Megafauna was the meat of choice for South American hunters

And that makes perfect sense, because when you reduce hunters’ choices to simple math using what’s called the prey choice model (more on that below), these long-lost species offered bigger returns for the effort of hunting. In other words, giant sloths are extinct because they were delicious and made of meat.

Yup, it’s humanity’s fault—again

As the last Ice Age drew to a close, the large animals that had once dominated the world’s chilly Pleistocene landscapes started to vanish. Mammoths, saber-toothed tigers, and giant armadillos died out altogether. Other species went locally extinct; rhinoceroses no longer stomped around southern Europe, and horses disappeared from the Americas until European colonists brought new species with them thousands of years later.

Scientists have been arguing about how much of that was humanity’s fault for quite a while.

Most of the blame goes to the world’s changing climate; habitats shifted as the world mostly got warmer and wetter. But, at least in some places, humans may have sped the process along, either by hunting the last of the Pleistocene megafauna to extinction or just by shaking up the rest of the ecosystem so much that it was all too ready to collapse, taking the biggest species down with it.

It looks, at first glance, like South America’s late Ice Age hunters are safely not guilty. For one thing, the megafauna didn’t start dying out until thousands of years after humans first set foot in the region. Archaeologists also haven’t found many sites that contain both traces of human activity and the bones of extinct horses, giant armadillos, or other megafauna. And at those few sites, megafauna bones made up only a small percentage of the contents of ancient scrap piles. Not enough evidence places us at the crime scene, in other words—or so it seems.

On the other hand, the Ice Age megafauna began dying out in South America around 13,000 years ago, roughly the same time that a type of projectile point called the fishtail appeared. That may not be a coincidence, argued one study. And late last year, another study showed that farther north, in what’s now the United States, Clovis people’s diets contained mammoth amounts of… well, mammoth.

OpenAI mocks Musk’s math in suit over iPhone/ChatGPT integration

“Fraction of a fraction of a fraction”

xAI’s claim that Apple gave ChatGPT a monopoly on prompts is “baseless,” OpenAI says.

OpenAI and Apple have moved to dismiss a lawsuit by Elon Musk’s xAI, alleging that ChatGPT’s integration into a “handful” of iPhone features violated antitrust laws by giving OpenAI a monopoly on prompts and Apple a new path to block rivals in the smartphone industry.

The lawsuit was filed in August after Musk raged on X about Apple never listing Grok on its editorially curated “Must Have” apps list, which ChatGPT frequently appeared on.

According to Musk, Apple linking ChatGPT to Siri and other native iPhone features gave OpenAI exclusive access to billions of prompts that only OpenAI can use as valuable training data to maintain its dominance in the chatbot market. However, OpenAI and Apple are now mocking Musk’s math in court filings, urging the court to agree that xAI’s lawsuit is doomed.

As OpenAI argued, the estimates in xAI’s complaint seemed “baseless,” with Musk hesitant to even “hazard a guess” at what portion of the chatbot market is being foreclosed by the OpenAI/Apple deal.

xAI suggested that the ChatGPT integration may give OpenAI “up to 55 percent” of the potential chatbot prompts in the market, which could mean anywhere from 0 to 55 percent, OpenAI and Apple noted.

Musk’s company apparently arrived at this vague estimate by doing “back-of-the-envelope math,” and the court should reject his complaint, OpenAI argued. That math “was evidently calculated by assuming that Siri fields ‘1.5 billion user requests per day globally,’ then dividing that quantity by the ‘total prompts for generative AI chatbots in 2024,'”—”apparently 2.7 billion per day,” OpenAI explained.

These estimates “ignore the facts” that “ChatGPT integration is only available on the latest models of iPhones, which allow users to opt into the integration,” OpenAI argued. And for any user who opts in, they must link their ChatGPT account for OpenAI to train on their data, OpenAI said, further restricting the potential prompt pool.

By Musk’s own logic, OpenAI alleged, “the relevant set of Siri prompts thus cannot plausibly be 1.5 billion per day, but is instead an unknown, unpleaded fraction of a fraction of a fraction of that number.”

