Artifact, the buzzy news app from Instagram co-founders Kevin Systrom and Mike Krieger, is shutting down less than a year after its launch. In a note on Medium, Systrom said the app’s “core news reading” features would be online through the end of February, but that it would remove commenting and posting abilities immediately.

Besides its famous founding team, the app was known for AI-centric features as well as Reddit-like commenting and posting abilities. The app had won praise from journalists who appreciated reporter-friendly features like dedicated author pages and had been featured prominently in Apple and Google’s app stores.

But after a year of work, it seems Systrom and Krieger encountered many of the same struggles as founders of buzzy news apps before them. “We have built something that a core group of users love, but we have concluded that the market opportunity isn’t big enough to warrant continued investment in this way,” Systrom wrote.

While he didn’t say what he might do next, Systrom’s note hinted that he may at some point take on a new AI-focused project. “I am personally excited to continue building new things, though only time will tell what that might be,” he wrote. “We live in an exciting time where artificial intelligence is changing just about everything we touch, and the opportunities for new ideas seem limitless.”

In the meantime, Artifact fans have a few more weeks to keep checking headlines before the app goes offline for good.

Researchers at MIT’s CSAIL division, which focuses on computer engineering and AI development, built two machine learning algorithms that can detect pancreatic cancer at a higher threshold than current diagnostic standards. The two models together formed to create the “PRISM” neural network. It is designed to specifically detect pancreatic ductal adenocarcinoma (PDAC), the most prevalent form of pancreatic cancer.

The current standard PDAC screening criteria catches about 10 percent of cases in patients examined by professionals. In comparison, MIT’s PRISM was able to identify PDAC cases 35 percent of the time.

While using AI in the field of diagnostics is not an entirely new feat, MIT’s PRISM stands out because of how it was developed. The neural network was programmed based on access to diverse sets of real electronic health records from health institutions across the US. It was fed the data of over 5 million patient’s electronic health records, which researchers from the team said “surpassed the scale” of information fed to an AI model in this particular area of research. “The model uses routine clinical and lab data to make its predictions, and the diversity of the US population is a significant advancement over other PDAC models, which are usually confined to specific geographic regions like a few healthcare centers in the US,” Kai Jia, MIT CSAIL PhD senior author of the paper said.

MIT’s PRISM project started over six years ago. The motivation behind developing an algorithm that can detect PDAC early has a lot to do with the fact that most patients get diagnosed in the later stages of the cancer’s development — specifically about eighty percent are diagnosed far too late.

The AI works by analyzing patient demographics, previous diagnoses, current and previous medications in care plans and lab results. Collectively, the model works to predict the probability of cancer by analyzing electronic health record data in tandem with things like a patient’s age and certain risk factors evident in their lifestyle. Still, PRISM is still only able to help diagnose as many patients at the rate the AI can reach the masses. At the moment, the technology is bound to MIT labs and select patients in the US. The logistical challenge of scaling the AI will involve feeding the algorithm more diverse data sets and perhaps even global health profiles to increase accessibility.

Nonetheless, this isn’t MIT’s first stab at developing an AI model that can predict cancer risk. It notably developed a way to train models how to predict the risk of breast cancer among women using mammogram records. In that line of research, MIT experts confirmed, the more diverse the data sets, the better the AI gets at diagnosing cancers across diverse races and populations. The continued development of AI models that can predict cancer probability will not only improve outcomes for patients if malignancy is identified earlier, it will also lessen the workload of overworked medical professionals. The market for AI in diagnostics is so ripe for change that it is piquing the interest of big tech commercial companies like IBM, which attempted to create an AI program that can detect breast cancer a year in advance.

The Environmental Protection Agency has scrapped a plan to phase out mammal testing for studying chemical toxicity, Science reports. In 2019, the regulatory agency vowed to completely phase out animal testing for toxicology studies by 2035 in favor of non-animal “test subjects” programmed into computer models.

The call to challenge the status quo was controversial from the start — it not only was going to impact thousands of studies and experiments, but many scientists argued that computer models were nowhere near ready to replace animals as test subjects. In a letter written by a group of public health officials, the experts urged the EPA’s head Michael Regan to reconsider the ban because computational models, in their opinion, were “not yet developed to the point” where they could be relied on for risk assessments.

