MIT engineering professor Markus Buehler said he handed three Grok bots just two inputs: four unrelated reference photos and a mechanics question about how hierarchy, redundancy, disorder, and interlayer strength affect stiffness, peak load, energy absorption, and the shift from brittle fracture to progressive failure under a fixed material budget. Roughly 20 minutes later, the system had built an interactive 2D hierarchical Euler-Bernoulli beam-network lab, including a physics simulator it wrote from scratch and named HIER-FRACTURE v1.0.0. After passing nine self-checks in 220 milliseconds, it ran 47 simulations, with six held out for testing. The workflow then moved into manufacturing. A 3D-printing bot used Bambu Studio, connected to a printer named Leonas3DP, scaled two selected designs by 50x, sliced them, sent the job, and watched the live camera feed as the machine printed two plastic parts weighing 19.48 grams in total in under an hour. According to Buehler and the original report, the result points to a lower-cost route into physical experimentation: rather than relying on robotic arms or custom hardware interfaces, the bots operated the same graphical software humans already use.

PA Daily’s latest roundup spans crypto markets, regulation, AI, funding, and whale activity. OpenAI formally introduced GPT-6 Astra and said the model may sit close to the point where artificial general intelligence becomes recognizable in hindsight. Nvidia, meanwhile, agreed to acquire AI platform Hugging Face for about $13 billion, a deal that would put its three French co-founders into the billionaire ranks while preserving Hugging Face’s open-platform model, according to the report. In crypto, spot Bitcoin ETFs posted $731 million in net inflows on Sept. 3 U.S. time, led by BlackRock’s IBIT at $454 million. Spot Ether ETFs added another $141 million. Polymarket launched perpetual contracts across crypto, equities, and commodities, while Ethena said its fee switch proposal passed unanimously, clearing the way for programmatic ENA buybacks. The report also tracks a sharp response from AMC CEO Adam Aron, who said Robinhood’s tokenized stock plan involving AMC and more than 190 companies was unauthorized and unregistered under U.S. securities law. Elsewhere, a Guangzhou court ruled that a virtual-currency lending contract was invalid and said losses should be calculated using acquisition cost. Binance Alpha listings, funding for Diameter Pay, Oura’s U.S. IPO filing, and a series of high-return meme-token trades also featured in the day’s developments.

Binance Alpha will remove 14 tokens from its platform on September 4, 2026 at 08:30 UTC, according to an official announcement. After delisting, users can still withdraw or sell these tokens through BinanceAlpha or BinanceWallet.

Binance Alpha announced the removal of 14 tokens, including MTP, BDXN, TALE, and others. Users can still withdraw and sell the tokens after removal.

A legal analysis published by Internet Law Review examines a question that is moving closer to real-world deployment as AI agents begin handling tasks for users inside third-party apps and websites: is explicit user authorization enough, or must the operator of the app or website also give permission? The article, republished by MarsBit, breaks the issue into two technical paths. Under an API-based model, the platform must open interfaces, define access rights, and authenticate the service provider, which means the agent service can only function with both the user’s authorization and the platform’s cooperation. In that setting, “dual consent” exists as a practical reality. Under a GUI-based model, by contrast, the agent runs through the user’s own device, reads on-screen content through screenshots, OCR, and interface recognition, and simulates clicks and typing without its server directly connecting to the third-party platform. The piece argues that this makes the agent closer to a tool used by the customer than an independent actor or legal proxy. It also reviews platform terms that ban or restrict AI agents, saying their enforceability should be judged under China’s Civil Code rules on standard-form clauses, with close attention to notice obligations, scope, and whether the clause unreasonably strips users of core rights.

OpenAI's GitHub repository has shown signs of GPT-6, with a developer submitting a pull request that adds two environments (gpt6-js-image and gpt6-py-image) for the Computer Use project. Sam Altman said Astra marks a milestone where AI models can operate computers at a human-like level.

Doubao Work has finally gained two capabilities: parallel multi-agent execution and local computer-operation support on macOS. With the first feature, a single complex task can be broken into smaller pieces and split across several sub-agents. Each sub-agent then works on a different module at the same time, and whatever they produce is gathered into one deliverable when the whole job is done. The second feature brings Mac in line with Windows. GUI-based operation had already arrived on the Windows side, where Doubao Work can interact with the software shown on screen. On Mac, similar control only worked inside a browser until now. The refreshed macOS client can identify local interface elements itself, which lets Doubao Work complete a task by following on-screen steps even when the target program offers no MCP, API, plugin, or CLI hooks. BlockBeats relayed the news in a 7x24 flash update.

SlowMist said a Rust supply chain attack affected three legitimate libraries: arrayref@0.3.10, internment@0.8.7 and append-only-vec@0.1.9. The compromised versions introduced a malicious dependency called proc-macro1 that can automatically download and run cross-platform malware during Cargo builds. SlowMist also said arrayref’s older clean release, v0.3.9, had about 152 million downloads, but that usage does not mean any project or host has been compromised. The group advised users to inspect Cargo.lock files, verify resolved versions, rotate exposed credentials if needed, and rebuild affected systems in a trusted environment.