Additionally, OpenAI mocked Musk for using 2024 statistics, writing that xAI failed to explain “the logic of using a year-old estimate of the number of prompts when the pleadings elsewhere acknowledge that the industry is experiencing ‘exponential growth.'”

Apple’s filing agreed that Musk’s calculations “stretch logic,” appearing “to rest on speculative and implausible assumptions that the agreement gives ChatGPT exclusive access to all Siri requests from all Apple devices (including older models), and that OpenAI may use all such requests to train ChatGPT and achieve scale.”

“Not all Siri requests” result in ChatGPT prompts that OpenAI can train on, Apple noted, “even by users who have enabled devices and opt in.”

OpenAI reminds court of Grok’s MechaHitler scandal

OpenAI argued that Musk’s lawsuit is part of a pattern of harassment that OpenAI previously described as “unrelenting” since ChatGPT’s successful debut, alleging it was “the latest effort by the world’s wealthiest man to stifle competition in the world’s most innovative industry.”

As OpenAI sees it, “Musk’s pretext for litigation this time is that Apple chose to offer ChatGPT as an optional add-on for several built-in applications on its latest iPhones,” without giving Grok the same deal. But OpenAI noted that the integration was rolled out around the same time that Musk removed “woke filters” that caused Grok to declare itself “MechaHitler.” For Apple, it was a business decision to avoid Grok, OpenAI argued.

Apple did not reference the Grok scandal in its filing but in a footnote confirmed that “vetting of partners is particularly important given some of the concerns about generative AI chatbots, including on child safety issues, nonconsensual intimate imagery, and ‘jailbreaking’—feeding input to a chatbot so it ignores its own safety guardrails.”

A similar logic was applied to Apple’s decision not to highlight Grok as a “Must Have” app, their filing said. After Musk’s public rant about Grok’s exclusion on X, “Apple employees explained the objective reasons why Grok was not included on certain lists, and identified app improvements,” Apple noted, but instead of making changes, xAI filed the lawsuit.

Also taking time to point out the obvious, Apple argued that Musk was fixated on the fact that his charting apps never make the “Must Have Apps” list, suggesting that Apple’s picks should always mirror “Top Charts,” which tracks popular downloads.

“That assumes that the Apple-curated Must-Have Apps List must be distorted if it does not strictly parrot App Store Top Charts,” Apple argued. “But that assumption is illogical: there would be little point in maintaining a Must-Have Apps List if all it did was restate what Top Charts say, rather than offer Apple’s editorial recommendations to users.”

Likely most relevant to the antitrust charges, Apple accused Musk of improperly arguing that “Apple cannot partner with OpenAI to create an innovative feature for iPhone users without simultaneously partnering with every other generative AI chatbot—regardless of quality, privacy or safety considerations, technical feasibility, stage of development, or commercial terms.”

“No facts plausibly” support xAI’s “assertion that Apple intentionally ‘deprioritized'” xAI apps “as part of an illegal conspiracy or monopolization scheme,” Apple argued.

And most glaringly, Apple noted that xAI is not a rival or consumer in the smartphone industry, where it alleges competition is being harmed. Apple urged the court to reject Musk’s theory that Apple is incentivized to boost OpenAI to prevent xAI’s ascent in building a “super app” that would render smartphones obsolete. If Musk’s super app dream is even possible, Apple argued, it’s at least a decade off, insisting that as-yet-undeveloped apps should not serve as the basis for blocking Apple’s measured plan to better serve customers with sophisticated chatbot integration.

“Antitrust laws do not require that, and for good reason: imposing such a rule on businesses would slow innovation, reduce quality, and increase costs, all ultimately harming the very consumers the antitrust laws are meant to protect,” Apple argued.

Musk’s weird smartphone market claim, explained

Apple alleged that Musk’s “grievance” can be “reduced to displeasure that Apple has not yet ‘integrated with any other generative AI chatbots’ beyond ChatGPT, such as those created by xAI, Google, and Anthropic.”

In a footnote, the smartphone giant noted that by xAI’s logic, Musk’s social media platform X “may be required to integrate all other chatbots—including ChatGPT—on its own social media platform.”

