Google released its latest and greatest Gemini AI model last week , but it was only made available to paying subscribers. Google has moved with uncharacteristic speed to release Gemini 2.5 Pro (Experimental) for free users, too. The next time you check in with Gemini, you can access most of the new AI's features without a Gemini Advanced subscription.

The Gemini 2.5 branch will eventually replace 2.0, which was only released in late 2024. It supports simulated reasoning, as all Google's models will in the future. This approach to producing an output can avoid some of the common mistakes that AI models have made in the past. We've also been impressed with Gemini 2.5's vibe, which has landed it at the top of the LMSYS Chatbot arena leaderboard .

Google says Gemini 2.5 Pro (Experimental) is ready and waiting for free users to try on the web. Simply select the model from the drop-down menu and enter your prompt to watch the "thinking" happen. The model will roll out to the mobile app for free users soon.

Oh, ExoMars, what a long, strange trip it has been. Are you ever going to go to space?

The ExoMars mission represents Europe's third attempt to land successfully on Mars, and at a cost of more than $1.3 billion. there is a lot riding on its success. But success is far from assured for a mission that has been whipsawed by geopolitical tensions, budget cuts, and an ever-changing architecture over the last 20 years.

The latest news, announced Sunday , is that Airbus will design and build the lander that will carry the ExoMars down to the surface of Mars. The mission is scheduled to launch no earlier than 2028 on a US rocket. But there have been so many twists and turns in the ExoMars story that it's very difficult to know what will ultimately happen.

The first flight of Isar Aerospace's Spectrum rocket didn't last long on Sunday. The booster's nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, punctuating the abbreviated test flight with a spectacular fiery crash into the sea.

If officials at Isar Aerospace were able to pick the outcome of their first test flight, it wouldn't be this. However, the result has precedent. The first launch of SpaceX's Falcon 1 rocket in 2006 ended in similar fashion.

"Today, we know twice as much about our launch system as yesterday before launch," Daniel Metzler, Isar's co-founder and CEO, wrote on X early Monday. "Can't beat flight testing. Ploughing through lots of data now."

Big brands are allocating small amounts of their advertising budget to Elon Musk’s X, seeking to avoid being seen as boycotting the social media platform and triggering a public fallout with its billionaire owner.

Multiple marketing executives told the Financial Times that companies have felt pressure to spend a nominal sum on X following Musk’s high-profile role in US President Donald Trump’s administration.

They said Musk’s pursuit of legal action against groups that have stopped advertising since his $44 billion acquisition in late 2022 had also sparked alarm. X last month added about half a dozen more companies to its case including Shell, Nestlé, Pinterest, and Lego.

Late last week, President Donald Trump decided to upend the automotive industry by levying a new 25 percent import tariff on all imported cars , which goes into effect on April 2. An additional 25 percent tariff on car parts is set to go into effect within the next month, which promises to make US-made cars more expensive as well, as many parts and subassemblies used in domestic manufacturing come from suppliers in Canada or Mexico.

During the election campaign (and in the years preceding it), Trump repeatedly claimed that the cost of tariffs would be borne by the exporters. But tariffs don't work that way—they're paid by the importer, at the time of import.

The White House does not appear to have any concerns about this, despite a report in The Wall Street Journal last week claiming that Trump had warned automakers not to pass the costs on to their customers.

QLED TV manufacturers have dug themselves into a hole.

After years of companies promising that their quantum dot light-emitting diode TVs use quantum dots (QDs) to boost color, some industry watchers and consumers have recently started questioning whether QLED TVs use QDs at all. Lawsuits have been filed, accusing companies like TCL of using misleading language about whether their QLED TVs actually use QDs.

In this article, we'll break down why new conspiracy theories about QLED TVs are probably overblown. We'll also explore why misleading marketing from TV brands is responsible for customer doubt and how it all sets a bad precedent for the future of high-end displays, including OLED TVs and monitors.

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering , a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles here , here , and here .

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The discovery is one of the most significant findings in the search for evidence of past life on Mars. This is because, on Earth at least, relatively complex, long-chain carbon molecules are involved in biology. These molecules could actually be fragments of fatty acids, which are found in, for example, the membranes surrounding biological cells.

Scientists think that, if life ever emerged on Mars, it was probably microbial in nature. Because microbes are so small, it’s difficult to be definitive about any potential evidence for life found on Mars. Such evidence needs more powerful scientific instruments that are too large to be put on a rover.

The organic molecules found by Curiosity consist of carbon atoms linked in long chains, with other elements bonded to them, like hydrogen and oxygen. They come from a 3.7-billion-year-old rock dubbed Cumberland, encountered by the rover at a presumed dried-up lakebed in Mars’s Gale Crater. Scientists used the Sample Analysis at Mars (SAM) instrument on the NASA rover to make their discovery.

Windows 11 made our recent roundup of our least favorite "enshittified" products , which will come as no surprise to those of you who have followed our coverage of it over the years. What began as a more visually cohesive coat of paint for Windows 10 has given way to a user experience that has gradually coasted downhill even as it has picked up new features—a "clean install" of the operating system is pretty annoying, at a baseline, even before you consider extra software irritations from your PC, motherboard maker, or Microsoft's all-encompassing push into generative AI.

We'll never stop asking Microsoft to put out a consumer version of Windows that acts more like the Enterprise versions it gives to businesses, with no extra unasked-for apps and less pushiness about Microsoft's other products and services. But given that most of us are saddled with the current consumer-facing versions of Windows—Home and Pro, which treat their users basically the same way despite the difference in cost and branding—we're updating our guide to cleaning up a "clean install" to account for Windows 11 24H2 and any other changes Microsoft has made in the last year.

As before, this is not a guide about creating an extremely stripped-down, telemetry-free version of Windows; we stick to the things that Microsoft officially supports turning off and removing. There are plenty of experimental hacks that take it a few steps farther—NTDev's Tiny11 project is one—but removing built-in Windows components can cause unexpected compatibility and security problems, and Tiny11 has historically had issues with basic table-stakes stuff like "installing security updates."
