At 8AM ET today, SpaceX will open a 20-minute launch window for Starship's second-ever fully integrated test flight. If everything goes well during the pre-flight procedures, and if the weather cooperates, then we'll see the company's spacecraft make another attempt to reach space. SpaceX completed Starship's first fully integrated launch in April. While it was considered a success, the company wasn't able to meet all its objectives and had to intentionally blow up the spacecraft after its two stages failed to separate. 

As a result of that incident, the Federal Aviation Administration (FAA) had grounded Starship while authorities conducted an investigation. They found that the explosion scattered debris across 385 acres of land, caused pulverized concrete to rain down on areas up to 6.5 miles northwest of the pad site, and started a wildfire at Boca Chica State Park. The FAA required SpaceX to make 63 corrective actions before it could give the company clearance to fly its reusable spacecraft again. 

SpaceX said that this flight will debut several changes it implemented due to what happened during Starship's first test flight. They include a new hot-stage separation system, a new electronic Thrust Vector Control (TVC) system for Super Heavy Raptor engines, reinforcements to the pad foundation and a water-cooled steel flame deflector.

The company's live broadcast of the launch starts at 7:24AM ET on its website and on X. If the Starship's stages can successfully separate this time around, its upper stage will fly across the planet before splashing down off a Hawaiian coast.

Sam Altman and Greg Brockman were "shocked and saddened by what the board did" and are still trying to figure out what exactly happened. The former CEO and the former President of OpenAI have published a post on X, sharing the details of what they do know and how they found out the former was being fired. Apparently, company co-founder Ilya Sutskever invited Altman for a meeting at noon on Friday, which was then attended by the whole board except for Brockman. It was at that meeting that Altman found out he was being fired and that OpenAI was going to announce it "very soon."

Shortly after that, Sutskever reportedly invited Brockman to a separate Google Meet conference, where he was told that Altman had gotten fired and that he was being removed from the board. However, the rest of the board members told him that he was "vital to the company and would retain his role." Brockman chose to quit on his own. The two former OpenAI executives also said that the rest of the company's management team, other than interim CEO Mira Murati, only found out about the board's decision after Altman was already removed from his post. "The outpouring of support has been really nice; thank you, but please don’t spend any time being concerned," their joint statement reads. "We will be fine. Greater things coming soon."

While OpenAI's c-suite shakeup might have come as a surprise for onlookers, employees were reportedly very much aware that turmoil was already brewing within the organization. According to The Information, Altman's ouster followed internal arguments on whether OpenAI was developing artificial intelligence technology in a safe manner. During the all-hands meeting after Altman's firing, employees asked Sutskever if the CEO's removal was a "coup" or a "hostile takeover." That seems to imply that some personnel were wondering whether the organization's leadership removed Altman because he was was commercializing OpenAI's technology too quickly at the expense of potential safety concerns. 

Bloomberg says Altman and Sutskever were the two people within the organization who butted heads the most when it came to the speed of development and the company's commercialization. Sutskever is one of the two employees leading a team within OpenAI that's dedicated to preventing its technologies from going rogue.

Renowned journalist and podcast host Kara Swisher posted similar information on X. She said employees felt that "the profit direction of the company under Altman and the speed of development" were at odds with the "nonprofit side dedicated to more safety and caution." Swisher also expects more major departures of "top folks" at OpenAI. 

These concerns over the safety of AI development within the organization didn't pop up overnight, however. OpenAI has been grappling with the issue from the beginning, and it's the reason why a group of employees left in 2020 to form their own startup that became known as Anthropic. Still, investors were blindsided by Altman's firing, Forbes reports. Even Microsoft, which pledged to invest $10 billion into the organization over the next few years, reportedly learned about his removal a minute before the announcement went out. 