But antitrust law doesn’t work that way, Apple argued, urging the court to reject xAI’s claims of alleged market harms that “rely on a multi-step chain of speculation on top of speculation.” As Apple summarized, xAI contends that “if Apple never integrated ChatGPT,” xAI could win in both chatbot and smartphone markets, but only if:

1. Consumers would choose to send additional prompts to Grok (rather than other generative AI chatbots).

2. The additional prompts would result in Grok achieving scale and quality it could not otherwise achieve.

3. As a result, the X app would grow in popularity because it is integrated with Grok.

4. X and xAI would therefore be better positioned to build so-called “super apps” in the future, which the complaint defines as “multi-functional” apps that offer “social connectivity and messaging, financial services, e-commerce, and entertainment.”

5. Once developed, consumers might choose to use X’s “super app” for various functions.

6. “Super apps” would replace much of the functionality of smartphones and consumers would care less about the quality of their physical phones and rely instead on these hypothetical “super apps.”

7. Smartphone manufacturers would respond by offering more basic models of smartphones with less functionality.

8. iPhone users would decide to replace their iPhones with more “basic smartphones” with “super apps.”

Apple insisted that nothing in its OpenAI deal prevents Musk from building his super apps, while noting that from integrating Grok into X, Musk understands that integration of a single chatbot is a “major undertaking” that requires “substantial investment.” That “concession” alone “underscores the massive resources Apple would need to devote to integrating every AI chatbot into Apple Intelligence,” while navigating potential user safety risks.

The iPhone maker also reminded the court that it has always planned to integrate other chatbots into its native features after investing in and testing Apple Intelligence’s performance, relying on what Apple deems is the best chatbot on the market today.

Backing Apple up, OpenAI noted that Musk’s complaint seemed to cherry-pick testimony from Google CEO Sundar Pichai, claiming that “Google could not reach an agreement to integrate” Gemini “with Apple because Apple had decided to integrate ChatGPT.”

“The full testimony recorded in open court reveals Mr. Pichai attesting to his understanding that ‘Apple plans to expand to other providers for Generative AI distribution’ and that ‘[a]s CEO of Google, [he is] hoping to execute a Gemini distribution agreement with Apple’ later in 2025,” OpenAI argued.

Hyundai gives the Ioniq 5 a huge price cut for model-year 2026

Cars, Hyundai Ioniq 5 / Beth Washington / October 2, 2025

Earlier today, we wrote about how Ford, General Motors, and Tesla have reacted to the end of the clean vehicle tax credits. Now we know what Hyundai is doing, and the answer is “giving the Ioniq 5 a huge price cut.”

The cheapest Ioniq 5 is still the SE RWD. A model-year 2025 SE RWD cost $42,600; for model-year 2026 it’s now $35,000. The price cuts for other versions are even greater—between $9,150 and $9,800. For example, the Ioniq 5 XRT that you see in the photo above had a starting price of $55,500 for MY25; now it starts at a very reasonable $46,275.

“Hyundai is taking bold steps to ensure our award-winning Ioniq 5 remains a top choice for EV buyers,” said Randy Parker, president and CEO of Hyundai Motor North America. “This pricing realignment reflects our commitment to delivering exceptional technology and innovation without compromise.”

Unlike the tax credit, there’s no income cap applied to Hyundai’s price cut. But the cuts have only been applied to Ioniq 5s built in the US—the Ioniq 5 N, built in Korea, was absent from Hyundai’s press release, as was the Ioniq 6 sedan or the Ioniq 9 three-row SUV. However, Hyundai said that those MY25 cars are still eligible for a manufacturer’s incentive of $7,500.

Hyundai updated the Ioniq 5 last year, adding native NACS ports and other improvements to an already-excellent EV, like adding the missing rear windshield wiper.

Cable nostalgia persists as streaming gets more expensive, fragmented

cable, streaming, Tech / Beth Washington / October 2, 2025

Streaming is overtaking broadcast, cable, and satellite. But amid all the cord cutting lies a much smaller, yet intriguing, practice: going back to cable.

Cord reviving is when cord cutters, or people who previously abandoned traditional TV services in favor of streaming, decide to go back to traditional pay-TV services, like cable.

