first covered an early example of horrific AI-generated video using an open source video synthesis model called ModelScope. The spaghetti example later became well-known enough that Smith parodied it almost a year later in February 2024.
Last week, Elon Musk’s AI chatbot Grok experienced a “bug” that made it tell users about the “white genocide” conspiracy theory in South Africa, even when prompted with questions that had nothing to do with the topic … and soon after, Grok expressed skepticism over the Holocaust death toll, which it chalked up to a “programming […]
A few years ago, Apple published a series of short videos on its British YouTube channel that were very different from the company’s usual campaigns. Now, the company is at it again, with a new set of futuristic and oddly hypnotic ads.
“The FAA conducted a comprehensive safety review of the SpaceX Starship Flight 8 mishap and determined that the company has satisfactorily addressed the causes of the mishap, and therefore, the Starship vehicle can return to flight,” the FAA said in a statement released yesterday.
Similar to how SpaceX’s 7th Starship test flight played out in January, Flight 8 saw the ship successfully separate from the Super Heavy booster rocket that returned to the launch site at Starbase in Boca Chica, Texas where it was caught by the launch tower. But at around nine minutes into its flight, Starship began to tumble and eventually exploded before reaching its engine cutoff stage.
Previously failed test flights resulted in Starship debris raining down over Turks and Caicos and parts of the Bahamas. Although SpaceX has said the debris has been limited to pre-planned Debris Response Areas, on multiple occasions the FAA has briefly slowed and diverted flights, and initiated full ground stops at several Florida airports.
SpaceX plans to reuse a previously launched Super Heavy booster rocket for the first time for Flight 9 – specifically the rocket from Flight 7. As a result, the FAA is expanding the Aircraft Hazard Area (AHA) as an added safety precaution. For Flight 8, the AHA covered approximately 885 nautical miles. For Flight 9, it’s nearly twice the size at 1,600 nautical miles and covers parts of Texas and Florida, as well as the Bahamas and Turks and Caicos.
In addition to expanding the hazard area, the FAA is also requiring the Flight 9 launch window “to be scheduled during non-peak transit periods” in order to “minimize disruption to U.S. and international airspace users.”
Thursday’s update follows the FAA’s decision to issue a launch license earlier this month for SpaceX’s 9th Starship test flight and modify the license to expand the company’s annual operations. “The approval includes final action allowing SpaceX to increase Starship operations from five up to 25 per year at Boca Chica, Texas.”
The FAA is still without a leader after Michael Whitaker stepped down as its administrator on January 20th following clashes with Elon Musk.

OpenAI is updating the AI model powering Operator, its AI agent that can autonomously browse the web and use certain software within a cloud-hosted virtual machine to fulfill users’ requests. Soon, Operator will use a model based on o3, one of the latest in OpenAI’s o series of “reasoning” models. Previously, Operator relied on a custom […]
The first thing I noticed about the Fujifilm X Half is just how small and light it is. The camera is designed to give you no excuses - you should be able to bring it with you everywhere. And after spending a few hours walking around LA with the camera, I'm starting to understand why you'd want to.
Fujifilm's latest doesn't necessarily impress on paper. The X Half is an $850 camera with a vertically oriented 1-inch sensor capable of taking 18MP photos. There's no electric or hybrid viewfinder, no stabilization, no hot shoe, and it can't even take RAW photos. It's very easy to look at that list of missing features and disregard the camera altogether.
But the X Half's simplicity is very much the point. This is a camera for taking scrappy, quick photos and capturing memories. A lot of its flaws are masked with film simulations, filters, and superimposed grain. Its limitations are a feature, not a bug.
The camera comes with a fixed 32mm equivalent f/2.8 lens. Even with all the added grain and filters turned off, I found it to perform very well. The dynamic range is acceptable with natural highlight falloff, edges are sharp, and there's even some bokeh if you plan accor …
Xiaomi has retaken the digital crown in the global wearable band market, surpassing Apple to become the top vendor in Q1 2025, according to new data from Canalys.
The research firm says Xiaomi pulled it with a more mature ecosystem strategy than the one it had back in mid-2021 (the last time it led the pack), while Apple’s wearable strategy has grown stale.
One of Microsoft’s latest AI models can accurately predict air quality, hurricanes, typhoons, and other weather-related phenomena, the company claims. In a paper published in the journal Nature and an accompanying blog post this week, Microsoft detailed Aurora, which the tech giant says can forecast atmospheric events with greater precision and speed than traditional meteorological […]
