Critics are questioning if Donald Trump's administration possibly used chatbots to calculate reciprocal tariffs announced yesterday that Trump claimed were "individualized" tariffs placed on countries that have " the largest trade deficits" with the US.

Those tariffs are due to take effect on April 9 for 60 countries, with peak rates around 50 percent. That's in addition to a baseline 10 percent tariff that all countries will be subject to starting on April 5. But while Trump expressed intent to push back on anyone supposedly taking advantage of the US, some of the countries on the reciprocal tariffs list puzzled experts and officials, who pointed out to The Guardian that Trump was, for some reason, targeting uninhabited islands, some of them exporting nothing and populated with penguins.

Some overseas officials challenged Trump's math, such as George Plant, the administrator of Norfolk Island, who told the Guardian that "there are no known exports from Norfolk Island to the United States and no tariffs or known non-tariff trade barriers on goods coming to Norfolk Island."

SpaceX is having trouble with Starship's upper stage after back-to-back failures, but engineers are making remarkable progress with the rocket's enormous booster.

The most visible sign of SpaceX making headway with Starship's first stage—called Super Heavy—came at 9:40 am local time (10:40 am EDT; 14:40 UTC) Thursday at the company's Starbase launch site in South Texas. With an unmistakable blast of orange exhaust, SpaceX fired up a Super Heavy booster that has already flown to the edge of space. The burn lasted approximately eight seconds.

This was the first time SpaceX has test-fired a "flight-proven" Super Heavy booster, and it paves the way for this particular rocket—designated Booster 14—to fly again soon. SpaceX confirmed a reflight of Booster 14, which previously launched and returned to Earth in January, will happen on next Starship launch With Thursday's static fire test, Booster 14 appears to be closer to flight readiness than any of the boosters in SpaceX's factory, which is a short distance from the launch site.

This spring, YouTube is launching new creation tools that will make it even easier to start creating Shorts. Here’s just a few of the updates:New and improved video edit…

Most of Google's AI efforts thus far have involved adding generative features to existing products, but NotebookLM is different. Created by the Google Labs team, NotebookLM uses AI to analyze user-provided documents. Starting today, it will be even easier to use NotebookLM to explore topics, as Google has added a "Discover Sources" feature to let the app look up its own sources.

Previously, to create a new notebook, you had to feed the AI documents, web links, YouTube videos, or raw text. You can still do that, but you don't have to with the addition of Discover functionality. Simply click the new button and tell NotebookLM what you're interested in learning. Google says the app will consider "hundreds of potential web sources" in the blink of an eye, giving you the top 10 from which to choose. There will be links available so you can peruse the suggestions before adding them to the model.

The sources you select will be ingested as if they were documents you uploaded, creating a conversant AI for your chosen topic. The content of those sources will also be loaded into NotebookLM so you can refer to them directly. That's not why you use NotebookLM, though. You use NotebookLM for all the nifty AI-assisted features.

New 25 percent tariffs on all foreign car imports into the United States went into effect this week as President Trump ignited his new trade war. It has caused something of a rush at dealerships around the country as customers descend on existing stock in an attempt to beat looming price increases of thousands of dollars. Now we're starting to see how the automakers are reacting.

Employee pricing for all

Ford is in the rather enviable position of having the least exposure to the new vehicle tariff than all but Tesla; less than 20 percent of the cars, trucks, and SUVs that Ford sells in the US are imported from abroad. And it will lean into that with a new ad campaign with the slogan "From America, For America," which launches today. (Note that this does not take into account the separate parts tariff that goes into effect before May 2.)

Never mind the slogan, though. The campaign extends Ford's "A plan" pricing, which in plain English is its employee discount, to all its customers. The blue oval is offering A plan pricing on most 2024 and 2025 vehicles, including the all-electric F-150 Lightning and the Mustang Mach-E, as well as its various hybrids.

Artificial general intelligence (AGI), AI that’s at least as capable as humans at most cognitive tasks, could be here within the coming years. It has the power to transf…

US experts who work in artificial intelligence fields seem to have a much rosier outlook on AI than the rest of us.

