Oculus VR unveiled the Oculus Rift S, a higher-resolution pair of virtual reality goggles that remove the need for external cameras by incorporating built-in tracking. The company partnered with Lenovo "to help it speed up manufacturing and to improve upon the design of the original Rift," reports The Verge. From the report: The result is a new VR device that is more comfortable, sports 2560 x 1440 resolution (or 1280 x 1440 per eye), and features the same inside-out tracking system that will ship on Oculus' upcoming standalone Quest headset, which the company calls Oculus Insight. That way, you won't need cumbersome cameras to enable full-body movement. In another twist, both the Quest and Rift S device will cost exactly the same at launch: $399, with the same pair of slightly modified Touch motion controllers included and the same integrated audio system (plus a headphone jack for external audio). That decision makes it clear that Oculus wants its VR platform to offer a choice not between two vastly different pieces of hardware, but by the more simple determination of whether you have the hardware to power PC-grade VR. The Rift S will support every existing and future game on the Rift platform. "The company is also enabling cross-buy and cross-play features," the report adds. "That way, you can buy a Quest and, at a later date, upgrade to a Rift S and still have your entire library intact. Additionally, multiplayer games that support both platforms will let players play one another, regardless of whether you're playing on a Quest or Rift device."

The Rift S and Quest will be shipping this spring.

The subscription plan that made MoviePass explode in popularity is coming back. If you're willing to pay for a full year (via ACH payment), "MoviePass Uncapped" will cost the same as the original unlimited plan, namely $9.95 per month, and will allow you to get an unlimited number of 2D movie tickets. TechCrunch reports: Now, you may be thinking that this kind of deal is exactly what got MoviePass into so much trouble last year, to the point where it nearly ran out of money and began announcing new pricing plans and restrictions on a seemingly constant basis. However, the company's announcement today includes multiple references to its ability to "combat violations" of MoviePass' terms of use. And those terms do say that "MoviePass has the right to limit the selection of movies and/or the times of available movies should your individual use adversely impact MoviePass's system-wide capacity or the availability of the Service for other subscribers."

So if you're a heavy MoviePass user, the plan may not be truly unlimited. In addition, you'll only be able to reserve tickets three hours before showtime, and you'll need to check in to the theater between 10 and 30 minutes before the movie starts. Worth noting: the $9.95 per month rate is available only if you pay for a full year, otherwise it will cost $14.95 for a limited time. The regular price will be $19.95 per month.

dryriver writes: Crytek has published a video showing an ordinary AMD Vega 56 GPU -- which has no raytracing specific circuitry and only costs around $450 -- real-time ray tracing a complex 3D city environment at 4K 30 FPS. Crytek says that the technology demo runs fine on most normal NVIDIA and AMD gaming GPUs. As if this wasn't impressive already, the software real-time ray tracing technology is still in development and not even final. The framerates achieved may thus go up further, raising the question of precisely what the benefits of owning a super-expensive NVIDIA RTX 20xx series GPU are. Nvidia has claimed over and over again that without its amazing new RTX cores and AI denoiser, GPUs will choke on real-time ray tracing tasks in games. Crytek appears to have proven already that with some intelligently written code, bog ordinary GPU cores can handle real-time ray tracing just fine -- no RTX cores, AI denoiser or anything else NVIDIA touts as necessary.

Netflix CEO Reed Hastings confirmed that his company won't be playing a role in Apple's upcoming video streaming service. From a report: "We want to have people watch our content on our service," he said Monday. "We've chosen not to integrate into their service." Apple is expected to reveal its offering at an event next Monday. Apple is trying to supplement its original shows by finalizing deals with networks like HBO, Showtime and Starz to license a library of already released content. Hastings pointed out that Netflix has already been competing with Amazon, so it's used to rivals with deep pockets. "You do your best job when you have great competitors," he said, but he acknowledged that sourcing original content is getting more expensive.

