Study: Cuttlefish adapt camouflage displays when hunting prey

Crafty cuttlefish employ several different camouflaging displays while hunting their prey, according to a new paper published in the journal Ecology, including mimicking benign ocean objects like a leaf or coral, or flashing dark stripes down their bodies. And individual cuttlefish seem to choose different preferred hunting displays for different environments.

It’s well-known that cuttlefish and several other cephalopods can rapidly shift the colors in their skin thanks to that skin’s unique structure. As previously reported, squid skin is translucent and features an outer layer of pigment cells called chromatophores that control light absorption. Each chromatophore is attached to muscle fibers that line the skin’s surface, and those fibers, in turn, are connected to a nerve fiber. It’s a simple matter to stimulate those nerves with electrical pulses, causing the muscles to contract. And because the muscles are pulling in different directions, the cell expands, along with the pigmented areas, changing the color. When the cell shrinks, so do the pigmented areas.

Underneath the chromatophores, there is a separate layer of iridophores. Unlike the chromatophores, the iridophores aren’t pigment-based but are an example of structural color, similar to the crystals in the wings of a butterfly, except a squid’s iridophores are dynamic rather than static. They can be tuned to reflect different wavelengths of light. A 2012 paper suggested that this dynamically tunable structural color of the iridophores is linked to a neurotransmitter called acetylcholine. The two layers work together to generate the unique optical properties of squid skin.

ChatGPT reaches 400M weekly active users

ChatGPT has surpassed 400 million weekly active users. “We feel very fortunate to serve 5 percent of the world every week,” OpenAI COO Brad Lightcap said on X about the new audience stat. This figure is twice the weekly active user count reported by the company in August 2024, which was double the figure it posted in November 2023.

The latest milestone for the AI assistant comes after a huge uproar over new rival platform DeepSeek earlier in the year, which raised questions about whether the current crop of leading AI tools was about to be dethroned. OpenAI is on the verge of a move to simplify its ChatGPT offerings so that users won’t have to select which reasoning model will respond to an input, and it will make its GPT-4.5 and GPT-5 models available soon in the chat and API clients. With GPT-5 being made available to OpenAI’s free users, ChatGPT seems primed to continue expanding its audience base in the coming months.

ISP sued by record labels agrees to identify 100 users accused of piracy

Cable company Altice agreed to give Warner and other record labels the names and contact information of 100 broadband subscribers who were accused of pirating songs.

The subscribers “were the subject of RIAA or third party copyright notices,” said a court order that approved the agreement between Altice and the plaintiff record companies. Altice is notifying each subscriber “of Altice’s intent to disclose their name and contact information to Plaintiffs pursuant to this Order,” and telling the notified subscribers that they have 30 days to seek relief from the court.

If subscribers do not object within a month, Altice must disclose the subscribers’ names, phone numbers, addresses, and email addresses. The judge’s order was issued on February 12 and reported yesterday by TorrentFreak.

SpaceX engineers brought on at FAA after probationary employees were fired

Engineers who work for Elon Musk’s SpaceX have been brought on as senior advisers to the acting administrator of the Federal Aviation Administration (FAA), sources tell WIRED.

On Sunday, Sean Duffy, secretary of the Department of Transportation, which oversees the FAA, announced in a post on X that SpaceX engineers would be visiting the Air Traffic Control System Command Center in Virginia to take what he positioned as a tour. “The safety of air travel is a nonpartisan matter,” Musk replied. “SpaceX engineers will help make air travel safer.”

By the time these posts were made, though, according to sources who were granted anonymity because they fear retaliation, SpaceX engineers were already being onboarded at the agency under Schedule A, a special authority that allows government managers to “hire persons with disabilities without requiring them to compete for the job,” according to the Office of Personnel Management (OPM).

A $599 iPhone 16e is a cruel joke

The $599 iPhone 16e is many things, but don’t you dare call it a budget phone. I hesitate to even call it “cheap.” As a successor to the $429 iPhone SE, it’s hard not to see the 16e as a disappointment. Sure, it’s $200 less than the vanilla iPhone 16 (which I argued was a great deal at launch), and the 16e also packs in the latest A18 chip with support for Apple Intelligence. But it’s no longer a small phone, and it pushes Apple’s cheaper iPhone option well beyond $500. That’s something we’ll likely never see again. (And it’s potentially terrible news for future iPhone pricing, as well.)