In a survey comparing views of a nationally representative sample (5,410) of the general public to a sample of 1,013 AI experts, the Pew Research Center found that "experts are far more positive and enthusiastic about AI than the public" and "far more likely than Americans overall to believe AI will have a very or somewhat positive impact on the United States over the next 20 years" (56 percent vs. 17 percent). And perhaps most glaringly, 76 percent of experts believe these technologies will benefit them personally rather than harm them (15 percent).

The public does not share this confidence. Only about 11 percent of the public says that "they are more excited than concerned about the increased use of AI in daily life." They're much more likely (51 percent) to say they're more concerned than excited, whereas only 15 percent of experts shared that pessimism. Unlike the majority of experts, just 24 percent of the public thinks AI will be good for them, whereas nearly half the public anticipates they will be personally harmed by AI.

The US is barreling toward a recession for no good reason, and dragging the world—and a few thousand penguins on remote Antarctic islands—down with it.

A study released on Wednesday finds that a live-virus vaccine that limits shingles symptoms was associated with a drop in the risk for dementia when it was introduced. The work took advantage of the fact that the National Health Service Wales made the vaccine available with a very specific age limit, essentially creating two populations, vaccinated and unvaccinated, separated by a single date. And these populations showed a sharp divide in how often they were diagnosed with dementia, despite having little in the way of other differences in health issues or treatments.

What a day

This study didn't come out of nowhere. There have been a number of hints recently that members of the herpesvirus family that can infect nerve cells are associated with dementia. That group includes Varicella zoster, the virus that causes both chicken pox and—potentially many years after— shingles, an extremely painful rash. And over the past couple of years, observational studies have suggested that the vaccine against shingles may have a protective effect.

But it's extremely difficult to do a clinical trial given that the onset of dementia may happen decades after most people first receive the shingles vaccine. That's why the use of NHS Wales data was critical. When the first attenuated virus vaccine for shingles became available, it was offered to a subset of the Welsh population. Those who were born on or after September 2, 1933, were eligible to receive the vaccine. Anyone older than that was permanently ineligible.

The hoodie is a work-from-home security blanket. But in the office, it’s a trap.

Among the changes mentioned in yesterday's Nintendo Switch 2 presentation was a note that the new console doesn't just support MicroSD Express cards for augmenting the device's 256GB of internal storage, but it requires MicroSD Express. Whatever plentiful, cheap microSD card you're using in your current Switch, including Sandisk's Nintendo-branded ones, can't migrate over to your Switch 2 alongside all your Switch 1 games.

MicroSD Express, explained

Why is regular-old MicroSD no longer good enough? It all comes down to speed.

Most run-of-the-mill SD and microSD cards you can buy today are using some version of the Ultra High Speed (UHS) standard. Designed to augment the default speed (12.5MB/s) and high speed (25MB/s) from the earliest versions of the SD card standard, the three UHS versions enable data transfers of up to 624MB/s.

Samsung has turned to Chinese technology groups to prop up its ailing semiconductor division, as it struggles to secure big US customers despite investing tens of billions of dollars in its American manufacturing facilities.

The South Korean electronics group revealed last month that the value of its exports to China jumped 54 percent between 2023 and 2024, as Chinese companies rush to secure stockpiles of advanced artificial intelligence chips in the face of increasingly restrictive US export controls.

In one previously unreported deal, Samsung last year sold more than three years’ supply of logic dies—a key component in manufacturing AI chips—to Kunlun, the semiconductor design subsidiary of Chinese tech group Baidu, according to people familiar with the matter.

The Nintendo Switch 2 could be considered the most direct "sequel" to a Nintendo console that the company has ever made. The lineage is right there in the name, with Nintendo simply appending the number "2" onto the name of its incredibly successful previous console for the first time in its history.

Nintendo's previous consoles have all differed from their predecessors in novel ways that were reflected in somewhat new naming conventions. The Switch 2's name, on the other hand, suggests that it is content to primarily be "more Switch." And after spending the better part of the day playing around with the Switch 2 hardware and checking out some short game demos on Wednesday, I indeed came away with the impression that this console is "more Switch" in pretty much every way that matters, for better or worse.

Bigger is better

We've deduced from previous trailers just how much bigger the Switch 2 would be than the original Switch. Even with that preparation, though, the expanded Switch 2 makes a very good first impression in person.