There’s no doubt that this happens far less frequently than cord cutting. But TiVo’s Q2 2025 Video Trends Report: North America released today points to growth in cord reviving. It reads:

The share of respondents who cut the cord but later decided to resubscribe to a traditional TV service has increased about 10 percent, to 31.9 percent in Q2 2025.

TiVo’s report is based on a survey conducted by an unspecified third-party survey service in Q2 2025. The respondents are 4,510 people who are at least 18 years old and living in the US or Canada, and the survey defines traditional TV services as pay-TV platforms offering linear television via cable, satellite, or managed IPTV platforms.

It’s important to note that TiVo is far from an impartial observer. In addition to selling an IPTV platform, its parent company, Xperi, works with cable, broadband, and pay-TV providers and would directly benefit from the existence or perception of a cord reviving “trend.”

This isn’t the first time we’ve heard of streaming customers returning to cable. Surveys of 3,055 US adults in 2013 and 2025 by CouponCabin found that “among those who have made the switch from cable to streaming, 22 percent have returned to cable, while another 6 percent are considering making the switch back.”

When reached for comment, a TiVo spokesperson said via email that cord reviving is driven by a “mixture of reasons, with internet bundle costs, familiarity of use, and local content (sports, news, etc.) being the primary drivers.” The rep noted that it’s “likely” that those re-subscribing to traditional TV services are using them alongside some streaming subscriptions.

“It’s possible that users are churning off some [streaming] services where there is overlap with traditional TV services,” TiVo’s spokesperson said.

Cable nostalgia

According to Nielsen, streaming service viewership on TVs surpassed that of cable and broadcast combined for the first time in May (44.8 percent for streaming versus 24.1 percent for cable and 20.1 percent for broadcast).

Trailer for del Toro’s Frankenstein is pure macabre mythology

culture, film trailers, frankenstein, Guillermo del Toro, netflix, Trailers / Beth Washington / October 1, 2025

Per the official synopsis:

Oscar-winning director Guillermo del Toro adapts Mary Shelley’s classic tale of Victor Frankenstein, a brilliant but egotistical scientist who brings a creature to life in a monstrous experiment that ultimately leads to the undoing of both the creator and his tragic creation.

In addition to Isaac, the cast includes Jacob Elordi as the Creature; Mia Goth as Elizabeth Lavenza, who is engaged to Victor’s young brother William, played by William Kammerer; Lars Mikkelsen as Captain Anderson; Christoph Waltz as Heinrich Harlander, uncle to Elizabeth and wealthy financer of Victor’s experiments; Charles Dance as Victor’s father Leopold; Lauren Collins as Victor’s late mother Claire; David Bradley as the blind man; Sofia Galasso as the little girl; Ralph Ineson as Professor Krempe; and Burn Gorman as Fritz.

The trailer looks every bit as mythically epic and visually lavish as del Toro said he wanted for his version. “I remember pieces, the Creature says in a voiceover as footage plays out. “Memories of different men. Then I saw it. Your name. Victor Frankenstein. My creator. I demand a single grace from you. If you are not to award me love, then I will indulge in rage.”

We see lavish balls, Victor’s Gothic laboratory, a ship trapped in Arctic ice, and lots and lots of consuming fire—everything one could want in a Frankenstein movie from a master of macabre mythologies.

Frankenstein hits theaters on October 17, 2025. It will start streaming on Netflix on November 7.

Taiwan rejects Trump’s demand to shift 50% of chip manufacturing into US

Policy, Taiwan, Taiwan Semiconductor Manufacturing Company, trump tariffs / Beth Washington / October 1, 2025

In August, Trump claimed that chip tariffs could be as high as 100 percent while promising to exempt any tech companies that have committed to moving significantly more manufacturing into the US.

Since then, sources familiar with the investigation told Reuters that “the Trump administration is considering imposing tariffs on foreign electronic devices based on the number of chips in each one.” Under that potential plan, the tariff charged would be “equal to a percentage of the estimated value of the product’s chip content,” sources suggested.

Some expect that companies like the Taiwan Semiconductor Manufacturing Company (TSMC) may be exempted from these tariffs, based on a pledge to invest $100 billion into US chip manufacturing.