Given the sheer amount of new hardware in the iPhone 16e — including a larger 6.1-inch OLED screen, Apple’s first in-house “C1” modem and that aforementioned A18 chip — it’s easy to make excuses for the price. The 16e is certainly far closer in specs to the iPhone 16 than the third-gen SE was to the iPhone 13. But I’d argue that Apple didn’t exactly need an OLED screen for this model, and there are likely other ways to cut down costs. (It’s even stranger Apple kept out MagSafe and fast wireless charging, which would have been cheaper to implement, and arguably more useful, than a large OLED display.)

Apple

And while it’s nice to have the A18 chip (albeit with one less GPU core) and full Apple Intelligence support, I agree with my colleague Igor Bonifacic that users aren’t exactly clamoring for those AI features. If we had to blame one culprit for the iPhone 16e’s pricing, though, it’s likely Apple Intelligence. After all, Apple is still fighting to prove it isn’t too far behind Microsoft, Google and OpenAI. In any other year, Apple might have been able to justify throwing an older chip in the 16e, but that’s not possible when it’s in the middle of an AI hype war.

Mostly, I’m just sad that Apple is once again raising the price of admission to its walled garden without much justification. There’s something special — noble, even — about sub-$500 smartphones. They’re a reminder of a saner era of smartphones, when prices were being driven down by phones like the Moto G. These days you’re left with Android phones like the Pixel 8a (and potentially the upcoming Pixel 9a), as well as the $400 Samsung Galaxy A35 and $499 Galaxy A55.

Apple

Now that the dream of a sub-$500 iPhone is well and truly dead, it feels like Apple is just setting the stage for future price jumps. A $600 or $650 iPhone 17e will certainly look like a deal compared to a $850 or $900 iPhone 17. And just wait for the inevitable $2,000 iPhone foldable, which could potentially be specced beyond $3,000. 

Of course, you could be a smart Apple shopper and opt for used or refurbished iPhones. I recently picked up a refurbished iPhone 14 Plus as an early Mothers’ Day gift for $420, and Amazon currently has listings for iPhone 14 Pros right under $500. Those devices won’t support Apple Intelligence, but I’d argue sticking to the used market is simply a more useful form of intelligence.

Meta claims torrenting pirated books isn’t illegal without proof of seeding

Just because Meta admitted to torrenting a dataset of pirated books for AI training purposes, that doesn’t necessarily mean that Meta seeded the file after downloading it, the social media company claimed in a court filing this week.

Evidence instead shows that Meta “took precautions not to ‘seed’ any downloaded files,” Meta’s filing said. Seeding refers to sharing a torrented file after the download completes, and because there’s allegedly no proof of such “seeding,” Meta insisted that authors cannot prove Meta shared the pirated books with anyone during the torrenting process.

Whether or not Meta actually seeded the pirated books could make a difference in a copyright lawsuit from book authors including Richard Kadrey, Sarah Silverman, and Ta-Nehisi Coates. Authors had previously alleged that Meta unlawfully copied and distributed their works through AI outputs—an increasingly common complaint that so far has barely been litigated. But Meta’s admission to torrenting appears to add a more straightforward claim of unlawful distribution of copyrighted works through illegal torrenting, which has long been considered established case-law.

FTC Launches Broad Tech ‘Censorship’ Probe Targeting Meta, Uber

The U.S. Federal Trade Commission has launched an inquiry into potential “censorship” by technology platforms ranging from Meta to Uber, marking an escalation in scrutiny of content moderation practices. FTC Chair Andrew Ferguson called for public comment on what he termed “Big Tech censorship,” describing it as “un-American” and “potentially illegal.”

The broad probe could examine social media, video sharing, ride-sharing and event planning services. The announcement follows long-standing Republican claims that conservative viewpoints face discrimination on social media platforms.

Among Us VR is being transformed into a traditional 3D game for PC

Among Us VR has proven itself to be a major hit since first being released back in 2022. Now, developers Innersloth and Schell Games have announced they are rejiggering the virtual reality title for traditional PC players. Among Us 3D is playable without a headset and will be available via Steam in the near future.

