MAUI, Hawaii — Engineers have built a first-of-its-kind artificial intelligence (AI) audio chip for wearable devices that they say will let users engage with AI assistants without needing to maintain a smartphone connection. Devices with the new chip will also harvest audio ‪—‬ and even video ‪—‬ data from the world around you to better serve these virtual agents.The new chip, called Snapdragon Sound Elite Gen 2, will pave the way for new features that are currently unavailable directly in portable devices such as headphones, smart glasses and speakers. Qualcomm representatives announced the new chip at the company's annual Snapdragon Summit, hosted here Sept. 21-24. Unlike current earbuds, devices with the new chip will be able to host apps right on the memory of the devices themselves, without relying on a continuous smartphone connection, as well as sync with cloud-based services like ChatGPT when connected to Wi-Fi. In practice, the chip will enable users to make vocal queries and requests, with an AI model taking actions such as setting up entries in an online calendar or making online purchases. Unlike existing devices that can perform similar functions, this would be possible without a smartphone connection.Beyond earbuds, company representatives want to integrate the chip into other "hearables," such as over-ear headphones, open-ear audio devices, audio glasses, camera buds (headphones that use tiny built-in cameras) and hearing devices, as well as "future personal AI wearables," like pendants or clips.What features will the chip enable, and how does it work? For users who wish to connect hearables to a smartphone or computer (to interact with a visual user interface, for example), the new chip uses a specialized component within the platform to establish connections over micropower Wi-Fi channels alongside Bluetooth. This technology harnesses architectural improvements at the chip level to consume much less power than standard Wi-Fi connections — but at the expense of higher latency and lower peak speeds. For audio devices, however, using Wi-Fi rather than Bluetooth generally improves playback quality, given that Bluetooth compresses data during transmission, Qualcomm representatives said. Adaptive and selective active noise cancellation also means users can filter out audio on command. For example, it allows listeners to hear key sounds, such as emergency sirens, while walking through a city or highlight people's voices during a conversation, while blocking out everything else. This noise cancellation is achieved through standard machine learning algorithms, rather than transformer-based large language models that power AI systems like ChatGPT.Devices could also allow lossless audio streaming — a high-quality audio standard that's usually available only if you subscribe to premium streaming services, like Spotify or Tidal — thanks to another built-in subsystem.

With contextual awareness, the system would constantly monitor the user's environment to harvest data to add to a personal profile, which representatives say helps it answer future queries. Although the system is audio-centric, it's also built to interface with hardware that includes sensors and cameras — like earbuds with built-in lenses that passively capture footage of a wearer as they go about their daily lives. This forms part of the data harvesting to build contextual awareness for the agentic AI systems people can access. Qualcomm representatives attempted to assuage privacy concerns by saying camera lenses on future earbuds would be low resolution and wouldn't identify specific individuals due to an AI mask that automatically obfuscates them. There's no information yet about the likely impact of these features on battery life compared with conventional non-AI devices. But Qualcomm representatives noted that device makers will no longer need to choose between audio quality, AI features and battery life. That said, Andrew Laister, staff product manager at Qualcomm, added in a media Q&A session that there's likely to be an impact on how a user experiences battery drain. That's because, unlike conventional earbuds that are used sporadically for calls and music playback, these new devices are designed to be used continuously. How does Qualcomm's new AI chip compare with similar technologies?AI-enabled headphones already exist in some capacity. For example, manufacturer Viaim launched its Rise and RecDot devices this year. These are designed to record, transcribe, translate and summarize conversations, although details on the chips powering them are not publicly available. Apple's AirPods, for example, let users tap into the Siri AI system, but they require a continuous iPhone connection to perform complex tasks. Devising smart audio features and getting them to work in real devices have also been at the heart of several recent research projects. For example, in 2024, University of Washington scientists embedded a computing system into off-the-shelf earbuds to zero in on individuals speaking in noisy environments while blocking all background noise. The previous year, the research team put a deep learning system into headphones so wearers could use voice commands to engage with a selective active noise cancellation system, choosing which sounds to hear and which ones to block out. Other companies have explored building new kinds of digital audio platforms for headphones. Three years ago, xMEMS unveiled Cypress, an audio chip that generates ultrasonic sound using the "piezoelectric effect," in which a material moves when a current is applied to it. Although the chip entered "mass-production readiness" in September 2025, consumer devices fitted with the platform have yet to be announced. Apple also may be working on a similar technology. This could manifest as AirPods with built-in cameras that will perform similar data harvesting as users go about their day-to-day lives, according to Bloomberg Managing Editor Mark Gurman. It's like the first smartphone moment with the Play Store.Andrew Laister, staff product manager at Qualcomm.Qualcomm's new chip is a spiritual successor to the 3-year-old Snapdragon S7 Gen 1 system, which featured in devices such as the Xiaomi Buds 5 Pro series. The previous chip also used AI for conventional active noise cancellation, audio customization and lossless audio streaming while connecting to devices via micropower Wi-Fi.However, the new chip has twice the AI power, completing 128 billion operations per second, compared with the previous one's 64 billion operations per second. It also uses 40% less power and is 30% smaller. A crucial aspect of the new system is its capacity to store apps on the device itself in the chip's onboard memory. Because the device will have its own IP address, it can communicate with servers using the https protocol, without needing to go through another phone or computer.Related storiesArtificial superintelligence (ASI): Sci-fi nonsense or genuine threat to humanity?Why is AI going on a hacking spree?Google scientists removed a critical 'consciousness safeguard' from AI in a new study. What happened next?Laister told journalists in the Q&A session that the company is currently scoping out whether the device could run two apps in RAM (short-term memory) at once — an AI agent and an audio streaming platform, for example — while keeping the rest in flash memory (long-term storage). He added they had to overcome a communication hurdle with micropower Wi-Fi foron the launch of the previous chip (specifically, that its power consumption is on a par with Bluetooth's). Now, he said the communication hurdle is actually being able to run apps on the device."It's like the first smartphone moment with the Play Store, but in this sense, that app store for your earbuds is currently owned by the device maker," he added. "They will be the guys that will choose which apps they will pre-bundle, and then we'll go from there."No details were available on when the system is likely to be found in devices, but representatives said Qualcomm is working with other companies, including HP and Bose, to explore headphones and speakers that feature the chipset.

