Researchers developed an ultrasonic espresso process that uses high-frequency sound waves instead of hot water to produce espresso-strength coffee at room temperature. And, not only did coffee drinkers find it comparable to traditional espresso, but the brewing process cut energy use by up to 75%. An anonymous reader quotes a report from The Conversation: We have developed what we call an ultrasonic espresso: a room-temperature brewing process that uses high-frequency sound waves to extract the flavor, oils, aroma and caffeine from coffee grounds. The result is an espresso-strength coffee made in under three minutes, but needing far less energy than the conventional method. Saving up to 75% of energy by not heating the water is a minor benefit for home users or small coffee shops. But for companies making ready-to-drink coffee products at industrial scale, it could be very significant indeed. A concentrated room-temperature coffee could be used directly in bottled drinks, milk-based beverages or cold coffee products. It can also be shipped as a concentrate and diluted later. This would reduce not only energy use, but potentially processing time as well. The key to the new process is ultrasound. These are sound waves above the range of human hearing. In our system, a small metal device called a transducer presses against the side of a traditional espresso basket and makes it vibrate rapidly. Those vibrations move through the water and coffee grounds. This creates a phenomenon known as acoustic cavitation. Tiny bubbles form and collapse in the liquid. When these bubbles collapse near coffee particles, they produce microscopic jets and forces that act a little like scrubbing brushes. They pit and fracture the surface of the coffee grounds, helping flavor compounds, oils and caffeine move into the water much faster than they normally would at room temperature. In other words, ultrasound helps us replace heat with mechanical energy. [...] In earlier work, we used ultrasound to speed up cold brew dramatically. But the challenge in this project was different: could we produce something with the strength, body and intensity of espresso, without heating the water? To do that, we adjusted several variables. Brew ratio was one of the most important: how much water we used for each gram of coffee. Too much water and the drink becomes diluted; too little and extraction becomes difficult. Grind size also mattered. Finer grounds allowed us to extract flavor more rapidly. Finally, we tested how long the ultrasound should be applied. We found the sweet spot was about two-and-a-half to three minutes. Of course, making a concentrated coffee in the laboratory is one thing. The real test is whether people want to drink it. [...] For the espresso samples, participants could not reliably tell the traditional and ultrasonic versions apart. There were no significant differences in aroma, flavor, bitterness or overall liking. For filter coffee, the ultrasound version was actually preferred overall, with participants rating its bitterness more pleasantly.

Amazon MGM has dropped Luca Guadagnino's nearly completed Sam Altman biopic Artificial and is seeking another distributor for the film. The move comes months after Amazon expanded its multibillion-dollar partnership with OpenAI, fueling speculation about a potential conflict given the movie's reportedly unflattering portrayal of Altman. The Independent reports: Artificial would have marked the Oscar-nominated Call Me By Your Name director's third Amazon film, following the critically acclaimed Zendaya-led tennis romance Challengers (2024) and the academic scandal drama After the Hunt (2025), starring Julia Roberts. The new movie is said to chronicle the brief period when Altman was abruptly ousted as OpenAI's CEO in 2023 and subsequently rehired. Monica Barbaro and Ike Barinholtz star alongside Garfield as former OpenAI CTO Mira Murati and SpaceX founder Elon Musk, while Yura Borisov, Cooper Hoffman, Jason Schwartzman, Cooper Koch, Billie Lourd, Zosia Mamet, Angus Imrie, Chris O'Dowd, Mark Rylance and Margo's Got Money Troubles breakout Thaddea Graham round out the cast. It is unclear exactly why the film was dropped, but according to Variety, the news came after it had already undergone positive screen tests. An early viewer told the publication that the film's portrayals of Altman and newly minted trillionaire Musk are the two characters audiences would "like the least." It was also reported that Amazon had already seen every early iteration of the script before Guadagnino was hired to direct. Altman and Amazon founder Jeff Bezos have developed a high-profile friendship over the years. In fact, the former was in attendance at Bezos's wedding to Lauren Sanchez, which took place in Venice, Italy, in 2025. In recent months, the two have continued to deepen their professional partnership that began in 2015, when Amazon became one of OpenAI's first investors. Ten years later, the companies closed their first major deal in November 2025, allowing the ChatGPT maker to run its systems on Amazon's U.S. data centers.