NVIDIA's older GeForce GTX 10-series cards will be getting the company's new ray-tracing tech in April. The technology, which is currently only available on its new RTX cards, "will work on GPUs from the 1060 and up, albeit with some serious caveats," reports Engadget. "Some games like Battlefield V will run just fine and deliver better visuals, but other games, like the freshly released Metro Exodus, will run at just 18 fps at 1440p -- obviously an unplayable frame-rate." From the report: What games you'll be able to play with ray-tracing tech (also known as DXR) on NVIDIA GTX cards depends entirely on how it's implemented. In Battlefield V, for instance, the tech is only used for things like reflections. On top of that, you can dial down the strength of the effect so that it consumes less computing horsepower. Metro Exodus, on the other hand, uses ray tracing to create highly realistic "global illumination" effects, simulating lighting from the real world. It's the first game that really showed the potential of RTX cards and actually generated some excitement about the tech. However, because it's so computationally intensive, GTX cards (which don't have the RTX tensor cores) will be effectively be too slow to run it.

NVIDIA explained that when it was first developing the next gen RTX tech, it found chips using Pascal tech would be "monster" sized and consume up to 650 watts. That's because the older cards lack both the integer cores and tensor cores found on the RTX cards. They get particularly stuck on ray-tracing, running about four times slower than the RTX cards on Metro Exodus. Since Metro Exodus is so heavily ray-traced, the RTX cards run it three times quicker than older GTX 10-series cards. However, that falls to two times for Shadow of the Tomb Raider, and 1.6 times for Battlefield V, because both of those games use ray tracing less. The latest GTX 1660 and 1660 Ti GPUs, which don't have RT but do have integer cores, will run ray-traced games moderately better than last-gen 10-series GPUs. NVIDIA also announced that Unity and Unreal Engine now support ray-tracing, allowing developers to implement the tech into their games. Developers can use NVIDIA's new set of tools called GameWorks RTX to achieve this.

"It includes the RTX Denoiser SDK that enables real-time ray-tracing through techniques that reduce the required ray count and number of samples per pixel," adds Engadget. "It will support ray-traced effects like area light shadows, glossy reflections, ambient occlusion and diffuse global illumination (the latter is used in Metro Exodus). Suffice to say, all of those things will make game look a lot prettier."

An anonymous reader quotes a report from ZDNet: Security researchers have spotted a new variant of the Mirai IoT malware in the wild targeting two new classes of devices -- smart signage TVs and wireless presentation systems. This new strain is being used by a new IoT botnet that security researchers from Palo Alto Networks have spotted earlier this year. The botnet's author(s) appears to have invested quite a lot of their time in upgrading older versions of the Mirai malware with new exploits. Palo Alto Networks researchers say this new Mirai botnet uses 27 exploits, 11 of which are new to Mirai altogether, to break into smart IoT devices and networking equipment. Furthermore, the botnet operator has also expanded Mirai's built-in list of default credentials, that the malware is using to break into devices that use default passwords. Four new username and password combos have been added to Mirai's considerable list of default creds, researchers said in a report published earlier today.

The purpose and modus operandi of this new Mirai botnet are the same as all the previous botnets. Infected devices scan the internet for other IoT devices with exposed Telnet ports and use the default credentials (from their internal lists) to break in and take over these new devices. The infected bots also scan the internet for specific device types and then attempt to use one of the 27 exploits to take over unpatched systems. The new Mirai botnet is specifically targeting LG Supersign signage TVs and WePresent WiPG-1000 wireless presentation systems.

To avoid copyright claims, "YouTube creators and Twitch streamers have been performing terrible a capella covers of popular songs," reports the Verge: React videos are a huge part of YouTube's current culture; people lift popular movie trailers and film their reactions to what's happening on-screen. These videos are typically monetized... In recent months, YouTube creators have run into copyright issues while making TikTok reaction videos, where they collect cringey TikTok clips and either react or provide commentary on them. [T]hose TikTok videos contain music from artists signed to labels like Sony and Warner, and those labels will issue copyright claims, preventing creators from monetizing their videos... TikTok videos include less than 10 seconds of music, yet that can still be enough to receive a copyright claim -- on TikTok itself, the music is all licensed from the labels...

