Horrifying medical device malfunction: Abdominal implant erupts from leg
Suspicious deaths, perforated sheep veins went unreported before device hit market.
On May 7, 2011, Georgia resident Tonya Brand noticed a pain on the inside of her right thigh. As the pain grew worse in the 4- to 5-inch area of her leg, she headed to a hospital. There, doctors suspected she had a blood clot. But an ultrasound the next day failed to find one. Instead, it revealed a mysterious toothpick-sized object lodged in Brand’s leg.
Over the next few weeks, the painful area became a bulge, and on June 17, Brand put pressure on it. Unexpectedly, the protrusion popped, and a 1.5-inch metal wire came poking out of her leg, piercing her skin.
The piece of metal was later determined to be part of a metal filter she had implanted in a vein in her abdomen more than two years earlier, in March 2009, according to a lawsuit Brand filed. The filter was initially placed in her inferior vena cava (IVC), the body’s largest vein tasked with bringing deoxygenated blood from the lower body back up to the heart. The filter is intended to catch blood clots, preventing them from getting into the lungs, where they could cause a life-threatening pulmonary embolism. Brand got the IVC filter ahead of a spinal surgery she had in 2009, which could boost her risk of clots.
As NASA increasingly relies on commercial space, there are some troubling signs
“The government’s really got to look at itself.”
When it comes to space policy, a hallmark of the first Trump administration was its embrace of private companies. NASA sought to build fewer expensive things and buy more lower-cost services. In doing so, it aimed to foster a healthy ecosystem of private space companies.
Under the leadership of Jim Bridenstine, NASA, during these years, stood on the shoulders of more than a decade of government investment in commercial space. This culminated in a triumphant Crew Dragon mission in the summer of 2020, the first privately led human orbital spaceflight.
This Demo-2 mission, sending NASA astronauts Doug Hurley and Bob Behnken to the International Space Station on a SpaceX vehicle, validated NASA’s long push into commercial space. Since then, the agency has only doubled down on this approach, generally using fixed-price contracts and buying a service instead of telling companies what and how to build while paying a premium.
Qubit that makes most errors obvious now available to customers
Can a small machine that makes error correction easier upend the market?
We’re nearing the end of the year, and there are typically a flood of announcements regarding quantum computers around now, in part because some companies want to live up to promised schedules. Most of these involve evolutionary improvements on previous generations of hardware. But this year, we have something new: the first company to market with a new qubit technology.
The technology is called a dual-rail qubit, and it is intended to make the most common form of error trivially easy to detect in hardware, thus making error correction far more efficient. And, while tech giant Amazon has been experimenting with them, a startup called Quantum Circuits is the first to give the public access to dual-rail qubits via a cloud service.
While the tech is interesting on its own, it also provides us with a window into how the field as a whole is thinking about getting error-corrected quantum computing to work.
Study: Why Aztec “death whistles” sound like human screams
The basic mechanism relies on the Venturi effect, producing a unique rough and piercing sound.
Archaeologists have discovered numerous ceramic or clay whistles at Aztec sites, dubbed “death whistles” because of their distinctive skull shapes. A new paper published in the journal Communications Psychology examines the acoustical elements of the unique shrieking sounds produced by those whistles, as well as how human listeners are emotionally affected by the sounds. The findings support the hypothesis that such whistles may have been used in Aztec religious rituals or perhaps as mythological symbols.
Archaeologists unearthed the first Aztec death whistles, also known as ehecachichtlis, in 1999 while excavating the Tlatelolco site in Mexico City. They found the body of a sacrificial victim, a 20-year-old male who had been beheaded, at the base of the main stairway of a temple dedicated to the wind god Ehecatl. The skeleton was clutching two ceramic skull-shaped whistles, one in each hand, along with other artifacts. More skull whistles were subsequently found, and they’ve found their way into popular culture. For instance, in Ghostbusters: Afterlife (2021), Egon Spengler had such a whistle in his secret laboratory collection.
Scholars have puzzled over the purpose of the skull whistles, although given the dearth of concrete evidence, most suggestions are highly speculative. One hypothesis is that it was used in battle, with hundreds of warriors blowing their whistles simultaneously as a battle cry. Music archaeologist Arnd Adje Both has dismissed that idea, suggesting instead that the whistle’s purpose was more likely tied to ceremonial or religious practices, like human sacrifice. Yet another hypothesis proposes that the whistles were intended as symbols of a deity. The skull shape, for instance, might allude to the Aztec god of the underworld, Mictlantecuhtli.
Microsoft pushes full-screen ads for Copilot+ PCs on Windows 10 users
Microsoft has frequently used this kind of reminder to encourage upgrades.
Windows 10’s free, guaranteed security updates stop in October 2025, less than a year from now. Windows 10 users with supported PCs have been offered the Windows 11 upgrade plenty of times before. But now Microsoft is apparently making a fresh push to get users to upgrade, sending them full-screen reminders recommending they buy new computers.
The reminders, which users have seen within the last few days, all mention the end of Windows 10 support but otherwise seem to differ from computer to computer. My Ars colleague Kyle Orland got one focused on Windows 11’s gaming features, while posters on X (formerly Twitter) got screens that emphasized the ease of migrating from old PCs to new ones and other Windows 11 features. One specifically recommended upgrading to a Copilot+ PC, which supports a handful of extra AI features that other Windows 11 PCs don’t, but other messages didn’t mention Copilot+ specifically.
None of the messages mention upgrading to Windows 11 directly, though Kyle said his PC meets Windows 11’s requirements. These messages may be intended mostly for people using older PCs that can’t officially install the Windows 11 update.
SpaceX just got exactly what it wanted from the FAA for Texas Starship launches
“All pertinent conditions and requirements of the prior approval have been met.”
