Scientists have created a blazing-fast scientific camera that shoots images at an encoding rate of 156.3 terahertz (THz) to individual pixels equivalent to 156.3 trillion frames per second. Dubbed SCARF (swept-coded aperture real-time femtophotography), the research-grade camera could lead to breakthroughs in fields studying micro-events that come and go too quickly for todays most expensive scientific sensors. SCARF has successfully captured ultrafast events like absorption in a semiconductor and the demagnetization of a metal alloy. The research could open new frontiers in areas as diverse as shock wave mechanics or developing more effective medicine. Leading the research team was Professor Jinyang Liang of Canadas Institut national de la recherche scientifique (INRS). Hes a globally recognized pioneer in ultrafast photography who built on his breakthroughs from a separate study six years ago. The current research was published in Nature, summarized in a press release from INRS and first reported on by Science Daily. Professor Liang and company tailored their research as a fresh take on ultrafast cameras. Typically, these systems use a sequential approach: capture frames one at a time and piece them together to observe the objects in motion. But that approach has limitations. For example, phenomena such as femtosecond laser ablation, shock-wave interaction with living cells, and optical chaos cannot be studied this way, Liang said. SCARFInstitut national de la recherche scientifique The new camera builds on Liangs previous research to upend traditional ultrafast camera logic. SCARF overcomes these challenges, INRS communication officer Julie Robert wrote in a statement. Its imaging modality enables ultrafast sweeping of a static coded aperture while not shearing the ultrafast phenomenon. This provides full-sequence encoding rates of up to 156.3 THz to individual pixels on a camera with a charge-coupled device (CCD). These results can be obtained in a single shot at tunable frame rates and spatial scales in both reflection and transmission modes. In extremely simplified terms, that means the camera uses a computational imaging modality to capture spatial information by letting light enter its sensor at slightly different times. Not having to process the spatial data at the moment is part of what frees the camera to capture those extremely quick chirped laser pulses at up to 156.3 trillion times per second. The images raw data can then be processed by a computer algorithm that decodes the time-staggered inputs, transforming each of the trillions of frames into a complete picture. Remarkably, it did so using off-the-shelf and passive optical components, as the paper describes. The team describes SCARF as low-cost with low power consumption and high measurement quality compared to existing techniques. Although SCARF is focused more on research than consumers, the team is already working with two companies, Axis Photonique and Few-Cycle, to develop commercial versions, presumably for peers at other higher learning or scientific institutions. For a more technical explanation of the camera and its potential applications, you can view the full paper in Nature.This article originally appeared on Engadget at https://www.engadget.com/this-camera-captures-1563-trillion-frames-per-second-184651322.html?src=rss

Apple just announced that the 35th annual Worldwide Developers Conference (WWDC) is set to occur from June 10 until June 14. The annual keynote is scheduled for June 10 at the Apple Park campus in Cupertino, California. The remaining festivities are online and free for developers to attend. What should we expect at this years keynote? WWDC is typically a software-centric event, so reports indicate that Apple will show off a suite of upcoming updates, including iOS 18, iPadOS 18, tvOS 18, macOS 15 and watchOS 11, according to MacRumors. Its also likely the company will reveal the next operating system for the recently-released Apple Vision Pro headset, visionOS 2. Its even possible well get some new hardware announcements. Though typically software-adjacent, last years WWDC was chock full of product announcements, from the aforementioned Vision Pro to the 15-inch M2 MacBook Air. The Mac Mini has been missing from recent product refreshes, so maybe the company will announce an M3-based update. Mark your calendars for #WWDC24, June 10-14. Its going to be Absolutely Incredible! pic.twitter.com/YIln5972ZD Greg Joswiak (@gregjoz) March 26, 2024 As for the new software, there have been plenty of rumors regarding iOS 18. It has been reported that Apple might integrate Googles Gemini AI with Siri and various iPhone apps. Check the suspicious capitalization of "Absolutely Incredible" in the above post from Apple's VP of worldwide marketing Brad Joswiak for a winking acknowledgement of the move. Its also been suggested that the smartphone software will allow users to place apps anywhere on the home screen grid and will offer RCS support in the Messages app, along with the usual array of design changes. The keynote event will be available on the Apple Developer app, the Apple website and YouTube. The company is also inviting 50 winners of its annual Swift Student Challenge to attend WWDC in person.This article originally appeared on Engadget at https://www.engadget.com/apples-wwdc-keynote-is-scheduled-for-june-10-180558453.html?src=rss