To work around that, creators like Danny Gonzalez and Kurtis Conner have started replacing the music with their own singing. Gonzalez and Conner half-heartedly sing songs like Linkin Park's "In The End" and Imagine Dragons' "Believer" while the corresponding TikTok video plays on screen... It's a little painful to hear, but ultimately a very fun loophole in the copyright system that YouTube has to enforce... The hope is that major labels like Sony Music or Warner Music Group can't claim copyright infringement, or at least that the singing won't trigger YouTube's automated system for finding copyrighted content.

CNBC reports Dungeons and Dragons "has found something its early fans never expected: Popularity." The days of hiding away in a basement rolling dice and playing "Dungeons and Dragons" in darkness is over. More than 40 years after the first edition of "Dungeons and Dragons" hit shelves, video platforms Twitch and YouTube are leading a renaissance of the fantasy roleplaying board game -- and business is booming. "DnD has been around for 45 years and it is more popular now than it has ever been," said Greg Tito, senior communications manager, at Wizards of the Coast. In each of the last five years, sales of "Dungeons and Dragons" merchandise has grown by double digits.

The company, owned by toymaker Hasbro, attributes this massive sales boom to the launch of the fifth edition of the game in 2014 and to "Critical Role," a weekly show on live streaming video platform Twitch that features voice actors from TV shows and video games playing "Dungeons and Dragons...." "When a new edition for a game like this releases, there is that flurry of activity, people get really excited about it and then, historically, that excitement has waned," he said. "The fifth edition has completely blown that model out of the water. With the release in 2014, it has grown and only continued to grow. Every kind of statistical model we've been able to to use from the history of 'Dungeons and Dragons' has been broken at this point. So, we are in uncharted territory...."

"Critical Role" has become so popular that when it launched a Kickstarter last week to create an animated special based on the characters from the first campaign, it was funded within one hour. The team behind the web series had wanted $750,000 to fund the endeavor. With 33 days remaining in the crowdfunding campaign, "Critical Role" has raised more than $7.3 million from 53,000 backers.

It is now the most-funded film/video project in Kickstarter history.
Over the years Dungeons & Dragons -- and the people who played it -- have usually been played for laughs in TV sitcoms like Freaks and Geeks, several episodes of Community, and an episode of Big Bang Theory with William Shatner, Joe Manganiello, Kevin Smith, and Kareem Abdul-Jabbar.

Police in Australia have arrested a man who allegedly made AU $300,000 (US $211,000) running a website which sold the account passwords of popular online subscription services including Netflix, Spotify, Hulu, PSN, and Origin. From a report: The 21-year-old man was arrested on Tuesday in Sydney, Australia, following an international investigation by the FBI and the Australian Federal Police into the website Wicked Gen. The Wicked Gen website bragged that it had over 120,000 users and almost one million sets of account details, offering monthly and yearly membership plans for those who wanted "access to thousands of premium accounts across a huge range of services." The account passwords, however, were not obtained via legitimate means. Instead the details were typically obtained through credential stuffing using swathes of usernames and passwords leaked through other data breaches, without the knowledge of their genuine owners.

Google is shutting down its Spotlight Stories immersive entertainment unit, according to an email sent out by Spotlight Stories executive producer Karen Dufilho Wednesday evening. "Google Spotlight Stories is shutting its doors after over six years of making stories and putting them on phones, on screens, in VR, and anywhere else we could get away with it," Dufilho said in her email sent to supporters of the studio. Variety reports: Spotlight Stories originally began as a group within Motorola, tasked with exploring the future of storytelling for mobile devices. The group then became part of Google's Advanced Technologies and Products (ATAP) group, and went on to produce a number of 360-degree videos and VR experiences with creators like Glen Keane, Justin Lin, Jorge Gutierrez and Aardman Animation, the makers of "Wallace and Gromit." "Pearl," a Spotlight Story from Patrick Osborne, the director of Disney's Oscar-nominated short film "Feast," was nominated for an Academy Award, and won a Creative Arts Emmy for Outstanding Innovation in Interactive Programming in 2017. Most recently, Spotlight Stories released "Age of Sail," an animated short film directed by Oscar-winning animator John Kahrs.

