This is the second part of a series in which we examine history from a different angle. The business card has been in its popular analog cardboard format for just over 200 years – a period in which society and scientific knowhow have moved at warp speed. The earliest card in our top 100 is that of James Watt (of steam engine fame), and at the other end of our list are a dozen people still handing out their cards to this day.

What is an actual survival tool supposed to do? Sure, having a Swiss Army knife is all fun and games until you find yourself wanting to see in the dark, start a fire, drink water straight from a stream, or heck, even charge your phone!

What if your drinking water didn't come from old, rusty apartment building pipes or from a plastic bottle that's going to end up in a landfill ... or in the ocean? What if your drinking water (and coffee?) literally just came out of thin air?

Apple kicked off its Worldwide Developers Conference (WWDC) today. During the keynote to mark the event's start, the company revealed that it is completely redesigning the iPhone’s camera app in the next version of its mobile operating system, iOS 26*. The company says the design will be “more intuitive” and “elevate the two capture modes you use most: photo and video.”
The iPhone’s camera app has looked largely the same since the last big iOS redesign, 2013’s iOS 7. However, the company has added dozens of new features and modes since then, making the app feel cluttered to some users. For example, if you want to take a panorama, you have to swipe through the portrait and spatial photo modes first.
Different modes will be broken into subcategories for both photo and video, making it easier to find what you want.

By default, the new interface will present you with the modes for shooting standard photos and videos. You can access other modes, like “cinematic” video or portrait photos, through a series of swipes. The different modes are now sub-categories for photos and videos, which should make it much easier to switch between stills and motion pictures.
The app also follows Apple's “Liquid Glass” design language, which will be applied to the rest of iOS 26. This means that settings and controls will be displayed as semi-transparent windows over the photo preview; the current version of the app has a few settings panes, which appear on black bars beside the preview.
Apple is bringing tabs to its Photos app.

The Photos app, which was subject to a relatively controversial redesign last year, is also getting a fresh coat of “Liquid Glass” paint. Beyond the purely aesthetic changes, your photo library and collections of albums and photo types will now live in different tabs, which should make them easier to differentiate; in the iOS 18 version, they were presented together on one scrolling screen.
Finally, Apple is also updating its AirPod wireless earbuds by adding camera remote functionality. Users will be able to press and hold the AirPods stem to take a photo or start recording a video. A press-and-hold will end the recording. Apple says this function will work with its native camera app, as well as "compatible third-party camera apps on iPhone or iPad."
Apple says iOS 26 will be available "this fall," and it'll run on iPhone 11 and later; Apple is dropping support for the iPhone XS and XR, which can run iOS 18.
Developing. Please check back later for updates.
* The current release is known as iOS 18, but Apple has changed its naming scheme; it will now follow a model year format similar to cars. Eg., iOS 26 will presumably release in late 2025.

Canon's PowerShot V1 is a vlogging-focused compact camera with an ambitious 18-50mm equivalent lens. As part of our upcoming review, we've shot our studio test scene, to see how it performs.
The shots in the comparison tool were all shot at 50mm equiv and F5.6, as this is the closest the camera can get to our standard 85mm equivalent focal length and consequent working distance that we try to use as broadly as possible.
We shot some images at the camera's wide-open F4.5 setting and found the corners were significantly less sharp than they are by F5.6, so used our standard exposure values throughout.
Image ComparisonThis widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab.As we suspected, the pixel-level noise performance of the V1 is very similar to that of the EOS R7, whose sensor is very similar, but with a consequent disadvantage of around half a stop, when compared at the whole-image level, because of its smaller active sensor area.
This puts the V1 comfortably ahead of Sony's ZV-1 Mark II vlogging compact, but behind its ZV-E10 II mirrorless vlogging camera.
Detail levels in the JPEG are good, but the Raw results suggest it's having to apply a fair amount of sharpening and contrast to get the results it is.
Wide-angle performance:Our studio scene isn't intended as a lens test chart but we thought it'd be interesting to see how it performs at its widest setting, too.

As we'd expect of such a small lens delivering an ultrawide field of view in front of a relatively large sensor, its design includes a significant amount of digital correction of geometric distortion.
However, despite producing an alarming-looking projection if you hack away that element of the lens design, the final results (derived from around 80% of the sensor area) are surprisingly good.
It's quite difficult to precisely align such a wide lens with our chart, which can undermine consistency between the four corners, yet despite this potential source of error, all four corners look pretty detailed. The far extremes of the corners get distinctly blurry but we were quite impressed by the performance for a retractable zoom that goes this wide.
And, of course, it's less of a concern for vloggers, where those extreme corners won't be used for the 16:9 output footage.

Using more sludge and less slag in their recipe, researchers were able to create a material that's stronger than even today's enhanced cements and highly resistant to corrosion by acid. It could solve a serious problem facing sewer pipes worldwide.

A common fatty acid in olive oil, as well as many other plant oils, has been found to stimulate the body's production of new fat cells, creating conditions that could – over time – lead to more fat storage and unintended weight gain. Until now, weight gain linked to this fatty acid was attributed to the high calorie content of foods that it's found in.

Switching from a diet including meat to a low-fat vegan diet reduced severe hot flashes in menopausal women by a staggering 92%, according to a new study. Interestingly, the benefit was seen even if the women ate highly processed plant-based foods.

There are times when a cargo ebike becomes an attractive alternative to the family car when heading into town to pick up a few groceries. If you can't afford to splurge a couple of grand for infrequent use, shared mobility outfit Veo has launched the first dockless model in North America.

There are no written Soviet records, no logs, no official drilling reports, and no confirmation that they'd lit it intentionally – but there's no disputing a ~100-foot (~30-m) deep, 226-foot (69-m) wide pit of relentless fiery fury that's been burning for around 50 years in the Karakum Desert of Turkmenistan.

When we tried the world's first true wireless earbuds almost 10 years ago, battery life for continuous listening came in at around 2 hours. The latest buds from Anker's Soundcore brand last for 12 hours, or 192 hours with a charging case that could also juice up your phone.

Did anyone really think Nitecore was going to stop at 6,000 lumens? Well, full confession, we did think it might stop for a few more months, at least. But adding more output to its sleek, remote control-like EDC torch lineup seemed a certainty in time. And the time is now – the new flagship EDC37 launches a full 8,000-lumen strategical attack on darkness without growing but a couple ounces. No, that full power burst won't last long at all, but you will enjoy over seven hours of four-figure lumens, which should suffice in even Earth's darkest recesses.

Whichever way you cut it, a 5.4-m (17.8-ft)-long tiny house isn't going to feel palatial. However, thanks to some clever interior design choices, the Five Four does a good job of maximizing its limited footprint and even squeezes in two bedrooms.

Visitors soar through the air on a ride at the Washington State Fair. I captured this photo while shooting a sample gallery for the Ricoh GR IIIx, which – unsurprisingly – proved to be an excellent camera for candid photography. To me, this photo embodies both the essence of summer and the magic of a cherished American summer tradition: state fairs.
