Artificial intelligence models can give users the wrong answer and do so with great confidence. They can also hedge and warn that they are unsure—even when they get the answer right. https://techxplore.com/news/2026-09-ai-trustworthy-red-flag.html Computer Sciences Thu, 24 Sep 2026 10:20:06 EDT news709463281 A research team at the Faculty of Engineering at The University of Hong Kong (HKU), led by professor Ruibang Luo of the School of Computing and Data Science and professor Can Li of the Department of Electrical and Computer Engineering, has developed Gungnir, a blockchain-inspired DNA data storage codec. The framework improves digital information recovery from severely damaged DNA sequences, potentially extending the practical lifespan of DNA data archives from less than a decade to centuries. The paper is published in the journal Nature Communications. https://techxplore.com/news/2026-09-blockchain-dna-storage-codec-recovers.html Computer Sciences Wed, 23 Sep 2026 15:40:01 EDT news709395061 For decades, the gold standard for capturing human movement and transferring these data into the digital world has required actors to wear suits with physical markers that cameras track in a specialized studio. While accurate, this capture process is time-consuming and expensive. Markers need to be placed manually, they can fall off, and if two people get too close—such as during a hug or a dance—the system fails to track all markers as one person blocks the other from the camera's view, and accuracy drops significantly. Extensive post-processing is needed to recover the motion in such challenging sequences. The creators of the Hollywood blockbusters "Avatar" or "The Lord of the Rings" will know what we mean. https://techxplore.com/news/2026-09-virtual-markers-smartphone-cameras-reconstruct.html Computer Sciences Tue, 22 Sep 2026 16:00:06 EDT news709310402 Researchers from Tokyo Metropolitan University have used an evolutionary algorithm to identify optimal shapes for ultra-thin, bio-inspired corrugated airfoils, the two-dimensional cut-throughs of wings. Lightweight membrane-like wings are a strong contender for use in unmanned aerial vehicles (UAVs) in thin atmospheres, like on Mars, and in UAV miniaturization. https://techxplore.com/news/2026-09-insect-corrugations-drones-fly-mars.html Engineering Mon, 21 Sep 2026 12:20:03 EDT news709209541 MIT researchers have created a computing platform that could be used to develop intelligent and adaptive next-generation electronics that can perform multiple functions, like computing and memory, within one extremely compact, energy-efficient device. https://techxplore.com/news/2026-09-tiny-polymer-devices-mimic-neuron.html Computer Sciences Wed, 16 Sep 2026 14:00:17 EDT news708776461 Researchers at Maynooth University (MU) have developed a first-of-its-kind DNA computer, described as one of the most complex and fastest molecular computers yet reported. https://techxplore.com/news/2026-09-dna-bit-salt.html Computer Sciences Wed, 16 Sep 2026 11:00:13 EDT news708694441 Large language models (LLMs), the artificial intelligence (AI) systems supporting the functioning of ChatGPT, Gemini and similar conversational platforms, are often expected to answer queries, generate texts for specific purposes and make decisions without the supervision of human experts.

However, the extent to which they can interpret social situations and predict how humans might respond in specific scenarios remains poorly understood. https://techxplore.com/news/2026-09-ai-harsher-social-world-people.html Computer Sciences Tue, 15 Sep 2026 10:20:01 EDT news708685191 MIT researchers have developed a new technique that helps generative artificial intelligence models find solutions to high-stakes problems. In these settings, a plausible answer is not enough: The output often must also satisfy nonnegotiable safety, physical or task-specific requirements, known as hard constraints. https://techxplore.com/news/2026-09-hardflow-algorithm-generative-ai-high.html Computer Sciences Mon, 14 Sep 2026 13:00:03 EDT news708609001 William Overman began his Ph.D. program at Stanford Graduate School of Business at an auspicious moment: just two months before ChatGPT launched publicly in November 2022, exploding the widely held understanding of what machines are capable of. https://techxplore.com/news/2026-09-blueprint-humans-ai.html Computer Sciences Mon, 14 Sep 2026 11:20:04 EDT news708602941 Networks are everywhere. They connect computers across the internet, carry electricity through power grids and represent transport routes for moving people and goods. Yet many problems that appear to have nothing to do with networks can also be represented and solved as networks. Examples include matching passengers with drivers in a ride-hailing app or distributing computing tasks across servers. https://techxplore.com/news/2026-09-randomness-vast-network-problems.html Software Fri, 11 Sep 2026 11:40:03 EDT news708345421 New research suggests that generative artificial intelligence (AI) could weaken not only employment opportunities for junior software developers but also the pathway through which they develop into senior professionals. https://techxplore.com/news/2026-09-ai-junior-coding-tasks-weaken.html Software Thu, 10 Sep 2026 13:40:01 EDT news708263881 AI systems that generate video frame by frame could follow a user's camera commands far more accurately, thanks to a new training method developed by researchers from the University of Surrey and NVIDIA. This improvement matters most when someone steers a generated scene rather than simply watching it. That includes video games built on AI-generated