Google is said to have invested significant amounts of money into Spotlight Stories over the years, without giving the group a mandate to monetize their works. However, while Spotlight Stories films pushed the medium forward, the group didn't necessarily improve the fortunes of Google's VR efforts, with the company struggling to find an audience for its Daydream VR headset. A Google spokesperson said in a statement to Variety: "Since its inception, Spotlight Stories strove to re-imagine VR storytelling. From ambitious shorts like 'Son of Jaguar,' 'Sonaria' and 'Back to The Moon' to critical acclaim for 'Pearl' (Emmy winner and first-ever VR film nominated for an Oscar) the Spotlight Stories team left a lasting impact on immersive storytelling. We are proud of the work the team has done over the years." A source with knowledge of the situation told Variety that staffers were given a chance to look for new positions within the company. Most artists who had been working on projects for Spotlight Stories were thought to be contractors on a by-project basis.

An anonymous reader quotes a report from Motherboard: Now, for Pi Day (March 14), music software programmer Canton Becker has crafted a million-hour song based on Pi that unfolds generatively on a virtual tape deck. Titled "Shepard's Pi," the song combines two of Becker's favorite infinities: Pi, and an auditory illusion called a Shepard tone, which he describes as an "unsettling sonic illusion of a pitch that climbs or descends forever, never reaching a top or a bottom." Found at PiSongs.com, users can tune into "Shepard's Pi" in real time with a custom virtual tape deck. The track itself evolves moment to moment, but the synthesized and sampled tones will be familiar to anyone who has ever listened to the electronic music of Kraftwerk, Tangerine Dream, Aphex Twin, and Global Communication. Far from being a mere gimmick, it is a highly evocative and transporting piece of electronic music, alternately ambient, glitchy, and interestingly rhythmic. The 58,999 GB MP3 file needed to be distributed via a webpage or app, so Becker "started hacking away at the basic algorithm in the programming languages PHP and Javascript," reports Motherboard. "In between coding marathons, Becker composed and recorded the loops and samples that would form the basis of the song. He experimented with sounds that would work well together regardless of being stacked one upon the other."

"When users hit 'play' on the virtual tape deck, the algorithm actually 'performs' the piece," the report says. "This way, the 114-year song can fit in just one gigabyte of space, which is mostly comprised of the digits of Pi. The virtual tape deck was also a solution to a built-in quirk of browsers such as Chrome, Safari, and Firefox -- users must click on a webpage to trigger a sound." From start to finish, the song lasts 999,999 hours, "a limitation imposed by only considering the first one billion digits of Pi."

Microsoft is bringing its Xbox Live network to iOS and Android devices. "The software giant is launching a new cross-platform mobile software development kit (SDK) for game developers to bring Xbox Live functionality to games that run on iOS and Android," reports The Verge. "Xbox Live features like achievements, Gamerscore, hero stats, friend lists, clubs, and even some family settings will all be available on iOS and Android." From the report: It's all part of a bigger push from Microsoft to make its Xbox games and services available across multiple platforms. Game developers will be able to pick and choose parts of Xbox Live to integrate into their games, and it will all be enabled through a single sign-in to a Microsoft Account. Microsoft is using its identity network to support login, privacy, online safety, and child accounts. Microsoft wants game developers to take a similar Minecraft approach and bring Xbox Live to more mobile games. Some iOS and Android games already have Xbox Live Achievements, but they're only enabled in titles from Microsoft Studios at the moment and this new SDK will open up Xbox Live functionality to many more games.

