Nvidia announced plans today to manufacture AI chips and build complete supercomputers on US soil for the first time, commissioning over one million square feet of manufacturing space across Arizona and Texas. The politically timed move comes amid rising US-China tensions and the Trump administration's push for domestic manufacturing.

Nvidia's announcement comes less than two weeks after the Trump administration's chaotic rollout of new tariffs and just two days after the administration's contradictory messages on electronic component exemptions.

On Friday night, the US Customs and Border Protection posted a bulletin exempting electronics including smartphones, computers, and semiconductors from Trump's steep reciprocal tariffs. But by Sunday, Trump and his commerce secretary Howard Lutnick contradicted this move, claiming the exemptions were only temporary and that electronics would face new "semiconductor tariffs" in the coming months .

What a difference a week makes. This past weekend, Formula 1 went back to Bahrain, the site of this year's preseason test, for round four of the 2025 season. Last week's race in Japan sent many to sleep, but that was definitely not the case on Sunday. The overtaking was frenetic, the sparks didn't set anything on fire, and the title fight just got that little bit more complicated. It was a heck of a race.

V10s? Not any time soon

Before the racing got underway, the sport got some clarity on future powertrain rules. An ambitious new ruleset goes into effect next year, with an all-new small-capacity turbocharged V6 engine working together with an electric motor that powers the rear wheels. Just under half the total power comes from the hybrid system, much more than the two hybrid systems on current F1 cars, and developing them is no easy task . Nor is it cheap.

F1 is also moving to supposedly carbon-neutral synthetic fuels next year, and that has prompted some to wonder—increasingly loudly—if instead of the expensive hybrids lasting for four years, maybe they could be replaced with a cheaper non-hybrid engine instead, like a naturally aspirated V10 .

The colonial victory against the British in the American Revolutionary War was far from a predetermined outcome. In addition to good strategy and the timely appearance of key allies like the French, Continental soldiers relied on several key technological innovations in weaponry. But just how accurate is an 18th-century musket when it comes to hitting a target? Did the rifle really determine the outcome of the war? And just how much damage did cannon inflict? A team of military weapons experts and re-enactors set about testing some of those questions in a new NOVA documentary, Revolutionary War Weapons .

The documentary examines the firing range and accuracy of Brown Bess muskets and long rifles used by both the British and the Continental Army during the Battles of Lexington and Concord ; the effectiveness of Native American tomahawks for close combat (no, they were usually not thrown as depicted in so many popular films, but there are modern throwing competitions today); and the effectiveness of cannons against the gabions and other defenses employed to protect the British fortress during the pivotal Siege of Yorktown . There is even a fascinating segment on the first military submarine, dubbed " the Turtle ," created by American inventor David Bushnell.

To capture all the high-speed ballistics action, director Stuart Powell relied upon a range of high-speed cameras called the Phantom Range. "It is like a supercomputer," Powell told Ars. "It is a camera, but it doesn't feel like a camera. You need to be really well-coordinated on the day when you're using it because it bursts for, like, 10 seconds. It doesn't record constantly because it's taking so much data. Depending on what the frame rate is, you only get a certain amount of time. So you're trying to coordinate that with someone trying to fire a 250-year-old piece of technology. If the gun doesn't go off, if something goes wrong on set, you'll miss it. Then it takes five minutes to reboot and get ready for the new shot. So a lot of the shoot revolves around the camera; that's not normally the case."