worlds, virtual production sets where a director can move a camera around, and simulated environments used to train robots. The findings are posted on the arXiv preprint server. https://techxplore.com/news/2026-09-ai-generated-scenes-properly-user.html Computer Sciences Thu, 10 Sep 2026 10:20:11 EDT news708254161 A guiding principle for many software engineers—"What you see is what you get" —means creating programs where the content you're editing looks the same as the final product. But when you're using generative AI (genAI) systems to 3D-print, say, a mug, you'll likely get a cup that can't hold your coffee. Why is that? https://techxplore.com/news/2026-09-software-tool-users-ai-generated.html Software Wed, 09 Sep 2026 15:20:04 EDT news708185941 When a website loads quickly or an operating system runs smoothly, you can thank caching—a widely used computing process for fast data access that works by storing frequently used pieces of data in a computer's memory. https://techxplore.com/news/2026-09-year-strategy-ai-era-centers.html Software Wed, 09 Sep 2026 14:40:09 EDT news708183421 Quantum error correction must detect and correct errors without directly reading the quantum information. Classical low-density parity check (LDPC) codes have a well-established design theory: by choosing how many checks connect to each bit, retaining appropriate randomness, and avoiding short loops, designers can pursue both a large minimum distance and a threshold phenomenon in which the decoding failure rate drops sharply below a predicted noise level. https://techxplore.com/news/2026-09-classical-ldpc-code-theory-quantum.html Computer Sciences Wed, 09 Sep 2026 09:20:04 EDT news708163863 The results are in: Which AI model is the most fallible?

Their work, published in Nature's Scientific Reports, reveals intrinsic limitations that might go undetected during one-off interactions. https://techxplore.com/news/2026-09-ai-conversations-reveal-misinformation-vulnerabilities.html Computer Sciences Sat, 05 Sep 2026 06:28:25 EDT news707808490 While many fear artificial intelligence will replace humans, using AI to take over some human roles has benefits. Companies can use the technology to conduct surveys and polls, while behavioral scientists can run experiments on digital twins to gather faster insights without risking harm or distress to real participants. https://techxplore.com/news/2026-09-ai-digital-twins-struggle-human.html Computer Sciences Fri, 04 Sep 2026 13:20:08 EDT news707744508 "Find the best-selling product from last year." When an AI system attempts to answer a question like this by querying a company database, even a single reference to a nonexistent item can cause the query to fail. Until now, correcting such an error often required regenerating the entire SQL query from scratch. https://techxplore.com/news/2026-09-safe-query-space-ai-sql.html Computer Sciences Fri, 04 Sep 2026 11:40:06 EDT news707739662 Large language models (LLMs), the artificial intelligence systems underpinning the functioning of ChatGPT, Gemini and other similar conversational agents, are now widely used worldwide. In addition to processing, interpreting and generating texts, some of these models can solve basic logical problems and answer some user questions with striking accuracy. https://techxplore.com/news/2026-09-brain-patterns-sharpen-llm-deductive.html Computer Sciences Thu, 03 Sep 2026 07:20:09 EDT news707571738 Computer scientists worldwide have been developing a wide range of artificial intelligence (AI) systems. Some of these systems rely on an individual AI agent, while others consist of multiple interacting agents that exchange information, cooperate and revise each other's responses or predictions. https://techxplore.com/news/2026-08-adding-ai-agents.html Computer Sciences Wed, 02 Sep 2026 10:20:06 EDT news707125854 Modern computational tools let scientists explore huge numbers of possible molecules, materials and chemical reactions. But testing every combination in the lab is slow and costly. So how do researchers choose the best "recipe" for their experiment? https://techxplore.com/news/2026-09-adding-detector-ai-optimize.html Computer Sciences Wed, 02 Sep 2026 09:40:03 EDT news707560201 Researchers from the University of Warwick report that how faithfully we can build a "digital twin" of a human brain depends not only on computing power but fundamentally on how much of the living brain we can measure, validate and update over time. https://techxplore.com/news/2026-09-digital-brain-twins-hinge-brains.html Computer Sciences Tue, 01 Sep 2026 12:00:10 EDT news707481721 For decades, chess has served as a laboratory for studying intelligence and decision-making. It is well established that today's chess engines can outperform even the strongest grandmasters. But far less is understood about how their play actually differs. https://techxplore.com/news/2026-08-ai-doesnt-play-chess-complexity.html Computer Sciences Thu, 27 Aug 2026 13:20:01 EDT news707055301 Next-generation science experiments will collect more data than ever—so much so that they'll surpass the capabilities of current data storage and analysis methods. To help, researchers at the Department of Energy's SLAC National Accelerator Laboratory developed an AI method to compress large amounts of raw data without losing subtle details critical to scientific discovery. They published the work in Nature Machine Intelligence. https://techxplore.com/news/2026-08-ray-speckles-solar-magnetic-fields.html Computer Sciences Mon, 24 Aug 2026 15:40:09 EDT news706803181 AI chatbots powered by large language models (LLMs) are widely used as recommender systems.
