I found myself in the air long enough to give some thought to how I could land while remaining atop the bicycle I had been riding the instant before I hit the jump. Based on similar experiences while skiing, I immediately recognized that this invariably meant very bad things. A few seconds later, as I was brushing dirt out of the abrasions I had just picked up, I contemplated where I had gone wrong.

Once again, I had misunderstood HPC's Trailblazer e-mountain bike. Doing so had become a feature of the time I spent using the bike.

The Trailblazer looks like a solid, hefty beast of a bike (that's not an insult—I got compliments on its looks while taking a train to some trails). It's covered with components that are likely to be unfamiliar to people who know the default sets that come with bikes from large manufacturers. But if you do some research on the components, you realize that the Trailblazer was specced by someone with deep knowledge and fairly particular tastes. And the ride the bike provided has some surprisingly subtle qualities that took me a while to adjust to.

Google has sued two app developers based in China over an alleged scheme targeting 100,000 users globally over four years with at least 87 fraudulent cryptocurrency and other investor apps distributed through the Play Store.

The tech giant alleged that scammers lured victims with "promises of high returns" from "seemingly legitimate" apps offering investment opportunities in cryptocurrencies and other products. Commonly known as "pig-butchering schemes," these scams displayed fake returns on investments, but when users went to withdraw the funds, they discovered they could not.

In some cases, Google alleged, developers would "double down on the scheme by requesting various fees and other payments from victims that were supposedly necessary for the victims to recover their principal investments and purported gains."

A scientific journal published by Elsevier has reportedly posted a stunning 101 expressions of concern on studies connected to Didier Raoult, a disgraced French microbiologist who gained international prominence amid the pandemic by promoting, with little evidence, that the malaria drug hydroxychloroquine could treat COVID-19—a claim that has now been firmly debunked.

According to Retraction Watch, the journal New Microbes and New Infections posted 101 expressions of concern on Raoult's works recently, including a 2023 study that drew sharp criticism. The study involved giving hydroxychloroquine to tens of thousands of COVID-19 patients after data indicated that it wasn't effective and the French government rescinded permission for its use against COVID-19. An op-ed in the major French newspaper Le Monde described the study as "the largest 'wild' therapeutic trial known to date."

The expressions of concern also come as Raoult saw his tenth study retracted, Retraction Watch noted.

Your next food delivery driver may be a robot.

Waymo and Uber have been working together on regular Ubers for a while, but the two companies are now teaming up for food delivery. Automated Uber Eats is rolling out to Waymo's Phoenix service area. Waymo says this will start in "select merchants in Chandler, Tempe and Mesa, including local favorites like Princess Pita, Filiberto's, and Bosa Donuts."

Phoenix Uber Eats customers can fire up the app and order some food, and they might see the message “autonomous vehicles may deliver your order.” Waymo says you'll be able to opt out of robot delivery at checkout if you want.

Old-school user-controlled memory management is back, baby!

Or at least it's a feature Microsoft is testing in the newest builds of its Chromium-based Edge browser (via The Verge). User Leopeva64 on X, formerly Twitter, posted screenshots of an Edge build with a "resource controls" slider for manually limiting the browser's RAM usage. There's also a toggle to set whether you want RAM limits to kick in when you're playing a game, or if you want the limit to be enforced at all times.

It builds on a feature that's already in the stable version of Edge, where the browser will alert you if an individual tab has particularly high memory usage. The minimum limit you can set for Edge appears to be 1GB, and it goes all the way up to the amount of physical memory you have installed in your PC.

For most people, Windows 10 will stop receiving critical security updates on October 14, 2025, roughly a decade after its initial release. For people using computers that can't upgrade to Windows 11 or organizations with dozens or hundreds of PCs to manage, Microsoft is making another three years of Extended Security Updates (ESUs) available, but only if you can pay for them. And the company is ready to start talking about pricing.

In a blog post published earlier this week, Microsoft's Jason Leznek writes that the first year of ESUs will cost $61 per PC for businesses that want to keep their systems updated.

And as with the Windows 7 ESUs a few years ago, Microsoft says that the price will double each year—so the second year of ESUs will cost $122 per PC, and the third year will cost a whopping $244 per device. And Microsoft says this pricing is cumulative; if you decided to buy ESUs for year three after skipping the first two years, you'd also need to pay for the first two years retroactively. These slow price hikes seem intended to drive businesses to migrate to Windows 11 as quickly as they can while still giving them a way to keep using Windows 10 when absolutely necessary.

An international collaboration of scientists has created the largest 3D map of our universe to date based on the first results from the Dark Energy Spectroscopic Instrument (DESI). It's an impressive achievement, with more to come, but the most significant finding stems from the collaboration's new measurements of dark energy. Those results roughly agree with the current prevailing theoretical model for dark energy, in which dark energy is constant over time. But there are some tantalizing hints that it could vary over time instead, which would call for some changes to that prevailing model.

Granted, those hints are still below the necessary threshold to claim discovery and hence fall under the rubric of "huge, if true." We'll have to wait for more data from DESI's continuing measurements to see if they hold up. In the meantime, multiple papers delving into the technical details behind these first results have been posted to the arXiv, and there will be several talks presented at a meeting of the American Physical Society being held this week in Sacramento, California, as well as at Rencontres de Moriond in Italy.

“Our results show some interesting deviations from the standard model of the universe that could indicate that dark energy is evolving over time,” said Mustapha Ishak-Boushaki, a physicist at the University of Texas, Dallas, and a member of the DESI collaboration. “The more data we collect, the better equipped we will be to determine whether this finding holds. With more data, we might identify different explanations for the result we observe or confirm it. If it persists, such a result will shed some light on what is causing cosmic acceleration and provide a huge step in understanding the evolution of our universe.”
