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 $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.

Concerns over how the chat app has yet to become profitable have played a role in the decision. CEO Jason Citron said that staff across departments will be impacted once the layoffs begin.
According to the memo, Citron believes the company hired too many people since 2020. This, he wrote, led the workforce to take on projects that made Discord “less efficient.” He added that the company needs to sharpen its focus, however, he did not give any insight about any particular strategies moving forward except that the cuts “put us in the best position to continue building a strong and profitable business."
Discord will continue to provide short term pay and benefits to the 170 staffers it is letting go. This also isn't the first time the company has resorted to staff cuts. The company recently laid off four percent of its staff at the end of last year and before that, it made an undisclosed number of staffing cuts 2019.
The company has notably endured some internal struggles lately. Discord refused to have its CEO testify about its children protection policies when called upon by the US Senate Judiciary Committee. That came after a damning NBC News report on the issue, which claimed that children on the platform were being groomed and extorted. It also faced backlash for a small data breach that exposed the personal information of some users last year.
Discord is far from alone among tech companies which have recently initiated layoffs. Just one month into the new year, Duolingo and Unity announced they would be trimming staff. In big tech, Meta, Amazon and Google also have also announced plans to lay off hundreds of workers.

The claims process, which was previously set to end in January of this year, was initiated in September of 2023 after the regulatory agency finalized a settlement against Epic Games. About $245 million were earmarked for refunds alone.
The FTC said it notified about 37 million eligible Fortnite users impacted by the company’s practices when the claims initially opened. The agency said it will continue emailing potential refund recipients until the new deadline ends on February 29.
The online claim form is available on the official FTC website, where you will need to share your Epic account ID and disclose whether or not you received an email from the regulator. To qualify for a refund, you must have been charged in-game currency for products in the Fortnite game you didn't intend to purchase between January 2017 and September 2022. This also applies to children who were subject to charges using their parent's accounts without adult supervision between January 2017 and November 2018.
Importantly, the FTC highlights the fact that some charged users had their accounts locked after seeking support through Epic Games or after attempting reconciliation of charges with their credit card companies. This new extension comes as another blow to Epic Games, which was accused of violating the Children’s Online Privacy Protection Act Rule in a separate ruling.
The company has changed its policy on saving payment information as a result of the FTC claims case and will now offer a more direct way to offer yes or no options to save payment-related user information. In a statement, the company notably remarked, “No developer creates a game with the intention of ending up here.”

Honda said it will develop a model based on the Saloon concept car for North American markets in 2026, before it eventually reaches other buyers in Asia, Europe, the Middle East, South America and Africa. Additionally, the carmaker debuted a redesigned 'H' logo that will be exclusive to its EV lineup.
The Saloon, which is its flagship concept EV, has an aerodynamic design and rides low to the ground. While the Space-Hub is quite a bit boxier and renders show it with seating that has passengers facing each other. Besides touting a spacious cabin, Honda did not share much about when or if it plans to actually manufacture a car inspired by the Space-Hub concept.
The first entries in Honda’s 0 Series lineup will feature advanced driver-assistive systems that pair with the carmaker’s Sensing Elite software. In the latter part of the decade, Honda expects the 0 Series to gain automated driving features through the integration of AI.
Around the same time the company expects to implement dramatic improvements to its battery technology, like fast charging from 15 to 80 percent in around 15 minutes and reducing battery degradation to less than 10 percent over 10 years. Those are bold goals, especially for a company that is a little late to the EV space.