However, sources told Reuters that the Commerce Department has weighed offering “a dollar-for-dollar exemption based on investment in US-based manufacturing only if a company moves half its production to the US.” TSMC’s total market value is more than $1 trillion, so the US may seek more investments if the campaign to move half of Taiwan’s chip production into the US fails.

Brzytwa told Ars that tech companies are already struggling to do the math from Trump’s tariff stacking. And those headaches will likely continue. At a meeting last week with chip industry executives, Lutnick confirmed that Trump plans to use tariffs to push tech companies to buy US-made chips, The New York Times reported.

If those plans go through, companies would be expected to buy half their chips in the US, earning credits “for each dollar spent on American semiconductors, which they can use against what they spend on foreign semiconductors,” the Times reported.

Any company not maintaining “a 1:1 ratio over time would have to pay a tariff,” sources told The Wall Street Journal. For companies like Apple, the policy would require tracking every chip used in every device to ensure a perfect match. But there would likely be an initial grace period, allowing companies to adjust to the new policy as the US increases its domestic chip supply chain, the WSJ reported. And chipmakers like TSMC could potentially benefit, the WSJ reported, possibly gaining leverage in the market if it increases its US manufacturing ahead of rivals.

Google’s Gemini-powered smart home revamp is here with a new app and cameras

Google promises a better smart home experience thanks to Gemini.

Google’s products and services have been flooded with AI features over the past couple of years, but smart home has been largely spared until now. The company’s plans to replace Assistant are moving forward with a big Google Home reset. We’ve been told over and over that generative AI will do incredible things when given enough data, and here’s the test.

There’s a new Home app with Gemini intelligence throughout the experience, updated subscriptions, and even some new hardware. The revamped Home app will allegedly gain deeper insights into what happens in your home, unlocking advanced video features and conversational commands. It demos well, but will it make smart home tech less or more frustrating?

A new Home

You may have already seen some elements of the revamped Home experience percolating to the surface, but that process begins in earnest today. The new app apparently boosts speed and reliability considerably, with camera feeds loading 70 percent faster and with 80 percent fewer app crashes. The app will also bring new Gemini features, some of which are free. Google’s new Home subscription retains the same price as the old Nest subs, but naturally, there’s a lot more AI.

Google claims that Gemini will make your smart home easier to monitor and manage. All that video streaming from your cameras churns through the AI, which interprets the goings on. As a result, you get features like AI-enhanced notifications that give you more context about what your cameras saw. For instance, your notifications will include descriptions of activity, and Home Brief will summarize everything that happens each day.

Conversational interaction is also a big part of this update. In the home app, subscribers will see a new Ask Home bar where you can input natural language queries. For example, you could ask if a certain person has left or returned home, or whether or not your package showed up. At least, that’s what’s supposed to happen—generative AI can get things wrong.

The new app comes with new subscriptions based around AI, but the tiers don’t cost any more than the old Nest plans, and they include all the same video features. The base $10 subscription, now known as Standard, includes 30 days of video event history, along with Gemini automation features and the “intelligent alerts” Home has used for a while that can alert you to packages, familiar faces, and so on. The $20 subscription is becoming Home Advanced, which adds the conversational Ask Home feature in the app, AI notifications, AI event descriptions, and a new “Home Brief.” It also still offers 60 days of events and 10 days of 24/7 video history.

Free users still get saved event video history, and it’s been boosted from three hours to six. If you are not subscribing to Gemini Home or using the $10 plan, the Ask Home bar that is persistent across the app will become a quick search, which surfaces devices and settings.

If you’re already subscribing to Google’s AI services, this change could actually save you some cash. Anyone with Google AI Pro (a $20 sub) will get Home Standard for free. If you’re paying for the lavish $250 per month AI Ultra plan, you get Home Advanced at no additional cost.

A proving ground for AI

You may have gotten used to Assistant over the past decade in spite of its frequent feature gaps, but you’ll have to leave it behind. Gemini for Home will be taking over beginning this month in early access. The full release will come later, but Google intends to deliver the Gemini-powered smart home experience to as many users as possible.