If you were hoping to see Xbox Live on Nintendo Switch then you might have to wait a little longer. "Our goal is to really unite the 2 billion gamers of the world and we're big fans of our Xbox Live community, but we don't have any specific announcements as it relates to Switch today," reveals Choudhry. Xbox Live on PlayStation 4 also looks unlikely, but Microsoft is open to the idea if Sony is willing to allow it. "If you've watched us for the past few years, we've taken a very inclusive approach," says Choudhry. "Phil [Spencer] has been very proactive on issues like crossplay, cross-progression, and uniting gamer networks, and we're willing to partner with the industry as much as we possibly can."

DarkRookie2 shares a report from Ars Technica: After a seemingly endless run of rumors, the news Halo fans have been waiting for is here: the series is finally coming back to PC, and in pretty big fashion. Halo: The Master Chief Collection will arrive on Windows PCs "later this year," according to the official Halo Waypoint site, and fans will be able to buy the collection either via Steam or the Windows Store. (Anybody who's dealt with Windows 10's UWP woes will appreciate this rare example of Microsoft launching one of its first-party games on Steam at the same time as Windows Store, as opposed to delaying a Steam version for a few months.)

The game's listing confirms that PC gamers can look forward to full mouse-and-keyboard control support, along with support for resolutions up to 4K and an HDR toggle. Whether this version will also include the kinds of tweaks that hardcore PC gamers crave -- including ultra-widescreen ratios, higher frame rates, and fully remappable controls -- remains to be seen. We highly doubt Microsoft will include official mod support beyond letting players use individual games' built-in "Forge" creation tools. Halo Reach will also join the MCC when it launches on PC. Unfortunately, there's no word on cross-platform play.

An anonymous reader quotes a report from the BBC: I've had one desire since I was born; to see my body ripped and torn. The lyrics of death metal band Bloodbath's cannibalism-themed track, Eaten, do not leave much to the imagination. But neither this song -- nor the gruesome lyrics of others of the genre -- inspire violence. That is the conclusion of Macquarie University's music lab, which used the track in a psychological test. It revealed that death metal fans are not "desensitized" to violent imagery. The findings are published in the Royal Society journal Open Science. How do scientists test people's sensitivity to violence? With a classic psychological experiment that probes people's subconscious responses; and by recruiting death metal fans to take part. The test involved asking 32 fans and 48 non-fans listen to death metal or to pop whilst looking at some pretty unpleasant images.

Lead researcher Yanan Sun explained that the aim of the experiment was to measure how much participants' brains noticed violent scenes, and to compare how their sensitivity was affected by the musical accompaniment. To test the impact of different types of music, they also used a track they deemed to be the opposite of Eaten. "We used 'Happy' by Pharrell Williams as a [comparison]," said Dr Sun. Each participant was played Happy or Eaten through headphones, while they were shown a pair of images -- one to each eye. One image showed a violent scene, such as someone being attacked in a street. The other showed something innocuous -- a group of people walking down that same street, for example. "If fans of violent music were desensitized to violence, which is what a lot of parent groups, religious groups and censorship boards are worried about, then they wouldn't show this same bias. "But the fans showed the very same bias towards processing these violent images as those who were not fans of this music."

Valve has announced the "early beta" release of Steam Link Anywhere, which will enable streamed gaming to any compatible device, and Steam Networking Sockets APIs, granting developers access to the technology and infrastructure that underlies CS:GO and Dota 2. PC Gamer reports: Steam Link Anywhere is an extension of Steam Link that will enable users to connect to their PCs and play games from anywhere (thus the name), rather than being limited to a local network. It's compatible with both the Steam Link hardware and app, and will be rolled out automatically (and freely) to everyone who owns the hardware with beta firmware installed, the Android app beta, or the Raspberry Pi app. You'll also need to be enrolled in the Steam client beta, and have the latest version installed. Assuming you've got all that covered, you'll see an "Other Computer" option on the screen when searching for computers to connect to via Steam Link. Select that, follow the instructions, and you'll be set. Valve didn't provide specific network requirements but said you'll need "a high upload speed from your computer and strong network connection to your Steam Link device" in order to use it.