NASA is moving forward with designing a new space telescope that can see even deeper into the infrared universe than the James Webb Space Telescope (JWST) can. The new mission, called PRIMA (Probe far-Infrared Mission for Astrophysics), is continuing its development to Phase B — the preliminary design and tech phase — according to a NASA statement. Managers will review the mission's progress before officially beginning the telescope's journey to launch; if all goes to plan, PRIMA will embark on a five-year mission no earlier than 2033.PRIMA's objective is to use a 5.9-foot [1.8 meters] telescope to examine the cosmos in the far-infrared, in a different set of wavelengths than the more famous JWST, which launched in 2021. (Other telescopes, such as Hubble and the newly launched Nancy Grace Roman Space Telescope, can also see some infrared wavelengths, but JWST was specifically designed to detect near- and mid-infrared light.) PRIMA's mission focus will be to uncover more information about exoplanet origins, galaxy growth and black hole evolution. "The key science questions that PRIMA aims to address in relation to planet formation are to quantify the role of water in driving planet formation, [and to] determine the total gas masses and carbon and oxygen abundances in disks to reveal where exoplanets form," Meredith MacGregor, an associate professor of physics and astronomy at Johns Hopkins University who studies how planetary systems form, told Live Science in an email. "We can't actually address these science questions with JWST," MacGregor added, "because the spectral lines that are required are only in the far-infrared — longer wavelengths than JWST is sensitive to."The University of Maryland (UMD) and Caltech, which helped develop the mission, each issued statements about the upcoming work."I'm most excited about the things I don't yet know," Alberto Bolatto, an observational astronomer at UMD and a co-investigator who leads galaxy evolution research for PRIMA, said in a statement. "I am elated to be part of the future of astronomy — to produce an instrument that is going to be an enormous tool for the astronomy community to move humanity's knowledge forward.""I am particularly excited about how PRIMA will help us discover and understand the role of powerful molecular outflows in galaxies over cosmic time, and how they shape star formation and the growth of supermassive black holes in the centers of galaxies," Lee Armus, a staff scientist at Caltech and the PRIMA co-investigator and science operations lead, said in a separate statement.Dawn of the Probe ExplorersPRIMA has a project cost cap of $1.2 billion, excluding launch and other nonproject expenses; for comparison, JWST cost $10 billion at launch in 2021, not accounting for inflation or launch expenses.PRIMA is also the first in a new class of spacecraft that NASA is calling Probe Explorers, which are meant to sit somewhere in between flagship, JWST-style missions and smaller agency efforts. Probe Explorers are a part of the decades-old Explorers Program that began with the Explorer 1 launch in 1958 and followed with more than 100 missions. Explorers perform "a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe," according to the agency.Explorer 1 (seen here) was the first satellite launched by the U.S. when it lifted off January 31, 1958. (Image credit: NASA/Joel Kowsky)The Probe Explorers were implemented after a recommendation from astrophysicists through the 2020 Decadal Survey, which is a consensus report issued by the National Academies of Sciences, Engineering, and Medicine on behalf of the community. NASA funded two concepts at $5 million apiece in 2024 and considered both PRIMA and the Advanced X-ray Imaging Satellite before announcing the decision to proceed with PRIMA this week.related stories60 million stars: Euclid space telescope snaps the most detailed photo of the Milky Way ever taken48 jaw-dropping James Webb Space Telescope photos'We are on our way to groundbreaking science': Stars turn neon-green in first test image from NASA's Roman telescope"NASA selected PRIMA for development after detailed evaluation of concept studies for Probe Explorer missions, based on their scientific merit in alignment with the Decadal Survey's recommendations, feasibility of their development plans on cost and schedule, and use of technologies that could support the development of future large missions," the agency stated Wednesday (Sept. 23).Should the mission fly as hoped, NASA's Jet Propulsion Laboratory will manage PRIMA, with contributions from numerous other NASA centers and international agencies.

The finding marks a milestone in AI companies' push to become more involved in life science research.

In our own solar system, all eight planets orbit our Sun in a nice, orderly fashion. None are more than 7° or so out of alignment with the equator, and all of them rotate in the same direction as the Sun itself. But that’s not the case for all solar systems, and a new paper published in Astronomy & Astrophysics from a team of researchers led by Yann Carteret, a PhD student at the University of Geneva (UNIGE), describes the first time we’ve ever found an exoplanet orbiting the opposite direction of its red dwarf parent star - and it has major implications for our understanding of planet formation theory.

The next few weeks offer plenty of celestial spectacles for the amateur astronomers among you to enjoy.