Gemini will replace Assistant on every first-party Google Home device, going all the way back to the original 2016 Google Home. You’ll be able to have live chats with Gemini via your smart speakers and make more complex smart home queries. Google is making some big claims about contextual understanding here.

If you’ve used Gemini Live, the new Home interactions will seem familiar. You can ask Gemini anything you want via your smart speakers, perhaps getting help with a recipe or an appliance issue. However, the robot will sometimes just keep talking long past the point it’s helpful. Like Gemini Live, you just have to interrupt the robot sometimes. Google also promises a selection of improved voices to interrupt.

If you want to get early access to the new Gemini Home features, you can sign up in the Home app settings. Just look for the “Early access” option. Google doesn’t guarantee access on a specific timeline, but the first people will be allowed to try the new Gemini Home this month.

New AI-first hardware

It has been four years since Google released new smart home devices, but the era of Gemini brings some new hardware. There are three new cameras, all with 2K image sensors. The new Nest Indoor camera will retail for $100, and the Nest Outdoor Camera will cost $150 (or $250 in a two-pack). There’s also a new Nest Doorbell, which requires a wired connection, for $180.

Google says these cameras were designed with generative AI in mind. The sensor choice allows for good detail even if you need to digitally zoom in, but the video feed is still small enough to be ingested by Google’s AI models as it’s created. This is what gives the new Home app the ability to provide rich updates on your smart home.

You may also notice there are no battery-powered models in the new batch. Again, that’s because of AI. A battery-powered camera wakes up only momentarily when the system logs an event, but this approach isn’t as useful for generative AI. Providing the model with an ongoing video stream gives it better insights into the scene and, theoretically, produces better insights for the user.

All the new cameras are available for order today, but Google has one more device queued up for a later release. The “Google Home Speaker” is Google’s first smart speaker release since 2020’s Nest Audio. This device is smaller than the Nest Audio but larger than the Nest Mini speakers. It supports 260-degree audio with custom on-device processing that reportedly makes conversing with Gemini smoother. It can also be paired with the Google TV Streamer for home theater audio. It will be available this coming spring for $99.

Google Home will continue to support a wide range of devices, but most of them won’t connect to all the advanced Gemini AI features. However, that could change. Google has also announced a new program for partners to build devices that work with Gemini alongside the Nest cameras. Devices built with the new Google Camera embedded SDK will begin appearing in the coming months, but Walmart’s Onn brand has two ready to go. The Onn Indoor camera retails for $22.96 and the Onn Video Doorbell is $49.86. Both cameras are 1080p resolution and will talk to Gemini just like Google’s cameras. So you may have more options to experience Google’s vision for the AI home of the future.

The most efficient Crosstrek ever? Subaru’s hybrid gets a bit rugged.

car review, Cars, First drive, Subaru Crosstrek Hybrid / Beth Washington / September 30, 2025

MG2 then sits at the rear of the CVT, linked via a planetary gearset, and working in concert with the gasoline engine to power the wheels. Alone, MG2 can also manage a minimal mile or so of EV-only range at a max of 19 mph (30.5 km/h)—but more importantly, boosts total low-end torque and high-end horsepower, as well as handling regenerative braking. (We’re still waiting on the exact horsepower contribution and will update this when we hear back from Subaru.)

It might be a boxer, but it’s no heavyweight

The Atkinson 2.5 L puts out just 162 hp (119 kW) and 154 lb-ft (209 Nm) of torque on its own, but MG2 contributes enough juice for combined system rating peaks of 194 hp (143 kW). That’s an improvement of 14 hp versus the ICE-only (non-Atkinson) 2.5 L Boxer’s 180 hp (and 178 lb-ft). Those numbers might still seem paltry compared to so many other automakers in the modern era, which responded to governmental regulations by hybridizing ever bigger and heavier cars to make them more powerful rather than necessarily more efficient—BMW’s gargantuan M5 stands out as a recent offender. Not so for Crosstrek, which still tips the scales at a relatively svelte 3,662 pounds (1,661 kg), further contributing to efficiency while accelerating.