A remastered version of The Last Of Us Part 2 is coming to the PlayStation 5 in January, according to a leaked trailer from Sony. The new version of the hit post apocalyptic zombie adventure will be available on the platform on January 19, 2024, and will feature improved loading times, 4K graphics in the console's Fidelity mode and full integration with the PS5’s new DualSense wireless controller. Insider Gaming and multiple leakers on X first wrote about the remastered version.

In addition to quality of life improvements, the game will also include a brand new “Roguelike Survival Mode," which will allow players to “choose [their] path through a series of randomized encounters” and play as unlockable characters never before seen in the franchise. The remastered version will also include early versions of three new levels that weren't present in the original game, as well as commentary from developers.

This isn't the first time that a Last of Us trailer has leaked straight from Sony before an official announcement. The same thing happened last year with the remake of The Last of Us Part I.

MIT researchers developed an ingestible capsule that can monitor vital signs including heart rate and breathing patterns from within a patient’s GI tract. The scientists also say that the novel device has the potential to also be used to detect signs of respiratory depression during an opioid overdose. Giovanni Traverso, an associate professor of mechanical engineering at MIT who has been working on developing a range of ingestible sensors, told Engadget that the device will be especially useful for sleep studies.

Conventionally, sleep studies require patients to be hooked up to a number of sensors and devices. In labs and in at-home studies, sensors can be attached to a patient’s scalp, temples, chest and lungs with wires. A patient may also wear a nasal cannula, chest belt and pulse oximeter which can connect to a portable monitor. “As you can imagine, trying to sleep with all of this machinery can be challenging,” Traverso told Engadget.

MIT

This trial, which used a capsule made by Celero Systems —A start-up led by MIT and Harvard researchers— marks the first time ingestible sensor technology was tested in humans. Aside from the start-up and MIT, the research was spearheaded by experts at West Virginia University and other hospital affiliates.

The capsule contains two small batteries and a wireless antenna that transmits data. The ingestible sensor, which is the size of a vitamin capsule, traveled through the gastrointestinal tract, and collected signals from the device while it was in the stomach. The participants stayed at a sleep lab overnight while the device recorded respiration, heart rate, temperature and gastric motility. The sensor was also able to detect sleep apnea in one of the patients during the trial. The findings suggest that the ingestible was able to measure health metrics on par with medical-grade diagnostic equipment at the sleep center. Traditionally, patients that need to get diagnosed with specific sleep disorders are required to stay overnight at a sleep lab, where they get hooked onto an array of sensors and devices. Ingestible sensor technology eliminates the need for that.

Importantly, MIT says there were no adverse effects reported due to capsule ingestion. The capsule typically passes through a patient within a day or so, though that short internal shelf life may also limit how effective it could be as a monitoring device. Traverso told Engadget that he aims to have Celetro, which he co-founded, eventually contain a mechanism that will allow the capsule to sit in a patient’s stomach for a week.

Dr. Ali Rezai, the executive chair of the West Virginia University Rockefeller Neuroscience Institute, said that there is a huge potential for creating a new pathway through this device that will help providers identify when a patient is overdosing according to their vitals. In the future, researchers even anticipate that devices could incorporate drugs internally: overdose reversal agents, such as nalmefene, could be slowly administered if a sensor records that a person’s breathing rate slowed or stopped. More data from the studies will be made available in the coming months.

Samsung’s Frame smart TVs are cheaper than ever in a Black Friday deal that you can snag right now at both Amazon and Samsung direct. The TVs come in 32- to 85-inch configurations, and all of them have some sort of discount. Of note is the 55-inch model, which is 35 percent off and down to $978 — a new record low, and the steepest percent-discount of the bunch. If you’re looking for the biggest dollar-amount savings, that’s on the massive 85-inch TV, which is $1,000 off and on sale for $3,298. 

These are the latest Frame TV models, with QLED displays and support for 4K content, Quantum Dot technology and 100 percent color volume. That quality should be good enough for most people (if you want your next set to be OLED, we recommend checking out these deals on LG, Sony and Samsung OLED TVs), but the real selling point of the Frame series is its ability to blend into your home's decor.

