New 3D device harnesses living brain cells for computing

Curated by Shubham · TechCapsules · Apr 28, 2026

AI-summarised brief · reviewed before publication

Princeton researchers have developed a 3D device that combines living brain cells and advanced electronics for computing. The device features 70,000 biological neurons networked on a 3D mesh with dozens of microscopic electrodes. This approach enables the recording and stimulation of neurons' electrical activity at a finer scale than past methods, allowing for the recognition of patterns using computational techniques. The system was tested and successfully distinguished between distinct spatial and temporal patterns.

💡 Why It Matters

· This technology could help us understand the computing secrets of the brain - and apply that to the development of efficient AI systems.
· The opportunity is huge as our brain consumes roughly a millionth of the power consumed by existing AI systems to complete a similar task.

Nearly half of American adults now use AI, but concerns are also…

New research by the Pew Research Center reveals that nearly half of American adults (49%) now use AI chatbots, such as ChatGPT or Gemini, marking a significant increase from last year's 33%. Americans are using AI for various tasks, including researching information, handling work tasks, and entertainment. ChatGPT dominates the U.S. AI market, with 44% of respondents using the OpenAI chatbot. However, concerns about AI's impact on society and data security remain high, with 40% believing AI will be more harmful than beneficial and 71% expecting AI to make their personal information less secure.

💡 Growing AI adoption raises questions about accountability and regulation, as Americans lack confidence in both the government and AI companies to develop and use these tools responsibly. The widespread skepticism about AI's impact on society highlights the need for more transparent and effective regulation to address concerns about data security and societal benefits.

Apple’s AI agents in Xcode 27 make vibe coding easier

Apple has unveiled Xcode 27, a developer tool that integrates artificial intelligence (AI) to simplify the coding process. The new version of Xcode includes a Core AI framework that allows developers to use on-device AI models with ease, delivering strong performance through a modern Swift API. Xcode 27 also supports third-party AI models and enables developers to have conversations with AI agents, making it easier to create and edit code. This marks a significant shift in Apple's approach to AI, positioning it as a powerful extension of the coding process.

💡 Apple's emphasis on AI in Xcode 27 raises questions about the future of human interaction in app development. By portraying AI as a tool to augment human capabilities, rather than replace them, Apple may be trying to alleviate concerns about job displacement. However, the company's decision to showcase AI-generated apps and code may ultimately lead to a surge in "vibe-coded" apps, challenging the notion that human touch is essential in app development.

Elon Musk predicts Grok will start to challenge Hollywood by the end…

Elon Musk has announced that xAI's model, Grok, will be capable of creating full movies by the end of 2026. A trailer for Homer's The Odyssey, created using Grok Imagine Video 1.5, showcases the AI's rapid strides in video generation. The 2-minute-plus trailer features 36 consistent shots, realistic special effects, and emotional depth, demonstrating Grok's capabilities in scale, physics, and cinematic workflow. Musk believes Grok will be "watchable" by the end of 2026 and "really good" by 2027.

💡 Hollywood's dominance may be challenged by AI-generated content, as Grok's capabilities raise questions about the future of cinematic authorship.

Satellite AI Inference Clears Orbit: Gemma 3 Ran Aboard YAM-9 in April

Loft Orbital's YAM-9 spacecraft successfully demonstrated the first publicly disclosed execution of a vision-language model in orbit. Aboard the spacecraft, Google DeepMind's Gemma 3 performed natural language queries, classified Earth imagery, and produced plain-English summaries without transmitting raw pixels to the ground. This achievement marks a significant shift in the value layer of Earth observation, moving from ground-based processing to onboard inference capabilities. The model, running on an Nvidia Jetson Orin AGX graphics processing unit, utilized a software harness developed by NASA's Jet Propulsion Laboratory to fit within the spacecraft's memory budget and processing constraints.

💡 This breakthrough enables Earth observation satellites to operate more autonomously, reducing reliance on ground-based processing and potentially leading to faster and more efficient analysis of satellite imagery.
