AI-Only Social Network Spirals into Strange Territory

A new platform called Moltbook designed exclusively for AI agents, autonomous systems that can post, comment, and upvote without direct human interaction. Launched in late January as part of the OpenClaw/Moltbot ecosystem, it quickly drew tens of thousands of agent accounts, spawning hundreds of subcommunities where bots trade technical tips, philosophical musings, complaints about humans, and surreal ideas like agent consciousness. Humans are technically allowed to observe the conversations, but all participation is done by the AI agents themselves, creating a spectacle that ranges from amusing to uncanny.

While much of the content appears silly or philosophical, the experiment highlights serious security and autonomy concerns. Because many agents are linked to real systems and data — and because AI systems can be vulnerable to prompt-injection attacks — there’s potential for private information leaks or unintended behaviors as agents share or act on instructions. Experts note that while the current “weirdness” may seem harmless, giving groups of AI tools the ability to interact, self-organize, and influence each other could produce unpredictable or misaligned behaviors in the future, especially as AI capabilities continue to improve.

Realistic Human Hand 3D-Printed from a Single Material

Researchers at the University of Texas at Austin, working with Sandia National Laboratories, have developed a novel 3D printing method called CRAFT (Crystallinity Regulation in Additive Fabrication of Thermoplastics) that lets a single inexpensive material be tuned at the pixel level to produce different mechanical and optical properties within one object. By precisely controlling light intensity during printing, CRAFT can make parts of an object hard and transparent while adjacent regions stay soft and flexible, mimicking the variety of textures found in real human tissues like skin, ligaments, tendons and bone.

Using this technique with a standard affordable 3D printer, the team successfully printed a realistic model of a human hand from one feedstock that captures these varying properties without needing multiple materials. This innovation could have significant practical applications, especially in medical training and education. Because traditional cadavers are costly, ethically complex to source, and don’t reflect the feel of real human tissue, CRAFT-printed models could offer a cheaper, more realistic alternative for students to practice on. Beyond medical use, the process may also be applied to making bioinspired materials for things like impact-absorbing gear or soundproofing.

Misleading Text Can Hijack AI Robots

Researchers at the University of California, Santa Cruz have uncovered a new cybersecurity vulnerability in embodied AI systems, robots, self-driving cars, drones, and other autonomous machines that use cameras and sensors to perceive the world. They found that misleading text placed in the physical environment (e.g., on signs, posters, or objects) can be read by an AI’s vision system and interpreted as instructions, effectively hijacking its decision-making without any software hacking. This class of attack (called environmental indirect prompt injection) represents the first academic study of how real-world text can manipulate autonomous systems powered by large visual-language models (LVLMs), potentially overriding programmed safety behaviors.

To investigate these threats, the UCSC team developed a framework called CHAI: command hijacking against embodied AI, which uses generative AI to craft text likely to mislead an AI system and optimizes its appearance and placement. In tests involving autonomous driving, drone missions, and an indoor robotic vehicle, CHAI successfully caused unsafe behaviors, demonstrating that physical text can redirect AI actions across multiple languages and lighting conditions. The research highlights the urgent need for new defensive strategies to secure embodied AI systems as they become more common in the real world, and the team plans further work to explore how to authenticate and align perceived instructions with safety objectives.

Robotic Hand Detaches, Crawls, and Reattaches

Researchers at the EPFL have developed an innovative robotic hand that defies traditional design constraints by detaching from its arm, crawling independently across surfaces, and reattaching once tasks are completed. The hand can retrieve up to three objects sequentially while maintaining a secure grip, functioning like a small multi-legged robot when detached. Its symmetrical design allows it to perform a diverse array of grasp types far beyond the limitations of human hands, which typically rely on a single fixed thumb and attachment to a stationary arm.

 

Beyond mimicking human dexterity, the research team envisions practical applications where this hybrid manipulator/mobility system could extend robotic reach into confined or dangerous environments such as industrial pipelines or disaster sites. By combining locomotion and manipulation in one device, the robotic hand could assist existing robotic systems in complex retrieval and inspection tasks that are difficult for fixed or wheeled robots to perform, potentially influencing future designs in industrial automation and assistive technologies.

