Apple does a lot to help us find misplaced iPhones, Apple Watches, and iPads, and rumors strongly suggest that Apple is currently working on a Tile-like device that will allow us to find other items as well. Here’s everything we know so far.The latest rumor: AirTags referenced in Apple support video
Apple isn’t trying too hard to hide the existence of AirTags. In April of 2020, Apple uploaded a support video to its YouTube account showing how to erase an iPhone. At roughly the 1:43 mark in the video—which has since been pulled—Apple shows how to turn off Find My iPhone, and in doing so revealed a toggle for turning off the feature “Enable Offline Finding.” In the feature’s own words, “Offline finding enables this device and AirTags to be found when not connected to Wi-Fi or cellular.” The video was originally spotted by Appleosophy.To read this article in full, please click here
Apple has not announced an upgrade to the 16-inch MacBook Pro released late last year. But when it does sometime down the road, it’s likely to include the new CPU that Intel just announced. The “10th Gen Intel Core-H Series,” as it is officially named (or “Comet Lake-H” as the hardware enthusiasts call it) will offer clock speeds over 5GHz.Intel calls it the “world’s fastest mobile processor” and it’s the latest salvo in a growing battle between Intel and AMD in the laptop market. Apple has stuck with Intel chips for years and, assuming that continues, the 16-inch MacBook Pro is likely to get an upgrade to these processors later this year. Here’s what you can expect.To read this article in full, please click here
Sadly, our friends don’t all have iPhones. That means some of our Message chats are peppered with green bubbles and send over regular SMS instead of via Apple’s ultra-fast iMessage system. But it’s not just the color and speed that makes iMessage superior: it’s also the clarity and downright watchability when dealing with videos.If you thought the latest Game of Thrones episode was hard to see, clearly you’ve never sent a video from Messages on your iPhone to a friend with an Android phone. If they responded with something like, “What is this?!”, it probably wasn’t because of the content—it’s because they could barely see what was going on in the clip. By the time it reached their device, the video is a blurry, garbled mess. That carefully edited HD clip you took on your new iPhone was reduced to an unwatchable sludge once it reached your friend’s phone. And the same is true of the videos they send you.To read this article in full, please click here

At one point in macOS history, if you had a Play/Pause button on your keyboard, it kept “focus” on whatever the last music app you used was. Then Apple broadened that to include anything with a music player. You could be in iTunes and use the keyboard to pause playback, then switch to YouTube in a browser, press play, and the keyboard would help you play and pause there, too.Or at least most of the time. In my experience and that of many people who post about it, the last music player isn’t always tracked well. That’s especially the case if you close a window in a browser that had a video or audio player in it, and then press the Play/Pause button.To read this article in full, please click here
Video conferencing is bigger than it’s even been now that we’re all keeping our distance from one another, and with Group FaceTime, Apple has an appealing option of its own—provided everyone on the call has either an iPhone, iPad, and Mac. If you’ve been put off by all the iffy privacy decisions being made by popular alternatives like Zoom, this should come as an especially welcome alternative.It’s free, it’s really easy to set up, and Apple even allows a whopping 32 people to take part in a single FaceTime call. Here’s how to do it.How to make a Group FaceTime call through the FaceTime app
We’ll start here since this is the easiest way to start a FaceTime chat with a lot of people, especially if you’ve never called or chatted with them through Messages before. These instructions are for iOS and iPadOS, but we’ve also included instructions for macOS afterward.To read this article in full, please click here
Beginning with the iPhone 8 and iPhone X, Apple added wireless charging to the iPhone. That continued with the iPhone XS and iPhone XR and now the iPhone 11 and iPhone 11 Pro.