There’s a horizontally opposed boxer engine under there. And the orange HV cables are a clue there’s a hybrid system, too. Michael Teo Van Runkle

The new Crosstrek Hybrid only manages insignificant weight savings compared to 3,717 lbs (1,686 kg) for the previous plug-in, which boasted 17 miles (27 km) of all-electric range. But that generation therefore sacrificed trunk space to house a much larger 8.8-kWh lithium-ion battery. Dual motors and the smaller battery pack do contribute to a 400-pound (181-kg) gain versus the equivalent non-hybrid variant of the current generation, though. Yet in addition to the power improvements, fuel economy jumps up to EPA ratings of 36 mpg (6.5.L//100 km) city, 36 highway, and (therefore) 36 combined—38 percent better than the ICE Crosstrek, according to Subaru.

In back-to-back drives through the forested hills of northern Oregon and southern Washington, punching the go pedal in a Crosstrek Hybrid brings on a much more potent rush of throttle response and acceleration, far outpacing the naturally aspirated engine. The constant-velocity transmission simulates shifts despite effectively holding the hybrid system in its happy place, and the sound of MG2 working produces a fun little whine, almost like a turbocharger. All while the Symmetrical AWD system smoothly and predictably meters traction out to each wheel in quintessential Subaru fashion.

Scientists unlock secret to Venus flytrap’s hair-trigger response

botany, carnivorous plants, Science, venus flytrap / Beth Washington / September 30, 2025

To trap its prey, the Venus flytrap sends rapid electrical impulses, which are generated in response to touch or stress. But the molecular identity of the touch sensor has remained unclear. Japanese scientists have identified the molecular mechanism that triggers that response and have published their work in a new paper in the journal Nature Communications.

As previously reported, the Venus flytrap attracts its prey with a pleasing fruity scent. When an insect lands on a leaf, it stimulates the highly sensitive trigger hairs that line the leaf. When the pressure becomes strong enough to bend those hairs, the plant will snap its leaves shut and trap the insect inside. Long cilia grab and hold the insect in place, much like fingers, as the plant begins to secrete digestive juices. The insect is digested slowly over five to 12 days, after which the trap reopens, releasing the dried-out husk of the insect into the wind.

In 2016, Rainer Hedrich, a biophysicist at Julius-Maximilians-Universität Würzburg in Bavaria, Germany, led the team that discovered that the Venus flytrap could actually “count” the number of times something touches its hair-lined leaves—an ability that helps the plant distinguish between the presence of prey and a small nut or stone, or even a dead insect. The plant detects the first “action potential” but doesn’t snap shut right away, waiting until a second zap confirms the presence of actual prey, at which point the trap closes. But the Venus flytrap doesn’t close all the way and produce digestive enzymes to consume the prey until the hairs are triggered three more times (for a total of five stimuli).

And in 2023, scientists developed a bioelectronic device to better understand the Venus flytrap’s complex signaling mechanism by mapping how those signals propagate. They confirmed that the electrical signal starts in the plant’s sensory hairs and then spreads radially outward with no clear preferred direction. And sometimes the signals were spontaneous, originating in sensory hairs that had not been stimulated.

Glowing green

This latest research is an outgrowth of a 2020 paper detailing how the Japanese authors genetically altered a Venus flytrap to gain important clues about how the plant’s short-term “memory” works. They introduced a gene for a calcium sensor protein called GCaMP6, which glows green whenever it binds to calcium. That green fluorescence allowed the team to visually track the changes in calcium concentrations in response to stimulating the plant’s sensitive hairs with a needle. They concluded that the waxing and waning of calcium concentrations in the leaf cells seem to serve as a kind of short-term memory for the Venus flytrap, though precisely how calcium concentrations work with the plant’s electrical network remained unclear.

Silver Lake was part of the consortium involved in this month’s controversial deal to bring TikTok under the control of US-based companies. In 2013, the private investment firm also helped take computer-maker Dell private in a $25 billion deal.

Kushner, Affinity Partners’ CEO and the son-in-law of President Trump, said in a statement that he has “admired [EA’s] ability to create iconic, lasting experiences, and as someone who grew up playing their games—and now enjoys them with his kids—I couldn’t be more excited about what’s ahead.”

EA went public with an IPO on the NASDAQ stock exchange in 1990, and by 1996 its market cap had risen to $1.61 billion. Last week, the company’s valuation was hovering around $43 billion.