Thanks to its included slim wall mount, anti-reflective matte display and Art Mode, the Frame can mimic a piece of art hanging on your walls when you're note actively watching TV. When we used it, we were also impressed that it comes with an external receiver/port hub/tuner box combo that connects to the panel via a wire, so you could cleverly hide that wire behind a wall or with some accessories to truly make the TV look like it's a floating photo.

The only catch is that Samsung's full collection of displayable art hides behind a $5-per-month paywall. Thankfully, you do get a few pieces of art for free that you can display on the Frame, and you can upload your own photos and images to the Frame from your phone or via a USB drive to display as well. Combine that with the ability to customize the hardware further with a personalized bezel (at an extra cost, of course), and you have a TV that you can make your own and that won't be a big, blocky eyesore in your home like most other sets.

Another major advertiser is pulling its ads from X amid a growing backlash to antisemitic content on the platform. Axios reports that Apple has opted to “pause” all advertising on the platform after its ads were discovered near pro-Nazi posts and X owner Elon Musk appeared to publicly endorse an antisemitic conspiracy theory.

Apple’s pullback comes one day after IBM suspended its ad campaigns on X following a report from watchdog group Media Matters, which found the company's ads appearing next to pro-Nazi content on X. Media Matters also highlighted ads from Apple, Comcast and Oracle, which it said also appeared adjacent to pro-Nazi memes and posts.

An executive at X previously told Engadget that the posts identified by Media Matters were no longer monetizable and that “the X system is not intentionally placing a brand actively next to this type of content, nor is a brand actively trying to support this content with placement.” X CEO Linda Yaccarino also said that “X has also been extremely clear about our efforts to combat antisemitism and discrimination.”

Apple didn’t immediately respond to a request for comment, but this wouldn’t be the first time the company has raised concerns about the direction of the platform under Musk’s leadership, and its role as a major advertiser. Apple CEO Tim Cook said in September the company was “constantly” questioning whether it should continue advertising on X. Apple also briefly paused ads on X (then Twitter) last year, amid a "misunderstanding" between the two CEOs. Musk and Cook later met at Apple’s headquarters in Cupertino and apparently resolved the disagreement.

In a surprise shakeup of its c-suite Friday, OpenAI's board of directors announced that CEO Sam Altman is leaving both the company and the board, effective immediately. Chief Technology Officer Mira Murati has been named interim CEO.

Altman oustering reportedly follows an internal "deliberative review process" which found he had not been "consistently candid in his communications with the board, hindering its ability to exercise its responsibilities," the company announced. As such, "the board no longer has confidence in his ability to continue leading OpenAI."

The board of directors thanked Altman' for his "many contributions to the founding and growth of OpenAI," but believes that "as the leader of the company’s research, product, and safety functions, Mira is exceptionally qualified to step into the role of interim CEO. We have the utmost confidence in her ability to lead OpenAI during this transition period.”

This is a developing story. Please check back for updates.

In a dramatic reversal, Apple announced this week it would offer RCS support starting in 2024. The decision effectively ends one of the most protracted and confusing conflicts between iOS and Android. If you’re not sure what any of that means, don't worry: We're about to lay out what could change with Apple’s adoption of the GSMA’s next-generation messaging protocol. 

What is SMS?

Short Message Service (SMS) is one of the most ubiquitous messaging protocols on the planet. It dates back to the early days of mobile technology. In December 1992, Neil Papworth, at the time an engineer at Vodafone, sent the first SMS text message when he wished his boss “Merry Christmas.” By the start of 2011, approximately 80 percent of all mobile phone users globally — an estimated 3.5 billion people — were sending SMS messages every month.

In 2023, however, the standard has some notable drawbacks. SMS messages are limited to 160 characters, and texts you send can’t include photos, videos, audio or GIFs. For that, cell phones have long turned to a supporting protocol known as Multimedia Messaging Service (MMS), but it too has its share of technical limitations, including woefully small message size limits. SMS also doesn’t support end-to-end encryption.