Steam Networking Sockets APIs isn't as flashy (and that "flash" is definitely relative) but is aimed squarely at developers, and could be even more significant to Steam's fortunes given the pressure it's facing from the Epic Games Store: It enables developers to run their game traffic through Valve's own private gaming network, providing players "faster and more secure connections." It's free for developers, and "a large portion" of the API is now open source, which could be a pretty big draw for devs look to incorporate online play with a minimum of fuss. If that's your bag, you can get more detailed information at steamcommunity.com, and Valve will be talking about the new feature in-depth at a Game Developer's Conference panel next Thursday, March 21.

Smart TV manufacturer Vizio has formed a partnership with nine media and advertising companies to develop an industry standard that will allow smart TVs to target advertisements to specific households, the companies said this week. From a report: The consortium includes major TV networks like Comcast Corp's NBCUniversal and CBS, as well as advertising technology companies like AT&T's Xandr. Addressable advertising, or targeting viewers on the household level based on their interests, has long been the goal of TV marketers. But TVs lack cookies that internet browsers use to allow ads to follow people around the web. [...] The consortium of companies, dubbed Project OAR, or Open Addressable Ready, hopes to define the technical standards for TV programmers and platforms to deliver addressable advertising on smart TVs, which are WiFi-enabled TVs with apps for services like Netflix Inc and Hulu, by the end of this year, McAfee said. Further reading: In January this year, Bill Baxter, chief technology officer of Vizio, spoke about business of data collection in an interview. He said: It's about post-purchase monetization of the TV. This is a cutthroat industry. It's a 6-percent margin industry, right? I mean, you know it's pretty ruthless. You could say it's self-inflicted, or you could say there's a greater strategy going on here, and there is. The greater strategy is I really don't need to make money off of the TV. I need to cover my cost. And then I need to make money off those TVs. They live in households for 6.9 years -- the average lifetime of a Vizio TV is 6.9 years. You would probably be amazed at the number of people come up to me saying, "I love Vizio TVs, I have one" and it's 11 years old. I'm like, "Dude, that's not even full HD, that's 720p." But they do last a long time and our strategy -- you've seen this with all of our software upgrades including AirPlay 2 and HomeKit -- is that we want to make things backward compatible to those TVs. So we're continuing to invest in those older TVs to bring them up to feature level comparison with the new TVs when there's no hardware limitation that would otherwise prevent that.

Scientists have developed an "acoustic meta-material" that can catch certain frequencies passing through the air and reflect them back toward their source. When a loudspeaker was placed into one end of a PVC pipe with a 3D-printed ring of the metamaterial, the ring "cut 94% of the sound blasting from the speaker, enough to make it inaudible to the human ear," reports Fast Company. From the report: Typical acoustic paneling works differently, absorbing sound and turning the vibrations into heat. But what's particularly trippy is that this muffler is completely open. Air and light can travel through it -- just sound cannot. The implications for architecture and interior design are remarkable, because these metamaterials could be applied to the built environment in many different ways. For instance, they could be stacked to build soundproof yet transparent walls. Cubicles will never be the same.

The researchers also believe that HVAC systems could be fitted with these silencers, and drones could have their turbines muted with such rings. Even in MRI machines, which can be harrowingly loud for patients trapped in a small space, could be quieted. There's really no limit to the possibilities, but it does sound like these silencers will need to be tailored to circumstance. "The idea is that we can now mathematically design an object that can blocks the sounds of anything," says Boston University professor Xin Zhang, in a press release. You can see a demo of the noise cancellation device here.