Norway will largely prohibit generative AI use for elementary kids ages 6 to 13 beginning with the new school year, while allowing limited, teacher-supervised use for older students. The government says the restrictions are intended to prevent children from skipping foundational reading, writing, and mathematics skills amid declining test scores. Reuters reports: Facing a broad decline in education test scores, the government in 2024 banned smartphones from schools and has given teachers back more powers to enforce discipline in the classroom. Using AI increases the risk that young children skip important steps in their education, Prime Minister Jonas Gahr Stoere told a press conference on Friday. "The most important thing in school is that our children learn to read, write and do mathematics," Stoere said, adding that the new standards will be imposed from the new school year beginning in late August. Pupils from first through seventh grade, aged 6 to 13, should as a general rule not be using AI, while those in lower secondary school, aged 14 to 16, can cautiously adopt tools under teachers' supervision, the government said. In upper secondary education, from ages 17 to 19, students should learn to use AI appropriately so that they are prepared for further education and work, it added. In a related statement, the Norwegian government also said it would propose legislation to fund the use of more books in classrooms, reversing the trend towards computer tablets.

Video game composer and sound designer Bobby Prince has died at age 81 following an illness. Developer id software shared the news. Engadget reports: Prince was perhaps best known for his pioneering work on the Doom series. The Library of Congress inducted his soundtrack for the original game into the National Recording Registry just last month. "Despite the limitations of the 1993-era sound card drivers, Prince composed the perfect riff-shredding accompaniment for the game's demon-slaying journey to hell and back," the Library of Congress stated. "Taking advantage of his knowledge of MIDI, Prince even worked to ensure that the sound effects he created could cut through the music by assigning them to different MIDI frequencies." Prince also worked on games such as Wolfenstein 3D, Rise of the Triad and Duke Nukem 3D. In 2006, the Game Audio Network Guild honored Prince with a lifetime achievement award.

Hyundai Motor Group is acquiring SoftBank's remaining 9.65% stake in Boston Dynamics for $325 million, "closing out SoftBank's last piece of Boston Dynamics and turning the Waltham, Massachusetts robotics company into a wholly owned Hyundai business," reports Startup Fortune. From the report: The price is $325 million for the remaining stake, according to the deal terms, and it follows the put option SoftBank retained when Hyundai bought control of Boston Dynamics in 2021. You should read that as a signal, not a footnote. Hyundai paid about $880 million for an 80% stake in Boston Dynamics in the 2021 transaction, valuing the company at roughly $1.1 billion at the time. SoftBank had bought Boston Dynamics from Alphabet in 2017, after Google had acquired the robotics lab in 2013. It was a strange ownership path for a company whose robots became famous on YouTube long before they became obvious commercial products. That part is changing. At CES in Las Vegas on January 5, 2026, Hyundai and Boston Dynamics showed the electric Atlas humanoid robot in public, with the Associated Press reporting that the life-sized robot stood up, walked around the stage and was remotely piloted for the demonstration. The useful detail was not the stagecraft. It was the deployment plan. A production version of Atlas is expected to begin work at Hyundai's electric vehicle plant near Savannah, Georgia, by 2028. [...] If Hyundai can turn that into repeatable manufacturing value, the SoftBank exit will look less like a tidy cleanup and more like the moment Hyundai stopped borrowing a robotics future and decided to own it outright.