But for all the ways SMS feels dated in an era dominated by instant messaging platforms, it has one defining advantage: SMS messages are routed through your carrier’s mobile network, meaning a data plan isn’t necessary to use the technology. That fact has meant SMS has often served as a fallback for more advanced protocols, including iMessage.

What is RCS?

RCS is short for Rich Communication Services, though sometimes it is also marketed as “Advanced Messaging.” Either way, it’s often positioned as a next-generation replacement for SMS and MMS. RCS allows users to take advantage of many features that were previously exclusive to over-the-top messaging platforms like WhatsApp.

For instance, the RCS Universal Profile includes full support for read receipts and typing indicators. It can also facilitate proper group chats, and allow users to send high-resolution images, video and audio clips. As of earlier this year, Google’s implementation of RCS also offers by default end-to-end encryption (E2EE) for both one-on-one and group chats.

Unlike SMS texts, RCS messages are routed over a mobile data connection or Wi-Fi link, with SMS functioning as a fallback. For that reason, the older protocol likely isn’t going anywhere anytime soon.

One thing that’s important to remember about RCS is that it is not and has never been envisioned as a replacement or competitor to instant messaging apps. At its heart, RCS is a communication protocol between mobile telephone carriers and between a phone and carrier. Taking advantage of RCS does not require signing up for a new service. As long as your phone and carrier support RCS, and you’re using a compatible app such as Messages by Google, you can take advantage of everything the protocol has to offer — provided, of course, the person or people you’re messaging meet those same requirements.

How does iMessage fit into all this?

Apple announced iMessage in June 2011, a few short months before Steve Jobs died later that same year. Unlike RCS, iMessage is a proprietary messaging protocol controlled exclusively by Apple and available (barring some unofficial workarounds) only on iPhone, iPad, Apple Watch and Mac devices. Starting in 2024, Apple plans to integrate support for RCS in its Messages app. However, at the moment the two protocols do not communicate with one another. As such, Apple’s Messages app will default to SMS/MMS when users attempt to send texts and media files to someone with an Android phone.

From the perspective of an iMessage user, it can feel like Android users are stuck in a bygone messaging era — even though the latter is not at fault for the situation. Due to iMessage’s reliance on SMS/MMS for Android communication, media files end up pixelated, there aren’t any read receipts or typing indicators and forget about trying to involve multiple iPhone and Android users in a single group chat.

How did we get here?

Although work on RCS began before Apple announced iMessage, the protocol had one major disadvantage that doomed it to a slow rollout. RCS is a multi-stakeholder project that includes the involvement of the GSMA, a trade body that represents the interests of the mobile communications industry at large. In 2015, Google took a more active role in the proliferation of RCS when it acquired Jibe Mobile. With Jibe’s technology as a base, it’s effectively Google that provides the glue that binds the RCS ecosystem together, but for a long time, the company did a poor job of aligning everyone involved in RCS toward a shared goal.

In fact, the early days of RCS were marked by false starts, with some carriers, including a group made up of AT&T, T-Mobile and Verizon forming a short-lived joint venture to push the protocol forward before eventually aligning themselves with Google. Even Samsung did its own thing for a while before it too eventually agreed to make Messages by Google the default messaging app it ships on phones in the US.

For that reason, Apple has had little reason to adopt RCS. After all, why would it give a bumbling competitor a freebie? And as recently as last year, it seemed there was little to no chance the situation was going to change anytime soon. "I don't hear our users asking that we put a lot of energy into that," Apple CEO Tim Cook told the Code Conference in 2022 when he was asked about RCS messaging. “Buy your mom an iPhone” was his final word on the matter.