EA brought in $7.5 billion in revenue in the 2025 fiscal year (ending March 31) on the strength of franchises including Madden NFL, EA Sports FC, Battlefield, The Sims, Dragon Age, and Plants vs. Zombies.

Scientists want to treat complex bone fractures with a bone-healing gun

After examining a few candidate formulations, the team found the right material. “We used a biocompatible thermoplastic called polycaprolactone and hydroxyapatite as base materials,” Lee said. Polycaprolactone was chosen because it is an FDA-approved material that degrades in the body within a few months after implantation. The hydroxyapatite, on the other hand, supports bone-tissue regeneration. Lee’s team experimented with various proportions of these two ingredients and finally nailed the formulation that checked all the boxes: It extruded at a relatively harmless 60° Celsius, the mix was mechanically sound, it adhered to the bone well, and it degraded over time.

Once the bone-healing bullets were ready, the team tested them on rabbits. Rabbits with broken femurs treated with Lee’s healing gun recovered faster than those treated with bone cement, which is the closest commercially available alternative. But there is still a lot to do before the healing gun can be tested on humans.

Skill issues

While the experiment on rabbits revealed new bone tissues forming around the implants created with the healing gun, their slow degradation of the implanted material prevented the full restoration of bone tissues. Another improvement Lee plans involves adding antibiotics to the formulation. The implant, he said, will release the drugs over time to prevent infections.

Then there’s the issue of load bearing. Rabbits are fine as test subjects, but they are rather light. “To evaluate the potential to use this technology on humans, we need to look into its long-term safety in large animal models,” Lee said.

Beyond the questions about the material, the level of skill required to operate this healing gun seems rather high.

Extrusion-based 3D printers, the ones that work more or less like very advanced hot glue guns, usually use guiding rods or rails for precise printing head positioning. If those rods or rails are warped, even slightly, the accuracy of your prints will most likely suffer. Achieving comparable precision with a handheld device might be a bit difficult, even for a skilled surgeon. “It is true that the system requires practice,” Lee said. “We may need to integrate it with a guiding mechanism that would position the head of the device precisely. This could be our next-gen bone printing device.”

Asus’ new ROG Xbox Ally X set to break the bank at $999.99

ASUS, asus rog ally, asus rog ally x, gaming, Portable gaming / Beth Washington / September 26, 2025

Microsoft and Asus revealed the ROG Xbox Ally handheld PC gaming line in June and promised an October 16 launch date in August. But they waited all the way until Thursday night to reveal preorder pricing set at $599.99 for the base ROG Xbox Ally hardware and a whopping $999.99 for the souped-up ROG Xbox Ally X.

Those prices put the baseline ROG Xbox Ally units in the same general price tier as competition like Valve’s Steam Deck OLED, Lenovo’s Legion Go S, and even Nintendo’s Switch 2. But the higher-grade ROG Xbox Ally X is significantly more expensive than almost all competing gaming handhelds, thanks in part to components like a Ryzen Z2 Extreme processor and an NPU that Asus says will ensure it is ready for a future when “AI enhancements” are rolling out in new games.

That may seem like overkill when Steam Deck users seem content using their handheld mainly for low-end games like Vampire Survivors and Hades. But Asus said that, in pre-release hardware tests, the ROG Xbox Ally X gets “up to a 30% performance boost” over 2024’s ROG Ally X on high-end games like Indiana Jones and the Great Circle. The newer hardware also gets “up to twice the battery life” over the ROG Ally X on a game like Hollow Knight Silksong, Asus said.

The new Xbox Ally line keeps the same 7-inch 1080p screens and starting RAM and storage capacity as the regular ROG Ally units from years past. But in addition to upgraded processors, Asus’ new handhelds also sport branded Xbox-style controls and logos and promise easy access to “all of the games available on Windows” through the new “Xbox experience for handhelds” that can handle games from various storefronts and manage launchers.

We’ll have to wait until we get our hands on our own testing units to see how that extra power and new interface compare to the competition. For now, the ROG Xbox Ally can be preordered directly from the Asus shop or retailers like Microsoft and Best Buy.