In order for the new ban to have taken effect, the EPA said there needed to be “scientific confidence” that non-animal models could soundly replace critters like mice and rabbits in labs. Despite the 2035 deadline being put on ice, however, an EPA spokesperson told Science that it would still explore alternatives to animal testing.

The ambitious plan is not entirely a lost cause, though. While the EPA hasn’t made any official statements about how it plans to work toward its original goal, now without a deadline, some studies have shown promise that computational models might effectively reflect the toxicology of certain chemicals during testing. In some instances, these studies suggest, they can even outperform lab rats.

3D developments like technical organoids are also popping up on the research front by way of stem cells that allow duped livers to be tested and evaluated during research as a human liver would. Labs are currently working on ways to more effectively develop realistic organs using 3D printers. But it might be a while before 3D printing can consistently be used to assist biologists and pharmacologists for research and drug testing.

NASA’s X-59 Quesst supersonic commercial jet, which is being developed by Lockheed Martin, will have its flight test livestreamed as a demonstration of how quiet it can be in the air. The $247.5 million Quesst, whose name is short for Quiet SuperSonic Tech, will be shown on the livestream dramatically emerging from Lockheed Martin’s Skunk Works facility in Palmdale, California. NASA has been on a mission since 2018 to prove that its X-59 can fly over cities without producing noise pollution, or sonic booms. This test flight marks an important milestone in the six-year-old project.

The first flight will be streamed on January 12 at 4pm ET on YouTube, as well as the NASA app and the NASA+ streaming service.

The space agency said it will survey people about the noises they hear from the jet during the first flight. It did not specify how it would find these people, or many people it would poll. The data collected will be sent to regulators and used to help propose new rules that limit the use of supersonic jets. The US federal government has blocked all civilian supersonic jets from flying over land for over five decades.

When NASA first announced its quiet supersonic technology project in 2018, administrator Jim Bridenstine said, “This aircraft has the potential to transform aviation in the United States.” While the jet was supposed to first take flight in 2021, the debut today still marks a major milestone in the QueSST mission. By 2027, NASA expects to have more definitive results about how effective the new aircraft technology is at reducing flight noise.

If new laws are eventually passed that permit supersonic jet aircrafts to fly in close proximity to land, high-speed commercial flights could become a reality. Once NASA and Lockheed Martin finalize development of the aircraft, the agency said it will conduct safety evaluations for about nine months. After enough evidence is shared to prove that the Quesst aircraft can be flown safely, NASA plans to expand its flight tests to cities across the US and collect more information about the noise it produces through additional surveys.

Welcome back to our weekly gaming news roundup. 

January is a magical time in the video game industry. We’ve just closed out 12 months of marketing hype and shifting production timelines, and the year ahead is filled with the promises of new titles and fresh hardware. During this special month, we can look at the 2024 release calendar with excitement and optimism, before the delays start rolling in. So, let’s get to it — these hearts aren’t going to break themselves.

This week’s stories

Arcane season 2 teaser

You watched Arcane, right? The Netflix series set in the League of Legends universe debuted in late 2021 and it was an instant sensation, starring fan-favorite characters like Jinx, Vi and Caitlyn. The next season is set to come out in November and Riot dropped a one-minute teaser for it last Friday. The trailer has Singed experimenting on himself in a dreary laboratory, while a creature that looks like Warwick hangs above, connected to tubes and IVs. It’s gonna get dark, kids.

If you haven’t watched season one of Arcane, do that now.

This kid beat Tetris

I guess we can all stop playing Tetris. 13-year-old Willis Gibson became the first person to reach the killscreen in the classic NES version of Tetris, 34 years after the game’s debut. Gibson caught the moment on camera and honestly, it gives me goosebumps every time I watch it. The competitive Tetris scene has been steadily growing over the past few years, and players are using a new input technique called rolling that allows them to move pieces faster than ever. If you’re into this kind of thing, I recommend watching Classic Tetris Monthly on Twitch or YouTube.