But it was also last year that the European Union passed its landmark Digital Markets and Services Act (DMA). The legislation requires “gatekeepers” to not favor their own systems or limit third parties from interoperating within them. Gatekeepers are any company that meets specific financial and usage qualifications. Apple, according to the law, is one such company. 

At the start of November, Google sent the European Commission arguing that iMessage violates the DMA. It’s probably not an accident that Apple's RCS announcement coincided with the deadline for companies to file challenges to the DMA at the EU’s General Court. On Friday, the EU announced Apple is contesting its DMA assignments. The details of the company’s complaints aren’t public, but Bloomberg reported last week Apple was planning to challenge the gatekeeper designations of both iMessage and the App Store.

Does Apple’s support of RCS mean the end of green text bubbles on iPhone?

It’s too early to tell. On Thursday, Apple provided precious few details about how it plans to display and treat RCS messages within iMessage. What’s more, the company did note its chat app “will continue to be the best and most secure messaging experience for Apple users.” That said, even if you take that statement to mean iMessage will continue to display texts from non-Apple devices differently from those sent from an iPhone, iPad or Mac, Apple’s adoption of RCS will lead to a better user experience for both iOS and Android users.

Again, Apple needs to provide specifics, but it’s easy to envision a future where iMessage, thanks to RCS, properly displays high-resolution images and videos sent from Android phones, and allows both iOS and Android users to take part in group chats without something breaking. On Thursday, Apple also said it would work with GSMA members to improve the existing Universal Profile protocol, with a focus on adding end-to-end encryption to the standard.

Of course, whether that interoperability ends the stigma around green bubbles is harder to answer.

Half-Life is one of the greatest video games of all time and just ahead of its 25th anniversary on Sunday, Valve has released a major update for the first-person shooter. For one thing, the base game now includes Half-Life Uplink. This was a demo of Half-Life, but most of its content doesn't appear in the original game.

Uplink was initially available on CDs that came free with magazines (remember those?) and hardware like sound cards. It's also been available on the internet for a while for those who know where to look. But now players can access it by clicking the New Game button in Half-Life itself.

On top of that, Valve has added four spanking new multiplayer maps. Some might seem familiar, such as one based on an abandoned Xen outpost and another set at an old orbital satellite launch facility. "If we could switch on the oxygen lines, power, and fuel, we might just be able to light this candle," Valve said. The company has added three other maps that were originally available on a disc called Half-Life: Further Data.

You can now, at long last, play the original Half-Life in widescreen without having to resort to mods or the fan remake Black Mesa. Valve has added controller support along with a string of other under-the-hood updates, UI tweaks and bug fixes. Steam Networking support should make multiplayer smoother too.

Although it's a critical part of Valve's history, Half-Life hadn't been Verified for Steam Deck until now. It instead bore the Playable label. "We finally put our game through our own 'Verified' tests, and... we failed super hard," Valve wrote. "So we fixed it! After re-testing the game, Half-Life gets to officially wear the green checkmark." So, that means it should run on your new Steam Deck OLED without a hitch.

Best of all, in case you somehow don't already have it in your library, Half-Life is free on Steam until November 20. Various Half-Life and Valve bundles are on sale too, while Half-Life Alyx is 66 percent off at $20.39.

It's worth noting that Valve now considers the anniversary edition of Half-Life "to be the definitive version, and the one we'll continue to support going forward." As such, Valve says Half Life: Source will be less prominent on Steam, but it will remain available so modders can continue using its assets.

"We launched Half-Life on November 19, 1998. We are very proud of what we built back then and we remain extremely grateful for the community of players who have been enjoying it ever since," Valve said. "The game hasn't received as much attention in recent years as many other titles in our catalog, so we thought this milestone was a great opportunity to spruce up the player experience and add some fun new ways to play the game."

Last but not least, Valve has released a new documentary to mark the 25th anniversary. The 65-minute film features developers and Valve co-founders discussing the company's early days and their memories of working on Half-Life. Happy birthday, Mr. Freeman.