A day after SpaceX launched its Starship rocket for the sixth time, the company received good news from the Federal Aviation Administration regarding future launch operations from its Starbase facility in South Texas.
In a draft version of what is known as an “Environmental Assessment,” the FAA indicated that it will grant SpaceX permission to increase the number of Starship launches in South Texas to 25 per year from the current limit of five. Additionally, the company will likely be allowed to continue increasing the size and power of the Super Heavy booster stage and Starship upper stage.
“FAA has concluded that the modification of SpaceX’s existing vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, consistent with the data contained in the 2022 PEA, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action,” the federal agency stated in its conclusion.
Fitness app Strava is tightening third-party access to user data
Training apps, AI use, and trend analysis seem to be off-limits in Strava’s API.
The Strava app is one of the most popular ways for cyclists, runners, hikers, and other distance sports enthusiasts to track their performance and grab some bragging rights. Because most athletic types will have the app installed already—and because it’s hard or impossible to run two tracking apps at once—many apps use Strava’s API as a go-between for workout data.
Strava emailed its more than 100 million users earlier this week to notify them about “important updates on how Strava data can be displayed, accessed, and used by third-party apps.” In the update, Strava noted that third-party apps “are no longer able to display your Strava activity data on their surfaces to other users,” that Strava’s API data cannot be used “in artificial intelligence models or other similar applications,” and that third-party apps must be designed so as to “complement” Strava’s look and feel “rather than replicating it.”
What does this actually mean? It depends on which apps you’re using. DC Rainmaker, a longtime fitness tech blogger, sees the “other users” clause as something that “immediately break[s] almost all coaching apps that have connections to Strava.” If an app needs to see your Strava workout to provide insights on performance or connect you to a group, Strava’s API seems to block it now. A manager at the training app Intervals posted on the app’s official forum that the API change would break Intervals’ ability to use Strava as its data source.
Comcast to ditch cable TV networks in partial spinoff of NBCUniversal assets
Comcast to spin off USA, CNBC, MSNBC, and others, will keep Peacock streaming.
Comcast today announced plans to spin off NBCUniversal cable TV networks such as USA, CNBC, and MSNBC into a new publicly traded company. Comcast is trying to complete the spinoff in one year, effectively unwinding part of the NBCUniversal acquisition it completed in 2011.
The entities in the planned spinoff generated about $7 billion of revenue in the 12 months that ended September 30, 2024, Comcast said. But cable TV channels have become less lucrative in an industry that’s shifting to the streaming model, and the spinoff would let Comcast remove those assets from its earnings reports. Comcast’s total revenue in the 12-month period was about $123 billion.
Comcast President Mike Cavanagh said in the Q3 earnings call on October 31 that Comcast is “experiencing the effects of the transition in our video businesses and have been studying the best path forward for these assets.”
Minecraft Movie trailer explores the origins of Steve
Where “anything you can imagine is possible—as long as what you imagine can be built out of blocks.”
The first teaser for A Minecraft Movie released in September to some decidedly mixed reactions, particularly concerning the CGI and character design and especially Jason Momoa’s hair. And yes, there were many ridiculous memes. We were inclined to give it a chance based on the casting of Momoa and Jack Black. Now the full trailer has dropped, and honestly, odd design choices aside—and they are indeed odd—it looks like a perfectly acceptable fun family film and not much more, albeit very light on actual plot.
As previously reported, once the film went into development, Jared Hess (who worked with star Jack Black on Nacho Libre) ended up directing. The COVID pandemic and 2023 SAG-AFTRA strike delayed things further, but filming finally wrapped earlier this year in Auckland, New Zealand—just in time for a spring 2025 theatrical release. Per the official premise:
Welcome to the world of Minecraft, where creativity doesn’t just help you craft, it’s essential to one’s survival! Four misfits—Garrett “The Garbage Man” Garrison (Jason Momoa), Henry (Sebastian Eugene Hansen), Natalie (Emma Myers) and Dawn (Danielle Brooks)—find themselves struggling with ordinary problems when they are suddenly pulled through a mysterious portal into the Overworld: a bizarre, cubic wonderland that thrives on imagination. To get back home, they’ll have to master this world (and protect it from evil things like Piglins and Zombies, too) while embarking on a magical quest with an unexpected, expert crafter, Steve (Jack Black). Together, their adventure will challenge all five to be bold and to reconnect with the qualities that make each of them uniquely creative… the very skills they need to thrive back in the real world.
Game players will recognize Steve as one of the default characters in Minecraft. The teaser was set to The Beatles’ “Magical Mystery Tour” and showed our misfits encountering a fantastical Tolkien-esque landscape—only with a lot more cube-like shapes, like a pink sheep with a cubed head.
Cracking the recipe for perfect plant-based eggs
Hint: It involves finding exactly the right proteins.
An egg is an amazing thing, culinarily speaking: delicious, nutritious, and versatile. Americans eat nearly 100 billion of them every year, almost 300 per person. But eggs, while greener than other animal food sources, have a bigger environmental footprint than almost any plant food—and industrial egg production raises significant animal welfare issues.
So food scientists, and a few companies, are trying hard to come up with ever-better plant-based egg substitutes. “We’re trying to reverse-engineer an egg,” says David Julian McClements, a food scientist at the University of Massachusetts Amherst.
That’s not easy, because real eggs play so many roles in the kitchen. You can use beaten eggs to bind breadcrumbs in a coating, or to hold together meatballs; you can use them to emulsify oil and water into mayonnaise, scramble them into an omelet or whip them to loft a meringue or angel food cake. An all-purpose egg substitute must do all those things acceptably well, while also yielding the familiar texture and—perhaps—flavor of real eggs.
