The Supreme Court ruled Friday that Donald Trump was not authorized to implement emergency tariffs to ostensibly block illegal drug flows and offset trade deficits.

It's not immediately clear what the ruling may mean for businesses that paid various "reciprocal" tariffs that Trump changed frequently, raising and lowering rates at will during tense negotiations with the United States' biggest trade partners.

Divided 6-3, Supreme Court justices remanded the cases to lower courts, concluding that the International Emergency Economic Powers Act (IEEPA) does not give Trump power to impose tariffs.

Last night, Tesla made some hefty cuts to Cybertruck pricing in an effort to stimulate some sales. The bombastic tri-motor "Cyberbeast" is $15,000 cheaper at $99,990, albeit by dropping some previously free features like supercharging and FSD . And there's now a new $59,990 entry-level model, a dual-motor configuration with a range of 325 miles (523 km) and the same 4.1-second 0–60 mph (0-97 km/h) time as the $79,990 premium all-wheel drive version.

That actually makes the new entry-level model a good deal, at least in terms of Cybertrucks. Last year, the company introduced and then eliminated a single-motor rear-wheel drive variant, which found few takers when priced at $69,990; an extra motor for $10,000 less is quite a savings, and actually slightly cheaper than the price originally advertised for the RWD truck .

As you might expect, Tesla has made some changes to get down to the new price. The range and 0–60 mph time might be the same as the more expensive dual-motor Cybertruck, but towing capacity is reduced from 11,000 lbs (4,990 kg) to 7,000 lbs (3,175kg), and cargo capacity drops from 2,500 lbs (1,134 kg) to 2,006 lbs (910 kg).

Amazon’s cloud unit has suffered at least two outages due to errors involving its own AI tools, leading some employees to raise doubts about the US tech giant’s push to roll out these coding assistants.

Amazon Web Services experienced a 13-hour interruption to one system used by its customers in mid-December after engineers allowed its Kiro AI coding tool to make certain changes, according to four people familiar with the matter.

The people said the agentic tool, which can take autonomous actions on behalf of users, determined that the best course of action was to “delete and recreate the environment.”

Following backlash in a Hacker News thread , Microsoft deleted a blog post that critics said encouraged developers to pirate Harry Potter books to train AI models that could then be used to create AI slop.

The blog, which is archived here , was written in November 2024 by a senior product manager, Pooja Kamath. According to her LinkedIn, Kamath has been at Microsoft for more than a decade and remains with the company. In 2024, Microsoft tapped her to promote a new feature that the blog said made it easier to "add generative AI features to your own applications with just a few lines of code using Azure SQL DB, LangChain, and LLMs."

What better way to show "engaging and relatable examples" of Microsoft's new feature that would "resonate with a wide audience" than to "use a well-known dataset" like Harry Potter books, the blog said.

Welcome to Edition 8.30 of the Rocket Report! As I write this week's edition, NASA's Space Launch System rocket is undergoing a second countdown rehearsal at Kennedy Space Center, Florida. The outcome of the test will determine whether NASA has a shot at launching the Artemis II mission around the Moon next month, or if the launch will be delayed until April or later. The finicky fueling line for the rocket's core stage is the center of attention after a hydrogen leak cut short a practice countdown earlier this month.

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.

Who is actually investing in sovereign launch? No one will supplant American and Chinese dominance in the space launch arena anytime soon, but several longtime US allies now see sovereign access to space as a national security imperative, Ars reports . Taking advantage of private launch initiatives already underway within their own borders, several middle and regional powers have approved substantial government funding for commercial startups to help them reach the launch pad. Australia, Canada, Germany, and Spain are among the nations that currently lack the ability to independently put their own satellites into orbit, but they are now spending money to establish a domestic launch industry. Others talk a big game but haven’t committed the cash to back up their ambitions.

A Georgia college student named Darian DeCruise has sued OpenAI, alleging that a recently deprecated version of ChatGPT “convinced him that he was an oracle” and “pushed him into psychosis.”

This case, which was first reported by ALM , marks the 11th such known lawsuit to be filed against OpenAI that involves mental health breakdowns allegedly caused by the chatbot. Other incidents have ranged from highly questionable medical and health advice to a man who took his own life , apparently after similarly sycophantic conversations with ChatGPT.

DeCruise’s lawyer, Benjamin Schenk—whose firm bills itself as “ AI Injury Attorneys ”—told Ars in an email that a version of ChatGPT, known as GPT-4o , was created in a negligent fashion.

NASA on Thursday announced it has formally classified the 2024 crewed flight of the Starliner spacecraft as a "Type A" mishap , an acknowledgement that the test flight was a serious failure.

As part of the announcement, NASA Administrator Jared Isaacman sent an agency-wide letter that recognized the shortcomings of both Starliner's developer, Boeing, as well as the space agency itself. Starliner flew under the auspices of NASA's Commercial Crew Program, in which the agency procures astronaut transportation services to the International Space Station.

"We are taking ownership of our shortcomings," Isaacman said.

There’s something special about the gadget that "just works." Technology can open opportunities for those devices but also complicate and weigh down products that have done just fine without things like sensors and software.

So when a product like the beloved Rubik’s Cube gets stuffed with wires, processors, and rechargeable batteries, there’s demand for it to be not just on par with the original—but markedly better.

The Cubios Rubik’s WOWCube successfully breathes fresh life into the classic puzzle, but it’s also an example of when too much technology can cannibalize a gadget’s main appeal.

Diablo II is one of those storied classic PC games that's pretty much always fun to come back to—so much so that some players have put thousands of hours into the game over more than two decades. Across all those years, though, the game itself has barely changed , becoming something of a familiar, comfortable blanket of hellfire for longtime players.

That makes last week's introduction of a new playable Warlock class in Diablo II Resurrected ’s new "Reign of the Warlock" DLC a pretty big deal. And after playing through a few Acts with the Warlock over the recent holiday weekend, I found the new option to be a great excuse to come back to a game that's overdue for a shot in the arm.

War-locked in

How your Warlock build goes depends heavily on which of the three main upgrade branches you choose to go down. Of these, I found the Eldritch branch had been the most interesting and fun to explore. That's in large part because of a new skill that lets you levitate a powerful two-handed weapon in front of you while still holding a strong shield in your hands. It seems like a small change, but my relief was palpable in this playthrough as I was able to avoid these kinds of tough choices between defense and offense as I juggled my inventory.