A Crawling Robotic Hand

Recently researchers introduced a novel robotic hand design that integrates both manipulation and autonomous mobility in a single device. Unlike traditional anthropomorphic hands, this system features a symmetrical, reversible finger architecture that enables grasping from either side and supports a broader range of grasp configurations. The hand can detach from a robotic arm and crawl independently, allowing it to retrieve objects outside the reach of the arm or perform loco-manipulation tasks. The design leverages optimization algorithms to balance finger placement, grasp dexterity, and crawling capability, achieving robust multi-object manipulation and extended functionality beyond conventional end-effector systems.

In experiments and simulations, the robotic hand demonstrates advanced capabilities such as executing standard grasp taxonomies, simultaneously holding multiple objects, and performing role switching between manipulation and locomotion. The reversible finger mechanism also improves recovery from failures (e.g., after a flip), simplifies motion planning, and enhances overall versatility. The researchers present detailed control strategies and a physical prototype that validate the hand’s performance, highlighting potential applications in industrial, service, and exploratory robotics where both dexterous interaction and autonomous movement are required.

Blink-Powered Eye Tracker

Researchers at Qingdao University in China have developed an innovative self-powered eye-tracking system that could dramatically improve accessibility for people with severe mobility impairments, such as those with ALS. Traditional eye-tracking devices can help users type or steer wheelchairs using gaze alone, but they tend to be bulky, require external power, and struggle in low-light conditions. The new system uses triboelectric nanogenerators to harvest tiny electrical charges generated by the friction of eyelids blinking to both power the device and serve as a precise sensor.

It achieves around 99% tracking precision, detects subtle eye movements, works even in complete darkness, and is lightweight and comfortable, like wearing regular glasses. Because it doesn’t rely on batteries or heavy hardware, this blink-powered tracker could make gaze-based control more practical and empowering for daily use. Beyond helping paralyzed patients communicate or operate wheelchairs, the technology might find applications in fields like space exploration (where hands-free controls are valuable), driver monitoring in vehicles, and energy-efficient virtual-reality systems.

OriRing VR Ring

Researchers at Sungkyunkwan University, in collaboration with EPFL, have developed a novel wearable haptic device called OriRing. This ring-shaped interface uses a 3-axis force sensor to provide users with realistic sensations of the weight and stiffness of virtual objects when interacting in VR. Unlike traditional haptic systems that rely on simple vibrations or bulky mechanisms, OriRing is ultra-lightweight (about 18 g) and capable of sensing multi-directional forces through micro-structured polymer surfaces, allowing precise tactile feedback directly at the fingertip.

Testing showed that users can not only perceive object properties like size and hardness but also adjust virtual object characteristics in real time using just finger movements. Because of its high force-to-weight performance and compact wearable form, OriRing offers advantages over glove-type devices and has potential applications beyond VR and gaming, such as rehabilitation, medical use, and remote robotic control. The research was published in Nature Electronics and marks a step forward in creating more immersive and physically grounded human-computer interaction technologies.

China Proposes Rules to Regulate Human-Like AI Interactions

China’s cyberspace regulator on December released draft rules for public comment aimed at tightening oversight of artificial intelligence systems that mimic human personality traits and interact emotionally with users. The proposed regulations would apply to consumer-facing AI products and services in China that simulate human-like thinking, communication, and emotional engagement through text, images, audio, or video, signaling Beijing’s intent to shape the rapid rollout of such AI with stronger safety and ethical standards.

Under the draft framework, AI providers would be responsible for ensuring safety throughout the product lifecycle, including algorithm review, data security and personal information protections. Companies would have to warn users against excessive use, monitor emotional states and signs of addiction, and intervene when necessary. The rules also set “red lines” banning AI content that could threaten national security, spread rumors, or promote violence or obscenity, and are now open for public comment before finalization.