Promises, promises

Before we get back into all the award shows and livestreams and media events this year, let’s take a look at the video game promises heading into 2024.

There’s nothing official yet, but it looks like Nintendo is preparing to release the Switch 2 in 2024, seven years after the launch of the original Switch, and right in the middle of the PS5 and Xbox Series X console cycle. According to early reports, the Switch 2 will be an iterative hardware update with slightly more processing power and support for DLSS and raytracing. The big news is that Nintendo has finally joined us in the 21st century, and players should be able to transfer their Switch games to the new console without any roadblocks.

Outside of the new Switch, 2024 is all about games. We know how this goes, right — in video games, a release date is really just the first step before a delay, so whatever you’re into, prepare for heartbreak over the next 12 months.

There are two games I’m confident will actually hit the market on their release dates in 2024, and that’s only because they’ve been in development for years and delayed multiple times already. Ubisoft’s open-world pirate simulator Skull and Bones is due out on February 16 for PS5, Xbox and PC, and Final Fantasy VII Rebirth will hit PS5 on February 29. Rebirth looks legit, while Skull and Bones … doesn’t.

Overall, we have a healthy lineup of titles to get excited about in 2024. First, on the mainstream front: 

January 18: Prince of Persia: The Lost Crown | Ubisoft Montpellier

January 19: The Last of Us Part 2 Remastered | Naughty Dog

January 26: Tekken 8 | Bandai Namco Studios, Arika

February 2: Suicide Squad: Kill the Justice League | Rocksteady Studios

February 2: Persona 3 Reload | P-Studio

February 16: Skull and Bones | Ubisoft

February 29: Final Fantasy VII Rebirth | Square Enix

March 22: Dragon’s Dogma 2 | Capcom

March 22: Princess Peach: Showtime! | Nintendo

March 22: Rise of the Ronin | Team Ninja

2024: Silent Hill 2 remake | Bloober Team

2024: Star Wars Outlaws | Massive Entertainment

2024: Avowed | Obsidian Entertainment

2024: Senua’s Saga: Hellblade 2 | Ninja Theory

2024: Concord | Firewalk Studios

2024: Paper Mario: The Thousand-Year Door | Nintendo

This isn’t a comprehensive list for the year in AAA gaming, but it’s a solid start. 

And then there are the games I’m personally looking forward to in 2024. Most of these still have vague release windows — it’s as if the developers didn’t want to give a timeframe at all, so they just whispered 2024 to their marketing teams and hoped no one would notice. But I did. I always do. I’m always watching.

Here are the games on my underground radar this year (again, this isn’t an exhaustive list because there are so many fantastic games nowadays, but these ones spring to mind):

January 16: Home Safety Hotline | Night Signal Entertainment

August 20: Black Myth: Wukong | Game Science

2024: Skate Story | Sam Eng

2024: Lorelei and the Laser Eyes | Simogo

2024: Baby Steps | Gabe Cuzzillo, Maxi Boch, Bennett Foddy

2024: The Plucky Squire | All Possible Futures

2024: Mewgenics | Edmund McMillen, Tyler Glaiel

2024: 33 Immortals | Thunder Lotus

2024: Thank Goodness You’re Here! | Coal Supper

2024: Despelote | Julián Cordero, Sebastian Valbuena

2024: Time Flies | Playables, Raphaël Munoz, Michael Frei

2024: Cryptmaster | Paul Hart, Lee Williams, Akupara Games

2024: Hades 2 | Supergiant Games

2024: Hyper Light Breaker | Heart Machine

When any of these titles is inevitably delayed, we can all gather right here and have a good cry. Let us know in the comments what you’re looking forward to this year and why it’s Hollow Knight: Silksong.

Now Playing

I’ve been sticking with local co-op games during these chilly winter months, and now I’ve moved on to Baldur’s Gate 3. I know, I know, everyone is already telling you to play it, but this pitch is strictly for the splitscreen crowd — Baldur’s Gate 3 is a joy to play alongside a loved one, as long as your cleric actually remembers to heal your party every now and then. You know who you are.