This title keeps the core gameplay loop from the original, but shifts to a first-person perspective. It’s basically a new way to keep sabotaging your friends and family. Among Us 3D is for four to ten players and includes native proximity voice chat, with no need for a third-party platform. All of the minigames are returning, though there’s also some new ones coming down the pike. Innersloth is holding off on those details for now.

It features crossplay with Among Us VR, but not with the original game. That’s a bummer, but understandable. There will be, however, an expanded costume selection to offer “an endless number of cosmetic customization combinations.” There’s a new in-game currency called Stardust that will, presumably, be used to purchase some of those outfits.

There’s no release date yet, other than “soon.” However, a demo will be available to US players as part of Steam Next Fest from February 24 to March 3. Preorders for the full game are already live on Steam.

This is just the latest cool thing that developer Innersloth has announced. The company recently revealed a publishing arm called Outersloth. There’s also an Among Us cartoon coming sometime in the near future.

Small study suggests dark mode doesn’t save much power for very human reasons

If you know how OLED displays work, you know about one of their greatest strengths: Individual pixels can be shut off, offering deeper blacks and power savings. Dark modes, now available on most operating systems, aim to save power by making most backgrounds very dark or black, while also gratifying those who just prefer the look.

But what about on the older but still dominant screen technology, LCDs? The BBC is out with a small, interesting study comparing the light and dark modes of one of its website pages on an older laptop. Faced with a dark mode version, most people turned up the brightness a notable amount, sometimes drawing more power than on light mode.

It’s not a surprise that dark modes don’t do anything to reduce LCD power draw. However, the study—not peer-reviewed but published as part of the International Workshop on Low Carbon Computing—suggests that claims about dark mode’s efficiency may be overstated in real-world scenarios, with non-cutting-edge hardware and humans at the controls.

How to make the most of the iPhone’s Action Button

The Action button is available on nearly every iPhone Apple sells, offering a quick way to access a feature, app or shortcut on your phone, just by pushing a button. It can be a flashlight, activate a smart home routine or let you access any number of custom shortcuts without having to unlock your phone and pick through apps.

Apple added the Action Button on the iPhone 15 Pro as a replacement for the iPhone’s original Ring / Silent switch, and it was an acknowledgement of sorts that lots of people keep their phones on silent anyway. Having a reassignable button was pitched as a “Pro” feature at the time, but much like the Dynamic Island, it came to all of Apple’s other phones in short order, even the entry-level iPhone 16e.

Apple

You can use the Action Button for yourself on an iPhone 15 Pro, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max and iPhone 16e just by pressing or holding down the small button above the volume up and down buttons on the left side of your phone. By default, the Action Button will mute or unmute your text and ringtones. This fills the same role as the old Ring / Silent switch. Heading into the Settings app will let you reassign it to another task and you can silence your phone via the Control Center.

Ian Carlos Campbell for Engadget

Out of the box, Apple lets you assign the Action button to several different controls: Silent Mode (Ring / Silent), Focus (either a specific Focus or a menu that lets you pick each time), Camera (a specific mode like Photo or Video), Flashlight, Voice Memo, Recognize Music, Translate, Magnifier, Controls (a specific control from Control Center like Airplane Mode), Shortcut, Accessibility (toggling a specific accessibility feature) or do nothing at all.

If you wanted to switch from the default, Silent Mode, to the Flashlight, you need to first unlock your phone. Then: 

  1. Open the Settings app. 

  2. Tap on “Action Button.” 

  3. From there, swipe through the different options until you land on Flashlight.  

  4. To test that it worked, try pressing on the Action Button.

You can use this same process to reassign the Action Button to any of the built-in actions Apple provides.

Ian Carlos Campbell for Engadget

If you’d like to get a little more adventurous, you can also have the Action Button open a specific app on your phone. Let’s say, for example, your go-to game on the iPhone is Balatro. You can have the Action Button automatically pull up Balatro whenever you press it.

To set it up, you’ll need your iPhone unlocked.