Among the TV shows, magazines, and games services unveiled at Apple’s “Show time” event was a surprise entry into a category that couldn’t be further outside Apple’s wheelhouse: a credit card. Dubbed Apple Card, it’s not a traditional plastic credit card that gives you points on things you buy. Rather, it’s a whole new way to shop online and offline. Here’s everything you need to know about it.Updated 04/01/20: Apple Card users can now defer their April payments.The latest: April payments can be deferred
Holders of the Apple Card can defer their April payment. This is in response to the "financial pressure from economic disruption caused by the Covid-19 pandemic," according to Bloomberg. Apple and Goldman Sachs had the same offer for March payments. To read this article in full, please click here
Apple is planting its own flag in the streaming wars with Apple TV+, its in-house streaming service that features only original programming—no reruns of hit TV shows or last year’s blockbuster movies.The company is said to be spending several billion dollars a year on original programming. That’s a lot of TV! Apple is attracting some of the best talent in TV and film production, including huge stars and directors, and locking down the television and movie rights to best-selling books.Though the service is relatively new and has few shows available, there’s a lot in the works. This is a list of all its content for it that we know of so far, along with details about prominent stars, directors, producers, and release dates.To read this article in full, please click here
It was “a wholly new product,” a “futuristic gadget the likes of which we’ve never seen before” that would somehow “soon be viewed with the same nostalgia-tinged contempt we have for the original iPod and iPhone.” After months of debate and speculation in the aftermath of its announcement, ten years ago this week the original iPad arrived and I finally got to review it.Anniversaries are an opportunity to look back in time and ponder how much has changed. I’m happy to report that despite spending a bit too much time dewlling on how the iPad didn’t run Flash, my review from April 2010 does a pretty good job of encapsulating the potential of that original iPad. Re-reading that review today also reminds me that we’re still debating a lot of the same issues that the iPad brought up when it was introduced. The more things change, the more they stay the same.To read this article in full, please click here
Just because you’re working from home now doesn’t mean you’re off the hook when it comes to meetings. And just because you don’t have a spare webcam around doesn’t mean you need to peel back the tape that’s covering your laptop’s camera—as long as you have an iPhone or an iPad, you can easily turn it into a makeshift webcam.There are a few different apps you can use, but we recommend Kinoni’s EpocCam Webcam. Not only is it easy to set up, but the free version with ads and occasional watermarking works with both Mac and PC (iVCam is a good option if you’re using Windows). Any iOS device that’s running iOS 10.3 or later will work, so even if you have an old iPhone 5 or iPad mini 2 in a drawer, it’ll work.To read this article in full, please click here
If you appreciate volume, thump, and durability in a speaker, the Braven BVR-XXL/2 should be at the top of your short list. It's IPX5 rated, sounds good for the weatherized category, and even features a magnetic bottle opener.
Apple has acquired the much-loved weather app Dark Sky.One of the first weather services to use machine learning to make very local and very timely weather predictions, Dark Sky has been a feature on just about every “best weather apps” list since its release back in 2012.What started as a successful Kickstarter project grew into a global weather prediction service used by dozens of apps. Less than a decade later, Dark Sky has announced in a blog post that it has been acquired by Apple.To read this article in full, please click here
Having just released iOS and iPadOS 13.4 on March 24, with big new features like trackpad and mouse support for iPads and iCloud folder sharing, Apple is moving on to its next minor release.For some reason, the company has skipped over iOS 13.4.1 through 13.4.4 and gone right to iOS 13.4.5. That doesn’t mean we won’t see those minor point-releases, only that if we do, we can expect them to be such minor bug or security fixes that Apple would directly release them without an external beta test. We may not see any other significant releases beyond 13.4.5—Apple has never gone to a point-five release in the past. After this, it's likely on to iOS and iPadOS 14 beta testing.To read this article in full, please click here
In a world where I wasn’t confined to my home, this article would be filled with my impressions of Fitbit’s latest fitness tracker, the Charge 4. I would have written about the feel of it on my wrist, the responsiveness of the display, and tested the new Spotify integration that brings playback controls to a Fitbit tracker for the first time.But it's possible that those features wouldn’t have added all that much to my impressions of the device. You see, on the outside, the Fitbit Charge 4 is identical to the Fitbit Charge 3, with an inductive button, 1.36-inch display, and swappable band system. Even the $150 price tag remains. The only visible thing that’s changed is the color: Instead of rose gold, Fitbit now offers a “rosewood” color that’s something of a cross between dark magenta and a deep red wine.To read this article in full, please click here
The MacBook Air is Apple’s best-loved and best-selling laptop. It’s thin, light, powerful enough for most people, and it’s the least expensive option in Apple’s laptop lineup.Apple finally brought the MacBook Air into the modern Mac era in 2018 with the addition of USB-C, Touch ID, a Retina display, and the removal of MagSafe and USB-A. But that laptop also ditched the old scissor-switch keyboard for the much-maligned butterfly keyboard, and boosted the starting price to $1,199 without giving you more storage.In 2019, Apple knocked $100 off the price and added True Tone to the display, but that was it. It’s a fine laptop, but not a particularly good deal. This year, with faster processors, double the starting storage, the new Magic Keyboard, and a $999 starting price, the MacBook Air is back to being the great deal it was before.To read this article in full, please click here
Let us begin this week’s column with a very clear disclaimer: in the times we currently find ourselves stuck in—possibly through some accident involving a warp bubble or rift in the space/time continuum—wondering when you’re going to get a new smartphone is not a critical thought experiment. Let us consider it instead a diversion from having to think about [gestures to everything] rather than an activity that is currently mission-critical. Assuming you already have a smartphone and it’s not on its last legs, you’ll be fine.Consider The Macalope’s position. His beloved iPhone SE is four years old… [checks watch]… nnnnNOW. Isn’t it adorable? They grow up so fast.To read this article in full, please click here