Microsoft has announced a form of DirectX 12 that will support Windows 7. "Now before you get too excited, this is currently only enabled for World of Warcraft; and indeed it's not slated to be a general-purpose solution like DX12 on Win10," reports AnandTech. "Instead, Microsoft has stated that they are working with a few other developers to bring their DX12 games/backends to Windows 7 as well. As a consumer it's great to see them supporting their product ten years after it launched, but with the entire OS being put out to pasture in nine months, it seems like an odd time to be dedicating resources to bringing it new features." From the report: For some background, Microsoft's latest DirectX API was created to remove some of the CPU bottlenecks for gaming by allowing for developers to use low-level programming conventions to shift some of the pressure points away from the CPU. This was a response to single-threaded CPU performance plateauing, making complex graphical workloads increasingly CPU-bounded. There's many advantages to using this API over traditional DX11, especially for threading and draw calls. But, Microsoft made the decision long ago to only support DirectX 12 on Windows 10, with its WDDM 2.0 driver stack.

Today's announcement is a pretty big surprise on a number of levels. If Microsoft had wanted to back-port DX12 to Windows 7, you would have thought they'd have done it before Windows 7 entered its long-term servicing state. As it is, even free security patches for Windows 7 are set to end on January 14, 2020, which is well under a year away, and the company is actively trying to migrate users to Windows 10 to avoid having a huge swath of machines sitting in an unpatched state. In fact, they are about to add a pop-up notification to Windows 7 to let users know that they are running out of support very soon. So adding a big feature like DX12 now not only risks undermining their own efforts to migrate people away from Windows 7, but also adding a new feature well after Windows 7 entered long-term support. It's just bizarre.

jbmartin6 shares a report from Scientific American: In a paper published in Physical Review Letters, a group of scientists has theorized that sound waves possess mass, meaning sounds would be directly affected by gravity. They suggest phonons, particle-like collective excitations responsible for transporting sound waves across a medium, might exhibit a tiny amount of mass in a gravitational field. "You would expect classical physics results like this one to have been known for a long time by now," says Angelo Esposito from Columbia University, the lead author on the paper. "It's something we stumbled upon almost by chance."

Esposito and his colleagues built on a previous paper published last year, in which Alberto Nicolis of Columbia and Riccardo Penco from Carnegie Mellon University first suggested phonons could have mass in a superfluid. The latest study, however, shows this effect should hold true for other materials, too, including regular liquids and solids, and even air itself. And although the amount of mass carried by the phonons is expected to be tiny -- comparable with a hydrogen atom, about 10^-24 grams -- it may actually be measurable. Except, if you were to measure it, you would find something deeply counterintuitive: The mass of the phonons would be negative, meaning they would fall "up." Over time their trajectory would gradually move away from a gravitational source such as Earth. "If their gravitational mass was positive, they would fall downward," Penco says. "Because their gravitational mass is negative, phonons fall upwards." And the amount they would "fall" is equally small, varying depending on the medium the phonon is traveling through. In water, where sound moves at 1.5 kilometers per second, the negative mass of the phonon would cause it to drift at about 1 degree per second. But this corresponds to a change of 1 degree over 15 kilometers, which would be exceedingly difficult to measure.

Apple is holding an event on March 25th where it's expected to announce its long-rumored TV streaming and Apple News subscription services. The invitation shows an animated countdown GIF with the caption "It's show time," hinting that the new TV service will play a big role. The Verge reports: Rumors of an event at the end of March began last month, saying that the company will reportedly focus exclusively on services. Although, there is always a chance that we could see the anticipated announcements of revamped AirPods, a new entry-level iPad, and the long-delayed AirPower wireless charging pad. This is not the first time that Apple has used this tagline for an event: the company first used it for a September 2006 event where it announced that it would start offering movies on iTunes, along with the first reveal of the iTV (which would be renamed Apple TV on release in 2007). It's certainly a fitting teaser for the upcoming event. Just like in 2006, we could see Apple's media offerings for its devices expand yet again.

Along with the TV service, which is rumored to launch later this spring, Apple is also expected to take the wraps off its Apple News subscription service. The Apple News service will reportedly look to offer a Netflix-style bundle for magazines and subscription newspapers all in one convenient place. An early report from The Wall Street Journal indicated that Apple was having trouble with negotiations, reportedly demanding a staggering 50 percent of revenue from the service.