  1. Open the Settings app.

  2. Tap on “Action Button.”

  3. Swipe through the options until you reach “Shortcut.”

  4. Tap on “Choose a Shortcut…”

  5. Then tap on “Open App…”

  6. Then scroll until you find your chosen app and tap on it.

This process works for any app on your phone, including features of specific apps, like if you wanted to jump directly into ChatGPT’s Voice Mode or a new note in the Notes app.

Ian Carlos Campbell for Engadget

The Shortcut action works for more complicated Apple Shortcuts, too. Technically, any shortcut designed to be triggered by you choosing to activate it (as opposed to a time or location-based shortcut) works. There’s a lot of interesting shortcuts out there, and plenty of custom ones you can make on your own, but to use a simple example, here’s how you’d set the Action Button to start a Pomodoro timer.

  1. Open the Settings app.

  2. Tap on “Action Button.”

  3. Swipe through the options until you get to “Shortcut.”

  4. Tap on “Choose a Shortcut…”

  5. Tap on whatever shortcut you want activate.

  6. Press and hold the Action Button to make sure it works.

In the case of the Pomodoro timer, you’ll be prompted to choose how long you want the timer to last, and then you can tap “Done” to start it.

Between lock screen widgets and app shortcuts, home screen widgets, and the Action Button, there’s now multiple ways to check information inside of an app, adjust a specific setting or use specific functionality from the apps on your iPhone. It’s confusing, but a good rule of thumb is that the Action Button works best for actions that you only need to enable once or binary, on / off features. Plenty of others things work, but at a certain point you’ll want to be spending time in an app instead of futzing with the buttons on your phone.

Twitch is Limiting Streamers To 100 hours of Highlights and Uploads

Twitch is planning to cull some of the content archived by streamers to save on storage costs. From a report: On Wednesday the streaming platform announced that it will introduce a 100-hour storage cap for Highlights and Uploads starting April 19th, warning that users will have their content automatically deleted until it falls below the limit.

Twitch says it’s doing this because “Highlights haven’t been very effective in driving discovery or engagement,” and it isn’t worth the cost of storing thousands of hours of such content. Twitch is owned by Amazon, a market-leading cloud storage provider — a detail that hasn’t gone unnoticed by streamers criticizing the decision.

Amazon is shutting down its third-party Android app store

The Amazon Appstore will no longer be available on Android as of August 20, 2025. After that date, apps from the digital storefront “are not guaranteed to operate” on Android hardware; however, they can continue to be used on devices like the Fire TV and Fire Tablets. The Coins program, Amazon’s virtual currency for some Appstore app and in-app purchases, will also end on that same date. Coins will no longer be available for purchase beginning today.

The Appstore was Amazon’s effort to get in on the app distribution game for Android. Third-party app stores have been a hot topic for the business world in recent years, with the owners of walled gardens insisting that everything is fair while the companies trying to get a share of the action for themselves insist that it’s not. There have been mixed moves to address the question in the US government, while regions such as the EU have taken more decisive steps to increase competition.

Apple, Lenovo lead losers in laptop repairability analysis

Apple and Lenovo had the lowest laptop repairability scores in an analysis of recently released devices from consumer advocacy group US Public Interest Research Group (PIRG) Education Fund. While Apple’s low marks are partially due the difficulty involved in disassembling MacBooks, Lenovo appears to be withholding information from shoppers deemed critical to right-to-repair legislation and accessibility.

The report, US PIRG’s fourth annual “Failing the Fix” [PDF], calculated repairability scores for PCs and smartphones from popular brands in the US. The report examines “the top 10 most recent devices from each brand that were available for sale directly from manufacturers in January 2025.” If a brand’s website didn’t allow people to sort by newest release, US PIRG picked devices by sorting “by ‘Bestselling’ or something similar,” per the report’s methodology section.

US PIRG’s analysis included finding each device’s French Repairability Index scores on PC makers’ French websites and on third-party retailer sites. US PIRG calculated PC makers’ grades by averaging “the total French score and the isolated disassembly score from each device.” It weighed disassembly scores more heavily because it believes “this better reflects what consumers think a repairability score indicates.” Next, the group subtracted half a point each for membership in TechNet or the Consumer Technology Association (CTA), industry groups that oppose right-to-repair legislation, and added a quarter point “for each piece of Right to Repair legislation supported by the testimony of the manufacturer in the last year.”