Before they were banned about a half century ago, psychedelic drugs like LSD and psilocybin showed promise for treating conditions including alcoholism and some psychiatric disorders. Researchers say it's time for regulators, scientists, and the public to 'revisit drugs that were once used but fell out of use because of political machinations, especially the war on drugs.'
Over the past few decades, the endangered whooping crane (Grus Americana) has experienced considerable recovery. However, researchers found that habitat loss has led whooping cranes to gather in unusually large groups during migration. While larger groups are a positive sign of species recovery, the authors say that a disease outbreak or extreme weather event could inadvertently impact this still fragile population.
It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. The study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.

Now, researchers have used experiments in the lab and at various altitudes to probe the mechanism of bubble nucleation.
Movement breaks camouflage, making it risky for anything trying to hide. New research has shown that dynamic features common in many natural habitats, such as moving light patterns, can reduce being located when moving.
The Common Nightingale, known for its beautiful song, breeds in Europe and parts of Asia and migrates to sub-Saharan Africa every winter. A new study suggests that natural selection driven by climate change is causing these iconic birds to evolve shorter wings, which might make them less likely to survive their annual migration.
Carbon is essential for life as we know it and plays a vital role in many of our planet's geologic processes -- not to mention the impact that carbon released by human activity has on the planet's atmosphere and oceans. Despite this, the total amount of carbon on Earth remains a mystery, because much of it remains inaccessible in the planet's depths.
Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, researchers have pulled off the feat using video recorded on an ordinary smartphone.

Researchers cross-inserted a new type of electrode made of fibers inside the light emitting layer unlike existing light emitting devices, through which they could develop a new light-emitting technology using an in-plane electric field generated in parallel to the light-emitting layer.
One of the key issues that is holding back widespread applications of noble metal aerogels is a lack of understanding of the underlying structure-performance correlations. Presumably, this is caused by an insufficient understanding of the sol-gel process that limits manipulating versatile parameters, such as ligament sizes, compositions, and spatial element distributions. Recently published findings not only take a big step towards the detailed understanding of reductant chemistry and gelation mechanisms, manipulating the microstructures, and enriching the compositions of NMAs, but also open a new dimension for devising high-performance electrocatalysts by taking advantage of the ligand effects.
Scientists report progress toward a new type of glaze that includes gold and silver nanoparticles, which are less toxic and more environmentally friendly than currently used formulations, while still providing vibrant colors.