An anonymous reader quotes a report from Wired: A report from Canada's Transportation Safety Board has highlighted regulatory failures that allowed OceanGate's unregistered, unflagged, and uncertified Titan submersible to operate out St. John's, Newfoundland, for years before it imploded on a tourist trip to the wreck of the Titanic in 2023. "When it came to the Titan, critical information existed across multiple federal government organizations, but no one was responsible for connecting the dots," says TBS chair Yoan Marier in a statement. "Without a complete picture of the operation, the Titan continued to operate in Canada without regulatory oversight." [...] As OceanGate continued to operate from St. John's in 2021 and 2022, the Titan made successful dives to the Titanic and several sites within Canadian waters. The company eventually interacted with a total of 10 Canadian federal agencies, including Parks Canada, the Department of National Defense, and the Royal Canadian Mounted Police. But the company's operations were never directly reported to the team responsible for marine safety. "In terms of the actual people that were responsible for marine oversight, their focus was on the Canadian support vessel," says TSB investigator Jason Melvin. While TSB investigators did not have access to the wreckage of the Titan itself, which remains with the US Coast Guard, they did analyze portions of the carbon fiber left over from its manufacture. They calculated that a hull made to OceanGate's exact specifications might have been able to make hundreds of millions of dives to Titanic depths before failing. However, the composite samples as built had porosity and waviness between layers and were ground down in a way that might have introduced defects. When the TSB tested the compressive strength of the carbon fiber, it indicated the material could fail in as few as 30 deep dives. [...] The TSB is recommending increased oversight of the riskiest vessels and improvements in information sharing between departments, and is requiring that all human-occupied submersibles be subject to international construction and safety standards.

Researchers have disclosed a new unpatchable BootROM exploit affecting Apple devices with A12, A13, S4, and S5 chips. The attack requires physical USB access and DFU mode, but can let an attacker run code before iOS loads, bypass signature checks, and boot modified software. 9to5Mac reports the details: In a highly detailed technical post published today, the Paradigm Shift Team details usbliter8, a new exploit that "leverages both a hardware bug in the USB controller and a specific configuration flaw present in the device firmware" and cannot be patched. The PS Team explains that ahead of today's disclosure, it shared its findings and worked with Apple Product Security to coordinate the release. The researchers also thanked Apple's security team for its "prompt response, constructive engagement, and cooperation throughout" the process. In a nutshell, this bug affects the following Apple SoCs: A12, S4, S5, and A13. [...] They add that "technical support for A12X/Z is possible," but "it is not currently implemented." That could add the 2018 and 2020 iPad Pro lineups to the list. The way usbliter8 works is: it sends specially crafted data to a device over USB while it is in DFU mode, confusing the USB controller and causing it to write data to the wrong part of memory. That gives an attacker with physical access to the device control over its startup process. From there, they can run their own code before iOS loads, bypass signature checks, and boot modified system software. Importantly, the exploit does not affect or compromise the device's Secure Enclave, which in practice means that data such as passcodes and encrypted user data remain secure. That said, PS Team says that "although usbliter8 doesn't affect SEP itself, it opens up wider attack vectors to compromise the Secure Enclave," adding that "by releasing this exploit publicly, we hope to highlight the real-world impact of these hardware flaws and contribute to a broader understanding of modern SecureROM security." [...] Given that this is also an unpatchable exploit, the researchers note that "affected users should be aware that migrating to newer hardware remains the most effective mitigation."

The European Commission is reportedly preparing to provisionally classify Amazon Web Services and Microsoft Azure as "gatekeepers" under the Digital Markets Act, bringing cloud infrastructure under the law's stricter competition rules for the first time. The designation could require greater interoperability and data portability, making it easier for customers to switch providers, with a final decision expected by the end of 2026. Heise reports: This investigation began in November 2025, when the EU targeted the cloud power of US tech giants. The trigger was outages in cloud services with sometimes significant impacts on other internet services. Shortly before, an approximately 15-hour outage of the AWS cloud in the US meant that not only Amazon's own streaming services but also Atlassian, Docker, Epic Games, and the Signal messenger were unavailable or severely restricted. Shortly thereafter, Microsoft Azure also struggled with an outage, preventing air passengers from checking in and interrupting votes in the Scottish Parliament. As a result, European antitrust authorities have also scrutinized cloud services under the Digital Markets Act for the first time. The major cloud providers, primarily from the US, have so far evaded the EU's Digital Markets Act because a large part of their business is handled through corporate contracts. This makes it difficult to determine the number of individual users. However, this is one of the EU's most important criteria for determining the market power of companies. [...] As gatekeepers, AWS and Azure would be obliged to ensure interoperability and data portability. This would, for example, simplify switching cloud providers and allow customers to link other services with AWS or Azure clouds, instead of being limited to AWS and Azure offerings. Significant fines could also be imposed if the cloud services are found to be in violation of existing regulations.