Apple's AirTag is the top pick for iPhone owners in our Bluetooth tracker buying guide, unsurprisingly, and right now a four-pack of the little devices is back on sale for $80. We've seen this discount several times since the holiday season, but the bundle has retailed for a few bucks more over the last couple of weeks, so this is a decent time to take advantage. The deal is a few dollars shy of the all-time lowest price we've seen, but it's still $19 cheaper than buying from Apple directly. So long as you want to keep tabs on multiple items, it's also cheaper than buying a few single AirTags, as those are currently going for $24 each. This offer is available at multiple retailers, including Amazon, Target and Walmart. We highlight the AirTag in our guide because it can utilize Apple's giant network of devices to locate items. If you misplace an AirTag-equipped bookbag, for instance, nearby Apple devices can anonymously alert Apple's Find My network when the bag is close, then the Find My app will report that location back to you. Since there are more than two billion iPhones, iPads, Macs and other Apple gadgets active in the wild, the odds of finding something are generally better here than with other trackers that use much smaller crowd-finding networks. Once you're in the vicinity of a lost item, the AirTag uses a wireless connection called ultrawideband (UWB) to more precisely lead you in the right direction, displaying an arrow and distance estimate when you're nearby. The tracker has an IP67 rating, so it can survive a brief dip underwater, and it's one of the few Apple gadgets with an easily replaceable battery. On its own, Apple says the battery is designed to last "more than a year" before it needs changing. The biggest disadvantage the AirTag has compared to competitors like Tile is that it's only available in one shape. Its coin-like design is easy to tuck away but doesn't come with a built-in keyring hole or adhesive. If you want to actually attach it to an item, you need to pay for a separate accessory. It's also worth noting that AirTags aren't designed to find stolen items. They could help with that, but if your AirTag is found moving with someone else, that person will receive an alert telling them so. This feature is meant to hinder those who might use AirTags for stalking, which has been an unfortunate side effect of the device's effectiveness. That said, both Apple and Google have issued updates to further combat bad actors. As a bit of extra security against losing your stuff, the AirTag works well, and this deal makes it a little more accessible. There should be no worry about a new model coming anytime soon, either, as a Bloomberg report earlier this year said a second-generation device isn't expected until 2025. If you own a Samsung Galaxy phone, meanwhile, we'll note that a four-pack of Samsung's Galaxy SmartTag 2 is also on sale for an all-time low of $70. This is another pick in our buying guide: It's not quite as precise as an AirTag and only works with Samsung phones, but it's easy to setup, it has a built-in cutout and it works similarly if you're a committed Galaxy user.

Google has a new version of Chrome for Windows laptops that run Qualcomm Snapdragon processors. The two companies say the Snapdragon version of Chrome shows a dramatic performance improvement. The new Chrome variant is available for download today. Although there are already Snapdragon Windows laptops you can buy, todays announcement is mainly about paving the way for upcoming devices running on the Snapdragon X Elite. Qualcomm says the chip will far surpass the speed of its Snapdragon 8cx Gen 3 line. (But if you have a currently available Snapdragon-running computer, the new Chrome for Snapdragon will work there, too.) Google sees the companies long history of working together on Android (dating back 16 years) as a perk as Qualcomm tries to eat into Intels PC market share. Our close collaboration with Qualcomm Technologies will help ensure that Chrome users get the best possible experience while browsing the Web on current ARM-compatible PCs, Google Senior Vice President Hiroshi Lockheimer wrote in a press release. The first Snapdragon X Elite PCs are scheduled to launch in the middle of this year. The chip is powered by 12 Oryon cores and has what Qualcomm says is double the CPU performance of Intels 13th-gen Core i7-1360P and i7-1355U  while using 68 percent less power. The chip is based on a 4nm design fabricated by TSMC. Typical clock speeds range from 3.8GHz to a dual-core boost of up to 4.3GHz. Qualcomm even says most Windows games will run at nearly full speed without any need to tweak code or change assets. Although Intel is Qualcomms most direct competitor in Windows, its also trying to match or surpass what Apple has done with its M-series silicon. Qualcomms challenge is doing that on different hardware from various companies  something Apple doesnt have to worry about with its integrated model.This article originally appeared on Engadget at https://www.engadget.com/google-says-its-new-version-of-chrome-for-windows-laptops-with-snapdragon-chips-is-much-faster-160041692.html?src=rss
